Schnyder corneal dystrophy is a rare dominant disorder mostly reported in Western and occasionally Asian populations. This report documents the condition in an affected family from the historically isolated Arabian Peninsula. A child and her mother had central crystalline keratopathy consistent with Schnyder corneal dystrophy. Diagnostic UB1AD1 testing revealed a known point mutation (c.361C>T, p.L121F) in both individuals. Available asymptomatic family members had normal ophthalmic examinations and did not have the mutation. Blood lipid profiles for the two patients revealed mildly elevated total cholesterol and low-density lipoproteins. This report documents Schnyder corneal dystrophy on the Arabian Peninsula and further confirms its relationship with heterozygous UB1AD1 missense mutation.
