The goal of this observational study was to learn about metabolomics profiles in vitreoretinal diseases by nuclear magnetic resonance (NMR)using vitreous fluid. The main question it aimed to answer was abnormal biomarkers for common retinal diseases such as idiopathic macular hole(IMH), diabetic retinopathy(DR) and retinal detachment(RD). Participants would not be subjected to any intervention and the investigators would only collect preoperative information and remaining vitreous samples. The investigators divided the participants into groups with appropriate disease names based on the disease diagnosis, such as IMH group, DR group, and RD group. The MH group was used as a control group, investigators compared other groups to see the metabolomic abnormalities.

Primary outcome measure(s)
Relative amino acid concentration(Unite: %) — intraoperative NMR provides spectral data to show the relative concentration of various amino acids, and the use of NMR to measure vitreous humor and compare changes in amino acid content across disease species leads to speculation about biological markers of disease progression.
