RESUMEN
ABSTRACT Purpose: To develop a simple, subjective, and reliable grading scale for isotretinoin-induced meibography changes. Methods: After analyzing meibography images obtained from systemic isotretinoin users, a grading scale was proposed and named "meibography health score." The score ranged from 1 to 3, with decreasing gland reflectivity and identifiable margins. A total of 11 medical professionals were asked to grade 10 meibography images obtained from isotretinoin users using the proposed scale and were divided into three groups: (A) ophthalmologists with experience with meibography, (B) ophthalmologists with no experience with meibography, and (C) radiologists. The kappa statistic was determined to test interrater reliability. Results: The overall kappa was approximately 0.64. The kappa scores for Groups A, B, and C were 0.78, 0.59, and 0.90, respectively. Grade 2 had the lowest kappa scores (0.62, 0.35, and 0.82 for A, B, and C, respectively) and grade 3 the highest (0.78, 0.90, and 1.0 for A, B and C, respectively). Furthermore, Group C had the highest kappa scores and Group B the lowest. Conclusion: The meibography health score exhibited good interrater reliability, particularly in severe cases.

PURPOSE: The aim of this study was to evaluate the quality of life (QOL) after intrastromal ring implantation in patients with keratoconus. METHODS: This was a prospective, randomized, interventional study. We analyzed 60 eyes of 30 patients aged 16 to 35 years who were treated at the Department of Ophthalmology and Visual Sciences, Federal University of São Paulo, Brazil. The Visual Function Questionnaire (VFQ-25) and Short-Form 36 Questionnaire (SF-36) were used before intracorneal ring segment (ICRS) implantation and at 3, 6, and 12 months after surgical intervention. RESULTS: The mean corrected visual acuity improved from a mean of 0.32 ± 0.2 logMAR (20/40) preoperatively to 0.14 ± 0.11 logMAR (20/25) 1 year postoperatively ( P = 0.001). The mean spherical equivalent varied from -7.24 ± 3.47 preoperatively to -4.13 ± 2.41 postoperatively ( P = 0.001). The overall composite score for the VFQ-25 improved from 55.1 preoperatively to 80.4 1 postoperatively ( P = 0.001). SF-36 showed statistically significant improvement in all scores. When analyzing the correlation between visual acuity and VFQ composite score, a significant correlation was found between both variables (Pearson correlation coefficient of -0.40, P = 0.001). CONCLUSIONS: Patients with keratoconus had increased psychological symptoms and lower QOL and improved psychosocial criteria associated with corneal remodeling and decreased visual dependence on others after surgery. Extrapolation of these data to the whole keratoconus population suggests that ICRS implantation could improve QOL in these patients.

