Rationale: Treatment of macular hole retinal detachment (MHRD) in patients with pathologic myopia may require multiple surgeries due to the risk of surgical failures or recurrences. Intravitreal silicone oil injection before an additional surgery may be another option for recurrent MHRD in aphakic eyes, but this procedure is rarely performed.
Patient Concerns: A 69-year-old man visited the hospital with a chief complaint of metamorphopsia in his right eye for 5 days. The right eye had undergone a cataract extraction 5 years prior and an Nd:YAG laser capsulotomy 1 year prior. The axial length was 36.18 mm; the fundus examination and optical coherence tomography (OCT) revealed inferior retinal detachment with a macular hole involving the posterior pole. Pars plana vitrectomy (PPV) with internal limiting membrane (ILM) peeling, endolaser photocoagulation, and silicone oil tamponade were performed. Five months after the surgery, the retina was detached, and a macular hole was observed.
Diagnosis: Recurrent MHRD in a patient with pathologic myopia.
Intervention: PPV with ILM peeling, endolaser photocoagulation, and silicone oil tamponade at the initial visit and additional intravitreal silicone oil injection (0.5 ml) at follow-up visits.
Outcomes: The retina was well-attached until 5 months after the additional intravitreal silicone oil injection.
Lessons: Additional intravitreal silicone oil injection can be a good option for treating MHRD in aphakic eyes if the detachment of the retina is dependent on posturing. The surgeon should consider the volume of silicone oil or postoperative posturing in the treatment of MHRD.

Purpose: The purpose is to evaluate the effect of drainage from intentional extramacular holes after internal limiting membrane insertion to treat macular hole retinal detachment (MHRD) in highly myopic eyes.
Methods: This study is a retrospective, observational, and comparative case series that included 25 consecutive highly myopic eyes with MHRD. All eyes underwent standard 23-gauge vitrectomy, inverted internal limiting membrane insertion into the macular hole, subretinal fluid drainage from an intentionally created extramacular retinal hole, and tamponade with either silicone oil (SO group, n = 13) or perfluoropropane (CF group, n = 12).

Polymer Janus nanoparticles with one hard cross-linked polystyrene lobe and one soft film-forming poly(methyl methacrylate--butyl acrylate) lobe were synthesized by reversible addition-fragmentation chain transfer (RAFT)-mediated emulsion polymerization. The Janus nanoparticles adsorbed to oil/water and air/water interfaces, where the soft lobes coalesced, forming films of thickness between 25 and 250 nm; droplets of silicone oil could be stably encapsulated in polymer in this way. When prepared by mechanical mixing without additives, capsules of diameter 5-500 μm could be prepared, and with additives and application of heat, capsules of diameter around 5 μm were achieved, even with highly viscous silicone oil (20,000 cSt).

Introduction: In facial cosmetic surgery, injectable liquid silicone has been used to augment the cheek and the lips and to camouflage facial wrinkles. However, complications started to arise in 1964 as postoperative silicone granuloma formation. The purpose of this study is to introduce our experience in facial reconstruction after injectable silicon oil with a sequential 3-step approach: transoral surgical excision, full-face fat grafting, and hyaluronic acid filler.

Purpose: To evaluate preoperative and early postoperative factors associated with changes in visual acuity in macula-off rhegmatogenous retinal detachment (RRD) patients.
Methods: A retrospective review of 59 eyes from 59 patients who underwent pars plana vitrectomy (PPV) and silicone oil (SiO) tamponade for macula-off RRD. Preoperative and early postoperative characteristics were analyzed using the classification and regression tree (CART) analysis.

Slippery liquid-infused porous surfaces (SLIPSs) are a class of surface that offers low contact angle hysteresis and low tilt angle for water droplet shedding. This property also endows the surface with pinning-free evaporation, which in turn has been exploited for analyte concentration enrichment for Surface Enhanced Raman Spectroscopic applications and antibiofouling. Herein, we demonstrate a facile approach for creating SLIPS with low contact angle hysteresis and low tilt angle for water shedding by coating the equal-volume mixture of polydimethylsiloxane (PDMS) and silicone oil.
