Study of emulsified silicon oil bubbles size after retinal detachment surgeries in patients with high grade myopia
High myopic patients after pars plana vitrectomy with silicon oil (SO) emulcification are in high risk of secondary silicon oil induced glaucoma development due to anatomical specifications of anterior chamber. 12 samples of SO emulsified bubbles were taken during SO removal to evaluate its size frequency and to compare with diameter of trabecular meshwork orifices. In all cases 60%-63% were bubbles of size 0,1 mkm. The most frequent size range of rest bubbles was 0,2-0,7 mkm. Considering that diameter of trabecular meshwork orifices ranges from 4 to 20 mkm the early detection of emulcified SO bubles with gonioscopy can be an indication to SO removal or exchange to prevent IOP elevation in high myopic patients after pars plana vitrectomy.
