330 Ocular Manifestations of Congenital/Inherited DiseasesSteven Galetta, MDThis 21-year-old woman had a 2-year history of blurred vision. A computerized visual field demonstrated a temporal defect OS. MRI confirmed a chiasmal mass lesion. The pathology was consistent with hemangioblastoma. Further workup revealed retinal angiomas and multiple other hemangioblastomas of the...

337 Systemic Disorders With Optic Nerve and Retinal FindingsSteven Galetta, MDThis fondus image shows a white-centered hemorrhage in a leukemia patient with orbital aspergillosis.
338 Isolated Congenital Optic Disc AnomaliesThomas R. Wolf, MDAn 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...
339 Optic Disc Drusen With AutofluorescenceThomas R. Wolf, MDThis photograph of optic disc drusen demonstrates autoflourescence with flourescein barrier filters in place. Imaging: flourescein barrier filters.
340 Isolated Congenital Optic Disc AnomaliesThomas R. Wolf, MDBenign tumors of blood vessels (hemangiomas) may occur on the optic nerve and may mimic optic disc edema. Disease/Diagnosis: Optic Nerve Hemangioma.
341 Isolated Congenital Optic Disc AnomaliesThomas R. Wolf, MDPatients 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...
342 Isolated Congenital Optic Disc AnomaliesThomas R. Wolf, MDOptociliary 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 ...
343 Isolated Congenital Optic Disc AnomaliesThomas R. Wolf, MDThis optic disc displays multiple drusen. Note the pseudopapilledema here. One can differentiate this from true papilledema in that there is no obscuration of the vessel by the peripapillary nerve fiber layer as they cross the disc margin. This photograph was taken with barrier filters in place, but...
344 Isolated Congenital Optic Disc AnomaliesThomas R. Wolf, MDAn 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.
345 Optic Disc Drusen Visual FieldsThomas R. Wolf, MDThis is the visual field of patient with optic nerve drusen. Whereas they typically do not cause central field loss, optic disc drusen may cause nerve fiber bundle layer defects and, thus, peripheral field defects, including altitudinal defects (seen inferiorly in the left eye) or arcuate defects (s...
346 Retinal Coloboma Underneath a Relatively Normal Optic NerveThomas R. Wolf, MDOptic 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...
347 Isolated Congenital Optic Disc AnomaliesThomas R. Wolf, MDPatients 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.
348 Peripapillary StaphylomaThomas R. Wolf, MDPatients 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...
349 Motility DisturbancesThomas R. Wolf, MDThe patient is a 53-year-old man with diplopia from right oculomotor nerve palsy and left hemiparesis (Weber's syndrome), with associated left lung hilar mass. The spinal tap showed pleocytosis consistent with carcinomatous meningitis. This image demonstrates oculomotor nerve metastatic carcinomatos...
350 Ocular Manifestations of Congenital/Inherited DiseasesWilliam Fletcher Hoyt, MDTuberous sclerosis is an autosomal dominant phakomatosis characterized by astrocytic hamartomas of the retina or optic nerve, adenoma sebaceum of the face, periungual fibromas, and astrocytic hamartomas of the brain, with secondary seizures and mental retardation. Disease/Diagnosis: Tuberous Scleros...
