1. Device and method for photocoagulation of the retina

2. Objective To investigate the effect of krypton laser photocoagulation on branch retinal vein occlusion.

3. Objective To evaluate the therapeutic effect of krypton yellow laser photocoagulation for central serous chorioretinopathy ( CSC ).

4. In contrast to conventional laser photocoagulation, which is associated with complete thermal necrosis of and around the treated site, absolutely no scotoma occurs in SRT.

5. An amount of 60 calories per square centimeter must be received by the retina in a mean time of 2′′ 75 to obtain a destructive and non reversible photocoagulation.

6. The findings to focus on are: position and extent of pathologic vascular proliferation, activity of fibrovascular proliferation, Angioplany of the retina, absence of capillary network of the retina, extent of photocoagulation, and stabilizing of the vascular activity …

7. Particular caution should be exercised, and intensified blood glucose monitoring is advisable in patients in whom hypoglycaemic episodes might be of particular clinical relevance, such as in patients with significant stenoses of the coronary arteries or of the blood vessels supplying the brain (risk of cardiac or cerebral complications of hypoglycaemia) as well as in patients with proliferative retinopathy, particularly if not treated with photocoagulation (risk of transient amaurosis following hypoglycaemia
