H18.712

Clinical Causes: Previous eye surgeries, particularly corneal refractive surgeries like LASIK Genetic predisposition or family history of corneal disorders Keratoconus, a condition where the cornea thins and bulges outward, can lead to ectasia Trauma or injury to the eye Certain systemic conditions affecting connective tissue Progression from corneal thinning disorders

Key Symptoms: Blurry or distorted vision Increased sensitivity to light and glare Halos or starbursts around lights Sudden or gradual decrease in visual acuity Feeling of eye pressure or discomfort Irregular astigmatism affecting vision clarity

Diagnosis Path: Diagnosis begins with a comprehensive eye examination, including detailed corneal imaging tests such as corneal topography and pachymetry. These tests measure the shape and thickness of the cornea, helping eye specialists identify abnormal bulging or thinning. Additional assessments like slit-lamp examinations aid in visualizing corneal changes. Sometimes, patients may undergo corneal tomography to analyze the corneal structure in three dimensions. A detailed patient history is also considered, especially if there’s prior eye surgery or family history of corneal conditions.

Treatment Protocols: Eyeglasses or soft contact lenses to improve vision in early stages Rigid gas-permeable contact lenses or scleral lenses to correct irregular astigmatism Corneal collagen cross-linking (CXL): A minimally invasive procedure that strengthens corneal tissue using riboflavin (vitamin B2) and ultraviolet light, halting disease progression Custom or hybrid contact lenses for advanced cases Intacs implants: Small ring segments inserted into the cornea to flatten the bulging area Corneal transplant: In severe cases, a full or partial-thickness corneal transplant may be necessary to restore corneal integrity and vision Ongoing monitoring: Regular check-ups to track changes and adjust treatment as needed
