• Silicone oil use. It appears that complete filling (see below) reduces the PVR risk [94] by taking away the space in which cells could multiply, especially if heavy silicone oil40 is used [91].

• The true value of heavy silicone oil use is yet to be determined. The rationale is that it does not allow the accumulation of proliferative cells inferiorly, where PVR traditionally starts [82]. The early results of the efficacy of heavy silicone oil use are mixed [72, 82].

• Removal of the ILM during vitrectomy in eyes with high PVR risk may prevent the development of proliferative membranes in the macula, even keep the macula attached in eyes with otherwise total, PVR-re-lated retinal detachment.

• Pharmaceutical approach (Table 2.9.5).
