Scleral buckling biomaterials and implants for retinal detachment surgery.
Summary of "Scleral buckling biomaterials and implants for retinal detachment surgery."
Scleral buckling is a widely used surgical procedure that aims at repairing retinal detachments. Many materials and procedural techniques have been variously proposed and tested in an attempt to find the best combination for providing optimal results to the patient. This review highlights the evolution of scleral buckling implants and chronicles the main advances that have been made in such a context. Specifically, the limitations of the materials and implants fallen in disuse, as well as the advantages of currently adopted devices are critically examined and discussed. Future directions for the research are considered, underlining in particular the great potential carried by the development of accurate mathematical models for describing the postoperative evolution of buckled eye. These analytical models, supported by a comprehensive data set provided by advanced techniques of medical investigations, may become useful tools for helping surgeons to choose, and to design if necessary, the best buckling material and configuration to be used in each specific clinical case.

Purpose. To observe the long-term effectiveness of scleral buckling and transscleral cryopexy conducted under a surgical microscope in the treatment of uncomplicated rhegmatogenous retinal detachment....
The aim of this study was to investigate the outcomes of one "8"-shaped scleral suture of minimal scleral buckling (MSB) surgery without sub-retinal drainage for rhegmatogenous retinal detachment (RRD...
Abstract Purpose: To describe the clinical characteristics and surgical management of rhegmatogenous retinal detachment (RD) in patients with acute syphilitic panuveitis. Methods: Retrospective case s...
To evaluate the outcomes of vitrectomy without adjuvant scleral buckling for giant retinal tear (GRT) detachment and assess the impact of preoperative lens status on these outcomes.
Rhegmatogenous retinal detachment (RRD) is the separation of the sensory retina from the pigment epithelium (RPE). RRD is caused by a retinal tear in the periphery and the vitreoretinal (VR) traction,...
Assess recovery of macula function after successful scleral buckling surgery for rhegmatogenous retinal detachment by using the multifocal ERG in the postoperative period i.e. recovery of ...
To investigate the feasibility and advantages of using pressurized perfluorocarbon liquid (PCL) perfusion to remove vitreous during suction-cutting 23 GA vitrectomy using a dual, dynamic d...
The purpose of this study is to test if denufosol will remove the fluid build-up in the eye so that the retina can be re-attached without invasive surgery.
The purpose of the study is to compare the safety, intraocular adverse effects and the anatomic and functional outcome with two endotamponade silicone oil after a 3-month in complex inferi...
The purpose of this trial is to access the tolerability of INS37217 Intravitreal Injection when administered intravitreally in subjects with macula-on or macula-off rhegmatogenous retinal ...
Medical and Biotech [MESH] Definitions
An operation for retinal detachment which reduces the size of the globe by indenting the sclera so that it approximates the retina.
Separation of the inner layers of the retina (neural retina) from the pigment epithelium. Retinal detachment occurs more commonly in men than in women, in eyes with degenerative myopia, in aging and in aphakia. It may occur after an uncomplicated cataract extraction, but it is seen more often if vitreous humor has been lost during surgery. (Dorland, 27th ed; Newell, Ophthalmology: Principles and Concepts, 7th ed, p310-12).
Specialized ophthalmic technique used in the surgical repair and or treatment of disorders that include retinal tears or detachment; MACULAR HOLES; hereditary retinal disease; AIDS-related retinal infections; ocular tumors; MACULAR DEGENERATION; DIABETIC RETINOPATHY; and UVEITIS.
Mild to fulminant necrotizing vaso-occlusive retinitis associated with a high incidence of retinal detachment and poor vision outcome.
Multi-channel hearing devices typically used for patients who have tumors on the COCHLEAR NERVE and are unable to benefit from COCHLEAR IMPLANTS after tumor surgery that severs the cochlear nerve. The device electrically stimulates the nerves of cochlea nucleus in the BRAIN STEM rather than the inner ear as in cochlear implants.
