Course Description:

This course covers types, incidence, causes and treatments for a 1D or more difference in spherical-equivalent refractive error between the eyes.

Course Objectives:

      1. Identify how common anisometropia is, and who gets it over the lifespan.

      2. Name seven risk factors for developing anisometropia.

      3. Know strategies to prevent and remediate anisometropia.

      4. How does new anisometropia manifest in monovision contact lens fitting of hyperopes?

      5. How does it manifest in monovision myopes?

      6. How does aniso- appear in esotropes?

      7. How does it appear in exotropes?

I. Definitions

      1. Clinically-significant anisometropia (sign)

      2. Clinically-significant aniseikonia (symptom)

      3. Prevalence of each condition

      4. Types of anisometropia (hyperopic, myopic)

      5. Types of aniseikonia (optical, physiologic, neurologic)

      6. Incidence of anisometropia/aniseikonia throughout the lifespan


        Early childhood
