Welcome to the Retina service at Stony Brook University!

We are a team of highly trained and experienced ophthalmologists specializing in the treatment of disorders that affect the retina and vitreous. We treat the full spectrum of retinal conditions using the most advanced tools available in our state-of-the-art facilities.  We specialize in:

  • Age-related macular degeneration
  • Retinal tears
  • Retinal detachment (separation of the retina from the back of the eye)
  • Vitreous detachment (gel-like substance detaches from retina)
  • Diabetic eye diseases, including diabetic retinopathy
  • Vitreous hemorrhage (bleeding occurs in the vitreous)
  • Retinal vein and artery occlusions (RVO) (blockage of a blood vessel in the retina)
  • Macular hole (a small hole that forms in center of retina)
  • Macular Pucker (a membrane or scar tissue that alters the anatomy of the retina)
  • Lattice degeneration
  • Floaters
  • Intraocular inflammation (uveitis)
  • Hereditary disorders
  • Ophthalmic complications arising from systemic disease


Our highly-skilled retina specialists are able to perform the most intricate procedures with lasers or traditional surgical instruments to enhance vision or prevent vision loss for many eye conditions.

With the latest technology and non-invasive imaging techniques, our retina specialists are able to view all individual cell layers of the retina and assess the severity of various retina diseases and vitreous conditions. Our advanced diagnostic tools allow us to provide you with the most effective treatment methods for your individual condition.

We offer all the surgical techniques available to repair a retinal detachment including small gauge pars plana vitrectomy, scleral buckle, and pneumatic retinopexy (injecting a gas bubble in the office).

Stony Brook offers laser procedures in our on-site laser suite for the treatment of retinal tears.

For macular degeneration, our treatment focuses on slowing the progression of the disease and, sometimes, on restoring vision that may have been compromised. Depending on the type of macular degeneration, our doctors may recommend interventions such as lifestyle changes, nutritional supplementation, injectable medications, or rarely, photodynamic therapy.


At Stony Brook Ophthalmology all of our patients are treated with dignity and respect. We will listen closely to any symptom patients have and use the most up-to-date medical treatments to obtain the best possible outcome.
