Surgical results of Vitrectomy for Diabetic Macular Heterotopia

ABSTRACT

PURPOSE: This study aimed to investigate visual prognosis and postoperative complications of vitrectomies for macular heterotopia, and compare it with that of tractional macular detachment. METHODS: Medical records of 10 eyes which had undergone pars plana vitrectomy for diabetic macular heterotopia and 21 eyes which for diabetic tractional macular detachment in the 202 patients who had been diagnosed as proliferative diabetic retinopathy at Pusan Paik hospital from January, 1995 to december, 1998 were reviewed to study their clinical features, complications, visual outcome. RESULTS: Final postoperative improved visual acuity was documented in 70% of patients with macular heterotopia and 38% of patients with tractional macular detachment (P>0.05). Postoperative vitreous hemorrhage and cataract developed in 20% and 10% of patients with macular heterotopia and 19% and 10% of patients with tractinal macular detachment. Patients with macular heterotopia experienced retinal detachment and macular hole. Patients with tractional macular detachment experienced increased IOP, neovascular glaucoma and phthisis. CONCLUSIONS: Although we could not revealed statistical significance, the surgical results of vitrectomy for diabetic macular heterotopia was better than that of diabetic tractional macular detachment and in the view of vision and complications, diabetic macular heterotopia was more favorable.
