[Retinal detachment after Excimer laser (myopic LASIK or PRK). A retrospective multicentric study: 15 cases].

Introduction: Refractive surgery by LASIK or photorefractive keratectomy (PRK) generaly aims at a myopic population that has a high probability of developing rhegmatogenous retinal detachment (RD). The authors report a multicenter study with 15 cases of RD appearing after refractive surgery by Excimer laser and discuss the role played by the techniques used.

Material And Methods: Five centers fitted with nine Excimer laser devices took part in this study.

[Remission of non-proliferative diabetic retinopathy following central retinal artery obstruction].

We report a case of central artery obstruction in a 55-year old man who had non proliferative diabetic retinopathy. Three years later, examination found no diabetic retinopathy in the eye that had central artery obstruction, and more advanced non proliferative diabetic retinopathy in the fellow eye. Pathogenic mechanisms for diabetic retinopathy regression after central artery occlusion could be the optic atrophy and ischemia of the inner retina associated to the decrease in retinal blood flow.
