Background: Eye banks have procured, processed and stored donor corneas for decades. In parallel, new techniques have emerged employing allogeneic transplantation of various cells and tissues from the eye banks. This progress is a consequence of increased knowledge of stem cells, cell kinetics and immunological aspects and improved techniques for cell culturing, tissue storage and microsurgery.
Material And Methods: Review article on available transplants for treating eye diseases, based on experience with eye banking, clinical ophthalmological practice, own research and literature retrieved from PubMed, Medline and www.google.com.
Results And Interpretation: Treatment techniques for eye diseases, which require biological material for grafting, need efficient eye banks for continuous supply of donor material of high quality. New Norwegian legislation, based on implementation of EU Directive 2004/23/EC, demands authorization of all eye banks. The EU Directive sets high and rigorous standards for quality and safety for donation, procurement, testing, processing, storage and distribution of tissues and cells. Well-run eye banks are of great importance for modern treatment of patients suffering from eye diseases and for progress and research in ophthalmology.

Background/aims: To examine the association between sociodemographic characteristics and attendance at Hospital Eye Service (HES) referrals from the Diabetic Eye Screening Programme (DESP), in a large, ethnically diverse urban population.
Methods: Retrospective cohort study (4 January 2016-12 August 2019) of people with diabetic retinopathy (DR) referred from an English DESP to a tertiary referral eye hospital. We conducted a multivariable logistic regression with attendance as the primary outcome, controlling for age, sex, ethnicity, Index of Multiple Deprivation, best eye visual acuity and baseline DR grade.

Background: To describe a case of guttae recurrence in bilateral corneal grafts in a patient with a known diagnosis of Fuchs endothelial dystrophy, more than three decades following penetrating keratoplasty.
Methods: Case Report.
Results: A 79-year-old White woman presented with declining vision, right eye worse than the left.

Purpose: The purpose of this study was to identify serum metabolites associated with age-related macular degeneration (AMD) incidence and investigate whether metabolite profiles enhance AMD risk prediction.
Methods: In a prospective cohort study involving 240,317 UK Biobank participants, we assessed the associations of 168 metabolites with AMD incidence using Cox hazards models. Principal component analysis (PCA) captured 90% of the variance in metabolites.

The cornea, the anterior meniscus-shaped transparent and refractive structure of the eyeball, is the first mechanical barrier of the eye. Its functionality heavily relies on the health of its endothelium, its most posterior layer. The treatment of corneal endothelial cells (CECs) deficiency is allogeneic corneal graft using stored donor corneas.
