Symptoms of Brown Syndrome (Brown)

Right-sided Brown syndrome has the following symptoms.

The main symptoms of Brown's syndrome (Brown)

• Usually the correct primary position of the eyes.
• Limitation of eyeball elevation in adduction to the right and sometimes in the middle position.
• As a rule, normal elevation of the right eyeball in abduction.
• Hyperfunction of the superior oblique muscle is minimal or absent.
• Positive traction test for eyeball elevation in adduction.

Irregular symptoms of Brown Syndrome (Brown)

• Deviation downward in adduction.
• Hypotropy in the primary position.
• Abnormal position of the head with the inclination of the head in the same direction and the rise of the chin.

Classification of Brown Syndrome (Brown)

Congenital

• Idiopathic.
• Congenital click-syndrome with broken tendon of the upper oblique muscle through trochlea.

Acquired

• Iatrogenic injury of the trochlea or tendon of the superior oblique muscle.
• Inflammation of the tendon caused by rheumatoid arthritis, pancinusitis or scleritis.

Differential Diagnosis of Brown Syndrome (Brown)

1. Paralysis of the lower oblique muscle is characterized by a more pronounced vertical deflection in the primary position, A-pattern and negative traction test.
2. Monocular insufficiency of lifters is characterized by the impossibility of elevation of the eyeball in any position.

Treatment of Brown Syndrome (Brown)

Congenital cases usually do not require treatment. Indications for surgical treatment are hypotrophy in the primary position and / or forced position of the head. Weakening of the upper oblique muscle is recommended.

In the acquired cases, steroid therapy (orally or injection into the block area) can be effective along with the elimination of the cause.
