ABSTRACT
Objective:
To investigate the characteristics of retinal nerve fiber layer (RNFL) thickness in AIDS patients with normal fundus, HIV-related microvascular retinopathy (MVR), and cytomegalovirus retinitis (CMVR).Methods:
In this cross-sectional study, 111 patients were diagnosed with AIDS from 2012 to 2017 by infectious disease physicians in Beijing You'an Hospital. There were 105 males and 6 females, aged 20-65 years. According to the results of ophthalmic examination, the patients were divided into three groups 31 patients in the active-stage CMVR group, 47 patients in the MVR group, and 33 patients with normal fundus in the control group. RNFL thickness was measured by optical coherence tomography in all patients. At the same time, visual acuity, intraocular pressure, and fundus were examined, and AIDS-related systemic examination (CD4(+) T lymphocyte count, HAART treatment status, and blood cytomegalovirus DNA level) was performed. The measurement data were compared by t-test, variance analysis or rank sum test. The counting data were compared by chi square test or Fisher exact probability method.Results:
In the control group, the thickness of RNFL in the superior quadrant in the left and right eyes was 145 (79, 231) µm and 142 (46, 179) µm, respectively; the difference was statistically significant (Z=-2.481, P=0.013). The RNFL thickness of the diseased and healthy eyes in the MVR group was 116 (91, 138) µm and 122 (82, 192) µm, respectively, with no significant difference (Z=-0.861, P=0.389); the best corrected visual acuity was 0.0 (0.0, 0.2) and 0.0 (0.0, 0.2), respectively, with no significant difference (Z=-0.378, P=0.705). In the CMVR group, the best corrected visual acuity of the diseased and healthy eyes was (0.23±0.48) and (0.02±0.82), respectively, and the difference was statistically significant (t=-2.944, P=0.003); the RNFL thickness was 133 (61, 219) µm and 121 (69, 146), respectively, in the whole optic disc, with statistically significant difference (Z=-2.385, P=0.017), 104 (41, 374) µm and 82 (55, 121) µm, respectively, in the nasal quadrant, and 99 (14, 173) µm and 72 (36, 111) µm, respectively, in the temporal quadrant, with statistically significant difference (Z=-2.045, -2.543; P=0.041, 0.011). The RNFL thickness in the CMVR group, the MVR group, and the control group was 149 (61, 350) µm, 126 (71, 304) µm, and 113 (87, 149) µm, respectively, with statistically significant difference (H=20.908, P=0.000).Conclusions:
The fundus of AIDS patients had different characteristics on optical coherence tomography. In active CMVR patients, the thickness of RNFL was generally thickened. In MVR patients, the average thickness of RNFL was thicker than that in the normal control group.(Chin J Ophthalmol, 2020, 56258-265).Palavras-chave
