Retinal diseases

 Retinal diseases 

Retinal diseases are conditions that affect the retina, the light-sensitive tissue lining the back of the eye responsible for capturing images and sending visual signals to the brain. Damage to the retina can lead to vision impairment or blindness if not treated promptly.


Common Retinal Diseases


1. Diabetic Retinopathy













Caused by damage to retinal blood vessels due to diabetes.

Symptoms: Blurred vision, floaters, vision loss in advanced stages.


2. Retinal Detachment









Retina separates from the underlying tissue.

Symptoms: Sudden flashes of light, floaters, curtain-like shadow over vision.

Medical emergency.


3. Age-Related Macular Degeneration (AMD)












Affects the macula, responsible for sharp central vision.


Types: Dry AMD (gradual) and Wet AMD (sudden due to bleeding).

Symptoms: Difficulty reading, recognizing faces, central vision loss.


4. Retinitis Pigmentosa (RP)









A group of genetic disorders causing gradual retinal degeneration.

Symptoms: Night blindness, tunnel vision, progressive vision loss.


5. Macular Hole









A small break in the macula.

Symptoms: Distorted central vision, blurry spot in the center.


6. Retinal Vein or Artery Occlusion




Blockage in retinal blood vessels.

Symptoms: Sudden, painless vision loss in one eye.


7. Cytomegalovirus (CMV) Retinitis


Occurs in people with weakened immune systems.

Symptoms: Blurred vision, floaters, blind spots.


Symptoms to Watch For

  • Sudden or gradual vision loss

  • Flashing lights or floaters

  • Distorted or blurred vision

  • Dark spots or curtain-like shadow in vision


Treatment Options


Laser therapy – for diabetic retinopathy or retinal tears

Injections (Anti-VEGF drugs) – for wet AMD or retinal swelling

Surgery (Vitrectomy) – for retinal detachment or vitreous bleeding

Control of underlying conditions – like diabetes or hypertension

Low vision aids – for irreversible damage

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...
