Clinical presentation and surgical outcomes in primary myopic macular hole retinal detachment

PURPOSE. To describe the clinical presentation of primary macular hole retinal detachment (MHRD) secondary to high myopia and to evaluate the surgical outcomes. METHODS. Nine eyes of 9 patients with primary myopic MHRD (axial length >= 26.5 mm) were enrolled. A standardized surgical protocol was performed using vitrectomy with preservative-free triamcinolone acetonide-assisted internal limiting membrane (ILM) peeling and silicone oil tamponade and were followed for at least 6 months from the first surgery. RESULTS. There were 6 women and 3 men with a median age of 52 years. Six (66.6%) patients presented with inferior bullous configuration and 3 had subtotal retinal detachment. The mean preoperative refractive error (spherical equivalent) and mean axial length was 12 +/- 3.553 D (range 8.50-19.50) and 28.13 +/- 1.65 mm (range 26.50-31.50), respectively. The patients were followed up for a period of at least 6 months. The retina was attached and macular hole closed in all the eyes. There was significant visual acuity improvement from mean preoperative visual acuity of logMAR 1.85 +/- 0.11 (range 1.76-1.93) to postoperative visual acuity of logMAR 0.95 +/- 0.14 (range 0.84-1.06) (p<0.001). CONCLUSIONS. Retinal detachment in highly myopic eyes can often be secondary to a macular hole with predominance of inferior bullous configuration and primary vitrectomy with ILM peeling with silicone oil tamponade results in good anatomic and functional outcomes.
