Cortical cataract-various-aspects-
Cortical cataracts form when the outer area of your eye lens becomes hazy due to an increase in water and the clumping of proteins. This condition leads to blurred vision and other issues. Surgical intervention can help prevent more severe symptoms, which could potentially result in blindness.
Cortical cataracts initially appear as cloudy lines on the periphery of your lens. They tend to become more prevalent as you age.
Your eye’s lens is located behind the iris and pupil. It is a round, clear structure connected to fine muscles that adjust how your eye focuses. The center of the lens is known as the nucleus, while the outer area is referred to as the lens cortex.
Over fifty percent of individuals in the United States develop cataracts by the time they reach 80 years of age. Cataracts generally progress gradually and can eventually disrupt your vision. Symptoms may include:
- – blurriness in vision
- – challenges seeing at night
- – experiencing double vision
Cataracts remain the primary source of reversible blindness worldwide. In the U. S. , medical professionals can often treat them effectively through surgery that replaces the lens with an artificial one.
Continue reading to discover more about cortical cataracts, their prevalence, and how to manage this eye condition.
What leads to the development of a cortical cataract?
Cataracts occur when the lens becomes opaque due to elevated water levels and protein clumping. When this situation affects the lens cortex, it is classified as a cortical cataract.
The primary factor for this condition is the natural aging process of the eyes. Additional contributors that may heighten your risk of developing cataracts include:
- – having a family background of cataracts
- – suffering from diabetes
- – experiencing an eye injury
- – using corticosteroids
- – receiving radiation therapy
- – undergoing eye surgery for glaucoma or other issues
Factors that could accelerate cataract formation include:
- – smoking habits
- – excessive alcohol intake
- – regular exposure to sunlight, particularly without sunglasses

Different types of cataracts
Experts categorize cataracts based on the location of their development within the lens:
- – Nuclear cataracts: These cataracts arise in the center of the lens, known as the nucleus.
- – Cortical cataracts: These occur in the outer area of the lens, called the cortex.
- – Subcapsular cataracts: These develop on the back side of the lens.
A cortical cataract typically starts as a wedge-shaped section or streaks of cloudiness along the lens’s edge. As it advances, it can spread to the center of the lens. Cortical cataracts may progress rapidly or slowly and can appear alone or alongside nuclear cataracts.
Risk factors
Research from 2017 indicates that individuals with nearsightedness have a reduced risk of developing cortical cataracts compared to nuclear ones. Conversely, those who are farsighted appear to have a higher likelihood of developing cortical cataracts over nuclear types.
A 2019 study examined cortical cataracts in 239 individuals aged 50 to 90 who were preparing for cataract surgery. Its findings showed cortical cataracts in:
- – 37% of nearsighted individuals
- – 82% of average-vision individuals
- – 85% of farsighted individuals
A 2020 study conducted in Singapore discovered that certain medications were linked to the presence of cortical cataracts.
- ACE inhibitors
- fibrates
- alpha-glucosidase inhibitors

What is the prevalence of cortical cataracts?
Cataracts are widespread, impacting over 24 million individuals in the United States. Among these, cortical cataracts represent approximately 22. 9% of all age-related cataracts.
The likelihood of developing age-related cortical cataracts may rise due to factors such as ultraviolet light exposure and elevated blood sugar levels. Research indicates that genetic influences account for 53% to 75% of the risk associated with cortical cataracts.
What do vision changes look like when experiencing cortical cataracts?
Cortical cataracts that form on the edges of your lens may not initially affect your eyesight. However, as these cataracts advance, they can move into your central vision, obstructing the light that enters your eyes. This can lead to various symptoms, such as:
- fuzzy or doubled vision
- glare or halos surrounding light sources
- brighter points of light noticed especially at night
- challenges with distinguishing colors, assessing depth, and focusing on near objects
How fast do cortical cataracts develop?
Generally, cataracts related to aging tend to progress gradually over many years, though some individuals may experience a quicker development.
Those with diabetes tend to see a faster progression of cataractsTrusted Source. Proper control of diabetes, as well as managing high blood pressure and cholesterol levels, may help slow down the advancement of cataracts.
Is surgery necessary for cortical cataracts?
If cortical cataracts begin to interfere with your vision, surgical intervention might be necessary. This procedure involves substituting your natural lens with an artificial one. Cataract surgery is recognized as one of the safest procedures Trusted Source performed by health professionals in the United States, and it often yields excellent results.
What are the consequences of leaving cataracts untreated?
Cataracts are progressive in nature. Seeking treatment can help halt any further decline in your vision. If left untreated, mature cataracts can leak degraded proteins into the eye, raise the pressure inside the eye, and trigger a severe inflammatory response.
The speed at which cataracts develop can differ significantly from person to person, but without surgery, they have the potential to result in legal blindness or total blindness.
Cortical cataracts can alter your vision, resulting in issues like blurriness or double vision if they encroach on your central visual field. Presently, surgery is the only available treatment for cataracts, and it is typically very safe and effective.
