In this study, the shrinkage and durability of environmental load-reducing fiber-reinforced polymer cement mortar (FRPCM) were examined by using silicone oil. The results indicated that the shrinkage can be greatly reduced by adding silicone oil. However, when the silicone oil is added in excess, it affects the strength and durability. Therefore, it is possible to obtain the ECO-FRPCM which gives the effect of reducing the shrinkage and maintaining the strength and durability by adding 3% of silicone oil. From the viewpoint of shrinkage reduction, the use of silicone oil is effective as a substitute for an expansive additive or shrinkage reducing agent used in ECO-FRPCM. Also, by appropriately using silicone oil in combination with an expansive additive or a shrinkage reducing agent, shrinkage can be effectively reduced as compared with the conventional ECO-FRPCM. However, when the silicone oil and the shrinkage reducing agent are used in combination, the shrinkage cannot be efficiently reduced. It is considered that the combination of silicone oil and shrinkage reducing agent influences the mutual shrinkage reduction mechanism, but this needs to be further examined in the future.

A characterization study of the anterior segment morphology of patients with and without long-term silicone oil following vitrectomy.
Int Ophthalmol
January 2025
The University of Adelaide, North Terrace, Adelaide, SA, 5000, Australia.
Purpose: To characterize the anterior segment (AS) morphology of patients with long-term silicone oil (SiO) in situ (> 12 months) following pars plana vitrectomy (PPV).
Methods: This prospective, comparative characterization study was conducted between January 2022 and July 2023. Patients were included and sorted based on if they had undergone PPV without long-term SiO or had SiO in situ for at least 12 months at the time of review and image collection.

An analysis of heavy silicone oil treatment for inferior proliferative vitreoretinopathy.
BMC Ophthalmol
January 2025
Oxford Eye Hospital, Oxford University Hospitals NHS Foundation Trust, Oxford, UK.
Purpose: Proliferative vitreoretinopathy (PVR) is a complication of retinal detachment which requires multiple vitreoretinal surgical interventions and frequent use of oil endotamponade. In this study, we conducted an in-depth analysis of complications associated with the use of heavy silicone oil in the management of inferior PVR.
Methods: A retrospective cohort study of 20 eyes that underwent vitrectomy for inferior PVR with use of heavy silicone oil (Densiron 68) between March 2021 and October 2022 at Oxford Eye Hospital.

Purpose: To report a rare case of a Coats-like response developing after vitreoretinal surgery for proliferative diabetic retinopathy (PDR) and its successful management with retinal laser photocoagulation and adjunctive intravitreal steroids.
Case Description: A 52-year-old woman with a five-year history of type 2 diabetes mellitus and hypertension presented with decreased vision in the left eye (counting fingers at 1 m). Examination revealed high-risk PDR in both eyes, with a subtotal macula-off combined retinal detachment in the left eye.
