Results of the investigation of the oxyhaemoglobin content in the blood of the anterior ciliary veins in 23 patients with primary glaucoma and in 4 patients with senile cataract are presented. An extremely high content of oxyhaemoglobin in the anterior ciliary veins was revealed in all patients irrespective of the level of the intraocular pressure and the stage of the disease.

Purpose: To develop an artificial intelligence algorithm to automatically identify the anterior segment structures and assess multiple parameters of primary angle closure disease (PACD) in ultrasound biomicroscopy (UBM) images.

Design: Development and validation of an artificial intelligence algorithm for UBM images.

Methods: 2339 UBM images from 592 subjects were collected for algorithm development.

Introduction: Cataract surgery has been reported to have a reducing effect on intraocular pressure (IOP) in glaucomatous and non-glaucomatous eyes. This effect seems to be more noticeable in eyes with narrow angles (NAs) than in eyes with open angles (OAs). Decrease in IOP may be a result of the increase in anterior chamber angle (ACA) and Schlemm canal (SC) after cataract surgery.

Persistent hypotony following Tanito microhook trabeculotomy (TMH) is rare but may occur due to the development of cyclodialysis clefts. We report a case of a Japanese man in his 40s who developed persistent hypotony and hypotony maculopathy after TMH in the left eye. Fourteen months after the surgery, the patient was referred to our institution due to prolonged hypotony that remained undiagnosed and untreated despite evaluations with gonioscopy and anterior segment optical coherence tomography (AS-OCT) at the referring clinic.

Objectives: To evaluate the effects of short-acting cycloplegic agents, tropicamide and compound tropicamide, on ocular biological parameters and choroid thickness.

Methods: In this study, seventy pediatric subjects aged 6 to 13 years were randomly assigned to two groups: the tropicamide group and compound tropicamide group. Ocular biological parameters and choroidal thickness (CT) and subfoveal choroid thickness (SFCT) were measured in both groups and were retested 40 min after drug administration.

A pupil called Worry: Mydriasis in orbital surgery.

Clin Neurol Neurosurg

January 2025

Department of Ophthalmology, University Hospitals Leuven, Leuven, Belgium; Department of Neurosciences, Catholic University Leuven, Leuven, Belgium. Electronic address:

Objective: Surgeons routinely check the pupils to assess, in part, the brain stem function and the neural integrity of the visual system. Where a relative afferent pupillary defect is difficult to notice during surgery, an efferent pupillary defect or mydriasis is clearly recognizable. Visual loss in orbital surgery is attributed to compromised perfusion of the optic nerve, retina, or choroid, but an association with mydriasis is generally not assumed.
