[Postoperative choroid detachment following microsurgery for rhegmatogenous retinal detachment].

PURPOSE

To evaluate the incidence, predisposing and prognosis factors of post-operative choroidal detachment after microsurgery of rhegmatogenous retinal detachment.

MATERIALS AND METHODS

We conducted a retrospective study on a series of 595 consecutive rhegmatogenous retinal detachments referred before any previous failed surgery. Univariate statistical analysis of the data was conducted with evaluation of the odds ratio.

RESULTS

Postoperative choroidal detachment developed in 23/595 eyes (3.8%). Significant predictive factors for post operative choroidal detachment included patient's age over 50 years, male gender, pseudophakia, retinal detachment higher than 90 degrees and giant tears. We found no correlation between postoperative choroidal detachment and the retinopexy method, subretinal fluid release and the type of scleral buckling procedure (segmental versus incercling). Postoperative choroidal detachment did not influence at a statistically significant level the postoperative outcome. Permanent retinal reattachment was achieved in 20 of the 23 eyes (87%) with postoperative choroidal detachment, and 564 of 572 eyes (93%) with no post-operative choroidal detachment (p > 0.05). Postoperative PVR occurred in 3 of the 23 eyes (13%) with postoperative choroidal detachment and 3 of the 572 eyes (5%) with no postoperative choroidal detachment (p > 0.05). The postoperative visual outcome was not influenced by the occurrence of postoperative choroidal detachment.

CONCLUSION

Postoperative choroidal detachment after retinal detachment microsurgery is a rare complication. Its prognosis is good. The occurrence of postoperative choroidal detachment does not influence the postoperative outcome of retinal detachment microsurgery.
