Pattern one
The precision-work adult
Judging clearances by eye, compensating well until fatigue sets in and error rates climb. Stereoacuity has never been measured and the person is surprised there is a number for it.
For a child, the target of an amblyopia programme is acuity and binocularity. For a working adult it is usually neither — it is depth judgement, fusion range and how long a demanding visual task can be sustained. Those are different endpoints, measured differently and treated differently. We are explicit about which one applies to you. Across Pune and Pimpri-Chinchwad by telehealth.
Pune and Pimpri-Chinchwad
Technology campuses to the west, an engineering and automotive belt to the north, and a large student population produce three quite distinct groups with three different endpoints.
Pattern one
Judging clearances by eye, compensating well until fatigue sets in and error rates climb. Stereoacuity has never been measured and the person is surprised there is a number for it.
Pattern two
Fine for an hour, finished after two, in full-time study or professional exams. Acuity in the dominant eye is normal, which is why every eye test has cleared them.
Pattern three
A large difference between the eyes picked up at a routine prescription check, glasses issued, review in a year. Glasses are essential and rarely sufficient on their own.

Running an adult through a paediatric protocol and judging it by a paediatric endpoint is a reliable way to produce a disappointing result from a treatment that was working.
In a child, the visual system is still organising and chart acuity in the weaker eye can shift substantially, so acuity is a fair primary endpoint. In an adult, acuity is largely settled and chasing it produces small numbers and a discouraged patient — while fusion range, stereoacuity and sustainable near-work duration often improve considerably.
The practical consequence is which measurements we track and what we call success. An adult who gains two lines of acuity and no stereo function has arguably gained little of daily value. One whose acuity is unchanged but who acquires measurable stereopsis and can work a full day without one-sided fatigue has gained a great deal.
Almost every adult who arrives with a childhood amblyopia history has had their acuity measured many times and their stereoacuity measured never. It takes minutes, it is the function that tracks the practical difficulties they describe, and it is the strongest single predictor of how well binocular therapy will work for them.
One live session a week and short daily practice, scheduled around campus and shift timings across Pune and PCMC.
Finding the starting point
A baseline constructed to be repeatable: identical targets, distances and sequence at every measurement, since in a largely self-managed programme measurement drift is the main threat to interpreting progress.
Sorting the prescription
The prescription settled first, with the adaptation interval timed to fall in a lighter teaching week rather than across an assessment period.
Building the function
Progressive dichoptic load with difficulty adjustable by the patient between sessions, and a written practice log, which is what makes a self-directed programme auditable at review.
Checking the gain
Assessment against the original figures at session eight, then a taper rather than an abrupt end, because programmes stopped cleanly at the close of a term are the ones that regress over the break.
If several of these are familiar, a stereoacuity measurement will establish in minutes whether they share a single cause.
It depends almost entirely on your baseline stereoacuity, which is why we measure it before promising anything. With measurable residual stereo function, expanding fusion range typically produces a clear reduction in screen fatigue and easier depth judgement over a programme of several months. With none at all, gains are smaller and slower. We give you that assessment at the baseline, in specific terms, rather than after you have spent the six months — and if the expected return is poor we will say so.
We will not design a programme around passing an assessment, and we do not issue certificates for that purpose. What we can do is measure the functions those checks typically examine — monocular acuity, fusion, stereoacuity — tell you where you currently stand relative to a typical threshold, and treat what is treatable. If a deficit is unlikely to reach a required standard, knowing that months in advance is considerably more useful than finding out on the day.
Not by us. Our in-clinic locations are Chennai and Hyderabad and we do not maintain a Pune practice; claiming otherwise would be misleading. In practice this changes little, because the therapeutic programme runs remotely in full and the small number of procedures needing a physical examination are specified precisely so you arrange them once, locally, with a provider you choose. If you would like one in-clinic session and can travel, we will happily arrange it.
In selected cases, yes. It is not part of a routine amblyopia workup, but where a patient reports functional difficulty that acuity does not explain, contrast sensitivity frequently does. It is also a more sensitive index of change than acuity in adults, where acuity can plateau while the quality of the image continues to improve. We measure it when the presenting complaint and the acuity figure disagree.
By looking for a cause, not by assuming its absence. Amblyopia requires a history of an amblyogenic factor during the developmental window and a normal-appearing eye and optic nerve. Features that should prompt further investigation include a relative afferent pupillary defect, reduced acuity with no plausible developmental cause, an unusual field defect, or acuity that deteriorates rather than remains stable. In those cases we ask for a dilated examination before proceeding.
