Surgical correction; Surgical correction of the hypertropia is desired to achieve binocularity, manage diplopia and/or correct the cosmetic defect. Steps to achieve the same depend on mechanism of the hypertropia and identification of the offending muscles causing the misalignment.
The prism cover test (PCT) is an objective measurement and the gold standard in measuring strabismus, i.e. ocular misalignment, or a deviation of the eye. It is used by ophthalmologists and orthoptists in order to measure the vertical and horizontal deviation and includes both manifest and latent components. [1]
Prism correction is measured in prism dioptres. A prescription that specifies prism correction will also specify the "base". The base is the thickest part of the lens and is opposite from the apex. Light will be bent towards the base and the image will be shifted towards the apex.
Maddox rod. The Maddox rod test can be used to subjectively detect and measure a latent, manifest, horizontal or vertical strabismus for near and distance. The test is based on the principle of diplopic projection. [1]

A video covering the Bagolini Striated Test The BSGT is used for patients with strabismus to test for suppression , normal retinal correspondence or abnormal retinal correspondence , [2] particularly in cases of manifest strabismus.
The exchange, captured on video obtained by The Associated Press, took place during an investigation into the death of Charles Givens, a developmentally disabled inmate at the Marion...
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]
