Abstract
Purpose::
to evaluate the functional and anatomical outcome of lamellar macular hole surgery.
Methods::
twenty consecutive eyes of 20 patients with lamellar macular hole, assessed by OCT, underwent pars plana vitrectomy with internal limiting membrane peeling. In 85% of the eyes residual undetached cortical vitreous was found at the posterior pole after posterior vitreous detachment. Air was used as internal tamponade.BCVA and OCT data were evaluated preoperatively and 3, 6 and 12 months after surgery.
Results::
80% of the patient had improved vision by 2 or more lines, 20% of the eyes remained stable (+/- 1lines), none had decreased vision by 2 or more lines. The mean BCVA improved from 20/45 to 20/23; the mean foveal thickness increased from 99 micron to 175 micron. All lamellar holes were closed after a single surgery.
Conclusions::
this study suggests that macular surgery achieves excellent anatomical closure and is associated with significant functional improvement.
