简要总结
To explore an optimized scan technique for the detection of lid margin vasculature
详细描述
To investigate whether the SS-OCTA tool has the potential to characterize the lid margin vascularity in MGD patients. The repeatability and validity of OCTA in assessing eyelid margin blood flow density was evaluated。

入选标准
- •The MGD patients were aged >_20 years and were diagnosed according to Chinese MGD diagnostic criteria,11 including dry eye symptoms, and at least one of the following signs: (1) poor meibum expressibility or quality; (2) at least one of eyelid margin abnormalities (lid margin irregularity, plugging of the gland orifice, vascular engorgement/telangiectasia, and anterior replacement of the mucocutaneous junction. Normal subjects were defined as adults without any dry eye symptoms and lid margin abnormality.
排除标准
- •(1) subjects with ocular diseases or conditions known to affect the anatomy of the anterior segment, such as acute ocular inflammation, a history of eyelid surgery, contact lens wear within two weeks, and/or eyelid trauma; (2) subjects with of history of systemic or topical medications that might cause ocular congestion; (3) subjects with severe systemic illness or pregnancy; and (4) subjects who were difficult to cooperate with examination, resulting the obtained images were not sufficiently clear for automatic analysis.
