Surv Ophthalmol 2020 May 22. Epub 2020 May 22.

Save Sight Institute, Faculty of Medicine and Health, University of Sydney; Sydney Eye Hospital, Macquarie St, Sydney, Australia.

Trabeculectomy has been performed since the mid-1960s and remains the gold standard for glaucoma surgery. Newer surgical options have evolved, collectively referred to as minimally invasive glaucoma surgeries (MIGS). Despite producing large intraocular pressure decreases, full-thickness procedures into the subconjunctival space may be limited by fibrosis. 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.

Needling after trabeculectomy - does augmentation by anti-metabolites provide better outcomes and is Mitomycin C better than 5-Fluoruracil? A systematic review with network meta-analyses.

Acta Ophthalmol 2020 Apr 30. Epub 2020 Apr 30.

CPAMD8 loss-of-function underlies non-dominant congenital glaucoma with variable anterior segment dysgenesis and abnormal extracellular matrix.

Hum Genet 2020 Apr 9. Epub 2020 Apr 9.

Área de Genética, Facultad de Medicina de Albacete, Universidad de Castilla-La Mancha, Albacete, Spain.

Abnormal development of the ocular anterior segment may lead to a spectrum of clinical phenotypes ranging from primary congenital glaucoma (PCG) to variable anterior segment dysgenesis (ASD). The main objective of this study was to identify the genetic alterations underlying recessive congenital glaucoma with ASD (CG-ASD). Next-generation DNA sequencing identified rare biallelic CPAMD8 variants in four patients with CG-ASD and in one case with PCG. Read More

Treatment of glaucoma by prostaglandin agonists and beta-blockers in combination directly reduces pro-fibrotic gene expression in trabecular meshwork.

J Cell Mol Med 2020 May 8;24(9):5195-5204. Epub 2020 Apr 8.

GROW Research Laboratory, Narayana Nethralaya Foundation, Bangalore, India.

Prostaglandin analogues (PG), beta-blockers (BB) or their combination (PG+BB) are used primarily to reduce the intraocular pressure (IOP) pathologically associated with glaucoma. Since, fibrosis of the trabecular meshwork (TM) is a major aetiological factor in glaucoma, we studied the effect of these drugs on fibrosis-associated gene expression in TM of primary glaucoma patients. In the present study, TM and iris of primary open-angle (n = 32) and angle-closure (n = 37) glaucoma patients were obtained surgically during trabeculectomy and categorized based on the type of IOP-lowering medications use as PG, BB or PG+BB.

[Signs of proliferative process after laser treatment of advanced glaucoma].

Vestn Oftalmol 2020 ;136(1):36-41

S.N. Fyodorov National Medical Research Center "MNTK "Eye Microsurgery", 59A Beskudnikovsky Blvd., Moscow, Russian Federation, 127486.

The universally established method for effective and less-invasive reduction of the intraocular pressure (IOP) in patients with primary open-angle glaucoma (POAG) is a two-step method consisting of non-penetrating deep sclerectomy (NDSE) followed by laser goniopuncture of the Descemet's membrane (Descemet's goniopuncture; DGP). However, the hypotensive effect can diminish at different times during the follow-up due to excessive scarring in surgically formed outflow tracts (SFOT).

Purpose: To evaluate the condition of SFOT in dynamics with Visante OCT after one-step combined laser technique consisting of modified selective laser activation of the trabecula (MSLAT) and DGP in advanced POAG patients with normalized IOP who have pronounced pigmentation of the trabecular meshwork and stage II pseudoexfoliation syndrome (PES).

[Biomechanical properties of the cornea as predictors of the effectiveness of selective laser trabeculoplasty].

Ophthalmological Center of the Federal Medical-Biological Agency of the Russian Federation, A.I. Burnazyan Federal Medical and Biophysical Center of FMBA, 15 Gamalei St., Moscow, Russian Federation, 123098.

Purpose: To study the changes in central corneal thickness (CCT) and corneal hysteresis (CH) after selective laser trabeculoplasty (SLT) in primary open-angle glaucoma (POAG) and primary angle-closure glaucoma (PACG) after laser peripheral iridotomy (LPI) and to determine their effect on the prognosis of the surgery.

Material And Methods: The prospective study involved 68 eyes with initial PACG after LPI and 74 eyes with initial POAG observed for 6 months. Corneal-compensated IOP (IOPcc), corneal resistance factor (CRF), CH and CCT were studied as the predictors of SLT, which was considered successful when IOPcc decreased by 20% or more from the baseline without additional hypotensive therapy and/or repeated SLT.
