Digital Photography

Some of the photos were obtained with a Canon Powershot Digital Elph (we recommend the models with image stabilization) compact digital camera through the ocular of the slit lamp biomicroscope or operating microscope. The fundus photographs were obtained from a digital photography system made by OIS.
