BACKGROUND Acute retinal necrosis is a rare but devastating ocular condition. We report two cases of acute retinal necrosis in immunocompetent patients, complicated by cystoid macular oedema and treated with intravitreal dexamethasone (OZURDEX®) implant. RESULTS Two patients diagnosed with acute retinal necrosis were treated with intravenous acyclovir. Both of them developed cystoid macular o...
OBJECTIVE To describe surgical strategies in a series of patients with diplopia following implantation of a glaucoma drainage device. METHODS Retrospective review of 9 consecutive patients who underwent strabismus surgery because of strabismus and diplopia after implantation of a glaucoma drainage device. RESULTS Seven patients with marked limitation to ocular rotations and incomitant strab...
Uveitis can be a sight-threatening eye disease with significant morbidity. Corticosteroids remain the mainstay of treatment of uveitis and provide an effective treatment against ocular inflammation. However, the various modes available for corticosteroid drug delivery can carry significant ocular and systemic side effects which can limit their use in the treatment of uveitis. In an effort to av...
Two patients carrying an active subretinal implant with extra-ocular parts were examined by high-resolution CT. Cranial scans were acquired in the primary position and in eight additional directions of gaze with eyes open and closed to demonstrate the mobility of the eyeball and the implant within the orbital cavity. Three-dimensional images were constructed to visualise the path of the implant...
OBJECTIVE To evaluate the efficacy of the 175-mm2 Molteno3 implant in patients with nonneovascular glaucoma. METHODS A hospital-based, retrospective historical control comparative case series comparing results in the first 87 eyes to receive the 175-mm(2) Molteno3 implant with those in a control group of 115 eyes receiving the 274-mm(2) double-plate Molteno implant. RESULTS Success was defi...
PURPOSE To determine the feasibility, safety, and effectiveness of an episcleral or deep scleral lamellar sustained release cyclosporine (CsA) device in a naturally occurring animal model of uveitis. METHODS A two-compartment perfusion chamber was used to assess in vitro human and equine scleral permeability of fluorescein, dexamethasone-fluorescein, or CsA. A biodegradable, matrix-reservoir ...
INTRODUCTION Ocular targeted therapy has enormously been advanced by implementation of new methods of drug delivery and targeting using implantable drug delivery systems (DDSs) or devices (DDDs), stimuli-responsive advanced biomaterials, multimodal nanomedicines, cell therapy modalities and medical bioMEMs. These technologies tackle several ocular diseases such as inflammation-based diseases (e...
PURPOSE To investigate the effectiveness and safety of combined phacoemulsification and dexamethasone intravitreal implant in patients with cataract and diabetic macular edema. METHODS In this two-center, retrospective, single-group study, the charts of 16 consecutive patients who underwent combined phacoemulsification and intravitreal dexamethasone implant were retrospectively reviewed. Thes...
