Sensitivity to light is called?

Appeared in: DSSSB - 29 August 2019 (Shift-2)

Explanation

Photophobia is the correct medical term for excessive sensitivity to light.
The prefix 'photo-' relates to light, and '-phobia' in this context means aversion or intolerance, not fear.
It is a common symptom of various conditions affecting the eyes or nervous system, such as migraine, meningitis, or uveitis.
The discomfort can range from mild to severe, causing a person to squint or avoid bright environments, as depicted in the image.

Option B: Polyphagia refers to excessive hunger or an increased appetite.
Option C: Aerophobia is an irrational fear of drafts of air or, more commonly, a fear of flying.
Option D: Polydipsia refers to excessive thirst.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Medical Terminology as background academic context rather than a clinical decision trigger.
Photophobia is a clinically significant symptom that requires careful nursing assessment to identify its underlying cause.
Nursing interventions are focused on patient comfort, such as dimming room lights and providing sunglasses, which can significantly improve the patient's quality of life.
What if? If a patient presents with photophobia, fever, and neck stiffness, a nurse must recognize these as hallmark signs of meningitis and initiate isolation precautions and escalate care immediately, as it is a medical emergency.

How to Approach the Question

First, identify the key phrase in the question: 'Sensitivity to light'.
This is a definition-based question, so the task is to recall the correct medical term.
Break down the options by their prefixes and suffixes. 'Photo-' relates to light.
Evaluate each option: 'Photophobia' combines 'photo' (light) and 'phobia' (aversion/intolerance). 'Polyphagia' and 'Polydipsia' relate to eating and drinking. 'Aerophobia' relates to air.
Based on the word parts, Photophobia is the most logical answer for light sensitivity.
Confirm the definitions of the other terms to ensure they are incorrect.
