Optic disc pit is generally associated with serous macular detachment resulting in decreased visual acuity (VA) in more than 50 % of the patients. Existing techniques to plug the optic disc pit involves use of fibrin glue/sclera, which have their own inherent drawbacks. The autologous tissue is the most physiological, creating a permanent barrier to flow of fluid across pit. Surgery entails standard pars plana vitrectomy with PVD induction. ILM was stained with brilliant blue dye & peeled, its pedicle attached to edge of disc, inverted & inserted to seal the optic disc pit. Next, photocoagulation along temporal edge of pit was done followed by fluid air exchange and Air- C3F8 exchange. Patient was advised prone positioning.
BCVA improved from 6/120 through 6/12 at 3 months which was maintained in subsequent follow-ups. Optical Coherence Tomography examination confirmed the sealing of the optic disc pit with ILM.
The proposed technique shows excellent anatomic and functional results.
