“…The prevalence of PACG is reported to be relatively higher among studies in East Asia [14]. One study in Mongolia reported a 2.8 times higher prevalence of PACG in comparison to POAG [15]. Qualitatively, the similarity observed in disease patterns between these groups and the Maori and Pacific peoples speculate on the existence of genes, which may either protect Maori and Pacific peoples from glaucoma or predispose these ethnicities to certain types of glaucoma.…”

Analysis of Glaucoma Subtypes and Corresponding Demographics in a New Zealand Population

et al. 2016

Purpose: The aim of this paper was to determine the diagnosis distribution and demographic characteristics of glaucoma in a New Zealand population. Methods: The clinical records of all patients presenting consecutively to the Auckland District Health Board Glaucoma Service over a 6-month period were reviewed. Demographic parameters including ethnicity, age at presentation, and gender were collected along with all clinical data. Results: The case records of 857 patients were reviewed. Primary open-angle glaucoma (POAG) was the most common diagnosis (39.0%, n = 235), followed by primary-angle closure (PAC) diagnoses (24.8%, n = 149). This group was formed by the combination of narrow angle 18.1% (n = 109), narrow-angle glaucoma 0.3% (n = 2), PAC 2.1% (n = 13), and PAC glaucoma 4.2% (n = 25). Normal-tension glaucoma (NTG; 17.4%, n = 105), secondary glaucoma (SG; 11.5%, n = 69), ocular hypertension (5.0%, n = 30), and mixed mechanism (2.3%, n = 14) were also found. There was a significant difference in the ethnic distribution in the study population compared to the catchment population (p < 0.001). Caucasian and Indian ethnicities were overrepresented, whereas the Pacific Island Nation ethnicity was underrepresented in all groups except SG. The Maori ethnicity was underrepresented in all groups except PAC. The underrepresentation was most prominent in POAG (only 2 patients of Pacific origin and 1 Maori patient with POAG). Significant differences were identified in gender distribution including a higher preponderance of females in NTG and PAC. Significant differences in age at presentation were also identified between different glaucoma subtypes and ethnicities. Markers of glaucoma severity did not vary with respect to demographic characteristics. Conclusion: In a tertiary glaucoma service in New Zealand, Maori, Pacific peoples, and, to a lesser extent, Asians are underrepresented, while Caucasians and Indians are overrepresented in the glaucoma population.

“…The incidence among Inuits has been reported to be 2–8%, but it is only about 0.1% among Caucasians [1, 2]. In Mongolia [3] or Singapore [4], the reported prevalence is about 1%. The risk of visual impairment and blindness is higher in PACG than in primary open-angle glaucoma [4].…”

“…Acute angle-closure (AAC) attack is characterized by dramatic symptoms and specific clinical findings; it accounts for about 20–35% of PACG [3,4,5]. The incidence has been estimated to be 10.4–12.2/100,000 per year in the population older than 30 years in Hong Kong [6] and Singapore [7], respectively.…”

Ocular Biometry in Acute and Chronic Angle-Closure Glaucoma

Aim: To evaluate the biometric difference between eyes with acute angle-closure (AAC) attack, their uninvolved fellow eyes and eyes with chronic angle-closure glaucoma (CACG). Methods: Patients with prior laser iridotomy on both eyes for unilateral AAC attack or CACG were recruited. We compared ocular biometric parameters by A-scan ultrasonography of the acutely affected eyes with those of the uninvolved fellow eyes and with eyes affected by CACG. Results: Thirty-three patients with unilateral AAC attack and 41 patients with CACG were included. The eyes with AAC attack had a significantly shallower anterior chamber depth (ACD), thicker lens, shorter axial length, higher lens/axial length factor and more anteriorly positioned lens than the eyes with CACG. The uninvolved fellow eyes had a significantly shallower ACD, shorter axial length and higher lens/axial length factor compared with the eyes with CACG. Acutely affected eyes had a shallower ACD and more anteriorly positioned lens than did the uninvolved fellow eyes. Conclusion: Eyes with AAC attack had a more crowded anterior segment compared with uninvolved fellow eyes and those affected by CACG. In addition to ACD, relative lens size, represented by the lens/axial length factor, and relative lens position appear to play important roles in the development of AAC attack.

ABSTRACT. 1) Pseudo-exfoliation syndrome (PE syndrome) is a condition with worldwide distribution. 2) Marked geographical variations have been demonstrated. 3) Environmental factors may be of etiological significance for the development of PE syndrome. 4) The PE syndrome's ability to promote glaucoma may vary from one area to another. 5) There seems to be a trend towards lower debut age of PE syndrome at lower latitudes. 6) More prevalence studies from different parts of the world are needed. A standardized set-up of such works would facilitate comparison of the results, and so some guidelines have been proposed.
