Purpose: To evaluate visual acuity outcome of successful vitrectomy and gas tamponade, with laser photocoagulation for the treatment of macular detachment associate with congenital optic disk pit.
Participants: Twenty-one consecutive patients (21 eyes, 11-54 years of age) with optic disc pit and serous macular detachment were treated with vitrectomy procedure and followed up from October 2006 to March 2011.
Intervention: Pars plana vitrectomy, induction of posterior vitreous detachment (PVD), gas tamponade, and laser photocoagulation were performed, with postoperative facedown positioning for 2 weeks. Optical coherence tomography (OCT), Fundus fluorescein angiography (FFA) and visual acuity examination were recorded before and after treatment. Patients were observed for 9 to 75 months after surgery.
Results: In all 21 eyes included in the study and successfully treated, an improvement in visual acuity was documented. Median preoperative best-corrected visual acuity was 20/100 (range, 20/50 to counting fingers). Median postoperative best-corrected visual acuity was 20/25 (range, 20/17 –20/50). 15 eyes (71.4%) achieved a final VA of 20/25 or better. The OCT before treatment showed serous macular detachment in all eyes. Two months after the surgical intervention, complete retinal reattachment was achieved in all 21 eyes. No recurrences were observed.
Conclusion: Improvement of visual acuity was recorded after the treatment of congenital optic disk pit maculopathy with vitrectomy, gas tamponade and laser photocoagulation procedure. This technique seems to be effective for treatment of the disease with good anatomic and functional results.
