7. For patients with moderate amblyopia (20/80 acuity or better), two hours of daily patching is recommended, based on data from the ATS.12,13, Research suggested that a weekend atropine regimen was as effective as daily atropine for amblyopia treatment, and that Bangerter filters can be used as an alternative to patching as a treatment for patients with amblyopia.14,15. Treatment of bilateral refractive amblyopia in children three to less than 10 years of age. It found that patients in the office-based vision therapy group had lower scores on the Convergence Insufficiency Symptom Survey (CISS), a survey used to quantify symptoms in children with CI, as well as near-point of conversion (NPC) and positive fusional vergence (PFV) values that had improved significantly more than the other treatment groups. The patient wears a red filter over the sound eye with no filter over the amblyopic eye and completes activities using a red pen or pencil that can be seen by the amblyopic eye only. Am J Ophthalmol. A study, looking at 50 children on Individual Education Plans (IEPs) compared with age-matched controls and did full binocular work ups. 2013;120(11):2270-7. A child with reading trouble who persists in trying to read and but gets headaches is symptomatic. If prescribing atropine, be sure to educate the patients on pupillary dilation and blur. • Concussion – a recent study found that 49% of children and adolescents had CI after a concussion.1, • ADHD – a retrospective review found that 9.8% of children with CI had a diagnosis of ADHD; and 15.9% with a diagnosis of ADHD had a diagnosis of CI.2, • Lyme disease – a retrospective review of pediatric and adult patients with Lyme disesae found that 53% had CI.3, • Stimulant medications (methylphenidate, dexmethylphendate, dextroamphetamine) – package inserts report “Difficulites with accommodation” or “blurring of vision.”. 3. Reading problems can be broken into two main classifications: visual efficiency problems and visual processing or perceptual problems.

Commercially available matching games, playing cards and other activities that patients with amblyopia can use to incorporate binocular therapy into their treatment plan. 22. A randomized trial of increasing patching for amblyopia. Convergence is the inward turning of the eyes toward the nose to focus on a near object. Binocular Vision and Ocular Motility has become a major source of references to the older strabis-mus literature that is not retrievable through elec-tronic search techniques. Soldiers can see around corners without risk of exposure Children do not like to wear a patch and may try to remove it, frustrating parents. All rights reserved. Patients on certain medications—particularly for attention problems and depression—may have accommodative problems, patients who have had a traumatic brain injury (TBI) or concussion may also have binocular problems (See ‘Five Additional Causes for Binocular and Accommodative Problems’). A randomized trial comparing Bangerter filters and patching for the treatment of moderate amblyopia in children. 10. Solutions that solve our customers' toughest challenges. 2003;110(11):2075-87. Treatment of anisometropic amblyopia in children with refractive correction. We know more about treating these conditions today than we did 20 years ago thanks, in part, to an increase in binocular vision research. 2018;186:104-15. The relationship between convergence insufficiency and ADHD. Glen Burnie, Maryland 21062 For more information, please call: 410-768-7000 (to speak with a customer agent). Basic techniques such as stereopsis, cover test and near point of convergence can provide significant information regarding a patient’s binocular status. Field of vision. One of the most common conditions that can affect a patient’s near binocular status is convergence insufficiency (CI). The phrase “reading problems” itself can mean different things to different people. 19. These include poor comprehension, letter and word or number reversals, difficulty remembering what was read, struggling to recognize words and problems sounding out words. Wallace D, Lazar E, Holmes J, et al. One such company, Vivid Vision, employs the use of virtual reality goggles with their platform to treat amblyopia, strabismus and vergence disorders. Dr. Bodack is an associate professor and chief of the Pediatric Primary Care Service at Southern College of Optometry. Although, to date, no large-scale randomized clinical trials of vision therapy for CI in adults are available, smaller scale studies show some success.5-8 One such study on adult males found that 62% of patients who received in-office plus home therapy and 30% of patients who received only home therapy were successfully treated with vision therapy.8 Many of the therapy techniques used in this study were the same used by the CITT group. Prior to the ATS studies, research had no information on potential treatment for children older than seven with amblyopia. 15. One of the major criticisms of amblyopia treatment is that treating children and teenagers with patching can be difficult for both patient and parent. Similarly, in patients with strabismic and combined mechanism amblyopia, 75% improved two or more lines of visual acuity with spectacle correction alone, with resolution of amblyopia occurring in more than a third of patients.11 Treating patients with spectacles first can help improve visual acuity, which can make penalization therapy easier for a patient. A randomized trial of patching regimens for treatment of moderate amblyopia in children. A randomized trial of prescribed patching regimens for treatment of severe amblyopia in children. Their protocol involves having the patient wear virtual reality goggles and play interactive games that have the patient stop oncoming targets with their hands, pop targets with their fingers or aim their eyes to look at a target.

Soldiers get real-time, actionable intelligence through the fusion of Image Intensified (I2) white phosphor tubes and thermal imaging. Am J Ophthalmol. 11. The practitioner should reevaluate the patient after eight or 10 sessions. Ophthalmol. Holmes J, Manny R, Lazar E, et al. Similarly, when examining a child with amblyopia, particularly if it is anisometropic and the parent had no concerns prior to the child’s failing a school screening, it is important to realize that child may not complain that one eye does not see. If visual acuity is reduced at distance or near, this reduced acuity may adversely impact the patient’s ability to read. Ophthalmol. The CITT was a randomized clinical trial looking at vision therapy as a treatment for CI in children ages nine to 18 years.2 Twelve weeks of office-based vision therapy were compared with office-based placebo therapy as well as home-based pencil push-up therapy and home-based computer therapy plus pencil push-ups. The ENVG-B is a helmet-mounted, dual-waveband goggle with industry-leading, fused white phosphor and thermal technologies. Master CL, Scheiman M, Gallaway M, Goodman A, et al. In a study of five to seven year olds using this treatment for 16 weeks, researchers found that the amblyopic eye acuity improved with patching and video game play; however, the improvement was not as good in the video game group as in the patching group.17 Surprisingly, compliance was actually better in the patching group.17 In an older cohort aged 13 to 16 years, amblyopic patients had a minimal response to the therapy.17,18, Other technologies have employed the use of dichoptic movies instead of video games for amblyopia. The vision therapy protocol in the CITT study focused on accommodation, voluntary convergence and fusional vergence.2 Although many techniques can be accomplished with traditional methods, more sophisticated and equipment intensive therapy techniques such as vectograms, aperture rule and computerized orthoptics were also included in CITT.2, When conducting vision therapy, assess the patient’s signs and symptoms at regular intervals.2 Although the CITT used 12 weeks of 60-minute therapy sessions for the study, in practice, sessions may be closer to 30 or 45 minutes.2, In the same way that research has improved our understanding of CI, the PEDIG ATS studies have helped optometry deepen its understanding of amblyopia treatment.9,10 From these studies, we know that when seeing a patient with amblyopia, the recommended treatment is to prescribe glasses and then monitor the patient’s visual acuity every six to eight weeks.9,10 That research shows that, in patients with isoametropic amblyopia, 73% obtained 20/25 visual acuity (VA) in one year with glasses alone.9, In patients with anisometropic amblyopia, approximately one-third showed resolution of the amblyopia with refractive correction alone and more than 75% of patients improved two lines or more in visual acuity.10.
