目的:描述第三级转诊中心15a期间局限性脉络膜血管瘤(CCH)患者光动力疗法的临床经验。方法:对1992/2007年第三级转诊中心确诊(基本数据和摄影记录为主要确诊依据)为局限性脉络膜血管瘤患者进行记录。结果:患者11例(69%)视力改善(>2行),1例(5%)患者视力保持稳定,4例(25%)患者恶化。6/7患者采用放疗的方法和3/4采用瞳孔温热疗法治疗均获得了良好的效果。86%的患者发病6mo内进行治疗和50%的患者发病6mo后进行治疗视力有明显的改善。只有一个患者视力<6/60。平均随访时间为35mo。结论:发病6mo内进行治疗的患者效果较好。多数患者经过治疗后视力显著改善且无任何不良影响。

AIM:To describe our clinical experience in treating circumscribed choroidal haemangioma(CCH)in a tertiary referral centre over a fifteen year period prior to photodynamic therapy.·METHODS:The departmental database and photographic records of a tertiary referral center were used to identify patients who were treated for CCH between 1992 and 2007.Their case records were reviewed.·RESULTS:Visual acuity improved(>2 Snellen lines)in eleven patients(69%)remained stable in one patient(6%)and deteriorated in four patients(25%).Six of the seven treated with brachytherapy and three of the four treated with transpupillary thermotherapy achieved better visual acuity after treatment.86% of patients treated within six months of onset of symptoms and 50% of patients treated after six months of onset of symptoms noted an improvement in visual acuity.Only one patient in our series had a final VA of 6/60 or worse.Mean follow-up was thirty-five months.·CONCLUSION:Visual outcome is better when treatment is performed within 6 months of symptoms.The majority of patients achieved an improvement in visual acuity without any adverse effect following treatment.·
