- Calcific degeneration (Band Shape keratopathy)
- a degenerative change associated with deposition of calcium salts in
- Bowman’s membrane
- most superficial part of stroma
- in deeper layers of epithelium.
- Band keratopathy is seen in association with
- chronic uveitis in adults
- children with Still’s disease
- phthisis bulbi
- chronic glaucoma
- chronic keratitis
- ocular trauma.
- Age related BSK is common and affects otherwise healthy cornea.
- Metabolic conditions rarely associated with BSK include
- hypercalcaemia (MCQ)
- chronic renal failure.
- Clinical features.
- It typically presents as a band- shaped opacity in the interpalpebral zone with a clear interval between the ends of the band and the limbus (MCQ)
- The condition begins at the periphery and gradually progresses towards the centre.
- The opacity is beneath the epithelium which usually remains intact.
- Surface of this opaque band is stippled due to holes in the calcium plaques in the area of nerve canals of Bowman’s membrane
- Chelation with EDTA (chelating agent)
- Phototherapeutic keratectomy (PTK) with excimer laser is very effective
- Keratoplasty may be performed when the band keratopathy is obscuring useful vision.
