Predicting emulsification in Silicone Oil
Researchers studied straylight in explanted silicone oil samples to predict emulsification, finding increased straylight in samples from patients with visible oil droplets and specific indications, suggesting it as an early indicator for timely silicone oil removal.

Team VitreoSub is a winner!
The provided sources discuss various topics related to the vitreous body and retinal care. The vitreous body is a gel-like substance that fills the posterior chamber of the eye, maintaining the eyeball's shape. Vitreous Retina Macula Consultants of New York (VRMNY) is involved in clinical trials for wet age-related macular degeneration and diabetic macular edema, and their doctors have spoken at conferences on multimodal imaging and ophthalmic ultrasonography. Healio provides news articles, videos, and podcasts on retinal conditions, including the use of multimodal imaging, novel VEGF inhibitors, and mitochondrial stabilizers. Vitreoretinal Consultants of NY shares updates on their practice and announces the win of the Science4Life Venture Cup 2024 by their team, VitreoSub, for developing vitreous body replacement strategies.

Researchers studied how silicone oil adhesion to intraocular lenses (IOLs) affects straylight, finding significant increases in straylight. The study also showed that the cleaning solution F4H5 can reverse straylight values, but surface changes remain.

Overcoming implantation challenges with SING IMT
The SING IMT is a second-generation implantable miniature telescope designed to improve visual acuity and quality of life in patients with late-stage age-related macular degeneration (AMD). It features a smaller incision and improved surgical techniques compared to its predecessor. The device has shown significant improvements in distance and near visual acuity and is considered safe and effective in short-term studies.

Introducing Dynamic Stimulation Aberrometry
Researchers introduced dynamic stimulation aberrometry (DSA) to objectively measure binocular accommodation in 91 patients, finding that accommodative amplitude decreases with age and that DSA records pupil motility dynamically.

Silicone oil drug delivery
"Intravitreal Application: Physicochemical Properties of Drugs Dissolved in Silicone Oils of Different Density in Comparison to the Porcine Vitreous Body" by Hammer et al. (2022) investigates the distribution of anti-infective drugs in silicone oil-filled eyes compared to natural porcine vitreous bodies. The study finds that silicone oil, especially heavier-than-water silicone oil, can be used as a drug reservoir, and that protein binding in the vitreous body occurs with hydrophilic drugs like vancomycin.

Physico-chemical parameters of Silicone Oil
The study examined the effects of biological media on silicone oil used as an intraocular tamponade in retinal detachment surgery. It found that prolonged exposure to the eye does not alter the oil's physicochemical parameters, but the addition of high-molecular-weight components may decrease emulsion stability.

Polyimide cannulas
Researchers compared the injection times of high-viscosity silicone oils using polyimide and metal cannulas. Polyimide cannulas significantly reduced injection times, allowing for the use of ultra-high-viscosity oils, and prewarming the oil further decreased injection times.

Pupil dynamics
This study compares pupil size after three different strategies for intraocular lens (IOL) fixation: anterior iris-fixation, retropupillary iris-fixation, and in-the-bag implantation. The results show that all three strategies do not impair pupil constriction in normal light conditions, but retropupillary iris-fixation results in smaller scotopic pupil sizes compared to the other two methods.
