126 Isolated Congenital Optic Disc AnomaliesAn optic pit is a small defect in the optic disc that may be asymptomatic in isolation. Patients may develop an associated serous detachment of the macula. The condition is usually unilateral but may be bilateral. A fluorescein angiogram may demonstrate the serous detachment, and laser photocoagulat...Optic Pit With Serous Macular Detachment
127 Isolated Congenital Optic Disc AnomaliesAn optic pit is a small defect in the optic disc that may be asymptomatic in isolation. The pit can be small or large, and central or peripheral. Disease/Diagnosis: Optic Pit.Optic Pit; Macular Detachment
128 Isolated Congenital Optic Disc AnomaliesOptociliary shunt vessels are venous collaterals that form in response to chronic venous obstruction, shunting the venous blood from the retinal circulation into the choroidal circulation. Although they may be congenital, they may occur in patients with chronic disc edema, following central retinal ...Optociliary Shunt Vessels
129 Isolated Congenital Optic Disc AnomaliesPatients with hypoplasia of the optic nerve may have normal or subnormal visual acuity or visual field. The condition may be unilateral or bilateral. Optic nerve hypoplasia is usually idiopathic, but maternal diabetes, or maternal use of anti-epileptic drugs or alcohol are predisposing factors. Opti...Optic Nerve Hypoplasia; Septo-Optic Dysplasia
130 Retinal Coloboma Underneath a Relatively Normal Optic NerveOptic nerve colobomas appear as enlarged, white optic discs that are deeply excavated, often with some sapring of the superior rim. They result from an abnormal fusion of the proximal embryonic fissure. Optic nerve colobomas occur unilaterally or bilaterally with a similar frequency and can result i...Optic Nerve Coloboma
131 Isolated Congenital Optic Disc AnomaliesPatients with midline closure defects may exhibit abnormalities in the optic nerve, choroid, retinal pigment epithelium or retina. Anterior closure defects may result in colobomas of the structures of the anterior segment, such as the iris. Disease/Diagnosis: Coloboma.Optic Nerve Coloboma
132 Peripapillary StaphylomaPatients with ectasia of the outer layers of the eye may exhibit a posterior protrusion that appears on funduscopy as an area of deep excavation of the retina (posterior staphyloma). When it occurs around the optic disc, as in this case, it is termed a peripapillary staphyloma. This may occur in ass...Staphyloma

134 Neuro-Ophthalmic Imaging-MRIAxial view of Arnold-Chiari malformation on a patient with downbeat nystagmus. Note the presence of the cerebellar tonsils posterior to the caudal medulla. In addition to downbeat nystagmus, Arnold-Chiari malformations can sometimes lead to increased intracranial pressure and papilledema.Arnold-Chiari Malformation; Chiari Malformation; Inferior Tonsillar Herniation; Downbeat Nystagmus
135 Neuro-Ophthalmic Imaging-MRISagittal view of Arnold-Chiari malformation on a patient with downbeat nystagmus. The compression of the cervicomedullary junction is clearly depicted in the sagittal view.Arnold-Chiari Malformation; Chiari Malformation; Inferior Tonsillar Herniation; Downbeat Nystagmus
