Retina is a small sub-specialty in medicine requiring their physicians additional study to achieve. Their practice specialty requires an approximate population of 200,000 for every specialist. The problem with Florida, as with most of the United States, is that most of is it is spread out over many rural areas. This creates a problem in general for rural patients. It is worse for rural patients needing retina specialists since they are limited in number and often found only in bigger cities. For this reason, Central Florida Retina has strategically expanded over the years to cover all of Central Florida to better serve its Florida patients. Over the decades, the number of physicians in the practice typically fluctuates between four and six physicians, as senior doctors eventually retire and new doctors join this long respected practice. It takes ten additional years of study after college to become a retina specialist. This includes four years of medical school, one year of internship, three years of residency and two years of retinal fellowship.
