Burt Kushner is an American pediatric ophthalmologist specializing in the diagnosis and treatment of strabismus.Kushner's contributions include demonstration of improved visual fields of patients following strabismus surgery, elucidation of torsional contribution to patients with diplopia, corticosteroid treatment of periocular capillary hemangioma, and novel hypotheses on the mechanism of ...
In recent years, however, successful improvements in persons with amblyopia, convergence insufficiency or other stereo vision anomalies have become prime examples of neuroplasticity; binocular vision improvements and stereopsis recovery are now active areas of scientific and clinical research.

Chronic venous insufficiency (CVI) is a medical condition in which blood pools in the veins, straining the walls of the vein. [1] The most common cause of CVI is superficial venous reflux which is a treatable condition. [ 2 ]
In order to define the rates and orders of R-convergence, one uses the rate and order of Q-convergence of am error-bounding sequence () chosen such that no other error-bounding sequence (′) could have been chosen that would converge with a faster rate and order; any (′) provides a lower bound on the rate and order of R-convergence and the ...
Convergence is a binocular oculomotor cue for distance and depth perception. Because of stereopsis, the two eyeballs focus on the same object; in doing so they converge. The convergence will stretch the extraocular muscles – the receptors for this are muscle spindles. As happens with the monocular accommodation cue, kinesthetic sensations ...

A computer-simulated realization of a Wiener or Brownian motion process on the surface of a sphere. The Wiener process is widely considered the most studied and central stochastic process in probability theory. [1] [2] [3]
Acute onset anisocoria should be considered a medical emergency. These cases may be due to brain mass lesions which cause oculomotor nerve palsy. Anisocoria in the presence of confusion, decreased mental status, severe headache, or other neurological symptoms can forewarn a neurosurgical emergency.
