Intraoperative electrophysiological evaluations of macular function during peripheral scleral indentation
Scleral indentation is widely used to examine the peripheral fundus, however it can increase the intraocular pressure (IOP) to high levels which can then affect retinal function. We evaluated the effects of scleral indentation on the macular function electrophysiologically. Intraoperative focal macular electroretinograms (iFMERGs) were recorded with and without controlling the IOP in 7 eyes. Wi...
متن کاملPersistence of indentation with bioabsorbable poly-L/D-lactide versus silicone sponge scleral buckling implants.
PURPOSE To measure the amount and duration of indentation depth achieved with biodegradable poly-L/D-lactide 96/4 (PLA96) and silicone sponge implants. METHODS Thirty rabbits underwent a scleral buckling procedure. A PLA96 buckling implant was used in 15 rabbits and a silicone sponge buckling implant was in 15 rabbits. A circumferential scleral buckling implant was sutured episclerally on the...
متن کاملAnterior chamber angle opening during corneoscleral indentation: the mechanism of whole eye globe deformation and the importance of the limbus.
PURPOSE To determine how mechanical interaction among iris, cornea, limbus, sclera, and IOP contribute to angle opening during indentation of the cornea or sclera. METHODS A finite-element model of the globe was developed. The model consisted of three elastic isotropic segments--iris, cornea, and sclera--and a two-component anisotropic segment representing the limbus. The model was tested aga...
متن کاملComplications associated with vortex vein damage in scleral buckling surgery for rhegmatogenous retinal detachment.
PURPOSE To further understand postoperative complications after vortex vein damage during scleral buckling surgery. METHODS The records of 34 patients (34 eyes) with vortex vein damage during scleral buckling surgery for rhegmatogenous retinal detachment were reviewed and compared with the records of 410 eyes undergoing similar surgery without vortex vein damage. RESULTS Postoperative compl...
متن کاملDoes a small central Nd:YAG posterior capsulotomy improve peripheral fundal visualisation for the Vitreoretinal surgeon?
BACKGROUND To evaluate the effect of Nd:YAG capsulotomy for posterior capsular opacification (PCO) on visualisation of the peripheral fundus with scleral indentation. METHODS Patients undergoing Nd:YAG capsulotomy for PCO were examined pre- and four weeks post- Nd:YAG capsulotomy. In order to give a quantitative measure of visualisation of the peripheral retina, a novel scalar measurement was...
