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.
RESUMEN
This study aims to compare meibomian gland (MG) dropout and MG dysfunction (MGD) between patients with diabetes mellitus (DM) with moderate-severe non-proliferative diabetic retinopathy (NPDR) and patients with no diabetes (NDM). This prospective, transversal, age, and gender-matched case-control study included 98 DM and 106 NDM eyes. Dry eye disease (DED) and MGD evaluations were performed, including meibography (Keratograph 5M®). The objective MG dropout percentage was obtained by analyzing meibography images with ImageJ software (v. 1.52o, National Institutes of Health, Bethesda, MD, USA) and was subsequently graded with Arita's meiboscore. The DM duration was 18 ± 9 years. The mean meiboscore (3.8 ± 0.8 vs. 3.4 ± 1.0, p = 0.001), meiboscore severity (p = 0.016), and MG dropout (45.1 ± 0.1% vs. 39.0 ± 0.4%, p < 0.001) were greater in DM than in NDM. All patients showed MG dropout (meiboscore > 1). Lower eyelids showed greater MG dropout in both groups. A correlation with age (r = 0.178, p = 0.014) and no correlations with DM duration or gender (p > 0.005) were observed. Patients with diabetes showed greater corneal staining (1.7 ± 1.3 vs. 0.9 ± 1.1; p < 0.001), reduced corneal sensitivity (5.4 ± 1.1 vs. 5.9 ± 0.4; p < 0.001), lower MG expressibility (3. 9 ± 1.6 vs. 4.4 ± 2.1; p = 0.017), and worse meibum quality (1.9 ± 0.8 vs. 1.7 ± 0.5; p = 0.019). Tear breakup time, osmolarity, MMP-9, Schirmer, and the Ocular Surface Disease Index showed no significant differences. In conclusion, patients with DM with NPDR have greater MG dropout and meiboscore, as well as more severe MGD and DED parameters than persons with NDM.
RESUMEN
AIM: To compare the safety and effectiveness of eyelid treatment with the ILux®-MGD Treatment System in one session versus five sessions of mechanical meibomian gland expression (MMGE) in patients with moderate to severe meibomian gland dysfunction (MGD). METHODS: A prospective, randomized, open-label, and controlled clinical trial that compared one session of the ILux® MGD Treatment System versus five sessions of MMGE in both eyes of 130 patients aged ≥18y with Ocular Surface Disease Index (OSDI) scores ≥13, total meibomian gland scores (MGS) of <15 in the lower eyelid of each eye, and non-invasive tear break-up time (NI-TBUT) <10s, who were randomized 1:1 to ILux® or MMGE. RESULTS: The mean age was 58±17.49y. Baseline total MGS scores in both treatment groups were comparable. During follow-up, there were significant differences in total MGS and per sector with P<0.001. Multivariate analysis was performed using generalized estimating equations corresponding to the generalized linear model for repeated means to determine the treatment relationship with total MGS, NIBUT, and OSDI. There was a significant difference between ILux® and MMGE (P<0.001) at follow-up from the first to the twelfth month in MGS, NI-BUT, and OSDI scores. No adverse events were reported. CONCLUSION: ILux® treatment compared to MMGE significantly improves symptoms and signs in patients with moderate to severe MGD for one year without adverse events.
RESUMEN
ABSTRACT Purpose: To compare ocular surface parameters in rosacea patients with those of controls. Methods: Ninety-three participants took part in this cross-sectional, observational, non-interventional study. These consisted of a rosacea group (n=40) and a control group (n=53). We compared objective parameters of the ocular surface, including conjunctival hyperemia, tear film stability and volume, meibomian gland dysfunction, dry eye disease, and ocular surface staining, between the two groups. Results: In the rosacea group, 69.23% were female. The mean age was 47.34 ± 12.62 years old. No statistically significant differences between groups were found in visual acuity (p=0.987), tear film parameters (tear meniscus height (p=0.338), noninvasive tear film rupture time (p=0.228), invasive rupture time (p=0.471), Schirmer's test scores (p=0.244), conjunctival hyperemia (p=0.106), and fluorescein staining (p=0.489). Significant differences were found in meibography evaluations (p=0.026), mucous layer integrity (p=0.015), and ocular surface symptoms (p<0.0001). Rosacea patients also showed important eyelid differences in glandular expressibility (p<0.001), glandular secretion pattern (p<0.001), and telangiectasia (p<0.001) compared to controls. Conclusion: Meibomian gland dysfunction is frequently associated with dermatological conditions. It can be observed in morphological findings from meibography as well as lipid secretion impairment, leading to evaporative dry eye, ocular surface dysfunction, and inflammation.
