Summary:
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.
