INTRODUCTION We present a case of spontaneous suprachoroidal haemorrhage in a patient taking Warfarin. This is only the second case reported of a patient whose anticoagulation was within the therapeutic range. CASE PRESENTATION An 84 year old white male with a history of end stage atrophic age related macular degeneration presented with angle closure glaucoma. The patient was taking warfarin ...
UNLABELLED Retinal visual prostheses ("bionic eyes") have the potential to restore vision to blind or profoundly vision-impaired patients. The medical bionic technology used to design, manufacture and implant such prostheses is still in its relative infancy, with various technologies and surgical approaches being evaluated. We hypothesised that a suprachoroidal implant location (between the scl...
While conventional glaucoma filtration surgery provides excellent intraocular pressure (IOP) lowering effect, this comes at the expense of significant risks. As the physiology of the suprachoroidal space has become better understood, its potential as a source for aqueous drainage has generated significant interest. This has resulted in the creation of several suprachoroidal glaucoma devices wit...
PURPOSE The suprachoroidal location for a retinal prosthesis provides advantages over other locations in terms of a simplified surgical procedure and a potentially more stable electrode-neural interface. The aim of this study was to assess the factors affecting perceptual thresholds, and to optimize stimulus parameters to achieve the lowest thresholds in patients implanted with a suprachoroidal...
Rabbit right eyes were injected with 3 or 6 mg ketorolac tromethamine into the suprachoroidal space. Electroretinography results demonstrated no abnormal changes in rod cell response, maximum rod cell or cone cell mixing reaction, oscillation potential, cone cell response, waveform, amplitude, and potential of 30 Hz scintillation response in right eyes before injection, and at 1, 2, and 4 weeks...
The authors herein report the feasibility of suprachoroidal buckling (SCB) procedure as a new approach for treating different forms of retinal detachment (RD) by creating suprachoroidal indentation (buckling effect). With this technique, specially designed devices, i.e. a catheter or cannula, are guided in the suprachoroidal space to reach the target area. Then, a suprachoroidal filler (long la...
PREOPERATIVE PLANNING Reviewing your patient’s health status and medications preoperatively is mandatory. Someone with poorly controlled blood pressure or heart rate is at greater risk for suprachoroidal hemorrhage (SCH). I like my anesthesia team to know that the control of vital signs is important in glaucoma surgery. Anticoagulant use can contribute to more bleeding should an SCH occur, and ...
