Eye complications refer to various issues that can affect vision and overall eye health. Common complications include cataracts, which cloud the lens of the eye, and glaucoma, a condition that damages the optic nerve often due to high eye pressure. Other complications may arise from diabetes, leading to diabetic retinopathy, where blood vessels in the retina are damaged. Infections, such as conjunctivitis or keratitis, can also cause significant discomfort and vision problems. Additionally, injuries to the eye can result in complications like corneal abrasions or retinal detachment. Early detection and treatment are crucial to prevent permanent damage.
