Phase coupling between eye and brain pulsations is bidirectional and modulated by the parasympathetic system – An fMREye study

Acta Ophthalmologica, EarlyView.
Abstract Purpose Physiological pulsations driven by cardiac, respiratory, and vasomotor activity are essential for solute transport within perivascular and perineural cerebrospinal fluid (CSF) pathways that support brain and eye clearance systems. Previous studies have shown that parasympathetic blockade significantly reduces ocular pulsation power and

Visual acuity is reduced with increasing central retinal thickness, but also with higher age and female sex in diabetic macular oedema

Acta Ophthalmologica, EarlyView.
Abstract Introduction The increasing number of patients with diabetes has increased the incidence of diabetic macular oedema (DME) with the accompanying risk of developing visual loss. The purpose of the present study was to describe the contributions of increased central retinal thickness (CRT) and other risk factors to the reduction in visual acuity ...

The effect of 1% tropicamide on central corneal thickness and intraocular pressure

African Vision and Eye Health
Background: Dilating the eye with tropicamide may alter the intraocular pressure (IOP) because of an obstruction of the iridocorneal angle, resulting in decreased aqueous outflow drainage.

Zeb2 Controls Retinal Physiological and Pathological Angiogenesis by Regulating Astrocyte Proliferation and Differentiation

Cell Proliferation, EarlyView.
During development, the oxygen‐sensitive transcription factor Zeb2 restrains astrocyte proliferation and maturation to ensure balanced retinal angiogenesis. In disease, it promotes the neurotoxic A1 astrocyte phenotype and inflammation, thereby promoting reparative revascularization over pathological neovascularization.

Bilateral simultaneous cataract surgery and intraocular lens implantation in an adult female chimpanzee (Pan troglodytes) inducing monovision

Veterinary Ophthalmology, Volume 28, Issue 2, Page 457-464, March 2025.
Abstract Background Cataract is the major cause of visual impairment in humans. Phacoemulsification with intraocular lens (IOL) implantation is the standard technique for cataract treatment with a high success rate. In a few cases, the surgical cataract procedure and lens implantation have been applied in non‐human primates.

Effectiveness of cyclopentolate 1% compared to the combination of cyclopentolate 1%, tropicamide 1%, and phenylephrine 10% in cycloplegic refractive examination

Journal of Clinical Ophthalmology and Research
Context: Refractive errors in children require appropriate eyeglass correction. Cycloplegic refraction is a method used to determine eyeglass prescriptions in children due to their high accommodative power.
