Ocular surface evaluation in patients treated with a fixed combination of prostaglandin analogues with 0.5% timolol maleate topical monotherapy: a randomized clinical trial

OBJECTIVES: To compare ocular surface changes induced via glaucoma treatment in patients using fixed combinations of prostaglandin analogues (travoprost, latanoprost and bimatoprost) with 0.5% timolol maleate METHODS: A prospective, multicenter, randomized, parallel group, single-blind clinical trial was performed in 33 patients with ocular hypertension or open angle glaucoma who had not been previously treated. The ocular surface was evaluated prior to and three months after treatment, with a daily drop instillation of one of the three medications. The main outcome measurements included the tear film break-up time, Schirmer's test, Lissamine green staining, the Ocular Surface Disease Index questionnaire, impression cytology using HE and PAS and immunocytochemistry for interleukin-6 and HLA-DR. Ensaiosclinicos.gov.br: UTN - U1111-1129-2872 RESULTS: All of the drugs induced a significant reduction in intraocular pressure. Decreases in the Schirmer's test results were observed with all of the drugs. Decreases in tear-film break-up time were noted with travoprost/timolol and latanoprost/timolol. An increase in the Lissamine green score was noted with travoprost/timolol and bimatoprost/timolol. The Ocular Surface Disease Index score increased after treatment in the travoprost/timolol group. Impression cytology revealed a significant difference in cell-to-cell contact in the same group, an increase in cellularity in all of the groups and an increase in the number of goblet cells in all of the groups. The fixed combinations induced an increase in IL-6 expression in the travoprost/timolol group, in which there was also an increase in HLA-DR expression. CONCLUSIONS: All of the fixed combinations induced a significant reduction in intraocular pressure, and the travoprost/timolol group showed increased expression of the inflammatory markers HLA-DR and interleukin-6. All three tested medications resulted in some degree of deterioration in ...

Análise dos efeitos da injeção subtenoniana posterior de triancinolona: série de casos / Effects of analysis of posterior subtenon injection of triamcinolone: a case series

OBJETIVO: Avaliar os efeitos da injeção subtenoniana posterior de acetato de triancinolona em pacientes com inflamação intra-ocular. MÉTODOS: Série de casos em que foram avaliados 24 pacientes (26 olhos) submetidos a injeção subtenoniana posterior de acetato de triancinolona para o tratamento de inflamação intra-ocular. Em todos os pacientes foi associado o maleato de timolol 0,5 por cento por 30 dias. RESULTADOS: Foi observado melhora da acuidade visual em 81 por cento dos pacientes após injeção única de acetato de triancinolona. Não foi observado aumento significativo da pressão intra-ocular em nenhum dos olhos tratados. CONCLUSÃO: O acetato de triancinolona sob a forma de injeção subtenoniana posterior mostrou ser uma forma eficaz e segura de tratamento para as inflamações intra-oculares.

PURPOSE: To evaluate the effects of posterior subtenon injection of triamcinolone acetonide in patients with intraocular inflammation. METHODS: Case series enrolling 24 patients (26 eyes) submitted to posterior subtenon injection of triamcinolone acetonide for intraocular inflammation treatment. Maleate timolol at 0.5 percent was prescribed for all patients for 30 days. RESULTS: Improvement of visual acuity was observed in 81 percent of the patients after a single injection of triamcinolone acetonide. Increase in the intraocular pression was not observed in the treated eyes. CONCLUSION: Posterior subtenon injection of triamcinolone acetonide proved to be a safe and effective way of treating intraocular inflammations.
