Investigation of Dry Eye Symptoms in Lecturers by Ocular Surface Disease Index

Dry Eye Disease in the Middle East and Northern Africa: A Position Paper on the Current State and Unmet Needs

In the Middle East and Northern Africa (MENA), dry eye disease (DED) is often misdiagnosed or overlooked. This review summarizes a series of conversations with ophthalmologists in the region around a variety of climatic, lifestyle, and iatrogenic factors that contribute to specific features of DED in the MENA region. These considerations are further classified by patient lifestyle and surgical choices. All statements are based on discussions and formal voting to achieve consensus over three meetings. Overall, a deeper understanding of the disease characteristics of DED specific to MENA can better guide local eyecare practitioners on appropriate management and follow-up care. Additionally, population-based studies and patient and physician education on ocular surface diseases, together with the use of culturally appropriate and language-specific questionnaires can help ease the public health burden of DED in this region.

Symptomatic Dry Eye Disease and Associated Factors Among Adult Diabetic Patients in Adare General Hospital, Hawassa City, Southern Ethiopia, 2023

Introduction

Symptomatic dry eye disease is a multifactorial ocular surface condition caused by disruption of the precorneal tear film and is a common clinical finding in diabetic patients. However, there was no study on the prevalence and associated factors of symptomatic dry eye disease among diabetic patients in Ethiopia or in the study area.

Purpose

This study aimed to investigate the prevalence and associated factors of symptomatic dry eye disease among adult diabetic patients in Adare General Hospital, Hawassa City, Southern Ethiopia, in 2023.

Methods

A hospital-based cross-sectional study design was conducted on 493 adult diabetic patients who were selected using systematic random sampling, from April 23 to June 8, 2023. Data were collected through a face-to-face interview using an ocular surface disease index questionnaire. Binary logistic regression was performed to identify factors potentially associated with symptomatic dry eye disease. Variable with a P value of <0.05 was considered statistically significant.

Results

A total of 488 subjects participated in this study with a response rate of 99%. The prevalence of symptomatic dry eye disease was 34.8% (95% CI = 30.6-39.1). College and university educational status (AOR = 5.88, 95% CI = 2.25-15.38), government employed (AOR = 2.22, 95% CI = 1.05-4.68), use of visual display unit >5 hours (AOR = 4.41, 95% CI = 1.51-12.87), duration of diabetes ≥11 years (AOR = 3.57, 95% CI = 1.28-9.90), poor glycemic control (AOR = 2.13, 95% CI = 1.21-3.75), allergic conjunctivitis (AOR = 1.99, 95% CI = 1.12-3.54), and debris in the tear film (AOR = 3.63, 95% CI = 1.53-8.61) were positively associated with symptomatic dry eye disease.

Conclusion

The study revealed a high prevalence of symptomatic dry eye disease. Higher educational status, government employed, use of visual display unit, longer duration of diabetes, poor glycemic control, allergic conjunctivitis, and tear film debris were significantly associated with symptomatic dry eye disease. Breaks in screen use, good glycemic control, and treatment of ocular morbidities such as allergic conjunctivitis and debris in the tear film were recommended for all diabetic patients.

High Prevalence of Symptomatic Dry Eye Disease Among University Students During the COVID-19 Pandemic in University of West Indies, Trinidad and Tobago

BACKGROUND

The Covid-19 pandemic lockdown obligated higher education students to attend online courses, leading to prolonged exposure to digital displays. Excessive time on digital devices could be a risk factor for ocular problems, including symptomatic dry eye. There are limited evidences to show the magnitude of symptomatic dry eye disease and its associated factors during COVID-19 pandemic. This study aimed to fill this gap, among university students in Trinidad and Tobago.

METHODS

An institutional-based cross-sectional study was conducted among undergraduate students attending the University of West Indies, Saint Augustine Campus from October 2020 to April 2021. The standardized ocular surface disease index questionnaire, descriptive statics and binary logistic regression were used to assess the prevalence and associated factors of dry eye diseases. Variables with a p-value of less than 0.05 were considered to be statistically significant.

RESULTS

Four hundred (96.3%) participants completed the questionnaire. Among all, 64.8% were female and 50.5% were east Indians. About 48% were using visual display units for average of 10-15 hours/day. The prevalence of symptomatic dry eye disease was 84.3% (95% CI = 80.8-87.5%) with OSDI score ≥13. Lack of education about dry eye 2.69 (95% CI: 1.41-5.13), use of the reading mode of computer 3.92 (95% CI: 1.57-9.80), refractive error 3.20 (95% CI: 1.66-6.20), previous systemic medications 2.80 (95% CI: 1.15-6.81), and average hours of visual display unit use/day (p<0.001) were significantly associated with symptomatic dry eye disease.

CONCLUSION

Symptomatic dry eye disease was a prominent problem among students at the University of West Indies. Average of >4 hours of visual display unit use/day, refractive error, positive history of systemic medication, lack of education about dry eye, and using computers in reading mode were associated factors.

