Association between the G/G genotype of the lncRNA rs7158663 polymorphism and proliferative diabetic retinopathy.

Objective: To investigate the association between the long noncoding RNAs (lncRNAs) () rs7158663 polymorphism and diabetic retinopathy (DR) in patients with type 2 diabetes mellitus (T2DM).

Subjects And Methods: The study included 628 patients with T2DM and DR ("case group," including 283 with proliferative DR [PDR] and 345 with nonproliferative DR [NPDR]), and 381 patients with T2DM but no DR ("control group"). The diagnosis of DR was established using indirect ophthalmoscopy.
