OBJECTIVE: To evaluate the effect of treatment by lamina puncture, a novel procedure to create a perivascular opening within the optic nerve head by a transvitreal approach, on visual acuity after central retinal vein occlusion (CRVO) in older patients.

METHODS: The patients comprised a nonrandomized, consecutive, interventional case series of older patients being seen with CRVO. Patients 65 years or older with CRVO and a visual acuity of 20/200 or worse were treated with vitrectomy and lamina puncture of the optic disc. Preoperative visual acuity, clinical examination results, and fluorescein angiography results were compared with postoperative results.

RESULTS: Twenty patients (12 men and 8 women), an average age of 72 years, were enrolled. The mean duration of CRVO was 5.4 months; 14 eyes had nonischemic CRVO when first seen, while 6 had substantial ischemia. The mean preoperative visual acuity was in the counting fingers range, and the mean postoperative visual acuity was also in the counting fingers range. Complications included 5 eyes with iris neovascularization, of which 4 progressed to neovascular glaucoma; also, preoperative ischemia seemed to predispose to neovascular complications.

CONCLUSION: Lamina puncture does not restore visual acuity in older patients with CRVO.
