Current Situation and Challenges in Vitreous Substitutes [PDF]

Macromolecular Bioscience, 2021
AbstractVitreo‐retinal disorders constitute a significant portion of treatable ocular diseases. These pathologies often require vitreo‐retinal surgery and, as a consequence, the use of vitreous substitutes. Nowadays, the vitreous substitutes that are used in clinical practice are mainly divided into gases (air, SF6, C2F6, C3F8) and liquids ...

Treatment of rhegmatogenous retinal detachment: from the past to the future

Journal of Ophthalmology, 2020
Rhegmatogenous retinal detachment (RRD) is a severe disorder that can potentially lead to blindness. The traction developing in pathological attachment of the vitreous to retinal degeneration areas and in posterior hyaloid detachment leads to formation ...

Vitreous substitutes [PDF]

Expert Review of Ophthalmology, 2008
Modern vitreoretinal surgery is a young science. While tremendous developments have occurred in instrument design and technique since Machemer first described vitrectomy surgery in 1973[1], the application of advanced materials concepts to the development of intra-ocular compounds is a particularly exciting area of research. To date, the development of
