It is not entirely known why certain ocular steroids contribute to cataract formation, and systemic steroids are much more likely to be an issue. There may be several reasons for this. Firstly, ocular steroids appear to be less effective in preventing cataract formation than systemic steroids at reducing intraocular pressure and, consequently, the severity of the ocular ocular hypertension, which may be responsible for both intraocular and intraocular steroid effects. Secondly, ocular steroids appear to be less effective in preventing ocular hypertension over several months than systemic steroids and, therefore, prevent ocular hypertension more quickly, in parallel with the ocular vascular effects. Finally, ocular steroids may affect keratoconus patients more, with an increased risk of keratoconus formation and/or ocular complications due to the increased pressure exerted on the keratoconus tissue. Indeed, this has been shown in several instances in which ocular steroids, which have been shown to be less effective at preventing ocular hypertension, were also found to be more efficient at reducing keratoconus formation.

Based on systemic steroids use, patients who were using steroids for different indications constituted the study population, and those with no steroids use were clustered as a control group.

Patients were stratified according to sex and age groups to examine differences in their baseline steroids use, in steroid use in the year of the event, and overall steroid use. Results indicated that only a small percentage of patients (3% to 4%) had baseline steroids use in the prior year. The majority (79% to 89%) had not used steroids that year, a result that might have contributed to the low number of patients experiencing an increase in steroid use (11%).

The duration of steroid use was similar to the earlier studies. Patients’ average duration of use was 3 months. After adjustment for factors related to use of other medications in the year before the event, there was no significant difference in a number of demographic, psychological, medical, and medical-related variables between patient groups including patient-rated health (P < .0001), patient satisfaction (P = .39), and overall satisfaction (P = .25).

In addition to the use of all or a portion of their own steroid supplies, patients also were assessed on other factors including the use of steroids to treat anxiety disorders (13), the use of prescription drugs (15), and other prescription drugs (3). Of those who did not use steroids as their primary or sole primary substance, 6% indicated that they had a history of previous steroid use and 16% were addicted to steroids.

The frequency of physical and psychologic sequelae differed between the 2 groups. Overall, the most common physical sequelae reported were sleep disturbances, headache, abdominal pain, and mood fluctuations. The most common psychological sequelae were depression, panic attacks, and stress, systemic steroids corneal ulcer.

It is not entirely known why certain ocular steroids contribute to cataract formation, and systemic steroids are much more likely to be an issue, so it might be that steroids that act at both sites are a reason, not just steroids from one site. Or it might be that cataracts only arise in certain people due to a combination of genetics and environmental factors.

However, it is important to consider that cataract development can happen even without steroids, and that people of Asian descent suffer more severe cataract formation than those of other races (I haven’t tracked down a study on this, but it seems likely to me). The issue, as you probably know already, is that most Asian countries have a diet rich in seafood, which contains a large amount of phycocyanin, a pigment that inhibits vitamin D binding. Even if a person does not eat seafood, they are likely to get enough vitamin D when exposed to light from the sun to counteract the loss of this pigment due to sunlight deprivation.

In the case of people of Asian descent, these foods also contain dietary zinc, something which helps protect the retina from damage caused by oxidative stress. While this doesn’t change the fact that many people would have a higher incidence of cataracts, a diet high in zinc could also benefit the eye itself, so a deficiency in dietary zinc is likely to affect the cataract system. Zinc deficiency, which would likely be a problem in the West, appears highly unlikely among Asians, as almost all the people in China, India, and South East Asia tend to eat an exceptionally high amount of seafood. So in the case of diet, the role of supplements could be to offset the effect of the seafood.

So at present, I do not see evidence of a link between dietary zinc and cataract formation, or a strong evidence of association between dietary zinc and cataract formation. However, there is an increasing body of evidence that high blood levels of zinc (hyperphosphatemia) appear to be linked to a higher risk of developing cataracts (Razzo et al., 2010; Mathers et al., 2012; Lee et al., 2014; Mathers, 2017), so there is certainly an increasing body of evidence that zinc supplements can potentially improve the outcome of cats with cataract, even in the absence of any other interventions to date. On the other hand, a lack of evidence for a link between zinc and cataract formation could easily cause people to believe that zinc supplementation is an ineffective treatment, as it has been widely used for centuries and has no actual medicinal value. To this end

Another alternative to prednisone and other related systemic steroids is topical steroids , which significantly reduces the risk of running into the unwanted side effects above.

Based on systemic steroids use, patients who were using steroids for different indications constituted the study population, and those with no steroids use were clustered as a control group.

The authors found that the steroid-using population in this cohort had lower rates of diabetes, cardiovascular events and mortality than those who were not on steroids.

The main reason for the differences in outcomes was that patients with and without a history of diabetes were more likely to be older and to have other diseases, such as hypertension, cholesterol disorders and renal disease.

In total, 41 percent of patients without steroids were diabetic, compared with 18 percent of patients who used them. While 14 percent of patients without steroids had heart diseases, 25 percent of steroid users did.

A history of hypertension, hyperlipidemia or liver disease also resulted in higher mortality rates among steroid users.

The authors wrote that further studies are needed to clarify the risks and benefits of using steroids for a variety of cancers.

The U.S. Preventive Services Task Force recommends using nonsteroidal anti-inflammatory drugs (NSAIDs) as part of a healthy lifestyle to prevent some of the commonly diagnosed diseases, including cancer.

However, the task force added that studies of the health risks of steroids among cancer patients are limited.

“Because steroids are used for nonmedical purposes and are increasingly used for medical purposes, the question remains as to whether and to what extent steroid use is associated with long-term adverse events,” the authors wrote.