ABSTRACT Purposes: This study aimed to determine the association of the long-term refractive outcomes of cataract surgery with self-reported visual function obtained using Catquest-9SF. Methods: Patients recruited from the cataract outpatient clinic of VER MAIS Oftalmologia underwent a complete ophthalmologic examination. Patients who were diagnosed with cataract with indications for phacoemulsification and intraocular lens implantation received the Catquest-9SF questionnaire before and after surgery at 30 days and 1 year. Results: A total of 133 patients were recruited, but 32 patients were lost to follow-up; finally, data from 101 patients (48 men, 53 women) were analyzed. The crude variance explained by the data was 69.9%, and the unexplained variance in the first contrast was 2.39 eigenvalues (>2); thus, these results are different from those expected from random data. The people separation index was 2.95 (>2), and the people trust value was 0.9 (>0.8). These indices were evaluated in the assessment of skill levels. Visual acuity was the main variable that correlated with the Catquest score. Conclusions: The Catquest-9SF translated into Portuguese proved to be a one-dimensional and psychometrically valid tool to assess visual dysfunction in patients with cataract, and it is successful in objectively quantifying improvements after surgery. The results of this tool could be predictive and concordant of visual acuity improvement.
RESUMO Objetivo: Associar os resultados refrativos a longo prazo da cirurgia de catarata e a função visual autorreferida pelo questionário Catquest-9SF. Métodos: Paciente recrutados no ambulatório de catarata da VER MAIS Oftalmologia, foram submetidos a exame oftalmológico completo. Após diagnóstico de catarata com indicação de tratamento cirúrgico com facoemulsificação e implante de lente intraocular, o questionário foi aplicado antes da intervenção, 30 dias após cirurgia e 1 ano após, novamente. Resultados: Foram recrutados 133 pacientes. No decorrer do seguimento, 32 pacientes foram perdidos e ao final foram analisados os dados de 101 pacientes, dos quais 48 foram homens e 53 foram mulheres. A variância bruta explicada por dados foi de 69,9% e a inexplicada em primeiro contraste por 2,39 eigenvalores, sendo maior que 2, o que nos mostra que são resultados differentes dos esperados de dados aleatórios. O índice de separação de pessoas foi de 2.95 (>2) e o valor de confiança de pessoas foi de 0,9 (>0,8). Estes índices são os valores mínimos aceitáveis na diferenciação de níveis de habilidade. Acuidade visual foi a principal variável correlacionada com o score do Catquest. Conclusões: O Catquest-9SF traduzido para o português se demonstrou unidimensional e uma ferramenta psicometricamente válida para avaliar disfunção visual em pacientes com catarata, além de ter tido sucesso para quantificar objetivamente melhoras após a intervenção cirúrgica. Essa ferramenta pode ser utilizada como preditiva e concordante da melhora da acuidade visual.
RESUMEN
ABSTRACT Purpose: This study aimed to evaluate the pre-sence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) RNA in the ocular surface of individuals clinically suspected of coronavirus disease 2019 (COVID-19) and determine the accuracy of different approaches of molecular testing on the ocular surface based on the nasopharyngeal positivity status for COVID-19. Methods: A total of 152 individuals with suspected COVID-19 symptoms who simultaneously underwent nasopharyngeal and two different tear film collection techniques for quantitative reverse-transcriptase polymerase chain reaction (RT-qPCR) were included. Tears were collected and randomized: one eye had the filter strip for the Schirmer test and the contralateral eye had conjunctival swab/cytology in the inferior fornix. All patients underwent slit lamp biomicroscopy. The accuracy of various ocular surface collection techniques used for the detection of SARS-CoV-2 RNA was determined. Results: Of the 152 patients enrolled in the study, 86 (56.6%) had COVID-19 confirmed by nasopharyngeal PCR. Both tear film collection techniques detected viral particles: the Schirmer test was positive in 16.3% (14/86) and the conjunctival swab/cytology in 17.4% (15/86), with no statistically significant differences. No positive ocular tests were found among those with negative nasopharyngeal PCR tests. The overall agreement of the ocular tests was 92.7%, and in combination, the sensitivity would increase to 23.2%. The mean cycle threshold values in the nasopharyngeal, Schirmer, and conjunctival swab/cytology tests were 18.2 ± 5.3, 35.6 ± 1.4, and 36.4 ± 3.9, respectively. Compared with the nasopharyngeal test, the Schirmer (p=0.001) and conjunctival swab/cytology (p<0.001) tests had significantly different Ct values. Conclusion: The Schirmer (16.3%) and conjunctival swab (17.4%) tests were comparably capable of detecting SARS-CoV-2 RNA in the ocular surface by RT-PCR accurately based on nasopharyngeal status and demonstrated indistinct sensitivity and specificity. Simultaneous specimen sampling and processing from the nasopharyngeal, Schirmer, and conjunctival swab/cytology tests demonstrated significantly lower viral load in both ocular surface approaches than in the nasopharyngeal test. Ocular manifestations detected by slit lamp biomicroscopy were not associated with ocular RT-PCR positivity.
RESUMO Objetivo: Avaliar a presença de RNA de coronavírus 2 causador de síndrome respiratória aguda grave (SARS-CoV-2) na superfície ocular de indivíduos clinicamente suspeitos com COVID-19 e determinar a precisão de diferentes abordagens de testes moleculares na superfície ocular com base no status de positividade do RT-qPCR de nasofaringe para COVID-19. Métodos: 152 indivíduos com sintomas suspeitos para a COVID-19 foram submetidos a coleta de reação em cadeia da polimerase de nasofaringe simultaneamente a duas técnicas diferentes de coleta de filme lacrimal para RT-qPCR: aleatoriamente, um olho com a tira filtro do teste de Schirmer e, o olho contralateral, com citologia (swab) conjuntival no fórnice inferior. Todos os indivíduos foram submetidos à biomicroscopia com lâmpada de fenda. Resultados: Dos 152 pacientes, 86 (56,6%) tiveram a COVID-19 confirmada por PCR de nasofaringe. Ambas as técnicas de coleta detectaram partículas virais: o teste de Schirmer foi positivo em 16,3% (14/86) e a citologia conjuntival em 17,4% (15/86), sem diferenças estatisticamente significativas. Não houve testes oculares positivos entre aqueles com reação em cadeia da polimerase de nasofaringe negativo. A concordância geral dos testes oculares foi de 92,7% e, em combinação, a sensibilidade aumentaria para 23,2%. Os valores médios do limiar de ciclo nos testes de nasofaringe, Schirmer e citologia conjuntival foram 18,2 ± 5,3, 35,6 ± 1,4 e 36,4 ± 3,9, respectivamente. Conclusão: Os testes de Schirmer (16,3%) e swab conjuntival (17,4%) foram igualmente capazes de detectar RNA de SARS-CoV-2 na superfície ocular por RT-PCR e demonstraram sensibilidade e especificidade indistintas. A coleta simultânea de amostras ao processamento dos testes de RT-PCR de nasofaringe, Schirmer e citologia (swab) conjuntival demonstraram carga viral significativamente menor em ambas as abordagens da superfície ocular em comparação com o teste de nasofaringe. As manifestações oculares detectadas pela biomicroscopia com lâmpada de fenda não foram claramente associadas à positividade do RT-PCR ocular.

