Re: Nannini et al.: African ancestry is associated with higher intraocular pressure in Latinos (Ophthalmology 2016;123:102-8)

Nannini et al examined the relationship between African ancestry, as estimated from 5000 autosomal single nucleotide polymorphisms using a Bayesian factor analysis, and intraocular pressure in a population of 3541 Hispanics from Los Angeles.1 They expressed the hope that an understanding of the relationship between genetic ancestry and intraocular pressure in Latinos may help to elucidate racial differences and identify public health strategies to prevent and forestall the development of glaucoma.
