The diagnosis of CSR usually starts with a dilated examination of the retina, followed with confirmation by fluorescein angiography. The angiography test will usually show one or more fluorescent spots with fluid leakage. In 10%-15% of the cases these will appear in a “classic” smoke stack shape (Figs 2 & 3). An Amsler grid could be useful in documenting the precise area of the visual field involved.
