An eye that deviates inward when covered and returns to midline when uncovered is called:

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

Answer: (A)

This item tests recognizing a latent eye misalignment (a phoria) revealed by the cover test and identifying the direction of that latent deviation. When the fixing eye is covered, the other eye drifts inward toward the nose, showing an inward drift that is not present with both eyes open because fusion keeps alignment. Once the cover is removed, fusion realigns the eyes back to midline, so there is no persistent misalignment. An inward drift that appears only during cover testing is called an esophoria. In contrast, a tropia is a constant misalignment visible even with both eyes open, such as esotropia (constant inward deviation) or exotropia (constant outward deviation). Similarly, an outward drift observed on cover testing would indicate an exophoria.
