Strabismus

Strabismus is a clinical condition characterized by the ocular misalignment of the visual axes, where the eyes do not point at the same object simultaneously. This misalignment disrupts binocular vision, potentially leading to amblyopia (lazy eye) and impaired depth perception.

Etiology involves disruption of the binocular coordination centers in the brain or mechanical dysfunction of extraocular muscles. Causes include neurological disorders (cerebral palsy, hydrocephalus), trauma, uncorrected refractive errors (hyperopia), and genetic predispositions involving familial patterns of ocular muscle control.

Pathophysiology involves a failure of the cortical mechanisms (vergence) to maintain ocular alignment. This may arise from primary muscle weakness or, more commonly, dysfunction in the cranial nerves (III, IV, VI) or the supranuclear pathways. If onset occurs during the critical period of visual development, the brain suppresses input from the misaligned eye, leading to irreversible amblyopia.

Strabismus affects approximately 2% to 4% of the global population. Onset is most common in early childhood (infantile or accommodative esotropia), though secondary strabismus can develop at any age due to neurological injury or orbital disease.

• Family history of strabismus
• Low birth weight or prematurity
• Refractive errors (high hyperopia)
• Chromosomal abnormalities (Down Syndrome)
• Congenital neurological disorders

A. Early Symptoms

• Intermittent ocular deviation


• Frequent rubbing of eyes


• Squinting in sunlight B. Common Symptoms


• Constant misalignment


• Diplopia (double vision)


• Tilting of the head to maintain focus C. Advanced Symptoms


• Permanent loss of stereopsis (depth perception)


• Significant visual acuity reduction (Amblyopia) D. Emergency Symptoms


• Sudden-onset double vision in adults (possible cranial nerve palsy/aneurysm)


• Complete ophthalmoplegia

Inspection reveals ocular deviation. The Hirschberg test (corneal light reflex) shows asymmetric light reflection. The cover-uncover test demonstrates the shift of the fixating eye when the deviating eye is covered.

A. Clinical Assessment: Cover-uncover test, Hirschberg test, Krimsky test.
B. Laboratory Testing: Rarely required unless systemic disease suspected.
C. Imaging Studies: MRI/CT if secondary to orbital or CNS mass.
D. Functional Tests: Stereopsis testing, binocularity assessment.
E. Biopsy Findings: Not indicated.
F. Genetic Testing: Only for syndromic cases.
G. Differential Diagnosis: Pseudostrabismus (epicanthal folds).

Test Name: Thyroid Stimulating Hormone (TSH)
Type: Blood Test
Purpose: Rule out Graves' Ophthalmopathy
Expected Findings: Normal
Interpretation: Abnormal suggests thyroid-associated orbitopathy causing mechanical deviation.

• MRI Brain/Orbits: Used when non-comitant strabismus or cranial nerve palsy is suspected. Detects masses or demyelinating lesions.

• Pseudostrabismus (normal appearance mimicking strabismus)
• Duane Retraction Syndrome
• Brown Syndrome

• Amblyopia, diplopia, social anxiety, loss of depth perception.

A. Lifestyle Modifications: Patching or blurring the "good" eye.
B. Preventive Measures: Early vision screening.
C. Medical Treatment: - Miotic agents (for accommodative esotropia) - Botulinum toxin (chemodenervation of muscle)
D. Surgical Treatment: Recession or resection of extraocular muscles.
E. Interventional Procedures: Prismatic glasses.
F. Rehabilitation: Orthoptic vision therapy.
G. Emergency Management: Evaluation for neurosurgical causes if acute.

Generally good with early intervention. Untreated childhood cases often result in permanent amblyopia.

Early childhood vision screening (ages 3–5).
