Active clinical trials for "Keratoconjunctivitis"

Every night during sleep, there is an accumulation of white blood cells in the closed eye. The closed eye white blood cells are predominantly neutrophils, but there is a small population (3%) of T cells. The effects of these closed eye white blood cells on dry eye disease pathogenesis have yet to be fully elucidated, but preliminary evidence suggests that closed eye neutrophils may have an associated hyperactivity and increased degranulation in dry eye disease that could contribute to epithelial instability. As an anti-T cell therapy, Xiidra offers an opportunity to better understand how the closed eye white blood cells are recruited and activated. This study also seeks to verify the proposed mechanism of action.

To investigate and compare the burden of dry eye in Sjögren's syndrome dry eye vs non-Sjögren's syndrome dry eye, as well as investigate the diagnostic potential of tear film mucins and various inflammatory cytokines evaluated by tear fluid analysis and impression cytology.

The purpose of this study is to evaluate the effect of the controlled adverse environment (CAE) on Mean Break-Up Area in subjects diagnosed with Dry Eye Syndrome.

This study will evaluate the efficacy of cyclosporine ophthalmic solution vs. other non-prescription treatments in patients with dry eye disease. Patient and physician assessments completed at baseline, at each follow-up visit (follow-up visits are variable as per physician discretion) and at final follow-up visit.

VKC is more common in males and tends to resolve with pubertal development. Clinical observation was not followed by an investigation that clarified whether there is a correlation between the hormonal pattern and the evolution of the disease, in particular it is not defined whether there is a correlation between the hormonal pattern and the resolution of the disease. This study aims to evaluate the hormonal pattern in patients with VKC and, in particular, the possible role of these hormones in the resolution of this condition in puberty.

The purpose of this study is to compare acute tear production produced by the Oculeve Intranasal Lacrimal Neurostimulator with two control devices in participants with aqueous tear deficiency.

The primary objective of this study is to evaluate acute tear production as measured by tear meniscus height (TMH) captured by optical coherence tomography (OCT) after single use of the Oculeve Intranasal Neurostimulator (OIN) in participants with dry eye.

Non-interventional single-center cohort study (Rothschild Foundation Hospital) of patients aged 0 to 18 years followed up in ophthalmology for KCV, treated with tacrolimus 0.1% eye drops previously treated with ciclosporin 2% with treatment failure. Prospective collection of quality of life from the parents and/or, if possible, the children via the QUICK questionnaire and 6 additional questions Retrospective collection of clinical data (secondary endpoints) from the patients' medical records, aiming to compare the period before the start of treatment and the period under treatment with TALYMUS The objective of this study is to evaluate the response to TALYMUS® treatment in patients with Vernal keratoconjunctivitis who have failed ciclosporin 2% therapy, whether due to lack of efficacy, compliance difficulties or poor tolerance.

This study will be used to support assessment of AIR OPTIX® NIGHT & DAY® AQUA (AONDA) Soft Contact Lenses' safety and performance in accordance with updated European Union Medical Device Regulation (EU MDR) requirements.

This is a prospective, observational case series to determine the clinical utility of tear osmolarity and other commonly used objective tests to diagnose dry eye disease, as well as to establish referent values for objective tests of the disease.
