Could the sclera be key to glaucoma?

The glaucomas are a group of conditions characterised by optic neuropathy and associated visual field defects. Of these, chronic open-angle glaucoma (COAG) – diagnosed on the basis of progressive structural changes to the optic nerve head (ONH) and nerve fibre...

The role of aspirin in the treatment of NAION: Benefits and controversies

Non-arteritic anterior ischaemic optic neuropathy (NAION) is the most common acute optic neuropathy in individuals over 50 with estimated prevalence of 2–10 per 100,000 people, characterised by sudden, unilateral vision loss due to ischaemic injury to the optic nerve head....

Newer generation IOL platforms designed for high-quality visual performance after cataract surgery

Expanding intraocular lens (IOL) capabilities provide broadening options, ranging from next-generation monofocal IOLs for basic cataract surgery, to specialised premium IOLs for lens-based presbyopia correction and astigmatism correction at the time of cataract surgery. Rod McNeil considers several newer alternative...

Orbital cellulitis - an overview of the diagnosis and management

Enhancing ophthalmology training: Unleashing the power of simulation

Ethical and practical barriers hinder early surgical experience in ophthalmology training [1], which is problematic when early-career trainees bring a higher risk of poor surgical outcomes and patient harm [2]. The European working time directive and the surgical backlog secondary...

Radiation retinopathy

The authors review the current treatment options for this condition. Radiation retinopathy (RR) occurs as a complication after exposure to any type of radiation (external beam, plaque brachytherapy and stereotactic radiosurgery) in the orbital or adnexal region. These include nasopharyngeal...

Simple approach to prevent capsule tear-out during capsulorhexis creation in hyper mature cataracts

Puncturing the anterior capsule in the anterior chamber so that the pressure falls below intracapsular tension causes the rhexis to extend out to the equator. If this develops into a tear that wraps around the entire lens it is called...

Troubleshooting in LASIK

Contemporary laser in situ keratomileusis (LASIK) is safe and effective. It remains the dominant intervention in routine refractive surgery for a good reason: predictable results, rapid visual recovery, and relatively simple strategies for revision treatment. Over 95% of patients are...

A guide to utilising your time efficiently to develop clinical and procedural skills as an aspiring ophthalmologist

Ophthalmology often receives limited coverage in the undergraduate medical curriculum, and the availability of foundation programme jobs in this field is also restricted, reducing exposure to this field for aspiring ophthalmologists. Even if you’re not planning to specialise in ophthalmology,...
