cycloplegia
LowTechnical/Medical
Definition
Meaning
A temporary paralysis of the ciliary muscle of the eye, which controls the lens's ability to focus.
A clinical condition intentionally induced during an eye examination to completely relax accommodation, allowing for an accurate measurement of refractive error.
Linguistics
Semantic Notes
This term is strictly medical/ophthalmological. It is a state, not a disease process, and is typically the result of pharmacological intervention.

Examples
By Part of Speech
verb
British English
- The optometrist will cycloplege the paediatric patient prior to retinoscopy.
American English
- The ophthalmologist cyclopleged the child's eyes for a thorough exam.
adjective
British English
- A cycloplegic agent is essential for an accurate refraction in children.
American English
- The cycloplegic drops will cause blurry near vision for hours.
Examples
By CEFR Level
- The doctor put drops in my eyes and I couldn't see close things clearly.
- For a precise glasses prescription in children, doctors often use special eye drops to relax the focusing muscle.
- The ophthalmologist induced cycloplegia to ensure the child's latent hyperopia was fully revealed during the examination.
- The study compared refractive error measurements with and without pharmacological cycloplegia in young adults, finding significant differences in a subset of patients.
Learning
Memory Aids
Mnemonic
"CYCLE + PLEGIA (paralysis). Think of the 'cycle' of focusing your eye being 'paralyzed' or stopped."
Conceptual Metaphor
A temporary disabling of the eye's internal autofocus mechanism.

Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid translating as 'циклоплегия' unless in a strict medical context; there is no everyday equivalent.
- Do not confuse with 'мидриаз' (mydriasis, pupil dilation), which often accompanies but is distinct from cycloplegia.
Common Mistakes
- Mispronouncing as 'psychoplegia' or 'cyclo-plee-ja'.
- Using it to refer to simple pupil dilation.
- Spelling as 'cycloplegia'.

FAQ
Frequently Asked Questions
No. Cycloplegia specifically paralyzes the ciliary muscle for focusing. Pupil dilation (mydriasis) is a separate effect often caused by the same drugs, but they are distinct processes.
It depends on the drug used. Short-acting agents like cyclopentolate may last 6-24 hours, while long-acting ones like atropine can last up to two weeks.
Primarily children and young adults, whose eyes have a strong ability to focus and can therefore mask true refractive errors like hyperopia (farsightedness).
The procedure itself is not painful (just eye drops), but the temporary loss of near vision and sensitivity to light can be inconvenient. It is a standard, safe procedure when performed correctly.
