Consecutive Exotropia after Convergent Strabismus Surgery—Surgical Treatment ()
ABSTRACT
Purpose: In this study the results of consecutive exotropia surgical
treatment by using different surgical technics are presented. Methods: This
study included 34 patients, aged 21 to 47 years (mean 27.9), who underwent medial rectus muscle advancement alone or
in combination with medial rectus resection and/or lateral rectus recession.
The mean interval between original surgery and surgery for consecutive
exotropia was 8.5 years (range: 5.5 years to 14 years). Most of patients had 2
and more prior surgeries (73.5%) sold by an adduction deficit (47.06%).
Results: The overall mean preoperative exodeviation was 35.12 ± 10.13 PD.
Satisfactory alignment (within 10 PD of orthophoria) was achieved in 20
patients (58.8%) at 10 days after surgery and 24 patients (70.5%) at final 6-month follow-up. The most common
surgical procedures were unilateral MR advancement and LR
recession—47%. Conclusion: Medial rectus advancement is an effective method of
surgical treatment, especially in cases with adduction limitation, but the risk
of the eyelid fissure narrowing in cases of MRM advancement more than 5 mm
associated with resection is present. In our opinion for reducing this risk in
cases of XT with big angle of deviation, performing a smaller amount of advancement associated with recession of LRM can
prevent the development of a such complication.
