Analysis of Risk Factors for High Intraocular Pressure and Retinal Detachment Recurrence After Vitrectomy with Silicone Oil Tamponade in Retinal Detachment Patients
This study is a retrospective study. Patients who visited the ophthalmology clinic of the First Affiliated Hospital of Chongqing Medical University between September 1, 2024, and December 31, 2025, will be screened according to the inclusion and exclusion criteria mentioned below. After obtaining informed consent, clinical data of the subjects …
Retinal Neurovascular Coupling in Patients Previously Infected With COVID-19
The Study objective is to measure retinal neurovascular coupling and blood flow parameters in patients previously infected with COVID-19, long COVID-19 and healthy ageand sex- matched control subjects
Effect of the Stellate Ganglion Block on the Retinal Microcirculation
Surges in the sympathetic nervous system occur at the ictus of a variety of neurological critical illnesses including intracranial hemorrhage and ischemic stroke. It is hypothesized that these exaggerated increases in sympathetic nervous activity produce maladaptations that promote secondary brain injury. One of these possible mechanisms include diffuse vasospasm that …
Retinal OCTA for Microvascular Dysfunction Evaluation and Outcome Prediction in MINOCA Patients
The aim of this study is to evaluate microvascular dysfunction through OCTA in MINOCA patients. In order to better understand the condition, OCTA will also be performed in two matched patient groups: healthy controls and ACS patients. The study will compare the retinal microvascular parameters across these groups to determine …
Color Vision Loss and Retinal Changes Correlation, and a Novel Color Test
This prospective, observational investigation seeks to delineate the interplay between chromatic vision deficits and both functional visual outcomes and anatomical retinal biomarkers in individuals affected by Inherited Retinal Dystrophies (IRDs). The study will recruit approximately 200 subjects, encompassing a heterogeneous population of IRD patients-spanning a range of genotypes and clinical …
Retinal Vascular Manifestations in Patients With Common Internal Diseases on OCTA Tomography Angiography
Hypertension, diabetes mellitus, and dyslipidemia are common internal diseases, and all diseases are atherosclerosis risk factors. Previous studies applied color fundus photography to analyze retinal vascular changes (including exudation, hemorrhage, neovascularization, etc.) in patients with hypertension or diabetes, but the examination results could not be quantified. This study intends to …
Characterizing the Retinal Microvasculature in Patients with Fabry Disease: a Prospective Observational Study
This study aims to gain a deeper understanding of endothelial dysfunction in patients with Fabry disease through a prospective study of the retinal microvasculature and to identify an objective, non-invasive marker to assess disease severity and cardiovascular risk in patients. The main questions addressed are: Do dynamic and static retinal …
VIsual Cerebral ConnecTivity On Functional Magnetic Resonance Imaging in Patients With Hereditary REtinal Dystrophies
The Rothschild Foundation A Hospital follows a cohort of approximately 300 patients with hereditary retinal dystrophy. These patients are followed in ophthalmology consultation every year. In order to plan the MRI on the day of the annual consultation and to avoid additional travel for patients, patients will be informed of …
Observational Study to Assess Endpoint Operational Feasibility & Measurement Properties in Patients with Retinal Degeneration
The Vision Research and Assessment Institute (VRAI) was established with the purpose of serving as a testing facility for efficacy endpoints for patients with Low Vision. The mission of the VRAI is to enable the highest quality, standardized efficacy testing of patients with visual impairment. The VRAI facilitates the development …
Effects of Change in Blood Pressure on Retinal Capillary Rarefaction in Patients With Arterial Hypertension
To evaluate whether in patients with initially poorly-controlled arterial hypertension, structural and functional differences in the retina and choroid remain after achieving a well-controlled blood pressure.
