Disease Features convergence insufficiency and excess
Absence or low individual and public risk
Convergence insufficiency and excess - what does this mean
Convergence insufficiency and excess is a condition that affects the ability of the eyes to work together. it is caused by an imbalance between the extraocular muscles that control eye movement, resulting in difficulty focusing on near objects and a tendency for the eyes to drift outward when attempting to look at something close up. excess convergence is the opposite of convergence insufficiency, and is characterized by an over-activity of the extraocular muscles. this can cause the eyes to cross or turn inward when attempting to focus on something at a close distance.
What happens during the disease - convergence insufficiency and excess
Convergence insufficiency and excess is a condition in which the eyes are unable to work together to focus on near objects. it is caused by a disruption in the normal balance between the muscles that control eye convergence and divergence. this disruption can be caused by a variety of factors, including muscle weakness, trauma to the eye muscles, neurological issues, and refractive errors. treatment is typically centered around vision therapy, which helps to strengthen the eye muscles and improve coordination between the eyes.

How does a doctor diagnose
- Conduct a comprehensive eye exam, including tests for refractive error, binocular vision, and ocular alignment.
- Evaluate the patient's nearpoint of convergence (NPC) and nearpoint of accommodation (NPA).
- Perform a cover test to assess for ocular alignment.
- Administer a vergence facility test to measure the patient's ability to maintain and shift vergence.
- Conduct a monocular estimation test to assess the patient's ability to maintain fixation.
- Administer a phoria test to measure the patient's degree of ocular alignment.
- Administer a vergence amplitude test to measure the patient's ability to move his or her eyes in a coordinated fashion.
- Conduct a stereoacuity test to assess the patient's ability to perceive depth.
- Conduct a monocular accommodative facility test to measure the patient's ability to maintain and shift accommodation.
- Administer a positive fusional vergence test to measure the patient's ability to maintain binocular fusion.
Treatment and Medical Assistance
Main Goal: Treating the Symptoms of Convergence Insufficiency and Excess
- Prescribing prism lenses to improve eye alignment
- Prescribing vision therapy to improve eye coordination
- Prescribing eye exercises to improve eye convergence
- Prescribing eye drops to reduce eye strain
- Prescribing special glasses to reduce eye fatigue
- Prescribing medications to reduce inflammation
- Prescribing nutritional supplements to improve eye health
- Prescribing lifestyle changes to reduce stress
- Prescribing vision therapy to improve visual perception
8 Days of Hospitalization Required
Average Time for Outpatient Care Not Established
Convergence insufficiency and excess - Prevention
Convergence insufficiency and excess can be prevented by regularly exercising the eyes. this includes activities such as focusing on a distant object, then a near object, and repeating this several times a day. additionally, it is important to ensure that the eyes are not overused and that adequate rest is taken. good nutrition and avoiding eye strain from prolonged use of digital devices may also help prevent convergence insufficiency and excess.
