OBJECUIVE: To observe the therapeutic efficacy of gamma;-knife/lymphokine activated killing cells (LAK)in chorold malignant melanoma (CMM). METHODS:Five cases of CMM had keen treated by retrobulbar injection of LAK cells and gamma;-knife irradiation at multiple sites.Ophthalmologic,imageologic, fundus fluorescein angiographic and T lymphocyte subset examinations were done before and after treatment. Tile follow-up period of this series of cases was 6-24 months. RESUILS:Thc CMM of 4 in 5 treated cases became atrophic and withered up clinically after gamma;-kinfe/LAK therapy. Among the 4 cases,2 of them had been followed up for more than 2 years,and the other 2 for 20 and 14 months respectively. The tumor of the 5th patient wko was followed up for 6 months after treatment,reduced to 3/5 of the original size,and no blood flow was found within thee tumor mass under the clinical examination. CONCLUSION :The gamma;-knife/LAK therapy was effective in treating CMM in saving the affected eye from being enucleated. Chin J Ocul Fundus Dis,1997,13: 96- 98）
Objective To investigate the characteristics of the ocular fundus of Chinese patients with polypoidal choroidal vasculopathy (PCV).Methods The photographs of ocular fundus of 42 Chinese patients (48 eyes) with PCV diagnosed by fundus photography, fundus fluorescein angiography (FFA), and indocyanine green angiography (ICGA) were analyzed.Results In 48 eyes with PCV, 35 (72.9%) had subretinal hemorrhage, 13 (27.1%) had yellow-white exudation, 7 (14.6%) had subretinal tuberculum-like focus in tangerine peel at the posterior pole, and 26 (54.2%) had hemorrhagic or serous pigment epithelium detachment (PED). Thirty-six eyes（75.0%）had polypoidal dilations with branching vascular network, and the other 12 (25.0%) had scattered polypoidal dilations without identifiable continuous branching vascular network. The location for these lesions were at the macular region in 30 eyes (62.5%), arcade region in 6 (12.5%), peripapillary region in 3 (6.3%), and combination region in 9 (18.8%).Conclusions Most of the lesions in Chinese patients with PCV locate at the macular region and temporal vascular arcade. Most eyes are characterized by branching choroidal vessels with polyplike terminal aneurysmal dilations in ICGA. (Chin J Ocul Fundus Dis，2003，19：269-332)
Purpose To observe the features of the hyperfluorascent areas in the posterior ocular fundus detected by indocyanine green angiography(ICGA) in healthy volunteers, and to study circulatory properties of choroid. Methods Routine ICGA was performed on each of fifty consecutive normal eyes. Results ⑴Hyper fluorescence began at an average time of (30.80plusmn;5.42) seconds. ⑵The patterns of the hyperfluorescence revealed themselves in doubling areas divided symmetrically by the relatively hypoer fluorescence blelt running horizontally across the fovea in 29 eyes(58%), and single area in 21 eyes(42%).⑶The average area of the hyper fluorescence was (57.27plusmn;14.08)mm2.⑷ The sustaining time of the hyper fluorescence was (172.44plusmn;59.70) seconds at average. Conclusion During ICGA, a very patchy filling pattern of hyper fluorescence was visible in posterior fundus in normal eyes, and its filling time and shape presented choroidal blood supply and circulation. These parameters would offer consulted bases for clinical diagnosis of the choroidal diseases. (Chin J Ocul Fundus Dis,1999,15:1-3)
