Introduction: Significant advances in three-dimensional (3D) imaging technology have allowed for the incorporation of 3D digital displays into medical and surgical devices. Despite initial adoption NGENUITY ® Visualization System vitreoretinal surgery, there are limited publications regarding its use. The generally accepted main benefits include improved ergonomics, enhanced team communication education, reduced retinal phototoxicity, increased depth field, display image manipulation. these...

Visualization during scleral buckling is traditionally achieved via indirect ophthalmoscopy. Recent advances have utilized the surgical microscope and a 25 gauge cannula-based endoillumination system, also known as Chandelier lighting system. This report details an improved approach using guarded or 27 light pipe Ngenuity digital three dimensional platform.A standard Alcon modified with silicone guard to expose only 5 mm of tip pipe. The created from that already opened secure ends...

To report experience with Prosthetic Replacement of the Ocular Surface Ecosystem (PROSE) treatment for complications after laser in situ keratomileuisis (LASIK).Retrospective review clinical and manufacturing records. A database patients who underwent PROSE from 1992 to 2007 was searched yield all history LASIK. Primary indication year LASIK is reported as well contact lens intolerance pretreatment posttreatment best-corrected visual acuity (BCVA).From 2007, 44 (75 eyes) treatment. Patients...

The purpose of this study is to characterize the inflammatory cytokine profile in rhegmatogenous retinal detachments (RRDs) compared surgical controls. Vitreous humor was collected from patients undergoing vitrectomy for RRD and noninflammatory vitreoretinal diseases. A quantitative immunoassay used measure levels 36 markers. Linear regression analysis with duration detachment as predictor log-transformed outcome conducted normally distributed cytokines determined by Shapiro-Wilk test....

Abstract Purpose: To report a rare presentation of Harada’s disease that initially presented as unilateral ring choroidal effusions. Methods: Retrospective chart review. Results: A 42-year-old Trinidadian woman with serous retinal detachment overlying effusions in the absence any systemic symptoms. Visual acuity (VA) was hand motion relative afferent pupillary defect. Biometry revealed an axial length 21.12mm and thickened sclerochoroidal complex. Fluorescein angiography (FA) did not...

Iris pigment epithelial (IPE) cysts are a subset of iris that arise from the IPE. They spontaneously erupting epithelial-lined cavities found in various anatomic locations iris, including pupillary margin, midzone, periphery, and free floating vitreous or anterior chamber. We report case an asymptomatic 13-year-old boy with incidental finding dislodged chamber cyst diagnosed on routine examination. Modern multimodal image analysis segment optical coherence tomography ultrasound biomicroscopy...

To report a novel cause of post-operative reversible visual distortion due to persistent air bubble sequestered at the intraocular lens (IOL)-silicone oil interface.Two cases persistent, IOL-silicone interface were identified and reviewed. Relevant clinical information, images surgical videos analyzed described.Resolution was achieved in both after silicone removal.Silicone adhesion posterior surface IOLs is known degradation. The can sequester that persists causes until removed. We first...
