Corneal diseases refer to various 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 corneal diseases include keratitis, which is inflammation of the cornea, and corneal dystrophies, which are genetic disorders that cause clouding of the cornea. Treatment for corneal diseases varies depending on the specific condition. Options may include medications, such as antibiotics or anti-inflammatory drugs, and in more severe cases, surgical procedures like corneal transplants may be necessary to restore vision and alleviate symptoms.
