Age related strabismus

Age related binocular vision disorders (age related strabismus) could include all types of spontaneous strabismus appearing along the lifetime, which are directly connected with the aging process. Neurological strabismus is excluded. Functional and structural changes related to the aging process can induce phoria decompensation, convergence insufficiency decompensation and new onset strabismus as distance esotropia or vertical strabismus induced by the sagging eye syndrome. MRI studies sustain the hypothesis of age related structural changes of extraocular muscles pulleys and their influence on the eye position and motility nominated as sagging eye. Age Related Distance Esotropia, Age Related Divergence Insufficiency Esotropia are probably different names for the same type of strabismus. All types of age related binocular disorders require treatment because of the accompanying diplopia. Prisms or/ and surgery can improve the patients' life quality by eliminating diplopia in primary position and main gazes.
