Unique case of steroid-induced intraocular pressure spike causing NAION

The literature describes previous cases of nonarteritic anterior ischaemic optic neuropathy (NAION) following rapid rises in intraocular pressure (IOP) leading to reduced optic nerve head perfusion and disruption. This is commonly following ophthalmic procedures, acute glaucoma or steroid eye drops....

IOL power calculation formulas for myopic eyes undergoing cataract surgery after excimer laser

The authors set out to compare the accuracy of four no-history formulas: Barrett True-K, Haigis-L, Shammas-PL, and Triple-S to calculate the intraocular lens (IOL) power in eyes with previous myopic photorefractive keratectomy or laser in situ keratomileusis, according to their...

The effects of ab-interno XEN gel implantation on postural IOP elevations

The study involved 18 patients with XEN gel implants, 30 patients who had trabeculectomy, and 30 medically managed glaucoma patients. All patients in XEN gel implant and trabeculectomy groups had at least 11 months of follow-up following successful surgery resulting...

Trabeculectomy with MMC in post-traumatic angle recession glaucoma

This study aimed to evaluate the outcomes of primary trabeculectomy with mitomycin-C (trab MMC) in phakic eyes with post-traumatic angle recession glaucoma with no prior intraocular surgery. Thirty-two phakic eyes of 32 patients who underwent trab MMC between January-2002 and...

Blood pressure association with primary open angle glaucoma severity

This prospective observational study involved 47 patients diagnosed with primary open angle glaucoma (POAG) examined to investigate their postural blood pressure response and its potential correlation with the severity of glaucomatous optic neuropathy (GON). Participants underwent intraocular pressure and systemic...

Comparison of paediatric migraine and healthy controls using optical coherence tomography angiography

The authors present a cross-sectional study which recruited patients with paediatric migraine without aura along with age and sex-matched healthy controls. Both groups were recruited following attendance to an ophthalmology outpatient clinic. Children diagnosed with any of the following were...

Selective laser trabeculoplasty after medical treatment

Selective laser trabeculoplasty (SLT) is a well-established treatment for open-angle glaucoma (OAG) and ocular hypertension (OHT). This post-hoc secondary analysis of the LiGHT trial extension examined SLT as a secondary intervention after 3 years of protocolised medical therapy in patients...

Incidence of high IOP following corneal collagen cross-linking

This retrospective cohort study examined 405 patients (405 index eyes and 218 untreated fellow eyes) who underwent cross-linking over a 12-year follow-up duration at Duke Eye Center. Preoperative and postoperative intraocular pressure (IOP) measurements were collected at ~1 month, 3...

“Robot performs cataract surgery on patient!”

Simerdip Kaur takes a look at the latest ophthalmology-related news stories and asks which are scientific reality and which are ‘fake news’. Headline: “Robot performs cataract surgery on patient!” Twenty-five years ago when Eye News launched, a news headline such...

Under pressure: a tool to aid the 
non-ophthalmic practitioner in the timely management of acute angle closure

Acute angle closure is a true ophthalmic emergency that mandates timely diagnosis and treatment. The priority in initial management is to lower the intraocular pressure in an expeditious matter using medical treatments. The risk of irreversible glaucomatous optic neuropathy is...

Complex Biometry Clinics: a new service development

In this article we describe a new local service development, the ‘Complex Biometry Clinic’ at Leicester Royal Infirmary. Retrospective data analysis of patients referred between October 2012 and October 2013 was performed. The aim was to provide a one-stop service...

Biomarkers reveal how patients with glaucoma may respond to treatment

Markers in the blood that predict whether glaucoma patients are at higher risk of continued loss of vision following conventional treatment have been identified by researchers at UCL and Moorfields Eye Hospital.
