Digital Retinal Imaging & OCT Scans at Hartsdale Family Eyecare
This is very important in assisting Dr. Schwartz to detect and measure any changes to your retina each time you get your eyes examined, as many eye conditions, such as glaucoma, diabetic retinopathy and macular degeneration are diagnosed by detecting changes over time.
Digital Retinal Imaging
Digital Retinal Imaging allows Dr Schwartz to evaluate the health of the back of your eye, the retina. It is critical to confirm the health of the retina, optic nerve and other retinal structures. The digital camera snaps a high-resolution digital picture of your retina. This picture clearly shows the health of your eyes and is used as a baseline to track any changes in your eyes in future eye examinations.
The advantages of digital imaging include:
- Quick, safe, non-invasive and painless
- Provides detailed images of your retina and sub-surface of your eyes
- Provides instant, direct imaging of the form and structure of eye tissue
- Image resolution is extremely high quality
- Uses eye-safe near-infra-red light
- No patient prep required
Optos Daytona Optomap
We are proud to introduce the latest cutting-edge technology in retinal imaging, the Optos Daytona Optomap.
Daytona retinal scan technology is now available at Hartsdale Family Eyecare. This amazing device allows your eye doctor to see retinal, optic nerve and cornea structures not visible through regular exam methods by using light to provide a high-resolution scan meant to pick up early signs of structural change or disease without needing dilation!
Often, the Optomap scan can be done without dilation.
Precise Diagnosis of Diabetes & Eye Disease
Fundus photography uses a specialized, sophisticated digital camera with powerful lenses that focus on the ocular structures of your inner eye. Your fundus is found at the back of your eyeball, which is where your retina is located. A classic fundus photo will show your optic nerve, main retinal blood vessels and macula. These images are used to record and diagnose many eye conditions, including inspecting closely for the effects of diabetes.
At Hartsdale Family Eyecare, our office is equipped with Canon’s Retinal Camera with advanced fundus photography. Dr. Arlene Schwartz, our professional optometrist, is skilled and experienced in recording and analyzing these pictures as a part of our comprehensive eye exams. We will document the images of your fundus and compare them during follow-up visits to our Hartsdale, NY, office. This is a highly effective way to detect changes in your eye health, especially diabetic eye conditions, as well as pay attention to retinal disease, macular holes, macular degeneration and retinal detachment or tears.
How does fundus photography work?
Dilating eye drops will first be placed in your eyes, as light rays from the fundus camera enter your eye through the pupil. After the drops take effect, we will ask you to sit at our compact Canon camera, resting on the chin rest with your forehead against the bar. Once we align and focus the camera, you’ll see a quick flash of light, which generates the fundus photograph.
What eye conditions can be detected with fundus photography?
A fundus photo shows our Scarsdale eye doctors a comprehensive, detailed view of your retina. By comparing images from visit to visit, any changes in your retinal health will be noticed efficiently. In particular, Dr. Schwartz uses fundus photography to keep watch on the signs of diabetes.
Recorded fundus pictures are ideal for tracking the progression of diabetic retinopathy, in which uncontrolled diabetes damages the retina, or macular swelling (macular edema). We will also pay attention to the effects of glaucoma on the optic nerve. In comparison to direct eye examinations, fundus photography makes many of the ocular symptoms caused by diabetes easier to visualize.
Optical Coherence Tomography (OCT)
An Optical Coherence Tomography scan (commonly referred to as an OCT scan) is the latest advancement in imaging technology. Similar to ultrasound, this diagnostic technique employs light rather than sound waves to achieve higher resolution pictures of the structural layers of the back of the eye.
A scanning laser used to analyze the layers of the retina and optic nerve for any signs of eye disease, similar to an CT scan of the eye. It works using light without radiation, and is essential for early diagnosis of glaucoma, macular degeneration and diabetic retinal disease.
These detailed images are revolutionizing early detection and treatment of eye conditions such as wet and dry age-related macular degeneration, glaucoma, retinal detachment and diabetic retinopathy.
An OCT scan is a noninvasive, painless test. It is performed in about 10 minutes right in our office. Feel free to contact our office to inquire about an OCT at your next appointment.
Corneal topography, also known as photokeratoscopy or videokeratography, is a non-invasive medical imaging technique for mapping the surface curvature of the cornea, the outer structure of the eye. Since the cornea is normally responsible for some 70% of the eye's refractive power, its topography is of critical importance in determining the quality of vision.
