Congenital Optic Nerve Anomalies and Associated Systemic Conditions

Le résumé fourni par la source

Congenital optic nerve anomalies represent a group of structural malformations that impair vision, increase the risk of ophthalmic complications, and are frequently associated with systemic conditions. We provide a review of major congenital optic disc anomalies, including optic nerve hypoplasia, morning glory disc anomaly, optic disc coloboma, peripapillary staphyloma, persistent fetal vasculature, myelinated nerve fibers, tilted disc syndrome, optic disc pit, papillorenal syndrome, optic disc drusen, and congenital optic disc pigmentation. We will review the definition, epidemiology, pathophysiology, clinical presentation, diagnostic workup, and associated systemic findings. An emphasis is placed on screening and multidisciplinary management aimed at correcting and preserving vision and preventing complications, such as retinal detachment, maculopathy, strabismus, amblyopia, and endocrine disorders. Diagnosis tools, including optical coherence tomography (OCT), B-scan ultrasonography, magnetic resonance imaging (MRI), and computed tomography (CT), are highlighted for their role in screening for these conditions. Many congenital optic nerve anomalies lack a definitive cure, and some conditions are extremely rare and do not have well-defined treatment protocols. However, routine ophthalmic examination, correction of refractive errors, visual surveillance for systemic conditions, and surgical intervention can optimize patient outcomes. Furthermore, multidisciplinary collaboration between ophthalmologists and other physicians, including pediatricians, endocrinologists, neurologists, and geneticists is often needed to facilitate care.
