The analysis of the glaucoma screening event results obtained during the World Glaucoma Week in Zagreb, Croatia.

PURPOSE

To report the prevalence of undiagnosed glaucoma, as well as demographic characteristics and risk factors among glaucoma suspects who were detected in a publicly promoted intraocular pressure (IOP) based glaucoma screening event.

METHODS

A total of 2468 subjects older than 18 years participated in the glaucoma screening event in Zagreb, in 2014, which included a medical interview and IOP measurement using Icare tonometer. 256 subjects (10.37%) were identified as glaucoma suspects, out of which 125 (5.06%) subjects underwent further detailed ophthalmic examination and were classified into five diagnostic groups.

RESULTS

The prevalence of all types of newly diagnosed glaucoma was 1.175%, while the prevalence of ocular hypertension (OH), primary open-angle glaucoma (POAG), primary angle closure (PAC) and secondary glaucoma (SG) was 0.16%, 0.89%, 0.16% and 0.12%, respectively. The prevalence of newly diagnosed glaucoma in glaucoma suspects was 23.2%. 17.60% of glaucoma suspects were diagnosed as POAG. Older age was statistically significantly associated with POAG (p = 0.001) and PAC (p = 0.029). At the univariate level, refractive errors were a statistically significant predictor of POAG, and those with hyperopia had more than three times larger odds for POAG. At the multivariate level, none of the predictors reached statistical significance.

CONCLUSION

Successful cooperation between healthcare institutions and media can be a useful way of increasing awareness and detection of individuals at an increased risk for developing glaucoma.
