[Cycloplegia and residual accommodation (author's transl)].
The cycloplegic effect of 1% Atropine Sulphate, 2% Homatropine Hydrobromide and 1% Cyclopentholate (Cyclolat) were compared on 8 to 10 year-old children with hyperopic accommodation and partial accommodation squint. The objective refraction was measured by skiascopy and with Hartinger's refractometer, and these two values were compared. The distant-vision correction, and also the near-vision correction needed so that Table 2 of Pursch's Tables could be read, were measured. Atropine showed itself to be the most effective cycloplegic agent. With atropine cycloplegia was attained in 46.77% - shown by a necessary near-correction of +2 dioptres, or less. In 27.42% the correction was +1.5 dioptres. With homatropine a correction of +2 dioptres or less occurred in 82.14%, after Cyclogyl in 72.34%. Better cycloplegia could be reached, if before the test correcting spectacles are worn. Only with repeated refraction-tests to overcome accommodation spasm could one succeed in finding the complete hypermetropic state -- even with the help of a not very demanding cycloplegic agent like atropine. Cyclogyl was found to be the most suitable agent here.
