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 ...
A dog with degenerative myelopathy often stands with its legs close together and may not correct an unusual foot position due to a lack of conscious proprioception. Canine degenerative myelopathy, also known as chronic degenerative radiculomyelopathy, is an incurable, progressive disease of the canine spinal cord that is similar in many ways to amyotrophic lateral sclerosis (ALS).
However, a constant unilateral strabismus causing constant suppression is a risk for amblyopia in children. Small-angle and intermittent strabismus are more likely to cause disruptive visual symptoms. In addition to headaches and eye strain, symptoms may include an inability to read comfortably, fatigue when reading, and unstable or "jittery ...
Sudden acquired retinal degeneration syndrome. Sudden acquired retinal degeneration syndrome ( SARDS) is a disease in dogs causing sudden blindness. It can occur in any breed, but female dogs may be predisposed. [1] Approximately 4000 cases are seen in the United States annually. [2]
When refractive errors in children are not treated, the child may be at risk of developing ambylopia, where vision may remain permanently blurry. [19] Because young children typically do not complain of blurry vision, the American Academy of Pediatrics recommends that children have yearly vision screening starting at three years old so that unknown refractive errors or other ophthalmic ...
August is Amblyopia Awareness Month, a good time to learn more about an eye condition commonly known as lazy eye and what can be done to treat it.
Progressive retinal atrophy (PRA) is a group of genetic diseases seen in certain breeds of dogs and, more rarely, cats. Similar to retinitis pigmentosa in humans, [ 1] it is characterized by the bilateral degeneration of the retina, causing progressive vision loss culminating in blindness. The condition in nearly all breeds is inherited as an ...
Sometimes, they behave in surprising ways, and nothing can prepare us for the experience until it happens. One set of pet parents recently found themselves in one of these situations. While they ...
