• Dr. Mark Hornfeld Explains How the OCT Machine Works

    An Optical Coherence Tomography (OCT) machine is helpful for diagnostic purposes. Ophthalmologists can view a cross-section image of the optic nerve and the macula, which is the center of the retina. This provides valuable information for diagnosing various eye diseases and for monitoring the progression of treatment of an eye condition.

    Watch this video to hear Dr. Mark Hornfeld explain how he uses his OCT machine at his NYC ophthalmology practice. You’ll hear him explain the benefits of this cutting-edge technology. For example, patient safety is preserved because no radiation is needed. Plus, the images are available right away.

  • Common Eye Health Emergencies

    Scheduling exams with an ophthalmologist at least every six months allows for the early detection of vision problems, such as glaucoma and cataracts. However, certain circumstances call for an emergency visit to the ophthalmologist’s office . If you experience any abrupt changes in your vision, for example, it could signal a serious eye health problem. The following issues constitute eye health emergencies:

    Common Eye Health Emergencies

    Eye Injury

    If you suffer from persistent or significant eye pain, redness of the eye, and decreased vision, you could have an eye injury. Sometimes, eye injuries are easily detected. For example, you could suffer trauma to the facial area if you’re involved in a vehicular accident. In other cases, they are not quite so obvious, such as when small particles of abrasive material enter your eye and scratch the cornea. If you experience an eye injury, avoid rubbing the eye. Instead, have someone take you to the ophthalmologist’s office right away.

    Vision Loss

    Sudden vision loss is a possible complication of an eye injury; however, it may also indicate other eye health problems. One of the possible conditions it may indicate is retinal detachment, which occurs when the tissue located at the back of the eye becomes separated from the blood vessels. These blood vessels are necessary to provide the retina with nutrients and oxygen. Another symptom of retinal detachment is flashes of light in your vision . If there is a possibility you’re experiencing retinal detachment, time is of the essence. The sooner an ophthalmologist can treat you, the better your chances are of recovering your vision.

    Eye Inflammation

    Falling asleep while wearing contact lenses is a common problem for many. Unfortunately, it can sometimes lead to a corneal ulcer, which is an open sore on the cornea often caused by an infection or severely dry eyes. If you wake up with painful, red eyes that are sensitive to the light, see an ophthalmologist to reduce your risk of corneal scarring.

    If you experience abrupt changes in your vision or other significant eye health concerns, we encourage you to call the office of Dr. Mark Hornfeld , ophthalmologist. Dr. Hornfeld’s ophthalmology practice in NYC offers a range of procedures to correct vision problems using cutting-edge medical technology. If you have any questions, give us a call at (646) 502-4142.

  • What Is 20/20 Vision?

    Spectacles on an eye chart

    Ophthalmologists define 20/20 vision as the ability to see objects clearly from 20 feet away. This measurement refers to the sharpness or clarity of your vision, which is called normal visual acuity. However, it’s important to note that there are other aspects to your vision that are not factored into this particular measurement. For example, having 20/20 vision does not necessarily equal having great eye coordination, depth perception, peripheral vision, color vision, or focus. These factors can also affect how well you see.

    When you schedule an exam with an ophthalmologist, the doctor will consider all of these factors when evaluating your vision. You might choose to correct your vision with contact lenses or glasses. Or, you could ask your ophthalmologist about vision correction surgeries, such as LASIK surgery.

    If you wish to schedule a consultation for LASIK surgery or other eye care procedures, please call the office of Dr. Mark Hornfeld at (646) 502-4142. Dr. Hornfeld’s NYC ophthalmology practice offers a wide range of services, including cataract surgery.

  • A Look at the Link between Nutrition and Cataracts

    Cataracts, which are quite prevalent, are a leading cause of vision loss. They occur due to damage to the proteins found in the lens of the eye. Certain factors can increase your risk of developing cataracts, such as family history, age, and sunlight exposure. However, researchers have discovered that nutrition also plays a critical role in the prevention of cataracts . At your next ophthalmologist appointment, you can talk to the doctor about including the following nutrients in your diet to help prevent cataracts.

    A Look at the Link between Nutrition and Cataracts

    Carotenoids

    Lutein and zeaxanthin are carotenoids that your eyes need for healthy vision. Studies have shown that including plenty of these carotenoids in your diet may offer some protection against cataracts. In fact, according to the American Optometric Association , the Nurses’ Health Study demonstrated a link between decreased cataract development and an intake of six milligrams of these nutrients daily. You can talk to your ophthalmologist about taking lutein and zeaxanthin in a supplement, or you might prefer to include more food sources of these carotenoids in your diet. Some great food sources of lutein and zeaxanthin are kale, collard greens, spinach, turnip greens, and broccoli.

    Antioxidants

    In addition to getting more lutein and zeaxanthin in your diet, you might consider including more sources of antioxidants, such as vitamins C and E. Research has demonstrated an association between a delayed progression of cataract development and the consumption of these nutrients. They may also help prevent cataracts from forming in the first place. You could take a vitamin pill or consume foods that contain these antioxidants, such as papaya, cantaloupe, and kiwi for vitamin C, and almonds, peanuts, and sunflower seeds for vitamin E.

    Although following a healthy diet will help reduce your risk of cataracts, they can occur due to factors beyond your control. Dr. Mark Hornfeld offers advanced treatment for cataracts, including intraocular lens implants (IOLs) to restore your vision.
