Thoughts and Challenges for the Current Treatment of Optic Disc Pit Maculopathy

ABSTRACT

Purpose

The present review describes the procedures that intervene directly in covering and stuffing the optic disc pit (ODP).

Methods

We made a comprehensive review of the literature regarding the new treatment modalities for the treatment of ODP maculopathy, mainly concentrated on covering and stuffing of the ODP. We presented the anatomical and functional outcomes of these techniques in patients with ODP maculopathy, while potential risks and complications of these techniques are also discussed.

Results

The most commonly used treatment alternative for ODP maculopathy is vitrectomy, which seems to be more successful if it is associated with the covering of the ODP by internal limiting membrane (ILM) inverted flapping. The results of the procedure are successful, if the origin of the fluid comes from the vitreous cavity. Another new procedure aims at the stuffing of the ODP by rolled ILM-flap, autologous scleral tissue or human amniotic membrane, providing promising anatomical results. The so far anatomical and functional results are discussed in detail. The literature, however, is limited regarding these techniques and based mainly on case reports with short-term follow-up. Additionally, the stuffing technique is possible to provoke further damage of optic nerve tissue and remain challenging in its use.

Conclusions

Both covering and stuffing techniques of the ODP seem to have promising results, when used as adjunct to vitrectomy. One should take into account special considerations and possible further complications for their use in the treatment of ODP maculopathy.
