Abstract

Resumo Um traumatismo ocular contuso pode gerar uma vasta gama de lesoes intraoculares que sao dependentes da quantidade de energia que o objeto transfere ao olho durante o impacto. As lesoes da iris, malha trabecular e corpo ciliar podem repercutir na drenagem do humor aquoso. A ocorrencia de uma ciclodialise caracterizada pelo descolamento do corpo ciliar da parede escleral, criando uma comunicacao entre a câmara anterior e o espaco supracoroidiano, pode provocar importante reducao da pressao intraocular. Esta diminuicao pressorica e a responsavel pela ocorrencia da maculopatia hipotonica que pode cursar com diminuicao irreversivel da acuidade visual. Nao existe consenso na literatura sobre o tratamento das ciclodialises. Neste relato, descrevemos um caso de ciclodialise traumatica pos impacto com projetil de arma de fogo tratada com aplicacao de laser de argonio.

Highlights

The severity of blunt eye trauma is dependent on the amount of energy an object transfers to the eye at the time of contact
Tongu et al reported that the main causes of blunt eye trauma in Brazil were domestic accidents and physical aggression (32.5%), trauma during the performance of (22.5%) and occupational accidents (12.5%). [1] Balls, stones, punches, impact with airbags during car crashes and elastic cords have already been described as agents causing blunt eye trauma.[2,3,4]
The ocular globe undergoes rapid circumferential expansion, leading to various lesions ranging from subconjunctival hemorrhages, corneal abrasions or lacerations, to iris lesions, dislocation of the crystalline, traumatic cataract, vitreous hemorrhage, retinal detachment, retinal and/or choroid detachment [5]

Summary

Introduction

The severity of blunt eye trauma is dependent on the amount of energy an object transfers to the eye at the time of contact. This separation creates a communication between the anterior chamber and the supracoroid space, which may cause decreased intraocular pressure.[7] In this report we describe a case of cyclodialysis treated with argon laser photocoagulation with the aid of a gonioscopy lens.
