Glaucoma is a severe eye situation that damages your optic nerve, the connection between your eye and your mind. This injury results in irreversible imaginative and prescient loss and even blindness. Usually, glaucoma is linked to elevated strain inside your eye, referred to as intraocular strain (IOP).
This strain harms the fragile nerve fibers of your optic nerve. Consider the optic nerve like a cable carrying visible info to your mind; if that cable is broken, the sign will get misplaced, leading to imaginative and prescient issues. There are various kinds of glaucoma, however the most typical is open-angle glaucoma.
This kind usually develops slowly and painlessly, with no noticeable signs within the early phases. This makes it significantly harmful, as folks might not notice they’ve it till vital imaginative and prescient loss has occurred. Different, much less frequent varieties of glaucoma exist, however open-angle glaucoma accounts for the overwhelming majority of instances.
A number of elements improve your threat of creating glaucoma. These embrace age (being older will increase your threat), household historical past of glaucoma, sure ethnicities and excessive IOP. Now, analysis has revealed one other threat issue: the usage of statin medicines.
The Hyperlink Between Statins and Glaucoma
Statins are a extensively prescribed class of medicines used to decrease levels of cholesterol within the blood. They work by blocking an enzyme in your liver that is accountable for producing ldl cholesterol. Latest analysis uncovered a hyperlink between statin use and an elevated threat of creating glaucoma.
A 2024 examine revealed in Ophthalmology Glaucoma examined knowledge from the All of Us (AoU) Analysis Program, a large-scale analysis effort geared toward understanding well being and illness.1 This examine checked out 79,742 adults aged 40 and older who had excessive ldl cholesterol (hyperlipidemia) and accessible digital well being file (EHR) knowledge. The researchers analyzed the connection between statin use and the incidence of glaucoma inside this group.
The AoU examine discovered a notable affiliation between statin use and an elevated probability of getting glaucoma.2 Particularly, they discovered that statin customers had a 13% increased probability of getting glaucoma in comparison with those that didn’t use statins, after adjusting for confounding variables.
The researchers additionally checked out how levels of cholesterol and age play a task on this affiliation.3 They discovered that the hyperlink between statin use and glaucoma was stronger in folks with optimum or excessive low-density lipoprotein (LDL) levels of cholesterol.
These with optimum LDL who used statins had a 39% elevated probability of glaucoma and people with excessive LDL had a 37% elevated probability. Moreover, they discovered a stronger affiliation in folks aged 60 to 69, with a 28% elevated probability of glaucoma for statin customers on this age group. This means that age could also be an element within the threat related to statin use and glaucoma.
Statin Use Length and Glaucoma Threat
A key query within the statin-glaucoma connection is whether or not the period of statin use performs a task. A 2023 examine revealed in Scientific Studies investigated this utilizing a big Japanese claims database.4 This examine particularly seemed on the relationship between statin use and open-angle glaucoma in Japanese sufferers with excessive ldl cholesterol. The researchers used a nested case-control examine design, evaluating people who developed OAG with matched controls who didn’t.
The examine examined statin publicity over two completely different timeframes: 12 months (Mannequin 1) and 24 months (Mannequin 2) previous to the analysis of OAG.5 The researchers discovered no vital affiliation between statin use and the event of OAG in both mannequin. Nonetheless, different research have advised that longer-term statin use is related to an elevated threat of glaucoma.
For example, a 10-year cohort examine carried out in Australia investigated the long-term results of statin use on glaucoma onset.6 This examine used knowledge from a big cohort of Australians aged over 45 and examined medicine use by pharmaceutical claims information between 2009 and 2016.
This analysis differed from the beforehand mentioned Japanese examine by specializing in an extended follow-up interval and a unique inhabitants. The researchers outlined glaucoma onset as three or extra claims for anti-glaucoma medicines.
They then in contrast these people with matched controls who had not been prescribed such medicines. The examine discovered that whereas total statin use was not considerably related to glaucoma onset, a unique image emerged when trying on the period of use.
Particularly, the Australian examine discovered that people who had used statins for greater than three years had a 12% increased threat of creating glaucoma in comparison with those that had used them for lower than one yr.7 This discovering means that the chance of glaucoma related to statins might grow to be extra obvious with longer-term use.
