Overview
The RBBK study is a non-interventional, prospective study that will characterize disease state biomarker levels from aqueous humor, vitreous humor, intraoperative tissue and saliva of subjects with various retinal and systemic pathologies.
Detailed description
The RBBK study is a non-interventional, prospective study that will characterize disease state biomarker levels from aqueous humor, vitreous humor, intraoperative tissue and saliva of subjects with various retinal and systemic pathologies.
Participants are eligible to be included in the study only if all of the following criteria apply:
1. Men or women \> 18 years of age 2. Subjects with vitreoretinal disease in at least one eye receiving a retinal treatment intervention 3. Able and willing to provide signed informed consent
The study will consist of a single visit and a retrospective chart review. The study visit will consist of:
1. Screening for eligibility; 2. Aqueous humor collection (if applicable); 3. Vitreous humor collection (if applicable); 4. Intraoperative tissue (if applicable); and 5. Saliva collection
If applicable, approximately 50 microliters (or more, up to 1000 microliters) of aqueous fluid will be collected by anterior chamber paracentesis according to standard clinical procedures. If applicable, up to 2 milliliters of vitreous fluid will be collected according to standard clinical procedures. Specific tissue, such as scar tissue, are routinely removed from the eye during vitreoretinal procedures. When being removed during a standard of care surgical procedure, these tissues may be collected. Saliva will also be collected according to instructions found in the Saliva Oragene Dx Collection Kit.
Primary outcome measures
- To quantify levels of disease state biomarkers implicated in the pathogenesis of various retinal and systemic pathologies [Time frame: Baseline]
