AIM
To assess the centre of fixation before laser photocoagulation of well defined juxtafoveal or extrafoveal choroidal neovascularisation (CNV) secondary to age related macular degeneration (AMD), and to better predict visual function after treatment using scanning laser ophthalmoscope (SLO) fundus perimetry.
METHODS
19 consecutive eyes with juxtafoveal or extrafoveal CNV were examined by fundus perimetry before and after laser treatment with documentation of the fixation point using the SLO. The stability of fixation was defined as standard deviation around the mean fixation point. Overlays of fluorescein angiographic pictures and fundus perimetry were obtained using image analysis software.
RESULTS
Fundus perimetry allowed accurate determination of the centre of fixation. Overlays demonstrated the precise geographic relation of the angiographically detectable foveal margin of the CNV and the centre of fixation. Thereby, prediction of the visual outcome with regard to reading ability was facilitated. Stability of fixation did not change significantly after treatment.
CONCLUSIONS
Fundus perimetry using the SLO was helpful in patients who underwent laser treatment for juxtafoveal or extrafoveal CNV secondary to AMD and may aid the pretreatment counselling of such patients.
目的
评估年龄相关性黄斑变性（AMD）继发的明确的黄斑旁或黄斑外脉络膜新生血管（CNV）在激光光凝治疗前的注视中心，并使用扫描激光检眼镜（SLO）眼底视野计更好地预测治疗后的视功能。
方法
对19只连续的黄斑旁或黄斑外CNV患眼在激光治疗前后进行眼底视野计检查，使用SLO记录注视点。注视稳定性定义为平均注视点周围的标准差。使用图像分析软件获得荧光素血管造影图片和眼底视野计的叠加图。
结果
眼底视野计能够准确确定注视中心。叠加图显示了CNV血管造影可检测到的黄斑边缘与注视中心的精确位置关系。从而有助于预测阅读能力方面的视觉结果。治疗后注视稳定性没有显著变化。
结论
使用SLO的眼底视野计对接受AMD继发的黄斑旁或黄斑外CNV激光治疗的患者有帮助，并且可能有助于对此类患者进行治疗前咨询。
