Frequently Asked Questions
Answers on behavioral amblyopia, binocular competition, the crowding phenomenon, why patching alone is insufficient, and how the OculoNeuro Synex platform works.
What is behavioral amblyopia?
Behavioral amblyopia is a neurological definition of amblyopia — a neurodevelopmental condition affecting binocular vision. It is fundamentally a disorder of abnormal binocular interaction where the dominant eye actively suppresses input from the fellow eye through cortical suppression.
Why is amblyopia called a binocular disorder with monocular symptoms?
The reduced vision in one eye is often only a symptom. The primary deficit lies in abnormal binocular interaction — meaning deficits exist in the fellow eye and the overall binocular system too, including eye movement deficits, accommodative deficits, contrast sensitivity loss, and the crowding phenomenon.
What visual deficits are associated with amblyopia beyond visual acuity?
Patients show deficits in eye movement (unsteady fixation, eccentric fixation, saccadic latency), accommodation (reduced accuracy, flexibility), spatial perception (reduced contrast sensitivity, crowding phenomenon), and information processing speed.
What is the crowding phenomenon in amblyopia?
Crowding is difficulty identifying a visual target when surrounded by other stimuli. Amblyopia patients perform significantly worse when letters or objects are closely spaced than when viewed in isolation, affecting reading, object recognition, and visual search.
Why is patching alone insufficient for amblyopia?
Patching is a monocular strategy that does not address the binocular imbalance. Research by Woods, Awan & Gottlieb (BJO, 2006) noted disappointing modest improvements. McGill Vision Research found patching may reinforce binocular imbalance. Binocular dichoptic therapy targeting cortical suppression provides superior outcomes.
What is OculoNeuro Synex?
OculoNeuro Synex is a clinical-grade vision therapy platform featuring 10 scientific games using red-green dichoptic contrast filters to target cortical suppression, plus doctor assessment records, automated review schedule reminders, and longitudinal follow-up tracking.
What games are available?
Search Quest, Smooth Movement, Rapid Movement, Rock Chart, The Shooter, Sky Jumper, Match Gabor, Alpha Blitz, Snake Food, and Letter Bounce. All use red-blue filters to balance ocular dominance.
How does the doctor assessment feature work?
Doctors fill complete clinical sheets with Objective and Subjective Refraction (SPH/CYL/Axis), UCVA/BCVA, prism diopter deviations, and anterior segment findings for each patient.
Is OculoNeuro Synex available in India?
Yes. OculoNeuro Synex supports INR pricing and is designed for eye care clinics across India. Doctor accounts require admin approval with verified medical license numbers.
