H18.891

Clinical Causes: Infections: Bacterial, viral, or fungal infections that damage corneal tissue Trauma: Physical injuries to the eye resulting in corneal damage Keratitis: Inflammation of the cornea due to various causes Degenerative Conditions: Conditions like keratoconus that cause thinning and bulging of the cornea Corneal Dystrophies: Genetic disorders leading to abnormal deposits in the cornea Exposure to harsh environmental factors: UV rays, chemicals, or dust Post-surgical complications: After procedures like LASIK or corneal transplant Autoimmune diseases: Conditions such as rheumatoid arthritis that affect eye tissue Nutritional deficiencies: Lack of vital nutrients like vitamin A that impact corneal health

Key Symptoms: Blurred or hazy vision Sensitivity to light (photophobia) Eye redness and irritation Feeling of grittiness or foreign body sensation Pain or discomfort in the eye Decreased visual acuity Tearing or watery eyes Appearance of corneal opacities or scars

Diagnosis Path: Diagnosis typically involves a thorough eye examination by an ophthalmologist, including slit-lamp biomicroscopy to scrutinize the cornea’s structure. Additional tests may include corneal topography to map the surface of the eye, fluorescein staining to detect corneal epithelial defects, and anterior segment optical coherence tomography (AS-OCT) to obtain detailed images of corneal layers. A detailed medical history, including any recent injuries, surgeries, or infections, is also essential for accurate diagnosis.

Treatment Protocols: Medications: Antibiotic, antifungal, or antiviral eye drops for infections; anti-inflammatory drugs for inflammatory conditions Protective measures: Use of sunglasses, eye shields, or avoiding environmental irritants Corneal debridement: Removal of damaged tissue or deposits from the corneal surface Contact lens use: Special lenses like scleral lenses to protect or improve vision Surgical interventions: Procedures like corneal transplantation (keratoplasty) or lamellar keratoplasty for severe cases Management of underlying conditions: Treating autoimmune or systemic diseases contributing to the corneal disorder Regular follow-up: Monitoring to assess response to treatment and prevent progression
