LONG-TERM RESULTS OF SURGERY FOR SUPERIOR OBLIQUE PALSY

The results one month after surgery in 159 cases of superior oblique p alsy were compared according to the method of surgery with the results 4 years or longer after surgery. There were 141 cases of congenital p alsy and 18 cases of acquired palsy, for a total of 159 cases. Our stu dy showed that surgery on the oblique muscle provided long-lasting eff ects, while recession of the superior rectus muscle or recession of th e contralateral inferior rectus muscle could cause late overcorrection . When performing surgery on the rectus muscle, careful attention must be paid to suturing the muscle.
