Ocular surface assessment in maturity-onset diabetes of the young

Abstract

To examine ocular surface changes in patients with maturity-onset diabetes of young (MODY). Fifty patients with MODY who were transferred to Genetic Diagnosis Department of Diskapi Yildirim Beyazit Training and Research Hospital have been included. All patients were subjected to Ocular Surface Illness Index (OSDI) survey, shirmer test, invasive and non-invasive tear break up time (TBUT), cornea fluorescein, and Lissamine green dye tests. Lastly, meibography measurements have been completed using Sirius Scheimpflug camera (Sirius, CSO, Florence, Italy). All 50 patients had a glucokinase (GCK) mutation. MODY diagnosis time was 5.0 ± 5.5 years (range: 0–20 years) on an average. While the average HBa1c levels were 5.5 (range: 4.8–6.5, reference range: 4–6), none of the patients were diagnosed with diabetic retinopathy in fundus examination. There was no significant difference between MODY and control group in terms of OSDI score, Schirmer 1 test, meibomian gland loss, average BUT, TBUT ((p)0.05). Our work is the first one which specifically evaluates ocular surface in MODY patients. Contrary to the common concept that “dry eye is frequently seen in type 1 and type 2 DM,” we did not come across any significant difference between MODY and control group in ocular surface tests. It might be linked to the fact that not enough time had passed for DR or DES symptoms to be detected. Our patients’ average diabetes diagnosis length might be a short time span for clinical symptoms like DR and DES to show up.
