H50.642
Lateral rectus muscle entrapment, left eye
Clinical Classification Guidelines
Medical Intelligence & Overview
Lateral rectus muscle entrapment occurs when the lateral rectus muscle, which controls the outward movement of the eye, becomes trapped or pinched due to trauma or injury. This condition affects eye movement, potentially leading to double vision or difficulty focusing. It is usually the result of orbital fractures or other injuries to the eye socket area.
Causes & Symptoms
Clinical Causes: Trauma or blunt injury to the eye or surrounding orbital bones Orbital fractures, especially to the lateral wall Accidental or sports-related injuries Surgical complications involving the eye or orbital region
Key Symptoms: Limited ability to move the affected eye outward Double vision, especially when looking toward the affected side Swelling and bruising around the eye Pain or discomfort in and around the eye Redness or tenderness in the orbital area Potential redness or limited eye movement on affected side
Diagnostic & Treatment
Diagnosis Path: Medical professionals typically perform a comprehensive eye examination to assess eye movement and alignment. Imaging techniques such as CT scans or MRI are often used to confirm the entrapment of the lateral rectus muscle and to evaluate the extent of orbital damage. The diagnosis hinges on identifying restricted eye movement and visual disturbances correlating with imaging results.
Treatment Protocols: Treatment options depend on the severity of the muscle entrapment. Mild cases may resolve with conservative measures such as rest, eye patching, or corticosteroids to reduce inflammation. In more significant cases, surgical intervention might be necessary to release the entrapped muscle and repair orbital fractures. Post-treatment rehabilitation can include eye exercises and follow-up assessments to restore normal eye movement.
