Normal field vision test. Dilated optic discs small w/slight asymmetry. Suspicious oct scan. Eye pressure 27. Family history. Suspect for glaucoma?

Yes: It is important that your eye pressure be monitored closely and that the visual fields and oct are tested are a regular basis. I suggest you see an ophthalmologist regularly. There are usually no symptoms of glaucoma that you will experience. ...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

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

Uc flare with thin stools, chunks of blood in stool, and frequency. Egd, colonoscopy, biopsies & digital perianal & rectal exam all normal. confused?

UC is long-term: Ulcerative colitis is a lifelong inflammatory disease of the lining of the large intestine and rectum, that may have systemic consequences, is often relapsing, and can lead to colon cancer. Flares may occur acutely, even after an unremarkable colon evaluation. Don't delay in ruling out superimposed infection, & seeking help from your gastroenterologist. Call him/her now-- ...Read more

Could a lazy eye with 6/18 visual acuity affect academic performance.?

Could a lazy eye with 6/18 visual acuity affect academic performance.?

Usually not: If the vision in one eye is normal, the lowered vision in the fellow eye will not impede academic achievement. There is little in academics that requires excellent vision in both eyes. The only areas affected would be those requiring stereoscopic vision. I have know doctors, lawyers, engineers and professors who have a lazy (amblyopic) eye. ...Read more

Progressive macular pucker 20/30 vision, distortion & glaucoma. Visual fIeld good,nerve damage 30-45%.Would vitrectomy cause glaucoma to progress?

Possible: Vitrectomy and glaucoma may have an association. It is suspected that glaucoma occurs more often in patients who have had vitrectomy and subsequent cataract surgery. An ongoing clinical trial is aimed to answer this question with more clarity.

What is the risk of bowel perforation from CT colonography "virtual colonoscopy"??

What is the risk of bowel perforation from CT colonography "virtual colonoscopy"??

Not invasive.: A traditional colonoscopy is invasive; the fiber optic camera is passed through the colon, and therein causes the low risk of perforation of the colon. A CT colonography is not invasive; it's just a fancier CT scan, so there's nothing to directly cause a perforation. ...Read more

Bowel issues 3 years, 4 Ct scans over that time with oral contrast, sigmoidoscopy to 35 cm, only diverticulosis seen, chances of missed cancer?

Bowel issues 3 years, 4 Ct scans over that time with oral contrast, sigmoidoscopy to 35 cm, only diverticulosis seen, chances of missed cancer?

Slim: in spite of the low chance of missing a cancer, a complete colonoscopy would examine the rest of the colon not visualized on sigmoidoscopy. CT is only fair to see colon cancers unless large because stool may get in the way. If you are still concerned then talking to your doctor may resolve these issues. ...Read more

Simple partial seizures common idiopathic epelipsy? Brain tumor? No other symptoms. Passed neuro exam - reflexes, gait, strength, eye exam -perfectly.

Brain tumor: An MRI of the brain will determine if there is a brain tumor. Reducing or eliminating the seizures is the first priority. The anti-convulsant (anti-seizure) medication prescribed by your neurologist is specific to the seizure type. Discuss the side-effects of each medication to help you cope with seizures. ...Read more

Colonoscopy 4 and 9yr ago neg. Parent had colon ca. No hemoccult done til recent food poisoning; 1 is +. Is virtual or visual colonoscopy best? Feelok

Optical vs virtual: While both optical colonoscopy & CT colonography (virtual colonoscopy) examine the lower GI tract, & both require inflation of the colon with air, the optical exam offers several potential advantages in your case where your risk of finding a lesion is high (due to family history & finding occult blood): it is performed sedated; it permits biopsies of inflamed tissue & permits removal of lesions. ...Read more

US protocol for colonoscopy mention to get samples from bowel tissue even there is no visual problem. Is it right or not?

Not standard practic: I doubt that it is the US Protocol to biopsy normal looking mucosa unless there is a suspicion of some rare inflitrative illness (like Amyloidosis etc). If you do not have symptoms of colon origin, there would be little reason to biopsy normal looking mucosa. What are you searching for? If you can define that, we can guide you better. ...Read more

Pain between anus and tailbone. Pain shooting down veins in leg. Short of breath. Rcvd reg colonoscopy, vein and artery scan. No visual sign of cause.

Should questionmuscu: Would also question musculoskeletal. Veins don't conduct pain beauty feel thespian along their course. We would think of irritated never or muscles. It is important to know what makes it better and what makes it worse. Ask your gastroenterologist what else they think. Also look a nerve pinching of the sacral area.

What is a colonoscopy?

What is a colonoscopy?

Look inside colon: You are sedated (very sleepy, but still breathing on your own). The endoscopist places an instrument through your anus and then passes it into the colon to carefully exam the colon for polyps, cancer, etc. If any abnormalities are found a biopsy may be done. Typically, it is painless - the only bother is cleaning out your bowels beforehand and even that's not so bad. ...Read more

Are colonoscopies necessary?

YES!: A colonoscopy is a safe, thorough examination of your entire colon under sedation to screen for polyps, or to diagnose bleeding issues or other colon abnormalities such as diverticulosis or hemorrhoids. Small growths like polyps rarely cause symptoms until they grow larger, and can lead to colorectal cancer. You should be screened at least at age 50 or sooner if you have any rectal bleeding. ...Read more

How to prep for a colonoscopy?

Lots of options: There are a lot of different regimens for doing a colonoscopy prep. It depends on your gastroenterologist what they prefer. Ultimate what they want is a clean prep, so you should not have any stool in your colon when they look. You will have a sense of whether your prep is complete when you look in the toilet bowl and you shouldn't see any solid material left. ...Read more
