Validity of Aqueous Flare Measurement in Predicting Proliferative Vitreoretinopathy in Patients with Rhegmatogenous Retinal Detachment

Purpose: To investigate aqueous flare as a preoperative predictor for later proliferative vitreoretinopathy (PVR) development in patients with rhegmatogenous retinal detachment (RD) and to determine the validity of this measurement in patients at low clinical risk for postoperative PVR. Methods: This study included 100 eyes of 100 patients who underwent surgery for primary RD. Aqueous flare was determined preoperatively with a laser...

The Effect of the Metabolic Activity of the Retina on the Cholesterol and Fatty Acids’s Contents of the Removed Silicone Oils

Purpose: To investigate the effect of the metabolic activity of the retina on the cholesterol and fatty acid contents of the removed silicone oils. Design: A retrospective trial. Participants: 25 removed silicone oils from 25 eyes were included in the study. Methods: Silicone oils (polydimethylsiloxane) were removed from a total of 25 cases after 4-8 months, who had undergone pars plana vitrectomy combined with phacoemulsification and...

An iPad Application for Fundus Drawings

Purpose: In spite of the availability of good quality wide-angle fundus photography, fundus drawings continue to be highly useful for documenting pertinent features found at the time of fundus examination or as a method of documenting a surgical procedure, highlighting the important facets of an operation. They also serve well as a didactic instrument in the training of retinal specialists. In the age of electronic medical records the...

Thermodynamics in Vitreoretinal Surgery

Advantages: Modulation of variations in temperature occurring inside the human eye during vitreoretinal surgery and of effects of such variations in temperature on intraocular tamponades. Methods: Intraocular temperature was monitored during the entire surgical time in 16 eyes of 16 patients undergoing pars plana vitrectomy. A custom made 25 gauge thermoprobe was inserted through a trocar access at 3.5 mm from the limbus. Temperature in...

A Polymer-based Interface Restores Light Sensitivity in Rat Blind Retinas

Purpose: Sight restoration is one of the new frontiers for prosthetic devices that enable the electrical stimulation o f neurons. In particular, diseases that affect the retinal pigment epithelium and photoreceptors but preserve the inner retinal layers are preferential targets for implantation of visual prostheses. We recently discovered that primary neurons can be successfully grown onto a transparent photovoltaic organic polymer and...

Swelling of the Arcuate Retinal Nerve Fiber Layer (SANFL) After Internal Limiting Membrane Peeling for Idiopathic Macular Hole and Epiretinal Membrane Removal

Antonio Ciardella (Bologna, Italy) Advantages: To report a particular appearance of the fundus, occasionally seen after removal of the internal limiting membrane (ILM). Methods: 56 eyes of 56 consecutive patients with an epiretinal membrane and 38 eyes of 36 consecutive patients with idiopathic macular hole, who underwent pars plana vitrectomy and ILM peeling. All patients received a complete ophthalmic examination, infrared (IR) and...
