Purpose
To study role of Ultrasound Bio-microscopy (UBM) in pediatric cataract surgery
Setting
Tertiary eye hospital New Delhi India
Methods
A prospective cross-sectional study from Jan’19 to Jan’22 included
550 eyes of 280 children(<10yrs) with congenital/developmental cataract.
Preoperative examination& biometry was done under anesthesia.
35MHz UBM was done for morphology, white-to- white (WTW), sulcus-to-sulcus (STS)&bag- diameters (BD) measurement.
Results
Morphology using UBM in children(3.19±4.1yrs) was zonular (43.6%), total(28%), posterior subcapsular(11.2%), membranous(12%), anterior plaque(1.6%), posterior plaque(1.2%), posterior capsular defect(0.8%)& persistent fetal vasculature(1.6%). Mean WTW, STS&BD were 10.69±1.29, 10.19±1.15& 8.17±1.71 respectively. There was significant correlation of WTW with STS(p=0.03) but not BD. BD&STS had no correlation with age& axial length.
Conclusions
UBM helps in identifying unique morphology of pediatric cataract. Bag diameter is a novel parameter for planning IOL implantation.
