Large language models in ophthalmology

Traditional artificial intelligence (AI) models typically require large amounts of labelled data for training. For example, to develop a model capable of detecting macular pathologies on optical coherence tomography scans, thousands of scans would need to be manually labelled by...

Histopathological changes in rabbit retinitis pigmentosa

The authors report the histopathological changes of retinal ganglion cells (RGCs), optic disc and optic nerve in rabbit with advanced retinitis pigmentosa (RP). RP was recreated in rabbits by using bacterial artificial chromosome transgenesis, with the purpose of increasing understanding...

Endothelial cell loss using different graft injectors in DMEK

This study aimed to investigate endothelial cell loss between two injector systems in descemet membrane endothelial keratoplasty (DMEK) grafts; a glass injector – modified Jones tube and a plastic injector – closed system IOL injector, the Viscoject 2.2 system. DMEK...

Treatment of Sjogren’s Syndrome dry eye in mouse model

Sjogren’s syndrome (SS) is a chronic autoimmune disease characterised by inflammation of the exocrine glands, specifically the salivary and lacrimal glands that produce saliva and tears, respectively. The immune-mediated attack on the salivary and lacrimal glands leads to the development...

The impact of conjunctivochalasis on dry eye symptoms and signs

The study aimed to draw a relationship between conjunctivochalasis and dry eye symptoms via a dry eye questionnaire (DEQ5), as well as signs such as tear osmolarity, tear break up time, corneal staining, Schirmer score, meibomian gland dropout, eye lid...

IgG4 related orbital disease

This retrospective study was done to determine the prevalence of IgG4 related orbital disease (IgG4ROD) in patients who previously had biopsies for suspected idiopathic orbital inflammatory disease (IOID) and / or orbital lymphoproliferative disease (OLD). The charts and slides of...

Meibomian gland dropout in patients with dry eyes

In this prospective study 264 patients with symptoms of dry eye were examined with a non-contact meibography system to assess the morphological changes in their meibomian glands. These patients were not previously diagnosed with meibomian gland dysfunction and patients with...

Cataract in patients with pseudoexfoliation syndrome

The authors present a prospective comparative study in 43 patients with (group 1) or without (group 2) pseudoexfoliation (PXF) undergoing cataract surgery. Anterior capsule samples were obtained in all patients and analysed for signs of apoptosis by using special staining...

Pterygium ocular surface temperature

This prospective study investigated the ocular surface temperature in patients with pterygia compared to those with dry and healthy eyes respectively. Previous studies have shown that patients with dry eyes show a significant decrease in ocular surface temperature on sustained...

Liquid adhesive bandage for clear corneal cataract incisions

This paper reports a prospective randomised controlled trial of patients undergoing routine phacoemulsification with a 2.75mm clear corneal incision and followed up for 14 days postoperatively. They evaluated wound edge closure, surgically induced astigmatism and foreign body sensation after use...

Tear production levels and dry eye disease

Dry eye disease (DED) is multifactorial, caused by an alteration in the quality or quantity of tear film’s three layers. Several tests are available for diagnosis. The aim of this study was to determine if the Schirmer test (ST) could...

Comparison of bleb grading and IOPs

The purpose of this study was to compare a novel anterior segment optical coherence tomography (AS-OCT) bleb grading system with a clinical bleb grading system (Moorfields) and both with intraocular pressure (IOP) levels following trabeculectomy surgery. The authors developed a...
