The excellent news is that diabetic retinopathy (DR) could be identified lengthy earlier than it really begins to influence your imaginative and prescient. The situation could be very treatable, and probably even reversible, particularly when caught early.
Medical doctors have a great understanding of what causes DR: excessive blood sugar, hypertension, and, to a lesser extent, excessive ldl cholesterol. Diabetic retinopathy could be very delicate to metabolic well being, and lots of the medicines that individuals with diabetes generally take can have an effect on its development and growth — for higher or for worse.
This text will evaluate the medication that we all know (or suspect) would possibly worsen diabetic retinopathy.
Warning
A fast phrase of warning: This text shouldn’t be taken as medical recommendation, and no affected person is certified to determine for themselves whether or not to keep away from any drug listed right here. Many of those medicines are necessary for the well being of tens of millions of adults, and their advantages might simply outweigh no matter impact they may have on DR.

The Two Diabetes Medicine That (Would possibly) Make DR Worse
Most diabetes medication have useful results for diabetic retinopathy, slowing its development and probably even serving to to reverse the harm. Taking your glucose-lowering medicines as prescribed by your physician is totally top-of-the-line methods to guard your self from DR.
There are, nonetheless, one and probably two exceptions to that rule, as described by a current survey of the subject within the medical journal Eye.
Thiazolidinediones (TZDs)
TZDs have been known as “the forgotten diabetes treatment.” These capsules straight enhance insulin resistance, a root reason behind kind 2 diabetes, however have been deemphasized by authorities as a consequence of issues over dangerous negative effects, together with heart problems.
Though these medication are more and more out of style, they’re nonetheless generally prescribed. As of 2019, about 8 p.c of individuals with kind 2 diabetes used a TZD.
TZDs carry a identified threat of diabetic macular edema (DME), an particularly damaging type of diabetic retinopathy that impacts our keenest imaginative and prescient within the middle of our eyesight. TZDs could cause fluid retention, which seems to exacerbate the swelling of blood vessels that characterizes DME. It solely occurs in a small variety of circumstances — fewer than 3 p.c of those who use the drug.
There at the moment are two sorts of TZDs in the marketplace:
- Rosiglitazone (Avandia)
- Pioglitazone (Actos)
Fortunately, cessation is related to speedy eye enchancment.
Ozempic
There’s some proof that semaglutide (Ozempic), a GLP-1RA, might improve the incidence of diabetic retinopathy.

Even when the affiliation is actual, it’s very attainable that your personal physician would conclude that semaglutide is well worth the threat. Ozempic is a very efficient drug for individuals with diabetes, usually conferring each speedy glycemic enhancements and weight reduction.
It appears attainable that Ozempic’s effectiveness, in reality, explains its unfavorable impact on the eyes. Opposite to all expectations, speedy enchancment in glucose management can really worsen diabetic retinopathy. That is known as “early worsening,” as a result of the eyes will worsen earlier than the foremost long-term advantages of higher blood sugar management change into evident.
Specialists don’t consider that that is essentially a motive to keep away from Ozempic. A current dialogue of the difficulty by consultants from the American Academy of Ophthalmology recommended that “early worsening” from Ozempic is each “short-term and manageable,” though it does name for elevated scrutiny from eye medical doctors.
Different Medicine With Adverse Metabolic Results
Medicine That Enhance Blood Sugar
Some medicines are identified to trigger blood sugar spikes:

The proof linking excessive ldl cholesterol with DR isn’t fairly as robust, though we do know that some cholesterol-lowering medication (particularly fibrates) considerably cut back the incidence of DR.
These are a number of the commonest medication which can be believed to raise “dangerous” ldl cholesterol (LDL and/or triglycerides), which can or will not be threat components for DR:
- Steroids

It’s due to this fact in all probability truthful to contemplate any medication that trigger weight acquire as potential threat components for DR.
A few of the commonest medication related to weight acquire embody:
