简要总结
V pattern strabismus is the commonest of alphabet pattern. Its identification is essential to plan a proper surgical management. Graded recession is a very logical approach to treat inferior oblique overaction (IOOA). The aim Is to evaluate the efficacy of graded recession of inferior oblique muscle for correction of different grades of V pattern.
详细描述
prospective interventional study for forty patients with V pattern strabismus and primary inferior oblique overeaction will be evaluated by prism cover test to assess the grade of IOOA and amplitude of V-pattern. Graded recession of IO muscle depends on the amplitude of the V-pattern and degree of IOOA. Eight mm recession for amplitude 7.5 to 10 degree and mild IOOA (10 or +1) ,10 mm recession for amplitude 11- 15 degree and moderate IOOA (11-15 or +2) and maximum recession for amplitude more than 15 degree and marked IOOA ( more than 15 degree or +3). Simultaneous correction of the horizontal deviation will be performed at the same sitting. Follow up after I week,1 month ,3 month and 6-month.
