Summary
This study reports on ten young patients experiencing asthenopia due to significantly reduced amplitude of accommodation. Optical management with bifocals or reading glasses proved effective for these accommodation insufficiency cases.
Area of Science:
- Ophthalmology
- Pediatric Optometry
- Vision Science
Background:
- Accommodation insufficiency, characterized by reduced amplitude of accommodation, can cause asthenopia during near visual tasks.
- This condition affects visual performance in reading and other near activities, particularly in younger individuals.
Observation:
- Ten patients aged 10-19 presented with symptoms of asthenopia during near work.
- All patients exhibited an amplitude of accommodation significantly below age-expected norms (average 6 diopters).
- Associated convergence insufficiency was noted in three patients; no clear etiology was identified.
Findings:
- Optical correction using bifocals or reading glasses successfully managed the diminished accommodation in all patients.
- Three patients required additional base-in prisms to correct near exodeviation.
Implications:
- Near vision testing and assessment of the near point of accommodation are crucial components of pediatric ophthalmologic examinations.
- Early identification and optical management can alleviate asthenopia and improve visual performance in young patients with accommodation insufficiency.
