Pars plana vitrectomy for aphakic cystoid macular edema
Retina (Philadelphia, Pa.)
|January 1, 1985
Summary
This study shows that combining limbal and pars plana vitrectomy effectively treats chronic aphakic cystoid macular edema caused by vitreous incarceration. Surgical intervention improved vision in most patients.
Area of Science:
- Ophthalmology
- Surgical Techniques
Background:
- Chronic aphakic cystoid macular edema (CME) can significantly impair vision.
- Vitreous incarceration in the cataract wound is a known cause of persistent CME.
Purpose of the Study:
- To evaluate the efficacy of a combined limbal and pars plana vitrectomy approach.
- To treat chronic aphakic cystoid macular edema associated with vitreous incarceration.
Main Methods:
- A combined limbal and pars plana vitrectomy was performed on 17 eyes (16 patients).
- Surgical criteria included visual acuity of 20/50 or worse, confirmed CME, and persistent edema (>6 months).
- Vitreous removal from the limbal wound was the primary surgical goal.
Main Results:
- Successful vitreous removal from the limbal wound was achieved in 16 out of 17 eyes (94%).
- Postoperative visual acuity improved by two lines or more in 11 eyes (65%).
Conclusions:
- Combined limbal and pars plana vitrectomy is an effective surgical option.
- This technique successfully addresses vitreous incarceration contributing to chronic aphakic CME.
- Significant visual improvement can be expected following the procedure.
