Vitrectomy Combined With Gas Tamponade for the Treatment of Morning Glory Syndrome With Rhegmatogenous Retinal Detachment: A Case Report.

We report a case of a 26-year-old male patient who was diagnosed with morning glory syndrome (MGS) in his right eye through a series of specialist examinations. At the time of consultation, the patient had already experienced retinal detachment in his right eye. The fundus of the right eye showed a 360° grayish-white elevation of the entire retina, with an enlarged optic disc approximately 4-5 times the normal size, featuring a central funnel-like deep depression. The surface of the optic disc was covered with grayish-white glial tissue, and elevated ridges with pigmentation were visible around the disc. Several straight vessels radiated from the edge of the optic disc, making it difficult to distinguish between arteries and veins. A comprehensive preoperative fundus examination failed to uncover any conclusive retinal tears. We performed a 25-gauge vitrectomy through the pars plana, and during the surgery, a small retinal tear was found at the nasal edge of the optic disc. After air-fluid exchange, laser photocoagulation of the retina was performed around the edge of the optic disc, followed by injection of 14% C3F8 gas. One month postoperatively, the gas was completely absorbed, and after a six-month follow-up, the retina was well-repositioned.
