H16.121
Filamentary keratitis, right eye
Clinical Classification Guidelines
Medical Intelligence & Overview
Filamentary keratitis is a condition affecting the cornea, the clear front surface of the eye. It involves the formation of fine, filament-like strands on the corneal surface, which can cause discomfort and visual disturbances. When this condition affects the right eye specifically, it is classified under ICD-10 code H16.121. The condition can vary in severity and may be linked to other eye conditions or environmental factors. Recognizing the symptoms and understanding the causes can help in managing the condition effectively.
Causes & Symptoms
Clinical Causes: Chronic dry eye syndrome Ocular surface infections Corneal epithelial defects or trauma Inflammatory eye conditions such as blepharitis Exposure to environmental irritants like wind, smoke, or dust Previous eye surgeries or injuries Certain autoimmune diseases affecting the eyes Use of contact lenses over prolonged periods
Key Symptoms: Persistent foreign body sensation Redness and irritation of the affected eye Tearing or watery eyes Blurred vision or light sensitivity Scratching or gritty feeling in the eye Presence of filament-like strands on the corneal surface Mild to moderate eye discomfort which may increase in bright or windy conditions
Diagnostic & Treatment
Diagnosis Path: To diagnose filamentary keratitis, an eye care professional conducts a comprehensive eye examination, including slit-lamp microscopy, which allows detailed visualization of the corneal surface. During this examination, the filaments can be identified as fine, thread-like structures adhering to the cornea. The clinician may also evaluate tear production and assess for underlying causes such as dry eye syndrome or ocular surface disease. Additional tests may include staining with fluorescein dye to highlight epithelial damage or defects.
Treatment Protocols: Managing filamentary keratitis typically involves a combination of measures aimed at eliminating the filaments, promoting corneal healing, and addressing underlying causes. Treatment options include:
