Pterygium is one of the most common ocular surface diseases, and characterized by inflammatory infiltrates, proliferation, fibrosis, angiogenesis, and extracellular matrix breakdown. We investigated the association of polymorphisms in the RHO genes RHOA, RHOB, RHOC, RHOD, and RND3 (RHOE). The results of this study demonstrate for the first time the association of RHO genes with the pterygium. We displayed that the RHO gene polymorphisms were significantly associated with pterygium in the Turkish population.
