IpModification of posterior vitrectomy in the treatment of optic disc maculopathy

Abstract

Purpose: Optic disc pit is rare congenital anomalies of the optic nerve. The optic disc pit is asymptomatic lesion. With the development of maculopathy associated with optic disc pit, visual acuity decreases dramatically. We present our result of the treatment for an optic disc pit maculopathy.

Methods: Case report

Results: A 39-year-old woman complained of a progressive decrease in visual acuity of the left eye to 20/200. Fundus image illustrated an optic disc pit. In the macular region, detachment of the neuroepithelium, reaching the optic disc, was revealed. The diagnosis of maculopathy associated with the optic disc pit was established. The diagnosis was confirmed by OCT data. Posterior vitrectomy was performed with the application of platelets-rich plasma into the pit of the optic disc. In 12 months the vision of the affected eye improved from 20/200 to 20/32. Fluid in the layers of the retina and subretinal fluid in the macular area disappeared.

Conclusion: There is no preventive treatment for maculopathy associated with optic disc pit.

Posterior vitrectomy in various modifications is the main method of treatment for maculopathy associated with optic disc pit. When performing a posterior vitrectomy, it is necessary to completely remove the posterior hyaloid membrane in order to avoid traction effects on the optic nerve pit. Restoration of vision after surgical treatment for a maculopathy associated with optic disc pit is a long process. The patient should be informed about this.
