Summary
Macular hole surgery can cause visual field defects in 23% of patients. Peripheral scotomas and relative arcuate defects were observed, with increased intraocular pressure potentially linked to arcuate defects.
Area of Science:
- Ophthalmology
- Retinal Surgery
Background:
- Macular holes are a common cause of central vision loss.
- Surgical repair is the standard treatment for full-thickness macular holes.
Purpose of the Study:
- To investigate the incidence of peripheral visual field loss following macular hole surgery.
- To characterize the types of visual field defects observed postoperatively.
Main Methods:
- Prospective study of 30 patients undergoing macular hole surgery.
- Preoperative and postoperative Goldmann visual field testing.
- Surgical technique included pars plana vitrectomy and fluid-gas exchange, with some receiving autologous platelet injection.
Main Results:
- 23% of patients (7/30) developed postoperative visual field defects.
- Four patients (13%) experienced peripheral scotomas.
- Three patients (10%) developed relative arcuate defects, with higher intraocular pressure noted in this group.
Conclusions:
- Macular hole surgery is associated with a significant incidence of visual field defects.
- Peripheral and relative arcuate scotomas are the main types observed.
- The etiology of peripheral visual field loss remains unclear, while elevated intraocular pressure may contribute to arcuate defects.
