Filter by:To study and compare visual acuity in patients undergoing removal of the epiretinal membrane with and without the removal of the internal limiting membrane at baseline versus 6 month.
Epiretinal membranes (ERM) consist of an abnormal growth of tissue across the retina and are present about 6% of people aged 50 and over. They can cause symptoms of distortion (straight lines appearing bent) or blurred vision. Management options include observation if asymptomatic, or surgery to peel the membrane if symptomatic. Limited data exists regarding how to identify patients who are most likely to benefit from surgery. We propose to measure the effects on distortion (using D chart), visual acuity and vision-related quality of life (using a validated vision-related quality of life questionnaire) of ERM surgery. This will allow us to investigate whether pre-operative D chart score can predict subsequent improvement in quality of life following surgery. We hope the results will help patients and VR surgeons decide whether or not to proceed with ERM surgery. The study will be a prospective case series consisting of patients with symptomatic epiretinal membranes who choose to have epiretinal membrane surgery. The study participants will get standard care with the additional administration of a quality of life questionnaire and measurement of distortion (using a D-chart) at 3 different time points (pre-op, and post-op at 26 and 52 weeks). Recruitment will be in Glasgow, with a possibility of other sites being added on at a later stage.
Blindness can be caused by many ocular diseases, such as diabetic retinopathy, retinal vein occlusion, age-related macular degeneration, pathologic myopia and glaucoma. Without timely diagnosis and adequate medical intervention, the visual impairment can become a great burden on individuals as well as the society. It is estimated that China has 110 million patients under the attack of diabetes, 180 million patients with hypertension, 120 million patients suffering from high myopia and 200 million people over 60 years old, which suggest a huge population at the risk of blindness. Despite of this crisis in public health, our society has no more than 3,000 ophthalmologists majoring in fundus oculi disease currently. As most of them assembling in metropolitan cities, health system in this field is frail in primary hospitals. Owing to this unreasonable distribution of medical resources, providing medical service to hundreds of millions of potential patients threatened with blindness is almost impossible. To solve this problem, this software (MCS) was developed as a computer-aided diagnosis to help junior ophthalmologists to detect 13 major retina diseases from color fundus photographs. This study has been designed to validate the safety and efficiency of this device.
We aimed o compare the refractive changes associated with pars plana vitrectomy with or without intraocular gas tamponade in pseudophakic eyes. This retrospective study included pseudophakic patients with Nd:YAG laser posterior capsulotomy who underwent 23G PPV between February 2015 and March 2019. Group 1 consisted of patients with regmatogenous RD who underwent PPV and 12% perflouropropane (C3F8) gas tamponade whereas Group 2 consisted of patients who underwent PPV for epiretinal membrane or vitreous hemorrhage (VH). No tamponade was used in Group 2. Minimum follow-up was 12 months.
Assessing the efficacy and safety of DEXTENZA, sustained release dexamethasone 0.4 mg inserts following 27 gauge vitrectomy with internal limiting membrane peel
The purpose of this study is to compare the performance and anatomic outcomes of the Sharkskin internal limiting membrane (ILM) forceps and the Grieshaber ILM forceps in macular surgery. Peeling of the ILM is a difficult aspect of vitreoretinal surgery and often daunting task from a vitreoretinal fellow's perspective. The hypothesis is that the newer Sharkskin forceps have a larger platform and micro-abrasions along the forcep surface to increase grasping ability and potentially limit trauma to the retina surface compared to the Grieshaber forceps. This project may also serve as an education tool for fellows learning the basics of ILM peeling.
To report cases who had received previous fovea-sparing internal limiting peeling membrane and developed secondary fovea epiretinal membrane contraction
Report efficiency and clinical outcomes using 25-gauge, bevel-tip, 20000 cut per minute vitrectomy probe among eyes with various vitreo-retinal diseases
The aim of the study is to gain more insight into the potential impact of a vitrectomy (removal of the vitreous) on postoperative effective position of the intraocular lens (IOL). Moreover, this study can provide very useful information for the optimal lens calculation in patients undergoing lens extraction with IOL implantation (whether or not combined with a vitrectomy) should undergo.
The purpose of this study is to compare the efficacy of oral sedation to intravenous sedation with anesthesiology support and monitoring.
