Corneal Mapping in Manhattan, NY

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 the examining ophthalmologist or optometrist and can assist in the diagnosis and treatment of a number of conditions; in planning refractive surgery such as LASIK and evaluation of its results; or in assessing the fit of contact lenses. A development of keratoscopy, corneal topography extends the measurement range from the four points a few millimeters apart that is offered by keratometry to a grid of thousands of points covering the entire cornea. The procedure is carried out in seconds and is completely painless.

Digital Retinal Imaging & OCT Scans

We use cutting-edge digital imaging technology to assess your eyes. Many eye diseases, if detected at an early stage, can be treated successfully without total loss of vision. Your retinal Images will be stored electronically. This gives the eye doctor a permanent record of the condition and state of your retina.

This is very important in assisting Dr. Schlussel and his eye care staff in NYC 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.

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

Digital Retinal Imaging

Digital Retinal Imaging allows your eye doctor 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.

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.

With an OCT scan, eye doctors are provided with color-coded, cross-sectional images of the retina. 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.

The Goldman Applanation Tonometer

In our office we only use the "puff-less" Goldman Tonometry method to determine the intraocular pressure (IOP), the fluid pressure inside the eye which ias an important test in the evaluation of patients at risk from glaucoma. Learn More.

Visual Field Testing

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. Your optometrist may ask only for a driving licence visual field test, which takes 5-10 minutes. If you have just asked for a driving test or the clinic doctor advised you have one, you will be informed of the result by the clinic doctor, in writing, in a few weeks.

Normally the test is carried out by a computerised machine, called a Humphrey. Occasionally the manual test has to be used, a Goldman. For each test you have to look at a central point then press a buzzer each time you see the light.

OPTOS Retinal Exam

Dr. Schlussel's Office in Manhattan have top of the line Optos equipment on site in order to provide the best possible patient care. Learn More.

BlephEx

BlephExThe 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 sensation
  • Tearing
  • Crusting
  • Redness/Inflammation
  • Mattering
  • 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. Schlussel takes his 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!

Meibography:

Meibomian gland evaluations. During the slit lamp examination, Our doctors use an instrument that evaluates the meibomian gland function and helps determine the number of functioning glands. Expression of the glands determines whether the patient expresses oil on a full blink or if the gland expresses a thick non-oily substance. The ocular surface relies on the oil in the tears to keep it wet and smooth for the blink.

Meibography. Our eye doctors will determine if all the patient’s meibomian glands are functioning by using Meibox, a meibography imaging test which illuminates the glands with a non-invasive Infra-red light. As the meibomian glands clog, they can become damaged. The longer they are clogged, the more damage occurs and eventually, the gland structure can become atrophied. We only have the glands we are born with, once they are gone; they are gone!
