Purpose: The purpose of this study was to characterize the morphological and immunological aspects of biointegration at the optic-cornea joint of a second-generation synthetic corneal device.

Methods: The initial prototype, single-piece optic-skirt configuration, is constructed from compact and flexible perfluoroalkoxy alkane with porous expanded polytetrafluoroethylene (ePTFE) overlying the skirt to allow skirt-cornea biointegration. The second-generation version was modified to add ePTFE around the optic wall to allow optic-cornea biointegration.

Background: Sjögren's disease is a chronic autoimmune disease with an unmet need for targeted therapies. The aim of the TWINSS study is to evaluate the safety and efficacy of iscalimab, a monoclonal antibody against CD40, in patients with active Sjögren's disease.

Methods: This randomised, double-blind, placebo-controlled, phase 2b study, conducted at 71 sites in 23 countries, enrolled patients aged 18 years or older fulfilling the American College of Rheumatology/European Alliance of Associations for Rheumatology (EULAR) 2016 criteria.

Purpose Of Review: Cyclosporine is a versatile immunomodulatory drug commonly employed in modern medicine. Although cyclosporine was initially used to prevent solid organ transplant rejection, its indications have extended to treat many inflammatory or autoimmune diseases. Cyclosporin is available for use in oral, intravenous, and topical forms, including eye drops to treat corneal and ocular surface conditions.

Purpose: We sought to introduce the materials, design, and biocompatibility of a flexible and suturable artificial corneal device.

Methods: Single-piece, fully synthetic, optic-skirt design devices were made from compact perfluoroalkoxy alkane. The skirt and the optic wall surfaces were lined with a porous tissue ingrowth material using expanded polytetrafluoroethylene.

Purpose: To evaluate a commercially available dexamethasone intracanalicular insert to treat dry eye.

Design: Single-center, double-masked randomized controlled trial.

Participants: Patients with clinically significant aqueous-deficient dry eye (combined ocular surface staining score, ≥ 3 [0-12]; corneal fluorescein staining score, ≥ 2 [0-6]; and Schirmer's wetting, < 10 mm at 5 minutes in both eyes) with symptoms (dryness, eye discomfort, or visual fatigue, ≥ 30 [0-100]) despite treatment with at least 1 prescription drop and deemed candidates for topical steroid therapy.

Purpose: The purpose of this study was to investigate the impact of demographic characteristics and psychiatric comorbidity on the prevalence of dry eye disease in the American geriatric population.

Methods: Data were collected from a 2011 nationwide sample of Medicare beneficiaries aged 65 years and older (N = 1,321,000). Age, sex, race/ethnicity, residential area, climate region, and income, along with psychiatric comorbidities including depression and anxiety, were collected.

Article Synopsis
  • Sjögren's disease (SjD) is a complex autoimmune condition characterized by symptoms like dryness, pain, and fatigue, affecting various organ systems in different ways.
  • The variability in symptoms among patients complicates the development of effective treatments, highlighting the need to better understand the disease.
  • In 2023, the OMERACT SjD Working Group held a hybrid meeting to review research and establish core disease domains that reflect both clinical features and patient experiences, ultimately producing a provisional domain list to address SjD's diversity.

Background: The diagnosis of dry eye and other common ophthalmological conditions can be supported using patient reported symptoms, which is increasingly useful in contexts such as telemedicine. We aim to ascertain visual symptoms that differentiate dry eye from cataract, glaucoma, or glaucoma suspects.

Methods: Adults with dry eye, glaucoma, cataract, and suspected glaucoma (controls) completed a questionnaire to rate the frequency and severity of 28 visual symptoms.

Article Synopsis
  • The study investigates ocular signs and symptoms in participants from the Sjögren's International Collaborative Clinical Alliance cohort, comparing those with and without Sjögren's disease (SjD).
  • Out of 3,380 participants, it was found that while ocular symptoms were similar between SjD and non-SjD groups, SjD participants had significantly higher ocular staining scores and were more likely to show specific ocular abnormalities.
  • The findings suggest that SjD correlates with increased ocular pathology, and particular corneal staining patterns may serve as useful biomarkers for SjD-related dryness.

Dry eye is an increasingly common ocular condition with significant impact on quality of life due to eye discomfort and blurred vision complaints. In addition, the financial burden of dry eye on both patients and society is substantial. Although there has been a recent explosion of research in the field since 2002 with the approval of the first prescription topical treatment (Restasis, Allergan Inc, Irvine CA), dry eye lags behind other ophthalmic conditions where clinically meaningful outcome measures are closely tied with the metrics by which their therapeutics are evaluated.

Purpose: This study aimed to review the demographics, clinical characteristics, and long-term outcomes of therapeutic penetrating keratoplasty (TPK) performed in a tertiary eye care hospital.

Methods: Case records of 149 therapeutic transplants (135 patients) that were performed during the calendar year 2016 were retrospectively analyzed, and outcomes were measured until 3 years of follow-up. Information on demographics, presentation characteristics, keratoplasty indications, offending microbe, and secondary surgical interventions was studied.
