Retinoblastoma, the most frequent malignant intraocular tumor in childhood, is caused by oncogenic mutations in the RB1 tumor suppressor gene. Identification of these mutations in patients is important for genetic counseling and clinical management of relatives at risk, and thus probands are conventionally applied gene detection in developed countries. However, gene diagnosis is still in the elementary period in China. This article reviews the characteristics of retinoblastoma genetics and the current status of genetic testing in China, so as to attract more attention from ophthalmologists and to promote regulated gene diagnosis in clinical work. Not only does good understanding of retinoblastoma genetics support optimal care for retinoblastoma children and their families, but also promotes the development in foundational research.

The filtration bleb dependent surgeries, such as trabeculectomy, are the main methods for glaucoma treatment in China. However, the filtration bleb scarring after the surgery has always been a challenge to long-term results. In recent years, with the application of anti-glaucoma non-filtering bleb dependent surgery, the surgery complications of filter bubble dependence have been avoided, such as shallow anterior chamber and leakage of filtering bleb. Researches are still needed on the indications, long-term effects and health economics evaluations. It also takes time to widely popularize its application in China. This article focuses on comparing the filtration bleb dependent surgeries with non-filtering bleb dependent surgeries to deeply state the characteristics, advantages and disadvantages of the two methods.
