Baerveldt-Baerveldt Apposition: A New Surgical Technique to Salvage Obstructed Glaucoma Drainage Tubes.

J Curr Glaucoma Pract 2019 Sep-Dec;13(3):110-112

Department of Ophthalmology, Glaucoma Research Center, Montchoisi Clinic, Swiss Visio, Lausanne, Switzerland.

Aim: Glaucoma drainage device (GDD) failure is usually rectified by the replacement of the entire device or using a tube extender, both of which were associated with postoperative complications. To minimize these risks, we developed a technique to replace the failing section of a tube while keeping the filtration plate in place, and without resorting to an extender clip.

Background: We describe the case of a 69-year-old man, whose left posttraumatic glaucoma was initially treated with a XEN-augmented Baerveldt procedure. Read More

Blebophthalmos: proptosis due to a massive bleb following implant surgery in refractory paediatric glaucoma.

BMJ Case Rep 2020 May 13;13(5). Epub 2020 May 13.

VST Center for Glaucoma Care, LV Prasad Eye Institute, Hyderabad, India

A 5-year-old boy with failed combined trabeculotomy and trabeculectomy underwent Ahmed glaucoma valve (AGV) implantation and presented 5 weeks postoperatively, with sudden onset proptosis downward displacement of the globe, limited extraocular movements and displacement of tube from anterior chamber. CT scan of the orbits showed a large cystic bleb with posterior dislocation of the implant and was explanted. In vitro testing of implant for fluid flow characteristics revealed a dysfunctional valve with anterior leak, which could have possibly lead to anterior and inferior fluid accumulation resulting in displacement of implant, a probable cause for this rare complication.

Innovative usage of the remaining portion of Ahmed glaucoma valve tube as an implant in nonpenetrating glaucoma surgery.

Oman J Ophthalmol 2020 Jan-Apr;13(1):40-42. Epub 2020 Feb 17.

Eye Research Center, Mashhad University of Medical Sciences, Mashhad, Iran.

With the advent of nonpenetrating glaucoma surgeries (NPGS), these techniques are noticed more considerably by glaucoma surgeons due to lower complications in comparison to penetrating surgeries with comparable outcomes. One of the main objectives in these surgeries is the creation of an intrascleral filtering space as an alternative for subconjunctival filtering bleb. Intrascleral fibrosis in the long term reduces the volume of intrascleral bleb, so the use of implants as a space holder for preventing the collapse of scleral flaps and continued aqueous humor drainage is recommended.

Update in Genetics and Surgical Management of Primary Congenital Glaucoma

Turk J Ophthalmol 2019 12;49(6):347-355

University of Illinois at Chicago, Department of Ophthalmology and Visual Sciences, Chicago, USA

Primary congenital glaucoma (PCG) continues to be an important cause of visual impairment in children despite advances in medical and surgical treatment options. The progressive and blinding nature of the disease, together with the long lifespan of the affected population, necessitates a thorough understanding of the pathophysiology of PCG and the development of long-lasting treatment options. The first part of this review discusses the genetic features and makeup of this disorder, including all currently identified genetic loci (GLC3A, GLC3B, GLC3C and GLC3D) and relevant protein targets important for trabecular and Schlemm canal dysgenesis.

Dobutamine reverses the cardio-suppressive effects of terlipressin without improving renal function in cirrhosis and ascites: a randomized controlled trial.

Am J Physiol Gastrointest Liver Physiol 2020 02 16;318(2):G313-G321. Epub 2019 Dec 16.

Department of Gastroenterology and Hepatology, Odense University Hospital, Odense, Denmark.

Acute kidney injury and hepatorenal syndrome (HRS) are frequent complications in patients with cirrhosis and ascites. First-line treatment is terlipressin, which reverses HRS in ~40% of patients but also lowers cardiac output (CO). We aimed to investigate whether reversing the cardio-suppressive effect of terlipressin with the β-adrenoceptor agonist dobutamine would increase CO and thereby increase the glomerular filtration rate (GFR).

Eye (Lond) 2020 Feb 10;34(2):263-270. Epub 2019 Dec 10.

Department of Veterinary Medicine, University of Cambridge, Madingley Road, Cambridge, UK.

Filtration surgery has, for the past 50 years been key in the treatment of glaucoma yet a significant issue in the long-term success of such surgery is fibrosis limiting aqueous drainage. Numerous methods have been used to reduce such scarring after filtration surgery and animal models have been important in the development of such techniques. First animal models have been central in understanding molecular and cellular changes occurring in fibrosis and thus which pathways might be valuable therapeutic. Read More
