Insights
A combination of cyclopentolate and tropicamide offers a viable alternative to atropine for cycloplegic refraction in children with hypermetropia, providing similar results with potentially fewer side effects.
Area of Science:
- Ophthalmology
- Pediatric Ophthalmology
- Optometry
Background:
- Cycloplegic refraction is crucial for diagnosing hypermetropia in children.
- Atropine, while effective, has a prolonged action and significant side effects.
- Shorter-acting cycloplegic agents are preferred for pediatric use.
Purpose of the Study:
- To compare the efficacy of atropine 1% with a combination of cyclopentolate 1% and tropicamide 1% for cycloplegic refraction.
- To evaluate the cycloplegic effect of these agents in children diagnosed with hypermetropia.
Main Methods:
- A crossover interventional study was conducted on 63 children (126 eyes) aged 5-12 years with hypermetropia.
- Two cycloplegic refraction regimens were administered: atropine 1% and cyclopentolate 1% with tropicamide 1%.
- Data were analyzed using SPSS v22.0, with P ≤ 0.05 considered significant.
Main Results:
- No statistically significant difference was found in the mean spherical equivalent values between atropine 1% and the cyclopentolate/tropicamide combination for both right (P=0.59) and left eyes (P=0.56).
- Mean spherical equivalent for the right eye was 4.73 ± 2.1 DS (atropine) vs. 4.54 ± 1.9 DS (combination).
- Mean spherical equivalent for the left eye was 4.74 ± 2.0 DS (atropine) vs. 4.54 ± 1.8 DS (combination).
Conclusions:
- The combination of 1% cyclopentolate and 1% tropicamide is an effective alternative to 1% atropine for cycloplegic refraction in pediatric hypermetropia.
- This combination may offer a more favorable side effect profile compared to atropine.
- Further research could explore long-term outcomes and patient tolerance.
Background:
Cycloplegic refraction is important in assessing children with hypermetropia. Atropine, though the gold standard cycloplegic agent for refraction in children, has a long duration of action and more severe side effects compared to short-acting cycloplegic agents. The aim of the study was to compare the cycloplegic effect of atropine with cyclopentolate and tropicamide combination in children with hypermetropia.
Subjects And Methods:
This was a crossover interventional study in children with hypermetropia. Cycloplegic refraction using two separate regimens of cycloplegic drugs was done on all subjects. Data were analyzed using the statistical software SPSS version 22.0. The mean spherical equivalent values of regimen 1 (atropine 1%) and regimen 2 (cyclopentolate 1% and tropicamide 1%) were presented as mean and standard deviation. A P ≤ 0.05 was considered statistically significant.
Results:
One hundred and twenty-six eyes of 63 subjects aged 5-12 years were examined. The mean spherical equivalent values for regimen 1 and regimen 2 for the right eyes were 4.73 ± 2.1 DS and 4.54 ± 1.9 DS, respectively (P = 0.59). The mean spherical equivalent values for regimens 1 and 2 for the left eyes were 4.74 ± 2.0 DS and 4.54 ± 1.8 DS, respectively (P = 0.56).
Conclusion:
The combination of 1% cyclopentolate and 1% tropicamide could be a useful alternative to atropine 1% for cycloplegic refraction in children with hypermetropia.
