H18.551
Macular corneal dystrophy, right eye
Clinical Classification Guidelines
Medical Intelligence & Overview
Macular corneal dystrophy is a rare genetic eye disorder that affects the cornea, leading to clouding and vision problems. When it affects only the right eye, it is categorized under ICD-10 code H18.551. This condition causes abnormal deposits within the corneal tissue, resulting in progressive vision impairment. Understanding the nature of macular corneal dystrophy can help patients and caregivers better appreciate its impact and potential management options.
Causes & Symptoms
Clinical Causes: Genetic mutation inherited in an autosomal recessive pattern Abnormal accumulation of glycosaminoglycans within the stromal layer of the cornea Possible environmental factors that may influence disease progression are not well established
Key Symptoms: Progressive blurring of vision in the affected eye Corneal haze or cloudiness that may become more noticeable over time Sensitivity to light (photophobia) Decreased visual acuity that can affect daily activities Presence of faint or dense stromal deposits visible upon eye examination
Diagnostic & Treatment
Diagnosis Path: Diagnosis typically involves a comprehensive eye examination, including slit-lamp biomicroscopy to observe corneal changes. Corneal sampling or biopsy can reveal characteristic deposits of glycosaminoglycans. Genetic testing may be used to confirm inherited patterns. Differential diagnosis includes other corneal dystrophies such as Reis-Buecklers or lattice dystrophy. Imaging modalities like corneal pachymetry can assess corneal thickness and severity of clouding.
Treatment Protocols: Management of macular corneal dystrophy aims to improve vision and slow disease progression, although no cure exists. Treatment options include:
