目的：探讨不同病变阶段视网膜色素变性患者的脉络膜血管状态。方法：回顾性分析云南省第二人民医院眼科2000年1月至2015年4月诊断为原发性视网膜色素变性的患者226例(452眼)的眼底特征，并复习相关文献，重点分析总结脉络膜血管情况。结果：31例(62眼)病变前期患者，荧光素眼底血管造影显示动脉期脉络膜血管及视网膜血管充盈正常，未出现充盈延迟或缺损现象。25例(50眼)病变早期患者，荧光素眼底血管造影显示动脉前期可见脉络膜背景荧光显示，部分脉络膜毛细血管未同时充盈，动脉期时上述部分完成充盈。106例(112眼)病变中期患者，荧光素眼底血管造影显示动脉期出现部分脉络膜毛细血管萎缩区，仅能看到残存的粗大脉络膜血管，随造影过程的进展，此区域并未出现充盈，即呈现永久的脉络膜毛细血管充盈缺损。64例(128眼)病变晚 期患者荧光素眼底血管造影显示，广泛的脉络膜毛细血管萎缩区，其间可见残存的脉络膜粗大血管，至造影晚期均呈现充盈缺损，萎缩区边缘随造影过程呈强荧光表现。结论：荧光素眼底血管造影可显示脉络膜血管萎缩变化情况，这一指标可作为反映不同病变阶段视网膜色素变性患者病情进展变化的重要依据。

Objective: To investigate clinical characteristics of choroid in different stages of retinitis pigmentosa. Methods: The characteristics of fundus, visual conditions and characters of choroid of 226 cases (452 eyes) patients with retinitis pigmentosa in No. 2 People’s Hospital of Yunnan Province from Jan.2000 to Apr.2015 were retrospectively analyzed. Results: Fundus fluorescein angiography of 31 cases (62 eyes) before early stage showed:  arterial choroidal and retinal vascular filling normal, filling delay or defect phenomenon does not be observed. Fundus fluorescein angiography 25 cases (50 eyes) patients in early disease showed: preliminary choroidal artery background fluorescence was displayed, at the same time, part of the choriocapillaris was not filling, the filling was completed in arterial stage. Fundus fluorescein angiography of 106 cases (112 eyes) patients in the medium-stage showed: arterial phase appears part choriocapillaris atrophy area, thick choroidal vessels can be seen, with the progress angiography procedure, filling was not be observed in this area, which presents permanent choriocapillaris filling defect. Fluorescein angiography of 64 cases (128 eyes) in patients in advanced stage showed widespread choriocapillaris atrophy area, during which thick choroidal vessels remaining filling defect in late stage, atrophic area with a contrast edge high fluorescence performance. Conclusion: Fluorescein angiography can show choroidal atrophy changes, it can be used as an indicator to assess the progression of retinal changes in patients with retinitis pigmentosa.

目的：探讨大泡性角膜病变(bullous keratopathy，BK)患者行飞秒激光辅助的角膜内皮移植术(endothelium keratoplasty，EK)的围手术期护理。方法：回顾性分析在南京总医院眼科行飞秒激光辅助角膜内皮移植的BK20例患者，分析并总结患者术前的心理疏导、术前准备、眼科检查、术中如何配合医生、术后特殊体位、高眼压的护理及如何正确用药和出院健康教育等。结果：患者得到及时、有效的护理，术后视力均有所提高，内皮贴伏好，无排斥反应及其他并发症的发生。结论：通过对患者围手术期的护理，可提高护理质量，缩短患者住院时间。

Objective: To observe the perioperative nursing of femtosecond laser-assisted corneal endothelial transplantation in the treatment of patients with bullous keratopathy. Methods: A retrospective analysis of 20 patients with bullous keratopathy with femtosecond laser-assisted corneal endothelial transplantation in our department. The preoperative psychological counseling, preoperative preparation, ocular examination, how to cooperate with the doctors in operation, nursing of special position, high intraocular pressure after surgery, how to use eye drops correctly and health education after discharge were summarized. Results: Nursing were performed to the patients timely and effectively. Postoperative visual acuity of all the patients were improved, the endothelial and corneal stroma bed are well combined and no graft rejection and other complications occurred in the patients postoperatively. Conclusion: We concluded that the quality of nursing was improved and the time of hospitalization was shortened after perioperative nursing.
