Study Summary

Different methods was tried to treat high AC/A strabismus cases;such as prescription of bifocal glasses in esotropia,recession of horizontal muscles with posterior fixation sutures,more recession than needed for far deviation(augmented recession),recession and pulley fixation and slant recession.

Different results was reported for any type of above methods. In recent studies,slanted recession was applied for high AC/A in esotropic cases and success rate of 67% was reported.but there was no unanimity for procedure of choice.

Since slant recession method is simpler and has low side effect than the other methods,therefore in this study the investigators want to peruse the outcome of this method on high AC/A horizontal strabismus.
