H18.541

Clinical Causes: Genetic mutations inherited in an autosomal dominant pattern, often involving the TGFBI gene Presence of amyloid deposits formed due to abnormal protein folding within the corneal stroma Potential familial history indicating a hereditary component affecting the corneal clarity

Key Symptoms: Gradual decline in visual acuity, often noticeable over several years Blurred or hazy vision resulting from corneal opacity Recurrent episodes of ocular discomfort or foreign body sensation Presence of visual disturbances such as ghost images or light sensitivity Corneal scarring or haze observed during eye examinations

Diagnosis Path: Diagnosis of lattice corneal dystrophy involves a comprehensive eye examination, including slit-lamp microscopy to visualize corneal changes. In some cases, corneal photography or corneal topography may be used to assess the extent of deposits. Family history is also considered, and genetic testing for mutations in the TGFBI gene can support the diagnosis. Early recognition helps in planning appropriate management strategies to preserve vision.

Treatment Protocols: While there is no cure for lattice corneal dystrophy, various treatment options aim to alleviate symptoms and improve vision. These include: - **Corneal Transplantation:** Penetrating keratoplasty or lamellar keratoplasty to replace the diseased corneal layer - **Phototherapeutic Keratectomy (PTK):** Laser therapy to remove superficial deposits and reduce corneal haze - **Regular Monitoring:** Frequent eye exams to monitor disease progression - **Supportive Measures:** Use of ocular lubricants to ease discomfort and prevent dryness Consulting with an ophthalmologist experienced in corneal dystrophies is essential to determine the most suitable management plan for individual cases.
