Bilateral, anterior stromal ring opacity of the cornea.
AIMS/BACKGROUND To describe a bilateral, mid peripheral, ring-shaped corneal opacity, not resembling any known corneal degeneration, dystrophy, or other disorder, and occurring without ocular or systemic disease. METHODS Ophthalmic examination, haematological screening, and ultrasound biomicroscopy. RESULTS A 25 year old man showed grey-white, granular opacities in both corneas, with an 8 m...

متن کاملCorneal Biomechanics in Ectatic Diseases: Refractive Surgery Implications
BACKGROUND Ectasia development occurs due to a chronic corneal biomechanical decompensation or weakness, resulting in stromal thinning and corneal protrusion. This leads to corneal steepening, increase in astigmatism, and irregularity. In corneal refractive surgery, the detection of mild forms of ectasia pre-operatively is essential to avoid post-operative progressive ectasia, which also depend...
