Abstract :

Title: Cotton pledget soaked in single drop of Tropicamide 0.8% and Phenylephrine 5% eye drop kept in lower fornix to dilate the pupil.

Aim: To study the effect of cotton pledget soaked in single drop of Tropicamide 0.8% and Phenylephrine 5% eye drop kept in lower fornix on the pupillary dilatation.

Materials and methods: This is a Prospective Observational study conducted at Sarojini Devi Eye Hospital between October 2014 to September 2016. 400 patients of both sex who required dilatation of pupil for Cataract surgery or posterior segment evaluation are included in the study. Patients who had, Posterior synechiae, sphincter atrophy, Pseudo–exfoliation and any other pupillary abnormality were excluded from the study. Informed consent was obtained from the patients. One drop of Paracaine 0.5% eye drops was instilled in the lower fornix and patient is asked to close the eyelids for five minutes. A cotton pledget soaked in one drop of Tropicamide 0.8% and Phenylephrine 5% combination eye drops was placed in the lower fornix of the patient for 20 minutes. Pupillary dilatation was recorded after 5, 10 and 20 minutes.

Results: 300 patients achieved pupillary dilatation of 6–8mm at the end of 20 minutes. Remaining 100 patients achieved dilatation between 5–6mm at the end of 20 minutes.

Conclusion: By using this method, dilatation of pupil was achieved with single drop of Tropicamide 0.8% and Phenylephrine 5% eye drops sufficient enough to perform cataract surgery and evaluation of fundus oculi.
