Keratitis

Keratitis is an inflammation of the cornea, which is the eye's clear front layer. Infections, trauma, or environmental factors can trigger this condition. Bacteria, viruses (such as herpes simplex), fungi, and parasites such as Acanthamoeba are common causes of infectious keratitis, which can especially affect contact lens wearers. On the other hand, trauma, UV exposure, or an immune response can cause non-infectious keratitis.
Keratitis symptoms include eye redness, discomfort, sensitivity to light, blurred vision, and excessive tearing. Keratitis can lead to corneal ulcers, open sores that increase the risk of scarring and permanent vision loss. People who wear contact lenses or have frequent eye injuries are more susceptible, and poor lens cleanliness can exacerbate the illness.
The underlying cause determines the treatment for keratitis. Antibiotic drops normally treat bacterial infections, while antiviral or antifungal medicine treats viral and fungal infections. In cases of severe corneal damage, surgical intervention, such as a corneal transplant, may be required to restore vision. It is crucial to diagnose and treat keratitis promptly to prevent complications and uphold optimal eye health.
