Clinical Trial Summary

This study is a comparison of multifocal electroretinogram assessment between the laser treatment group and the photodynamic therapy group in chronic central serous chorioretinopathy.


Clinical Trial Description

1. Laser Group: extrafoveal focal leakage on FAG

2. PDT Group: no definite focal leak on FAG subfoveal or juxtafoveal focal leakage on FAG, or serous retinal pigmentary epithelial detachment involving foveal center

Inclusion criteria

1. Chronic serous chorioretinopathy (over 3 months) when subretinal fluid persisted in the subfoveal region demonstrated by clinical examination and OCT

2. Ability to maintain steady fixation for mfERG

3. Presence of abnormal dilated choroidal vasculature in ICGA

4. Symptom duration over 3 months

Exclusion criteria

1. previous PDT or laser treatment history

2. evidence of Choriinal neovascularization in FAG

3. other chorioretinal disorders that can cause macular exudation such as age-related macular degeneration, pathologic myopia, angioid streaks, trauma, inflammatory diseases, retinal vasculopathies, and hereditary dystrophies

follow-up Visit
