The aim of our study was to evaluate the results of the operation on squint with pathological attachment of lateral rectus revealed during surgery.
Material And Methods:
The study involved 22 children (12 girls and 10 boys) out of 320 children operated on for squint in the years 1993-1996, who had pathological attachment of lateral rectus. Alternating convergent squint was found in 12 children, unilateral in 10. Muscle exposure showed dislocation of lateral rectus attachment--upwards by c. 1.5 mm in 11 children, downwards and obliquely by c. 2 mm in 10 children, in 1 child the upper part of the attachment was shifted forward by 1 mm. During the surgery, in addition to the reduction of squint angle, physiological attachment of the rectus was reconstructed.
Results:
The operation restored parallel position of the eyes in 22 children, very good vision was obtained in 12 (54%) with alternating convergent squint, significant improvement in 5 (22%) with unilateral convergent squint, and only slight improvement in the remaining 5 (22.7%) with high initial amblyopia and squint angle from +15 degrees to +30 degrees.
