To compare the clinical profile, systemic risk factors, and characteristics of rhegmatogenous retinal detachment (RRD) in pseudophakic and phakic eyes.
Cross-sectional comparative study.
Armed Forces Institute of Ophthalmology, Rawalpindi from August 2013 to August 2015.
A total of 164 eyes (96 pseudophakic patients and 68 phakic patients) with RRD were analyzed. Demographic data and associated known risk factors of study population were acquired. Retinal examination was done by single experienced retinal surgeon using indirect ophthalmoscopy for type of retinal break, location and number of retinal breaks, status of macula, morphological extent of RRD and retinal degenerations. All the findings were endorsed on a pre-devised proforma.
Mean age of patients in pseudophakic and phakic groups was 61.18 ±10.39 and 59.27 ±9.57 years, respectively. Frequency of male patients in pseudophakic and phakic groups was 74% and 57.4%, respectively. Mean axial length in pseudophakic and phakic groups was 23.13 ±2.18 mm and 21.9 ±2.01 mm, respectively. Difference in axial length and gender distribution between two groups was statistically significant (p < 0.05). Difference in frequency of patients with history of hypertension and myopia between two groups was statistically significant (p < 0.05). Characteristics of RRD (type, location and number of retinal breaks, macula status, and extent of RRD) between groups were not statistically significant.
RRD is more common in pseudophakic patients with male gender, increased axial length, myopia, and hypertension.
比较假晶状体眼和有晶状体眼中孔源性视网膜脱离（RRD）的临床特征、全身危险因素及特点。
横断面比较研究。
2013年8月至2015年8月在拉瓦尔品第武装部队眼科研究所。
对164只患有RRD的眼睛（96例假晶状体眼患者和68例有晶状体眼患者）进行分析。获取研究人群的人口统计学数据和相关已知危险因素。由一名经验丰富的视网膜外科医生使用间接检眼镜进行视网膜检查，以确定视网膜裂孔的类型、位置和数量、黄斑状态、RRD的形态范围以及视网膜变性情况。所有检查结果均记录在预先设计的表格上。
假晶状体眼组和有晶状体眼组患者的平均年龄分别为61.18±10.39岁和59.27±9.57岁。假晶状体眼组和有晶状体眼组男性患者的比例分别为74%和57.4%。假晶状体眼组和有晶状体眼组的平均眼轴长度分别为23.13±2.18mm和21.9±2.01mm。两组之间的眼轴长度和性别分布差异具有统计学意义（p<0.05）。两组之间高血压病史和近视患者频率的差异具有统计学意义（p<0.05）。两组之间RRD的特征（视网膜裂孔的类型、位置和数量、黄斑状态以及RRD的范围）无统计学意义。
RRD在男性、眼轴长度增加、近视和高血压的假晶状体眼患者中更为常见。
