Schnyder corneal dystrophy — Definition
Schnyder kornea distrofisi / Schnyder corneal dystrophy
Schnyder corneal dystrophy is a rare genetic disease, characterized by the accumulation of crystal-like cholesterol in the cornea. Otozomal shows dominant inheritance and often occurs during childhood or early adulthood. The opacity and bright, needle-shaped crystals are formed in the stroma layer of the cornea, which can lead to a decrease in visual acuity. The disease is often not associated with systemic lipid metabolism disorders, but corneal findings are decisive for diagnosis.
Disease Definition
🔬 Disease Definition
Schnyder kornea distrofisi, korneada kristalize kolesterol birikimi ile karakterize, nadir görülen, otozomal dominant geçişli bir kornea distrofisidir.
🧬 Causes & Risk Factors
UBIAD1 genindeki mutasyonlar nedeniyle korneada kolesterol metabolizması bozulur.
🩺 Symptoms & Signs
Korneada kristalize kolesterol birikintileri, korneal opasite, görme keskinliğinde azalma, fotofobi, bazen ağrı.
📋 Diagnostic Methods
Klinik muayene (yarık lamba biyomikroskopi), aile öyküsü, genetik testler (UBIAD1 mutasyon analizi).
💊 Treatment Options
Semptomatik tedavi (yapay gözyaşı, fotofobi için güneş gözlüğü), ilerlemiş vakalarda penetran keratoplasti veya fototerapötik keratektomi.
⚠️ Complications
Görme kaybı, korneal ülserasyon, sekonder enfeksiyon, greft reddi (cerrahi sonrası).
