8.1.6 Flashcards
Why is early detection of binocular vision anomalies crucial?
Children may not always report visual disturbances, making routine vision screenings essential.
Who often leads vision screening programs for children aged 4–5 years in the UK?
Orthoptists
What are the key components of a comprehensive assessment for binocular vision anomalies?
Evaluating visual acuity, ocular alignment, and binocular function.
What condition can contribute to strabismus and should be identified during assessments?
Refractive errors
What is the management strategy that involves prescribing appropriate glasses?
Refractive Correction
What is the purpose of occlusion therapy in the management of amblyopia?
Patching the stronger eye encourages use of the weaker eye, improving visual acuity.
What are orthoptic exercises designed to improve?
Binocular function
When might surgical intervention be considered in the management of strabismus?
When non-surgical methods are insufficient.
What role do orthoptists play in hospitals?
They are specialists in diagnosing and managing binocular vision disorders.
What is prism therapy used for?
To alleviate diplopia (double vision) and improve ocular alignment.
What can affect waiting times for orthoptic and ophthalmologic services?
Location and demand.
What is convergence insufficiency (CI)?
A reduced ability of the eyes to turn inward when focusing on a near object.
What are common symptoms of convergence insufficiency?
- Eye strain
- Headaches
- Blurred vision
- Difficulty reading
What is a common exercise for improving convergence ability?
Pencil push-ups
What has research shown about office-based vision therapy for CI?
It is more effective than home-based exercises alone in treating CI in children aged 9 to 18.
What does strabismus refer to?
The misalignment of the eyes.
What are the types of strabismus based on eye position?
- Esotropia (inward)
- Exotropia (outward)
- Upward
- Downward
What is one management option for strabismus that involves glasses?
Refractive correction to correct refractive errors.
What is the purpose of botulinum toxin injection in strabismus treatment?
To temporarily weaken overactive muscles, allowing the eyes to realign.
What is involved in pre- and post-surgical care for strabismus surgery?
Assessment and management to ensure optimal outcomes.
What factors can influence wait times for orthoptic referrals at Royal Alexandra Hospital?
- Demand
- Staffing
- Patient urgency
