Abstract
Macular disturbances in patients with active idiopathic central serous retinopathy can be readily documented by performing Amsler charting or static perimetry, but, as uncertainty exists as to which examination technique is superior for detecting disturbances after a detachment has settled, a study was performed in which patients were investigated by the two methods during the acute, resolving and resolved stages of the disease. All of the patients assessed in the acute phase showed abnormal responses to both forms of examination, but after the oedema fluid absorbed 63% of cases retained abnormal static profiles whereas 81% recorded defects on Amsler charting. Disturbances of retinal function were most apparent on static perimetry testing if the meridian studied corresponded to that intersecting the site at which the focal breakdown of the choroidoretinal barrier had developed and the fovea. The incidence of retinal changes was found to be greater in patients where the oedema resolved slowly.
