Types of Morphological Cataracts

 Types of Morphological Cataracts 


Types of Morphological Cataracts refer to the classification of cataracts based on the appearance and location of lens opacity within the eye. Here are the main types:


1. Nuclear Cataract


Location: Center (nucleus) of the lens

Appearance: Yellow or brown discoloration

Features: Gradual vision loss, better near vision ("second sight")


2. Cortical Cataract


Location: Peripheral (outer) part of the lens (cortex)

Appearance: Spoke-like white opacitie 

Features: Glare and difficulty seeing at night


3. Posterior Subcapsular Cataract (PSC)










Location: Back of the lens, just beneath the capsule

Appearance: Small, granular opacity at the back

Features: Glare in bright light, difficulty reading, fast progression


4. Anterior Subcapsular Cataract



Location: Beneath the front (anterior) lens capsule

Appearance: Flat or plaque-like opacity

Features: Less common, associated with trauma or inflammation


5. Polar Cataract






Location: At the front (anterior polar) or back (posterior polar) pole of the lens

Appearance: Well-defined central opacity

Features: Congenital or hereditary, can affect vision significantly


6. Mature Cataract


Appearance: Entire lens is white and opaque

Features: Complete vision loss in the affected eye


7. Hypermature (Morgagnian) Cataract









Appearance: Liquefied cortex, sunken nucleus

Features: Can cause inflammation (phacolytic glaucoma.

MYOPIA

What is Myopia? Myopia (commonly called nearsightedness) is a vision condition where a person can see nearby objects clearly but distant objects appear blurry. What Causes Myopia? It usually occurs when: The eyeball is too long from front to back. The cornea (the clear front surface of the eye) is too curved. As a result, light rays focus in front of the retina, instead of directly on it. Symptoms of Myopia: Blurred vision when looking at distant objects. Squinting to see clearly. Eye strain or headaches (especially after focusing on distant objects). Difficulty seeing while driving, especially at night (night myopia). Risk Factors: Genetics : If one or both parents are myopic, the risk increases. Excessive near work : Prolonged reading, computer, or phone use. Lack of outdoor time: Spending less time in natural light, especially in childhood. Treatment and Management Corrective Lenses: Eyeglasses or contact lenses with minus (–) power lenses. Refractive Surgery: LASIK, PRK, SMILE – re...

Important of colour check

  Why is it important to check colour vision? Checking colour vision is important for several reasons: 1. Early Detection of Vision Disorders It helps detect congenital colour blindness, especially in children. Can also reveal acquired conditions due to eye diseases (e.g., glaucoma, optic neuritis). 2. Career Requirement Certain professions require normal colour vision, such as: Pilots Electricians Military personnel Police officers Graphic designers Drivers Railway and maritime workers 3. Safety and Daily Functioning Correct colour recognition is vital for identifying traffic lights, warning signs, and colour-coded materials. Difficulty distinguishing colours can impact school performance, cooking, clothing choices, and reading charts or graphs. 4. Monitoring Disease Progression Colour vision testing helps track changes in patients with: Diabetic retinopathy Multiple sclerosis Macular degeneration Medication side effects (e.g., ethambutol) 5. Educational Guidance In children, dete...
