The influence of blood sugar level on visual functions and ocular surface changes in young adults with diabetes

The escalating prevalence of diabetics in the world and Malaysia particularly, is alarming. Among the complications of diabetes especially in the elderly patients, is retinopathy, which may derive from the affected posterior eye and influence the visual functions. However, limited studies investigat...

The original OSDI was translated and transformed into an online questionnaire using JotForm program and was distributed to 195 bilingual participants to assess its reliability.

The OSDI Bahasa Malaysia is reliable and repeatable.

Contrast sensitivity is sensitive in the early ocular changes in young adult diabetics.
