Abstract/Introduction

Purpose

In a prospective observational study, we previously reported that weaning (tapering or gradually reducing) treatment in children treated with 6 to 8 hours of daily patching for amblyopia resulted in a 4-fold reduction in odds of recurrence. We now report the association of additional factors with recurrence or regression of amblyopia in 30 this same cohort.

 

Design

Prospective, nonrandomized, observational study.

 

Participants

69 children aged less than 8 years, with successfully treated anisometropic or strabismic amblyopia (improved at least 3 logarithm of the minimum angle of resolution (logMAR) lines).

 

Methods

Patients were enrolled at the time they stopped patching for amblyopia. Patients were classified according to whether patching was stopped abruptly or weaned prior to cessation. They were followed off treatment for 52 weeks to assess recurrence of amblyopia.

 

Main outcome measure

Recurrence of amblyopia defined as a 2 or more logMAR level reduction of visual acuity from enrollment (cessation of patching), confirmed by a second examination. Recurrence was also considered to have occurred if treatment was restarted with a 2 or more logMAR level reduction of visual acuity even if it was not confirmed by a second examination.


Conclusion/Results

Results

The risk of recurrence was higher with better visual acuity at the time of cessation of treatment (adjusted risk ratio (RR)=0.68 per line of worse visual acuity (VA), 95% confidence interval (CI)=0.51, 0.90), a greater number of lines improved during the previous treatment (adjusted RR=1.5 per line increase, 95% CI=1.1, 2.0), and a prior history of recurrence (adjusted RR=2.7, 95% CI=1.5, 4.9). Orthotropia or excellent stereoacuity at the time of patching cessation did not appear to have a protective effect on the risk of recurrence.

 

Conclusions

The higher risk of recurrence in the most successfully treated children with amblyopia and absence of protection from orthotropia and excellent randot dot stereoacuity suggests that careful and prolonged follow-up is needed for all children who have been previously treated for amblyopia.


Testimonials


  • Such a nice optician. My grandson is only 4 and needs glasses. We were so sad, but he explained the issues, and we will follow up as he suggested.


    Anna P.

  • I had such a good experience with the clinic. Very friendly staff and doctor, did not have to wait for long to be called, and was treated respectfully. Thanks, American Family.


    June S.

  • Dr. Zurcher has gone above and beyond what any other eye doctor has ever done to figure out what is going on with my eyes. Very happy with American Family Vision.


    Christine R.

  • Family Vision Clinic changed our lives! My daughter was frequently car sick, and she was getting headaches every day, often painful enough that they brought her to tears. We saw a string of doctors and therapists, but we made no progress. Finally, we found Dr. Levi Zurcher and his eye therapist Rain. After ten weeks of eye therapy my daughter no longer gets headaches, and she no longer gets car sick. Daily tears are a thing of the past. I really can’t say enough about this clinic. It was fascinating to watch Dr. Zurcher work. For the first time, someone who knew what they were doing was intently studying my daughter, really trying to figure out all of her eye issues, and his therapist Rain is one of the most patient and lovely people that I’ve ever had the good fortune to meet. We’re finished with eye therapy—yay!—and I have switched to American Family Vision Clinic for all of my family’s other eye health needs.

  • Very professional, yet kind and helpful. They do what they can to make the appointment comfortable. I was running a bit late, I made sure ti call. They were able to switch me with a patient who was already there, they treated me with respect, and helped my son have confidence by getting him the eye care he needed that day. Thank you so much! Would recommend to anyone. It's a blessing that they care enough to work with people who have all different types of insurance from work to state coverage.
