Condition Lookup

Number of Conditions: 2

Night Blindness (Nyctalopia)

Specialty: Ophthalmology

Category: Vision Impairment and Light Sensitivity

Symptoms:
difficulty seeing in low light

Root Cause:
Poor function of rod cells in the retina limits vision in low-light conditions.

How it's Diagnosed: videos
Clinical evaluation, thyroid function tests, imaging studies.

Treatment:
Treat underlying cause (e.g., Vitamin A deficiency, manage retinitis pigmentosa).

Medications:
Vitamin A supplementation if due to deficiency.

Prevalence: How common the health condition is within a specific population.
Common in people with Vitamin A deficiency or genetic retinal disorders.

Risk Factors: Factors or behaviors that increase the likelihood of developing the condition.
Vitamin A deficiency, retinitis pigmentosa, glaucoma medications.

Prognosis: The expected outcome or course of the condition over time.
Depends on the underlying cause; treatable in cases related to nutritional deficiencies.

Complications: Additional problems or conditions that may arise as a result of the original condition.
Difficulty navigating in low-light conditions, increased risk of falls or accidents.

Photophobia

Specialty: Ophthalmology

Category: Vision Impairment and Light Sensitivity

Symptoms:
light sensitivity; eye pain in bright environments

Root Cause:
Increased sensitivity of the retina or optic nerve to light stimuli.

How it's Diagnosed: videos
Patient history, examination to determine underlying cause.

Treatment:
Protective eyewear, manage underlying conditions (e.g., migraines).

Medications:
Treat underlying cause; lubricating eye drops and tinted lenses.

Prevalence: How common the health condition is within a specific population.
Common as a symptom of many eye conditions or systemic diseases.

Risk Factors: Factors or behaviors that increase the likelihood of developing the condition.
Migraine, meningitis, corneal abrasions, uveitis, albinism.

Prognosis: The expected outcome or course of the condition over time.
Improves with treatment of the underlying cause; may persist in chronic conditions.

Complications: Additional problems or conditions that may arise as a result of the original condition.
Avoidance of bright environments, reduced quality of life.
