Clinical trials

Dysregulation of the Angiopoietin-2 (Ang-2)/Tyrosine kinase with Immunoglobulin-like and EGF-like domains 2 (Tie-2) signaling pathway has been implicated in choroidal vascular instability and RPE dysfunction in Central serous chorioretinopathy (CSCR) and pachychoroid-associated neovascularization. This study prospectively evaluates the efficacy and safety of faricimab compared to sham in CSCR with and without secondary neovascularization, using standardized anatomical and functional endpoints. The results of this trial may help define the role of dual pathway inhibition in CSCR and inform future treatment strategies for this challenging and vision threatening condition.

The purpose of this research study is to evaluate a new screening procedure for the early detection and monitoring of Age-related Macular Degeneration (AMD) in community settings and community hospital settings, to identify associated risk factors, and develop personalized monitoring strategies for at-risk individuals throughout the 5 years follow up period, which will allow us to establish prevalence, natural history of progression of early AMD in the community.

This study is about understanding how a condition called pachychoroid changes over time. Pachychoroid refers to an anatomic choroidal characteristic with abnormally thick choroid or abnormally dilated Haller's vessels. Pachychoroid can range from mild forms which does not cause any problems to more serious ones that might cause vision loss.This study will recruit participants with pachychoroid, to learn more about how this condition develops, how it affects people in the long run, and what factors might make it worse.

The bulk of dry eye patients are found in the community. The lack of satisfactory protocols and confidence is a significant deterrent for practitioners to manage such patients, which may result in inaccurate referrals, and unhappy patients. Problems are compounded by comorbidities of dry eye, even if these are not diagnosed formally. Aligning with the healthcare strategy to move beyond healthcare to health, and beyond hospital care to community care, investigators propose that the confidence of primary carers be increased by using an image-based screening system. This study aim to determine the efficacy of this screening AI algorithm, a prototype, in addition to or instead of screening of dry eye using a simple DEQ-5 symptom questionnaire.

Dry eye disease (DED) is a common eye condition that is becoming more widespread. Detecting it early, keeping track of its progression, and following up regularly can help protect vision and prevent serious complications. However, due to a shortage of ophthalmologists, limited access to eye care services, and disparities in care quality, many patients receive infrequent or insufficient clinical consultations. To address these needs, a portable automatic ocular surface imaging device (PAOSID) that attaches to a mobile phone has been developed. This device uses three types of light including white, infrared, and cobalt blue light to capture clear images and videos of the eye's surface. It also has a smart system that automatically takes high-quality images, allowing patients to use it at home independently. This device may help detect early signs of DED and monitor eye health more easily.

The purpose of this research study is to understand the mechanism of action of low level light therapy and also potentially yield markers associated with good treatment response. Low-level light therapy is light-based treatment delivered through advance eye-light device. This therapy uses light energy to provide energy to the meibomian gland cells to slow down age-ing, improve tear stability and reduce inflammation.

This study aims to understand how blood flow at the back of the eye changes over time after this surgery. By studying these changes, the investigators hope to gain insights that could help improve the understanding of other eye diseases, such as age-related macular degeneration (AMD) and polypoidal choroidal vasculopathy(PCV). This research may contribute to better treatments and outcomes for future patients.

Neovascular age-related macular degeneration (nAMD), also called wet AMD, can cause serious vision loss. While anti-VEGF (anti Vascular Endothelial Growth Factor) treatments such as ranibizumab help many patients, about 20 40% have a suboptimal response. In this study, the investigators want to identify other factors (beyond VEGF) that might be driving the disease in these non-responding patients. By looking at samples from inside the eye (vitreous humor) and comparing "good responders" to "suboptimal responders", the investigators hope to find potential new treatment approaches or biomarkers for nAMD.

Assess the effect and changes of eye misalignment (strabismus) with myopia control glasses Assess the efficacy of myopia control glasses on childhood myopia progression in children with strabismus due to the uncertainty clinicians face when prescribing myopia control glasses to these strabismic children

The aim of the study is to explore efficacy of combination Atropine and multifocal CL. Randomized Control Trial including 4 arms: Atropine / multizonal CL; Atropine/ SV CL, Placebo drop/ multizonal CL; Placebo drop/ SV CL. Followed over 1 year with outcome measure of change in spherical equivalent and axial length.

This clinical study aims to evaluate the non-inferiority of the photochromic DIMS spectacles lenses performance (PDIMS) compared to clear DIMS spectacles lenses (DIMS) in myopia management.
