PARS PLANA VITRECTOMY FOR PSEUDOPHAKIC RETINAL DETACHMENT

Peter Senn, M. K. Schmid (Luzern)

Background: Pars plana vitrectomy, usually without additional buckling procedures, is the first choice for repair of pseudophakic retinal detachment at the Lucerne Eye Hospital. We report on our results.

Patients and Methods: In a retrospective study we analyzed the outcome of 129 eyes (122 patients) after primary pars plana vitrectomy for pseudophakic retinal detachment. Mean age was 65 years (24-92, ± 13). Minimal follow-up was 8 months.

Results: Mean duration of surgery was 90 minutes (50-140, ± 15). 97 % had retrobulbar anesthesia. SF6 was used in 93 %, Si-oil in 7 %. Surgery was considered to be successful after Si-oil removal only . An additional encircling band was used in 5 %. Breaks in the inferior part of the retina were found in 52 %. Reattachment after the first operation was achieved in 91 %, respectively in 95 % if the four eyes were excluded where Si-oil was left for other medical reasons. A difference between preop and intraop findings was noted in 46 %. Prophylactic or therapeutic antiglaucomatous medication was applied in 58 %. 14 % showed a transient fibrin reaction in the anterior segment. Refraction and ocular motility was not influenced by the surgery.

Conclusion: Primary vitrectomy for pseudophakic retinal detachment is effective. Additional buckling procedures are not necessary in most cases.
