The muscles of the eye such as ciliary muscles – become stronger after two months of age, allowing infants to focus on particular objects through contraction and relaxation. Their retinal images are also smaller compared to adults due to shorter distances from the retina to the cornea of the infants' eye. [1]
This test allows for the assessment of grating acuity, especially in children who possess severe or multiple visual deficiencies. The "LEA Gratings Test" has also been shown to be successful in vision testing of children with brain damage and is the only test that can reveal their limited capacity for the processing of large numbers of parallel ...
Retinopathy of prematurity (ROP), also called retrolental fibroplasia (RLF) and Terry syndrome, is a disease of the eye affecting prematurely born babies generally having received neonatal intensive care, in which oxygen therapy is used because of the premature development of their lungs. [2]
Leber's congenital amaurosis (LCA) is a collection of inherited, degenerative eye disorders that can reduce the strength of visual clarity or sharpness in infants and can cause childhood blindness. [ 14 ] [ 15 ] These eye disorders are mostly autosomal recessive diseases, and diagnoses of LCA are linked to multiple gene variants, including the ...
An eye examination, commonly known as an eye test, [1] is a series of tests performed to assess vision and ability to focus on and discern objects. [2] It also includes other tests and examinations of the eyes. [2] Eye examinations are primarily performed by an optometrist, ophthalmologist, or an orthoptist.
The newborn's visual acuity is approximately 6/133, developing to 6/6 well after the age of six months in most children, according to a study published in 2009. [36] The measurement of visual acuity in infants, pre-verbal children and special populations (for instance, disabled individuals) is not always possible with a letter chart.

Credé prophylaxis is the practice of washing a newborn's eyes with a 2% silver nitrate solution to protect against neonatal conjunctivitis caused by Neisseria gonorrhoeae, thereby preventing blindness. [1] The Credé procedure was developed by the German physician Carl Siegmund Franz Credé who implemented it in his hospital in Leipzig in 1880 ...
