  • Abstract
  • Look Inside

We evaluated the electro-oculographical fea-tures in 34 eyes, 17 patients, with high myopia of -8.25 diopters or more. The tests included the L/D ratio, hyperosmolarity response, Diamox response and bicarbonate response. These tests were sup-posed to be concerned with the activities of retinal pigment epithelium (RPE). Diamox response was abnormal in 3 eyes with tigroid fundus only. This finding seemed to indicate widespread abnormality of RPE predisposed to chorioretinal atrophy in high myopia. The abnormal EOG tests became more frequent parallel with the severity of chorioretinal atrophic lesions. All 8 eyes with macular hemor-rhage due to neovascularization manifested abnor-mality in some of the EOG responses irrespective of atrophic lesion. The results of EOG responses in high myopia with diffuse chorioretinal atrophy were compatible with those in senile disciform macular degeneration and angioid streaks, in which the Diamox response was normal and the hyperos-molarity and bicarbonate responses were abnormal.
