[Surgical treatment of the optic disc pit maculopathy].

PURPOSE

To evaluate long-term effects of anatomic and functional changes after the surgical treatment of the optic disc pit maculopathy in a retrospective study.

MATERIALS AND METHODS

Six patients with unilateral optic disc pit maculopathy were included in this study. Four were females and 2 males, age ranged from 13 to 35 years (mean, 26 years). All patients underwent the pars plana vitrectomy, internal limiting membrane peeling and the intraocular tamponade with the air-gas mixture. These 6 patients were divided into two groups: group A, the surgical treatment without aimed argon laser photocoagulation, and group B, the surgical treatment with aimed argon laser photocoagulation during 2 months after the pars plana vitrectomy. The follow-up period ranged from 41 to 73 months (mean, 53.3 months).

RESULTS

In the group A, the best-corrected visual acuity improved by 2 and more lines (Snellen optotype) in all 3 patients. In the group B, the improvement by 2 and more lines was found out in 2 patients and the decrease by 2 lines was observed in one patient. The recurrence of the maculopathy occurred in 2 patients from the group A. In the group B, the recurrence of the maculopathy was recorded in one patient 53 months after pars plana vitrectomy and aimed argon photocoagulation.

CONCLUSION

The surgical intervention by pars plana vitrectomy for the optic disc pit maculopathy improves the anatomic and functional prognosis. The suitable aimed argon laser photocoagulation after the surgical treatment in selected patients improves outcome and reduce the recurrence of the optic disc pit maculopathy.
