Families in Kolkata seeking specialist functional vision care have generally had two options: accept a general ophthalmology plan, or travel out of state repeatedly. Neither is a good fit for a treatment that depends on weekly supervision over several months. We deliver COVD/OVDRA-certified binocular vision therapy by secure telehealth, weekly, from home.
An ophthalmological examination establishes that the eye is structurally sound. A functional vision assessment establishes what the brain does with the images the eyes send. Both are necessary; neither substitutes for the other.
This is the source of most of the confusion families arrive with. Being told the eyes are perfectly healthy is accurate and reassuring, and it is entirely compatible with amblyopia. The pathology in amblyopia is not in the eye; it is in how the visual cortex has learned to weight the two inputs.
What a functional assessment adds is a specific set of measurements: acuity for each eye independently, the depth and extent of suppression, fusion range, and stereoacuity. None of those appear on a standard eye-health report, and all of them are what a therapy decision rests on.
A Kolkata child’s day often ends with two or three hours of private tuition after a full school day. That is a heavy sustained near-work load, and it is the demand that separates a visual system running on both eyes from one running on one. Complaints that appear only in the last hour of the evening are worth taking seriously.
Fatigue that is specific to the end of a long near-work session is a functional pattern. Structural eye disease rarely behaves that way.
A weekly live session with fifteen to twenty minutes of daily home practice, scheduled around school and tuition timings.
The first consultation
A full binocular baseline established locally rather than on a journey out of state: suppression depth, fixation stability, alignment and stereoacuity, all recorded so that nothing has to be re-established later.
Refraction and adaptation
The correction confirmed and coordinated with a dispensing optician of your choosing, with an adaptation period allowed before therapy begins rather than compressed into it.
The therapy programme
Anti-suppression and dichoptic work in short daily blocks, scheduled around school and the tuition hours that follow, with one supervised live session a week to re-grade the load.
Follow-up and discharge
Remeasurement at session eight, then a structured taper with reviews at three and six months — continuity that historically meant repeated out-of-state journeys and now does not.
Kolkata and Greater Kolkata
The clinical question in Kolkata is the same as anywhere. What differs is how far families have had to travel to have it answered properly.
Pattern one
One excellent assessment in another city, a plan that requires weekly supervision, and no realistic way to attend it. The plan was right; the delivery model was impossible. Weekly video supervision makes the same plan executable.
Pattern two
Glasses issued, review each year, acuity unchanged each time. Nobody has measured suppression or stereopsis, so nothing has ever prompted a change of approach.
Pattern three
Complaints that appear only after several hours of continuous close work. Frequently attributed to tiredness or lack of interest, and frequently a binocular finding once measured.

We coordinate with your existing ophthalmologist and send them our measurements in writing. This is an adjunct to their care, not an alternative to it.
Not necessarily, and this is the single most common misunderstanding we deal with. Amblyopia occurs in structurally healthy eyes almost by definition — the eye is normal and the brain has learned to under-use it. So a clean eye-health examination and a diagnosis of amblyopia are entirely consistent with each other. What settles the question is a per-eye acuity test plus a suppression and stereo assessment, none of which forms part of a routine eye-health check.
For amblyopia specifically, the overlap is high. The measurements that guide the programme — monocular acuity, suppression, fusion range, stereoacuity — can be taken remotely with calibrated targets, and the therapy itself has always been performed at home between appointments. What travel buys you is a physical examination, which is worth doing once. What it costs is the weekly consistency the treatment actually depends on. For most families the better arrangement is one local physical examination and weekly remote supervision.
Yes, and children who do well academically are among the most frequently missed, because there is no obvious problem to investigate. A bright child compensates: reads more slowly but understands more, so the marks stay adequate while the effort required stays invisible. The signal is usually effort rather than outcome — how long homework takes, how quickly reading stamina runs out, whether the last hour of the evening looks like the first.
It is low-risk. The activities present a different image to each eye at controlled contrast, which is a normal visual demand rather than a stressful one. Mild headache or fatigue in the first week is the usual complaint and settles as the load is titrated. The one safeguard that matters clinically is that any newly reported double vision is mentioned promptly, because it changes what we do next.
Possibly, and the first job is to establish why the patching did not work. There are three usual answers: an inaccurate prescription underneath it, adherence that was lower than reported, or suppression that patching alone was never going to address. Binocular therapy targets the third directly. If one of the first two is the real explanation, that is worth knowing before starting anything new.
