Study Notes
Optic Nerve Disorders
-
Leber's disease: Characterized by spontaneous recovery of vision. A mitochondrial disorder affecting the optic nerve. Can sometimes mimic pseudo-optic nerve edema.
-
Optic neuritis: A condition causing pain with eye movement.
-
AION (Anterior Ischemic Optic Neuropathy): An optic condition needing immediate medical attention.
-
Papilledema: Associated with malignant hypertension and requires careful monitoring due to increased intracranial pressure (e.g., from venous thrombosis).
-
Von Hippel-Lindau syndrome: A condition affecting the eyes, where a feature is capillary hemangioma.
-
Optic nerve hypoplasia: The most common congenital optic nerve disorder. It can present with a double ring sign and strabismus.
-
Disc drusen: Composed of protein and calcium salts.
-
Optic nerve sheath meningioma: A slower-proceeding optic nerve tumor compared to optic nerve glioma.
-
Dominant optic atrophy: A mitochondrial disorder involving optic atrophy.
-
Coloboma: A congenital condition that can be associated with a double optic disc.
-
Astrocytic hamartoma: An eye condition whose presence is suggested by ocular imaging (e.g., in tuberous sclerosis).
