Visual Fields - Many conditions and diseases reduce ones peripheral vision.

We use computer assisted automated perimetry to accurately assess our patients' peripheral vision and to monitor the progression of their disease. The test uses different strategies to test for specific disease processes. This test involves focusing on a fixation target while small spots of light of varying intensity flash in the peripheral visual field. The computer records the responses of the patient and through statistical analysis, helps determine the level of vision impairment. This recently developed and refined procedure has greatly helped us manage a number of conditions, especially glaucoma

Corneal Topography - Corneal Topography is one of the most rapidly developing specialty tests in eye care.

The cornea is the clear covering of the eye and is responsible for the majority of the focusing power of the eye.

Due in part to the progression of excimer laser treatments for corneal irregularities and refractive errors, it became necessary to develop a means of accurately measuring the shape of the cornea.

This instrument, through computer aided graphics, plots a topographical map of the cornea to highlight irregularities, distortions, astigmatism, and other corneal anomalies.

Flourescein Angiography - We use flourescein angiography to aid in the diagnosis and treatment of retinal disorders such as diabetic retinopathy and macular degeneration.

Our Digital Flourescein Angiography provides our doctors with high-resolution, brilliantly clear pictures that are available for the doctors to view immediately. These pictures will highlight any area of bleeding or leakage in the retinal blood vessels. The test is accomplished by injecting a small amount of dye into a vein in the arm and taking a series of photographs as the dye circulates through the eye. The doctor can then make specific diagnostic and treatment plans using the photos as a map to identify areas needing treatment.

 HRT (Heidelberg Retinal Tomography) - The HRT is used to monitor changes in the optic nerve for conditions such as Glaucoma and other optic nerve disorders. 

This diagnostic equipment aids in the early diagnosis and treatment of glaucoma and ocular hypertension.  Any changes in the optic nerve due to high intraocular pressure of the eye will be depicted with detail in this imaging.

The HRT is a non-invasive test that captures images while the patient is comfortably positioned at the instrument.

OCT (Optical Coherence Tomography) - The OCT is used to diagnose Retinal disease such as Age Related Macular Degeneration, Macular Edema and Macular Holes.  

The retina is the nerve layer that lines the back of the eye.  The retina contains special light sensitive cells helping us to see fine details clearly.  

This device captures three-dimensional images of the retina by measuring optical reflections.  These images show swelling or bleeding in the retina and helps to determine which type of treatment is recommended.

The OCT is a non-invasive test that simply takes a picture of the patient’s retina while they are comfortably positioned at the instrument.
