Binocular vision: Part 2 - Compensation and decompensation in heterophoria.

The article discusses binocular vision assessment, which includes assessing the level of heterophoria, stereopsis, and measures to be taken on decompensation of heterophoria. It reports the relationship of the vergence mechanism with misalignments. It also emphasizes refractive errors, fixation disparity, fusional reserves, and cover test recovery. Management includes eye exercise, spherical manipulation of the refractive correction, and prism prescription.
