Objective: To evaluate acute eye irritation in rabbits following topical administration of essential oil. Methods: animals were divided into three groups, each containing three rabbits, with a total of 6 eyes per group. The difference between them was the concentration used (1, 3 and 9%). A single dose of 0.1 ml of the product was applied into the conjunctival sac of one eye of the animal, and the contralateral eye was used as control. The effects caused by the essential […]

Objective: This study was carried out in order to assess the epidemiological profile of symptomatic dry eye in diabetic patients. Methods: Two hundred and twenty-one diabetic patients were evaluated using a specific questionnaire about other diseases and drugs. Of these, 58 who classified as having moderate to severe dry eye were included. Results: In this study, 58 of the 221 diabetic patients had moderate to severe dry eye (26.2%). Of the 58 patients, dry eye was more prevalent at age […]

Objetivo: O estudo foi realizado para descrever o perfil epidemiológico de pacientes diabéticos com olho seco sintomático. Métodos: Duzentos e vinte e um pacientes diabéticos foram avaliados por meio de questionário específico sobre outras doenças e medicamentos. Destes, 58 foram diagnosticados com olho seco moderado a severo e foram incluídos no estudo. Resultados: Neste estudo, 58 dos 221 pacientes diabéticos tinham olho seco moderado a severo (26,2%). Dos 58 pacientes, o olho seco, foi mais prevalente na faixa etária de […]

Background: Systematization of characteristics and morphological changes in the retina, and understanding its role in occlusive diseases involving retinal vessels can contribute to research on the dynamic of the pathological process and to improved understanding of disease treatment. Objective: To research the basic morphometric and structural indicators of the macular region of the retina in patients with central retinal vein occlusion (CRVO). Settings and Design: Ufa Eye Research Institute, retrospective case series. Methods: The basic morphometric and structural indices of […]

Introdução: Sistematização característica e alterações morfológicas na retina, compreensão de sua arquitetura em doenças oclusivas de vasos retinianos para contribuir com a melhoria dos estudos sobre as regularidades da dinâmica do processo patológico, diagnóstico e tratamento da doença. Objetivo: Investigar a morfometria de base e indicadores estruturais da região macular da retina em pacientes com oclusão da veia central da retina (CRVO). Definições e design: Ufa Eye Research Institute, série de casos retrospectiva. Métodos: A análise morfométrica de base e […]

Objective: The objective of this study was to evaluate the efficacy of intravitreal triamcinolone and retrobulbar chlorpromazine as alternatives in the management of ocular pain in blind eyes. Methods: This was a non-randomized interventional prospective study of patients with painful blind eye unresponsive to topical treatment and without indication of evisceration treated at the Hospital Governador Celso Ramos Ophthalmology Service in 2010. After ocular examination and ocular B mode ultrasound, patients were divided into two groups. Group 1 patients had […]

The authors describe two cases of fungal keratitis which, upon histopathological examination, are found to have in common the absence of epithelium, without ulceration and the lack of integrity of the Bowman’s layer with the presence of fungal forms in their interior. Through them the authors suggest probable mechanisms of recurrence of fungal keratitis, highlighting the possible existence of an “unusual external route” that would occur by the fungus penetration through the full Bowman layer. Although these findings appear not […]

This article presents a case of tick infestation of the lower eyelid by a previously unreported species. A 71-year-old male presented with a tick attached to the lower eyelid. The tick was identified morphologically, and then molecularly via polymerase chain reaction (PCR) and sequencing of its DNA. In addition, a review of the literature relevant to the genera of ticks associated with infestation of the human eye is provided. The tick, which was in the nymphal developmental stage, was first […]
