Cataracts (Definition)

Occurs whent here is a clouding (or change in protein composition) of the normally clear lens (which is located behind the pupil and iris) inside the eye. Cataracts are most commonly due to aging, but can be congenital (born with it), due to trauma or uveitis (eye inflammation). Can be worsened by long-term topical steroid ...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

Early stage glaucoma & moderate stage epiretinal membrane same eye not affecting vision much now. W/both diseases potential for central vision loss & peripheral vision loss causes anxiety. Prognosis?

Early stage glaucoma & moderate stage epiretinal membrane same eye not affecting vision much now. W/both diseases potential for central vision loss & peripheral vision loss causes anxiety. Prognosis?

The risk is very low: An epiretinal membrane is a common finding in 60 y/o female and typically remain visually insignificant. If it becomes visually significant, surgical treatment is very successful. Mild glaucoma is very treatable, and with appropriate followup and treatment, peripheral vision loss can be prevented. Central loss is extremely rare. ...Read more

How are eye vision test generally scored?

How are eye vision test generally scored?

Compared to standard: The chart used to test the eye is calibrated for normal vision at 20 feet. The outcome achieved is compared to what a normal eye can see at 20 feet. So if you can only see at 20 feet what a normal eye sees at 40 feet, your vision is considered to be 20/40. This is measured with and without corrective lenses at distance and at near. The vision with correction is considered to show the true vision. ...Read more

Vision issues for4yrs;had b/l cataract surgery-no relief-finally diagnosed w/ vertical diplopia.dr ordered MRI w/o contrast due to44GFR.need contrast?

Perhaps: If you have no other symptoms or signs, and the MRI without contrast is normal, this is probably due to a 4th cranial nerve problem (atherosclerosis/hypertension) or decompensation of an old strabismus. If it can be treated with prisms in your glasses, you can just follow it. If you are really unhappy, then get Peds oOhthalmology consult. Get Radiology consult for imaging question. ...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

Glaucoma rt. eye.Humphrey field test full within normal limits.DMV peripheral vision test 50 deg left & 70 deg right. Dr says DMV test wrong.Possible?

Glaucoma rt. eye.Humphrey field test full within normal limits.DMV peripheral vision test 50 deg left & 70 deg right. Dr says DMV test wrong.Possible?

Depends: Most Humphrey testing is 30-50 degrees from the center simply because ones that measure farther out take too long a time and most glaucoma changes start in the center. The DMV tests check a couple of horizontal points about 60 degrees and 130 degrees out. So it depends upon which testing you went through. Hopefully, with a glaucoma diagnosis, you are seeing a real doctor - an ophthalmologist. ...Read more

Could glaucoma eye pressure test be done before eye dilation?

Yes: Intraocular pressure should always be measured prior to dilation as it typically increases a little after dilation, especially when monitoring for glaucoma. There are a few conditions where it may be checked after and eye doctors will typically recheck pressures after dilation to ensure accuracy of their technician, but as a rule, this should be documented prior to dilation. ...Read more

Can you tell me about tests for cataracts and glaucoma?

There are several : tests utilized separately for glaucoma and for cataract evaluation. For glaucoma: eye pressure, Slitlamp examination of the eye focusing on the optic nerve, gonioscopy to look at the angle structures, visual field test to look for subtle patterns of vision loss, a retinal nerve fiber layer analyzer to evaluate patterns of nerve loss, and fundus photos to monitor for change in optic nerve. ...Read more

Epiretinal membrane in 1 eye & cataracts in both. Are there any tests to determine which condition is likely causing glare & hazy vision when driving?

ERM & Cataracts: Epiretinal membranes (ERM) can affect central vision. A PAM (Potential Acuity Meter) can determine if it is just the cataract affecting general vision or the ERM. If ERM small, might still have 20/20 with PAM. Brightness acuity test (BAT): generally tells us how bad the cataract is. OCT (optical coherence tomography) tells us how significant ERM is. Frustration is in fact: still no guarantee which ...Read more

What was cataract treatment like in the 1900's? How has it improved since then?

Risky: Starting just prior to 1900, topical anesthesia was available so cataract surgery could be performed painlessly. The procedure at the time involved opening the eye and bluntly removing the entire lens and hoping that would be all that would exit the eye. A strong eyeglass was required afterwards. Now with ultrasound and microscopes, etc. cataract removal can be done safely and predictably. ...Read more
