[Retinal detachment. The vitrectomy technique].

One hundred and ten eyes from 110 patients who in 1992 had undergone vitrectomy for regmatogenous retinal detachment were included in a retrospective study. Two year follow-up was obtained for 97 eyes. At the end of follow-up 45% of the eyes had complete anatomical success. Fifty-five percent had attachment of the macula. Anatomical success after a single operation was obtained in 33%. A visual acuity of more than 0.05 was obtained for 35% of the eyes at the end of follow-up. Eighty patients had a follow-up interview; of these 56% stated that the advantages of the operation outweighed the disadvantages.
