The Age related Macular Degeneration (AMD) is a common cause of visual impairment and blindness worldwide in elderly.
This study aimed to explore the demographic characteristics, pattern and risk factors for AMD at a tertiary referral eye centre in Nepal.
This is a hospital-based prospective study, conducted at Tilganga Institute of Ophthalmology, Nepal from September 2008 to May 2009. All the consecutive cases of AMD diagnosed at the institute were included.
A total of 141 patients (266 eyes) with AMD recruited for the study. The mean age was 69.5 years (9.1SD) with three fifth males (58.9%). Housewives and occupations like agriculture comprised of 38.3% and 42.5% respectively. Three fourth (75.6%) of the patients were illiterate. The proportion of dry and wet AMD were found in 62.4% and 37.6% respectively. Bilateral involvement was seen in 88.7% of the subjects. Three fourth (71.4%) of the AMD eyes had presenting visual acuity less than 6/18. History of smoking was found in 69.9% of patients. Hypertension was the predominant systemic problem (45.4%) followed by diabetes mellitus (12.8%).
AMD is correlated with ageing in our study as well. Dry AMD is more in age groups 45-64 years and wet AMD at 65 years and older. Bilateral involvement with one eye dry and fellow eye wet AMD is more predominant (44%). Smoking and occupations like agriculture and housewife are significant risk factors for AMD. Likewise male sex, illiteracy and hypertension are other risk factors for AMD in hospital settings.
年龄相关性黄斑变性(AMD)是全球老年人视力损害和失明的常见原因。
本研究旨在探讨尼泊尔一家三级转诊眼科中心AMD的人口统计学特征、模式及危险因素。
这是一项基于医院的前瞻性研究,于2008年9月至2009年5月在尼泊尔蒂尔冈加眼科研究所进行。纳入该研究所诊断的所有连续AMD病例。
共招募了141例(266只眼)AMD患者进行研究。平均年龄为69.5岁(标准差9.1),五分之三为男性(58.9%)。家庭主妇和从事农业等职业的分别占38.3%和42.5%。四分之三(75.6%)的患者为文盲。干性和湿性AMD的比例分别为62.4%和37.6%。88.7%的受试者为双侧受累。四分之三(71.4%)的AMD患眼就诊时视力低于6/18。69.9%的患者有吸烟史。高血压是主要的全身性问题(45.4%),其次是糖尿病(12.8%)。
在我们的研究中,AMD也与衰老相关。45 - 64岁年龄组干性AMD较多,65岁及以上湿性AMD较多。一只眼干性、另一只眼湿性的双侧受累更为常见(44%)。吸烟以及农业和家庭主妇等职业是AMD的重要危险因素。同样,男性、文盲和高血压是医院环境中AMD的其他危险因素。
