Common Retina Diseases

Your retina is essential to how your eye processes the images you see. The retina is a light-sensitive layer in the back of the eye containing cones and rods that signal your brain to convert light into images. Since the retina is critical to eyesight, it is important to regularly visit an ophthalmologist to monitor your eyes for potential diseases that affect your retina.

When an ophthalmologist examines the retina, he or she will use special eye drops to dilate the pupil. When an eye is dilated, an eye doctor can use a magnifying glass to examine the retina. Diseases that affect the retina include macular degeneration, diabetic retinopathy, macular pucker, retinoblastoma, retinal detachment, onchocerciasis, and retinitis pigmentosa. These diseases can be treated by an ophthalmologist and can be diagnosed and detected with regular visits to the eye doctor.

To best protect your retinas and your vision, regularly visit an ophthalmologist near New York. For comprehensive treatment of macular degeneration and other eye diseases, contact Dr. Mark Hornfeld at (212) 580-8881.

LASIK 101: Eye-Opening Information Every Patient Needs to Know

Have you wished there was a way to permanently fix your eyesight and rid yourself of having to wear corrective glasses or contacts? You likely have heard of LASIK surgery, and know that it is a way to achieve better vision. Just as you would prepare yourself for any surgical procedure, it is important to understand what the surgery is and what it can do. To help you make the decision, check out this overview of LASIK surgery.

How the Surgery Works

LASIK surgery is a two-part procedure. An eye surgeon will first use a laser or blade to create a flap on the top layer of the cornea. This exposes the middle section of the cornea. A second laser is used to reshape the cornea. The way the cornea is reshaped is based on each patient and his or her specific needs. After the reshaping of the cornea, the flap is folded back into place. The incision heals itself over time.

If You Are a Candidate for LASIK

Most adults over the age of 18 are candidates for LASIK. The procedure has the best results on patients who have a stabilized prescription, thus making patients under the age of 18 unlikely surgical candidates. Patients should be in good overall health before undergoing surgery. LASIK is generally used for common eye problems such as astigmatism, farsightedness, and nearsightedness. If you have a more complex vision problem, LASIK may not be the solution for you.

What the Risks of LASIK Surgery Are

While LASIK is a relatively straightforward procedure that boasts positive results, there is always a chance that it may not work. This could leave you with the possibility of having to continue wearing glasses or contacts. It is important to understand that LASIK surgery is still surgery, and complications can occur.

Understanding the Different Types of Eye Care Providers

To ensure you are getting the best eye care possible, it is important to know which type of eye specialist you should be seeing. Ophthalmologists, optometrists, and opticians all have the same overall goal of providing quality eye care, but their training and areas of expertise are different. Below, the roles of these three different types of eye care providers are explained.


An ophthalmologist is an eye doctor who has obtained an MD (medical doctor) or DO (doctor of osteopathy) degree. Ophthalmologists are surgically trained and are licensed to operate on the eye, and can perform corrective eye surgery. In addition to performing surgery, ophthalmologists diagnose and treat eye diseases, such as glaucoma. They can prescribe glasses and contact lenses, but generally focus on detecting and managing diseases.


An eye doctor that has a DO (doctor of optometry) degree is an optometrist. Optometrists are not medical doctors. An optometrist generally performs eye exams and vision tests. They can write prescriptions for glasses and corrective lenses, as well as medications to treat different eye conditions.


An optician specializes in fitting eyeglasses and making corrective lenses. Opticians work side-by-side with ophthalmologists and optometrists to fit and adjust prescriptions. Unlike individuals in the other two professions, they do not detect or treat diseases.

Overall Eye Care

All three types of eye care providers work together to serve a patient’s eye care needs. For example, an optometrist could perform an eye exam and prescribe corrective lenses; the optician could then fit the frames and lenses, and, if the optometrist detected an abnormality, an ophthalmologist could provide more advanced care.

When it is time for you to get your eyes checked, get the most comprehensive care in one office by seeing Dr. Mark Hornfeld, an ophthalmologist in New York. To learn more about the services available to cover your eye care needs, call (212) 580-8881.

Treatment Options for Macular Degeneration

One of the most common causes of impaired vision in adults is macular degeneration. This condition rarely leads to total blindness, but it does significantly impact a person’s ability to perform everyday activities, such as reading and driving. While there is no cure for macular degeneration, there are different options available to improve eyesight and stop the condition from worsening. Continue reading to learn about the available treatment options for macular degeneration.

Medicinal Options

Medication has become one of the preferred methods of treating macular degeneration. The medication works by preventing the production of blood vessels in the eye that contribute to vision loss. There are three different types of medication used: Lucentis, Eylea, and Macugen. Each medication achieves the same outcome, but they are administered in different time intervals. Lucentis is given monthly, Eylea is given every six months, and Macugen is injected every two months.

Laser Treatments

Laser macular degeneration treatments are used to eliminate existing, troublesome blood vessels. Thermal laser therapy utilizes a high-energy beam of light that targets the area of the retina to be treated. Photodynamic laser therapy (PDT) is a two-step process. With PDT, a light-activated drug is used, and is followed by a low-energy laser that is focused on the center of the macula.

Vitamin Supplements

Certain vitamins may decrease the risk of vision loss in some patients with macular degeneration. Vitamins C and E, beta-carotene, zinc, and copper may be helpful for controlling macular degeneration. There are ongoing studies to determine if other vitamins and minerals could also be effective in treating this vision condition.

To determine the right course of treatment for macular degeneration, start by talking to your eye doctor. If you are looking for treatment options for macular degeneration in New York, visit the office of Dr. Mark Hornfeld. Call (212) 580-8881 to schedule a consultation.
