Optic disc pits are rare congenital abnormalities. They are unilateral in 85% of the affected individuals. Optic disc pits occurring in the highly myopic eyes of the older adults are supposed to be acquired due to mechanical expansion of the disc from the axial elongation. High myopia is also a well described association of the optic disc pits of the congenital nature. We present a rare case of bilateral congenital optic disc pits in a 15-year-old girl having anisometropic unilateral axial myopia and the emmetropia in the fellow eye. This unique combination of the findings of unilateral high myopia in a child with bilateral congenital optic disc pits, to the best of our knowledge has not been described in the literature earlier. Our case demonstrates a scenario where two different causative factors for the optic disc pits may be present concurrently in the same instance.
Patients with acute optic neuritis typically present with acute loss of vision. We describe a case of a young lady of 25 years of age with blurring of vision in the upper visual field of the right eye with otherwise intact visual acuity as the only presenting symptom. Although altitudinal visual field defect is not unknown to be associated with acute optic neuritis, it is generally considered a relatively uncommon occurrence. Our case illustrates an unusually unique occurrence of upper altitudinal visual field defect in association with unaffected visual acuity as the sole presenting symptom of acute idiopathic unilateral optic neuritis. When an altitudinal visual field defect is a presenting feature, besides the usual vascular and compressive causes, optic neuritis should be remembered in the list of differential diagnoses.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
