NCT07267481
To determine the efficacy of switching participants who are being treated with Xiidra to acoltremon 0.003%. Hypothesis: Switching to acoltremon 0.003% will greatly improve the signs and symptoms of participants who were being treated with Xiidra at 28 days post-treatment compared to baseline.
NCT07228793
This natural history study of patients with EYS mutations from Russia and former CIS (Commonwealth of Independent States) territories will accelerate the development of outcome measures for clinical trials. Sensitive, reliable outcome measures of retinal degeneration will greatly facilitate development of treatments for retinitis pigmentosa due to EYS mutations. This approach helps to develop experimental treatment protocol, and assessing its effectiveness. The goals and expected impact of this natural history study are to: 1. Describe the natural history of retinal degeneration in patients with biallelic mutations in EYS gene in Russia and former CIS territories. 2. Identify sensitive structural and functional outcome measures to use for future multicenter clinical trials in EYS-related retinal degeneration in Russia and former CIS territories. 3. Identify well-defined subpopulations for future clinical trials of investigative treatments for EYS-related retinal degeneration in Russia and former CIS territories.
NCT06177639
The goal of this observational study is to test the use of a novel Widefield Confocal Scanning Laser Ophthalmoscope (WiSLO) Optimized for Pediatric and Neonatal Imaging in pediatric and adult subjects who are undergoing clinical evaluation for eye disease or are healthy adult volunteers. The main questions to answer are: * Whether WiSLO will be more comfortable and satisfactory in experience for the patient and operator than commercial alternatives. * If the quality of WiSLO near infrared images will be comparable to color fundus camera imaging across population of different ages and fundus pigmentation. Participants will have the following research procedures: * Imaging of both eyes with a research noncontact WiSLO * Imaging of both eyes with a commercially available non-contact hand held fundus camera (Volk Pictor Plus) * Likert scales for adults * Pediatric Likert scales for children * CRIES scales for infants.
NCT06841575
The goal of the current study is to conduct a pilot study to test a new version of the handheld OCT device capable of auto-alignment to image the retina in adult volunteers, and adult and pediatric patients in clinic.
NCT05797896
An observational study to investigate the natural history and evaluate biomarkers of participants with geographic atrophy secondary to age-related macular degeneration
NCT05147701
This trial will study the safety and efficacy of intravenous and sub-tenon delivery of cultured allogeneic adult umbilical cord derived mesenchymal stem cells for the treatment of non-arteritic ischemic optic neuropathy
NCT05550740
The purpose of this clinical trial is to confirm the incidence and magnitude of axial length shortening after RLRL therapy in Chinese high myopia children and teenagers.
NCT06045299
A Multi-Center, Randomized, Double-Masked, Placebo-Controlled Phase 3 Evaluation of the Efficacy and Safety of LNZ101 and LNZ100 for the Treatment of Presbyopia
NCT06112340
The overall study objective is to continue to assess the efficacy, safety, pharmacokinetics, and pharmacodynamics of linsitinib in subjects who were enrolled in the prior VGN-TED-301 through Week 24. These subjects include VGN-TED-301 Week 24 proptosis non-responders or subjects who relapse during the Follow-Up Period of VGN-TED-301.

Rare Eye Diseases (RED) are the leading cause of severe visual impairment/ blindness (SVI/B) in children in Europe. This sensory disability with its accompanying psychological distress hugely impacts their lives and their families. Understanding this impact, at a patient centred level, is key in care, in shared decision making, in developing therapies, and in improving social integration and participation about the standard rules of the United Nations (UN) and the European Union (EU) (prevention, non-discrimination, equal opportunities, accessibility, etc.). However, current tools to evaluate vision related (VR) quality of life (QoL) VR-QoL disregard age and cultural differences. There is a lack knowledge on how the disease matters at child's level. Instruments capable of yielding high-quality data, psychometrically robust and comply with regulatory requirements remain to be developed. To fill this gap, SeeMyLife will use multilevel concurrent mixed method research combining quantitative studies and qualitative studies. The quantitative approach is based on (i) cross culturally translated validated VR-QoL questionnaires for children and teenagers (Functional Vision Questionnaire for Children and Young People - FVQ-CYP and Vision-related Quality of Life Questionnaire for Children and Young People - VQoL-CYP) and (ii) on caregiver's questionnaires addressing participation and environment (Participation and Environment Measure - Children and Youth - PEM-CY). To fully capture the picture of the child/teenager personal life the investigators will reinforce their investigations by in depth qualitative socio-anthropologic study with semi directive field interviews and fieldwork (to observe closely the living conditions of the children) to address how their impairment affects their wellbeing, social integration, and how they feel about medical and social interventions. Data analysis will use an integrated mixed method strategy to validate the quantitative tools and deliver a holistic QoL transnational tool. The SeeMyLife project will provide (i) robust patient self-reported tools that will be then used in care and research (especially with the rise in novel therapies) as a standard as well as (ii) highly awaited knowledge about the SVI/B patient's position within his own life course, within his family and in relation to health and social care actors.
NCT06451172
The purpose of this study is to evaluate the safety and efficacy of GP-asPNA for in vivo treatment of severe antibiotic resistant bacterial keratitis.
NCT06255301
In order to develop innovative biomarkers for the diagnosis of two ocular surface pathologies, Dry Syndrome (DS) and Limbic Stem Cell Deficiency (LSCD), human cells from the ocular surface will be collected in order to test these biomarkers ex vivo.
NCT02946879
This study is a longer-term follow-up study for patients who have been administered AAV2/5-OPTIRPE65 in the Phase I/II, open label, non-randomised, two-centre, dose escalation trial in adults and children with retinal dystrophy associated with defects in RPE65.
NCT04668924
The purpose of this study is to evaluate the efficacy, safety and postoperative ocular discomfort by individually customized Photorefractive intrastromal crosslinking (PiXL) without epithelium debridement in high oxygen environment (Epi-on) for progressive Keratoconus.
NCT03990506
The purpose of this study is to evaluate the efficacy, safety and postoperative ocular discomfort by comparing individually customized Photorefractive intrastromal crosslinking (PiXL) for progressive Keratoconus. The study compares two different protocols, PiXL with corneal epithelium debridement (Epi-off) and PiXL without epithelium debridement in high oxygen environment (Epi-on), with the hypothesis that Epi-on gives less postoperative ocular discomfort.

To readdress basal cell carcinoma (BCC) in the periocular region to prove histologically controlled surgical treatment efficacy and to identify high-risk characteristics.
NCT05717543
Retroillumination photography is difficult. The reflections on the cornea and the lens are constant and prevent from obtaining a complete and clear image. Study team have modified a slit lamp intended to photograph the anterior segment of the eye in retroillumination by using a light source in the near infrared (780 nm), and a process which eliminates the reflections.
