To investigate the age at recognition and presentation for surgery for congenital and developmental cataract at Kazakh Eye Research Institute in Kazakhstan.
A retrospective review of children aged 0-18 years, who presented with congenital and developmental cataract between January 1, 2010 and December 31, 2020. All medical records were reviewed. Gender, age at recognition, age at surgery, laterality, residential location (rural/urban) were recorded.
The study population included 897 patients of children presented with congenital and developmental cataract over a 10-year study period, 58% of them were boys and 44.6% were from rural areas. Cataract was bilateral in 621 (69.2%) and unilateral in 276 (30.8%) of patients. Median age at recognition for patients with congenital/developmental cataract was 12 months. Median age at surgery for congenital/developmental cataract was 51 months. Only 14.7% of children underwent surgery within first year of life. The urban citizens underwent surgery earlier than patients from rural areas. The median delay in presentation for surgery was 15 months.
The average age at cataract surgery in the population of Kazakhstan is much older than in developed countries. It is essential to study barriers that associated with delayed presentation to build strategies to overcome them.Key messagesIt is known that cataract surgery in children early in life provides favourable visual outcome.Children with congenital and developmental cataract in Kazakhstan experience delay in surgical treatment.Children from rural areas undergo cataract surgery later than urban citizens.
调查哈萨克斯坦哈萨克眼科研究所先天性和发育性白内障患儿的手术年龄和就诊时间。
回顾性分析 2010 年 1 月 1 日至 2020 年 12 月 31 日期间在哈萨克斯坦哈萨克眼科研究所就诊的 0-18 岁先天性和发育性白内障患儿。所有病历均经审核。记录性别、识别年龄、手术年龄、发病侧别、居住地点（农村/城市）。
本研究共纳入 897 例先天性和发育性白内障患儿，研究期间为 10 年。其中 58%为男孩，44.6%来自农村地区。621 例（69.2%）患儿为双眼白内障，276 例（30.8%）为单眼白内障。先天性/发育性白内障患儿的中位识别年龄为 12 个月，中位手术年龄为 51 个月。仅 14.7%的患儿在 1 岁内接受手术。城镇居民的手术年龄早于农村地区居民。手术延误时间的中位数为 15 个月。
哈萨克斯坦人群白内障手术的平均年龄远大于发达国家。研究与就诊延误相关的障碍对于制定克服这些障碍的策略非常重要。关键信息众所周知，儿童白内障手术越早，视觉预后越好。哈萨克斯坦先天性和发育性白内障患儿的手术治疗存在延误。农村地区的儿童比城市居民接受白内障手术的时间晚。
