Reproducibility and within-subject variability of HRK-9000A meibography in normal young participants
Gantz L, Wilks J and Ifrah R
Reliable assessment is critical for diagnosing and managing meibomian gland dysfunction. Multi-functional diagnostic devices, such as meibographers, streamline clinical workflows by integrating multiple ocular assessments. Ensuring reproducibility across examiners is vital for accurate diagnosis and monitoring of treatment. This prospective study determined the inter-examiner reproducibility (IER), inter-rater reproducibility (IRR) and within-subject variability (WSV) of the Huvitz HRK-9000A meibographer.
Scleral lens wear and fluid reservoir turbidity in eyes with ocular surface disorders
Goppalakrishnan VA, Srinivasan B, Iyer G and Iqbal A
To investigate changes in fluid reservoir turbidity parameters over time and its influence on visual performance in eyes with ocular surface disorders (OSD) wearing scleral contact lenses (SL).
Impact of orthokeratology and low-dose atropine on corneal biomechanics and myopia progression in children
Lee SH, Tsai PC, Chiu YC, Wang JH and Chiu CJ
This study evaluated the effects of orthokeratology and 0.01% atropine on corneal biomechanical properties (CBPs) and myopia progression in children, focusing on their association with axial length (AL) changes and treatment outcomes.
The diagnostic accuracy and feasibility of paediatric visual field tests: A systematic review
Riaz M, Ross NC and Mayer DL
Alternative non-standard paediatric visual field (VF) tests have been developed to address the challenges associated with standard approaches. However, diagnostic accuracy of these new VF tests has not yet been rigorously evaluated. This systematic review aims to explore diagnostic accuracy and feasibility of non-standard VF tests in paediatric patients.
The repeatability of macular and peripapillary vessel density in participants with different severities of glaucoma
Hsia Y, Wang TH, Huang JY and Su CC
To investigate the repeatability of optical coherence tomography angiography (OCTA) parameters in participants with different severities of glaucoma.
Quantifying tear exchange during rigid contact lens wear using corneoscleral profilometry: A proof of concept study
Iqbal A, Fisher D, Alonso-Caneiro D, Collins MJ and Vincent SJ
Tear exchange during contact lens wear is essential for ocular surface integrity, facilitating debris removal, and maintaining corneal metabolism. Fluorophotometry and fluorogram methods are typically used to measure tear exchange, which require hardware modifications to a slit lamp biomicroscope. This manuscript introduces an alternative method using a corneoscleral profilometer, the Eye Surface Profiler (ESP), to quantify tear exchange during corneal and scleral rigid lens wear by assessing fluorescence intensity changes over time.
Repeatability of lipid layer thickness using LipiView® following removal of contact lenses and its relationship to comfort
Kumar M, Masoudi S, Vijay AK, Naduvilath TJ, Dumpati S, Raj A and Willcox M
To assess the repeatability of lipid layer thickness (LLT) measurement using the LipiView® interferometer after daily disposable contact lens (CL) wear and correlation with ocular comfort in soft contact lens wearers.

Evaluation of the perception of information from ChatGPT in myopia education: Perspectives of students and professionals
Sanchez Tena MA, Alvarez-Peregrina C and Martinez-Perez C
The purpose of this study was to compare the perception and understanding of the information provided by ChatGPT regarding myopia among optometry students, optometrists undertaking a Master degree and practicing optometrists.
'Such a lot of bother': Qualitative results of a home trial of a wearable electronic vision enhancement system for people with age-related macular degeneration
Miller A, Macnaughton J, Crossland MD and Latham K
Wearable electronic low vision enhancement systems (wEVES) improve visual function but are not widely adopted by people with vision impairment. Here, qualitative research methods were used to investigate the usefulness of wEVES for people with age-related macular degeneration (AMD) after an extended home trial.
Longitudinal measures of peripheral optical quality in young children
Vera-Diaz FA, Dhungel D, McCullough A, Kerber KL and Bex PJ
To assess longitudinal changes in optical quality across the periphery (horizontal meridian, 60°) in young children who are at high (HR) or low risk (LR) of developing myopia, as well as a small subgroup of children who developed myopia over a 3-year time frame.
Can fundus features tell us something about 3D eye shape?
Yii F, Strang NC, Gibbon S and MacGillivray TJ
To determine whether imaging features derived from fundus photographs contain 3D eye shape information beyond that available from spherical equivalent refraction (SER).

Prevalence of interocular symmetry in corneal astigmatism and the possible influence of age, sex and refractive error
Salvador-Roger R, Micó V and Esteve-Taboada JJ
The aim of this study was to investigate, using a power vector approach, whether corneal astigmatism follows a mirror symmetry pattern considering both the magnitude and axis, and whether age, sex and spherical equivalent refractive error can influence the pattern.
The Maddox rod: Revisiting the optics
Habib M and Andrew NH
The Maddox rod is a staple in the assessment of strabismus. However, its optics mechanism is puzzling. How is it that an orthogonal line focus is formed? Surprisingly, few texts offer an explanation and those that do either provide insufficient detail, contain misleading information or are difficult to follow. There is a prevalent misconception that multiple cylinders are required for the orthogonal line focus to appear. However, this is untrue; Maddox himself only used a single cylinder when he first described the phenomenon. Herein, we review the optics explanations provided in a sample of texts and offer an accurate explanation using the biplanar principle of astigmatic refraction.

Photoreceptor layer elevation due to subretinal fluid: Impact on visual acuity measurements and simulation from biometrics
Parimi V, Elsner AE, Papay JA, Clark CA, Miura M and Gast TJ
Visual acuity (VA) is a primary outcome measure that defines the success of clinical interventions for retinal diseases such as age-related macular degeneration (AMD) or diabetic macular oedema (DME). These conditions can lead to the presence of subretinal fluid, causing substantial photoreceptor layer elevation. Hyperopic defocus then occurs, affecting the VA measurements. In this study, we simulated the induced hyperopic shift for real-world values of photoreceptor layer elevation and measured the effect on VA measurements.