The three-dimensional map is therefore a valuable aid to Dr. Schwartz in the diagnosis and treatment of a number of conditions such as as keratoconus and other corneal disease. It is also very important for the fitting of special contact lenses and orthokeratology or VST (Vision Shaping Treatment). Corneal topography can also assist in planning refractive surgery such as LASIK and evaluation of its results.
The shape of the cornea is important for any contact lens fittings done, especially when fitting scleral lenses for corneal diseases like keratoconus or even severe dry eye.
Visual Field Testing With our Eye Doctor
A visual field test measures how much 'side' vision you have. It is a straightforward test, painless, and does not involve eye drops. Essentially lights are flashed on, and you have to press a button whenever you see the light. Your head is kept still and you have to place your chin on a chin rest. The lights are bright or dim at different stages of the test. Some of the flashes are purely to check you are concentrating.
Each eye is tested separately and the entire test takes 15-45 minutes.
The Visual Field Test is carried out by a computerized machine, called a Humphrey Visual Field Analyzer. For each test you have to look at a central point then press a buzzer each time you see the light.
We now have a Matrix Visual Field Analyzer. This allows us to more quickly screen and test for glaucoma and other neurological illnesses.
TelScreen - Anterior Segment Camera
The anterior segment camera is an optometric device that is used to examine the front surface and anterior portion of the eye helps to detect and track the progression of external diseases of the eyelids, blepharitis, styes, corneal diseases, conjunctival diseases and cataracts.
It is a very important tool for documenting diseases of the eye as a baseline to watch for progression or changes associated with the conjuctiva, chronic lid conditions or other conditions of the conjuctiva and cornea such as pterygiums. It is also helpful when fitting specialty contact lenses, scleral lenses, gas permeable and hybrid lenses for the treatment of various corneal diseases such as kerataconus.
Describing the convenience and opportunities for patient education afforded by the anterior segment camera, Dr. Schwartz comments, “Since I'm already looking at the patient's eye with the slit lamp, it is very easy to take a picture at the same time, making it easy and comfortable. In addition, the photo comes up on a large monitor when the person is still sitting in the exam chair so it is easy to explain to the patient what I am looking at. This is also true with contact lenses. With specialty contact lenses, it is easy to explain the fit and reason for larger scleral lenses.”
Dr. Schwartz recommends that the anterior segment camera be used for patients that need to see what is going on with conditions such as blepharitis, when lid hygiene is important, in order to demonstrate to the patient how lid hygiene and lid scrubs will help the condition. This is also true with conditions such as nevi and pterygiums, which often need to be monitored for progress, making a baseline photo a valuable tool.

The BlephEx™ treatment is a precise, safe and effective way to clean and exfoliate your eyelids and eyelashes to relieve symptoms of blepharitis.
What is blepharitis?
Blepharitis is an inflammatory disease affecting the eyelids and eyelashes and causes a buildup of scurf, debris and bacterial toxins at the base of the eyelashes. This is known as anterior blepharitis. The inflammation caused by anterior blepharitis causes the eyelid tissue where the meibomian tear glands reside to become thick and swollen, preventing healthy oils from being released into the tears. This is known as posterior blepharitis or meibomian gland dysfunction (MGD). This causes significant symptoms of burning, itching, dry eyes and general eye discomfort. MGD traps bacterial toxins at the lid margin causing more anterior blepharitis and a continous vicious cycle of inflammation is formed.
What are the symptoms of blepharitis?
- Itching or scratchy eyes
- Foreign body sensationTearing
- Dry eyes
- Eye rubbing
What is the most effective way to treat blepharitis?
With the new BlephEx™ instrument, we can now effectively clean and exfoliate scurf, debris and inflammatory toxins from the eyelids and eyelashes to disrupt the vicious inflammatory cycle established with uncontrolled blepharitis!
What can I expect from treatment with BlephEx™?
It generally takes about fifteen minutes to perform the BlephEx™ procedure on all of your eyelid margins. The procedure is painless but you will feel a tickle or itch during the treatment! Dr. Schwartz takes her time and makes sure you are comfortable and most of the scurf and debris is exfoliated from all of your eyelid margins. You can expect the treatment to last for several months. Some patients may need treatment once a year while others with aggressive blepharitis may need several treatments in a year.
If you have any of the symptoms of blepharitis, schedule a BlephEx™ treatment today
