Frequency. ~2% of adults [ 5] Amblyopia, also called lazy eye, is a disorder of sight in which the brain fails to fully process input from one eye and over time favors the other eye. [ 1] It results in decreased vision in an eye that typically appears normal in other aspects. [ 1] Amblyopia is the most common cause of decreased vision in a ...
Amblyopia. Anisometropia is a condition in which a person's eyes have substantially differing refractive power. [ 1] Generally, a difference in power of one diopter (1D) is the threshold for diagnosis of the condition. [ 2][ 3] Patients may have up to 3D of anisometropia before the condition becomes clinically significant due to headache, eye ...
Elizabeth Quinlan is an American neuroscientist and a professor at the University of Maryland. [1] There she serves as the Clark Leadership Chair in Neuroscience and as the Director of the Brain and Behavior Institute (BBI).

Specialty. Ophthalmology. Exotropia is a form of strabismus where the eyes are deviated outward. It is the opposite of esotropia and usually involves more severe axis deviation than exophoria. People with exotropia often experience crossed diplopia. Intermittent exotropia is a fairly common condition. "Sensory exotropia" occurs in the presence ...
Visual impairment. Visual or vision impairment ( VI or VIP) is the partial or total inability of visual perception. In the absence of treatment such as corrective eyewear, assistive devices, and medical treatment, visual impairment may cause the individual difficulties with normal daily tasks, including reading and walking.

Stereoblindness (also stereo blindness) is the inability to see in 3D using stereopsis, or stereo vision, resulting in an inability to perceive stereoscopic depth by combining and comparing images from the two eyes . Individuals with only one functioning eye have this condition by definition since the visual input of the second eye does not ...
NEI has supported research into effective treatment for amblyopia, including: Amblyopia treatment in older children: This study aimed to evaluate whether children older than 7 years with amblyopia could benefit from the treatments used in younger children (prescription eyeglasses, patching, and atropine eye drops). The results showed that older ...
Strabismus is a misalignment of the eyes and may also result in amblyopia (lazy eye) or impairments of binocular vision. Medication [ edit ] Pharmacologic injection treatments can be given to cooperative adults under local anesthesia in an outpatient setting, and for some agents, under light general anesthesia.
