Abstract

Purpose: : To compare images made with a new FD-OCT device, mounted on a slitlamp with images of the same region made with OCT Stratus (Zeiss), and 3D OCT-1000 (Topcon).

Methods: : Images were made in selected patients, with representative macular pathology with a newly developed FD OCT scanning device integrated into a common slitlamp (figure 1). OCT characteristics: central wavelength 830 nm, bandwidth 30 nm, resolution in tissue 8 micron, scanning speed 1000 a-scan per sec, one b-scan in 0.2 sec, scandepth 2 mm. Scans are made through a handheld lens (Volk 60 D), while simultaneously the (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).In the same patients line scans were made with the OCT Stratus and 3D volumes scans were made with the 3D OCT-1000. Scans made at approximately the same location were subjectively compared with respect to quality of the images.

Results: : With the new device scans could be made without difficulty in all patients with a reasonably clear retinal image on slitlamp examination. Examples of scans made with the 3 devices of patients are shown. (see figure 2 to 5). The quality of the scans made with the new device is better than the OCT Stratus, and slighly less than the 3D OCT-1000.

Conclusions: : Quality of the scans made with the new device compare favourably with TD-OCT images (OCTStratus, Zeiss), and are slightly less than scans made with dedicated FD-OCT systems. The ease of use and the instanteneous availablity of results of OCT examination, during a regular clinical examination, could be very usefull in daily practice.
