Insurance co are following medicare lead and are denying except for muscle functional loss. ...Read more

Can you tell me: are visual field defects always present in glaucoma?

Can you tell me: are visual field defects always present in glaucoma?

Frequently: Changes in the field of vision are one of the hallmarks of the diagnosis of glaucoma. The aim of treatment is to prevent this from happening and also to prevent it when present from progressing. Some cases are detected early when other changes hint strongly that glaucoma could be a problem, and so field defects might not have occurred yet in such cases. ...Read more

When having eyes dilated for glaucoma exam can an ophthalmologist detect diabetic retinopathy?

When having eyes dilated for glaucoma exam can an ophthalmologist detect diabetic retinopathy?

Yes if present : The dilated eye exam is exactly how we inspect the retina, optic nerve , blood vessels, and other parts for diseases. So if a person has diabetes and it is affecting their retina, we will find it and if necessary treat the complications. As it turns out, not having retinopathy (a good thing) doesn't mean that you don't have diabetes. Your primary doctor determines that. ...Read more

What are the tests for detecting early onset glaucoma?Does retinal examination help?Iot:18 both eyes.Feel contrast loss at night.Doc said lent opacity

Testing: Glaucoma is not the most common cause of loss of contrast at night. Visual field or oct testing can be done to detect early glaucoma, but with normal pressures such as yours and a normal exam, i would not expect them to show glaucoma. Those tests are usually done in patients that show physical signs of possible glaucoma such as elevated pressures or cupping of the optic nerve. ...Read more

11 month old diagnosed with decreased vision from visual acuity test (teller). However, prescription test after dilating the eyes shows no prescription needed. Eye health is normal. Why this conflict?

11 month old diagnosed with decreased vision from visual acuity test (teller). However, prescription test after dilating the eyes shows no prescription needed. Eye health is normal. Why this conflict?

The teller cards: Give a good estimate of visual acuity in children. But, since it is testing the first reaction of a child when the card is presented, things like tiredness or distractions can affect the accuracy. The prescription measured after dilation is more of an objective measurement and can be done accurately. Continue follow up as your eye doctor recommended. Be well. ...Read more

Optic Nerve RNFL OCT shows thinning temporal- both eyes, 20/20 both eyes, IOP 17 both eyes. Retinal exam normal. Is this significant

Optic Nerve RNFL OCT shows thinning temporal- both eyes, 20/20 both eyes, IOP 17 both eyes. Retinal exam normal. Is this significant

Response: Since all you provide are some brief findings regarding your retinas, I must conclude these tests were obtained due to some neurological symptoms. These results could be part of Multiple Sclerosis, if other signs and symptoms support the diagnosis. The thinning of the RNFL is notable, and should be followed up. Would a Concierge visit allow more in depth understanding? ...Read more

Can a large eye floater affect peripheral vision in a visual field test.

Can a large eye floater affect  peripheral vision in a visual field test.

Yes: Visual field testing will occasionally pickup small areas of visual field depressions if the floater is particularly large and thick, as some patients may have. Since they move, a repeat visual field should also show the depression to have moved. I would not however expect a large visual field abnormality from a floater and certainly l recommend an exam to rule out any problems by an eye md. ...Read more

Is it possible to get accurate visual field test with macular pucker decline in visual acuity, lights less bright & white computer screen looking gray?

Is it possible to get accurate visual field test with macular pucker decline in visual acuity, lights less bright & white computer screen looking gray?

Usually it is fine: You have defects in the central visual portion of your field of view - an area poorly outlined by most field testing devices. Field tests will define major defects which largely will register from the peripheral areas tested. Have you had a field tested in the past? Is there some condition being sought for with a field.? Your ophthalmologist would not order a field if he doubts the result. ...Read more

Can moderate macular pucker cause retinal detachment? Is that what doctor checks for on follow-up exams.

Can moderate macular pucker cause retinal detachment? Is that what doctor checks for on follow-up exams.

Check for swelling: of the retina and for worsening of vision. The pucker can wrinkle the underlying retina and cause cysts within it. If there is significant swelling, visual distortion, retinal disruption, then its a surgical treatment at that point. The pucker can stay unchanged for a long time or progress slowly but hard to predict. Good luck. ...Read more

Are there any glasses that could correct the vision at least 50%? I have albinism with eyes problems: nystagmus, astigmatism, photophobia.

Are there any glasses that could correct the vision at least 50%? 
I have albinism with eyes problems: nystagmus, astigmatism, photophobia.

Probably not: Vision in albinism is limited by the effect of the lack of pigment on the central vision which is permanently lowered. You are asking if eyeglasses can improve on your current best and that is unlikely assuming you have already seen an ophthalmologist for eyeglasses and eye evaluation. ...Read more
