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.

Effect of Different Visual Impairment Levels on the Quality of Life in Glaucoma Patients.

The aim of this study was to assess the effect of different visual impairment levels on difference in the subjective quality of life estimation. We included 150 patients with glaucoma whose best-corrected visual acuity in the better-seeing eye was 0.5 and less. All of them were in advanced stage of the disease, with visual field defect worse than 12 dB in mean defect, when measured with the Octopus Visual Field Analyzer. In order to assess the quality of life, we used the Impact of Vision Impairment questionnaire. Additionally, we used General Information Questionnaire, which was developed for the purpose of this study. The information obtained from the questionnaires was analyzed using the Robust Discriminant Analysis program. Difference analysis was performed for each of the three areas of the questionnaire (reading and accessing information, mobility and inde-pendence, and emotional well-being). Results of this study confirmed the difference between the groups of patients with different levels of visual impairment, varying from total visual loss up to vis-ual acuity 0.5 on the better-seeing eye in the effects of visual impairment on the quality of life. All levels of visual impairment had the largest effect in the area of reading and accessing information, slightly less in the area of mobility and independence, and the least effect was in the area of emotional well-being. Based on the results, it is concluded that all levels of visual impairment have negative effect on the quality of life in glaucoma patients.