Common eye exams are essential for detecting glaucoma early. As a result of the early phases of open-angle glaucoma are sometimes symptom-free, a complete eye examination is one of the best ways to catch it earlier than vital injury happens.
Throughout an examination, an eye fixed physician measures your IOP, examines your optic nerve and performs different assessments to evaluate your eye well being. Early detection is essential to managing glaucoma and preserving your imaginative and prescient, nonetheless avoiding pointless statin utilization can be essential.
A Broader Take a look at Statin Dangers
Whereas this text focuses totally on the hyperlink between statins and glaucoma, it is essential to acknowledge different unintended effects related to these medicines. Some people taking statins expertise muscle ache or weak point, a situation referred to as myopathy. These muscular points are thought to stem from mitochondrial dysfunction and alterations in muscle protein metabolism.
Statins are additionally linked to an elevated threat of Kind 2 diabetes, cataracts, neurological points and CoQ10 depletion. For example, a 2024 Lancet examine confirmed that statins improve diabetes threat, with high-intensity statins elevating the chance by 36%.8
Additional, statins improve cataract threat by interfering with ldl cholesterol biosynthesis within the lens epithelium. One examine discovered that 1.9% of sufferers underwent cataract surgical procedure throughout a three-year follow-up interval.9
Notably, rosuvastatin was related to a 1% increased incidence of cataract surgical procedure in comparison with atorvastatin, probably as a result of its higher LDL cholesterol-lowering capability. This means that stronger statins like rosuvastatin carry an elevated threat of cataract formation.
As well as, statins are related to an elevated threat of hemorrhagic stroke,10 whereas analysis revealed in Scientific Studies additionally discovered a big affiliation between long-term use of anticholesterol medicine (primarily statins) and an elevated threat of pancreatic most cancers.11 This impact was significantly pronounced in people who had been utilizing these medicine for greater than 5 years.
Additional, as talked about, statin use depletes CoQ10, so, for people taking statins, supplementing with CoQ10 or its extra bioavailable kind, ubiquinol, is essential. The advisable dosage varies from 100 to 200 milligrams (mg) every day for statin customers to 30 mg to 1,200 mg for others, relying on well being standing and way of life elements. Seek the advice of along with your well being care supplier to find out the suitable dosage.
Ldl cholesterol Is Your Physique’s Important Constructing Block
Earlier than deciding to take statin medicine to decrease ldl cholesterol, it is essential to know that ldl cholesterol is definitely an important substance in your physique. Consider ldl cholesterol like tiny constructing blocks. They assist kind the partitions of your cells, maintaining them sturdy and versatile.
Ldl cholesterol additionally helps make hormones your physique wants, and it even performs a task in creating vitamin D from daylight, which retains your bones sturdy and your immune system wholesome.

Insulin resistance results in a decline in your mitochondrial vitality manufacturing, and this poor mitochondrial well being underlies coronary heart illness and lots of different continual circumstances.
Dietary elements, significantly the extreme consumption of linoleic acid (LA) in seed oils, are additionally intricately concerned. The first cause why extra LA is dangerous to your well being is as a result of it disrupts your mitochondria — the tiny vitality factories in your cells that produce adenosine triphosphate (ATP), the important gas that retains your cells working and repairing themselves.
With out vitality, your cells cannot restore and regenerate themselves. So, the basic situation underlying most continual illness is that your cells are usually not producing sufficient vitality.
Along with LA, publicity to artificial endocrine-disrupting chemical substances (EDCs), estrogen and pervasive electromagnetic fields (EMFs) additionally impair your cells’ capacity to generate vitality effectively. This vitality deficit makes it difficult to maintain the oxygen-free intestine atmosphere needed for useful micro organism like Akkermansia to flourish.
In the meantime, your intestine microbiome considerably impacts levels of cholesterol, however a scarcity of mobile vitality creates an atmosphere in your intestine that favors endotoxin-producing micro organism, additional damaging mitochondria, triggering insulin resistance and making a vicious cycle of worsening well being.
By tackling the “4 E’s” — extra LA, estrogens (xenoestrogens present in on a regular basis objects like plastic), EMFs and endotoxins — you restore your mobile vitality and begin down the trail towards optimum well being.
Moreover, make sure you get high quality sleep and successfully handle stress, as each play vital roles in your cardiovascular well being.
