ABSTRACT

Trauma ocular é causa importante de baixa de acuidade visual em todos os países do mundo. A integridade do bulbo ocular é primordial para recuperação visual nesses pacientes. Acidentes domésticos, automobilísticos, esportivos, além de queimaduras químicas e térmicas são as principais causas de trauma em nosso meio. O uso de lentes de contato é indicado para a reabilitação visual em casos de astigmatismos regulares ou irregulares de córnea, anisometropias, afacias, opacidades paracentrais superficiais ou profundas na córnea decorrentes do trauma ocular. As lentes de contato podem ser utilizadas no pós-trauma com finalidade terapêutica ou para correção visual. As lentes mais utilizadas para correção visual pós-trauma são as lentes de contato rígidas gás permeáveis, com alto coeficiente de permeabilidade. As lentes de contato gelatinosas podem ser usadas imediatamente após o trauma ocular com finalidade terapêutica e mais tardiamente para correção óptica em afacias e anisometropias traumáticas. A lente de contato é parte importante no tratamento tardio do trauma ocular, propiciando melhora significativa da acuidade visual na maioria dos casos.


Ocular trauma is an important cause of visual acuity loss worldwide. Visual recovery is related to anatomical integrity. The main causes of trauma are domestic and automobilist accidents, sports practice and chemical or thermic burns. Contact lens is indicated for visual rehabilitation in cases of corneal regular and irregular astigmatisms, anisometropic and aphakic patients and in cases of deep or superficial corneal opacities that do not affect the visual axis. Contact lens can be used in the post- trauma period for therapeutic and optical purposes. Rigid gas permeable contact lens, with a high permeability index, is the most used for optical purpose. Soft contact lens can be used immediately after trauma as therapy or later for optical correction in aphakic and anisometropic patients. In most cases contact lens is an important part of trauma treatment improving visual acuity in the majority of cases.

ABSTRACT

This study was done to document the effect of SCL on the Egyptian patients conjunctiva. One hundred patients had been followed up during the previous 2 years. The adverse conjunctival reaction known by GPC were seen in 24 cases in this study all, the wearers were used soft lens and non of the hard wearers showed this syndrome. Also extended wear SCL wearer were more prone to the development of this adverse reaction than the daily wear lenses by 4:1
