Retina Tests & Procedures



Optical Coherence Tomography (OCT)

OCT is a method for obtaining cross-sectional images of the retina which is both non-invasive and non-contact. High resolution images of the retina are obtained which can detect subtle changes in a variety of disease conditions including age-related macular degeneration, diabetic eye disease, retinal vein occlusion, macular hole, epiretinal membrane, and retinal detachment. The test takes less than a minute to obtain in most cases.

Fluorescein Angiography (FA)

FA is a technique for examining the circulation of the retina using a water soluble fluorescent dye and a specialized camera. Sodium fluorescein is injected into the circulation system through an arm vein, the retina is then illuminated with blue light and pictures are obtained which can detect dynamic changes in blood flow. FA is used to detect changes due to a variety of conditions including age-related macular degeneration, diabetic retinopathy, retinal vein occlusion, hypertensive retinopathy, and central serous retinopathy. This technique does not require or use any ionizing radiation.

Indocyanine Green Angiograpy (ICG)

ICG is a technique similar to FA used for medical diagnostics and digital imaging of ocular blood flow within the eye. ICG angiography images in the infared spectrum of light which is used to image blood vessels located deeper in the retina than detectable by FA. ICG angiography is sometimes combined with FA.

Intravitreal Injections (IVT)

IVT injections are used to deliver medications into the eye to treat a variety of conditions including wet age-related macular degeneration, diabetic retinopathy, retinal vein occlusion, and vitreous bleeding. It is the most common procedure regularly performed in the office. The procedure is safe and requires only topical anesthesia.

Retinal Laser Procedures

Retinal laser procedures are used to treat a variety of conditions in the office. Retina laser is an effective and safe treatment for a wide variety of retinal conditions including diabetic retinopathy, retinal tears and detachments, retinal vein occlusions, and retinal microaneurysms.

Ophthalmic Ultrasound (US)

Ultrasound is a non-invasive, minimal contact procedure that uses sound waves to visualize ocular anatomy. Ultrasound can be used to measure the length of the eye, image through dense cataracts, hemorrhage, or measure the size and dimensions of foreign bodies, tumors, or detect retinal tears or detachments.

Cryotherapy (Cryo)

Cryotherapy is a technique where subzero temperatures are applied to areas of pathology in the retina. These can include retinal or choroidal tumors, retinal tears, or retinal detachments.

Pars Plana Vitrectomy Surgery (PPV)

PPV surgery is the most common type of retinal surgery performed in the United States. PPV is most commonly an outpatient surgical procedure performed in the hospital or ambulatory surgical center setting. Local and conscious anesthesia is required. Most procedures are completed in under one hour and recovery is rapid. PPV surgery is used to treat a variety of retinal conditions including retinal detachments, epiretinal membrane, macular hole, and secondary lens exchange procedures.

Scleral Buckle Surgery (SB)

SB surgery is a surgery performed in the hospital operating room or ambulatory care center primarily to repair retinal detachments. It is most commonly an adjunct procedure combined with pars plana vitrectomy surgery, but in some cases can be a standalone primary surgery. SB surgery involves attaching a small silicone band to support the retina.

Lens Exchange or Replacement Surgery

Lens exchange or replacement surgery is needed in cases where the intraocular lens placed after cataract surgery moves causing blurry vision. This may happen spontaneously over time, suddenly in cases of trauma, or may be a complication of the initial surgery. Lens exchange involves either readjusting the lens in place or removing and replacing it with a new lens. Most patients notice substantial improvement in vision after this surgery.
