Purpose To demonstrate the flexibility and quality of a new SL‐FD‐OCT device, mounted on a slitlamp, in daily clinical practice. Methods Images were made in patients, with different types of macular pathology, and 30 patients with AMD, treated with ranibizumab, with a newly developed FD OCT scanning device integrated into a common slitlamp. Scans were made through a handheld lens (Volk 60 D), while simultaneously the (lesion in the) retina could be observed, with the slitlamp. A color fundus photograph of the observed area was made at the same time (Topcon camera DC1, resolution = 3.24 Mp). For comparison, line scans were made in the same patients with the Stratus‐OCT (Zeiss) and 3D‐volume scans with the 3D‐OCT‐1000(Topcon). Scans made at approximately the same location were subjectively compared with respect to quality of the images. Results With the new device scans, and photographs could be made without difficulty in all patients with a reasonably clear retinal image on slitlamp examination. The quality of the scans made with the new device is better than the Stratus‐OCT,and slighly less than the 3D‐OCT‐100. In 30 patients with exudative AMD, treated with ranibuzumab, conclusions regarding the presence of leakage based on SL‐FD‐OCT images were in concordance with the conclusions based on 3D volumes with the 3D‐OCT‐100(Topcon). Conclusion Quality of the scans made with the new device compare favourably with scans of the Stratus‐OCT (Zeiss), and are slightly less than scans made with the 3D‐OCT‐1000 (Topcon). 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.
