It is used by ophthalmologists and orthoptists in order to measure the vertical and horizontal deviation and includes both manifest and latent components. [1]
Esotropias measuring more than 15 prism diopters (PD) and exotropias more than 20 PD that have not responded to refractive correction can be considered candidates for surgery. Techniques Disinserting the medial rectus muscle. The goal of strabismus surgery is to correct misalignment of the eyes.
Where appropriate, prismatic correction can be used, either temporarily or permanently, to relieve symptoms of double vision.
