H51.12
Convergence excess
Clinical Classification Guidelines
Medical Intelligence & Overview
Convergence excess is a condition where the eyes tend to converge, or turn inward, more than necessary when focusing on near objects. This imbalance can lead to eye strain, discomfort, and double vision, especially during close visual tasks. It primarily affects individuals who spend significant time reading, using computers, or engaging in other activities requiring sustained near focus.
Causes & Symptoms
Clinical Causes: Muscle imbalance between the eye muscles responsible for convergence and divergence Refractive errors, especially hyperopia (farsightedness) Amblyopia or lazy eye Uncorrected vision problems leading to over-convergence Genetic predisposition affecting eye muscle coordination Neurological factors affecting eye control
Key Symptoms: Eyestrain or discomfort during reading or close work Double vision when focusing on near objects Blurred vision at close range Headaches after sustained near visual activity Difficulty sustaining focus when reading or working on a computer Crossed or misaligned eyes noticeable at near distances
Diagnostic & Treatment
Diagnosis Path: Diagnosis of convergence excess involves a comprehensive eye examination by an eye care professional. The professional will perform specific tests to assess eye alignment and convergence ability, including cover tests and near point of convergence testing. Additional assessments may be conducted to rule out other binocular vision issues or refractive errors.
Treatment Protocols: Treatment options aim to improve eye coordination and reduce symptoms. These may include:
