Quality glaucoma diagnosis and care
Glaucoma is pressure damage to the optic nerve. We have decades of experience and a highly trained staff to accurately diagnose and effectively treat all types of adult and adolescent glaucoma.
Measuring the extent of damage crucially determines how much to lower your intraocular pressure. (If there is enough damage to affect a visual field test, it is generally preferable to keep the pressure 16 or lower.)
The extent of glaucoma damage, and the likelihood of damage worsening, is assessed by considering: your family history, intraocular pressure (sometimes measured 2 ways), corneal thickness, visual fields, OCT scans of the nerve fiber layer, contours of your optic nerve, and size of your eyeball.
We have special expertise in non-standard dosing of eye drops: instead of using 1 or 2 medicines at the dosage frequency advised by the drug company, it is often more effective and less irritating to use 3 medicines, but less frequently, using only 1 or 2 drops a day. The net effect is lower pressure without a red eye. Please explore our website to learn more…

Our Doctors
Peter E Libre, MD
Dr. Libre earned his undergraduate degree from Yale (Biology) and his MD from the University of Maryland; he served his ophthalmology residency at Columbia U Medical Center and glaucoma fellowship at Cornell NY Hospital. He has been on the Columbia faculty since 1994 and authored peer-reviewed articles in glaucoma and cataract surgery. He has performed many thousands of cataract surgeries, glaucoma surgeries (including trabeculectomy, Ahmed valve implant, IStent, Kahook, Hydrus) and laser treatments (SLT, iridotomy, iridoplasty, cyclophotocoagulation, micropulse cyclophotocoagulation).
He speaks fluent Swedish, passable Spanish and Italian, and bit of ophthalmic Haitian Creole.
Getting outside is a priority: he bikes, roller skis or kayaks to work; tends hens and vegetable gardens; loves snow, mountains, wind and water.

Anita A. Singh, OD
Dr. Singh earned her undergraduate degree from University of California, San Diego (Biochemistry) and her Doctor of Optometry degree from State University of New York, College of Optometry. She completed clinical training at Woodhull Hospital in Brooklyn, Somers Eye Center and West Point Military Base. After graduation, Dr. Singh practiced medical optometry in the Bronx and Westchester County, and later worked as the clinical director of a refractive surgery center in CT before joining CT Glaucoma Associates.
Dr. Singh is experienced in managing glaucoma, cataracts, macular degeneration, corneal disease and dry eye. She speaks conversational Spanish. When not at work, Dr. Singh enjoys spending as much time outside as possible, caring for her flower garden, and tackling home improvement projects with her husband.
“Everything should be made as simple as possible, but not simpler.”
– Albert Einstein
Expensive and complicated is often worse than inexpensive and simple.
For example, most styes are blocked, not infected, glands. So the right treatment is hot compresses to melt the oil plugs, not antibiotics trying to treat an infection that is not there.
Similarly, most dry eye is due to inadequate oil flow through the oil glands. Hot compresses melt the oil plugs, and improve the flow of oil, which protects the cornea and slows evaporation of the tears. Unfortunately, expensive patented dry eye medications, so marginally effective that they were never approved in Europe, are commonly prescribed without even trying hot compresses — which are usually more effective.
Many glaucoma patients with chronically red, uncomfortable eyes are told to add more products to their eyes: allergy drops, lubricating drops, anti-inflammatory drops. However, the effective approach is less, not more: use the fewest drops possible and prescribe only preservative-free medication — plus hot compresses at least a few times a week to keep the oil glands flowing.
Cataract patients often pay hundreds for postoperative drops: a non-steroidal anti-inflammatory, a steroid, and an antibiotic — but this expense and complexity is of uncertain value. The non-steroidal drop is very important, but there is no evidence that the expensive new products are better than the older generic ones. The expensive steroid drop can be easily replaced with an inexpensive injection at surgery — or an expensive steroid implant that has not been shown to be better than injection. And there is growing evidence that antibiotics injected into the eye at surgery are critical, while antibiotic drops do not seem to be helpful. (Dr. Libre, with technician/student Sean Matthews, published a study of injectable antibiotic effectiveness: “Endophthalmitis prophylaxis by intracameral antibiotics: in vitro model comparing vancomycin, cefuroxime, and moxifloxacin” (Journal of Cataract and Refractive Surgery, 2017).
