Feasibility and Safety of MB-102 in Ocular Angiography as Compared to Fluorescein Sodium

The objective of this study is to evaluate the safety and image quality of the investigational dye, MB-102, compared to the control dye (fluorescein sodium) in healthy and diseased eyes using fluorescent angiography for retinal vascular disease diagnosis and monitoring.

Study of the Involvement of Fatty Acids in Retinopathy of Prematurity: Relationship Between Retinopathy of Prematurity and the Rate of Expression of Transplacental Fatty Acid Receptors.

The development of the retinal vascular network is completed during the third trimester of pregnancy and and the first 15 days of life of the newborn. This late maturation can be problematic in cases of preterm births and result in immature retinal vascularization, known as retinopathy of prematurity (ROP). Among the various factors influencing retinal vascular development, the tissue content of omega-3 polyunsaturated fatty acids (PUFAs) appears to be a crucial element. In a previous project, OMEGA-ROP, we showed a difference in the blood bioavailability of omega-3 PUFAs in infants born at less than 28 weeks of amenorrhea who develop ROP compared to healthy newborns with no retinopathy. This study also showed that mothers experienced variations in the blood levels of omega-3 PUFAs that were contrary to the types of variations observed in their children. This suggests a sequestration of omega-3 PUFAs in the mothers of children who will develop ROP. This new project aims to better understand the underlying molecular mechanisms by studying the expression levels of placental fatty acid receptors in relation to the development of ROP in newborns.

Cognitive Impairment, Retinopathy, and Cerebrovascular Lesions in the Elderly

The CIRCLE study is a single-center prospective observational study that enrolled individuals with cerebral small vessel disease (SVD), while free of known dementia or stroke (both cerebral infarction and hemorrhage). The patients will receive neuropsychological testing, retinal digital images and multimodal magnetic resonance imaging (MRI). Blood samples will also be collected. Recent small subcortical infarcts, lacunes, white matter hyperintensities, perivascular spaces, microbleeds, and brain atrophy will be evaluated on both baseline and follow-up brain MRIs. The investigators will explore the predictors of preogression of SVD and cognitive deficits.