ABSTRACT Purpose: To estimate the prevalence and risk factors of dry eye disease symptoms and clinical diagnoses in Sao Paulo city, state of Sao Paulo, Brazil. Methods: A total of 582 participants over 18 years old, living in the east zone of Sao Paulo city responded to a short questionnaire. Dry eye disease was on that is defined by the presence of severe symptoms or previous clinical diagnosis of dry eye disease by an ophthalmologist. The association between dry eye disease and possible risk factors was assessed. Results: Overall dry eye disease severe symptoms and/or clinical diagnoses prevalence was calculated as 24.4% for both sexes. Women presented a higher frequency of severe symptoms of dry eye disease (16.07%) than men (8.48%; p=0.0244), as well as the composite of severe symptoms or diagnosed dry eye disease, presented by 26.86% of women and 18.18% of men (p=0.0366). In women, ages between 55 to 75 years old were associated with dry eye disease severe symptoms (OR=3.11; 95%CI 1.56-6.23, p=0.001) and diagnosed dry eye disease (OR=2.02; 95% CI 1.04-3.93, p=0.037). Hypertension was significantly associated with dry eye disease symptoms (OR=1.98; 95% CI 1.14-3.43, p=0.015) and diagnoses (OR=3.54; 95% CI 1.92-6.53, p=0.0001) in women. Eye drops use was associated with severe symptoms of dry eye disease and diagnosed dry eye disease in both women and men (p≤0.01). Conclusions: Dry eye disease prevalence in Sao Paulo city is higher in women than in men. Age and hypertension were stronger risk factors of dry eye disease for women, while eye drops use was a significant indicator of dry eye disease for both sexes.
RESUMO Objetivo Estimar a prevalência e os fatores de risco para os sintomas e o diagnóstico clínico da doença do olho seco na cidade de São Paulo, estado de São Paulo, Brasil. Métodos: Quinhentos e oitenta e dois participantes acima de 18 anos, residentes na zona leste da cidade de São Paulo responderam a um questionário de três perguntas sobre olho seco. A doença do olho seco foi definida pela presença de sintomas severos ou diagnóstico clínico prévio de doença do olho seco por um oftalmologista. A associação entre doença do olho seco e possíveis fatores de risco foi avaliada. Resultados: A prevalência de sintomas graves da doença do olho seco e/ou diagnóstico clínico foi calculada em 24,4% para ambos os sexos. O sexo feminino apresentou uma frequência maior de sintomas severos da doença do olho seco (16,07%) que o sexo masculino (8,48%; p=0,0244), assim como a associação de sintomas severos ou diagnóstico de doença do olho seco, foi de 26,86% no sexo feminino e 18,18% no sexo masculino (p=0,0366). No sexo feminino, a faixa etária entre 55 e 75 anos de idade foi associada com sintomas severos da DOS (odds ratios (OR) = 3,11; IC 95% 1,56-6,23; p=0,001) e com doença do olho seco diagnosticada (OR=2,02; IC 95% 1,04-3,93; p=0,037). Hipertensão foi associado com sintomas da doença do olho seco (OR=1,98; IC 95% 1,14-3,43; p=0,015) e diagnóstico da doença do olho seco (OR=3,54; IC 95% 1,92-6,53; p=0,001) no sexo feminino. Uso de colírios foi associado a sintomas severos e diagnóstico da doença do olho seco em ambos os sexos (p≤0,01). Conclusão: A prevalência da doença do olho seco na cidade de São Paulo é mais frequente no sexo feminino que no masculino. Idade e hipertensão foram fatores de risco maiores para doença do olho seco no sexo feminino, enquanto uso de colírios foi um indicador de doença do olho seco para ambos os sexos.

