Special Diagnostic Vision Testing
Providing you Quality Eye Care.
Special Diagnostic Vision Testing
At Real Eyes Optometry, we provide special diagnostic vision testing in addition to typical eye exams. We use digital retinal photography, a visual field analyzer as well as OCT scanning. Continue reading for more details on each process.
Special Diagnostic Vision Testing: Digital Retinal Photography
The retina is located in the back part of your eye, the object your eyes are looking at is imaged at the retina (similar to the film in a camera). Many eye diseases can develop without warning and can even get worse without any symptoms or changes in your vision. A thorough exam of the retina can detect diseases such as macular degeneration, glaucoma, retinal tears or detachments, and vessel occlusions, as well as other systemic problems such as diabetes, high cholesterol, high blood pressure, thyroid issues, multiple sclerosis and drug abuse.
Digital Retinal Photography provides:
- Photo-documentation to confirm a healthy eye or detect the presence of disease.
- An overview of the retina, giving your Optometrist a more detailed view with the ability to zoom in on certain structures.
- The opportunity for the patient to view and discuss the images of their eye with an Optometrist at the time of their exam to better understand how eyes work and how the eyes are affected by certain lifestyle choices.
- A permanent record for the patients medical file, enabling your Optometrist to make important comparisons if potential changes are detected during future examinations.
Special Diagnostic Vision Testing: Visual Field Analyzer
A visual field machine is used to assess and map out the patient’s peripheral vision in each eye. This helps in the detection of various ocular and neurological abnormalities such as stroke, glaucoma, retinal damage, retinal atrophy and brain/ocular tumors. A patient’s peripheral vision (aka Visual field) is very important when driving any type of vehicle.
At Real Eyes Optometry, we use a screening method via in-office testing to assess all patient’s peripheral vision ability. If any defects are detected via that screening or any retinal issues are observed via ocular assessment, we have a more extensive visual field analyzer which is used to provide the doctors with a more detailed representation of the patients peripheral vision. The machine will measure how large each eye’s peripheral field is, how sensitive the peripheral field is, if there are any defects within the peripheral field, and how reliable the visual field test was.
This instrument is a standard test to monitor patients with glaucoma because it can help the doctor determine if the glaucoma is progressing and how effective the prescribed treatment is in preserving the peripheral vision in each eye.
Special Diagnostic Vision Testing: Ocular Coherence Tomography
An OCT scan is an imaging tool is another type of special diagnostic vision testing similar to an ultrasound. It uses a scanning laser to analyze layers of the retina, optic nerve, and macula. This allows for early detection of certain ocular diseases such as glaucoma and macular degeneration as well as multiple other retinal issues (tissue at the back part of the eye). It is also used to determine if certain medications such as Plaquinel and Hydroxychloroquine are causing permanent damage to the retinal tissues.
