Superficial punctate keratitis is a medical term used to describe a specific type of inflammation occurring on the surface of the cornea. The cornea is the clear and transparent front part of the eye that covers the iris and pupil.
In superficial punctate keratitis, tiny, pinpoint-sized lesions or abrasions develop on the cornea, resulting in its inflammation. These lesions are usually superficial in nature, meaning they affect only the outermost layer of the cornea, known as the epithelium. As a result, this condition is often referred to as punctate epithelial keratitis.
Superficial punctate keratitis can be caused by various factors, including damage from foreign bodies, exposure to intense ultraviolet light or radiation, severe dry eye syndrome, allergies, infections, or as a side effect of certain medications. Other underlying conditions, such as autoimmune diseases or systemic infections, might also contribute to the development of this condition.
Symptoms of superficial punctate keratitis typically include eye redness, pain, discomfort, and a gritty or sandy feeling in the eye. In some cases, individuals may also experience blurry vision or increased sensitivity to light.
Treatment for superficial punctate keratitis primarily focuses on addressing the underlying cause, if possible, and relieving the symptoms. This can involve the use of lubricating eye drops, antibiotics or antiviral medications, anti-inflammatory drugs, or specialized contact lenses. In severe or chronic cases, additional medical interventions, such as corticosteroid eye drops or surgical procedures, might be necessary.
