To evaluate the effect of lens status on intraocular pressure (IOP) in siliconized eyes and also on the emulsification of silicone oil.
A total of 31 eyes of 31 patients with retinal detachment were operated on with pars plana vitrectomy and silicone oil injection: 16 phakic (Group A) and 15 pseudophakic (Group B). During the 6-month follow-up period, IOP was measured: 1 day postoperative, then at 1 week, 1 month, 2 months, 3 months, and 6 months postoperative. At the end of the follow-up period, gonioscopy was carried out to check emulsified silicone at the anterior chamber angle and also the presence of emulsified silicone on the back of the cornea when the patient was lying down.
There was no significant difference between both groups until the first week (P value = 0.15). Starting from the first month, the difference was statistically significant, with mean IOPs in Groups A and B of 14.9 mmHg and 18.2 mmHg, respectively, up to the sixth month (P value = 0.002), with a mean IOP in Groups A and B of 14.4 mmHg and 19.4 mmHg, respectively. Emulsified silicone was clinically stated in twelve cases (80%) in Group B and in three cases (19%) in Group A.
There is a higher incidence of increased IOP and emulsification of silicone oil in pseudophakic eyes than in phakic eyes.
评估晶状体状态对硅化眼眼压（IOP）以及硅油乳化的影响。
31例视网膜脱离患者的31只眼接受了玻璃体切除术联合硅油注入手术：16例为有晶状体眼（A组），15例为人工晶状体眼（B组）。在6个月的随访期内，测量眼压：术后1天，然后在术后1周、1个月、2个月、3个月和6个月测量。随访期末，进行前房角镜检查以检查前房角处的硅油乳化情况，以及患者平卧时角膜后表面有无硅油乳化。
两组在术后第一周前无显著差异（P值 = 0.15）。从第一个月开始，差异具有统计学意义，直至第六个月，A组和B组的平均眼压分别为14.9 mmHg和18.2 mmHg（P值 = 0.002），A组和B组的平均眼压分别为14.4 mmHg和19.4 mmHg。临床观察发现，B组有12例（80%）出现硅油乳化，A组有3例（19%）出现硅油乳化。
人工晶状体眼中眼压升高和硅油乳化的发生率高于有晶状体眼。
