Common Eye Diseases

Understanding Eye Health

Cataract

Cataract

Cataract is a clouding of the lens in the eye, leading to a decrease in vision. It is common in older adults, but can also occur due to injury, diabetes, or prolonged use of certain medications.

Symptoms:
  • Blurred or cloudy vision
  • Difficulty seeing at night
  • Colors appear faded
Treatment:

Surgical removal of the cataract and replacement with an artificial lens.

Glaucoma

Glaucoma

Glaucoma is a group of eye diseases that damage the optic nerve, often due to high intraocular pressure, leading to gradual vision loss if untreated.

Symptoms:
  • Loss of peripheral vision
  • Halos around lights
  • Redness in the eye
Treatment:

Medications (eye drops) or surgery to lower intraocular pressure.

Macular

Age-Related Macular Degeneration (AMD)

AMD is a leading cause of vision loss in people over 50, causing damage to the central part of the retina (macula), affecting sharp, central vision.

Symptoms:
  • Blurry or distorted central vision
  • Difficulty recognizing faces
  • Need for brighter light when reading
Treatment:

Laser therapy, injections into the eye, or photodynamic therapy for advanced cases.

Retinopathy

Diabetic Retinopathy

Diabetic retinopathy is a complication of diabetes where high blood sugar damages the blood vessels of the retina, leading to vision impairment or blindness.

Symptoms:
  • Blurred vision
  • Floaters or dark spots in vision
  • Vision loss
Treatment:

Laser treatments, injections of medication, and vitrectomy surgery.

Conjunctivitis

Conjunctivitis (Pink Eye)

Conjunctivitis is the inflammation of the conjunctiva, often caused by infection (bacterial or viral) or allergens. It is highly contagious.

Symptoms:
  • Redness in the eye
  • Itching or burning sensation
  • Watery eyes or discharge
Treatment:

Antibiotics (for bacterial), antiviral treatment (for viral), or antihistamines (for allergies).

Retinal

Retinal Detachment

Retinal detachment occurs when the retina pulls away from its normal position, causing severe vision problems. It is a medical emergency that requires immediate treatment.

Symptoms:
  • Flashes of light
  • Sudden appearance of floaters
  • Partial loss of vision or a shadow over the vision
Treatment:

Surgery or laser treatment to reattach the retina.
