Diseases of the Choroid

 Diseases of the Choroid


The choroid is the vascular layer of the eye between the retina and the sclera. It supplies oxygen and nutrients to the outer retina. Diseases affecting the choroid are called choroidopathies or choroidal diseases.


🔹 Common Choroidal Diseases:


1. Choroiditis


  • Inflammation of the choroid.

  • Can be caused by infections (e.g., tuberculosis, toxoplasmosis) or autoimmune conditions.

Symptoms: Blurred vision, floaters, eye pain (sometimes).


2. Choroidal Neovascularization (CNV)


  • Abnormal blood vessels grow from the choroid into the retina.

  • Common in age-related macular degeneration (AMD).


Symptoms: Distorted vision, central vision loss.


3. Central Serous Chorioretinopathy (CSCR)




  • Fluid leaks from choroid under the retina, forming a blister-like elevation.


Symptoms: Blurred central vision, dark spots, image distortion.


4. Choroidal Melanoma


  • A rare cancer of the eye arising from the choroid’s melanocytes.

  • May not cause early symptoms, but can lead to vision loss or eye bulging.


5. Choroidal Detachment


  • Separation of the choroid from the sclera due to fluid or blood accumulation.


Causes: Trauma, surgery, inflammation.


6. Choroidal Hemangioma


Benign vascular tumor in the choroid.

May cause blurred vision if it affects the retina.


🔍 Symptoms 

  • Sudden vision loss

  • Distorted or blurred vision
  •  Floaters or flashes

  • Dark spots in the visual field


✅ Diagnosis:


  • Fundus examination

  • Optical Coherence Tomography (OCT)

  • Fluorescein angiography

  • Ultrasonography (in tumors or detachments)


💊 Treatment:

  1. Depends on the cause


  • Infections: Antibiotics or antivirals

  • Inflammation: Steroids or immunosuppressants

CNV: Anti-VEGF injections

Tumors: Laser, radiation, or surgery

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...
