AIM

To study the prevalence of pseudoexfoliation in a population based study.

METHOD

2552 patients were selected from camps organized by Sankara Eye Hospital, Shimoga between August 2017 and Dec 2017 in rural areas.On satisfying the inclusion and exclusion criteria, informed consent from the patients will be taken after counselling them regarding the nature of the study.Detailed history regarding any ocular and systemic conditions in accordance with inclusion and exclusion criteria will be noted.Uncorrected visual acuity(UCVA) and best corrected visual acuity (BCVA) for distance using logMAR3 meter chart (English letters or Symbols chart)and near vision using reduced logMAR near vision chart (E– chart or Numbers) will be recorded.Intraocular pressure will be measured using Goldmann’s applanation tonometry. Detailed ophthalmological examination will be done using slit lamp. Gonioscopic examination will be conducted with both indentation and non indentation method.Optic disc examination will be carried out with slit lamp biomicroscopy using +78 D lens, fundus examination using +20D lens. Visual fields and OCT was done if media clear.

RESULT

In this study out of 2552 patients, 135(5.29%) were found to have PXF syndrome.There was a significant increase in prevalence with age but no sex predilection. Out of those 135 cases 18 patients had ocular hypertension (>21 mm Hg), 20patients (14.8%) had open angle glaucoma, and 4 patients (2.9%) had occludable angle glaucoma. Prevalence of OHT, OAG, and closed angles were significantly high amongst people with PXF compared to those without PXF.

CONCLUSION

 In our study, prevalence of pseudoexfoliation was 5.2%.Among pseudoexfoliation, 13.3% had raised intraocular pressure,14.8% had open angle glaucoma and 2.9% had occludable angle glaucoma
