本研究的优势在于操作简单、安全、可重复、疗效明显，但也有不足之处，有几

The advantages of this study are simple operation, safety, reproducibility, and obvious curative effect, but there are also shortcomings. There are several limitations. First, the sample size is small. In this study, the small sample size may cause standard deviations. The conclusion may cause errors, and the next study needs to further expand the sample size; second, there is no control group in this study, which cannot fully evaluate the real effect of anti-VEGF treatment;
