Filter by:The overall five-year goals of the project are to develop novel technology to provide actionable new information through provision of live volumetric imaging during surgery, improving surgical practice and outcomes. The investigators believe this technology will enable novel ophthalmic and other microsurgeries not possible due to current limitations in surgical visualization.
To describe the technique and outcomes of using either inverted or free internal limiting membrane flap in the management of retinal detachment due to paracentral retinal breaks.
Subjects receiving 16% C3F8 gas tamponade during vitrectomy will have better visual acuity and similar postoperative complications to subjects who receive silicone oil tamponade during vitrectomy.
Patients are required to position prior to retinal detachment surgery. We seek to see whether there is a correlation between the performed positioning and retinal detachment progression/regression in fovea-on retinal detachment patients.
Early Check provides voluntary screening of newborns for a selected panel of conditions. The study has three main objectives: 1) develop and implement an approach to identify affected infants, 2) address the impact on infants and families who screen positive, and 3) evaluate the Early Check program. The Early Check screening will lead to earlier identification of newborns with rare health conditions in addition to providing important data on the implementation of this model program. Early diagnosis may result in health and development benefits for the newborns. Infants who have newborn screening in North Carolina will be eligible to participate, equating to over 120,000 eligible infants a year. Over 95% of participants are expected to screen negative. Newborns who screen positive and their parents are invited to additional research activities and services. Parents can enroll eligible newborns on the Early Check electronic Research Portal. Screening tests are conducted on residual blood from existing newborn screening dried blood spots. Confirmatory testing is provided free-of-charge for infants who screen positive, and carrier testing is provided to mothers of infants with fragile X. Affected newborns have a physical and developmental evaluation. Their parents have genetic counseling and are invited to participate in surveys and interviews. Ongoing evaluation of the program includes additional parent interviews.
All participants will underwent imaging using the OCTA system (Zeiss) with the anterior segment optical adaptor lens. The main outcomes are iris blood flow density and vascular density.
Purpose: To evaluate the logical surgical approaches in closing macular holes in eyes of proliferative diabetic retinopathy with retinal detachment
The purpose of this study is to investigate the loss of retinal cells following retinal detachment surgery using an imaging device called an adaptive optics camera. The retina is a thin layer which lines the back of the eye. It is sensitive to light (like the film in a camera) and is necessary for vision. If a hole or rip develops in a retina it can become detached. The macula is the central portion of the retina which the investigators use for fine vision. This area can also become detached as part of a retinal detachment. Proliferative vitreoretinopathy (PVR) is an abnormal scarring response inside the eye which can occur when the retina detaches. It can adversely affect the outcome of the retinal detachment repair and is associated with a worse visual prognosis. The investigators want to investigate retinal cell loss in patients with retinal detachments that have developed PVR when the macula has been involved. The investigators plan to compare them to two other groups of patients, who have not developed PVR: 1. Patients with macula-involving retinal detachments without PVR 2. Patients with macula-sparing detachments without PVR The investigators will investigate retinal cell loss in these types of retinal detachments using adaptive optics imaging. This is a non-invasive imaging technique which allows the investigators to view the retina at very high magnification. Investigating photoreceptor loss and its association with visual outcome in this way should help to guide future interventions in promoting retinal regeneration. The investigators plan to recruit 25 patients at one UK hospital. The project is funded by the charity Fight for Sight.
To report the surgical results of primary rhegmatogenous retinal detachment (RRD) repaired by 27G pars plana vitrectomy (PPV) combined with Healaflow patch and air tamponade, and do not need prone position postoperation.
Postoperative pain (POP) is frequently underestimated in general and little data are available particularly for POP after vitreoretinal surgery (VRS). The investigators will conduct a 1-year retrospective study on patients undergoing VRS at "Careggi Hospital" . The aim of the study will be to observe the amount of POP, its time course, factors associated with its appearance and finally the efficacy of the pain protocol that is in use.
