Technologies for multimodal digital imaging of vitreoretinal diseases have improved the accuracy of diagnosis and the depth of the knowledge of the mechanisms of disease and their response to treatments. Optic coherence tomography (OCT) has become a mandatory tool for the management and for the follow-up of retinal pathologies. OCT technology evolved in the last two decades from time-domain to spectral domain and recently to the swept-source OCTs (SS-OCT). SS-OCT improved the depth of imaging and the scan speed, thus adding novel algorithms and features such as for vitreous and vitreoretinal interface evaluation, choroid segmentation and mapping, OCT angiography and En-face OCT...

To report a case of retinal vasoproliferative tumor (VPT) with secondary epiretinal membrane (ERM) formation and vitreo-macular traction managed by pars plana vitrectomy (PPV) and membrane peel. A 29-year-old male was referred for management of decreased vision in the right eye (OD) for 1 week. Presenting visual acuity was 20/50 Snellen feet (ft) OD, and fundus examination showed an ERM associated with a reddish-yellow mass in the inferotemporal quadrant with overlying exudation, hemorrhage, and subretinal fluid consistent with VPT, and cryotherapy was recommended...

Intra-operative optical coherence tomography (OCT) requires a display technology which allows surgeons to visualize OCT data without disrupting surgery. Previous research and commercial intrasurgical OCT systems have integrated heads-up display (HUD) systems into surgical microscopes to provide monoscopic viewing of OCT data through one microscope ocular. To take full advantage of our previously reported real-time volumetric microscope-integrated OCT (4D MIOCT) system, we describe a stereoscopic HUD which projects a stereo pair of OCT volume renderings into both oculars simultaneously...

PURPOSE: Knobloch syndrome is a pathognomonic vitreo-retinopathy that includes zonular weakness, high myopia, and a distinct fundus appearance with tessellation out of proportion to the degree of myopia. Whether myopia in Knobloch syndrome is axial or lenticular is unclear. Also not known are the optical coherence tomography (OCT) correlates to the distinct fundus appearance. In this study we assess cycloplegic refraction, biometry, and macular spectral domain (SD) OCT in children with Knobloch syndrome...

Over the past four decades, advancements in surgical instrumentations and techniques have significantly improved the postoperative anatomical and visual outcomes of patients with various diabetic vitreoretinal diseases. In particular, surgical interventions for previously serious and untreatable blinding proliferative diabetic retinopathy can now be performed, with much better results. The advents of micro incisional vitrectomy system with better visualization system like binocular indirect ophthalmomicroscope and state-of-the-art instrumentation revolutionized the era of diabetic vitrectomy...

Cataract is one of the most common and visually debilitating complications of pediatric uveitis. It develops as a consequence of chronic inflammation and steroid use and is seen most often in juvenile idiopathic arthritis (JIA)-associated uveitis. Cataract extraction with intraocular lens (IOL) insertion has been carried out with a measure of success in non-uveitic pediatric eyes, but in cases of uveitis, multiple factors affect the final outcome. Chronic inflammation and its sequelae such as band keratopathy, posterior synechiae, and cyclitic membranes make surgical intervention more challenging and outcome less certain...

The number of people with diabetic retinopathy (DR) has increased with the increasing prevalence of diabetes mellitus worldwide, especially in developing countries. In recent years, the successful implementation of public health programs in developed countries has been thought to contribute to decreases in blindness from DR. Developing countries, however, have not seen the same improvements, and their public health interventions still face significant challenges. In this review we describe the current state of public health approaches including risk factor control, screening and treatment techniques for DR in developing countries, and suggest recommendations...

PURPOSE: To investigate whether lamellar macular holes can be divided into different subgroups. DESIGN: Retrospective observational case series. METHODS: In this institutional study, clinical charts and spectral-domain optical coherence tomography (OCT) images of 102 eyes of 90 consecutive patients diagnosed with lamellar macular hole were reviewed. In OCT imaging, the presence of lamellar macular hole was defined according to the following findings: presence of irregular foveal contour, separation of the layers of the neurosensory retina, and the absence of full-thickness macular defect...

Small incision cataract surgery (SICS) offers the benefits of a phacoemulsification (phaco) surgery without the attendant high cost, but it is not without certain risk such as nucleus drop into the vitreous as seen in phaco. A retrospective study of SICS and associated factors leading to nucleus drop during surgery, challenges of management and the visual outcomes. Of 793 eye surgeries performed during the study 586 were SICSs. Nucleus drop during SICS occurred in 0.68% of patients. Can-opener technique of capsulotomy, use of dispersive viscoelastic, diabetes mellitus, lack of anterior vitrectomy machine and poor access to immediate posterior vitrectomy were important problems in the management of the cases of nucleus drop in this study...

PURPOSE: To evaluate the structural features of the macular region by enface OCT imaging in patients with clinical diagnosis of Stargardt disease, confirmed by the detection of ABCA4 mutations. METHODS: Thirty-two STGD patients were included in the study for a total of 64 eyes. All patients received a comprehensive ophthalmological examination, color fundus photography, fundus auto-fluorescence imaging and OCT. Five OCT scans were considered: ILM and RPE scans (both automatically obtained from the instrument), above-RPE slab, photoreceptor slab and sub-RPE slab (these last three manually obtained)...

Vitreo-retinal surgery is challenging, as delicate structures have to be manipulated. Eliminating tremor caused by human motions when doing micromanipulation can therefore improve the outcome of such an intervention. An eye surgery robot has been built to overcome this problem. The contribution of this paper is the design of a telemanipulation setup for the robotic system. A telemanipulation setup using a haptic device featuring force feedback as a user interface for controlling a hybrid parallel-serial micromanipulator is designed and developed...

METHODS: Retrospective review of the medical records of 83 patients having undergone a RR between January 2009 and December 2014 to identify patients with BTEP. RESULTS: Six patients aged 31 to 76 were identified...

BACKGROUND: To evaluate a recently established grading protocol for diabetic macular edema (DME) over the course of intravitreal anti-VEGF treatment with ranibizumab. METHODS: Fluorescein angiography images and optical coherence tomography scans before treatment and after 3 monthly applied intravitreal ranibizumab injections were retrospectively graded for each included study eye according to the recently introduced "SAVE" grading protocol ("S"= subretinal fluid; "A"= "area of retinal thickening"; "V"="vitreo-retinal abnormalities"; "E"="etiology of leakage focal versus non-focal") and correlated with best-corrected visual acuity (BCVA) in letters (lett)...

BACKGROUND: Understanding the changes that occur in the choroid is of paramount importance in various uveitis entities. B-scan ultrasonography and indocyanine green angiography can be used to study choroid. Currently, spectral-domain optical coherence tomography is used as the standard noninvasive technique to study the choroid by enhanced depth imaging. Our aim was to study the structural visibility of the choroid using spectral-domain optical coherence tomography in the same area of interest in patients with uveitis with posterior segment manifestations using conventional, enhanced depth imaging (EDI), and combined depth imaging (CDI) techniques...

BACKGROUND: Previous studies described cases of Ocriplasmin injections in patients with vitreo-macular traction and reduced central visual acuity. We describe the first case of a patient with 20/20 visual acuity and vitreo-macular traction treated with Ocriplasmin, and, for the first time in literature, we evaluated the functional changes of the macula in response to pharmacological treatment through multifocal-electroretinogram. CASE PRESENTATION: We report the case of a female Caucasian patient aged 67 years with vitreo-macular traction in the right eye, treated with Ocriplasmin, at the Eye Clinic of the Second University of Naples...
