H50.659
Medial rectus muscle entrapment, unspecified eye
Clinical Classification Guidelines
Medical Intelligence & Overview
Medial rectus muscle entrapment involves the trapping or restriction of the medial rectus muscle, one of the six muscles that control eye movement. This condition affects eye mobility and alignment, often resulting from trauma or certain medical conditions. It can cause symptoms related to impaired eye movement and double vision, impacting daily activities and eye comfort.
Causes & Symptoms
Clinical Causes: Facial or orbital fractures, especially involving the medial wall or floor of the orbit. Orbital trauma from accidents or injuries causing swelling or displacement of eye tissues. Blunt injuries to the eye or surrounding structures. Surgical complications involving the eye or orbit. Tumors or growths within the orbit that lead to muscle entrapment.
Key Symptoms: Limited or restricted movement of the affected eye, especially when looking inward. Horizontal double vision, particularly when trying to look toward the side of the affected muscle. Eye pain or discomfort, especially with eye movement. Swelling or bruising around the affected eye. Possible redness or increased tearing. Misalignment of the eyes, leading to cosmetic concerns or visual confusion.
Diagnostic & Treatment
Diagnosis Path: Diagnosis involves a comprehensive eye examination by an eye care professional, during which they assess eye movements and alignment. Imaging studies like CT scans or MRI are often utilized to visualize orbital bones and soft tissues, confirming muscle entrapment and ruling out other issues such as fractures or tumors.
Treatment Protocols: Observation for minor cases where symptoms are mild and improving. Medications such as corticosteroids to reduce swelling and inflammation. Surgical intervention to release or reposition the entrapped muscle, especially in persistent or severe cases. Management of associated injuries or fractures to ensure proper healing and prevent further complications. Follow-up care with an eye specialist to monitor recovery and eye function.
