Latent ocular deviations in patients with advanced AIDS.
The purpose of this study is to determine horizontal latent ocular deviations in patients with advanced AIDS (CD4+ count <0.050 x 10(9)/l) and to compare with normal values by means of the von Graefe technique. Twenty patients aged between 17 and 44 years with AIDS and aged-matched control groups were submitted to study. The AC/A ratio was also measured in both groups using the Gradient test. The AIDS patients showed a horizontal latent deviation value of 0.28+/-1.07delta exo at near (40 cm.) and 2.12+/-1.37delta eso at distance (6 m). The AC/A ratio obtained was 2.03+/-0.65. Statistically significant differences were obtained in relation to aged-matched control group at near and at distance (p<0.01). The horizontal latent ocular deviation at near and at distance in advanced AIDS patients showed lower values than the expected. The AC/A relationship also was lower. The results obtained in this study indicate that AIDS patients suffer a divergence insufficiency, which could add to other visual complaints such as blurred vision, photophobia, nyctalopia and reading difficulty.
