Complications of krypton red laser photocoagulation to subretinal neovascular membranes. 1984

W M Grabowski, and W L Decker, and W H Annesley

The use of krypton red laser photocoagulation (KRLPC) to treat subretinal neovascular membranes (SRNVM) is increasing. The complications of this treatment in a large series of patients have not been reported. Over a 15-month period, 195 patients had KRLPC to SRNVM of the following etiologies: senile macular degeneration (151), presumed ocular histoplasmosis (33), miscellaneous (11). Fourteen patients had the following complications attributable to KRLPC: choroidal hemorrhage (9), retinal pigment epithelial tears (3), choroidal ischemia (1) and choroidal folds (1). The visually significant complication rate was 3.6%. Proper patient selection and treatment technique may decrease the risk of complications.

UI MeSH Term Description Entries
D007726 Krypton A noble gas that is found in the atmosphere. It has the atomic symbol Kr, atomic number 36, atomic weight 83.80, and has been used in electric bulbs.
D007834 Lasers An optical source that emits photons in a coherent beam. Light Amplification by Stimulated Emission of Radiation (LASER) is brought about using devices that transform light of varying frequencies into a single intense, nearly nondivergent beam of monochromatic radiation. Lasers operate in the infrared, visible, ultraviolet, or X-ray regions of the spectrum.

Angiogenesis, Pathologic,Angiogenesis, Pathological,Neovascularization, Pathological,Pathologic Angiogenesis,Pathologic Neovascularization,Pathological Angiogenesis,Pathological Neovascularization
D012163 Retinal Detachment Separation of the inner layers of the retina (neural retina) from the pigment epithelium. Retinal detachment occurs more commonly in men than in women, in eyes with degenerative myopia, in aging and in aphakia. It may occur after an uncomplicated cataract extraction, but it is seen more often if vitreous humor has been lost during surgery.
