Infrared imaging of central serous chorioretinopathy, A follow‐up

Abstract

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.

Visualization of cystoid macular oedema using a scanning laser ophthalmoscope in the retro‐mode

“…Remky et al. successfully visualized the extent of serous retinal detachment in eyes with central serous chorioretinopathy 27 . In eyes with CMO, each cystoid space can reportedly be visualized non‐invasively in a monochromatic image obtained with SLO in the indirect mode with an infrared laser 9,10 .…”

Detection of shallow detachments in central serous chorioretinopathy

“…Specific enhancement of the serous neuroretinal detachment may be achieved, however, by fundus imaging using infrared laser scanning in the indirect mode (Remky et al 1998). The relative thresholds for the detection of serous detachments by this method and optical coherence tomography have not been compared.…”

Drusen detection in retro-mode imaging by a scanning laser ophthalmoscope

“…Indirect mode has demonstrated enhanced imaging of macular drusen in a small number of patients (Manivannan et al. 1994; Hartnett & Elsner 1996), an area of elevation in choroidal neovascularization (Hartnett & Elsner 1996), easy detection of detachment of the neuroretina in central serous retinopathy (Remky et al. 1998) and the emphasized appearance of borders in cystoid macular oedema (Remky et al.…”
