Binocular vision in amblyopia: structure, suppression and plasticity

Binocular vision in amblyopia: structure, suppression and plasticity


"....The amblyopic visual system was once considered to be structurally monocular. However, it now evident that the capacity for binocular vision is present in many observers with amblyopia. This has led to new techniques for quantifying suppression that have provided insights into the relationship between suppression and the monocular and binocular visual deficits experienced by amblyopes. Furthermore, new treatments are emerging that directly target suppressive interactions within the visual cortex and, on the basis of initial data, appear to improve both binocular and monocular visual function, even in adults with amblyopia. The aim of this review is to provide an overview of recent studies that have investigated the structure, measurement and treatment of binocular vision in observers with strabismic, anisometropic and mixed amblyopia....."

Comments: Amblyopia (aka lazy eye) has always been a binocular vision/brain problem AND can only be treated appropriately using binocular vision therapy. Amblyopia's reduction in vision is the outward sign of the problem. Using principles of neuroplasticity, you can change the brain so that the patient not only sees better, but also has better depth perception (3D vision) which is important to maintain the better visual acuity AND ones quality of life!!

Evaluation of Visual Function and Retinal Structure in Adult Amblyopes.

Evaluation of Visual Function and Retinal Structure in Adult Amblyopes.


"....Multifocal VEP amplitudes and latencies were significantly affected in amblyopic eyes and, to a lesser extent, in nonamblyopic eyes. Multifocal VEP response latencies were more delayed in anisometropic eyes than in strabismic eyes, suggesting that anisometropic and strabismic amblyopia may represent different neural abnormalities......"

Effect of Rectus Muscle Recession, Resection, and Plication on Anterior Segment Circulation

Effect of Rectus Muscle Recession, Resection, and Plication on Anterior Segment Circulation


"....Postoperative iris filling defects were present in 67% patients after tenotomy and 12.5% patients after plication...."

Comments: Another reason why strabismus surgery may not be the first thing you recommend for those with eye turns!

Effect of Bifocal and Prismatic Bifocal Spectacles on Myopia Progression in Children Three-Year Results of a Randomized Clinical Trial

Effect of Bifocal and Prismatic Bifocal Spectacles on Myopia Progression in ChildrenThree-Year Results of a Randomized Clinical Trial


"...Bifocal spectacles can slow myopia progression in children with an annual progression rate of at least 0.50 D after 3 years. These results suggest that prismatic bifocals are more effective for myopic children with low lags of accommodation...."

Comments: Once again functional/behavioral/developmental optometry  has been proven correct! Research has supported the concept that the environment affects vision development...and this lends additional support to the role bifocals play in myopia control.  Read the full abstract here: http://archopht.jamanetwork.com/article.aspx?articleid=1813321

Just because it is "Natural" it doesn't necessarily mean it is safe!!!

Be wise with complementary medicines: interactions and side effects can happen

"....It is important to understand that certain complementary medicines may interact with prescription medicines. For example, St John's wort is often used to alleviate depression, but can interact with several commonly used prescription medicines by making them less effective or by increasing their side effects. These prescription medicines include antidepressants, the oral contraceptive pill, digoxin, blood-thinning medicines, some cholesterol-lowering medicines,epilepsy medicines, HIV medicines, pain medicines, chemotherapy medicines and medicines used to prevent rejection after an organ transplant.....It's also really important to include your complementary medicines on your Medicines List so you have a record at hand. ...."

Astigmatism and Early Academic Readiness in Preschool Children

Astigmatism and Early Academic Readiness in Preschool Children




"...The presence of astigmatism detected in a screening setting was associated with a pattern of reduced academic readiness in multiple developmental and educational domains among at-risk preschool-aged children. This study may help to establish the role of early vision screenings, comprehensive vision examinations, and the need for refractive correction to improve academic success in preschool children...."

Comments: All of these children deserved a full, comprehensive eye and vision examination. Even though this research methodology included a vision screening, it has been shown time and again via research that vision screening outcomes ARE NOT (and probably never will be) appropriate. Stop the madness. Yes, vision can have detrimental effects on learning. Yes, full eye examinations will result in positive outcomes. It is time for all (medicine and their cohorts) to stop fighting optometry on this and to join optometry to improve the lives of our children. PS some OMDs are starting to realize this.
