Background:
Hearing loss is a common disability affecting 5% of the world's population. A lack of opportune diagnosis affects both the individual and society. In order to develop public health policies in the field of hearing health, countries must have information about epidemiology.
Aims/Objectives:
In this review, we describe the information available about prevalence and incidence of hearing loss in school-aged children.
Material And Methods:
Review of the literature in PubMed.
Results:
Reported prevalence of hearing loss in school-aged children varied between 0.2% and 7.8%. Several factors could explain the discrepancy in numbers such as definition of hearing loss, cause, and the inclusion of high-frequency hearing loss. The rate of delayed-onset hearing loss at the age of six years old varied between 0.6 and 0.8 per 1000.
Conclusions And Significance:
The prevalence of hearing loss in school-aged children varied between 0.2% and 7.8%, and the rate of delayed-onset hearing loss at the age of six years old varied between 0.6 and 0.8 per 1000.

Photoreceptors
The retina is composed of several layers and contains specialized cells called photoreceptors. The photoreceptors (rods and cones) change their membrane potential when stimulated by light energy. There are two types of photoreceptors—rods and cones—which differ in the shape of...
