Ultrasound biomicroscopy of the lacrimal drainage system
Al-Faky evaluated lacrimal sac (LS) pump failure in 17 patients with lower motor neuron facial nerve palsy using ultrasound biomicroscopy (UBM).
Anatomical patency was confirmed through irrigation of the lacrimal drainage system. UBM evaluation of the LS during opening and closure of the eyelids was performed for both sides. LS showed obvious fluid turbulence within the sac during opening and closure of the eyelids on the normal side. Fluid turbulence was absent in severe LS and reduced in the milder LS. The authors conclude that UBM can be used as a safe and non-invasive tool to evaluate the LS pump.
Glaukos iSTENT combined with phacoemulsification
Arriola-Villalobos et al conducted a prospective, non-comparative, interventional study to assess the mid-term efficacy and safety of the GTS-400-iStent combined with phacoemulsification in 20 patients with cataract and open-angle glaucoma or ocular hypertension. At 1 year follow-up, mean IOP decreased by 36% (9.4±3 mm Hg) from baseline washout IOP. Mean …
