    Cone Photoreceptor Integrity assessed with Adaptive Optics Imaging after Laser-Pointer-Induced Retinal Injury

    Purpose: To examine the three-dimensional foveal cone photoreceptor structure in a patient who had suffered laser pointer induced retinal injury . Methods: Patient underwent standard fundus photography and clinical spectral domain optical coherence tomography (SD-OCT) imaging. High-resolution imaging was performed using an Adaptive Optics -OCT-Scanning Laser Ophthalmoscope (AO-OCT-SLO). Results: AO imaging revealed loss of inner and outer segments of cone photoreceptors while the anterior retinal layers appeared healthy. Analysis of cone topology showed an increase in Voronoi domain area and a less regular hexagonal packing structure closer to the lesion site. Conclusion: Exposure to laser pointer radiation, however brief, can result ...