Individuals with suspected COVID-19 symptoms (n=202) were tested using nasopharyngeal RT-qPCR. All individuals underwent corneal esthesiometry measurements using the Cochet-Bonnet esthesiometer during their first visit; 50 participants underwent an additional measurement at a mean interval of 32.5 (17.8) days. COVID-19 was confirmed in 101 subjects (50%) using nasopharyngeal PCR. The mean time from symptom onset to disease diagnosis and corneal esthesiometry was 4.2 (2.1) days. Mean corneal esthesiometry findings based on the positive and negative PCR status indicated no statistical difference. This study demonstrated that COVID-19 had no effect on corneal esthesiometry in individuals with acute-phase COVID-19.

BACKGROUND/AIMS: We analysed the ability of B-scan ultrasound, ocular electrophysiology testing and videoendoscopic examination for predicting visual prognosis in Boston Type 1 keratoprosthesis (KPro-1) candidates. Indirect anatomical and electrophysiological findings and results from direct endoscopic evaluations were correlated with postoperative functional data. METHODS: In this prospective and interventional study, we included 13 individuals who had previously been indicated for Kpro-1 surgery. All subjects underwent preoperative screening, including ophthalmic evaluation, B-scan ultrasound, electrophysiological testing, and perioperative intraocular videoendoscopic evaluation (VE). B-scan ultrasound, electrophysiological testing, and VE evaluation results were categorised as favourable or unfavourable predictors of postoperative functional results according to predefined criteria. The predictability values of B-scan ultrasound, electrophysiological testing, and VE prognostication were calculated based on the visual acuity level achieved. RESULTS: All surgeries and perioperative VEs were uneventful. Preoperative best-corrected visual acuity (BCVA) ranged from light perception to counting fingers. The 1-year postoperative BCVA was better than 20/200 (satisfactory visual acuity result) in 10 eyes (76.9%) and 20/40 or better in 5 eyes (38.5%). B-scan ultrasound presented a positive predictive value (PPV) of 85.7% for satisfactory postoperative visual acuity, electroretinography showed a PPV of 66.7%, and visual evoked potential presented a PPV of 66.7%. The perioperative VE PPV of a negative finding for satisfactory visual acuity was 100%. CONCLUSIONS: Fundoscopic visualisation by intraocular VE is a minimally invasive procedure that can be used to predict functional outcomes in keratoprosthesis candidates. This technique demonstrated better prognostication in keratoprosthesis candidates than B-scan ultrasound and electrophysiological testing.

