Comparison of Instillation and Packing in Mydriasis for Premature Infants

Preterm Infants Clinical Trial

Official title:
Comparison of Conventional Instillation and Lower Conjunctival Fornix Packing in Mydriasis for Premature Infants

Clinical Trial Summary

The purpose of this study is to compare the mydriatic effect of 2.5% phenylephrine and 1% tropicamide by conventional instillation and lower conjunctival fornix packing in premature infants.

Clinical Trial Description

Adequate pupil dilatation was needed for screening and treatment of retinopathy of prematurity (ROP) in premature infants.In general clinical practice, mydriatic drugs were instilled many times until the pupil reached the maximum size. However, poor mydriasis were found in many eyes despite maximum instillation was used. From the clinical observation, we found the packing of mydriatic drugs in lower conjunctival fornix was much more effective to dilate the pupil than instillation in some patients. The purpose of this study was to compare the mydriatic effect of 2.5% phenylephrine and 1% tropicamide by conventional instillation and lower conjunctival fornix packing in premature infants. ;
