ABSTRACT
ABSTRACT: In this study 24 patients files, who underwent excessive recession of horizontal muscles operation between December 1992-March 2003 in Beyoglu Educational and Research Eye Hospital, were evaluated retrospectively. All patients were congenital motor nystagmus without blockage and nystagmus amplitude decrease at primary position and ages were between 2-28 years (mean 14,50 9,49 years). 5 of them have exotropia, 7 of them have esotropia, 2 of them were albinos. The preoperative and postoperative monocular and binocular mean visual acuity at near and distance and nystagmus amplitude biomicroscobically recorded. The differences were statistically significant. The excessive recession of horizontal muscles in surgical treatment of congenital nystagmus is effective for decreasing nystagmus amplitude and visual improvement.
