Pathologic myopia is the seventh leading cause of blindness in the US and two percent of Americans have the disease; Canadian statistics are not available. Pathologic myopia involves elongation of the eyeball and scleral support surgery aims to control the progression of this elongation. The most commonly used technique involves placing a strip of sclera from a donor eye around the eyeball to prevent further stretching. Due to variable trial designs and variable patient characteristics, this review determined there is insufficient evidence to establish the clinical efficacy of this procedure. More robust evidence is required, using standardized techniques and standardized outcome measures, before a meaningful evaluation of scleral support surgery can be conducted.

Experimental Evaluation of Ocular Rigidity and Pressure-Volume Relationship After Ex-Vivo Scleral Cross-Linking With Riboflavin and Ultraviolet A in Porcine Eyes.
Cureus
December 2024
Ophthalmology, Medical School, Institute of Vision and Optics, University of Crete, Heraklion, GRC.
Purpose: Scleral cross-linking (SXL) with ultraviolet A (UVA) and riboflavin has already been used in laboratory studies for scleral stiffness increase as a potential treatment for progressive myopia and scleral ectasia. This study aims to investigate whether the regional application of scleral cross-linking (SXL) with ultraviolet A (UVA) and riboflavin in fresh porcine eye globes affects the ocular rigidity as well as its impact on intraocular pressure after an induced acute increase in the volume of intraocular fluid.
Methods: The study included two groups of fresh porcine eyes: an experimental group (n=20) that underwent scleral cross-linking (SXL) with riboflavin and UVA applied to the posterior sclera and a control group (n=20) that did not receive SXL treatment.
Quarter of a century of contact lens prescribing trends in Australia (2000-2024).
Clin Exp Optom
January 2025
Eurolens Research, Division of Pharmacy and Optometry, The University of Manchester, Manchester, UK.
Clinical Relevance: Knowledge of contact lens prescribing trends can (a) assist practitioners to benchmark their own prescribing habits, (b) help the contact lens industry understand preferred products, and (c) support academics in scholarly writings.
Background: This work aims to document contact lens prescribing trends in Australia over the past quarter of a century.
Methods: An annual survey of contact lens prescribing trends was conducted in Australia each year from 2000 to 2024, inclusive, by asking optometrists to provide information relating to 10 consecutive contact lens fits undertaken between January and March.
Long-Term Effectiveness of Scleral Lens Treatment in the Management of Keratoconus: A Systematic Review.
Cureus
January 2025
Trauma and Orthopaedics, Oxford University Hospitals NHS Foundation Trust, Oxford, GBR.
This systematic review evaluates the long-term effectiveness of scleral lenses in improving visual outcomes, patient satisfaction, and safety in patients with keratoconus. A systematic search of six databases (PubMed, Embase, Web of Science, Scopus, Cochrane Library, and MEDLINE) was performed following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The inclusion criteria included studies with more than or equal to three months of follow-up, included a minimum of 20 keratoconus patients, published after year 2020 and outcomes reporting visual acuity, comfort or quality of life.

Ocular microtremor (OMT) is a fixational eye movement that cannot be seen with the naked eye but is always present, even when the eye appears motionless/still. The link between OMT and brain function provides a strong rationale for investigation as there lies potential for its use as a biomarker in populations with neurological impairments. OMT frequency is typically 70-80Hz in healthy adults and research suggests that this will be reduced in those with neurological disease such as Parkinson's Disease (PD).

During the COVID-19 pandemic, reducing aerosol-generating procedures became fundamental, particularly in ophthalmic surgeries traditionally performed under general anesthesia (GA). Regional anesthesia, such as sub-Tenon's block (STB), is widely used in vitreoretinal surgeries, offering a safer alternative by avoiding airway manipulation. However, the altered orbital anatomy in patients with previous scleral explant surgery creates unique challenges to STB application.
