ABSTRACT: To evaluate the indication and clinical effects of intravitreal injection of Ganciclovir in the treatment of acute retinal necrosis (ARN). Fourteen cases (14 eyes) of ARN which were consistent with the diagnostic criteria of American Uveitis Society were enrolled. Preoperative visual acuity was: light perception, hand movement and counting fingers (CF), each in 1 eye; 0.08 - 0.1 in 4 eyes; 0.2 - 0.4 in 5 eyes 0.5 in 1 eye and 0.8 in 1 eye. Keratic precipitate and aqueous flare were presented in the anterior segment. Peripheral focal and/or patch retinal necrosis, retinal occlusive arteritis and retinal hemorrhage were observed in the fundus. Acyclovir or Ganciclovir was administrated systematically by intravenous injection. The condition of 14 eyes deteriorated underwent intravitreal injection of Ganciclovir but without retinal detachment. After intravitreal injection 2 eyes became worse and underwent vitrectomy for PVR and retinal detachment. The follow-up time varied from 4 to 74 months (mean 25 months). The inflammation of anterior segment and vitreoretinopathy of 14 cases disappeared after intravitreal injection of Ganciclovir. The visual acuity markedly increased in 12 eyes without surgical intervention. Visual acuity achieved 1.0 - 1.5 in 5 eyes, 0.5 - 0.9 in 5 eyes and 0.3 in 2 eyes after intravitreal injection of Ganciclovir. The retina of the 2 eyes undergone vitrectomy was reattached and their visual acuity improved from CF to 0.4 and LP to CF, respectively. In ARN patients whose conditions could not be controlled by systemic antivirus medicine treatment, early intravitreal injection of Ganciclovir can yield satisfactory therapeutic effects and better visual prognoses if applied before the occurrence of PVR or retinal detachment.[Zhonghua yan ke za zhi] Chinese journal of ophthalmology 08/2007; 43(7):631-7.

ABSTRACT: To investigate the fundus characteristics, systemic features and therapeutic outcomes of cytomegalovirus (CMV) retinitis associated with acquired immunodeficiency syndrome (AIDS). 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). 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. 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.[Zhonghua yan ke za zhi] Chinese journal of ophthalmology 09/2005; 41(9):803-6.
