Abstract:
OBJECTIVE: To investigate the manifestations and treatment principles of ocular diseases associated with human immunodeficiency virus infection (HIV) and acquired immunodeficiency syndrome (AIDS). METHODS: It was a retrospective case series. One hundred and ten patients were recruited. Two hundred and twenty eyes underwent ophthalmologic examination that included vision acuity, anterior segment and fundus examinations with papillary dilation and fundus fluorescein angiography. CD(4)(+)T-lymphocyte was counted in peripheral blood of 110 patients. Intravitreal injection of ganciclovir 400 microg was performed in 4 eyes (2 patients) with cytomegalovirus (CMV) retinitis associated with AIDS. All statistical analyses were performed using SPSS 13.0 software. The association between the age, duration of HIV infection and HIV/AIDS related ocular manifestations was analyzed by Pearson Correlation Analysis. The association between the gender and HIV/AIDS related ocular manifestations was analyzed by Pearson Chi-Square test. For comparison of the CD(4)(+)T cells counts of the patients with normal fundus, HIV retinopathy, CMV retinitis, Kruskal-Wallis Test for Several Independent Samples was used. RESULTS: Baseline visual acuity: no light perception (NLP) 5 eyes; light perception (LP) to 0.04, 10 eyes; 0.05 to 0.2, 14 eyes; 0.3 to 0.7, 62 eyes and >/= 0.8, 129 eyes. Small grayish keratin precipitates or pigment keratin precipitates were present in 25 eyes, 22 eyes had positive aqueous flare, 4 eyes had posterior synechia of the iris, 28 eyes had cataract. HIV retinopathy was present in 34 eyes. Cotton-wool spots, retinal hemorrhages, and retinal microaneurysms were found in eyes with HIV retinopathy. CMV retinitis was present in 32 eyes. The fundus manifestations of CMV retinitis included retinal vasculitis; dense, full-thickness, yellow-white lesions along vascular distribution with irregular granules at the border, and hemorrhage on the retinal surface in 26 eyes. Late stage retinopathy was demonstrated in 3 eyes characterized as atrophic retina, sclerotic and attenuated vessels, and optic nerve atrophy. Retinal detachment was found in 3 eyes. The median of CD(4)(+)T-lymphocyte counts of the patients with normal fundus was 100.0/mm(3). The median of CD(4)(+)T-lymphocyte counts of the patients with HIV retinopathy was 41.0/mm(3). The median of CD(4)(+)T-lymphocyte counts of the patients with CMV retinitis was 18.0/mm(3). The difference of CD(4)(+)T-lymphocyte counts between patients with normal fundus and HIV retinopathy was statistically significant (chi(2) = 4.848, P = 0.028). The difference of CD(4)(+)T-lymphocyte counts between patients with normal fundus and CMV retinitis was statistically significant (chi(2) = 15.696, P = 0.000). The difference of CD(4)(+)T-lymphocyte counts between patients with CMV retinitis and HIV retinopathy was statistically significant (chi(2) = 4.860, P = 0.027). Four eyes (2 patients) with CMV retinitis underwent intravitreal injection of ganciclovir 400 microg. After intravitreal injection of ganciclovir, visual acuity was improved and fundus lesions disappeared in 4 eyes. CONCLUSIONS: HIV retinopathy is a common intraocular complication in HIV-infected patients. CMV retinitis is the severest intraocular complication in patients with AIDS. Highly active anti-retroviral therapy allows immune reconstitution. Intravitreal injection of ganciclovir can effectively control CMV retinitis and save the vision.
