Phoria (Heterophoria) Treatment in Mission Viejo, 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.

Mission Viejo families should know that phoria (heterophoria) can affect patients of all ages. Our practice provides age-appropriate evaluation and treatment, with clear explanations that help every family member understand the care plan.
