Stalmans P, Pinxten AM, Wong DS - Retina (Philadelphia, Pa.) (2015)

Bottom Line: Patients treated with F4H5 had borderline significantly less emulsification droplets than those not treated with F4H5.Siluron2000 silicone oil seems to be equally safe and effective as Siluron5000 oil but allows for better handling with the potential of reducing procedure time.The application of F4H5 seems to be safe and effective in reducing residual emulsification.

ABSTRACT

Purpose: To evaluate safety and efficacy of using Siluron2000 silicone oil in the treatment of full-thickness macular hole by comparing its propensity to emulsify with emulsification of the "gold standard" Siluron5000, and to assess safety and efficacy of F4H5 (perfluorobutylpentane) in removing emulsified oil droplets from the eye.

Methods: A single-center, randomized controlled parallel group trial in 72 patients undergoing vitrectomy for treatment of full-thickness macular hole. The study comprises four treatment groups. First, the total patient group was divided into 2 study arms of 36 patients each, receiving either Siluron2000 or Siluron5000 after vitrectomy with a 3-month follow-up after vitrectomy. Second, F4H5 was used during oil removal in half of the patients in each study arm (18 patients within each study arm) with follow-up at 6 weeks after oil removal. Oil droplets were counted within the removed oil; residual emulsification bubbles were quantified using ultrasound imaging.

Results: Safety and efficacy of the oils were comparable. Injection and removal time of Siluron2000 oil was significantly less than that of Siluron5000 oil. Patients treated with F4H5 had borderline significantly less emulsification droplets than those not treated with F4H5.

Conclusion: Siluron2000 silicone oil seems to be equally safe and effective as Siluron5000 oil but allows for better handling with the potential of reducing procedure time. The application of F4H5 seems to be safe and effective in reducing residual emulsification.

Amount of emulsification in anterior chamber (gonioscopy). The amount of emulsification was measured by counting the number of oil bubbles in the anterior chamber using gonioscopy. Compared with the control group, there was a trend toward less oil emulsification bubbles found after application of a F4H5 wash.

Figure 4: Amount of emulsification in anterior chamber (gonioscopy). The amount of emulsification was measured by counting the number of oil bubbles in the anterior chamber using gonioscopy. Compared with the control group, there was a trend toward less oil emulsification bubbles found after application of a F4H5 wash.

Mentions: At 3 months after vitrectomy, gonioscopy was performed in 62 patients. The number of emulsification droplets in patients treated with Siluron2000 did not differ from patients treated with Siluron5000 (P = 0.54). At 6 weeks after oil removal, gonioscopy was performed in 66 patients. The number of emulsification droplets in patients treated with Siluron2000 did not differ from patients treated with Siluron5000 (P = 0.94). When comparing the use of F4H5, patients treated with F4H5 had less emulsification bubbles than those not treated with F4H5, reaching borderline significance (P = 0.061, Figure 4).
