Abstract
BACKGROUND: Infrared (IR) imaging improved by using scanning laser ophthalmoscopy. The greater penetration of infrared light compared with visible wavelengths permits better visualization of subretinal structures such as drusen, hyperpigmentations and choroidal new vessels. Furthermore, using the indirect mode of the instrument to detect laterally scattered light, drusen and shallow detachments of the neuroretina can easily be visualized as prominent structures. In this study we investigated the potential use of non-invasive infrared imaging in follow-up examination of patients with central serous chorioretinopathy (CSCR). METHODS: All patients with an acute CSCR underwent fluorescein angiographic studies (488 nm) and infrared imaging (788 nm) in indirect mode using a scanning laser ophthalmoscope (SLO 101; Rodenstock) at baseline and follow-up after 3-5 weeks. RESULTS: The detachment of the neuroretina could easily be visualized by infrared imaging as prominent, oval-shaped structures. The height varied corresponding to the clinical course, whereas the extent showed no relation to the change in symptoms. CONCLUSION: IR-imaging is a quick, non-invasive tool which may efficiently be used in chorioretinal diseases. In CSCR patients it provides an adjunct in clinical follow-up by monitoring the course of the disease and the effect of treatment concepts.
