Neuro Ophthalmology Glossary

Abnormal regrowth of damaged cranial nerve fibers, resulting in inappropriate innervation and paradoxical eye movements.

The involuntary convergence eye movement that accompanies accommodation when focusing on near objects.

Involuntary, sustained contraction of the ciliary muscle causing excessive focusing.

A condition where one pupil responds less to direct light than consensual light, indicating optic nerve damage.

Arteritic anterior ischemic optic neuropathy; vision-threatening condition associated with giant cell arteritis.

A group of inherited conditions causing reduced melanin production, resulting in characteristic ocular abnormalities inc...

Unequal pupil size that may be physiological or indicate neurological pathology affecting pupillary innervation.

Eye strain or visual fatigue characterized by discomfort, aching, or tiredness of the eyes, often associated with prolon...

The coordinated use of both eyes to create a single, unified visual perception with depth sensation and enhanced visual...

Branch retinal artery occlusion causing sectoral visual field defects.

Branch retinal vein occlusion causing retinal hemorrhages and potential vision loss.

Neurological condition affecting cranial nerves within the cavernous sinus, causing ophthalmoplegia, ptosis, and sensory...

The anatomical structure where optic nerve fibers partially cross, creating the basis for binocular visual field organiz...

Pattern of visual field defects caused by lesions at the optic chiasm, typically producing bitemporal hemianopia.

Bedside clinical assessment of visual field using finger counting or target detection.

Synchronized movement of both eyes in the same direction, controlled by brainstem gaze centers.

A binocular vision disorder where the eyes cannot converge adequately for comfortable near vision work.

Vision loss resulting from damage to visual cortex or visual processing areas while the eyes and optic nerves remain int...

Dysfunction of one or more cranial nerves controlling eye movement, often presenting with diplopia, ptosis, or pupillary...

Central retinal artery occlusion causing acute severe vision loss.

Central retinal vein occlusion causing retinal hemorrhages and vision loss.

Paralysis of the ciliary muscle resulting in loss of accommodation.

Double vision resulting from misalignment of the eyes or neurological dysfunction affecting eye movement.
