Abstract: Squint or strabismus is an ocular condition in which an eye deviated from its normal position of parallelism we have different forms of squints 1 con 2 acquires one of the most important things while dealing with a squint is to do the following things 1. Visual assessment 2. Refraction mydriatic 3. Fundus examination Why funds as in children retinoblastoma and coats disease can present as squint urge we have got various forms of squint 1. Accommodate 2. Non Accommodative 11 paralytic non paralytic 11 concomitant non concomitant squint can be esotopia, exotropia, hypertropia, hypotripia, pseudotropia, hertrotropia, microtropia and cyclotropia.
Introduction: Bil alternating infantile tropia can present as 1. Crossed fixation 2. In crossed fixation 3. A v pattern 4. Broad angle 5. Over action of Inf oblique 6. Covering the dominant eye will make the child to cry.
Case Report: 6 months old twins were seen by me in 2002 with parents having noticed bil alternate inward ocular deviation since 3 months on examination both twins had 20 to 25 degrees bil alternating esotopia f t normally delivered children no other cong abnormalities present ocular movements full and within normal limits mydriatric refraction ant segment and fundii normal both twins no evidence of abnormal head posture or ocular torticolis so under gain both twins bil 5mm medial rectii recessions was done after exposure of eye with eye sprculm rotation of eye balls was done with 6 zero silk sutures passed at 6 and 12o clock positions respectively isoloation of medial rectii was done through limbal based conjuctival aproach 5 mm recessions of medial rectii was done and position of produces asatisfactory correction of angle of squint but it produces
minimal eye reaction as in recession we do not cut muscle so reaction is less however there are few complications associated with this procedure not serious but they are as follows 1 under correction 21 amblyopia over action of inferior oblique medial rectii was secured on sclera using 6 zero vicoryl sutures then conjuctival reposition was done post operatively there was a very satisfactory correction of angle of squint with minimal eye reaction discussion medial rectii recessions for bil alt inf esotopia is a n operative modality of choice even after more than 15 years same procedure is done these days conclusion medial rectii recessions for bil alt esotopia not only produces a satisfactory correction of angle of squint but the eye reaction is minimal as in recessions as we do not cut muscles the eye reaction is minimal howevross few complicationser we do come ross few post-operative complications as
1. Under correction
2. Amblyopia
3. Over action of Inf. oblique
4. Accomodative element
5. DVD (Dessociated Verticle Deviation).
