AimTo investigate treatment-related pain and the accuracy of navigated laser photocoagulation in the treatment of clinically significant macular edema.MethodsFocal laser treatment of diabetic macular edema in 54 consecutive patients was digitally planned on fundus images and performed using the navigated laser photocoagulation system Navilas® (OD-OS GmbH, Teltow, Germany). Treatment-related pain was quantified on a visual analog scale directly after treatment and compared with a matched control group who received conventional laser treatment (n = 46). In addition, for Navilas-treated patients, the accuracy of spot placement on color images was analyzed 1 month after treatment.ResultsIn total, 5423 laser spots (mean 100 per eye) were analyzed. With navigated treatment, 90% of laser spots were visible on color images, of which 96% were within 100 μm from the target. Eighty percent of the laser spots were placed and visible within the 100 μm target on an intention-to-treat basis for color imaging. Optical coherence topography confirmed that laser effects were limited to the outer retina. Treatment-related pain following navigated laser photocoagulation was significantly lower than that of conventional laser treatment (1.6 vs 4.4 on a visual analog scale, P < 0.001).ConclusionNavigated laser effects could be visualized to a high percentage on post-treatment color images, and their location showed a high concordance to targeted areas. Patients reported that treatment-related pain following Navilas laser photocoagulation was significantly lower than pain following conventional laser treatment.
After NAVILAS treatment for DME a high percentage of laser effects could be visualized on post-treatment color images and the location showed high concordance with the preplanning target.
We reported a case of unusual intraocular Loa loa in a 27-year-old patient who presented with painful red eye. Biomicroscopy revealed a living and active adult worm in the anterior chamber of the right eye. After surgical extraction under local anesthesia, parasitological identification confirmed L. loa filariasis.
Purpose To investigate accuracy of a navigating laser photo‐coagulator in clinically significant macular edema.
Methods Focal laser in 20 patients was digitally planned on fundus images and performed with navigation using Navilas® (OD‐OS GmbH, Teltow, Germany). On color images, OCT and autofluorescence we analyzed 784 laser spots (mean 39 per eye) at one week follow‐up and determined accuracy of spot placement using an image flicker method.
Results 76% of lesions were visible on color images, 95% were within 100 µm from the planned target. OCT confirmed that laser effects were limited to the outer retina.
Conclusion Navilas® laser effects were visualized to high percentage on post‐treatment images, location showed high concordance to preplanning.
