• Keratoconus progression in a 44yoMale and hidden change in 22y/o woman Description: We describe here 2 interesting and differ cases: first the keratoconus progression over the last four years in a 44-year-old gentleman, despite traditional belief in teaching that keratoconus stabilizes at 40! Eye rubbing is the incident factor here! The second case is a 22-year-old young lady who was evaluated last year with mild to moderate keratoconus and although vision and Scheimpflug tomography appeared to be stable today 13 months later, anterior segment OCT ( Optovue, Avanti) imaging reveals compelling progression of the disease that is currently masked by vivid epithelial remodeling!! underlining the importance of using epithelial mapping not only to screen for, but also to follow keratoconus: please watch!
