Number of Conditions: 6

Amblyopia (Lazy Eye)

Specialty: Ophthalmology

Category: Congenital or Genetic Conditions

Symptoms:
poor vision in one eye; difficulty focusing

Root Cause:
Poor vision in one eye due to developmental issues during childhood.

How it's Diagnosed: videos
Visual acuity tests revealing a difference between eyes.

Treatment:
Patching the stronger eye, corrective lenses, and vision therapy.

Medications:
No medications; patching or atropine drops (to blur vision in the dominant eye).

Prevalence: How common the health condition is within a specific population.
Affects 2–3% of children; most common cause of vision loss in one eye.

Risk Factors: Factors or behaviors that increase the likelihood of developing the condition.
Strabismus, significant refractive error, deprivation (e.g., cataracts).

Prognosis: The expected outcome or course of the condition over time.
Good if treated early; poor outcomes if untreated.

Complications: Additional problems or conditions that may arise as a result of the original condition.
Permanent vision loss in the affected eye.

Usher Syndrome

Specialty: Ophthalmology

Category: Congenital or Genetic Conditions

Symptoms:
hearing loss; night blindness; peripheral vision loss

Root Cause:
Genetic disorder causing progressive vision and hearing loss.

How it's Diagnosed: videos
Genetic testing, audiology tests, retinal exams.

Treatment:
No cure; hearing aids, cochlear implants, low vision aids.

Medications:
No specific medications; management includes cochlear implants and low-vision aids.

Prevalence: How common the health condition is within a specific population.
Rare; affects 4–17 per 100,000 people globally.

Risk Factors: Factors or behaviors that increase the likelihood of developing the condition.
Autosomal recessive inheritance, consanguineous relationships.

Prognosis: The expected outcome or course of the condition over time.
Progressive vision and hearing loss; management focuses on slowing progression.

Complications: Additional problems or conditions that may arise as a result of the original condition.
Complete blindness and deafness in advanced stages.

Aniridia

Specialty: Ophthalmology

Category: Congenital or Genetic Conditions

Symptoms:
absence of iris; light sensitivity; blurry vision

Root Cause:
A congenital condition causing partial or complete absence of the iris.

How it's Diagnosed: videos
Clinical observation, genetic testing.

Treatment:
Tinted lenses, manage associated conditions (e.g., glaucoma, cataracts).

Medications:
No specific medications; artificial iris implants and lubricating eye drops for dry eye.

Prevalence: How common the health condition is within a specific population.
Rare; affects 1 in 50,000–100,000 people worldwide.

Risk Factors: Factors or behaviors that increase the likelihood of developing the condition.
Genetic mutations in the PAX6 gene.

Prognosis: The expected outcome or course of the condition over time.
Life-long condition; management can mitigate complications.

Complications: Additional problems or conditions that may arise as a result of the original condition.
Glaucoma, cataracts, corneal opacification.

Coloboma

Specialty: Ophthalmology

Category: Congenital or Genetic Conditions

Symptoms:
keyhole-shaped defect in iris or retina; vision impairment

Root Cause:
A developmental defect results in gaps in the iris, retina, or optic nerve.

How it's Diagnosed: videos
Eye examination, imaging studies.

Treatment:
Cosmetic contact lenses, surgery in severe cases.

Medications:
No specific medications; supportive treatments such as low-vision aids.

Prevalence: How common the health condition is within a specific population.
Rare; occurs in about 1 in 10,000 births.

Risk Factors: Factors or behaviors that increase the likelihood of developing the condition.
Congenital malformations, genetic syndromes.

Prognosis: The expected outcome or course of the condition over time.
Depends on the extent of the defect; vision can be preserved in mild cases.

Complications: Additional problems or conditions that may arise as a result of the original condition.
Vision impairment, retinal detachment.

Microphthalmia

Specialty: Ophthalmology

Category: Congenital or Genetic Conditions

Symptoms:
abnormally small eyes; vision impairment

Root Cause:
A congenital condition where one or both eyes are underdeveloped.

How it's Diagnosed: videos
Clinical evaluation, imaging.

Treatment:
Prosthetic eyes for cosmetic appearance, low-vision therapy.

Medications:
No specific medications; prosthetic treatments and low-vision aids.

Prevalence: How common the health condition is within a specific population.
Rare; occurs in approximately 1 in 10,000 births worldwide.

Risk Factors: Factors or behaviors that increase the likelihood of developing the condition.
Genetic mutations, maternal infections during pregnancy (e.g., rubella, toxoplasmosis).

Prognosis: The expected outcome or course of the condition over time.
Vision depends on the severity; prosthetic eyes are often required for cosmetic purposes.

Complications: Additional problems or conditions that may arise as a result of the original condition.
Vision impairment or blindness, associated structural abnormalities.

Leber Congenital Amaurosis

Specialty: Ophthalmology

Category: Congenital or Genetic Conditions

Symptoms:
severe vision loss; blindness at birth

Root Cause:
A genetic disorder severely affects the retina’s ability to detect light.

How it's Diagnosed: videos
Electroretinography, genetic testing.

Treatment:
Gene therapy (Voretigene neparvovec), vision rehabilitation.

Medications:
Gene therapy (e.g., Voretigene neparvovec ).

Prevalence: How common the health condition is within a specific population.
Rare; affects 2–3 per 100,000 people worldwide.

Risk Factors: Factors or behaviors that increase the likelihood of developing the condition.
Genetic mutations, autosomal recessive inheritance.

Prognosis: The expected outcome or course of the condition over time.
Severe vision loss from birth; recent gene therapies have shown promising results.

Complications: Additional problems or conditions that may arise as a result of the original condition.
Nystagmus, light sensitivity, total blindness.
