  • Title: [Photocoagulation treatment in hemorrhagic branch vein occlusion involving the macula. A new approach].
    Author: Meyer-Schwickerath R.
    Journal: J Fr Ophtalmol; 1989; 12(11):811-7. PubMed ID: 2639900.
    Abstract:
    Hemorrhagic infarction of the inner retinal layer in vein occlusion disables the ophthalmologist from placing the photocoagulation at the "usual" level of the pigment epithelium. On the other hand, resorption of the photocoagulation energy by hemoglobin gives the change of placing coagulation in the inner retinal layer with complete destroying of the retinal capillaries. The not affected part of the macula in branch vein occlusions can thus be prevented from being destroyed by the chronic edema. A photocoagulation barrier is placed between the macula and the affected side. The unavoidable destruction of parts of the nerve-fiber-layer has to be taken into account. If therapy does not start too late, excellent results can be obtained.
