What are the other Names for this Condition? (Also known as/Synonyms)

• Back Cataract
• PSC (Posterior Subcapsular Cataract)

What is Posterior Subcapsular Cataract? (Definition/Background Information)

• Posterior Subcapsular Cataract (PSC) is a type of cataract that affects the back of the lens, just beneath its outermost layer called the lens capsule. This type of cataract typically develops more rapidly compared to other forms and can lead to significant visual disturbances, particularly in bright lighting conditions. PSC is often associated with various factors, including age, diabetes, long-term steroid use, and certain eye conditions
• The signs and symptoms of Posterior Subcapsular Cataract include blurred or hazy vision, glare sensitivity, and difficulty with night vision. The cataract's location at the back of the lens often leads to increased sensitivity to bright lights, causing discomfort and reduced visual clarity
• Diagnosing Posterior Subcapsular Cataract involves a comprehensive eye examination, including visual acuity tests, pupil dilation, and a slit-lamp examination. The distinctive location of the cataract within the posterior subcapsular area can be observed, confirming its presence
• In the early stages of Posterior Subcapsular Cataract, wearing anti-glare sunglasses and using corrective eyewear might help alleviate symptoms. However, as the cataract progresses and impacts daily activities, surgical intervention is often necessary. Cataract surgery involves removing the clouded lens and replacing it with an artificial intraocular lens (IOL) to restore clear vision
• The prognosis for individuals undergoing cataract surgery for Posterior Subcapsular Cataracts is generally positive. Cataract surgery is highly successful in restoring clear vision and reducing glare sensitivity. Patients usually experience improved visual acuity and enhanced quality of life after the procedure

Who gets Posterior Subcapsular Cataract? (Age and Sex Distribution)

• Posterior Subcapsular Cataracts are more commonly seen in individuals with diabetes, those who have used long-term steroids, and those with certain eye conditions
• While they can develop at any age, they are often associated with adults
• The condition is observed across all racial and ethnic groups worldwide

What are the Risk Factors for Posterior Subcapsular Cataract? (Predisposing Factors)

The risk factors for Posterior Subcapsular Cataract include the following:

• Diabetes
• Prolonged use of steroids
• Certain eye conditions like uveitis
• Trauma
• Advanced age

It is important to note that having a risk factor does not mean that one will get the condition. A risk factor increases one’s chances of getting a condition compared to an individual without the risk factors. Some risk factors are more important than others.

Also, not having a risk factor does not mean that an individual will not get the condition. It is always important to discuss the effect of risk factors with your healthcare provider.

What are the Causes of Posterior Subcapsular Cataract? (Etiology)

• The exact causes of Posterior Subcapsular Cataract are not entirely understood
• It is thought to be related to changes in the lens proteins and metabolism, particularly in response to factors like diabetes and steroid use

What are the Signs and Symptoms of Posterior Subcapsular Cataract?

The signs and symptoms of Posterior Subcapsular Cataract may encompass the following:

• Blurred or hazy vision
• Increased glare sensitivity
• Difficulty with night vision
• Vision impairment may be rapidly progressive
• Individuals with near vision may face more challenges than those with distance vision
• The cataract's location at the back of the lens can cause discomfort in bright lighting conditions

How is Posterior Subcapsular Cataract Diagnosed?

The diagnosis of Posterior Subcapsular Cataract may involve the following tests and exams:

• Physical examination and medical history evaluation
• Comprehensive eye examination by an ophthalmologist
• Visual acuity tests
• Pupil dilation (fundus examination)
• Slit-lamp examination

The distinct location of the cataract within the posterior subcapsular area aids in its identification.

Many clinical conditions may have similar signs and symptoms. Your healthcare provider may perform additional tests to rule out other clinical conditions to arrive at a definitive diagnosis.

What are the possible Complications of Posterior Subcapsular Cataract?

The complications of Posterior Subcapsular Cataracts include:

• Worsening visual disturbances
• Increased discomfort in bright light
• Potential limitations in daily activities

How is Posterior Subcapsular Cataract Treated?

The treatment options for Posterior Subcapsular Cataracts may range from:

• Wearing anti-glare sunglasses and corrective eyewear in the early stages
• Surgical removal of the cataract with intraocular lens implantation for improved vision in more advanced cases

How can Posterior Subcapsular Cataract be Prevented?

While prevention might not be possible in all cases of Posterior Subcapsular Cataracts, the following measures may be considered:

• Managing underlying conditions like diabetes and minimizing steroid use can potentially reduce the risk
• Protecting the eyes from excessive sunlight exposure is also beneficial

What is the Prognosis of Posterior Subcapsular Cataract? (Outcomes/Resolutions)

• The prognosis for individuals undergoing cataract surgery for Posterior Subcapsular Cataracts is generally favorable
• Cataract surgery is successful in restoring clear vision and reducing glare sensitivity, leading to improved quality of life

Additional and Relevant Useful Information for Posterior Subcapsular Cataract:

• A cataract is defined as opacification (to become opaque) or clouding of the natural clear lens that results in visual problems, including blindness
