Double Optic Disc Pit With Retinal Pigmentation in a Woman With High Myopia

To identify the key insights or developments described in this article
1 Credit CME

A 37-year-old woman with high myopia presented for a routine ocular checkup visit. Her refractive error was −10.00 diopters (D) OD, −7.75 D OS, and best-corrected visual acuity was 20/20 OU. Her axial length (IOL Master [Zeiss]) was 27.27 mm in the right eye and 26.01 mm in the left eye. Intraocular pressure and anterior segment examination were normal. Fundus examination revealed an enlarged optic disc with 2 optic disc pits (ODPs) in the left eye, located at the nasal and inferotemporal rim (Figure, A, black arrowheads). Two areas of retinal pigmentation adjacent to the pits were noted. B-scan swept-source optical coherence tomography imaging revealed 2 distinct excavations of the optic disc (Figure, B, yellow arrowheads). Visual field test of the left eye showed an enlarged blind spot and a localized temporal defect, correlating with the pigmented areas nasal to the disc. Patients with ODPs are usually asymptomatic unless they develop maculopathy.1,2 This patient’s fundus examination and visual field test remained unchanged over a 1.5-year period of follow-up.
