Background. Meibomian gland dysfunction (MGD) is a chronic, diffuse abnormality of the meibomian glands, commonly characterized by terminal duct obstruction and/or qualitative/quantitative changes in the glandular secretion. Diabetic polyneuropathy can be the reason of MGD. Purpose: to justify the need to improve the efficiency of diagnosis of the ocular surface pathology in patients with type 2 diabetes and diabetic polyneuropathy.
Materials and methods: standard ophthalmological examination, the Schirmer’s test before and 2 hours after compression the eyelids, the Norn’s test, OPI test, performance of squeezing secretions, IVAD, OSDI test, contact meibography with green filter. 72 patients with type 2 diabetes participated in the study. They were divided into 2 groups (group 1 – 36 patients without diabetic polyneuropathy, group 2 – 36 patients with diabetic polyneuropathy). Control group – 58 people without diabetes.
Results: The Schirmer’s test in patients of group 2 (5.98 ± 0.35 mm) was reduced by 2.3 times compared to the control group (13.92 ± 0.15 mm) (p<0.001). The Norn's test in patients of 2 group (4.47 ± 0.18 s) was below normal in 2,1 times less than in the control group (9.49 ± 0.16 s) (p<0.001). The OPI test score in group 2 patients was in 1,9 times lower than in the control group (p<0.001). The data of meibography in patients of 2 group corresponded to 4 degrees of severity, and the secretory capacity of the glands and the quality of secretion corresponded, on average, to 3 degrees and were significantly different from those of patients 1 group and the control groups (0 degree).
Conclusions: Patients with diabetic polyneuropathy have been shown to have more severe ocular surface changes than patients with only Diabetes without diabetic polyneuropathy manifestations.
