Phoria (Heterophoria) Treatment in Corona del Mar, California

Medically reviewed by Dr. Alexander Bonakdar, O.D. · Updated February 2026

Heterophoria, commonly called phoria, is a latent eye misalignment that becomes apparent only when binocular fusion is disrupted. Unlike strabismus (tropia), where the misalignment is always visible, phorias are controlled by the brain's fusion mechanism. When this compensation breaks down (decompensated heterophoria), patients experience eye strain, headaches, double vision, and difficulty with reading and concentration.

Corona del Mar's coastal environment can influence how phoria (heterophoria) presents and responds to treatment. Factors like UV exposure, wind, and marine air quality are considered in our evaluation and management approach.
