Does the length of the school day have a role in age of myopia onset?

The authors prospectively collected the refractive data of myopic adults attending recruiting dispensing optician or ophthalmologist sites. Participants were recruited consecutively, giving verbal informed consent. Sites included a mix of urban and rural areas across eight sites. The following data...

OCTA in diabetic macular oedema treated with intravitreal aflibercept (DOCTA Study)

Central vision loss due to diabetic macular oedema (DME) can be attributed not only to presence of the macular oedema itself but also, in some cases, to alterations of the foveal avascular zone (FAZ). The DOCTA trial was a longitudinal,...

An unusual case of sellar chondroma

A single case of chondrogenic neoplasm arising from the base of the skull is presented and discussed. These benign and slow growing tumours in the sellar region are extremely rare and as such this article provides a useful insight and...

Ultrasound imaging of the eyes

Since its initial use in the eyes fifty years ago, ultrasound has established itself as a common diagnostic technique in ophthalmology. Sonographers, engineers and clinicians from all around the world have contributed to the development of ocular ultrasonography. As a...

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...

Practical phacodynamics – making the most of your phacoemulsification machine

Understanding phacodynamics is appreciating the subtleties in the dynamic changes of the fluidics and the ultrasonic power delivered. Kristina Southcott explains. Increase my vacuum! Increase my bottle height! Increase my phaco power! I frequently observe the above commands being directed...

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....

Internuclear ophthalmoplegia: a case study

A 44-year-old patient presents with binocular, mostly horizontal diplopia when fixating on moving objects. This has been ongoing for approximately five years. He is known to have multiple sclerosis and had an episode of optic neuritis six years prior in...

Beyond the slit lamp: Unanticipated lessons from my ophthalmology elective

My six-week elective in ophthalmology at Westmead Hospital in Sydney offered much more than technical mastery; it challenged my assumptions about patient care, teaching and the role of curiosity in medicine. Though my passion for eyes was ignited by my...

Landmark dataset to accelerate research on anterior segment eye disease

Diseases affecting the anterior segment, the front part of the eye, are among the leading causes of visual impairment and blindness globally, yet few large-scale datasets have been available for these conditions. In response, clinical researchers at Moorfields Eye Hospital...

Ocular manifestations of multiple sclerosis: an overview

Multiple sclerosis (MS) is an autoimmune demyelinating disease of the central nervous system (CNS), in which there is dissemination of lesions in time (two or more clinical events) and space (multiple lesions seen on brain and spinal imaging). The pathophysiology...

Artificial intelligence in eyecare: how do we ensure new technologies truly benefit our patients?

From monitoring patients with heart disease to improving the early diagnosis of cancer, artificial intelligence (AI) using deep learning techniques is already employed in many different healthcare specialties [1]. In the eyecare field, AI technologies have been used to analyse...
