Straylight, lens yellowing and aberrations of eyes in Type 1 diabetes

Abstract

Straylight, lens yellowing and ocular aberrations were assessed in a group of people with type 1 diabetes and in an age matched control group. Most of the former had low levels of neuropathy. Relative to the control group, the type 1 diabetes group demonstrated greater straylight, greater lens yellowing, and differences in some higher-order aberration co-efficients without significant increase in root-mean-square higher-order aberrations. Differences between groups did not increase significantly with age. The results are similar to the findings for ocular biometry reported previously for this group of participants, and suggest that age-related changes in the optics of the eyes of people with well-controlled diabetes need not be accelerated.

Visual complications in diabetes mellitus: beyond retinopathy

“…Straylight as a function of age in people with and without Type 1 diabetes (reproduced from Adnan et al . ).…”

“…Increased straylight has been found even in people with reasonably well‐controlled diabetes [HbA 1c 62 mmol/mol (7.8%)] as compared with people without diabetes [HbA 1c 31 mmol/mol (5.0%)] (Fig. ).…”

“…It is responsible for disability glare while driving at night, perception of halos around bright lights, facial recognition problems, hazy vision and lowered contrast [50]. Increased straylight has been found even in people with reasonably well-controlled diabetes [HbA 1c 62 mmol/mol (7.8%)] as compared with people without diabetes [HbA 1c 31 mmol/mol (5.0%)] [51] (Fig. 3).…”

Lens Shape and Refractive Index Distribution in Type 1 Diabetes

“…1 We also considered the effects of type 1 diabetes on accommodation, 2 ocular straylight, and lens yellowing. 3 The diabetic participants in the study exhibited low levels of the classic triad of diabetes complications-neuropathy, retinopathy, and nephropathy. Differences between the diabetes group and an age-balanced control group indicated that diabetic eyes appeared as older versions of normal eyes.…”

Optical Quality and Intraocular Scattering in the Diabetic Eye without Diabetic Retinopathy

“…Even if they were not assessed in the present study, part of the differences between the two groups could be due to differences in higher-order aberrations. Indeed, Adnan et al 36 demonstrated that intraocular stray light, total horizontal coma, and total vertical coma were greater in subjects with type 1 diabetes mellitus than in controls. Shahidi et al 17 reported a greater amount of total high-order aberrations in subjects with diabetes than in controls.…”
