Optical coherence tomography in the detection of retinal break and management of retinal detachment in morning glory syndrome.

PURPOSE

To determine the efficacy of optical coherence tomography (OCT) in the management of retinal detachment in morning glory syndrome (MGS).

DESIGN

Prospective, interventional case series.

METHODS

Five eyes of five consecutive MGS patients who developed retinal detachment between August 2000 and June 2004 were enrolled and examined by OCT at presentation of retinal detachment. Four eyes were found to have a slit-like break at the margin of the excavation by careful OCT scanning 360 degrees around the excavation. All four eyes underwent pars plana vitrectomy, gas injection and postoperative laser photocoagulation. Postoperative OCT was performed to confirm the closure of the retinal break and reattachment of the retina.

RESULTS

Optical coherence tomography detected a slit-like break at the margin of excavation in four of five patients. The retina reattached in all five eyes over the subsequent 3-50-months (average 28 months) follow-up period. Postoperative OCT showed retinal break closure at the margin of the excavation. In the one eye in which no retinal break could be detected by OCT, the retina was reattached after pars plana vitrectomy and removal of gel-like tissue.

CONCLUSIONS

Optical coherence tomography is beneficial in the detection of subtle slit-like breaks at the margin of excavation in retinal detachment in MGS. It provides good guidance in subsequent surgery and is very helpful in confirming the closure of the retinal break.
