Ocular ischemia refers to a condition where there is insufficient blood flow to the eye, leading to damage of the ocular tissues. This reduced blood supply can result from various factors, including diabetes, hypertension, or arterial occlusion. Symptoms may include vision loss, eye pain, and changes in visual perception. The condition can affect different parts of the eye, such as the retina or optic nerve. Early diagnosis and treatment are crucial to prevent permanent vision loss. Management may involve addressing underlying health issues and improving blood circulation to the eye.
