Aim: To compare the efficacy of pars plana vitrectomy (PPV) combined with internal limiting membrane (ILM) and silicone oil or sterile air tamponade for the treatment of myopic foveoschisis (MF) in highly myopic eyes.
Methods: This retrospective study included 48 myopic eyes of 40 patients with MF and axial lengths (ALs) ranging from 26-32 mm treated between January 2020 and January 2022. All patients were underwent PPV combined with ILM peeling followed by sterile air or silicone oil tamponade and followed up at least 12mo. Based on the features on spectral-domain optical coherence tomography (SD-OCT), the eyes were divided into the MF-only group (Group A, =15 eyes), MF with central foveal detachment group (Group B, =20 eyes), and MF with lamellar macular hole group (Group C, =13 eyes). According to AL, eyes were further divided into three groups: Group D (26.01-28.00 mm, =12 eyes), Group E (28.01-30.00 mm, =26 eyes), and Group F (30.01-32.00 mm, =10 eyes). The best-corrected visual acuity (BCVA), central foveal thickness (CFT), and complications were recorded.
Results: The patients included 16 males and 24 females with the mean age of 56±9.82y. The BCVA and CFT improved in all groups after surgery (<0.01), while there was no significant difference of the CFT in Group A, B, and C postoperatively (>0.05). The intergroup differences of BCVA and CFT postoperatively were statistically significant in Group D, E, and F. Twenty eyes were injected with sterile air, and 28 eyes were injected with silicone oil for tamponade based on the AL. However, there was no statistically significant difference among Groups D, E, and F in terms of the results of sterile air or silicone oil tamponade. The mean recovery time was 5.9mo for MF patients subjected to silicone oil tamponade and 7.7mo for patients subjected to sterile air tamponade, and the difference was not statistically significant.
Conclusion: PPV and ILM peeling combined with silicone oil or sterile air tamponade can achieve good results for MF in highly myopic eyes with ALs≤32 mm.

Poly(dimethylsiloxane) (PDMS) materials have been widely researched and applied as fouling-release coatings. Incorporation of silicone oils into PDMS has been shown to improve the antifouling properties of PDMS materials. In this research, we applied sum frequency generation (SFG) vibrational spectroscopy to study PDMS materials incorporated with various silicone oils containing phenyl groups in air, water, and protein solutions.

The discharge of oil-laden wastewater from industrial processes and the frequent occurrence of oil spills pose severe threats to the ecological environment and human health. Membrane materials with special wettability have garnered attention for their ability to achieve efficient oil-water separation by leveraging the differences in wettability at the oil-water interface. These materials are characterized by their simplicity, energy efficiency, environmental friendliness, and reusability.

Dielectric capacitors are vital for modern power and electronic systems, and accurate assessment of their dielectric properties is paramount. However, in many prevailing reports, the fringing effect near electrodes and parasitic capacitance in the test circuit were often neglected, leading to overrated dielectric performances. Here, the serious impacts of the fringing effect and parasitic capacitance are investigated both experimentally and theoretically on different dielectrics including AlO, SrTiO, etc.

Rhegmatogenous retinal detachment (RRD) is a severe condition that may lead to permanent vision loss if untreated. Pars plana vitrectomy (PPV) has become a preferred surgical intervention, particularly in complex cases. Objective: Retinal displacement (RD) following PPV for RRD can lead to visual distortions and can negatively impact patient quality of life.

: Rhegmatogenous retinal detachment (RRD) is a potentially blinding retinal disorder. RRD in the first eye is a well-recognized risk factor for bilateral RRD since risk factors that predispose to RRD affect both eyes. In this study, we assess the presenting factors that predispose individuals to bilateral RRD and evaluate the role of prophylactic retinopexy in preventing fellow-eye RRD.
