78 Possible Causes for Anisocoria, Horizontal Nystagmus

  • Triple A Syndrome

    […] severity of neurologic and autonomic dysfunction in Triple-A syndrome is quite variable, including hyperreflexia, impaired visual evoked potentials, optic nerve atrophy, anisocoria[] Eye movements were saccadic with horizontal gaze nystagmus. Pupils were bilaterally dilated, with poor response to direct light and accommodation.[] […] los casos diagnosticados de novo en los adultos en quienes predominan síntomas autonómicos y manifestaciones neurológicas como retardo mental, hiperreflexia, voz nasal, anisocoria[]

  • Brain Stem Herniation

    […] functional states of the vestibular system and may combine a rotational component with vertical or horizontal eye movements and may be spontaneous , positional , or evoked[] . opsoclonus refers to uncontrolled eye movement. opsoclonus consists of rapid, involuntary, multifactorial (horizontal and vertical), unpredictable, conjugate fast eye movements[] […] there are different kind of nystagmus depending on influence whether alcohol, injury, tumor, bleed or virus. peripheral nystagmus occurs as a result of either normal or diseased[]

  • Abnormal Eye Movement

    Approximately 25% of individuals have asymmetric pupils (anisocoria), with a difference of usually less than 0.5 mm in diameter.[] These acquired types include: Downbeat nystagmus Upbeat nystagmus Horizontal nystagmus Torsional nystagmus Pendular nystagmus Seesaw nystagmus Vestibular nystagmus Gaze-evoked[] Video Nystagmus During Visual Fixation and Head Thrust Test. (00:28) Acute unilateral loss of peripheral vestibular function causes spontaneous nystagmus that is horizontal[]

  • Infantile Periodic Alternating Nystagmus

    Other possible ocular signs are sluggish pupillary reaction to light, anisocoria, and optic disc edema (17).[] […] with nystagmus block Fatigable positional nystagmus Fixation nystagmus Heartbeat nystagmus Horizontal nystagmus Infantile nystagmus syndrome Jerk nystagmus Manifest nystagmus[] Periodic alternating nystagmus (PAN) is a rare horizontal nystagmus that periodically reverses its direction, usually about every 2 minutes. 1 Acquired PAN has been reported[]

  • Ptosis - Strabismus - Ectopic Pupils Syndrome

    Anisocoria that is NOT associated with or due to an underlying medical condition is called physiologic anisocoria.[] Some affected individuals may have strabismus or nystagmus.[] A rombinedjerk and pendular horizontal nystagmus was present.[]

  • Wernicke Encephalopathy

    […] commonly CN VI palsy nystagmus ataxic gait with associated features including: peripheral neuropathy resting tachycardia nutritional deficiency sluggish pupillary reflexes Anisocoria[] Examination revealed counting fingers acuity in both eyes with central scotomas, color vision loss, horizontal nystagmus, and gait ataxia.[] Less frequently noted manifestations are: pupillary abnormalities such as sluggishly reactive pupils, ptosis, scotomata, and anisocoria.[]

  • Ophthalmoplegia

    Anisocoria, Physiologic (Anisocoria) Anisometropia Anisometropic Amblyopia (Amblyopia) Anophthalmia (Anophthalmos) Anophthalmos Anterior Ischemic Optic Neuropathy (Optic[] Internuclear ophthalmoplegia (INO) describes a clinical syndrome of impaired adduction in one eye with dissociated horizontal nystagmus of the other abducting eye, due to[] There was no ptosis, anisocoria, or skew deviation, and the eye movement disorder was consistent with bilateral INO. The INO improved over the next year.[]

  • Diabetic Ophthalmoplegia

    Ophthalmoplegia reversed much earlier and more significantly when compared to anisocoria.[] EOM evaluation revealed a cyclorotational nystagmus with paralysis of nasal eye movement OD and an exotropia with an upbeat/horizontal nystagmus OS.[] It is characterized by a limited adduction by the eye on the same side of the body as the lesion, and a jerky, horizontal nystagmus and overshoot by the other eye on abduction[]

  • Wernicke-Korsakoff Syndrome

    Wernicke’s encephalopathy symptoms include: Vision impairment Sluggish pupil reflexes Uneven pupil size (anisocoria) Involuntary eye movement (nystagmus) Eye paralysis (ophthalmoplegia[] On exam, he appears inattentive, has bilateral horizontal nystagmus, and his gait is slow and wide-based.[] Wernicke’s Encephalopathy Nystagmus or the involuntary movement of the eye Anisocoria or the unequal pupil size Ataxia or the lack of coordination Pupillary reflexes that[]

  • Ocular Palsy

    Oculomotor palsies can also cause ptosis and anisocoria. An overview of cranial nerve anatomy is provided in Figure 9–1 .[] The most common pathological types of central nystagmus are downbeat nystagmus (DBN) and upbeat nystagmus (UBN).[] Anisocoria, Physiologic (Anisocoria) Anisometropia Anisometropic Amblyopia (Amblyopia) Anophthalmia (Anophthalmos) Anophthalmos Anterior Ischemic Optic Neuropathy (Optic[]
