  • Title: [Effect of axial bulbus length and preoperative squint angle on the effect of horizontal combined squint operations].
    Author: Gräf M, Krzizok T, Kaufmann H.
    Journal: Ophthalmologe; 1994 Feb; 91(1):62-7. PubMed ID: 8173253.
    Abstract:
    We studied the influence of axial bulbus length on the effect of the recession/resection procedure in 175 patients and found a significant negative correlation between the axial length and surgical effect in 62 esotropic patients undergoing surgery of various degrees. A poor correlation was found in 69 exotropic patients. In a group of 54 patients who underwent recession/resection surgery for esotropia with 5 mm recession of the medial rectus muscle and 7 mm resection of the lateral rectus muscle there was a highly significant correlation between the axial length and effect. There was also a significant correlation between the angle of the preoperative deviation and the response to surgery in the esotropic groups. To reduce the variability of strabismus surgery the bulbus length should be taken into consideration, at least in recession/resection procedures when the surgery exceeds 10 mm.
