When all else fails: Tectonic keratoplasty with silica gel re-dried cornea in a patient with high risk of corneal perforation.

Angioid streaks are linear dehiscences in the Bruch’s membrane, which may be idiopathic or associated with diseases based on an alteration of collagen, such as pseudoxanthoma elasticum or Paget’s disease.3 Therefore, we suggest that the angioid streaks could be associated with the AS, of which the physiopatholgical basis is an alteration of collagen type IV, a main component of all membranes in the body and, therefore, of Bruch’s membrane. Finally, we conclude that the high-resolution spectral domain OTC allows analysis of the microstructure of the layers of the retina, detecting incipient changes prior to viewing on fundoscopy. In this way, we are able to characterise new findings and establish an anatomic-functional correlation that justifies the visual impairment.
