Fundus Autofluorescence (FAF):
Our practice has the Heidelberg Spectralis HRA with FAF capability. FAF is useful in the early diagnosis of macular telangiectasia type 2, a condition sometimes misdiagnosed for age-related macular degeneration. FAF is also useful for screening for hydroxychloroquine (plaquenil) toxicity. FAF is also useful in better demonstrating the changes that occur in dry age-related macular degeneration and in the diagnosis and monitoring of treatment for posterior uveitis.

Spectral Domain Optical Coherence Tomography (SD-OCT):
Our practice has the Heidelberg Spectralis OCT 2, the latest SD-OCT that can take 70,000 scans of the retina per second and process these to produce a cross-section of the retina. An invaluable tool for the diagnosis and evaluation of treatment response in wet age-related macular degeneration, diabetic macular edema, macular edema related to retinal vein occlusion, following cataract surgery or with uveitis as well as macular holes and epiretinal membranes. The Spectralis OCT 2 can take pictures of the exact same area each visit to allow direct comparisons with the prior visit.
Ultra-wide field infrared photography and angiography:
Our practice has the Heidelberg Spectralis Ultrawide-Field Infrared and Angiography camera. With this equipment we can study regions of the peripheral retina following injection of fluorescein and/or indocyanine green dyes through a vein. This shows abnormal vessels in the retina, patterns of vessels in a tumor or areas where there is poor circulation in the peripheral retina. A useful tool for patients with diabetic retinopathy, retinal vein occlusion, peripheral retinal neovascularization, peripheral posterior segment tumors, retinal vasculitis, posterior uveitis etc.
