EP stands for which deviation?

• A. Esophoria
• B. Exophoria
• C. Esotropia
• D. Exotropia

Answer: (C)

The question tests your ability to identify the type of ocular deviation described by the abbreviation EP. EP denotes a manifest inward deviation, meaning the eye turns inward and remains misaligned even with both eyes open. This is esotropia, a tropia, not a latent deviation. In contrast, a phoria (like esophoria) is a latent inward drift that only appears when fusion is disrupted, and exophoria or exotropia are outward deviations (latent or manifest). So EP points to esotropia, the inward, visible misalignment.
