Pattern one
Operated, discharged, never tested
Alignment good, everyone satisfied, stereoacuity unknown. A ten-minute measurement establishes whether there is anything left to recover, and often there is.
Families are usually offered squint treatment in terms of how the eyes will look, and that is a legitimate goal. It is not the only one. Whether the brain combines the two images afterwards determines depth perception and reading comfort for the rest of a life, and it is measured far less often. We assess and treat that, by secure telehealth, without travel out of the state.
Kolkata and Greater Kolkata
Surgical squint care is well established here. What has been harder to access locally is the sensory work that should follow it, and that is the gap a remote programme closes cleanly.
Pattern one
Alignment good, everyone satisfied, stereoacuity unknown. A ten-minute measurement establishes whether there is anything left to recover, and often there is.
Pattern two
An intermittent deviation reviewed annually, unchanged each time, with no control grading recorded. Nothing prompts a change of plan because nothing is being measured.
Pattern three
A child who is fine until the last hour of tuition, then loses the line, rubs the eyes or shows a drift. Attributed to tiredness; frequently a control problem.
Kolkata enquiries come from
We write to your ophthalmologist or surgeon with our measurements. This is adjunctive care and we are explicit with them about what we are and are not doing.
It is entirely reasonable for a family to want a child’s eyes to look straight. It is worth knowing that this is a narrower goal than the one most parents assume they are buying.
Alignment is achieved by repositioning muscles, and it is judged by looking. Binocular function is achieved by the brain learning to fuse two images, and it is judged by measuring stereoacuity. Surgery reliably delivers the first. It creates the conditions for the second without guaranteeing it.
The reason to be explicit about this is that the second goal has a time window and the first does not. Fusion potential is most recoverable in the year after alignment; appearance can be revised at any age. A family that knows both facts makes a different sequence of decisions than one that knows only the first.
Ask your surgeon what stereoacuity they would expect after the operation, and what would need to happen to achieve it. It is a fair question, it has a real answer, and it makes explicit whether the sensory half of the treatment has been planned or simply assumed.
A weekly live session with fifteen to twenty minutes of daily home practice, scheduled around school and tuition hours.
The first consultation
The full measurement set taken locally rather than on a journey out of state: angle at distance and near, control grading, refraction and stereoacuity, documented so none of it needs repeating.
Refraction and adaptation
Correction confirmed and coordinated with a dispensing optician of your choosing, with the adaptation interval allowed for rather than compressed.
The therapy programme
Fusion and anti-suppression work in short daily blocks around school and the tuition hours after it, with one supervised session weekly to raise the demand.
Follow-up and discharge
Remeasurement at session eight and a structured taper with three- and six-month reviews, giving continuity that previously required repeated out-of-state travel.
Post-surgical sensory work is a distinct treatment, not a continuation of the surgical follow-up. It has to be asked for.
Worth assessing, certainly; worth committing to depends on what we find. The first post-operative year is the most productive period, and five years out the odds are lower and the programme longer. But the variable that actually predicts response is current stereoacuity and suppression depth, not elapsed time. If a measurable degree of fusion potential remains, work is justified. If suppression is dense and stereoacuity is absent, we will tell you the expected gain is small rather than take you through six months to find out.
For the surgical decision, an in-person examination matters and local surgical care in Kolkata is capable. For the sensory half — suppression testing, fusion training, stereoacuity work — the whole programme is deliverable over video, and it needs weekly contact for months, which is exactly what repeated out-of-state travel makes impossible. Our usual recommendation is that you keep the physical examinations local and let the long, frequent part of the treatment happen at home.
It can be, but it should be an informed decision rather than a default. Observation is reasonable when the deviation is small, control is good and the sensory status is normal — and the last of those three is what usually has not been checked. If stereoacuity is intact and control is graded as good, watching is defensible. If there is suppression even in a slight turn, then something is being lost while you watch, and a short course of fusion work is a modest intervention against that.
They relocate the image rather than correct the deviation, which is useful for some purposes and not for others. In an adult with double vision from a small stable deviation, prisms restore single vision and can be an adequate long-term answer. In a child with developmental strabismus, they do not build fusion and are generally used as a temporary measure within a wider plan rather than as the plan itself.
Sometimes, and it depends on what the deviation was costing. A child suppressing one eye is reading effectively with one eye, which is workable for short passages and tiring over longer ones. Where reading difficulty stems from that, restoring comfortable binocular function helps with stamina rather than with decoding. If the difficulty is phonological, this will not address it, and we would say so rather than let therapy be tried as a substitute.

Delivered to Kolkata by secure telehealth — in-person prism testing at our Chennai and Hyderabad clinics.
A telehealth assessment records suppression and stereoacuity alongside the angle, and tells you whether sensory recovery is realistically available. No travel out of West Bengal.
