Abstract/Introduction

SIGNIFICANCE 

These data confirm the effectiveness of office-based vergence/accommodative therapy for improving convergence in children with symptomatic convergence insufficiency. They also highlight the importance of using a primary outcome measure that is as objective as possible rather than relying solely on self-reported symptoms for studies of binocular vision in children.

 

PURPOSE 

The purpose of this study was to report changes in clinical signs and symptoms of convergence insufficiency (secondary outcome measures) from a multicenter clinical trial (Convergence Insufficiency Treatment Trial–Attention & Reading Trial [CITT-ART]) evaluating the effectiveness of vergence/accommodative therapy for improving reading and attention in children with symptomatic convergence insufficiency.

 

METHODS 

Three hundred eleven children aged 9 to 14 years with symptomatic convergence insufficiency were randomly assigned to 16 weeks of office-based vergence/accommodative therapy or to placebo therapy. Improvements in (1) near point of convergence (NPC), (2) positive fusional vergence (PFV), and (3) self-reported symptoms (Convergence Insufficiency Symptom Survey [CISS] score) were compared after 16 weeks of treatment.


Conclusion/Results

RESULTS 

Mean NPC improved 10.4 cm in the vergence/accommodative and 6.2 cm in the placebo therapy group (mean difference of −4.2 cm [95% confidence interval {CI}, −5.2 to −3.2 cm; P < .001]); mean PFV increased 23.2 and 8.8Δ in the vergence/accommodative and placebo therapy groups, respectively (mean difference of 14.4Δ [95% CI, 12.1 to 16.8Δ; P < .001]). The mean CISS score improved 11.8 and 10.4 points in the vergence/accommodative and placebo therapy groups, respectively (mean difference of 1.5 points [95% CI, −3.8 to +0.8 points; P = .21]).

 

CONCLUSIONS 

Our results demonstrate that office-based vergence/accommodative therapy is effective for improving the NPC and PFV in children with symptomatic convergence insufficiency. However, given that both treatment groups had a similar reduction in self-reported symptoms, it may not be prudent to use the CISS alone as a measure of successful treatment.


Testimonials


At Amplify with Dr Wernick I was seeking help for seemingly intractable, probably age-related dryness. I've seen other doctors about it, and that has been helpful, but what he explained to me about it and the careful way he answered all my questions gave me so much more of a clear understanding of what is going on (and is not) that I am more able to implement all his and others' recommendations than I was before. And he gave me additional resources for further follow-up. I am most grateful.

Wow! This is a great Eye Care medical facility. I was thoroughly examined by Dr. Pinkhasov for over 2 hours. She made sure to check my eyes for pretty much everything and patiently explained proper care for my eyes. They definitely know how to provide great care and treat their patients right. Now I know why they have such a great reputation and been around for so long.

Dr. Kavner is a gifted diagnostician and orthoptic therapist. He treated me several decades ago for a condition similar to dyslexia. I was having migraines five times per week. I worked with him for about a year and I experienced tremendous improvement (down to 3-4 per year) that has lasted.

Dr. Kavner recommended two types of eye therapy for my daughter. One of them using bio-feedback. In just three sessions she is seeing considerably better. She shouted this morning: Ooh my God! I could not see these letters with my glasses on, and now I can see them without my glasses. If you are willing and able to invest in improving your vision, this is a good place to go to!

I have always found Dr Kavner's work, expertise and wisdom of the highest caliber. As one of the fathers of OT, occupational othomology, his depth and breadth of knowledge about the eyes' health and wellbeing of the patient is exemplary. Cannot say enough good things about him.
