Corneal hysteresis: An emerging biomarker in the management of glaucoma

Corneal hysteresis (CH) is gaining recognition as a valuable parameter in the management of glaucoma. Corneal hysteresis is defined as the difference between the inward and outward pressure responses of the cornea during deformation. This measurement reflects the viscoelastic properties...

FAZ measurement on OCTA

This paper aimed to test the AngioVue OCTAs reproducibility and interoperator concordance in evaluating the size of the foveal avascular zone (FAZ). The authors also investigated how the FAZs representation on the OCTA varied after metabolic activity. The right eye...

Does religious fasting affect intraocular pressure or retinal parameters?

Nearly one billion Muslims fast every year during the month of Ramadan. Due to the difference between the lunar and solar calendars, religious fasting time can range from 11 to 17 hours per day. This prolonged abstinence from food and...

Cutting-edge practice in glaucoma care: what, how and why?

More effective treatments and drug delivery modalities, implantable minimally invasive glaucoma surgical (MIGS) devices, as well as accelerating clinical research programmes, will transform the surgical and clinical management of glaucoma in the near future. There is also an ever-greater emphasis...

Passing the Refraction Certificate as a Foundation doctor

Application for ophthalmic specialist training (OST) is competitive. This means you should consider making every effort to maximise your portfolio points, as it may have a significant contribution to your OST application ranking. The “Commitment to Specialty” section is the...

Caring for adults with an ocular tumour

Detection If you screen for an intraocular tumour, dilate the pupil. If the patient is driving, use phenylephrine only. If the patient declines, document this in the casenotes. Don’t forget to look for sentinel vessels, which would indicate a ciliary...

How the development of Glaucoma Guidelines, Glaucoma Toolkit and GLASS training and the Glaucoma nurse training can effect change in Nigeria

In July 2024, a combined training, led by Fatima Kyari, was run in Abuja, Nigeria to facilitate a multifaceted upskilling in glaucoma management. The first week comprised of inviting 36 doctors practising glaucoma from around Nigeria’s 36 states, including the...

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...

Money never sleeps

“I want you to deal with your problems by becoming rich” As declared by Jordan Belfort in a motivational speech to his staff in the film Wolf of Wall Street (2013). Unfortunately, medicine as a career does not lead to...

“Herr Doktor, I can’t see but I am driving”

This 56-year-old lady was quite puzzling. With her own glasses and the pinhole she merely managed to see the 1.3 and 1.0 logMAR lines with her right and left eye, respectively (I am currently working in Germany again, so goodbye...

Comparison of methods of central corneal thickness measurement in glaucoma

This prospective study was done to compare the accuracy and reproducibility of central corneal thickness measured by hand-held and disc-mounted ultrasound pachymeter in glaucoma patients. Sixty-five patients were included in the study. Patients with corneal diseases, corneal astigmatism >3 diopters...

Effect of refractive corneal surgery on IOP and glaucoma progression

Accuracy of intraocular pressure (IOP) measurement depends on the biomechanical properties of the cornea, including its thickness central corneal thickness (CCT) and keratometry (K). Fifty-six eyes of 56 patients with primary open angle glaucoma (POAG) who had a history of...
