Bilateral Optic Disc Drusen in an Adolescent Female: A Case Report

Abstract

Abstract Optic disc drusen (ODD) are calcified deposits within the optic nerve head, usually buried and uncalcified in young patients, and present as pseudopapilloedema, therefore, posing a diagnostic challenge. This case report describes the case of a 15-year-old girl who presented with bilateral ocular discomfort and left eyelid twitching of about eight months' duration. Presenting visual acuity was 6/5 in each eye. The remarkable finding was bilateral elevated optic discs with indistinct disc boundaries and cup-to-disc ratios of 0.1 on dilated examination. A clinical diagnosis of pseudopapilloedema secondary to disc drusen was made. A B-scan ultrasound, Humphrey central visual field and optical coherence tomography supported the clinical diagnosis of optic drusen, and the patient and caregivers were counselled appropriately while adopting a conservative management. This case report highlights the importance of considering ODD in the differential diagnosis of blurred disc margins with preserved visual function in paediatric patients and demonstrates the diagnostic value of B-scan ultrasonography for detecting buried drusen when advanced imaging is unavailable.
