CFEH Rapid Research Review: Recent Episodes
Centre for Eye Health
The Rapid Research Review podcast is a resource for clinical optometrists. These short 5-minute updates spotlight recent research articles that have clinical impact. In each episode, we pose a clinically relevant question and by the end, should offer new ideas that can be implemented in the consulting room.
OCT Angiography is a valuable, non-invasive method for obtaining information about blood flow. Blood flow is relevant to glaucoma, but how do we integrate the information gained from OCTA into our clinical glaucoma practice? In this episode Dr Jack Phu discusses the work of Kamalipour and colleagues from the Shiley Eye Institute, UC San Diego, and asks the question "Does OCTA predict future visual field progression?"

In this episode, host Dr Jack Phu talks with CFEH Optometrist Henrietta Wang about her recent research investigating whether these is a connection between latanoprost and migraine headaches. They will discuss some really interesting findings from this study which will be valuable to those optometrists involved in treating glaucoma.

In this episode, Dr Phu reviews some reserach by Shah and colleagues that surveyed patients with diagnosed or suspected glaucoma to identify their visual symptoms, then correlated these to the visual field loss in their worse eye. This paper helps us, as clinicians, to understand the most common symptoms reported by patients with glaucoma. It also investigates how the frequency of symptoms experienced changes as the severity of these symptoms increase.

In this episode we review a paper by Lam et al. that examines both the advantages and challenges associated with telemedicine in glaucoma care. It may even be an area for future development within your practice!

In this episode Dr Phu examines a recent publication by Muthusamy et al. which presents their research into patient perceptions around visual field testing. Are these patients happy to do more than one visual field test in a visit if it adds further clinical information? Are they happy to return more often for visual field testing if this adds to the clinical picture? Are there modifiable factors that can make field testing more comfortable for your patient?

In this episode, your host Dr Jack Phu discusses the link between myopia and glaucoma in the context of a recent meta analysis by Ahnul Ha et al. This work has significant clinical implications for optometrists managing patients with high or very high myopia.

In this episode your host Dr Jack Phu discusses a paper by Xiaoxiao Ma et al. that evaluates and compares the identification of visual field defect using both kinetic and static perimetry. Given the large diversity of possible glaucomatous defects, can testing in glaucoma be limited to just static perimetry?

In this episode, Dr Jack Phu introduces the concept of frontloading visual fields (doing two visual field tests per eye in one clinical visit), and discusses the implications on field reliability and repeatability with this approach. This may change the way you conduct visual field testing in your practice!

Presented by Dr Jack Phu, this inaugural episode of Rapid Research Review discusses a paper by McGarva et al. (2021) that analyses feasibility and clinical usefulness of self-tonometry in the home setting.
