Aim: To determine the prevalence of dry eye (DE) and some related factors in patients with type 2 diabetic nephropathy (T2DN).

Methods: We performed a cross-sectional study on 338 people, who were divided into 2 groups: 169 T2DN patients and 169 patients diagnosed with type 2 diabetic mellitus (T2DM) without renal complications as a control group. The Ocular Surface Disease Index (OSDI) and test fluorescein tear-film break-up time (TBUT) were done in all 338 subjects. Patients with OSDI scores < 13 and TBUT values equal to or under 10 seconds were diagnosed with dry eye.

Results: The prevalence of DE in T2DN patients was significantly higher than T2DM group (55.6% versus 37.3%). The T2DN groups with dry eye had a median duration of DM, the proportion of hypertension, peripheral nerve complications, anemia, proportion of using insulin, and concentration of plasma glucose, HbA1C, urea, creatinine, CRP-hs significantly higher than those of T2DN without dry eye. Advanced age, high HbA1C level, and decreased eGFR were independent factors associated with dry eye in T2DN patients.

Conclusion: Dry eye was a common condition associated with advanced age, high HbA1C levels, and decreased GFR in T2DN patients.

Blink completeness and rate in dry eye disease: An investigator-masked, prospective registry-based, cross-sectional, prognostic study.

Cont Lens Anterior Eye

January 2025

Department of Ophthalmology, Aotearoa New Zealand National Eye Centre, The University of Auckland, Auckland, New Zealand. Electronic address:

Purpose: To investigate the prognostic ability of blink rate and the proportion of incomplete blinking to predict dry eye disease diagnosis, as defined by the TFOS DEWS II criteria.

Methods: A total of 453 community residents (282 females, 171 males; mean ± SD age, 37 ± 19 years) were recruited in an investigator-masked, prospective registry-based, cross-sectional, prognostic study. Dry eye symptomology, tear film quality, and ocular surface characteristics were assessed in a single clinical session, and blink parameters evaluated by an independent masked observer.

Translation and validation of the 8-item contact lens dry eye questionnaire (CLDEQ-8) among Chinese soft contact lens wearers.

Cont Lens Anterior Eye

January 2025

State Key Laboratory of Ophthalmology, Zhongshan Ophthalmic Center, Sun Yat-Sen University, Guangzhou, China. Electronic address:

Purpose: To develop a Chinese version of the 8-item Contact Lens Dry Eye Questionnaire (CLDEQ-8) with cross-cultural adaption and clinical validation among soft contact lens wearers (SCL) in China.

Methods: The translation and adaptation of the Chinese CLDEQ-8 (C-CLDEQ-8) followed a rigorous methodological process based on cross-cultural research guidelines consisting of three main phases: 1) forward and backward translation of original CLDEQ-8 into Chinese, 2) cross-cultural adaptation performed by medical advising committee, and 3) clinical validation and repeatability test of the translated questionnaire on Chinese SCL wearers. Rasch analysis was also performed to investigate the psychometric properties of C-CLDEQ-8.

Recent years brought considerable attention to the connection between chronic stress and the development of autoimmune diseases. However, little is still known about the impact of prolonged stress reactions on the onset and course of primary Sjögren Syndrome (pSS). This study aimed to seek for associations between chronic stress, resulting from stressful life events, and pSS.

: Diabetes is a well-recognised factor inducing a plethora of corneal alterations ranging from dry eye to reduced corneal sensibility, epithelial defects, and reduced cicatrisation. This cohort study aimed to assess the efficacy of a novel ophthalmic solution combining cross-linked hyaluronic acid (CHA), chondroitin sulfate (CS), and inositol (INS) in managing diabetes-induced corneal alterations. Specifically, it evaluated the solution's impact on the tear breakup time (TBUT), the ocular surface disease index (OSDI), and corneal sensitivity after three months of treatment.

Dry eye disease (DED) is a multifactorial, chronic, and often relapsing condition with a significant impact on patient quality of life (QoL). Symptoms such as ocular discomfort and visual disturbances are diverse and frequently misaligned with objective clinical signs, complicating diagnosis and management. DED not only interferes with daily activities like reading, driving, and computer use but also imposes a substantial economic burden due to direct healthcare costs and reduced work productivity.
