Abstract

Background: Dry eye (DE) is a multifactorial disorder that can influence tear production, functional visual acuity and ultimately increase the osmolarity of the tear film. The prevalence of DE ranges from 7% to 33% across the world. However, to the best of our knowledge, the prevalence range of DE in Arab countries is not precisely documented in the literature. Aim: The aim of this article was to determine the prevalence range of DE, investigate the major risk factors of DE and identify the clinical diagnosis and medical management of DE. Method: In this study, only English language articles from 2017 to 2020 were selected. There were 52 articles on prevalence, risk factors, clinical diagnosis and medical management of DE in the Arab population. Results: The prevalence of DE in the Arab population varies in reports, from 10% in the United Arab Emirates (Dubai) to 69% in Palestine (West Bank). Gender difference (DE more in women), wearing of contact lenses, diabetes mellitus and glaucoma were all known to intensify the symptoms of DE. Lastly, there are two approaches to reduce DE in the Arab population, namely, pharmacologic and non-pharmacologic methods. Conclusion: The prevalence of DE in the Arab population was relatively high. In addition, the ocular surface disease index is one of the most common tools for the diagnosis of DE, whilst tear break-up time test is the common clinical test used in the Arab reports. Lastly, the most common treatment for DE is artificial tears.

Highlights

Dry eye (DE) is a multifactorial disorder that can influence tear production, functional visual acuity and increase the osmolarity of the tear film
A less recent report that postulated to determine the prevalence of clinical symptoms associated with risk factors in the King Abdulaziz Specialist Hospital (Taif) was adopted by Alzahrani et al.[20]
The most common clinical test used in the Arab reports is the tear break-up time (TBUT)

Summary

Introduction

Dry eye (DE) is a multifactorial disorder that can influence tear production, functional visual acuity and increase the osmolarity of the tear film. Previous data have shown that the prevalence of DE ranges from 7% to 33% across the world.[6,7] Researchers likewise suggested that the rates of DE vary widely from one population to another because of different definitions, race diversity, types of clinical diagnostic test used, lifestyle, specific regions and age range.[8,9,10,11] the exact percentage of DE is not accurately estimated worldwide.[12] Cases with positive DE signs and clinical symptoms often result in impairment militating against achieving a productive lifestyle, social living and even standard level of education.[13,14]