We reported a case of upper eyelid necrosis initially misdiagnosed as a preseptal cellulitis following a hordeolum externum resulting in great damage to the upper eyelid (anterior lamella). The infection was successfully treated with surgical cleansing, drainage, and endovenous antibiotics. Early treatment may avoid severe complications such as eyelid deformity, systemic involvement, and blindness.

PURPOSE: To compare the severity and laterality of keratoconus according to allergic rhinitis, scratching and sleeping habits, and manual dexterity. METHODS: Objective assessments regarding allergic rhinitis, eye itching, and slee-ping position among patients with keratoconus (diagnosed based on corneal tomography) were conducted. Diagnostic criteria and classification were based on the Amsler-Krumeich classification. RESULTS: Ocular pruritus was reported by 29 of 34 participants (85.29%). Eighteen participants (62.07%) reported equal scratching of both eyes, six (20.69%) more on the right eye, and five (17.24%) more on the left eye. Comparison of the main sleeping position and the eye with more severe presentation of the disease using Fisher's exact test revealed some correlations (0.567 and 0.568 in the right and left eye, respectively). However, these correlations were not statistically significant. CONCLUSIONS: The association between higher keratometry values and sleeping position appears to be more significant than that reported between keratometry and itching, or manual dexterity.

PURPOSE: The goal of this study was to determine the impact of a mobile eye health unit on access to eye care and to generate a profile of the population requiring ophthalmic care by age, nature of their ophthalmic diseases, and optimal management. METHODS: The study was conducted in 14 cities in the southwest region of São Paulo, Brazil. Subjects included individuals who participate in the Brazilian Unified Health System who were in need of eye care. There were no restrictions on age, gender or socioeconomic status. Data was transferred to an Excel table for statistical analyses. RESULTS: We evaluated 6,878 participants in this survey with mean age of 44 years (range 4 months to 96 years); 65.5% were female. Among the diagnoses, 78.6% presented with refractive errors, 9.6% presented with cataracts and 8.3% presented with pterygium. New corrective lenses were prescribed for 60.9% of the participants; 10% retained their existing lenses, ~28% required counseling only and18.1% of the participants were referred to a tertiary facility for specialized exams and/or surgical procedures. Of the participants who required outside referrals, 36.4% required oculoplastic/external eye surgery and 31.8% required cataract surgery. CONCLUSION: The vast majority of patients presenting to a mobile eye health unit required prescriptions for corrective lenses. The rate of detection of ocular disorders was relatively high and the mobile unit provided effective treatment of refractive errors and referrals for specialized ophthalmic examinations and procedures. A mobile eye health unit can be an effective alternative method for improving access to basic eye care, for promoting eye health education and preventing blindness.

