A closer look at the new wave of glaucoma surgery – radical or old school?

Glaucoma is a challenging condition to treat because the exact pathophysiology remains unclear and the only readily modifiable factor is the intraocular pressure (IOP). Additionally, most glaucoma patients are completely asymptomatic, yet are often subjected to lifelong medical therapy. The...

Chronic lymphocytic leukaemia (CLL) of the lacrimal sac

The authors present a case series of three patients with known CLL, two of which presented with mass and epiphora and one case with epiphora alone. All three patients had initially being diagnosed and were treated for chronic dacryocystitis. Histopathological...

Prism adaptation responses for variable distance-near deviation in intermittent exotropia

The purpose of this study was to evaluate the effect of the prism adaptation test (PAT) on angle and distance-near-deviation (DND) in intermittent exotropia (IXT), and determine the frequency of responders and non-responders to PAT. This was a single-centre study...

Contemporary glaucoma therapy: spoilt for choice

The goal of glaucoma management is to prevent visual loss and disease progression in the patient’s lifetime through effective lowering of intraocular pressure (IOP), the primary modifiable risk factor in glaucoma. Sustained and consistent IOP reduction is key to halting...

Esotropia Duane’s syndrome (DRS) surgery

The authors aimed to compare the safety and efficacy of augmented superior rectus transposition surgery with / without medial rectus (MR) recession versus MR recession along in the treatment of esotropic DRS. This was a prospective randomised trial of 20...

Introduction of the Mydriasert insert at the Manchester Royal Eye Hospital

The authors report on a study to examine the effects of the Mydriasert insert on time, effects, patient comfort and tolerability at Manchester Royal Eye Hospital. Mydriasert is an insoluble ophthalmic insert indicated for mydriasis prior to ophthalmic surgery, which...

Herpes zoster ophthalmicus: a clinician’s perspective

Introduction Herpes zoster, commonly known as shingles, is caused by the reactivation of varicella zoster virus (VZV). The term herpes is derived from a Greek work, herpein, which means ‘creeping’ and the word zoster means a belt or a girdle...

Farnborough International Airshow 2022 partners with Orbis UK

Farnborough International Airshow (FIA) announces Orbis UK as its official charity partner for 2022.

Fusion vergence measures

The purpose of this study was to compare fusional vergence measurements between orthophoria, esophoria and exophoria and determine the strength of correlation between fusional vergence and angle of deviation. This was a cross-section study of 530 children aged six to...

Fusional vergence measurement

This paper reports a systematic review to address two objectives: 1, to compare the normative values of tests measuring fusional vergence; 2, to investigate sources of heterogeneity of prism accuracy. The review was conducted according to PRISMA guidelines with a...

Ethnic variation in strabismus patterns in Down syndrome

The authors present a systematic review and meta-analysis evaluating the prevalence and aetiology of strabismus in individuals with Down syndrome, with particular focus on ethnic variation in the esotropia to exotropia ratio. Data from multiple studies across diverse populations were...

Changes in phoria measurements after physical activity

This study aimed to evaluate effects of physical activity (aerobic and anaerobic) on the latent eye deviation. The study recruited 20 competitive soccer players (10 myopes (mean -0.63D) and 10 emmetropic: 19 males), who underwent a total 90-minute exercise of...
