ABSTRACT Objective To describe and validate an ophthalmic model for corneal transplantation and micro suture training using a bovine eyeball as a model. Methods For the training model, the eyeball was placed under the sanitary field placed on the ends of a common 3.5cm diameter cylindrical plastic container for corneal removal. A superficial circular incision was made, then 9cm curved Castroviejo scissors were used for complete corneal removal. The cornea was replaced in its original position, and 10-0 nylon thread […]

ABSTRACT Amyloidosis is characterized by extracellular deposition of protein amyloid fibrils in tissues, including conjunctiva, which are insoluble in proteolytic proteins. Conjunctival amyloidosis specifically in the palpebral conjunctiva is a rare finding in clinical practice. The authors described the case of a 71-year-old caucasian male patient, with bilateral lesions located in the lower eyelid conjunctiva, elevated, well-defined, yellowish, combined with destabilized eyelids. Surgical excision of the lesions was performed, and the histological examination confirmed conjunctival amyloidosis. There was no recurrence […]

Objective: The objective of the present study was to develop a methodology that approximates the student of the content addressed in the classes of anatomy of the eyeball. Methods: A circular incision was made in the orbital blade of the frontal bone of a human cadaver of a health institution and, to access the orbital structures, the area structures were dissected creating a pathway for the injection of a solution of white silicone rubber between the lens and the retina […]

Methods: It was performed a observational, analytic, cross-sectional study. The group of patients enrolled 24 individuals (13 females and 11 males), aged from 27 to 73 years (55.7±11.6 years). In the control group were included 22 subjects (12 females and 10 males) aged from 31 to 77 years (55.4±16.5 years). Of the 92 eyes evaluated, three were excluded because they […]

Objetivo: Avaliar os resultados pós-operatórios da utilização da LIO tórica durante a facoemulsificação. Métodos: Estudo retrospectivo tipo coorte de 95 olhos de 67 pacientes, selecionados através de censo. Foram analisados pacientes com catarata, submetidos à facoemulsificação, com colocação da LIO tórica Acrysof®, no período de janeiro de 2010 a dezembro de 2012. No entanto, foram excluídos os que realizaram outro tipo de cirurgia ou tiveram outro tipo de lente para correção da catarata e/ou prontuários incompletos. Considerou-se como sucesso o […]

Purpose: To evaluate the postoperative results when using the toric IOL during phacoemulsification. Methods: Retrospective cohort based study on the 95 eyes of 67 patients, selected by a census. Analyzed patients with cataracts who had undergone phacoemulsification placement with AcrySof® toric IOL from january 2010 to december 2012. For analysis purposes, it was considered successful when the residual astigmatism was d”0.75 diopters. The Wilcoxon test for related samples was used to compare non-parametric samples, while the Student T test was […]
