To present results of images of the retinal periphery with a new FD-OCT device, integrated into a slitlamp, during direct observation of the area of interest.
Patients with peripheral laser coagulations, seen in the outpatient clinic of the Academic Medical Center, were scanned with a newly developed OCT scanning device, integrated into a common slitlamp (figure 1). The OCT is a Fourier Domain OCT system (SLD light source, central wavelength 830 nm, bandwidth 30 nm, 1024 pixel CCD camera, resolution in tissue 8 micron, scan speed 5k A-scans per second, 1024 A-scans per B-scan). Scans are made through a 3-mirror lens (Volk), while simultaneously the peripheral lesion in the retina can be observed with the slitlamp. A color fundus photography of the observed area is made at the same time (Topcon camera DC1, resolution = 3.24 Mp).
With the new device scans could be made of the retina anterior to the equator in all patients with a reasonably clear retinal image on slitlamp examination. Examples of scans are shown in figure 1 to 6.
Images of retinal lesions anterior to the equator can be made with a new slitlamp integrated FD-OCT, and could be useful in patients with peripheral pathology.
