Summary
Pars plana vitrectomy effectively treated chronic pseudophakic cystoid macular edema (CME) unresponsive to medication. This surgical intervention resolved CME and improved visual acuity in many patients, even those without apparent vitreous disturbance.
Area of Science:
- Ophthalmology
- Surgical Retina
- Vitreoretinal Surgery
Background:
- Chronic pseudophakic cystoid macular edema (CME) can significantly impair vision after cataract surgery.
- Medical management often fails to resolve persistent CME.
Purpose of the Study:
- To evaluate the efficacy of pars plana vitrectomy (PPV) for chronic pseudophakic CME.
- To assess visual acuity outcomes and CME resolution following PPV.
Main Methods:
- Retrospective analysis of 23 eyes with chronic pseudophakic CME unresponsive to medical treatment.
- Exclusion of eyes with vitreous incarceration or vitreous-cornea contact.
- Standard pars plana vitrectomy with lysis of vitreous adhesions if present.
Main Results:
- Median visual acuity improved from 20/200 preoperatively to 20/60 postoperatively (P<.0001).
- CME resolved in all 23 eyes within a median of 2 months.
- Vitreous adhesion to anterior segment structures was noted in 52.2% of eyes.
Conclusions:
- Pars plana vitrectomy is an effective treatment for chronic pseudophakic CME refractory to medical therapy.
- Visual acuity improvement and CME resolution can be achieved with PPV.
- Positive outcomes may occur even in cases without obvious vitreous abnormalities.
