Background: To identify evidence on the use of topical CsA for ocular surface diseases (OSD).

Methods: A literature search was conducted following the preferred reporting items for systematic reviews and meta-analyses (PRISMA) through June 2023 via Cochrane Central Registries, Clinical Trials Registry, Grey literature and citation searching. Randomised clinical trials (RCTs) in which different concentrations of topical CsA were compared with one another or other topical therapies were included.

Purpose: We report a unique case of significant human papillomavirus-associated conjunctival papillomas and severe corneal ulceration leading to corneal perforation in a patient treated with dupilumab for atopic dermatitis.

Methods: This study is a case report and literature review of severe corneal side effects related to dupilumab.

Results: A 27-year-old man with severe atopic dermatitis and no ocular history was administered dupilumab 300 mg via subcutaneous injections every 2 weeks with an excellent response.

Purpose: This study evaluates the performance of a multitrait polygenic risk score (PRS) in an independent cohort to predict incident or progression of keratoconus.

Design: Prospective cross-sectional and cohort study METHODS: Setting: Single-center; Study population: 1478 community-based young adults (18-30 years; 51% female), including 609 (52% female) who returned for an 8-year follow-up; Observation procedures: Scheimpflug imaging (Pentacam, Oculus), genotyping and development of a multitrait PRS previously validated to predict keratoconus in older adults.; Main outcome measure: Belin/Ambrόsio enhanced ectasia display (BAD-D) score and keratoconus, defined as BAD-D ≥2.

Background: Chronic spontaneous urticaria (CSU) is an immunologic condition with an estimated prevalence of 0.1%. For CSU that is poorly controlled despite the use of antihistamines, omalizumab is the only treatment approved and recommended by international guidelines.

Background: To compare graft survival of endothelial keratoplasty (EK) versus penetrating keratoplasty (PK) in patients with iridocorneal endothelial (ICE) syndrome and identify ocular features associated with graft survival.

Methods: Observational, prospective, cohort study. A total of 30 806 first grafts performed between 1985 and 2020 were identified through the Australian Corneal Graft Registry and included in this observational, prospective cohort study.

Clinical Relevance: The Keratoconus International Consortium (KIC) will allow better understanding of keratoconus.

Background: Keratoconus is a disorder characterised by corneal elevation and thinning, leading to reduced vision. The current gaps in understanding of this disease will be discussed and the need for a multi-pronged and multi-centre engagement to enhance our understanding of keratoconus will be highlighted.

Unlabelled: The Drug Hypersensitivity Quality of Life Questionnaire (DrHy-Q) is not currently available in Chinese. Besides, penicillin allergy (PA) is a worldwide public health challenge, and delabeling inauthentic PA can improve clinical and economic outcomes. However, its effect on health-related quality of life (HRQoL) remains poorly known.

This review discusses the current practices, attitudes, and trends in diagnosing and managing keratoconus (KC) in adults and children by optometrists and ophthalmologists in order to highlight the differences on a global scale. Two independent reviewers searched the electronic databases and grey literature for all potential articles published from 1 January 2000 to 1 June 2022 on management of KC. Keywords used in searches included "keratoconus", "diagnosis", "management", "treatment", "attitude", "practices", "opinion", "optometrist", "ophthalmologist", "consensus", and "protocol".

Previous studies have suggested risk factors for graft dislocation after Descemet stripping automated endothelial keratoplasty (DSAEK). We aimed to investigate the influence of eye bank storage solution as a risk factor for graft dislocation, as this could have significant implications for eye banking practices. This retrospective analysis compared cohorts from the QEII Health Sciences Center, Halifax, Canada (donor corneas preserved in Optisol GS) and the Royal Victorian Eye and Ear Hospital, Melbourne, Australia (donor corneas preserved in organ culture).

Purpose: Descemet´s membrane ruptures (with a discontinuation of Descemet´s membrane and double detached coiled edges) in the context of complicated anterior segment surgery have rarely been described and its management can be challenging. We report a modified Descemet stripping only (DSO) technique associated with ripasudil drops to treat these cases when other techniques fail.

Methods: We describe two cases of large Descemet´s membrane detachments associated with Descemet´s ruptures after cataract surgery that did not respond to two SF intracameral injections.

Purpose: To investigate the performance of a machine learning model based on a reduced dimensionality parameter space derived from complete Pentacam parameters to identify subclinical keratoconus (KC).

Methods: All 1692 available parameters were obtained from the Pentacam imaging machine on 145 subclinical KC and 122 control eyes. We applied a principal component analysis (PCA) to the complete Pentacam dataset to reduce its parameter dimensionality.

Article Synopsis
  • * A large-scale study involving nearly 4,700 keratoconus cases and over 116,000 controls identified 36 genomic regions linked to the disease, highlighting issues with collagen integrity and cell differentiation as crucial factors.
  • * The findings reveal shared genetic mechanisms with other corneal diseases and suggest that the identified genetic variants account for 12.5% of keratoconus's genetic risk, paving the way for future diagnostic tests to assess susceptibility.

Purpose: To report the long-term outcomes after phototherapeutic keratectomy (PTK) for the treatment of bullous keratopathy.

Methods: This is a retrospective medical record review of all patients with symptomatic bullous keratopathy who underwent PTK between June 2005 and March 2019 at the Royal Victorian Eye and Ear Hospital who were followed up for at least 12 months after the procedure. Medical records were used to extract demographic data, etiology of bullous keratopathy, complication rates, and subsequent procedures after PTK.

Purpose: Keratoconus is a potentially blinding condition that slowly deforms the cornea in young people. Despite the increasing prevalence of keratoconus, the exact aetiology of the condition is unknown. This first systematic review examines the evidence of eye rubbing and its association with keratoconus and presents the findings of the meta-analysis.

Ocular rosacea is a chronic inflammatory condition that can occur in the absence of cutaneous features. The most common ocular features are chronic blepharoconjunctivitis with eyelid margin inflammation and meibomian gland dysfunction. Corneal complications include corneal vascularization, ulceration, scarring and, rarely, perforation.

Significance: Our results show that asthmatic patients tend to have more severe KC and thus close monitoring for disease progression would be advised, and appropriate treatment strategies may be actioned stabilise the condition that may reduce the need for future corneal transplantation.

Purpose: To explore a wide range of risk factors associated with the severity of keratoconus (KC).

Methods: A cross-sectional study of KC patients was undertaken in Melbourne, Australia.
