Article Synopsis
- The study analyzed 138 patients with contact lens-related bacterial keratitis (CLBK) over a 7-year period to understand their demographics, CL wear behavior, and treatment outcomes.
- The majority of cases were linked to soft contact lenses, with Pseudomonas aeruginosa and Staphylococcus spp. being the most common bacteria found; poor hygiene was a significant factor in over half the cases.
- Most patients responded well to topical antibiotics, achieving good visual acuity, although older age, female gender, and larger infection size were associated with poorer healing outcomes.
One of the greatest challenges facing the medical community today is the ever-increasing trajectory of antimicrobial resistance (AMR), which is being compounded by the decrease in our antimicrobial armamentarium. From their initial discovery to the current day, antibiotics have seen an exponential increase in their usage, from medical to agricultural use. Benefits aside, this has led to an exponential increase in AMR, with the fear that over 10 million lives are predicted to be lost by 2050, according to the World Health Organisation (WHO).

This was a retrospective study of patients who presented to the Queen's Medical Centre, Nottingham, with suspected BK during 2015-2019. Relevant data, including the demographic factors, risk factors, clinical outcomes, and potential prognostic factors, were analysed.

Methods: This was a retrospective study of patients treated with Ikervis for OSIDs at the Queen's Medical Centre, Nottingham, between 2016 and 2019. Relevant data, including demographics, indications, clinical parameters, outcomes and adverse events, were collected and analysed for patients who had completed at least 6 months follow-up.
Purpose: The purpose of this study is to examine the seasonal patterns of incidence, demographic factors and microbiological profiles of infectious keratitis (IK) in Nottingham, UK.
Methods: A retrospective study of all patients who were diagnosed with IK and underwent corneal scraping during 2008-2019 at a UK tertiary referral centre. Seasonal patterns of incidence (in per 100,000 population-year), demographic factors, culture positivity rate and microbiological profiles of IK were analysed.
Background/aims: To examine the incidence, causative microorganisms and in vitro antimicrobial susceptibility and resistance profiles of infectious keratitis (IK) in Nottingham, UK.
Methods: A retrospective study of all patients who were diagnosed with IK and underwent corneal scraping between July 2007 and October 2019 (a 12-year period) at a UK tertiary referral centre. Relevant data, including demographic factors, microbiological profiles and in vitro antibiotic susceptibility of IK, were analysed.

Best's macular dystrophy (BMD) usually manifests with visual failure in the first or second decade of life; however, there is a large variability in expressivity of the disease, and some patients have no manifestation other than a pathological electro-oculogram (EOG). Autosomal dominant Best's vitelliform macular dystrophy (AD-BVMD) has a very specific phenotype that varies with the stage of the disease. In recent years, the authors have seen description of another clinical entity known as autosomal recessive BMD.

Methods A retrospective analysis of 70 consecutive cases of DSEK. All donor lenticules were dissected manually.

Methods: The charts of patients fit with SynergEyes lenses during the first 7 months the lens was available on the Cornea Service at Wills Eye Institute (August 3, 2006 to March 5, 2007) were retrospectively reviewed.
Results: Sixty-one eyes (44 patients) with KC (58 eyes) or PMD (3 eyes) were fit with SynergEyes hybrid contacts.
