Fifty-four eyes of 45 patients with ocular hypertension developed early glaucomatous optic disc or visual field changes after a mean follow-up of 5.1 years without therapy. These changes initiated antiglaucomatous treatment, and the eyes have been followed further on therapy for 2-14 years (mean 8.0 years) in a retrospective study. The mean intraocular pressure (IOP) was lowered from 28.9 to 19.3 mmHg. Half of the eyes were still without field defects at the end of the study, whereas 7 eyes developed extensive field damage noticeable to the patients. The eyes with deteriorating visual fields could not be differentiated from the stable ones by means of the pre-therapy IOP, nor the mean or peak IOP on treatment. There was an accumulation of topical and general risk factors in the progressive eyes. The results support the importance of taking other risk factors than the IOP into consideration in the management of our glaucoma patients.

Objective: To report ophthalmic complications associated with the use of semaglutide or tirzepatide.
Fall rates in bifocal, trifocal, and progressive addition lens glasses wearers.
Optom Vis Sci

Department of Aged Care and Rehabilitation, Royal North Shore Hospital, Sydney, New South Wales, Australia.
Purpose: There is evidence that wearing multifocal glasses increases the risk of falls in older people, especially when walking on stairs and in unfamiliar settings. However, it is not clear whether all types of multifocal glasses are equally associated with falls. This study comprised a secondary analysis of data from the VISIBLE randomized controlled trial to determine whether fall rates differ among older bifocal, trifocal, and progressive addition lens glasses wearers.

Endoscopic cyclophotocoagulation (ECP) offers a viable alternative for managing advanced primary open-angle glaucoma (POAG) in patients at risk of ocular hypotony. We describe a case of a successful outcome with ECP in a patient who developed ocular hypotony secondary to Preserflo surgery. A 93-year-old South Asian male experienced significant visual field deterioration and ocular hypotony following Preserflo surgery on the left eye, complicated by a severe cough from COVID-19.

Background: Obsessive-compulsive disorder (OCD) is a complex condition marked by persistent distressing thoughts and repetitive behaviours. Despite its prevalence, the mechanisms behind OCD remain elusive, and current treatments are limited. This protocol outlines an investigative study for individuals with OCD, exploring the potential of psilocybin to improve key components of cognition implicated in the disorder.

A juxtapapillary retinal capillary hemangioma (JRCH) is a rare vascular hamartoma located on the optic nerve head or adjacent region. While often associated with von Hippel-Lindau (VHL) disease, JRCHs can also occur as an isolated condition, presenting unique therapeutic challenges and risks of visual impairment. We report a case of a 50-year-old Malay gentleman with diabetes mellitus who presented with a non-progressive superior visual field defect in his left eye for three months.
