[1] [8] Without treatment, amblyopia typically persists. [1] Treatment in adulthood is usually much less effective. [1] Amblyopia begins by the age of five. [2] In adults, the disorder is estimated to affect 1–5% of the population. [5] While treatment improves vision, it does not typically restore it to normal in the affected eye. [2]
Amblyopia can, however, arise as a result of esotropia occurring in childhood: In order to relieve symptoms of diplopia or double vision, the child's brain will ignore or "suppress" the image from the esotropic eye, which when allowed to continue untreated will lead to the development of amblyopia. Treatment options for esotropia include ...
Oliver Sacks was the first to make the story of Susan Barry, whom he nicknamed "Stereo Sue", known to the general public.. Stereopsis recovery has been reported to have occurred in a few adults as a result of either medical treatments including strabismus surgery and vision therapy, or spontaneously after a stereoscopic 3D cinema experience.
The "relaxing" nature of reading glasses is believed to reduce the near vision stress and allow normal function. The emotional effects of chronic near vision stress are also reduced. The "non-Malingering" name is a refutation that the patient is malingering.
The management of strabismus may include the use of drugs or surgery to correct the strabismus.Agents used include paralytic agents such as botox used on extraocular muscles, [1] topical autonomic nervous system agents to alter the refractive index in the eyes, and agents that act in the central nervous system to correct amblyopia.
The goal of strabismus surgery is to correct misalignment of the eyes. This is achieved by loosening or tightening the extraocular muscles in order to weaken or strengthen them, respectively. [1] There are two main types of extraocular muscles - rectus muscles and oblique muscles - which have specific procedures to achieve the desired results. [4]
Secondary MFS is a frequent outcome of surgical treatment of congenital esotropia. [2] A study of 1981 showed MFS to result in the vast majority of cases if surgical alignment is reached before the age of 24 months and only in a minority of cases if it is reached later. [5] MFS was first described by Marshall Parks. [3]
