H16.422
Pannus (corneal), left eye
Clinical Classification Guidelines
Medical Intelligence & Overview
Pannus is a medical condition involving abnormal blood vessel growth on the cornea, which can affect vision. When referred to as pannus in the left eye, it indicates that this complication is present specifically in the eye's left cornea. The condition may result from chronic eye irritation, infection, or inflammation, leading to redness, scarring, and potentially impaired vision if left untreated. Recognizing the underlying causes and symptoms is essential for managing and preventing further deterioration of eye health.
Causes & Symptoms
Clinical Causes: Chronic eye inflammation or irritation History of ocular surface infections Exposure to environmental irritants such as dust, smoke, or chemicals Eye trauma or injury Autoimmune conditions affecting the eye Prolonged use of contact lenses without proper hygiene Peripheral corneal degenerations
Key Symptoms: Redness in the affected eye Blurred or decreased vision Foreign body sensation or discomfort Tearing or watery eyes Sensitivity to light (photophobia) Presence of a cloudy or hazy corneal appearance Raised, vascularized area on the cornea
Diagnostic & Treatment
Diagnosis Path: Diagnosing pannus involves a comprehensive eye examination by an ophthalmologist. The clinician will inspect the cornea using slit-lamp microscopy to identify abnormal blood vessels and tissue growth. Additional tests such as fluorescein staining may be used to evaluate corneal surface integrity, and detailed medical history will help identify potential causative factors. Differential diagnoses include other corneal conditions like keratitis or scarring, which require distinct treatments.
Treatment Protocols: Management of pannus aims to reduce inflammation, prevent further vascularization, and preserve vision. Possible treatment options include:
