Abstract
Purpose
To investigate the effects of internal limiting membrane (ILM) peeling on visual field sensitivities in eyes with epiretinal membrane (ERM) accompanied by glaucoma with hemifield defect and myopia.
Study design
Retrospective clinical study
Methods
We reviewed clinical records of patients with ERM who underwent vitrectomy and ERM/ILM peeling. We first collected clinical data of eyes with ERM and glaucoma with hemifield defect. We recorded visual field sensitivities at 52 points and analyzed differences between before and after surgery. We then compared the changes in visual field sensitivity between glaucomatous and normal hemifields. Next, we collected ERM eyes without glaucoma and stratified them into two groups based on axial length (threshold = 26.0 mm). In these eyes, we also recorded visual field sensitivities at 52 points and analyzed differences between before and after surgery.
Results
The study included 18 eyes with ERM and glaucoma with hemifield defect (11 men; mean age, 68.3 ± 7.2 years). These eyes showed significant sensitivity reductions at 5/26 points, mainly in the nasal area of the glaucomatous hemifield, whereas only 1/26 points exhibited significant sensitivity reduction in the normal hemifield. In eyes with axial length <26.0 mm and axial length ≥26.0 mm, 29 peripheral and seven superior peripheral points showed significant improvements in visual field sensitivities, respectively.
Conclusion
Visual field sensitivity reduction occurred mainly in the nasal region of the glaucomatous hemifield. Differences in axial length alone were not a prominent risk factor for reduced visual field sensitivity after ILM peeling in eyes with ERM.
