1963年 Agarwal 等将外直肌通过巩膜做成的燧道植于巩膜与脉络膜之间,以增加脉络膜的血液供给治疗原发性视网膜色素变性。在15只眼施行了这种手术,观察到手术侧眼底表现充血,出血及白色渗出物,2只眼的脉络膜有新生血管,9只眼的视力进步1~3行(snellen 视力表)。作者用正常的兔子做实验以研究是否脉络膜有新生血管抑或在脉
In 1963, Agarwal et al. Established a translucency of the lateral rectus through the sclera between the sclera and the choroid to increase the choroidal blood supply for the treatment of primary retinitis pigmentosa. The operation was performed in 15 eyes. Congestive, hemorrhagic, and white exudates were observed in the ocular fundus of the operated side. The choroid of two eyes had neovascularization. The visual acuity of 9 eyes improved by 1 to 3 lines (snellen visual acuity chart). The authors used normal rabbits to experiment with choroidal neovascularization or in the pulse