RESUMO Objetivo: Avaliar as alterações da superfície ocular em pacientes com Rosácea, e comparar com grupo controle. Métodos: Noventa e três indivíduos foram selecionados para este estudo transversal, observacional e não intervencionista, dividido em dois grupos: rosácea (n=40) e controles (n=53). Foram avaliados parâmetros objetivos da superfície ocular (hiperemia conjuntival, estabilidade e volume do filme lacrimal, disfunção da glândula meibomiana, doença do olho seco, coloração da superfície ocular) e comparado indivíduos saudáveis com pacientes com rosácea. Resultados: 69,23% dos indivíduos com rosácea eram mulheres, com média de idade de 47,34 ± 12,62 anos. Em comparação com controles pareados, não foram evidenciadas diferenças estatisticamente significativas em relação à acuidade visual (p=0,987) e parâmetros do filme lacrimal (altura do menisco lacrimal (p=0,338), tempo de ruptura do filme lacrimal não invasivo (p=0,228), tempo invasivo de ruptura (p=0,471) e teste de Schirmer (p=0,244), bem como hiperemia conjuntival (p=0,106) e coloração com fluoresceína (p=0,489). Associação significativa foi encontrada na avaliação da meibografia (p=0,026), integridade da camada mucosa (p=0,015) e sintomas de superfície ocular (p<0,0001). Pacientes com rosácea também apresentaram alterações importantes na borda palpebral: expressibilidade glandular (p<0,001), padrão de secreção glandular (p<0,001) e telangiectasia (p<0,001). Conclusão: A disfunção da glândula de Meibômio está frequentemente associada a condições dermatológicas e é caracterizada por achados morfológicos na meibografia, bem como comprometimento da secreção lipídica que leva ao olho seco evaporativo e alterações da superfície ocular e inflamação.
RESUMEN
ABSTRACT Purpose: The study aimed to evaluate the ocular surface and meibomian gland morphology in electronic cigarette (e-cigarette) smokers. Methods: The upper and lower eyelids of 25 male e-cigarette smokers and 25 healthy male non-smoker patients were evaluated using Sirius meibography. Meibomian glands loss was automatically calculated using Phoenix meibography imaging software module, with the result obtained as percentage loss. Ocular Surface Disease Index (OSDI) questionnaire, tear breakup time test, and Schirmer II test were administered and performed in all cases. Results: The mean e-cigarette smoking duration was 4.9 ± 0.9 (range, 3.4-7) years. While the mean Schirmer II test value was 9.16 ± 2.09 mm in e-cigarette group, it was 11.20 ± 2.14 mm in control group (p=0.003). Mean tear breakup time was 6.96 ± 2.31 seconds in e-cigarette group and 9.84 ± 2.13 seconds in control group (p=0.002). The mean OSDI value was 28.60 ± 6.54 and 15.16 ± 7.23 in e-cigarette and control groups, respectively (p<0.001). In Sirius meibography, the average loss for the upper eyelid was 23.08% ± 6.55% in e-cigarette group and 17.60% ± 4.94% in control group (p=0.002), and the average loss for the lower eyelid was 27.84% ± 5.98% and 18.44% ± 5.91%, respectively (p<0.001). Additionally, a significant positive correlation was identified between the loss rates for both upper and lower eyelid meibography with e-cigarette smoking duration (r=0.348, p<0.013 and r=0.550, p<0.001, respectively). Conclusion: Long-term e-cigarette smoking causes damage to the meibomian glands; therefore, meibomian gland damage should be considered in ocular surface disorders due to e-cigarette smoking.
