H18.553
Macular corneal dystrophy, bilateral
Clinical Classification Guidelines
Medical Intelligence & Overview
Macular corneal dystrophy is a rare inherited eye disorder that affects the cornea, the clear front surface of the eye. This condition causes progressive deterioration of the corneal tissue, leading to blurred vision and discomfort. The disease typically affects both eyes (bilateral) and tends to develop gradually over time, impacting the clarity of vision and, if left untreated, may lead to significant visual impairment.
Causes & Symptoms
Clinical Causes: Genetic mutations inherited in an autosomal recessive pattern Defects in the carbohydrate and keratan sulfate metabolism within the corneal tissue Presence of abnormal deposits in the cornea's stroma layer
Key Symptoms: Progressive blurring of vision Corneal haze or opacity Sensitivity to bright light Foreign body sensation or irritation in the eye Color changes or cloudiness in the cornea Potentially, episodes of pain or discomfort
Diagnostic & Treatment
Diagnosis Path: Diagnosis involves a comprehensive eye examination by an ophthalmologist, including slit-lamp biomicroscopy to observe corneal opacities, and special tests such as corneal topography and confocal microscopy. Genetic testing can also confirm the presence of specific mutations associated with macular corneal dystrophy. A detailed review of family health history is often conducted given its inherited nature.
Treatment Protocols: Corneal transplantation, such as a penetrating keratoplasty or lamellar keratoplasty, to replace the diseased corneal tissue Use of corrective visual aids like glasses or contact lenses to optimize vision Regular monitoring by an eye care professional to track disease progression Managing symptoms with lubricating eye drops or ointments if irritation occurs
