Abstract

PURPOSE: To correlate pupil size and pupillary reaction pre operatively with post- operative vision in lens induced glaucoma. MATERIALS AND METHODS: Settings and Design- Prospective study. Twenty five patients with lens induced glaucoma attending the outpatient and in- patient department, Department of Ophthalmology, K.R.Hospital, Mysore, were included under the study, between the period from January 2014 to July 2014 (6 months). Informed and written consent was taken from all the patients. A detailed history of each patient was obtained regarding the age, sex, ocular symptoms and its duration, past history and treatment history. Routine ocular and systemic examination was done. Pupil size measurement was done using pupillary gauge. Intraocular pressure recording done using rebound tonometry and Biometry was done. All patients then underwent lens extraction with PCIOL implantation. Post op day 1 and day 7 vision was recorded using Snellen's visual acuity chart. STATISTICAL ANALYSIS: All data were analyzed using descriptive statistics and Chi square test and contingency coefficient analysis was applied. RESULTS: Twenty five patients were examined. 17(68%) were Phacolytic type and 8 (32%) were Phacomorphic. It was found that 7 patients ( 28%) had pupil size of 3mm, 8 patients (32%) had 4mm, 6 patients (24%) had 5mm and 4 patients (16%) had 6mm. Post Op day 1 vision were all poor (less than counting fingers 3mts) irrespective of pupil size. Post Op Day 7 vision was better (more than counting fingers 3mts) in patients with pupil size 3mm (P - 0.010), was statistically significant and vision gradually decreased with increase in pupil size. Patients with good pupil reaction at presentation had good post op day 7 vision. CONCLUSION: Lens induced glaucoma patients with smaller pupil size and with better pupillary reaction pre-operatively had good postoperative visual outcome.
