In a small clinical study the author evaluates the efficiency of the hemi-hangbackrecession (retroposition) procedure. This surgical procedure, which weakensextraocular muscles, proceeds from the hangback recession (retroposition) technique(hanging the muscle on a resorbable suture), which combines with thetraditional recession. Hemi-hangback recession procedure is suitable in caseswhen a recession of more than 7 mm is needed.It is experimentally and clinically as well demonstrated in extra large recessions,that a shift towards the original insertion of the muscle occurs. The combinationof the classical and hangback recession has its advantages in specific indications.More convenient surgical access and a reduction of the objectionable shift of themuscle backwards are main advantages of this procedure.The surgical procedure is described in this article and results in the group ofpatients from the Children’s and Adult’s Department of Ophthalmology at theFaculty Hospital in Motol, Prague, Czech republic. The hemi-hang-back musclesrecession is indicated in third and sixth nerve palsies, restrictive forms of strabismusand complicated or successive forms of strabismus.
Key words: hemi-hangback recession, hangback recession, extraocular muscle,weakening procedure, migration of the muscle
