The current method for implantation of the Ex-PRESS Glaucoma Filtration Device requires a conjunctival peritomy and shunt insertion under the guarded protection of a scleral flap. This technique requires suture closure of the flap and conjunctiva. A new minimally invasive technique for Ex-PRESS shunt implantation allows for insertion through a scleral tunnel originating from a grooved clear corneal incision. This new method avoids the need for conjunctival dissection and closure and offers the advantages of eliminating conjunctival wound leaks while maintaining the protection of a partial thickness scleral covering. This new technique may offer a faster safer means for shunt implantation with the potential for less conjunctival scarring.

Purpose Of Review: This review highlights new Federal Drug Administration (FDA) approved glaucoma treatments to familiarize providers with immediately available options.
Recent Findings: New FDA-approved treatments include the bimatoprost implant, travoprost implant, direct selective laser trabeculoplasty (DSLT), and ocular pressure adjusting pump. The bimatoprost implant is approved for a single administration with effects lasting for about 1 year, as opposed to the nearly 3-year effect for the travoprost implant.

Background Aims: Clinically-significant portal hypertension (CSPH) in liver cirrhosis patients can lead to refractory ascites. A transjugular-intrahepatic-portosystemic shunt (TIPS) treats CSPH but may cause overt hepatic encephalopathy (oHE). Our aim was to determine the optimal reduction of the portal pressure gradient (PPG) via TIPS to control ascites without raising oHE risk.

Background: NF2-related schwannomatosis (NF2) is associated with various tumors of the central and peripheral nervous system. There is a wide range of disabilities these patients may suffer from and there is no validated clinical classification for disease severity. We propose a clinical classification consisting of three severity grades to assist in patient management.
