A Prospective Study to Analyse the efficacy of Apraclonidine in Preventing Intraocular Pressure Rise After Neodymium: YAG (Nd-YAG) Laser Posterior Capsulotomy

Intraocular pressure rise is a common complication after neodymium:yttrium-aluminum-garnet (Nd-YAG) laser posterior capsulotomy. Although in most cases it is related to an inflammatory response, there are other possible mechanisms such as misdirection syndrome and pupillary block. The authors report two cases of pupillary block by vitreous prolapse after Nd-YAG laser posterior capsulotomy evaluated by ultrasound biomicroscopy (UBM). UBM allows to differentiate possible causes of intraocular pressure rising after laser capsulotomy even in cases of corneal opacity. It also allows to detect intraocular lens dislocation, sometimes associated with this situation. This is the first report that describes the characteristics of UBM images of this complication.

A Prospective Study

Background: The aim of the study is to investigate whether the circadian IOP rhythm can be influenced by combined cataract surgery with high frequency deep sclerotomy (HFDS) and whether intraocular pressure (IOP) can be significantly reduced by HFDS. Methods: In our study 10 patients were included, in whom 24 h IOP monitoring was installed before and after HFDS/cataract surgery using a Triggerfish. HFDS is a minimally invasive glaucoma surgery (MIGS). Results: After performed HFDS combined with cataract surgery, the IOP was reduced from 27.7 ± 2.11 mmHg to 14.4 ± 2.59 mmHg, which is highly significant (p < 0.001). The contact lens sensor (CLS) cosinor analysis pre- and postoperatively showed that the circadian rhythm is not influenced by the surgery, i.e., the circadian IOP rhythm did not show significant differences before and after surgery. Conclusions: HFDS combined with cataract surgery is a potent surgical method that can significantly reduce the IOP. However, the circadian rhythm cannot be changed by the surgery. The acrophase remained during the night in all patients.
