Band keratopathy

  • 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
    • Treatment
      • 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.
