The present disclosure provides a method for detecting corneal dystrophy in a subject, comprising a reaction mixture, the reaction mixture comprising one or more labeled probes comprising a mutant TGFBI nucleotide sequence; the reaction mixture further comprises at least one amplification primer pair for amplifying a TGFBI gene sequence from a biological sample from the subject; and detecting one, two, three, four, five or six mutations selected from the group consisting of G623D, M502V, R124S, A546D, H572R, and H626R mutations in TGFBI gene, wherein the detecting comprises detecting the one or more mutations using the labeled detection probes. Further provided is a reaction kit comprising the reaction mixture.