RESUMO Objetivo: Avaliar a superfície ocular e a morfologia da glândula meibomiana em usuários de cigarros eletrônicos. Métodos: Foram avaliadas através de meibografia Sirius as pálpebras superiores e inferiores de 25 usuários de cigarros eletrônicos do sexo masculino e 25 pacientes não usuários saudáveis, também do sexo masculino. A perda nas glândulas meibomianas foi calculada automaticamente com o módulo de software de imagem de meibografia Phoenix. O resultado foi obtido como perda percentual. O questionário Ocular Surface Disease Index (OSDI), o teste do tempo de ruptura lacrimal e o teste de Schirmer II foram administrados em todos os casos. Resultados: A duração média do uso de cigarros eletrônicos foi de 4,9 ± 0,9 anos (intervalo de 3,4-7 anos). O valor médio do teste de Schirmer II foi de 9,16 ± 2,09 mm no grupo de usuários de cigarros eletrônicos e de 11,20 ± 2,14 mm no grupo controle (p=0,003). O valor médio do teste do tempo de ruptura lacrimal foi de 6,96 ± 2,31 segundos no grupo de usuários de cigarros eletrônicos e 9,84 ± 2,13 segundos no grupo controle (p=0,002). O valor médio do Ocular Surface Disease Index foi de 28,60 ± 6,54 e 15,16 ± 7,23 para os grupos de usuários de cigarros eletrônicos e controle, respectivamente (p<0,001). Na meibografia de Sirius, a perda média para a pálpebra superior foi de 23,08 ± 6,55% para o grupo de usuários de cigarros eletrônicos e 17,60 ± 4,94% para o grupo controle (p=0,002), e a perda média para a pálpebra inferior foi de 27,84 ± 5,98% e 18,44 ± 5,91%, respectivamente (p<0,001). Além disso, foi observada uma correlação positiva significativa entre a taxa de perda na meibografia palpebral superior e inferior com a duração do tabagismo eletrônico, respectivamente de (r=0,348, p<0,013) e (r=0,550, p<0,001). Conclusão: O uso prolongado de cigarros eletrônicos causa danos às glândulas meibomianas. Portanto, esses danos devem ser considerados em distúrbios da superfície ocular devidos ao uso desses dispositivos.
RESUMEN
ABSTRACT The objective of this report is to describe a case of meibomian gland dysfunction associated with keratoconus and to examine the importance of treatment for evaporative dry eye in cases of corneal ectasia. A 45-year-old man diagnosed as having keratoconus complained of burning, tearing, itching, and red eye. He had a history of penetrating corneal transplantation and wearing rigid contact lenses. The meibography revealed a severe meibomian gland dropout and normal tear meniscus height in both eyes. Objective propaedeutic tests are important tools for dry eye diagnosis and proper evaluation of ocular surface and tear film. In older patients, the classic signs of atopic conjunctivitis are not always present, and the causes of chronic rubbing must be further investigated. Treatment of underlying chronic inflammation such as dry eye, meibomian gland dysfunction, and blepharitis might be important to prevent keratoconus progression and guarantee symptom relief.
RESUMO O objetivo é relatar um caso de associação entre disfunção de glândulas de meibomius (DGM) e ceratocone, assim como ressaltar a importância do tratamento do olho seco evaporativo em casos de ectasia corneana. Paciente do sexo masculino de 45 anos com ceratocone e queixas de ardência, lacrimejamento, prurido e olho vermelho. O mesmo tem histórico de transplante de córnea penetrante e uso de lentes de contato rígidas. A meibografia revelou severa perda de glândulas de meibomius e menisco lacrimal normal em ambos os olhos. Testes propedêuticos objetivos são importantes ferramentas para diagnóstico de olho seco e apropriada avaliação da superfície ocular e filme lacrimal. Em pacientes mais velhos, os sinais clássicos de atopia não estão sempre presentes e investigações adicionais das causas de prurido crônico são necessárias. O tratamento da inflamação crônica subjacente como olho seco, disfunção de glândulas de meibomius e blefarite podem ser importantes para prevenir a progressão do ceratocone e garantir alívio dos sintomas.
RESUMEN
Abstract Background: Previous studies has shown that dry eye test abnormalities, meibomian gland dysfunction (MGD), may occur in psoriasis. Objectives: The authors aimed to evaluate the dry eye disease (DED), MGD, in psoriasis patients with meibography which is a current, objective, noninvasive method for patients with meibomian gland diseases, to investigate the relationship between disease severity and ocular involvement. Methods: This study included 50 participants with psoriasis and 50 healthy individuals. All subjects were examined by the same dermatologist and referred for ophthalmological examination including meibomian gland obstruction, lid margin alterations assessment, ocular surface disease index assessment, tear film break-up time test, Schirmer test, corneal conjunctival fluorescein staining assessment. Additionally, upper and lower lids were evaluated for meibomian gland loss with meibography. Results: MGD (28%), meibomian gland loss (MGL) (29.5%), upper meiboscore (0.61 ± 0.81), lower meiboscore (0.46 ± 0.61), DED (22%) were significantly higher in the psoriasis group compared with the control group (p = 0.008, p < 0.001, p = 0.027, p = 0.041, p = 0.044, respectively). There was a significant relationship between MGD and psoriasis area severity index (PASI) (p = 0.015, Odds Ratio = 1.211). There was a significant positive relationship between MGL with PASI (p < 0.001, r = 608) and psoriasis duration (p < 0.001, r = 0.547). Study limitations: Smaller study group and inability to detect quality changes of meibum with meibography were limitations of the study. Conclusions: Psoriasis may affect the meibomian gland morphology, may cause structural changes in meibomian glands, and as a result of these may cause MGD and DED. Therefore, ophthalmologists and dermatologists should be aware of this situation and co-evaluate the patients in this respect.

