An educational intervention to improve adherence to high-dosage patching regimen for amblyopia: a randomised
The British Journal of Ophthalmology
|March 12, 2014
Summary
An educational intervention significantly improved patching adherence for amblyopia treatment in children. However, this enhanced adherence did not lead to better visual outcomes after 12 weeks.
Area of Science:
- Ophthalmology
- Pediatric Medicine
- Clinical Trials
Background:
- Amblyopia treatment adherence is a significant challenge.
- High-dose patching regimens require consistent patient compliance.
- Previous studies indicate adherence issues in patching therapy.
Purpose of the Study:
- To evaluate the effectiveness of an educational intervention on patching adherence in children with amblyopia.
- To determine if improved adherence translates to better visual outcomes.
Main Methods:
- A randomized controlled trial involving 62 children with newly diagnosed amblyopia.
- Intervention group received educational materials and a dedicated session; control group received standard information.
- Both groups were prescribed 10 hours/day, 6 days/week patching for 12 weeks.
- Adherence measured by electronic occlusion dose monitors; visual outcome assessed as percentage visual deficit.
Main Results:
- The intervention group showed a significantly higher adherence success rate (80.6%) compared to the control group (45.2%) (p=0.0027).
- No statistically significant difference in visual outcome was observed between the intervention and control groups (p=0.190).
Conclusions:
- Intensive educational/motivational interventions can substantially improve adherence to prescribed high-dose patching in amblyopia.
- Despite improved adherence, this intervention did not yield a significant improvement in visual outcomes.
- Further research may be needed to correlate adherence levels with visual acuity gains in amblyopia therapy.

Blinding is a commonly used method of not telling participants which treatment a subject is receiving. Blinding is a critical part of a randomized control trial or RCT. It reduces the bias that affects the results. In an RCT, blinding is used in the form of a placebo. A placebo effect occurs when untreated subjects falsely believe they have received the treatment and report improved symptoms. A placebo or a dummy treatment is administered to subjects to negate the bias caused by such an effect.

Ideally, the people who observe and record the children’s behavior are unaware of who was assigned to the experimental or control group, in order to control for experimenter bias. Experimenter bias refers to the possibility that a researcher’s expectations might skew the results of the study. Remember, conducting an experiment requires a lot of planning, and the people involved in the research project have a vested interest in supporting their hypotheses. If the observers knew which...

01:27Open Angle Glaucoma: Treatment
1.1K
In open-angle glaucoma, the iridocorneal angle remains open, but the trabecular meshwork becomes stiff, slowing down the outflow of aqueous humor. This causes a buildup of aqueous humor in the anterior chamber, leading to a sudden increase in intraocular pressure. The treatment for open-angle glaucoma focuses on reducing the elevated intraocular pressure by either decreasing the secretion of aqueous humor or increasing its outflow.

Ophthalmic drug delivery faces major limitations due to poor absorption across the corneal membrane. This process is primarily driven by diffusion and is influenced by two main factors: the physicochemical properties of the drug and tear drainage. Most ophthalmic drugs, such as pilocarpine, epinephrine, atropine, and local anesthetics, are weak bases. They are typically formulated at an acidic pH to enhance chemical stability. However, this leads to high ionization, reducing their ability to...

01:28Angle Closure Glaucoma: Treatment
1.6K
Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...
