Abstract

Purpose: To evaluate the factors related to outcome of vitrectomy for retinal detachment caused by macular hole. Methods: A cross-sectional descriptive study of 52 macular hole retinal detachment eyes that underwent vitrectomy in combination with inner limiting membrane peeling and intraocular gas (C3F8) or silicone oil at the Viet Nam National Institute of Ophthalmology from 2015 to 2019 with a minimum follow-up of 6 months. Results: The rate of retinal reattachment after the primary surgery was 80.8%. The rate of macular hole closure was 61.5%. Mean visual acuity increased from 1.99 ± 0.31 logMAR to 1.35 ± 0.26 logMAR at the last examination. Disease duration more than 6 months, poor preoperative visual acuity, axial length more than 26 mm, posterior staphyloma and large macular hole size are factors that reduce the rate of retinal reattachment and macular hole closure after surgery. The extent of retinal detachment reduces the possibility of macular hole closure while intraocular tamponade affects only the rate of postoperative retinal reattachment. The size of the macular hole was the only factor affecting postoperative visual acuity (p = 0.009). Conclusion: Vitrectomy for macular hole retinal detachment has good anatomical results, but postoperative visual acuity are still low. Disease duration, preoperative visual acuity, axial length, posterior staphyloma, macular hole size, extent of retinal detachment and intraocular tamponade were factors that influenced the anatomic results while the size of the macular hole affects the visual outcome of surgery.
