Abstract Details


To compare visual field defects of patients (eyes) with peripapillary choroidal neovascularization (CNV) treated with laser photocoagulation with visual field defects of patients treated with anti-VEGF therapy.


Eye Hospital, University Medical Centre Ljubljana, Grabloviceva 46, 1000 Ljubljana, Slovenia


Microperimetry results of 5 patient with peripapillary CNV treated with laser photocoagulation between 2007 – 2009 and microperimetry results of 5 patients treated in recent years with anti-VEGF therapy were compared with colour fundus, fluorescein angiography and OCT images. All patients had at least three-year follow-up after end of treatment.


All patients had absolute scotoma that corresponded to the peripapillary scar. Area of the scar was greater than area of active CNV lesion before therapy in patients treated with laser photocoagulation. Relative scotomas corresponded to areas of haemorrhage and in some cases to serous detachment when CNV was active in both groups of patients. These areas corresponded to defects in elipsoid zone on OCT images after formation of the scar. Subjectively, there was no difference in visual field defect before and after therapy regardless treatment modality used.


Both treatment modalities induce scar formation with visual field defect. Laser photocoagulation induces iatrogenic damage to the retina, but can still be considered as an treatment option in certain group of patients.
