Surgical peripheral iridotomy creation during intraocular surgery by intraocular diathermy probe-a novel technique.

A novel technique for the creation of surgical iridotomies using a bipolar diathermic probe is described. In a cohort comprising 19 eyes of 18 patients, a 100% patency rate was achieved, with no intra- or postoperative complications.

Visual hallucinations in Parkinson's disease are associated with thinning of the inner retina.

Visual hallucinations (VH) are common in patients with Parkinson's disease (PD), yet the underlying pathophysiological mechanisms are still unclear. We aimed to explore the association of the presence of VH with inner retinal thinning and, secondarily, with visual acuity. To this end, we included 40 PD patients in this exploratory study, of whom 14 had VH, and 22 age- and sex-matched healthy controls.

Diplopia in Parkinson's disease: visual illusion or oculomotor impairment?

Introduction: Approximately 20% of patients with Parkinson's disease (PD) experience diplopia; however, the cause of the diplopia is unclear. We aimed to explore the association of diplopia, and its subtypes, with oculomotor abnormalities, impaired vision, and visual hallucinations, in patients with PD.

Methods: This exploratory study included 41 PD patients, recruited from two general hospitals, of whom 25 had diplopia and 16 did not have diplopia, as well as 23 healthy controls (HCs).

In vivo exploration of retinal nerve fiber layer morphology in Parkinson's disease patients.

Thinning of the retinal nerve fiber layer (RNFL) is a recently discovered feature of Parkinson's disease (PD). Its exact pathological mechanism is yet unknown. We aimed to determine whether morphological changes of the RNFL are limited to RNFL thinning or also comprise an altered internal structure of this layer.

Subconjunctival injection of low-dose Mitomycin-C for treatment of failing human trabeculectomies.

Purpose: To evaluate the safety and efficacy of a low-dose Mitomycin C injected subconjunctivally after a guarded filtration operation in humans.

Methods: Fourteen patients with failing filters received an injection of 0.01 mg Mitomycin C (0.
