To determine the presenting characteristics of rhegmatogenous retinal detachment (RRD) in a consecutive series of Pakistani patients.
Case series.
Layton Rahmatullah Benevolent Trust (LRBT), Lahore, from June 2010 to October 2011.
A total of 107 eyes underwent RRD surgery. Detailed diagrams were drawn pre-operatively for all. Other recorded details included, bio-data, age, gender, visual acuity, autorefractometery, predisposing risk factors, lens state and duration of symptoms. The data was analyzed with respect to age and gender distribution, frequency of various risk factors for RRD, duration of RRD and its various presenting characteristics.
Mean age of the patients were 33.1 ± 1.5 years, 85% were males. Bilateral RRD was discovered in 2.8% patients. No identifiable risk factor for RRD was present in 28%, while in rest of the 72% eyes, the commonest risk factors were intraocular surgery, trauma and peripheral myopic degeneration in decreasing order of frequency. There were 70.1% phakic, 23.4% pseudophakic and 6.5% aphakic eyes. Majority (93.5%) presented with macula off detachment. There was an overall average time lapse of 97.24 ± 16.95 days between presenting and first occurrence of symptoms. In 31.8% of eyes no break could be found pre-operatively, while 38.3% had 1 and 29.9% eyes had ³ 2 breaks. Majority of the primary breaks were horse-shoe tears (42.1%). Total RRD was found in 35.5% eyes. Infero-temporal and supero-temporal were the most frequently involved quadrants (93.5% and 86.9% respectively).
Intraocular surgery, trauma and lattice degeneration in myopia are established common risk factors for RRD. These patients deserve meticulous fundus examination with indentation indirect ophthalmoscopy by trained professionals.
确定一系列连续的巴基斯坦患者中孔源性视网膜脱离（RRD）的表现特征。
病例系列研究。
2010年6月至2011年10月，拉合尔的莱顿·拉赫马图拉慈善信托基金（LRBT）。
共有107只眼睛接受了RRD手术。术前为所有患者绘制详细的图表。记录的其他详细信息包括个人资料、年龄、性别、视力、自动验光、诱发危险因素、晶状体状态和症状持续时间。对年龄和性别分布、RRD各种危险因素的频率、RRD持续时间及其各种表现特征进行了数据分析。
患者的平均年龄为33.1±1.5岁，85%为男性。2.8%的患者发现双侧RRD。28%的患者未发现RRD的可识别危险因素，而在其余72%的眼中，最常见的危险因素依次为眼内手术、外伤和周边近视性变性。有晶状体眼占70.1%，人工晶状体眼占23.4%，无晶状体眼占6.5%。大多数（93.5%）表现为黄斑脱离。从出现症状到首次发作的总体平均时间间隔为97.24±16.95天。31.8%的眼睛术前未发现裂孔，38.3%的眼睛有1个裂孔，29.9%的眼睛有≥2个裂孔。大多数原发性裂孔为马蹄形裂孔（42.1%）。35.5%的眼睛发现全视网膜脱离。颞下象限和颞上象限是最常受累的象限（分别为93.5%和86.9%）。
眼内手术、外伤和近视性格子样变性是公认的RRD常见危险因素。这些患者应接受训练有素的专业人员进行的细致眼底压陷间接检眼镜检查。
