What is a common ocular symptom experienced by patients with Oculobular Myasthenia Gravis?

• A. Dysarthria
• B. Double vision
• C. Difficulty chewing
• D. Facial asymmetry

Answer: (B)

Patients with Oculobulbar Myasthenia Gravis often experience double vision, known as diplopia. This symptom arises due to the weakness of the extraocular muscles that are responsible for eye movement. In Myasthenia Gravis, an autoimmune response reduces the effectiveness of acetylcholine at the neuromuscular junction, which leads to muscle fatigue and weakness. The muscles controlling eye movement may be affected, resulting in the inability to properly align the eyes, causing double vision. While dysarthria, difficulty chewing, and facial asymmetry can also be associated with Oculobulbar Myasthenia Gravis due to the involvement of bulbar muscles, double vision is particularly characteristic and frequently reported in patients, making it a prominent ocular symptom in this condition.
