Optic Nerve Disorders — Pathway Conditions

Simulations of optic nerve and visual pathway conditions affecting field of vision, acuity, and color perception.

Featured

Optic Neuritis

Inflammatory demyelination of the optic nerve causing pain, vision loss, and color desaturation.

Simulate Optic Neuritis

Central vision loss
Color desaturation
Pain with eye movement

Scotoma

Localized area of reduced or absent vision within the visual field.

Simulate Scotoma

Central scotoma
Paracentral scotoma
Arc & ring scotoma

Bitemporal Hemianopia

Loss of the temporal visual fields in both eyes, typically from chiasmal compression.

Simulate Bitemporal

Bilateral temporal loss
Chiasmal lesion
Tunnel-like vision

Homonymous Hemianopia

Loss of the same half of the visual field in both eyes from post-chiasmal damage.

Simulate Homonymous

Left or right field loss
Stroke-related
Macular sparing

Papilledema

Optic disc swelling from raised intracranial pressure causing transient visual obscurations.

Simulate Papilledema

Transient obscurations
Enlarged blind spot
Peripheral constriction

Ischemic Optic Neuropathy

Acute optic nerve ischemia causing sudden, painless vision loss with altitudinal field defects.

Simulate ION

Altitudinal field loss
Sudden onset
Disc edema

Leber Hereditary Optic Neuropathy

Mitochondrial genetic disorder causing acute or subacute bilateral central vision loss.

Simulate LHON

Central scotoma
Bilateral involvement
Young adult onset

Toxic Optic Neuropathy

Optic nerve damage from toxic substances causing bilateral, symmetric vision loss.

Simulate Toxic ON

Cecocentral scotoma
Color vision loss
Bilateral symmetric

Cortical Visual Impairment

Vision loss from damage to the visual cortex or posterior visual pathways.

Simulate CVI

Variable vision
Complexity intolerance
Light gazing
