Dr. Jonathan Kagan MD's Expert Contributions
Everything is listed in the package insert. I tell my patients when first starting Lumigan that the white of the eye may be red for the first two weeks and then usually clears and the lashes may become longer and thicker (many women in particular appreciate this known side effect). READ MORE
Closed head trauma may be associated with nerve damage to a specific muscle in the eye which then causes oblique or vertical double vision more frequently than horizontal double vision. Seek out a Neuro-ophthalmologist. READ MORE
This is not unusual and often frequent instillation of artificial tears without preservative over 6 months may help. If you have other hallmarks of ocular surface disease, your surgeon should be able to sort that out for you. READ MORE
If she has edema in her macula from the diabetes, then the reading vision will be affected. Also, cataracts will cause painless decrease of vision as well. READ MORE
Stopping restasis should not have any untoward effects other than reverting to your old tear insufficiency (dry eye) symptoms. Seek out an eye MD such as myself, a medical/surgical eye physician to advise you regarding this new red and irritated left eye. READ MORE
Seek out a pediatric ophathalmologist READ MORE
Consult with an ophthalmologist specializing in ocular surface (dry eye) disease. It is a multi-factorial problem. READ MORE

Definitely not. What sometimes happens after cataract surgery there is a membrane that may naturally become cloudy and will decrease the vision as if a cataract is coming back. This is treated with a YAG laser in the office. READ MORE
Many possible causes including not completely closing your eye during sleep. Consult with an MD ophthalmologist. READ MORE
The answer to this is short. Consult an Eye MD ophthalmologist regarding the many factors such as insufficient tears, irregular surface of the cornea and possible lens opacities (cataract) READ MORE
Get yourself to an Eye MD ophthalmologist for a complete exam and dilation of your pupils. This evaluation will let you know if you have any pathology in the retina such as a tear or hole. READ MORE
you may need to be refit. When the Ophthalmologist evaluates the cornea also inquire about your tear structure and what is called tear osmolarity. Normal is 280 milli osmols or less. Ask if you have any new vessels at the edge of your cornea (neovascularization.) READ MORE
astigmatism can be corrected with glasses, contact lenses and lasers. All these modalities should help improve your visual function. READ MORE
near sightedness or myopia can be progressive into your late 20's then in your 40's you may need a prescription of near vision (presbyopia). It usually will not reverse. READ MORE
Ask your eye MD if you have an irregular shape to the cornea or tear insufficiency. Both contribute to the comfort of your eye when wearing a contact lens READ MORE
Glaucoma is a silent chronic disease which if undiagnosed leads to blindness. Thus it is important to see an Eye MD physician to evaluate if you are at risk. Some risk factors include family history, color of your skin, thickness of the cornea, the pressure inside the eye, and the actual function and structure of the optic nerve itself. It is the damage to the nerve which leads to blindness. So glaucoma is multifactorial. Glaucoma is NOT just pressure. READ MORE
Simply put, Diabetes is one of the leading causes of blindness in the world. Indeed, most medical insurance companies require annual dilated retinal evaluations by an ophthalmologist to maintain your medical insurance. The blindness comes from bleeding inside the eye from tiny fragile blood vessels in the retina. READ MORE
