Vascular remodeling in central retinal vein occlusion following laser-induced chorioretinal anastomosis.

چکیده
Report of a Case. A nondiabetic 80-year-old woman had an asymptomatic central retinal vein occlusion in her left eye. It was diagnosed during her scheduled 6-month follow-up visit with her general ophthalmologist. On her initial visit, she was using dorzolamide hydrochloride, 2%, and timolol, 0.5%, combination eyedrops at night in both eyes for her glaucoma. Her visual acuity was 20/20 OU and her intraocular pressure was 14 mm Hg OU. She had retinal hemorrhages in all 4 quadrants with dilated retinal veins. Fluorescein angiography showed a retinal recirculation time of 10 seconds, and the average central foveal thickness with Stratus optical coherence tomography was normal at 218 m. One month later, her visual acuity decreased to 20/70 OS and she had increased retinal hemorrhage and cystoid macular edema. The retinal veins were dilated, including the tributary connecting the inferotemporal branch retinal vein to the central retinal vein (Figure 1A). The average central foveal thickness on Stratus optical coherence tomography had increased to 511 m. Fluorescein angiography was not repeated. She was treated with 2 laser spots inferior to the optic nerve at a site where a retinal vein crossed over a choroidal vein. The first laser spot intentionally ruptured the Bruch membrane and the second laser spot intentionally nicked the retinal vein, causing a localized retinal hemorrhage.

Induced chorioretinal venous anastomosis in experimental retinal branch vein occlusion.
Iatrogenic retinal vein to choroidal vein anastomoses were created using laser photocoagulation in six of seven dog eyes in which a partial branch retinal vein occlusion had previously been created photochemically. A similar attempt to create an anastomosis was made in six control eyes in which no branch vein occlusion was present. In the eyes in which a branch retinal vein had been created, a ...

PURPOSE To evaluate the success rate of laser chorioretinal anastomosis (L-CRA) creation with a new laser photocoagulator system capable of 5 watts (W) power in patients with central retinal vein occlusion (CRVO). METHODS Patients with a treatment-naive CRVO were enrolled as part of an ongoing trial combining L-CRAs with anti-vascular endothelial growth factor treatment. RESULTS Thirty-thre...

AIM To evaluate the safety and efficacy of surgical induction of chorioretinal venous anastomosis in the management of ischaemic central retinal vein occlusion (CRVO). METHODS In a comparative clinical trial, 28 patients with ischaemic CRVO were included, of whom 18 who declined surgery were considered as controls. The 10 surgical cases underwent standard vitrectomy with incisions into the ch...
