“…In 62.5% (10/16) of eyes with maculopathy, vitreomacular traction extending from the optic nerve head to the macula was detected on OCT preoperatively 7. Interestingly, the presence of dense vitreous strands adhering to optic disc pits, resembling the membrane tissue in our present case, has been previously documented 7,9. In 87.5% (7/8) of eyes with optic disc pit maculopathy without PVD, maculopathy resolved following PPV with induction of PVD at the optic disc, without laser photocoagulation or gas tamponade 8.…”

This article reports a case of possible involvement of membrane tissue on the optic disc with macular schisis formation associated with glaucomatous optic disc without optic disc pits. A 78-year-old man presented with loss of central visual acuity of the left eye. He had a medical history of primary open-angle glaucoma. Visual acuity was 0.6 in his left eye, and funduscopy revealed macular schisis and a glaucomatous optic disc without optic disc pits. Optical coherence tomography (OCT) revealed membrane tissue on the optic disc and a tunnel-like hyporeflective lesion connecting the schisis cavity and a site near the tissue, but no obvious optic disc pit. He underwent pars plana vitrectomy during which the membrane tissue on the disc and internal limiting membrane were removed. Posterior vitreous detachment was observed intraoperatively. Thereafter, the tunnel-like lesion observed on OCT was rapidly obscured and the macular schisis gradually reduced. Eighteen months after surgery, his visual acuity had improved to 0.9 with almost complete regression of the macular schisis. No optic disc pit was visualized after surgery. The changes in OCT findings described here suggest an etiology for macular schisis without optic disc pits in an eye with a glaucomatous optic disc with posterior vitreous detachment. A connection between the schisis cavity and the vitreous cavity may have appeared via the tunnel-like structure due to the membrane tissue exerting traction on the optic disc.

“…Intraoperative observations during vitrectomy for the treatment of optic disc pit maculopathy emphasize the role of the vitreoretinal interface in the pathogenesis of macular detachment associated with optic disc maculopathy in a number of case reports [2,3,7,12,14,16,18]. Moreover the good surgical results after the release of vitreous traction by vitrectomy [8,15] or scleral buckling procedure [32,35] further strengthens the view that the vitreous participates in the pathogenesis of the optic disc pit maculopathy.…”

OCT was able to detect vitreous abnormalities such as vitreomacular traction, vitreous strands over the optic disc and complete or partial posterior vitreous detachment associated with optic disc pit maculopathy. Our observations support the view that the abnormal vitreous over the macula and optic disc is likely to play a role in the development of macular elevation in cases with optic disc pit. Prospective OCT studies could further assist to better understand the role of vitreous in this disease.

“…Snead et al [58] reported a case of a 9-year-old boy with ODP-M successfully treated with vitrectomy, endolaser, and SF6 tamponade without ILM peeling. Hirakata et al [59] treated an 8-year-old girl with vitrectomy and gas, while an unusual posterior hyaloid strand connected with the ODP was removed with forceps. Laser photocoagulation followed by vitrectomy, ILM peeling, and gas tamponade was performed with favorable results by Ishikawa et al [60] in a 7-year-old girl with ODP-M.…”

Optic disc pits are a very rare clinical entity, affecting approximately one in 11,000 people. Patients with congenital optic disc pit sometimes remain asymptomatic, but 25% to 75% present with visual deterioration in their 30s or 40s after developing macular schisis and detachment. The most widely accepted treatment for such patients is a surgical approach involving pars plana vitrectomy with or without internal limiting membrane peeling, with or without endolaser photocoagulation and C3F8 endotamponade.
