Abstract

Purpose : Optic disc pit is a rare congenital anomaly resulting from imperfect closure of the embryonic fissure. Serous macular detachment is the most common complication causing visual loss in 75% of these patients. There is currently no universally accepted gold standard of treatment for this condition. In the presence of serous macular detachment, a strategy combining pars plana vitrectomy, ILM peeling, laser photocoagulation and gas tamponade is often offered as first-line therapy. In refractory cases, several surgical alternatives have been recently described to seal the optic disc pit like scleral autograft, ILM free flap or fibrin sealant.
Herein, we report a case of large refractory optic disc pit maculopathy successfully treated by a novel surgical technique using a silicone lacrymal plug.

Methods : A 43-year-old female with a long-standing history of unilateral optic disc pit maculopathy was referred to our clinic. Her visual acuity was limited to 20/800 in the left eye because of refractory serous macular detachment for 2 years despite laser photocoagulation and two vitrectomy procedures with ILM peeling and C2F6 tamponade.
SD-OCT imaging revealed a large pit mesuring more than 900 μm in horizontal diameter and extended in depth over 1500 μm in the optical disk. The optic disc pit communicates with a wide sub-retinal fluid cavity that lifts the macula.
We decided to use a silicone lacrimal plug to fill the pit and thus mechanically prevent the penetration of subretinal fluid. The punctual plug was inserted into the vitreous cavity by a 20-gauge sclerotomy during a 23G pars plana vitrectomy. The positioning of the plug in the pit was performed with a 23G epiretinal membrane forceps. Finally, a 20% SF6 tamponade was performed to maintain the plug after fluid-air exchange.

Results : This unprecedented procedure allowed an excellent anatomical result with a total resolution of serous retinal detachment in 1 month.
Unfortunately, functional gain was low due to structural alterations of the outer retina previously induced by prolonged serous detachment. Visual acuity remained stable at 6 months.

Conclusions : This case suggests that silicone punctal plug can be considered as an interesting option in the surgical treatment of large optic disc pit-associated maculopathy. The functional benefit of this technique needs to be assessed in larger cohorts.
