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...

Intraocular lens technology to deliver enhanced optical performance after cataract refractive surgery

Modern cataract surgery aims to provide patients with the best possible visual outcome with the least dependence on spectacles and minimal or no complications and to treat both cataract and refractive errors with a single procedure. Phacoemulsification is the standard...

Understanding and confronting bacterial endophthalmitis

Abdus Samad Ansari highlights the importance of early recognition of this condition using an unusual presentation. Endophthalmitis is a medical emergency with devastating consequences. Despite adequate treatment, severe cases frequently result in permanent blindness. Endophthalmitis involves inflammation of both the...

Rb-NET: a network to save life and preserve vision in children in Africa

Responding to need is a key element underpinning the VISION 2020 LINKS Programme [1]. It is embedded in the process through which LINKS are established, with institutions in low- and middle-income countries (LMICs) first defining their priority areas of training...

Globes in space: What would happen to our globes on the globe of Mars?

Many films have been made regarding life on alternative planets. With the Mars One mission approaching in 2023, there are high expectations regarding future interplanetary travel. The authors provide an ophthalmology perspective on what could happen to our eyes if...

My Top Five: Red flag presentations all resident doctors must know

Ophthalmic emergencies are time-critical situations where delays in recognition or management can lead to permanent vision loss [1]. For resident doctors and medical students, identifying these red flags can be daunting, especially given the complexity of the eye and its...
