There are many different types of procedures performed in our office. Here are a few examples and explanations of our most commonly performed procedures:
Fluorescein Angiograms
Intravenous Fluorescein angiography is a technique for examining the circulation of the retina and choroid using a fluorescent dye and a specialized camera. An injection of sodium fluorescein into the bloodstream is preformed, and then an angiogram is obtained by photographing the fluorescence emitted after illumination of the retina. The dye highlights every part of the vascular system in the eye so that the physician can evaluate the integrity of the vessels in the eye. Possible side effects include bright yellow urine for 48 hours, slightly jaundiced skin for about 24 hours and slight nausea lasting several minutes following the procedure.
B-scan/A-scan
Ultrasound of the eye, preformed over or under the eyelid. Anesthetic is applied so that the patient is comfortable. Ultrasounds are sometimes preformed when the physician is unable to see into the eye or for diagnostic measurement purposes.
OCT/Optical Coherence Topography
A topographical scan of the inside of the eye is performed for numerous reasons. The scan uses infrared lasers to acquire an image of surface area and thickness. This test can be performed on un-dilated patients and takes only a few seconds to complete. This machine has drastically reduced the need for more extensive testing used in the past by retina physicians.
Intravitreal Injections
Injections into the eye have become a wide spread treatment option among physicians. Less invasive than laser for certain diagnosis, physicians will opt to inject a patient for maximum visual outcome. The eye is anesthetized, sterilized and then injected. Patients can expect no pain during the procedure. Following the procedure, possible side effects may include, blurred vision, black spots in the vision lasting several hours to several days, slight decrease in visual acuity and redness on the surface of the eye.

Laser-Photocoagulation
Laser cauterizes ocular blood vessels and retinal tissue and are widely used to treat numerous eye conditions and diseases. Depending on the amount of laser necessary, patients may receive either topical anesthetic or a localized anesthetic block as to maximize the patients comfort level. Side effects may include blurred vision and some mild soreness. Most patients return to work the following day.
