获得性免疫缺陷综合征并发巨细胞病毒性视网膜炎的临床分析

目的探讨获得性免疫缺陷综合征(acquiredimmunodeficiencysyndrome,AIDS)并发巨细胞病毒(cytomegalovirus,CMV)性视网膜炎的眼底表现特点、全身症状及治疗预后。方法观察8例(15只眼)AIDS并发CMV性视网膜炎的临床表现,分析其眼底、视力、荧光素眼底血管造影及CD4+T淋巴细胞检测结果,并对其中2例(4只眼)行更昔洛韦玻璃体腔注药治疗。随访时间2～34个月,平均16个月。结果初诊视力≤0.2者10只眼(66.7%),其中无光感者2只眼,眼前光感者2只眼,0.04～0.20者6只眼;0.8和0.9者各1只眼(13.3%);≥1.0者3只眼(20.0%)。12只眼的眼底表现为视网膜血管炎特点,呈沿血管分布的浓厚黄白色病损,其上有片状出血,边缘为不规则的黄白色颗粒,可形象描述为“奶酪加番茄酱样视网膜炎”;玻璃体透明或反应轻微。2只眼的眼底呈晚期表现,视网膜萎缩呈灰色,视网膜血管硬化、狭窄,视网膜色素上皮萎缩,可透见脉络膜血管及视神经萎缩。1只眼视网膜脱离。8例患者的CD4+T淋巴细胞计数在0～36个/mm3之间,平均(15.0±12.9)个/mm3。4只眼玻璃体注药后视力均显著提高。眼底病变明显消退,出血吸收。结论CMV性视网膜炎是AIDS最常见、最严重的眼部并发症。眼底表现特点为进行性、坏死性视网膜炎伴出血,同时合并有视网膜血管炎。但玻璃体反应无或轻微。对原因不明的黄白色病损、视网膜出血及视网膜血管炎应行血清人类免疫缺陷病毒(humanimmunodeficiencyvirus,HIV)抗体检测。反之,HIV阳性者应常规进行眼底检查。(中华眼科杂志,2005,41:803806)

Cytomegalovirus retinitis associated with Acquired immunodeficiency syndrome

OBJECTIVE: To investigate the fundus characteristics, systemic features and therapeutic outcomes of cytomegalovirus (CMV) retinitis associated with acquired immunodeficiency syndrome (AIDS). METHODS: Fundus features, visual acuity, fundus fluorescence angiography (FFA) and CD4(+)T-lymphocyte counts of 15 eyes (8 patients) of CMV retinitis associated with AIDS were analyzed. The time of average follow-up was 16 months. Intravitreal injection of ganciclovir (400 microg) was performed in 4 eyes (2 patients). RESULTS: In the initial examination, visual acuity of the patients was as following: < or = 0.2, 10 eyes (66.7%); no light perception (NLP) (2 eyes); light perception (LP) (2 eyes); 0.04-0.2, 6 eyes; > or = 1.0, 3 eyes (20.0%) and 0.8 or 0.9 each for 1 eye (13.3%). The fundus manifestation includes: the retinal vasculitis; dense, full-thickness, yellow-white lesions along vascular distribution, and hemorrhage on the retinal surface; granular with irregular border featured as "cheese and ketchup retinitis" was revealed in 12 eyes; the vitreous was clear or light opaque. Late stage of the retinopathy was demonstrated in 2 eyes characterized as grayish atrophic retina, vessel-sclerotic and attenuated, retinal pigment epithelium (RPE) atrophy, prominent choroid vasculature, and optic nerve atrophy. Retinal detachment was found in 1 eye. CD4(+)T-lymphocytes counts in peripheral blood were between 0 approximately 36/mm(3), average (15.0 +/- 12.9) mm(3). Visual acuity improved, fundus lesions disappeared observably and hemorrhage was absorbed in the 4 eyes after intravitreal injection of ganciclovir. CONCLUSIONS: CMV retinitis is the severest and the most common intraocular complication in patients with AIDS. For the patients with yellow-white retinal lesions, hemorrhage and retinal vasculitis of undefined cause, the antibody of serum anti-human immunodeficiency virus (HIV) should be screened. Routing eye examination should be performed if the serological test of HIV is positive.
