Acute retinal necrosis complicating chickenpox in a healthy adult--a case report and review of literature.

Acute retinal necrosis (ARN) is known to occur in conjunction with primary varicella or chickenpox infection. The majority of ARN cases reported in the literature were of milder form with mild to moderate vitritis, limited retinitis, and rare occurrence of retinal breaks or detachment that responded well to intravenous acyclovir, with or without oral prednisolone. We report a case of unilateral ARN with marked vitritis and retinal necrosis leading to retinal breaks following chickenpox in a 32-year-old healthy lady. This patient was successfully treated with intravenous acyclovir followed by oral acyclovir and orbital floor triamcinolone injections to contain the inflammation with barrier laser therapy to secure the retinal breaks with good visual outcome. This case is unusual in its severity, and to our knowledge, orbital floor triamcinolone therapy was not used earlier to contain ARN inflammation

Changes in anterior chamber depth and intraocular pressure after phacoemulsification in eyes with occludable angles

PURPOSE: To evaluate changes in anterior chamber depth (ACD) and intraocular pressure (IOP) after phacoemulsification in eyes with occludable angles and compare the results with those in eyes with normal open angles. SETTING: Eye Clinic, Ipoh General Hospital, Ipoh, Perak, Malaysia. METHODS: Patients with nonglaucomatous eyes with open angles or with occludable angles were recruited. Ocular biometric measurements (ACD, axial length [AL], lens thickness and position) and IOP (tonometry) were performed preoperatively and 1 day and 1, 4, 9, and 12 weeks postoperatively. RESULTS: The open-angle group and occludable-angle group each comprised 35 patients. The occludable-angle group had a shallower ACD, shorter AL, thicker and relatively anterior lens position, and higher IOP preoperatively; postoperatively, there was a significant increase in ACD and a significant reduction in IOP (P<.01). Anterior chamber deepening was inversely related to preoperative ACD in the occludable-angle group (P<.01). The mean preoperative IOP was higher in the occludable-angle group (15.77 mm Hg +/- 2.20 [SD]) than in the open-angle group (14.52 +/- 2.65 mm Hg) (P<.05). The IOP dropped progressively and significantly over 12 weeks postoperatively; the mean decrease was 2.31 +/- 0.99 mm Hg in the occludable-angle group and 0.77 +/- 1.17 mm Hg in the open-angle group. The IOP decrease in the occludable-angle group was inversely related to the preoperative IOP (P<.01). CONCLUSION: Phacoemulsification led to anterior chamber deepening and lower IOP in eyes with occludable angles, which suggests it is an option for preventing acute angle closure attacks in eyes with occludable angles and cataract
