Surgical decompression in branch retinal vein occlusion

Mester U., Löw M., Dillinger P.

Department of Ophthalmology, Bundesknappschaft´s Hospital Sulzbach, An der Klinik 10, D-66280 Sulzbach

The characteristics of BRVO and its late complications as persistent macular edema and neovascularisation are demonstrated. Due to a common adventitial sheath, the vein can be compressed by an overlying artery at the site of an arteriovenous crossing. This pathomechanism leading to BRVO is shown schematically. Separation of the crossing artery from the compressed vein by dissection of the adventitial sheath is the logical therapeutic consequence. The surgical technique is demonstrated in two cases, in the second case with additional preparation of the altered internal limiting membrane. Functional results in 37 cases are shown and compared to a control group. Typical pre- and postoperative findings in Fluorescein angiography and Multifocal ERG are presented.
