Common Ophthalmological Conditions and Treatments

Learn about common eye problems from your New York ophthalmologists.

Are you familiar with common eye conditions? Dr. Christopher Coad and Dr. James Kirszrot, ophthalmologists in New York, NY at ophthalmological conditionsChelsea Eye Ophthalmology, share information on several eye conditions and diseases and discuss treatment methods.


Commonly called "pink eye," conjunctivitis is an inflammation of the conjunctiva, which forms the white part of the eye and lines the eyelids. Symptoms of conjunctivitis include redness, itching, burning, swollen eyelids, sensitivity to light and tearing. Although the viral form of conjunctivitis will get better on its own, you'll need to use prescription antibiotic drops if you have bacterial conjunctivitis.


Have you ever watched cobwebs or strings float across your field of vision? These spots, called floaters, are more common as you grow older. The vitreous, a gel-like material that fills the center of your eye, gradually shrinks with age. When it does, small strings occasionally detach and float through your eye. In most cases, floaters are harmless and don't need treatment. If you suddenly notice many floaters, call your ophthalmologist immediately. A dramatic increase in floaters can be a sign of a retinal detachment.


Cataracts cloud the clear lens in your eye, affecting your focusing ability. If you have cataracts, you may notice:

  • Decreased color intensity
  • Blurry vision
  • Hazy vision
  • Sensitivity to light
  • Difficulty with your vision at night

Cataracts are removed and replaced with artificial lenses when they begin to significantly interfere with your vision.


Glaucoma is a serious eye disease that can lead to blindness. Because the disease often has no symptoms initially, you may not realize that anything is wrong until you experience loss of vision. Glaucoma damages your vision by increasing the pressure inside your eye. Glaucoma tests, part of your annual eye exam, are essential screening tools that can help you avoid permanent vision loss. If you do develop glaucoma, medication can help prevent your condition from worsening.

The acute form of glaucoma can develop very suddenly. In some cases, it may seem as if a curtain has dropped in front of your eye. You may also experience severe eye pain or headache, rainbow halos around lights, nausea and blurred vision. If you notice any of these symptoms, contact your ophthalmologist immediately or go to the emergency room.

Your ophthalmologist offers treatments that can help you manage many common eye conditions and diseases. To schedule your ophthalmology appointment, call Dr. Coad and Dr. Kirszrot at Chelsea Eye Ophthalmology, in New York, NY, at (212) 220-0066.

  • "Cannot recommend Dr Coad & his lasik coordinator Nicole enough. They are wonderfully supportive and gentle that even if you are nervous it will be difficult to stay that way around this supportive duo! Without a doubt recommend going to see them, they are worth the additional care and cost for a full-service experience that are there just to help you & give you the best vision possible. Thank you Dr Coad & Nicole."

  • "Dr. Coad and his staff made the experience of having a cataract removed the best it could possibly be, from evaluation to discussing options to being reassuring when the surgery began, to follow-up. The evaluation process was efficient, yet at no time did I feel as if it was anything but personal. His staff at all times were both professional and welcoming. Vace, the surgical coordinator, did everything to make sure the surgical process went smoothly.
    As to Dr. Coad himself, I can't say enough. His skill is absolutely top-notch, but it was the concern that he took in making sure that I understood all of my options, and his reassuring manner before, during and after the surgery which makes it easy to recommend him to the fullest to anyone who needs ophthalmic care."

  • "Had a five star experience at Chelsea Eye! I went to Dr Yoon for an eye exam and she was extremely friendly, helpful and down to earth! I have met all the staff and they are very friendly and easy to talk to. Hugo in particular was wonderful to work with during the exam. It was a breathe of fresh air coming to this practice and I highly recommend going here for an Optometry appointment or Opthalmology appointment with Dr Coad."

  • "Can I please take a moment and talk about how awesome Dr. Jay Yoon is?!

    I would be friends with this woman! I went in freaked out about a blood vessel on my eye and in total hypochondriac mode (is it a stroke? Is this connected to my brain? Is it gonna spread?). She laughed and calmly said "looks like you've always had this and it's fine and here are some drops cause your eyes are dry and here's my great primary doctor who I recommend since you don't have one."

    She was very funny and relatable and cool - she didn't try to rush me away and she was honest about everything too and so helpful.

    I've already started recommending her and now I'll do it on here: book an appt and be treated so warmly."

  • "Dr Coad and Nicole were both absolutely wonderful. After my brother had LASIK surgery, I decided to go ahead and do the same.

    Both Nicole and Dr. Coad are very proficient in their work. They answered any and all questions that I had, and calmed every nervous feeling that arose from the start, up until the surgery.

    Going through the surgery I was EXTREMELY nervous and Dr. Coad walked me through the entire procedure (before and during) and made my whole LASIK experience a breeze.

    I can not recommend them enough. If you are interested in LASIK Dr. Coad is the only doctor I would trust."

  • "This team is the absolute best. Christine is a gift from the gods and makes you feel comfortable supported and amazing. She really got me through my anxieties about my recent lasik surgery - which went great! Dr Coad is the best. A fantastic team, a simple process - I highly recommend this team - if you've ever considered lasik (like I have for the last 20 years) make an appt with this great group. You'll be happy you did."
