Surgical removal of peripapillary subretinal neovascular membranes (PSRNVMs) in elderly patients preserved foveal function. This effective treatment for PSRNVMs showed initial visual acuity improvement and a low early recurrence rate.
Area of Science:
- Ophthalmology
- Retinal Surgery
Background:
- Peripapillary subretinal neovascular membranes (PSRNVMs) threaten vision in elderly patients.
- Subretinal fluid, hemorrhage, or exudate associated with PSRNVMs can lead to vision loss.
Purpose of the Study:
- To evaluate the surgical removal of extrafoveal PSRNVMs in elderly patients.
- To assess the impact of surgery on visual acuity and foveal function.
Main Methods:
- Retrospective review of six eyes from six patients.
- Subretinal surgical removal of PSRNVMs via pars plana vitrectomy.
Main Results:
- Successful PSRNVM removal in all six eyes, preserving foveal function.
- Postoperative visual acuity ranged from 20/25 to 20/40, with 83% stable or improved at 3 years.
- Early recurrence in 17% treated with laser; late recurrence in two eyes after 3 years. Cataracts developed in three phakic eyes.
Conclusions:
- Surgical removal of PSRNVMs sparing the fovea is feasible in elderly patients.
- The procedure offers initial preservation of foveal function.
- A low rate of early recurrence was observed.
