AI Article Synopsis

  • The study investigates the effects of an ethanolic extract of mycelium (CCME) from a medicinal mushroom on lowering intraocular pressure (IOP) in rat and rabbit models, potentially offering a therapeutic option for glaucoma.
  • Results indicated that CCME significantly reduced IOP by 60.5% after 56 days of administration and decreased retinal ganglion cell apoptosis by 77.2%.
  • The active component, N6-(2-hydroxyethyl)-adenosine (HEA), was effective in lowering IOP by 29.6% at a low dosage, with minor effects on the pMLC2 signaling pathway.

Article Abstract

(CC), an entomogenous fungus that has been reported to have therapeutic glaucoma, is a major cause of blindness worldwide and is characterized by progressive retinal ganglion cell (RGC) death, mostly due to elevated intraocular pressure (IOP). Here, an ethanolic extract of mycelium (CCME), a traditional medicinal mushroom, was studied for its potential in lowering IOP in rat and rabbit models. Data showed that CCME could significantly (60.5%) reduce the IOP induced by microbead occlusion after 56 days of oral administration. The apoptosis of retinal ganglion cells (RGCs) in rats decreased by 77.2%. CCME was also shown to lower the IOP of normal and dextrose-infusion-induced rabbits within 60 min after oral feeding. There were dose effects, and the effect was repeatable. The active ingredient, N6-(2-hydroxyethyl)-adenosine (HEA), was also shown to alleviate 29.6% IOP at 0.2 mg/kg body weight in this rabbit model. CCME was confirmed with only minor inhibition in the phosphorylated myosin light chain 2 (pMLC2) pathway.

A 40-year-old gravida 7 para 4+2 lady who was 14 weeks pregnant presented with a three-day history of sudden-onset flashes of light associated with a superonasal visual field defect on her right eye. She had two prior miscarriages that occurred in the second and third trimesters. Previous serological tests for antiphospholipid syndrome (APS) were normal.

An 18-year-old woman with a congenital iris stromal cyst was referred for sudden-onset increased intraocular pressure (IOP) that did not respond to medical therapy. Ultrasound biomicroscopy demonstrated synechial angle closure from 9:00 to 12:00 in addition to a large cyst occupying much of the inferior angle. After implantation of an Ahmed glaucoma valve, her visual acuity returned to baseline, and IOP normalized.

Background: To evaluate intrascleral plug stability and correct centring of the IOL in three different surgical techniques using intraoperative anterior segment OCT.

Methods: This retrospective scientific study was conducted by reviewing patient records from the Ophthalmology Unit at the Civico Hospital of Palermo, covering the period between 2021 and 2022. Three distinct groups of patients, each consisting of 7 eyes from 7 individual patients, were included in this study.

Retropupillary Iris Clip Intraocular Lenses: A Case Series of 57 Eyes.

Int Ophthalmol Clin

January 2025

Westmead and Central Clinical Schools, Specialty of Ophthalmology and Eye Health, The University of Sydney, Sydney, NSW, Australia.

Purpose: To report visual and refractive outcomes and intraoperative and postoperative complications after pars plana vitrectomy (PPV) with retropupillary implantation of an iris clip intraocular lens (IOL).

Methods: This is a retrospective case series of patients who underwent secondary retropupillary intraocular lens insertion combined with pars plana vitrectomy to treat aphakia secondary to a dislocated nucleus lens (group A); or IOL dislocation (group B). Patient demographics, preoperative visual and refractive outcomes, intraoperative factors, postoperative visual and refractive outcomes, and complications within the follow-up period ranging from 6 months up to 3 years postoperative, were recorded.

High intraocular pressure (HIOP) and high glucose levels are associated with oxidative stress. Although physical exercise protects against oxidative damage, its specific impact on eye health remains unclear. Thus, this study aimed to assess the impact of physical exercise on the oxidative status of whole eyes in male Swiss mice subjected to HIOP model and cafeteria diet (CD).
