E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To compare one dose of the short acting tropicamide combined with one dose of the longer acting cyclopentolate (c+t) with a double dose of the longer acting cyclopentolate (c+c)
Primary outcomes •Detection of statistical or clinical significant- or no difference in depth of cycloplegia; e.g. residual accommodation, between c+c and c+t.
•Detection of statistical or clinical significant- or no difference in recuperation time of 1) ciliary paralysis and 2) sphincter paralysis between c+c and c+t.
|
|
E.2.2 | Secondary objectives of the trial |
•Detection of statistical or clinical significant- or no difference in time of stability of maximum cycloplegia between c+c and c+t.
•Detection of statistical or clinical significant- or no difference in 1) depth of cycloplegia 2)in time to maximum cycloplegia 3) in time of stability of maximum cycloplegia between eye-colour main groups in c+c and c+t.
•Identification of factors that affect 1) depth of cycloplegia 2) time of stability of maximum cycloplegia 3) recuperation time from ciliary and sphincter paralysis in c+c and c+t.
•Detection of statistical or clinical significant or no differences in changes in astigmatism during the time course of cycloplegia in c+c and c+t. •Establishment of a statistical significant or no relationship between incomplete cycloplegia and changes in astigmatism in c+c and c+t. •Detection of statistical or clinical significant- or no differences in astigmatism between relaxed and demanding accommodation circumstances in c+c and c+t.

E.2.3 | Trial contains a sub-study | Yes |
E.2.3.1 | Full title, date and version of each sub-study and their related objectives |
This investigator initiated study is designed as a prospective, single-centre, cross sectional, quantitative, randomized double blind trial with repeated measurements.
The study is divided in three parts. Part I measures residual accommodation; e.g. depth of cycloplegia and stability of (complete) cycloplegia in time. Part II measures (monitors) recuperation of ciliary paralysis in time and part III measures (monitors) recuperation of spincter paralysis in time.

E.3 | Principal inclusion criteria |
Patient is considered for the study when: • Good general health • Age 7 to 13 years o Group 4 - 8 of the Dutch primairy school system Part I and II • Hypermetropia; e.g. > 0. 50 diopters in spherical equivalence (SEQ) values* • Good accommodation; e.q. > 10 diopters with dynamic retinoscopy • Sufficient reading capabilities • Best corrected distance visual acuity (BCDVA) of > 0.7 in each eye • Best corrected near visual acuity (BCNVA) of > 1.0 in each eye Part III • Emmetropia or myopia in SEQ values • Isocoria and normal pupillary responses
* SEQ= sphere + cylinder:2 |
|
E.4 | Principal exclusion criteria |
• Not healthy • Aged <6 and >13 year • Attending group 3 of the Dutch school system • Attending secondary school Part I and II • Refractive errors < +0.50 • Best corrected visual acuity of < 0.7 in one or both eye’s • Insufficient reading capabilities • Insufficient accommodation Part III • Emmetropia or hypermetropia • An-isocoria or abnormal pupillary responses

E.5 End points |
E.5.1 | Primary end point(s) |
Part I Primary outcome parameter is residual accommodation; e.g. depth of cycloplegia. Secondary outcome parameter are time of stability of (maximum) cycloplegia and changes in astigmatism. Differences will be considered statistical significant if p<0.05. A difference in residual accommodation of > 0.50 D, a time difference in stability of > 10 minutes, and a change of > 0.50 D cylinder or a change of >5° cylinder ax will be considered clinical significant.
Part II Primary outcome parameter is time to recuperation of ciliary paralyses. Differences will be considered statistical significant if p<0.05. A difference in recuperation time of > 2 hours will be considered clinical significant.
Part III Primary outcome parameter is time to recuperation of sphincter paralyses. Differences will be considered statistical significant if p<0.05. A difference in recuperation time of > 2 hours will be considered clinical significant.
