FUNDUS FLUFLUORESCEIN ANGIOGRAPHY USING DYE

[abaker]

I am CKD stage 3 with creatinine 1.6. I have been diagnosed with Macular degeneration and the Retina doctor wants me to undergo a OCT+ICG+SPECTRALIS+FFA + OPDOS FUNDUS to decide the course of treatment. My concern is that since they are using dye injection for the Fundus Fluorescein Angiography, will it affect my kidney function? I shall be grateful if somebody comment on this subject

Sorry can't help. Your doctor is best placed to answer your question before your angiography.

Hello abaker. I don’t personally know much about the impact of these dyes that they inject for x-ray purposes on the kidneys, but I myself, have retinopathy (from diabetes), and I’ve also had a similar test done for my eyes years ago. I found this website (link below) that says it is possible that it can harm the kidneys, but I believe the percentage they state is rather low. I hope you will find it helpful. If this doesn’t answer your questions, and you’re still worried, the best thing to do is to try asking your doctor or nephrologist. S/he will be able to provide better direction for you. Wishing you all my best, dear. Please do take good care, and keep us posted. God bless. 💕🙏

I also have stage 3 CKD and Macular Degeneration. I’ve had dry macular degeneration for years now and my doctor hasn’t done that test. She checks my eyes every 3 months for any changes. I have lost one kidney due to this disease, but the other is doing double duty. My Nephrologist has told me to refuse the dye they inject for the MRI’s or any other test, because it is really bad for the kidneys. If I were you, I would tell you doctor that you have kidney disease and refuse the test. My eye doctor has told me to take Omega 3’s (fish oil) and eat a lot of leafy greens. So far, my macular degeneration has not progressed. Is yours the dry or wet macular degeneration?

Some dyes are a real problem for CKD patients. You need to consult a nephrologist who actually knows about this before you decide. Then you need to decide your priorities. Finally, you may need to consult a different eye doctor to determine his or her recommendations for treatment. This is a complex issue that requires careful consideration.

You really need to check with your nephrologist.However, I have had a transplant and had to have a CT scan done with contrast in April. My doctor had me drink more water than usual a couple days before the study and for several days after. I repeated my renal labs 2 weeks after the scan.

My hubby, now with a kidney transplant, has undergone a number of scans using contrast dyes to stent his heart and later to fix a transplant problem, etc. I agree with everyone who is urging you to talk to your nephrologist about this to help with your decision making. If the decision is made to proceed, mention your kidney situation to the radiologist/ophthalmologist right before s/he takes you in. The radiologist may make some concessions then and there, e.g, a lighter concentration of dye, etc. Discussions held in advance often don't move to the people doing the procedure.

I have read that xray contrast used to be able to temporarily and or permanately reduce kidney function if you already have kidney function problems. Ive also read that with the newer contrast and proper preperation before the contrast thqt this is now rare. I would definitely discuss with dr to get clarification.

[purejoynow in reply to silverfox81]

very interesting. I would also like to read this. would you by any chance have a link?

[silverfox81 in reply to purejoynow]

You could send me your phone number and I can text you the exact book quote from his book if you would like.

[purejoynow in reply to silverfox81]

no, but you can send me the title of the book right here if you wish.

[silverfox81]

Dr. Stephen Rosansky who is a nephrologist wrote about it in chapter four of his book "facts about kidney disease" I bought the book off amazon. I dont have a link to share on here bc its on my kindle.

Im sorry his book is titled "learn the facts about kidney disease"

I have a lot of experience with this subject. You see I have stage 4 cancer in addition to CKD. This requires me to get Xrays, MRI's, CT's, OFTEN!!! I have never had the need for a dye for an Xray. For MRI's and CT's I always get dye (no less than every 2 months, for the past 3 years. My CKD has remained the same. I am Stage 3 at egfr 43. The key is NOT that you have CKD (so all the doctors tell me....oncologist, neurologist, primary care) but what level your egfr is at. In fact at the labs and hospitals where I get these tests they will NOT inject a dye unless the egfr is at least 40. Before receiving the dye I get a small IV of fluids. After the test I am instructed to drink as much water as I can for the rest of that day. NOW, they do NOT give me the full injection of dye. But give me a reduced amount.Now there are contrasts (dyes) that you drink, which are NOT injections. These are primarily given for scans/tests of the abdomen. These are NOT harmful to the kidney but you are still instructed to drink lots of water after the test. Remember I am getting these tests often. My primary care instructs me that even if "harmful" amounts were to be given, just doing this occasionally (lets say one time this year) it is not going to destroy your kidney nor change your egfr for that one experience. Also, the key to these "dyes" is if they contain iodine. That is what is most harmful.
