Vitreous surgery for macular holes

Abstract

Background: To surgically treat patients with macular holes, the authors previously reported both anatomic (re-attachment) and visual success (2 lines of improvement) in a series of 52 eyes. They now have operated on an additional 118 eyes using similar techniques, for a total of 170 eyes.

Methods: After ophthalmologic examination and history, the authors operated on suitable patients. The surgical objectives included relief of all tangential traction and retinal tamponade with intraocular gas. All eyes were followed for at least 6 months postoperatively.

Results: In the total population of 170 eyes, anatomic success was achieved in 73% and vision improved at least two lines in 55%. Twenty-nine percent (49/170) of patients had a visual acuity of 20/40 or better at last examination. Patients with symptoms of less than 6 months' duration managed better than those with symptoms of longer duration (P = 0.3001). In the former group of 66 eyes, anatomic success was achieved in 80% (n = 53), whereas visual acuity improved at least two lines in 68% (n = 45) and at least four lines in 55% (n = 36).

Conclusions: The authors suggest that macular hole surgery may provide meaningful improvement in visual acuity in most patients, especially in those whose symptoms are of less than 6 months' duration.
