RESUMO
ABSTRACT This report described a case of a 56-year-old female patient with a history of pterygium excision and use of mitomycin C eye drops during the postoperative period who developed necrotizing infectious scleritis caused by Pseudomonas aeruginosa. The patient was admitted for treatment with intravenous antibiotic therapy, topical fortified antibiotics, systemic corticotherapy, and debridement of the necrotic ocular tissue. After 3 weeks, she presented with good clinical evolution and resolution of the infection. Mitomycin eye drops should be used cautiously, particularly after surgery. If mitomycin is used, it should be applied at the lowest concentration and for the shortest duration possible and should be avoided postoperatively to prevent these complications. Although scleral infection is a serious condition with a high risk of permanent vision loss, early and appropriate treatment can be critical for good clinical outcomes.
RESUMO Este relato descreve o caso de uma paciente de 56 anos com história de exérese de pterígio e uso de colírio de mitomicina C no pós-operatório, que desenvolveu esclerite infecciosa necrosante por Pseudomonas aeruginosa. A paciente foi internada para tratamento com antibioticoterapia endovenosa, antibióticos tópicos fortificados, corticoterapia sistêmica e desbridamento do tecido necrótico ocular. Após 3 semanas, apresentou boa evolução clínica e resolução da infecção. Os colírios de mitomicina devem ser usados com cautela, principalmente após a cirurgia. Se a mitomicina for usada, ela deve ser aplicada na menor concentração e pela menor duração possível, devendo ser evitada no pós-operatório, para evitar essas complicações. Embora a infecção escleral seja uma condição grave com alto risco de perda permanente da visão, o tratamento precoce e correto pode ser fundamental para bons resultados clínicos.
RESUMO
AIM: To evaluate corneal parameters measured with a dual Scheimpflug analyzer in keratoconus patients implanted with intrastromal corneal ring segments (ICRS). METHODS: Fifty eyes of 40 keratoconus patients had Ferrara ICRS implantation from November 2010 to April 2014. Uncorrected visual acuity (UCVA), best corrected visual acuity (BCVA), refraction, keratometry, asphericity, elevation, pachymetry, root mean square (RMS), spherical aberration and coma were studied. All patients were evaluated using a dual Scheimpflug system. RESULTS: The mean follow-up time after the procedure was 12.7mo. The mean UCVA improved from 0.82 to 0.31 (P<0.001); the mean BCVA improved from 0.42 to 0.05 (P<0.0001), the mean spherical refraction changed from -3.06±3.80 D to -0.80±2.5 D (P<0.0001) and the mean refraction astigmatism reduced from -4.51±2.08 D to -2.26±1.18 D (P<0.0001). The changes from preoperative to postoperative, in parameters of the anterior and posterior surface of the cornea, were statistically significant except the elevation posterior at the apex of the cornea and posterior asphericity. CONCLUSION: The implantation of Ferrara ICRS induces changes in both anterior and posterior surfaces of the cornea.
