Comparative Study on the Efficacy and Safety of Tumor Resection in Vitrectomy for Retinal Vasoproliferative Tumors

Figure 5

HE staining of case 14. (a) Microscopically, the tumor was involved in the inner layers of the retina, and some of the inner nucleus layer structure was broken off. Boundary between the tumor and retina was unclear (×40). (b) Glial cells arranged in a staggered weave around the hyaline degenerative vessels (×100). (c) In the inner side of retina, hyperplastic small vessels, hyaline degenerative vessel wall, and interstitial infiltration of little lymphocyte can be observed (×100). (d) High magnification showed that the proliferating glial cells were bipolar spindle cells with interlaced arrangement. The nucleus was oval or short fusiform, with fine chromatin. The nucleolus was not obvious or there were no nucleoli (×200).
