Reviving XEN63 Gel Stent Patency in Uveitic Glaucoma: A Novel Approach Using 10-0 Nylon Probe.

Purpose: This case report describes the possibility of XEN63 lumen obstruction at the middle of the device and emphasizes the potential to restore its flow using an ab-externo revision technique involving a 10-0 nylon suture probe, before considering more aggressive surgical interventions.

Methods: A 55-year-old female with uveitic glaucoma underwent XEN63 implantation but experienced elevated intraocular pressure (IOP) (35 mm Hg) 1 month after the operation, despite medical therapy. A flat bleb, lack of response to medication, yttrium aluminum garnet (YAG) laser treatment, and slit-lamp needling necessitated revision.

[First isolation of Acanthamoeba spp. in seawater from the southeast of Buenos Aires (SE, Argentina)].

Free-living amoebae (FLA) of the genus Acanthamoeba are ubiquitous and amphizoic protozoa that colonize aquatic and terrestrial habitats and can serve as reservoirs for other microorganisms. They are considered econoses that can cause severe and rare pathologies. Due to limited epidemiological data available, the objective of this study was to investigate the presence of Acanthamoeba in coastal wetlands of the southeast of Buenos Aires province and evaluate their association with bacteriological and environmental variables.

Dominant p.Ser740* Pathogenic Variant in 20 Knowingly Unrelated Families Affected by Rod-Cone Dystrophy: Potential Founder Effect in Western Sicily.

. Retinitis pigmentosa (RP) is the most common inherited rod-cone dystrophy (RCD), resulting in nyctalopia, progressive visual field, and visual acuity decay in the late stages. The autosomal dominant form (ADRP) accounts for about 20% of RPs.

UNILATERAL MACULAR HOLE IN A PATIENT WITH RETINITIS PIGMENTOSA TREATED WITH COVER FLAP TECHNIQUE WITH THE USE OF PLATELET-RICH PLASMA UNDER AIR TAMPONADE.

Purpose: The purpose of the study is to show the excellent anatomical result of the inverted flap-assisted technique with platelet-rich plasma under air for retinitis pigmentosa complicated with macular hole.

Methods: A 32-year-old woman, previously diagnosed with retinitis pigmentosa, was referred to our department complaining of decreased central vision in her left eye for 4 weeks. At the time of presentation, the optical coherence tomography and fundoscopy examination showed the presence of a macular hole of 620 μ m in diameter.

Novel homozygous variant underlying USH2-like phenotype of Usher syndrome.

Purpose: Usher syndrome (USH) is an autosomal recessive disorder characterized by congenital sensorineural hearing impairment and retinitis pigmentosa. Classification distinguishes three clinical types of which type I (USH1) is the most severe, with vestibular dysfunction as an added feature. To date, 15 genes and 3 loci have been identified with the gene being an uncommon cause of USH.

[Effect of temperature on the viability of Trichinella spiralis larvae].

The aim of this work was to study the effect of temperature on the viability of free and encysted larvae of Trichinella spiralis from southwest Buenos Aires province, Argentina. Larvae were treated at variable temperatures (-30 °C, -20 °C, 4 °C, 20 °C, gradual heating between 0-100 °C). The time necessary to kill 100 % of larvae was calculated.
