Correlação entre Espessura Macular e Camada de Fibras Nervosas Peripapilar no Glaucoma Inicial

Abstract

Introdução: Os autores pretendem analisar a espessura macular e a camada de fibras nervosas peripapilar (CFN) em doentes com glaucoma inicial e com o diagnóstico de hipertensão ocular (HTO). Também propõem um modelo de correspondência da espessura macular de uma dada região do hemisfério superior com a CFN temporal superior (TS) e do hemisfério inferior com a CFN temporal inferior (TI) no glaucoma inicial. Material e Métodos: Estudo retrospectivo não randomizado, constituído por 48 olhos com glaucoma inicial e 39 olhos com diagnóstico de HTO, submetidos a análise da assimetria da espessura macular do polo posterior e da CFN por Tomografia de coerência óptica Spectral Domain (SD-OCT). Avaliamos a correlação entre a espessura macular de uma região selecionada do hemisfério superior e do inferior, com a CFN TS e TI, respectivamente. Resultados: Nos doentes com glaucoma inicial, a espessura macular e a CFN (global e sectorial) foram significativamente inferiores (p<0,01). A correlação da CFN TS com a espessura macular da região selecionada do hemisfério superior foi moderada (R:0,403; p<0,01), e da CFN TI com a região selecionada do hemisfério inferior foi positiva forte (R:0,612; p<0,001). Conclusão: Dado que, a CFN TI é o sector apontado como precocemente afectado no glaucoma, e se verificou uma correlação forte com a região macular inferior selecionada, consideramos que esta também pode ser mais vulnerável à lesão glaucomatosa inicial. A avaliação desta região isoladamente ou integrada com a CFN, poderá ser valiosa no diagnóstico precoce.