Symptomatic dry eye disease and associated factors among postgraduate students in Ethiopia

Background

Symptomatic dry eye disease is a growing public health challenge especially among those who are visual display unit (VDU) users and other long-time near activity workers. Globally, computer user adults experience a surge in the prevalence of dry eye. Data is insufficient on the prevalence of dry eye disease among postgraduate students in Ethiopia. Therefore, the present was aimed to assess the prevalence of dry eye and its associated factors among postgraduate students at the University of Gondar, Northwest Ethiopia.

Methods

A cross-sectional study was conducted on a total of 423 postgraduate students who were selected based on a simple random sampling technique. Data was collected through online symptom-based ocular surface disease index questionnaire. Binary logistic regression was used to test the association and p-value of <0.05 was considered to determine the significance of the association.

Results

From the total postgraduate students, 404 completed the study with a response rate of 95.5%. The prevalence of symptomatic dry eye disease was 50.5% (95% CI, 45.1%-54.9%). Average continuous visual display unit use for 2-4hours per day[AOR = 2.57 (95% CI, 1.27–5.21)] and for> 4hours per day[AOR = 3.77 (95% CI 1.87–7.59)], duration of visual display unit use for 3–5 years [AOR = 2.24 (95% CI, 1.17–4.31)], 6–8 years [AOR = 2.46 (95% CI,1.31–4.62)] and > 8 years [AOR = 3.25 (95% CI, 1.63–6.48)], average sleeping hour < 7 hours/day within last week [AOR = 2.17 (95% CI, 1.35–3.49)] and current known allergic conjunctivitis [AOR = 5.42 (95% CI, 2.43–12.10)] were significantly associated with symptomatic dry eye disease.

Conclusion and recommendation

In this study, about half of postgraduate students faced symptomatic dry eye disease. Significant association was observed between symptomatic dry eye disease and average continuous hours of visual display unit use, duration of visual display unit use in years, shortage of sleep and current known allergic conjunctivitis. It is advisable for postgraduate students to limit screen exposure hour and establish regular breaking time along their exposure. It is also advisable to have optimum sleep as possible. It is also important to explore dry eye disease on a large sample incorporating clinical tests.

The association between visual display terminal use and dry eye: a review

BACKGROUND

Dry eye disease (DED) is a multifactorial disease of the tear film and ocular surface. It causes ocular symptoms, reduced quality of life and a considerable economic burden on society. Prolonged use of visual display terminals (VDTs) has been suggested as an important risk factor for DED.

PURPOSE

This review aims to study the association between DED and VDT use with an emphasis on the prevalence of DED among VDT users and harmful daily duration of VDT use.

METHODS

A PubMed search was conducted and yielded 57 relevant articles based on a set of inclusion and exclusion criteria. The studies were subclassified according to study design.

RESULTS

The far majority of the studies showed an association between VDT use and DED or DED-related signs and symptoms. The prevalence of definite or probable DED in VDT and office workers ranged from 26% to 70%, with as few as 1-2 hr of VDT exposure per day being associated with DED.

CONCLUSION

VDT use is strongly associated with DED. VDT-associated DED is prevalent, but the exact prevalence needs to be further elucidated using standardized DED diagnosis criteria. Furthermore, a safe lower limit of daily VDT use has yet to be established. More research is needed on the effect of digitalization and digital transformation, which are particularly high during the time of the COVID-19 pandemic.

The relationship of distance learning with ocular surface disorders in students in the COVID-19 pandemic

Purpose

To evaluate ocular surface disorders in students whose daily screen time increased due to distance learning during the COVID-19 pandemic.

Methods

Eighty-eight eyes of 44 cases were included in this cross-sectional study. The distance learning students with complaints of redness, stinging, and increased blinking were evaluated. Biomicroscopic examination findings, spherical equivalent, keratometry values, and average daily average screen time were recorded. Ocular Surface Disease Index (OSDI) survey and non-contact tear film breakup time (BUT) assessment (Topcon CA-800) were performed.

Results

Forty-four cases between 15 and 25 years old were evaluated; 25 were girls (56.8%), 19 were boys (43.2%), and the mean age was 19.2 ± 3.9 years (15–25). The mean daily screen time was 4.9 ± 0.9 h. The mean non-contact BUT was 3.18 ± 2.0 s (1.24–8.80 s), and the spherical equivalent was -1.39 ± 1.79. Punctate epitheliopathy was present in 33 eyes (37.5%) on biomicroscopic examination. The mean OSDI score was 37.12 ± 20.30 (10–75) points. A significant positive correlation was present between daily average screen time, punctate epitheliopathy (r = 0,341; p = 0,001), and OSDI score (r = 0,510; p < 0,001). There was also a significant positive correlation between the OSDI score and punctate epitheliopathy (r = 0.754; p < 0.001). There was no significant correlation between the non-contact BUT and punctate epitheliopathy, OSDI score, or daily screen time (p > 0.05).

Conclusion

Ocular surface disorders in students can be associated with increasing daily screen time due to distance learning.

Quality of life study in ophthalmic practice

The article discusses various methods for studying the quality of life in all kinds of eye diseases. General and special questionnaires used in modern ophthalmological practice are presented. The presence of a sufficiently large amount of data indicating the relationship between the quality of life and objective indicators of the visual system was established. A fairly good comparability of results obtained in the assessment of various quality of life questionnaires in a patient with ophthalmic condition was revealed.
