          Abstract

          Purpose: To report a case of spontaneous resolution of a long-standing serous macular detachment associated with an optic disc pit, leading to significant visual improvement. Case Presentation: A 63-year-old female presented with a 6-month history of blurred vision and micropsia in her left eye. Her best-corrected visual acuity was 6/24 in the left eye, and fundoscopy revealed serous macular detachment associated with optic disc pit, which was confirmed by optical coherence tomography (OCT). The patient was offered vitrectomy as a treatment alternative, but she preferred to be reviewed conservatively. Three years after initial presentation, neither macular detachment nor subretinal fluid was evident in OCT, while the inner segment/outer segment (IS/OS) junction line was intact. Her visual acuity was improved from 6/24 to 6/12 in her left eye, remaining stable at the 6-month follow-up after resolution. Conclusion: We present a case of spontaneous resolution of a long-standing macular detachment associated with an optic disc pit with significant visual improvement, postulating that the integrity of the IS/OS junction line may be a prognostic factor for final visual acuity and suggesting OCT as an indicator of visual prognosis and the probable necessity of a surgical management.

          Optic disc pit: a review.

          Since Wiethe first described the clinical presentation of two optic disc depressions in a 62-year-old woman in 1882, there have been many studies addressing what later become known as the "optic disc pit." The main complication of this condition, termed optic disc pit maculopathy, is associated with visual deterioration. Treatment of optic disc pit maculopathy remains challenging. Here we review the body of literature that documents the clinical findings, pathophysiology, histology, main complications, treatment options, special features and presentations, and differential diagnosis of optic disc pit. The source of the intraretinal fluid in optic disc pit maculopathy remains controversial. Four possible sources of this fluid have been proposed: fluid from the vitreous cavity; cerebrospinal fluid originating from the subarachnoid space; fluid from leaky blood vessels at the base of the pit; and fluid from the orbital space surrounding the dura. 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.

            Long-term visual outcome in patients with optic nerve pit and serous retinal detachment of the macula.

            Serous detachment of the macula is a well-known complication in patients with an optic nerve pit. Despite the many descriptions of this condition and possible treatment options, the long-term natural history is not well known. The authors identified 15 eyes of 15 consecutive patients seen over 21 years who were diagnosed with a serous detachment of the macula arising from an optic nerve pit. Average length of follow-up was 9 years. Twelve eyes lost three or more lines of vision, two eyes remained unchanged, and only one eye improved. All of the 12 eyes losing three or more lines of vision experienced this decrease within the first 6 months of follow-up. Although only two patients had a visual acuity of 20/200 or less initially, 12 of 15 patients had a visual acuity of 20/200 or less at the time of their last examination. The appearance of the macula at last examination included cystic changes of the neurosensory retina, full-thickness hole formation, retinal pigment epithelial mottling, and lamellar hole formation in the outer retinal layer. The long-term visual prognosis in patients with optic nerve pit and untreated serous retinal detachment of the macula is poor, and visual loss occurs within 6 months of the serous detachment.

              Congenital pits of the optic nerve head. II. Clinical studies in humans.

              The clinical characteristics of 75 eyes with congenital pits of the optic nerve head were reviewed, particularly in relation to associated serous retinal detachment. Retinal detachment was found in 52% of all eyes with pits and 63% of eyes with temporally located pits. Of 20 untreated eyes with a pit and coexistent macular retinal detachment followed for more than one year, 55% (11/20) had visual acuity less than or equal to 6/30 and 75% (15/20) had subretinal fluid at the most recent visit. Visual fields and intravenous fluorescein angiographic characteristics of pits are discussed and clinical evidence is presented supporting the theory that the associated subretinal fluid is derived from liquified vitreous.
