urpose: To present external eye findings and the observation of irisatrophy in patients with climatic droplet keratopathy (CDK).Methods: Twenty-three patients with CDK and 13 controls living ina semideserted plain of the Argentine Patagonia were studied.Besides a comprehensive eye examination, Cochet-Bonnet aesthesiometry,Schirmer II test, breakup time (BUT), and surface stainingwere performed. According to corneal findings, eyes were grouped asgrade 1 (confluent translucent microdroplets localized in the limbicregion of the horizontal quadrants); grade 2 (band-shaped subepithelialhaziness compromising the central cornea); and grade 3(previously described lesions with yellow subepithelial droplets).Results were analyzed with the Fisher, Mann–Whitney, andSpearman tests, which were considered significant at P , 0.05.Results: Nineteen of 23 patients with CDK had bilateral disease,which was asymmetric in 2
