Convergence insufficiency (CI) | Vision Therapy In Kolkata

Convergence Insufficiency (CI) is a common vision disorder where the eyes have difficulty working together to focus on near objects. This can cause eye strain, blurred vision, and difficulties with reading, learning, and daily activities.

Symptoms

Eye strain: Fatigue, discomfort, or pain in the eyes, especially when reading or performing near tasks.
Blurred vision: Difficulty seeing clearly, especially when focusing on near objects.
Double vision: Seeing two images of a single object, especially when reading or performing near tasks.
Headaches: Frequent or recurring headaches, especially after reading or performing near tasks.
Difficulty with reading: Trouble reading, including difficulty with comprehension, fluency, or focus.
Difficulty with learning: Trouble learning new information, especially in academic settings.
Avoidance of near tasks: Avoiding activities that require near vision, such as reading, writing, or using digital devices.

Causes

Genetics: Family history of convergence insufficiency or other vision disorders.
Brain injury: Traumatic brain injury or concussion can cause CI.
Neurological conditions: Conditions like ADHD, autism, or multiple sclerosis can increase the risk of CI.
Prolonged near work: Extended periods of near work, such as reading or using digital devices, can contribute to CI.

Diagnosis

Comprehensive eye exam: A thorough eye exam to assess visual acuity, refraction, and eye alignment.
Convergence testing: Specialized tests to evaluate the eyes’ ability to converge and focus on near objects.
Near point of convergence testing: Measures the closest point at which the eyes can converge and focus.
