The Increased Burden of Rare Variants in Four Matrix Metalloproteinase-Related Genes in Childhood Glaucoma Suggests a Complex Genetic Inheritance of the Disease.

Childhood glaucoma encompasses congenital and juvenile primary glaucoma, which are heterogeneous, uncommon, and irreversible optic neuropathies leading to visual impairment with a poorly understood genetic basis. Our goal was to identify gene variants associated with these glaucoma types by assessing the mutational burden in 76 matrix metalloproteinase-related genes. We studied 101 childhood glaucoma patients with no identified monogenic alterations using next-generation sequencing.

Objective: To describe the inheritance pattern and clinical variability of primary congenital glaucoma (PCG) in a family with two affected siblings.

Materials And Methods: Two sisters diagnosed at birth with bilateral PCG, whose father had bilateral PCG and mother had bilateral microphthalmus, were subjected to a familial genetic study and ophthalmologic follow-up including intraocular pressure (IOP) measurement, and collection of biometric and cup-to-disc ratio data.

Results: The inheritance pattern was autosomal recessive in compound heterozygosis.

Effectiveness and safety of XEN63 in patients with primary-open-angle glaucoma.

This paper evaluates the effectiveness and safety of XEN63 stent, either standalone or in combination with phacoemulsification, in patients with primary open-angle glaucoma (POAG). Eighty eyes from 80 patients with medically uncontrolled POAG were assigned to undergo XEN63 implant. The primary outcome was the surgical success, defined as an intraocular pressure (IOP) lowering from preoperative values ≥ 20% and an IOP absolute value between 6 and 18 mmHg, with or without antiglaucoma medications.
