Corneal disease refers to a range of conditions that affect the cornea, the clear front part of the eye. These diseases can lead to symptoms such as blurred vision, pain, and sensitivity to light. Common types include keratitis, which is inflammation of the cornea, and corneal dystrophies, which are genetic disorders that cause changes in the cornea's structure. Treatment for corneal disease varies depending on the specific condition. Options may include medications like antibiotics or anti-inflammatory drugs, contact lenses to improve vision, or surgical procedures such as corneal transplants to replace damaged tissue. Early diagnosis and management are crucial for preserving vision.
