Risk factor analysis and clinical decision tree model construction for diabetic retinopathy in Western China.

Background: Diabetic retinopathy (DR) is the driving force of blindness in patients with type 2 diabetes mellitus (T2DM). DR has a high prevalence and lacks effective therapeutic strategies, underscoring the need for early prevention and treatment. Yunnan province, located in the southwest plateau of China, has a high pre-valence of DR and an underdeveloped economy.

Mitochondrial transfer RNA variants and primary congenital glaucoma.

Variants in mitochondrial DNA (mtDNA) are the most important causes for vision loss, the mt-tRNA variants being the largest group among them. In this study, we report the molecular characterization of 15 mt-tRNA variants with primary congenital glaucoma (PCG). Based on phylogenetic approach, we found that only half of them were definitely pathogenic with PCG, other mutations were single nucleotide polymorphisms (SNP) in human population.
