H18.54
Lattice corneal dystrophy
Clinical Classification Guidelines
Medical Intelligence & Overview
Lattice corneal dystrophy is a hereditary eye condition that affects the cornea, the clear front surface of the eye. Characterized by the buildup of abnormal protein deposits, this disease leads to the formation of lattice-like patterns on the cornea, resulting in visual disturbances and potential complications if left untreated. It is classified under ICD-10 code H18.54 and typically manifests in early to middle adulthood, although symptoms can vary widely among individuals. Managing this condition often involves regular eye examinations to monitor progression and to determine appropriate treatment options, which may include medical or surgical interventions.
Causes & Symptoms
Clinical Causes: Genetic mutations, predominantly inherited in an autosomal dominant pattern, leading to abnormal protein accumulation in the cornea. Presence of specific gene mutations affecting the collagen or other structural proteins within the corneal stroma.
Key Symptoms: Blurred or distorted vision that gradually worsens over time. Recurring episodes of eye discomfort, dryness, or irritation. Presence of lattice-like opacities or stromal deposits visible upon eye examination. Increased light sensitivity and glare, especially during nighttime. Potential for recurrent corneal erosions, causing pain and tearing. Progressive thickening or scarring of the cornea in advanced stages.
Diagnostic & Treatment
Diagnosis Path: Diagnosis of lattice corneal dystrophy involves a comprehensive eye examination, including slit-lamp biomicroscopy, which can reveal characteristic lattice-like opacities in the corneal stroma. An ophthalmologist may perform additional imaging techniques such as corneal topography or confocal microscopy to assess the extent of corneal involvement. Family history is also considered, given the hereditary nature of the disease. In some cases, genetic testing for mutations associated with the disorder can further confirm the diagnosis.
Treatment Protocols: Use of topical lubricants and steroid eye drops to alleviate discomfort and inflammation. Regular monitoring of corneal changes through scheduled eye exams to assess disease progression. Corneal transplantation procedures, such as penetrating keratoplasty or lamellar keratoplasty, may be recommended when vision is significantly impaired or corneal scarring becomes dense. Phototherapeutic keratectomy (PTK), a laser treatment that can remove superficial corneal deposits and improve visual acuity. Genetic counseling for affected individuals and their families to understand inheritance patterns and risks.
