Objective: To evaluate the effect of different factors on the prognosis of rhegmatogenous retinal detachment (RRD) associated with choroidal detachment (ChD).
Methods: One hundred and eighty-eight eyes of 188 patients were studied retrospectively from Jan, 1996 to Aug, 1998. The clinical data, surgical management and follow-up records were analyzed.
Results: The total successful rate of the surgery was 83.0%, lower than that of general RRD. In the eyes with proliferative vitreoretinopathy (PVR) A-B, the rate was 89.6%, in the eyes with C(1)-C(3) PVR, the rate was 84.1%, in D(1)-D(3), 69.0%. In eyes with severe PVR the successful rate of vitrectomy was higher than that of scleral buckling alone. Administration of steroids before surgery resulted in high successful rate, but the length of time of the steroid treatment had no effect on the successful rate. In the eyes using scleral buckling alone, the drainage or without the drainage of subretinal fluid had no effect on the successful rate.
Conclusions: RRD associated with ChD has worse prognosis than general RRD. The administration of steroids before surgery is necessary, and the timing of surgery is also important. In eyes with light PVR and ChD, scleral buckling without drainage of subretinal fluid is the first choice, but in eyes with severe PVR and ChD, vitrectomy is a better choice.
