    Abstract:
    BACKGROUND: Pars plana vitrectomy, usually without additional buckling procedures, is the first choice for repair of pseudophakic retinal detachment at the Lucerne Eye Hospital. PATIENTS AND METHODS: In a retrospective study we analyzed a consecutive series of 129 eyes (122 patients) treated for pseudophakic retinal detachment. All underwent a primary pars plana vitrectomy. 97 % had retrobulbar anaesthesia. SF6 was used in 93 %, Si-oil in 7 %. An additional encircling band was placed in 5 %. Mean age was 65 years (24 - 92, +/- 13). Minimal follow-up was 8 months (8 - 66, median 25). RESULTS: Mean duration of surgery was 90 minutes (50 - 140, +/- 15). Severe PVR grade C was present in 17 %. Breaks in the inferior part of the retina were found in 52 % - the localisation had no influence on the anatomical or functional outcome. A difference between preoperative and intraoperative findings was noted in 46 % (missed breaks or lattice degenerations etc.). For general medical reasons, Si-oil was not removed in 4 eyes. Complete reattachment after the first operation was achieved in overall 91 % (oil-left eyes were considered as failure); in 95 %, if the oil-left eyes were excluded from the study; in 93 %, if the eyes with encircling band were not counted; in 95 % without encircling-band and oil-left eyes; in 93 % without PVR-C cases; 95 % without encircling-band/oil-left/PVR-C eyes. Median final visual acuity was 1.0, if the macula was not detached preoperatively and 0.8, if the macula was detached. Intraocular pressure problems (> 30 mm Hg < 12 h and/or > 25 mm Hg > 36 h) were noted in 28 %. Prophylactic or therapeutic antiglaucomatous medication was applied in 58 %. 14 % showed a transient fibrin reaction in the anterior segment. Refraction and ocular motility were not influenced by the surgery. CONCLUSION: Primary vitrectomy for pseudophakic retinal detachment is safe and effective. Transient elevation of the intraocular pressure is a frequent postoperative complication.
