The relationship between postoperative vision and preoperative stability of fixation with SLO microperimetry in patients treated with macular translocation surgery
Fujikado T., Tano Y.
Dept. Ophthalmology and Applied Medical Engineering Osaka University Medical School, Suita
Purpose: To investigate the relationship between postoperative
vision and preoperative stability of fixation evaluated by SLO.
Methods: Preoperative stability of fixation was assessed by calculating
the standard deviation (SD) of the coordinate of fixation points using
SLO microperimetry. Best corrected postoperative visual acuity was assessed
at least 6 months after surgery. Thirty two patients with either age related
macular degeneration (n=22) or myopic neovascular maculopathy (n=10) who
underwent macular translocation surgery were examined.
Results: Postoperative visual acuity was negatively correlated
with the SD of the coordinate of fixation points (r=-0.43, P=0.014; Pearson).
Conclusions: Although several factors may influence the surgical
outcome, the preoperative stability of fixation evaluated with SLO is
a useful parameter to predict the postoperative vision.
