Supplementary Material for: Subfoveal Choroidal and Macular Thickness Changes after Phacoemulsification Using Enhanced Depth Imaging Optical Coherence Tomography
<p><b><i>Purpose:</i></b> To assess changes in the thickness of the
subfoveal retina and choroid after phacoemulsification using enhanced
depth imaging optical coherence tomography (EDI-OCT). <b><i>Methods:</i></b>
A prospective study was conducted on 100 patients. The subfoveal
choroidal thickness (SFCT) was measured at 7 points and the retinal
thickness was measured at 5 points (before surgery, and 1 day, 1 week, 1
month, and 3 months after surgery). <b><i>Results:</i></b> The foveal choroidal thickness showed a thickening trend (but <i>p</i>
> 0.05). Compared to the change from baseline to day 1, the changes
from baseline were significantly different at nasal 3 mm and 6 mm at all
other time points (all <i>p</i> < 0.05). Choroidal thickness changes
at temporal 6 mm correlated negatively with intraocular pressure (IOP)
at 1 week and 1 month; changes at nasal 3 mm correlated negatively with
IOP at 1 week and 1 month (all <i>p</i> < 0.05); changes at nasal 3
mm, temporal 3 mm, and temporal 6 mm correlated with average ultrasonic
energy. Choroidal thickness changes correlated with ultrasound (US) time
at day 1. <b><i>Conclusions:</i></b> Uncomplicated phacoemulsification
led to changes in choroidal thickness. IOP and choroidal thickness
changes were negatively correlated. The foveal retinal thickness was
correlated with age. SFCT was correlated with sex, axial length, IOP,
and US time.</p