Data was transferred to an Excel table for statistical analyses. Results: We evaluated 6,878 participants in this survey with mean age of 44 years (range 4 months to 96 years); 65.5% were female. Among the diagnoses, 78.6% presented with refractive errors, 9.6% presented with cataracts and 8.3% presented with pterygium. New corrective lenses were prescribed for 60.9% of the participants; 10% retained their existing lenses, ~28% required counseling only and18.1% of the participants were referred to a tertiary facility for specialized exams and/or surgical procedures. Of the participants who required outside referrals, 36.4% required oculoplastic/external eye surgery and 31.8% required cataract surgery. Conclusion: The vast majority of patients presenting to a mobile eye health unit required prescriptions for corrective lenses. The rate of detection of ocular disorders was relatively high and the mobile unit provided effective treatment of refractive errors and referrals for specialized ophthalmic examinations and procedures. A mobile eye health unit can be an effective alternative method for improving access to basic eye care, for promoting eye health education and preventing blindness.
RESUMO Objetivo: Determinar o impacto do uso de unidade móvel no acesso à saúde ocular e avaliar o perfil da população que necessita de cuidados oftalmológicos, as doenças oculares mais frequentes e o tratamento. Métodos: Estudo transversal realizado em 14 municípios da região sudoeste do Estado de São Paulo utilizando uma unidade móvel oftalmológica. Os participantes eram usuários do Sistema Único de Saúde que procuraram atendimento oftalmológico, sem restrição quanto a idade, gênero ou condição socioeconômica. Os dados foram transferidos para a tabela Excel para análise estatística. Resultados: Participaram do estudo 6.878 pessoas, com média de idade de 44 anos (variação de 4 meses a 96 anos) e 65,5% eram mulheres. Erros refrativos estavam presentes em 78,6% dos participantes, catarata em 9,6% e pterígio em 8,3%. Para 60% foram prescritos óculos, para 10% foi mantida a correção óptica em uso e para 28% foram necessárias apenas orientações. Exames especializados ou procedimentos cirúrgicos foram indicados para 18,1% dos casos que foram encaminhados para tratamento em serviço terciário. Dentre os pacientes referenciados, 36,4% necessitavam de cirurgia oculoplástica ou para tratar afecções externas do olho e 31,8%, de cirurgia de catarata. Conclusão: A grande maioria dos pacientes que procurou atendimento na unidade móvel necessitava de prescrição de óculos. A unidade móvel oftalmológica possui alto grau de resolutividade para os problemas oculares, com oportunidade de tratar os erros refrativos e referenciar os pacientes que necessitam de atendimento especializado, geralmente relacionado a condições cirúrgicas. Unidades móveis podem ser uma alternativa aos cuidados oftalmológicos básicos, melhorando o acesso, atuando na promoção da saúde ocular e prevenindo a cegueira.

PURPOSE: To develop a database with social, demographic and professional information of all graduates of the two post-graduate programs in Ophthalmology of EPM-UNIFESP, including their opinions on quality, application, and contribution of the courses received in their professional careers. METHODS: The survey was conducted in the digital and physical archives of the University and by telephone contact. When the graduates' e-mails were all collected, the electronic questionnaire was applied. The responses were compiled. Descriptive analysis of the results obtained in this cross-sectional study was performed, and analyzed by the authors and by statistical professionals, through Excel graphs. RESULTS: The database suggests that most graduates were born and work in the state of São Paulo. A significant fraction of 66.77% is dedicated to academic work, but only 36.2% hold management positions. Most of them receive amounts of one to 56 minimum wages monthly. The main motivation was to improve their professional careers. CONCLUSION: For post-graduate programs, a database with information of its graduates can elucidate whether the goals were achieved based on the proposed teaching, as well as can generate reflections to improve the quality, the courses expectations and the vision that students have of the University.

PURPOSE: To study the cost-effectiveness of ranibizumab and bevacizumab for the treatment of age-related macular degeneration. METHODS: We used a decision tree model to analyze the cost-effectiveness of ranibizumab and bevacizumab for the treatment of age-related macular degeneration, from the Brazilian Public Health System (SUS) perspective. Ranibizumab and bevacizumab were administered to patients with the same treatment procedure, and the difference in treatment costs was calculated based on the cost of the drugs. Direct costs were estimated using the information provided by the Brazilian SUS. Effectiveness in terms of quality-adjusted life years (QALYs) was calculated based on the utility values for visual impairment. Incremental cost-effectiveness ratio was calculated by comparing both treatments. The analytical horizon was one year. RESULTS: The decision tree analysis showed that the difference in treatment effectiveness was 0.01 QALY. Incremental cost-effectiveness ratio showed that ranibizumab treatment required an incremental annual cost of more than R$ 2 million to generate 1 additional QALY, as compared to bevacizumab. CONCLUSIONS: From the Brazilian SUS perspective, bevacizumab is more cost-effective than ranibizumab for the treatment of neovascular age-related macular degeneration. Its use could allow potential annual savings in health budget.
