ABSTRACT Objective: To compare the clinical efficacy of two different doses of topical cyclosporine A used in addition to artificial tears in the treatment of patients with meibomian dysfunction and secondary dry eye. Methods: Fifty patients aged 18 to 40 years, who presented to our clinic between June 2020 and June 2021 were included in our study. Patients were divided into two groups as Group A (topical cyclosporine A 0.05%) and Group B (topical cyclosporine A 0.1%). All the patients […]

PURPOSE: The present work aimed to present the development of a conjunctival mucosa system for the controlled delivery of cyclosporine A (CsA) in the treatment of keratoconjunctivitis sicca (KCS). METHODS: The conjunctival mucosa system was prepared in the form of films containing chitosan as the polymer and CsA as the drug (25%w/v). The films were applied to the conjunctival sac of one eye from normal rabbits (n=6), and the evaluation of lachrymal production was performed daily, before and after application, […]

PURPOSE: This study evaluates the use of topical cyclosporine 0.05% and sodium carboxymethylcellulose 0.5% for the treatment of dry eye disease in patients infected with the human immunodeficiency virus. METHODS: Twenty HIV-positive-patients were selected from the Department of Infectious Diseases of the Federal University of Rio de Janeiro Hospital. Dry eye diagnosis was based on a dry eye questionnaire (Ocular Surface Disease Index – OSDI®), Schirmer I test, break up time and 1% rose bengal staining of the ocular surface. […]

PURPOSE: To assess the efficacy of topical cyclosporine .05% for preventing endothelial loss in cornea transplant. METHODS: Retrospective study of 18 eyes submitted to penetrating transplant due to keratoconus, operation carried out by the same surgeon. Patients with specular microscopy with lower than or equal to 1200 cells/mm2 belonged to the control group. The inclusion criterion was the occurrence of specular microscopy in the postoperative period over the 6- month, 1- year, and 2- year periods and the exclusion criterion […]