Due to the prevalence of acne vulgaris, isotretinoin is one of the most prescribed drugs among physicians and dermatologists. Although exhibiting an adequate safety profile, adverse events secondary to isotretinoin use are common. Before prescribing isotretinoin, physicians usually inquire about pregnancy and perform serologic tests including cholesterol, triglycerides, and liver enzymes. Ocular manifestations are commonly neglected. Despite being generally mild, ocular manifestations related to either topical or systemic isotretinoin may cause important ocular morbidity. The ocular surface is the most affected site within the eye; however, retinal and optic nerve disease also have been documented. Evaporative dry eye disease, which may range from mild to severe, is the most common adverse ocular effect associated with isotretinoin use. The aim of this review is to present an up-to-date overview for the dermatologist about the prevention, diagnosis, and treatment of the ocular side effects of isotretinoin, and when to refer to the eye specialist.

PURPOSE: This prospective, randomized, double-blind interventional case series was designed to evaluate the short-term efficacy of 0.03% tacrolimus ointment as a new therapeutic approach for refractory cases of posterior blepharitis. METHODS: Forty eyes (20 patients) with posterior blepharitis refractory to previous treatment were randomized. Eighteen eyes (9 patients) were treated with 0.03% tacrolimus ointment and 20 eyes (10 patients) with placebo ointment twice daily. Patients were evaluated with a questionnaire and slit-lamp examination 14 days and 28 days after treatment, and symptoms and signs of blepharitis were compared to those observed at baseline. RESULTS: We could observe statistical difference in the outcome measurements of meibomian gland secretion, conjunctival hyperemia, telangiectasia of inferior lid, Rose Bengal, and fluorescein scoring for the study group. As for the symptoms score, we observed statistical difference in the symptoms scoring for pruritus and dry eye sensation in the tacrolimus group. CONCLUSION: This study suggests that topical administration of 0.03% tacrolimus ointment can improve some symptoms and some ocular surface status in patients with refractory posterior blepharitis.

PURPOSE: The purpose of this study was to ascertain the frequency and risk factors of dry eye (DE) among patients attending a tertiary care ophthalmology center in Mexico. METHODS: Approximately 338 consecutive new patients attending a tertiary care ophthalmology center in Mexico City underwent an ocular surface examination, which included tear film break-up time, fluorescein corneal staining, Schirmer's test, and evaluation of meibum quality. Symptoms of DE were evaluated by the Ocular Surface Disease Index and Dry Eye Questionnaire-5. Information on demographics, exposures, past medical and ocular history, and medications was also collected. RESULTS: The frequency of severe DE symptoms was found to be 43% based on the Ocular Surface Disease Index and 30% based on Dry Eye Questionnaire-5. Risk factors significantly associated with increased DE symptoms included dry mouth and gastrointestinal ulcer medications. With regard to signs, aqueous tear deficiency was a less-frequent finding (22%) in our population than evaporative deficiency (94%). Risk factors associated with aqueous tear deficiency were dry mouth and diuretic use. No risk factors were associated with evaporative deficiency. Risk factors associated with meibomian gland dysfunction included old age, male sex, arthritis, and use of an antihypertensive. The only risk factor associated with corneal staining was dry mouth. CONCLUSION: This is the first study to demonstrate the frequency of symptomatic and clinical DE in a tertiary care ophthalmology center in Mexico. The frequency of DE ranged from 30% using a symptomatic definition to 94% using objective measures. Different risk factors were found for different aspects of DE, suggesting differing underlying pathophysiologies behind different DE subtypes.
