  1. Visual Cortex Neuron

    This is a fluorescently tagged primary visual cortex neuron from a light microscope capture of a brain slice preparation.  These data were focus stacked revealing a tremendous amount of detail including the spines.  Focus stacking is common method in confocal microscopy, but many folks do not realize that you can also do it with traditional [...]

  2. Silicone Oil In Anterior Chamber

    This image shows a slit lamp retro-illumination photograph through dilated pupil revealing silicone oil in anterior chamber following retinal re-attachment surgery.  Silicone oil is a commonly used approach for retinal tamponade during surgery in the vitreous or for retinal reattachment surgery.  While the silicone does assist with successful reattachment, often it causes optical complications resulting [...]
