The Veil on CBD and Cataracts: An Introduction

CBD, or cannabidiol, is rapidly gaining attention as a potential treatment for a variety of health conditions, from chronic pain to anxiety. But can it help with cataracts, the most common cause of vision loss globally? The World Health Organization cites cataracts as responsible for 51% of global blindness, affecting roughly 20 million people. Cataracts occur when the natural lens of the eye becomes cloudy, causing blurry, foggy, or dim vision. If left untreated, it can lead to vision impairment or even complete vision loss.

With cataract surgery being the only known effective cataract treatment, interest in alternative therapies like CBD is growing. There is ongoing research exploring the potential of CBD for eye health, including its effect on intraocular pressure, a significant risk factor for several eye conditions such as glaucoma and retinal detachment. This article seeks to shine a light on the complex interactions between CBD and cataracts, exploring how CBD may play a role in managing eye conditions.

The Science of Sight: Understanding Cataracts

Cataracts are characterised by the clouding of the eye’s natural lens, which lies behind the iris and the pupil. This clouding occurs when the proteins in the lens clump together, leading to a reduction in the clarity of vision. Various factors contribute to developing cataracts, including age, UV radiation, and chronic diseases such as diabetes and high blood pressure. The National Eye Institute categorises cataracts into three types: age-related cataracts, congenital cataracts (present at birth), cortical cataracts, and secondary cataracts (due to disease control or medications).

The traditional solution for cataracts has been cataract surgery, which involves removing the cloudy lens and replacing it with an artificial one. While this procedure is generally safe and effective, it is not without risks. Complications can include infection, bleeding, retinal detachment, and increased intraocular pressure.

Enter CBD: A Potential Alternative?

CBD, a primary non-psychoactive compound in the hemp plant, is known for its potential therapeutic properties. Medical cannabis, including CBD oil, has been used for centuries to treat various ailments, from chronic pain to neurologic disorders. Its medicinal properties, particularly its anti-inflammatory and antioxidant capabilities, have made it a promising candidate for managing eye health, including conditions like cataracts.

Several studies have suggested that CBD may help reduce intraocular pressure, a crucial factor in eye conditions such as glaucoma and cataracts. For instance, a study by the American Academy of Ophthalmology found that medical marijuana could lower intraocular pressure by 25-30%. Another study published in the Journal of Glaucoma noted temporary improvement in intraocular pressure lasting three or four hours a few weeks after smoking marijuana.

Delving Deeper: The Endocannabinoid System and Eye Health

To understand the role CBD might play in managing cataracts, it’s crucial to understand the endocannabinoid system (ECS), a complex cell-signalling system within the human body. The ECS regulates various functions such as mood, sleep, and pain, and it’s also thought to play a role in maintaining eye health. It comprises endocannabinoids, enzymes, and cannabinoid receptors (CB1 and CB2), which are found throughout the body.

CB1 receptors are largely found in the central nervous system, including parts of the brain and spinal cord, while CB2 receptors are more often found in the peripheral nervous system and immune cells. Research suggests that CB1 receptors play a crucial role in the regulation of intraocular pressure, thereby affecting conditions like glaucoma and cataracts. A study from the University of Aberdeen found that activation of these CB1 receptors resulted in reduced intraocular pressure.
