Opthamologists are constantly using technology to gain a better understanding of what diseases are plaguing the eye. If you have ever been to the eye doctors before for a procedure then you have probably had pictures taken of your eyes. Ocular photography or external ocular photography serves a crucial purpose in diagnosing and identifying eye diseases and problems. This article will give an overview of how external ocular works and the capabilities it has to help patients and medical professionals.

Equipment

There is a variety of equipment that can be used during eye exams to diagnose a wide range of problems within the eye. Some basic and common pieces of equipment that you may have seen or heard of before include a Phoropter, Retinal Camera, and Slit Lamp.

Phoropter – also spelled Phoroptor is one of the most common pieces of equipment people think about when they imagine an eye doctor’s office. A Phoropter is used to test an individual’s vision and identify if they may suffer from something like nearsightedness, farsightedness, or astigmatism. The Phoropter gives the doctor the ability to adjust the intensity of a lens on the fly allowing them to analyze how your vision is corrected through the different intensities. The patient plays a integral part in this because they ultimately decide what lens they think works best for their vision by answering questions from the eye doctor as they change the lens intensity.

Retinal Camera – A Retinal Camera is used to view the back of your eyes including the retina and optic disk. The optic disk holds the optic nerve which is responsible for sending information from your eye to your brain. A Retinal Camera can help your opthamologist identify eye disease such as macular degeneration.

Slit Lamp – A Slit Lamp is another more common piece of equipment that people may be familiar with. A Slit Lamp is used to look at multiple parts of your eye at once. The Slit Lamp is used to view the sclera, the cornea, and the lens of your eye. The Slit Lamp aims a high-powered, bright beam at your eye that scans the previously listed areas of your eye. Preparation for using a Slit Lamp can include dilating your pupils and inserting yellow colored eye drops into your eye to see potential problems in the front of your eye.
