Effect of anticholinergic eye drops on intraorbital, periorbital and brain pulsation power

Acta Ophthalmologica, EarlyView.
Abstract Purpose The study aims to investigate the effect of pharmacologically reducing parasympathetic activity on ocular and cerebral pulsations, inspired by recent discoveries of a glymphatic‐like system in the eye driven by physiological pulsations.

Muscle tendon elongation with bovine pericardium (Tutopatch®) in patients with Graves’ orbitopathy; a prospective, observational, multicentre study

Acta Ophthalmologica, EarlyView.
Abstract Purpose Patients with severe ocular motility restriction and/or large angle strabismus due to Graves' orbitopathy (GO) cannot be adequately addressed with conventional strabismus surgery using large muscle recessions. Muscle tendon elongation surgery, using a spacer of bovine pericardium (Tutopatch®) has emerged as a valuable alternative.

Image findings of cranial nerve pathology on [18F]-2- deoxy-D-glucose (FDG) positron emission tomography with computerized tomography (PET/CT): a pictorial essay. [PDF]

, 2015
This article aims to increase awareness about the utility of (18)F -FDG-PET/CT in the evaluation of cranial nerve (CN) pathology. We discuss the clinical implication of detecting perineural tumor spread, emphasize the primary and secondary (18)F -FDG-PET/

Factors associated with the high prevalence of myopia and its decrease—A historical review

Acta Ophthalmologica, EarlyView.
Abstract Purpose To review historical and recent studies on the epidemiology of myopia, identify the factors associated with its prevalence and determine how myopia has been successfully prevented. Methods Historical and recent publications were reviewed regarding factors associated with the prevalence of myopia and the success of myopia prevention ...

Investigating Microinvasive Intra‐Ocular Biopsy

Clinical &Experimental Ophthalmology, EarlyView.
ABSTRACT Background Current minimally invasive methods of intraocular biopsy are confined to small gauge (G) needles and subretinal cannulae that can be prone to wound leakage at the biopsy site. We investigate the role of microneedles with internal diameters as small as 49G for intraocular biopsy in the posterior and anterior segments.

Comparison of the effects of remifentanil and alfentanil on intraocular pressure in cataract surgery [PDF]

Background: Anesthesia for ophthalmic surgery requires management of intraocular pressure (IOP) during perioperative period. In an open eye, in conditions such as after traumatic injury or during cataract surgery, IOP increase can lead to permanent ...
