Phacoemulsification and falls are both common in the elderly population. We present a case of acquired total aniridia and vitreous haemorrhage occurring as a result of trauma in a pseudophakic eye.
Interventional case report with history, clinical photograph and discussion with literature review.
A previously healthy 74-year-old Caucasian female was referred with a painful left eye and poor vision following a fall and trauma to the left side of her face. Initial examination confirmed visual acuity of perception of light with total hyphaema and vitreous haemorrhage. Subsequent examination revealed complete aniridia with an intact capsular bag and well-centred posterior chamber intraocular lens and attached retina. Final visual acuity after treatment was 6/9.
Blunt trauma may cause total iris disinsertion in and expulsion from pseudophakic eyes. This relatively novel injury may present increasingly commonly to casualty departments and ophthalmologists.
超声乳化术和跌倒在老年人群中都很常见。我们报告一例在人工晶状体眼外伤后发生获得性全虹膜缺失和玻璃体积血的病例。
采用介入性病例报告，包括病史、临床照片，并结合文献复习进行讨论。
一名既往健康的74岁白种女性因跌倒致左侧面部受伤后出现左眼疼痛、视力下降前来就诊。初步检查证实视力为光感，伴有全前房积血和玻璃体积血。随后的检查发现全虹膜缺失，囊袋完整，后房型人工晶状体位置居中，视网膜附着。治疗后的最终视力为6/9。
钝挫伤可能导致人工晶状体眼中虹膜完全离断并脱出。这种相对罕见的损伤可能会越来越多地出现在急诊科和眼科医生面前。
