Abstract
Purpose:
To compare the functional and anatomic outcomes of pars plana vitrectomy (PPV) with juxtapapillary laser photocoagulation (JLP) versus without JLP in optic disc pit maculopathy.
Methods:
Retrospective review of consecutive patients with optic disc pit maculopathy seen at two tertiary eye centers between 1992 and 2012. Twenty-six patients with optic nerve pit maculopathy were included. All patients underwent complete ophthalmic evaluation, fundus photography, fundus fluorescein angiography, and macular optical coherence tomography (OCT). Indications for surgery included distorted or decreased vision. Surgical intervention included PPV, posterior vitreous detachment, and gas tamponade. Fourteen patients had laser photocoagulation at the temporal edge of the optic disc pit (Group A) and 12 patients had no laser (Group B). Pre and postoperative snellen best-corrected visual acuity (BCVA) as well as OCT findings were recorded.
Results:
Mean follow up was 18 months (range: 2 to 52 months). LogMAR BCVA in Group A improved significantly from a mean of 0.85 to 0.54 (p = 0.003) at the last follow-up. In Group B, mean LogMAR BCVA improved from 0.88 to 0.64, however this difference was not significant (p = 0.528). Similarly, the mean OCT central macular thickness (CMT) in Group A improved significantly from 705.4 μm to 343 μm in the pre- and post-operative assessments, respectively (p = 0.001). Meanwhile, the corresponding change in mean CMT in Group B improved from 611.9 μm to 290 μm, however this difference was not statistically significant (p = 0.225).
Conclusions:
Patients who underwent pars plana vitrectomy with juxtapapillary laser photocoagulation for optic disc pit maculopathy showed better visual and anatomic outcome than those with no laser at the last follow-up.
