Viral keratitis and Unilateral Foreign Body Feeling

Viral Keratitis Overview

Viral keratitis is an inflammation of the cornea caused by viruses like herpes simplex virus (HSV), leading to potential vision impairment if untreated. It commonly presents with symptoms including eye pain, redness, blurred vision, light sensitivity, and watery discharge. This condition often recurs due to the virus remaining latent in the body after initial infection.

Unilateral Foreign Body Sensation

A unilateral foreign body sensation refers to a scratchy or gritty feeling in one eye, as if a particle is present, often stemming from corneal irritation or epithelial defects. This symptom can occur without an actual foreign object and is frequently linked to conditions like keratitis, where the cornea's nerve endings become exposed. Associated signs include tearing, redness, pain during blinking, and blurred vision in the affected eye only.

Connection Between Viral Keratitis and Foreign Body Feeling

In viral keratitis, the foreign body sensation arises from corneal epithelial damage or ulcers, mimicking the irritation of debris but caused by viral replication and inflammation. For instance, herpes simplex keratitis often features this unilateral discomfort alongside photophobia and discharge, distinguishing it from simple foreign body trauma. Prompt medical evaluation is crucial, as untreated cases can lead to scarring or vision loss.

When to Seek Care

Seek immediate Optometric or and  Ophthalmologic attention for unilateral foreign body sensation with redness or pain, especially if linked to recent viral symptoms or contact lens use, to rule out keratitis. Diagnosis typically involves slit-lamp examination and possible viral swabbing, with antiviral treatments like eye drops prescribed as needed. Early intervention prevents complications> DO NOT DELAY. SEEK MEDICAL HELP ASAP!!!
