Introduction:

Moyamoya disease is a rare vascular disorder affecting the arteries in the brain. This article explores the ocular manifestations associated with Moyamoya disease, shedding light on their nature, effects on vision, and clinical significance.

Understanding Moyamoya Disease:

Moyamoya disease involves the narrowing of certain arteries at the base of the brain, leading to reduced blood flow and an increased risk of stroke.

Ocular Manifestations of Moyamoya Disease:

Several ocular manifestations may be linked to Moyamoya disease:

• Retinal Artery Occlusion: The reduced blood flow can affect retinal arteries, potentially leading to retinal artery occlusion and vision loss.
• Ocular Ischemic Syndrome: Insufficient blood supply to the eye structures may result in ocular ischemic syndrome, characterized by pain, decreased vision, and neovascularization.
• Retinal Hemorrhages: Fragile blood vessels due to vascular compromise can lead to retinal hemorrhages.

Impact on Vision and Quality of Life:

Ocular manifestations of Moyamoya disease can have a profound impact:

• Visual Impairment: Retinal artery occlusion and ischemia can cause significant visual impairment or blindness.
• Reduced Visual Field: Ocular ischemic syndrome can lead to peripheral visual field loss, affecting daily activities.

Diagnosis and Management:

Diagnosing and managing ocular manifestations of Moyamoya disease involve:

• Regular Eye Examinations: Regular eye check-ups can help identify early signs of retinal artery occlusion or other ocular complications.
• Retinal Imaging: Imaging techniques like fundus photography and angiography can reveal vascular abnormalities.
• Collaborative Approach: Ophthalmologists and neurologists work together to manage Moyamoya disease and associated ocular issues.

Preventive Measures:

Minimizing the risk of ocular complications includes:

• Blood Pressure Control: Maintaining optimal blood pressure can help preserve blood flow to the eyes.
• Timely Intervention: Early diagnosis and treatment of Moyamoya disease can reduce the risk of stroke and associated ocular issues.

Conclusion:

Moyamoya disease's impact extends to ocular manifestations that can significantly affect vision and quality of life. Close collaboration between healthcare professionals is crucial for the timely diagnosis, management, and prevention of ocular complications in individuals with Moyamoya disease.
