Indirect & Direct Ophthalmoscopy
The indirect Ophthalmoscope is light source attached to a head band which when used with an indirect lens allows Dr. Hodgson to examine the lens for opacities/cataracts and also to examine the retina and optic disc, which is the neurosensory portion of the eye, most responsible for your pet’s vision.
The direct ophthalmoscope is the smaller hand held popsicle looking tool that most human physicians use to examine the optic disc in humans. This tool is used in veterinary ophthalmology with sometimes great difficulty compared to the indirect ophthalmoscope as it utilizes higher magnification in a mostly moving target….giving the doctor fleeting glimpses or fragments of a larger picture that must be stitched together in the ophthalmologists mind at the conclusion of the exam.
