[Undergoing retinal detachment and primitive ocular hypertension (author's transl)].

In a survey of 907 patients undergoing retinal detachment surgery, primitive ocular hypertension was found in 3,85%. This ocular hypertension was most often bilateral (85,7%) with open angle (88%) and was found at the time of retinal surgery or on the follow up (54,3%). Retinal detachments in these patients offered no particular character. This percentage of 3,85% is not greater than the percentage of primitive ocular hypertensions in a normal population over 40 years old. However the analysis of our data leads us to think that the presence of ocular hypertension increases the risk of retinal detachment when the patient is aphakic.
