title: Intraocular pressure changes following the use of silicone oil or Densiron 68 as endotamponade in pars plana vitrectomy.
abstract: To compare the effects of standard silicone oil 5700 (SSO) and heavy silicone oil (HSO) such as Densiron(®) 68 on intraocular pressure (IOP).
  
  
  
  Retrospective case series including 180 eyes (105 treated with SSO and 75 with HSO). IOP was measured before surgery, 1 day after, and then at 1-, 3-, 6-, and 12-month follow-ups.
  
  
  
  In the SSO group, a significant increase in IOP occurred in 14% of the eyes (15/105) at 1 day postoperatively, and persisted in 11.4% (12/105) at 1-month follow-up. In the HSO group, a persistent elevated IOP was recorded in 20% of the eyes (15/75) at 1 day postoperatively, and in 16% (12/75) at 1-month follow-up. At 12-month follow-up, mean IOP was 16.7 ± 8.7 mmHg and 19.7 ± 3.8 mmHg, respectively, in the SSO and HSO groups. The difference between the 2 groups was always not significant.
  
  
  
  Overall, the use of Densiron 68 was not associated with higher IOP values as compared with SSO.
