Active clinical trials for "Conjunctivitis"

This study will be used to evaluate how patients put eye drops in their eyes and any problems that may arise from this activity. The information gathered will help identify common problems patients are having with putting in their eye medications. Then doctors can be better informed about the issues and provide better advice to their patients to overcome these problems.

This study will gather information on allergic rhinoconjunctivitis from surveys completed by adults and children.

All participants will underwent imaging using the OCTA system (Zeiss) with the anterior segment optical adaptor lens. The main outcomes are iris blood flow density and vascular density.

Background and purpose: Allergic conjunctivitis has increased alarmingly in recent years. The objectives of the study are: 1) To establish the safety and efficacy of applying eyewashes in spray form as monotherapy on the symptoms and signs of allergic conjunctivitis; 2) To establish the comparative efficacy with other eye drops as antihistamines; 3) To measure the modification of immunoglobulin E (IgE) and matrix metalloproteinase 9 (MMP9) levels in the tears.

This study aims to assess the cytokine profile of tears in patients suffering from conjunctivitis versus patients without ocular involvement, when treated with Dupilumab

By measuring and comparing the corneal biomechanical parameters of normal people, patients with allergic conjunctivitis, keratoconus, whether allergic conjunctivitis causes changes in corneal biomechanics can be explored, and sensitive mechanical indicators of allergic conjunctivitis can be identified. Furthermore, through rubbing frequency, ocular allergic symptom scores and physical sign scores observation, corneal morphological parameters, corneal epithelial thickness, tear inflammatory cytokines levels, and conjunctival microvascular parameters measurements, related factors affecting corneal biomechanics in patients with allergic conjunctivitis can be identified. Otherwise, by comparing corneal biomechanical changes in vernal keratoconjunctivitis before and after drug treatment, biomechanical change tendency during treatment can be clarified.

The aim of this study is to assess the virus RNA, and miRNA levels related to viral infection, and inflammatory response in tears of hospitalized patients with a diagnosis of COVID-19 with and without conjunctivitis and to correlate them with clinical condition. Tears will be collected by using Schirmer Test I, a non invasive painless test which can be performed at the patient's bed. Tears will be collected on the graduated paper strips pulling the lower lid gently downward for 5 minutes. Following, the strip will be placed in a 2.0 mL Eppendorf tube and stored at -80◦C (or - 20°C)

The DRy eye Outcome and Prescription Study (DROPS) is a large observational multicentre study exploring the 'real world' effectiveness of artificial tears in dry eye disease and determinants of efficacy. The aim is to include at least 635 symptomatic dry eye patients who are prescribed artificial tears. All trainees and fellows in London are invited to become collaborators: collaborators are asked to consent patients, assess signs at baseline, and give patients questionnaires at baseline and 4 weeks (for home completion). In tandem, we are conducting a qualitative review of ophthalmologists' prescribing behaviours for dry eye disease.

The purpose of this protocol is to provide compassionate use of Kedrion Human Plasminogen Ophthalmologic Drops to an expanded population of patients diagnosed with ligneous conjunctivitis associated with type I Plasminogen deficiency until product licensure, and/or until a new clinical trial is available and the patients in treatment under Expanded Access are eligible to participate in the new trial.

This study is the first multi-center cross-sectional study on the diagnosis and misdiagnosis of allergic conjunctivitis in the ophthalmology clinic in China. It provides a clinical basis for the standardized diagnosis and treatment of allergic eye diseases.
