Photocoagulation in retinal venous occlusion. 1977

L Laatikainen

Results of retinal photocoagulation therapy in 26 eyes with retinal branch vein occlusion (RBVO) and in 18 eyes with central retinal vein occlusion (CRVO) are presented. The final visual outcome in eyes with macular oedema (non-ischaemic type of occlusion) did not significantly differ from that reported in various untreated series of branch or central retinal vein occlusion. Neovascular complications in eyes with capillary non-perfusion (ischaemic type of occlusion) could not be prevented with the relatively mild photocoagulation technique (less than 200 xenon burns in CRVO) used in this study. On the basis of this series the value of photocoagulation therapy in improving the visual prognosis in venous occlusion is questionable, and, in order to prevent neovascular complications in the ischaemic type of occlusion, a more extensive treatment seems to be necessary.

UI	MeSH Term	Description	Entries
D007511	Ischemia	A hypoperfusion of the BLOOD through an organ or tissue caused by a PATHOLOGIC CONSTRICTION or obstruction of its BLOOD VESSELS, or an absence of BLOOD CIRCULATION.	Ischemias
D008028	Light Coagulation	The coagulation of tissue by an intense beam of light, including laser (LASER COAGULATION). In the eye it is used in the treatment of retinal detachments, retinal holes, aneurysms, hemorrhages, and malignant and benign neoplasms.

D012169	Retinal Vein	Central retinal vein and its tributaries. It runs a short course within the optic nerve and then leaves and empties into the superior ophthalmic vein or cavernous sinus.

D014792	Visual Acuity	Clarity or sharpness of OCULAR VISION or the ability of the eye to see fine details. Visual acuity depends on the functions of RETINA, neuronal transmission, and the interpretative ability of the brain. Normal visual acuity is expressed as 20/20 indicating that one can see at 20 feet what should normally be seen at that distance. Visual acuity can also be influenced by brightness, color, and contrast.	Acuities, Visual,Acuity, Visual,Visual Acuities
