Summary
Macular hole surgery in highly myopic eyes offers significant visual gains, though closure rates are lower than in other cases. This may necessitate repeat procedures for optimal outcomes.
Area of Science:
- Ophthalmology
- Retinal Surgery
Background:
- High myopia presents unique challenges for retinal surgery.
- Macular holes in highly myopic eyes require specific surgical considerations.
Purpose of the Study:
- To assess the anatomical and functional results of macular hole surgery in patients with high myopia.
- To determine the efficacy of surgical intervention for macular holes in myopic eyes.
Main Methods:
- Retrospective case series involving 20 eyes of 18 highly myopic subjects.
- Analysis of preoperative and postoperative visual acuity and macular hole closure rates.
- Pars plana vitrectomy was the primary surgical technique employed.
Main Results:
- Macular hole closure was achieved in 60% of eyes with one surgery and 85% with multiple surgeries.
- Mean final visual acuity improved to 20/63, with 40% experiencing a gain of over three Snellen lines.
- Adjunctive agents did not significantly impact closure rates or visual acuity.
Conclusions:
- Macular hole surgery can lead to substantial visual improvement in myopic eyes.
- Anatomical closure rates are lower compared to idiopathic macular holes, potentially increasing reoperation rates.
- Successful outcomes were observed even in cases with surrounding retinal detachments.
