BMC Med Genet 2020 Jul 8;21(1):145. Epub 2020 Jul 8.

Department of Ophthalmology, College of Medicine, King Saud University, P.O. Box 245, Riyadh, 11411, Saudi Arabia.

Background: Glaucoma is a polygenic neurodegenerative disease and the second most common cause of blindness in Saudi Arabia. To test the hypothesis that genetic variants in the genes involved in the bone morphogenic protein (BMP) signaling pathway may be associated with glaucoma, we investigated the association between 3' untranslated region variants, rs12997 in ACVR1 and rs1043784 in BMP6, and primary angle-closure glaucoma (PACG) and pseudoexfoliation glaucoma (PXG).

Methods: In a case-control study, TaqMan® real-time PCR-based genotyping was done in 444 subjects consisting of 250 controls, 101 PACG and 95 PXG cases, and tested for genetic association with glaucoma-types and other clinical phenotypes. Read More

[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).

Evaluation of Tear Fluid and Aqueous Humor Concentration of Clusterin as Biomarkers for Early Diagnosis of Pseudoexfoliation Syndrome and Pseudoexfoliative Glaucoma.

Curr Eye Res 2020 Jul 29;45(7):805-813. Epub 2019 Nov 29.

Department of Ophthalmology, Gülhane Training and Research Hospital, University of Health Sciences , Ankara, Turkey.

Purpose: Pseudoexfoliation syndrome (PEX) is an age-related disorder of the extracellular matrix characterized by the accumulation of fibrillary deposits in the anterior chamber of the eye, which leads to the development of pseudoexfoliative glaucoma (PEG). Early identification of subjects with higher susceptibility to PEX and PEG development is very important so that these conditions are managed at earlier stages, which requires that an objective biomarker is defined. Therefore, in the present study, we aimed to determine if aqueous humor and tear fluid concentrations of clusterin, an extracellular chaperone, are objective biomarkers for PEX and PEG risk.

Pseudoexfoliation syndrome (PEX) may lead to the development of pseudoexfoliative glaucoma (PEG), a potential cause of irreversible blindness, if left untreated. This type of glaucoma often presents with much higher intraocular pressure (IOP) values than observed in primary open angle glaucoma, and patients are often unaware of their condition. Therefore, early diagnosis is of utmost importance in PEX and PEG. Read More
