Age-dependent regional retinal nerve fibre changes in SIX1/SIX6 polymorphism.

SIX1/SIX6 polymorphism has been shown to be associated with glaucoma. Studies have also found that, in older adults, retinal nerve fibre layer (RNFL) thickness is significantly thinned with each copy of the risk allele in SIX1/SIX6. However, it is not known whether these genetic variants exert their effects in younger individuals.

Identification and activity of the functional complex between hnRNPL and the pseudoexfoliation syndrome-associated lncRNA, LOXL1-AS1.

Individuals with pseudoexfoliation (PEX) syndrome exhibit various connective tissue pathologies associated with dysregulated extracellular matrix homeostasis. PEX glaucoma is a common, aggressive form of open-angle glaucoma resulting from the deposition of fibrillary material in the conventional outflow pathway. However, the molecular mechanisms that drive pathogenesis and genetic risk remain poorly understood.

Gray Optic Disc Crescent: Evaluation of Anatomic Correlate by Spectral-Domain OCT.

Purpose: To test the hypothesis that the anatomic correlate of the gray optic disc crescent is pigmentation of externally oblique border tissue of Elschnig.

Design: Retrospective study.

Participants: African-American adult men with or without clinically apparent gray optic disc crescents.

Association between Chronic Obstructive Pulmonary Disease and Exfoliation Syndrome: The Utah Project on Exfoliation Syndrome.

Purpose: Exfoliation syndrome (XFS) is associated with genetic variants of lysyl oxidase-like 1 (LOXL1), a key enzyme in the stabilization of extracellular matrix (ECM) and elastin, and in connective tissue repair. Because patients with chronic obstructive pulmonary disease (COPD) have increased and altered elastin degradation, an association between XFS and COPD was hypothesized and analyzed. Impact of XFS on survival in patients with COPD was evaluated.
