Fluorescein Angiography  
Fluorescein angiography is a diagnostic procedure that uses a water-soluble dye (fluorescein) and a special camera to take pictures of the retina.  The procedure allows the physician to make a thorough diagnosis of any retinal abnormality.
Fluorescein is injected into a vein in the arm.  The dye circulates throughout the entire body.  As the blood passes through the retina a camera with a blue flash takes a series of pictures of the retina.  If the retinal blood vessels are damaged, the dye may leak into the retina.  The dye will also reveal if there is damage to the lining under the retina, as well as the growth of abnormal new vessels.
Fluorescein angiography is used in patients with diabetes, macular degeneration, and in any other case where the physician suspects an abnormality in the back of the eye.

Optical Coherence Tomography

Optical Coherence Tomography (OCT) is a laser-based instrument that allows the physician the ability to qualitatively measure structures in the retina.  It analyzes the retinal nerve fiber layer as well as the thickness of the macula and optic nerve head allowing for early treatment of diabetic macular edema, macular holes, and age-related macular edema.

Pneumatic Retinopexy/Cryotherapy
Pneumatic retinopexy/cryotherapy is performed to repair retinal tears and detachments.  First, cryotherapy (freezing) is performed to seal the retinal tear.  The physician then injects a gas bubble into the vitreous cavity.  The patient is instructed to keep their head in a specific position so the gas bubble pushes the retina against the eye wall. 

Retinal Lasers
Panretinal photocoagulation is a laser used to treat proliferative diabetic retinopathy.  It is performed to destroy all the areas of the retina where new blood vessels (neovascularization) have closed off.  These areas of the retina stop producing neovascularization.  The neovascularization that is already present usually decreases and disappears.  Panretinal photocoagulation does not improve vision. It is done to stop neovascularization to prevent severe vision loss.  The laser spots are place in the peripheral retina.

Focal photocoagulation is a laser used to treat background diabetic retinopathy.  It is performed in specific areas of the retina to stop leaking.  These areas are pinpointed by fluorescein angiography.  This type of laser is does not improve vision.  It is a means of preventing the further loss of vision.
Retinal lasers are also used to seal off retinal tears or holes to prevent retinal detachments.  It does not improve vision, but prevents severe vision loss that may occur with a retinal detachment.

Lucentis, Avastin, and Triessence Injection
Intravitreal injections are needed for many eye disorders including Macular Degeneration, Diabetic Retinopathy, and Retinal Vein Occlusions.  The eye is prepped with a Betadine solution to prevent any type of infection that can occur with an injection.  The eye is anesthetized as well to prevent any eye discomfort that may occur with the injection. After receiving an injection of Avastin, Lucentis or Triessence for your retinal condition, you may notice string-like strands floating in your eye. These are called "floaters" and usually disappear within 7 to 10 days. Your vision may be blurry for the first 3-5 days post injection. Your eye may be red for 2-3 weeks post injection. If any pain, headaches, or loss of vision occurs prior to the next injection, the physician needs to be notified immediately as this may be a sign of infection.

Ozurdex Implant
The Ozurdex is a steroid implant that is FDA approved for retinal swelling or edema secondary to retinal venous occlusion. The Steroid is biodegradable and lasts approximately 4-6 months within the eye where it is slowly dissolved.  The eye is prepped with Betadine solution to prevent any type of infection that can occur with an injection.  The eye is anesthetized as well to prevent any eye discomfort that may occur with the injection of this implant. After receiving the Ozurdex implant, you may notice a large floater which is the implant itself. Your vision may be blurry for 3-5 days post injection and may be red for 2-3 weeks post injection.
