An increased sensitivity to steroids can result in an increase in eye pressure after just a few days of taking the medication. Symptoms of glaucoma may include: Blurry vision.
Most short-term prednisone side effects, like headaches, nausea, and weight gain, go away once the dose is lowered or the steroid is stopped altogether. Other potential side effects—like vision problems and osteoporosis —may be permanent.
Blurry vision is the most common eye problem associated with prednisone, but it's usually not serious. However, the risk of cataracts in both eyes increases for people who take more than 10 mg of prednisone daily for longer than a year.
In fact, steroids have been linked to causing or aggravating serious eye problems such as glaucoma and cataracts. A group of conditions that occur when drainage tubes within the eye become blocked. This prevents eye fluid from draining properly, leading to a pressure build-up.
In the majority of cases, steroid-induced acute rise of IOP typically normalizes within days of stopping the steroid and chronic forms take 1 to 4 weeks. In rare cases, IOP remains elevated, for which antiglaucoma medications or surgery may become necessary.
[8] Intraocular pressure (IOP) increase usually occurs 3 to 6 weeks following topical steroid use. However, it may occur earlier.
Steroid Medication May Increase Risk of Adrenal Insufficiency and Optic Nerve Damage.
Posterior subcapsular: This type of cataract may be caused by high doses of prednisone, extreme farsightedness, and retinitis pigmentosa. It forms at the back of the lens and tends to develop over months, rather than years.
Middle-age for men: as testosterone levels naturally drop with age, men may experience dry eyes and blurry vision, in the same way menopausal women do. This is due to changes in the tear ducts and the oily film in the eyes that keeps them moist.
A gradual reduction in prednisone dosage gives your adrenal glands time to resume their usual function. The amount of time it takes to taper off prednisone depends on the disease being treated, the dose and duration of use, and other medical considerations. A full recovery can take a week to several months.
Fluid retention is one of prednisone's most famous side effects. “'Moon face' is common, which is swelling in the face that can occur after you've been on steroids for a long time,” Dr. Ford notes. “You can also get swelling in the legs and midsection.”
Prednisone has a tendency to raise the level of glucose, or sugar, in the blood, which can cause increased body fat or diabetes in some people. It is important to avoid "simple" carbohydrates and concentrated sweets, such as cakes, pies, cookies, jams, honey, chips, breads, candy and other highly processed foods.
People consuming oral and inhaled steroids are at a comparatively higher risk of developing a cataract. As a result, the person starts to see glare or halos at night; the person may have blurry vision, double vision, eyelid drooping, problems with peripheral (side) vision and problems seeing at night.
It takes approximately 16.5 to 22 hours for Prednisone to be out of your system. The elimination half life of prednisone is around 3 to 4 hours. This is the time it takes for your body to reduce the plasma levels by half.
A 5-day course of prednisone can cause short-term side effects, including changes in mood, appetite, sleep, and energy. The severity of the side effects depends on the dose of prednisone. Low doses are less likely to cause adverse effects than high doses of prednisone.
The prevailing view regarding the mechanism of steroid cataract formation holds that glucocorticoids are covalently bound to lens proteins resulting in destabilization of the protein structure allowing further modification (i.e. oxidation) leading to cataract.
Studies show that long-term use or high-doses of steroids can promote cataract formation. People taking a combination of oral and inhaled steroids are at the highest risk.
Steroid-induced posterior subcapsular cataracts (PSCs) exhibit three main distinctive characteristics: (i) association only with steroids possessing glucocorticoid activity, (ii) involvement of aberrant migrating lens epithelial cells, and (iii) a central posterior location.
Conclusion: Long-term corticosteroid therapy can be complicated by severe, chronic and recurrent CSCR and occasionally peripheral exudative retinal detachment. This may result in subretinal fibrosis and permanent loss of vision.
Cloudy or blurry vision
This is the most common symptom of cataracts. It can affect both distance and reading vision which may appear foggy. If left untreated, the clouding of the lens means the cataract will worsen, with less light able to get through the lens.
Central serous chorioretinopathy (CSC) is a serious side effect of steroid medication that causes a buildup of fluid underneath the retina. This can lead to retinal detachment and vision loss. Symptoms of CSC may include: Blurred vision in one or both eyes.
If the steroids are discontinued in time, the eye pressure usually returns to previous levels. Unfortunately, patients who have repeated steroid exposure are at risk for irreversible steroid glaucoma.
Steroid-induced glaucoma may develop after application of steroid preparations applied to the skin of the eyelids. This elevation occurs most frequently with chronic use, such as in patients with atopic dermatitis, and in patients with a family history of glaucoma.
