Corticosteroids are crucial for treating inflammatory ocular conditions. The development of dexamethasone revolutionized targeted ocular therapy. Ozurdex, a dexamethasone implant, effectively treats various eye conditions but carries risks such as implant migration. This is a case of anterior segment migration of intravitreal dexamethasone implant, Ozurdex, in a patient with scleral fixation intraocular lens implant in whom conservative management with supine positioning and pharmacologic pupil dilation can help retain the implant back in the vitreous...

PURPOSE: To evaluate the short-term effects (hours-days) of intravitreal dexamethasone implant (IDI) in eyes with diabetic macular edema (DME) refractory to anti-vascular endothelial growth factor (VEGF) injections. METHODS: This was a prospective, single-arm, interventional clinical series. Eyes with DME and 3-9 injections of ranibizumab without a good response were included. Patients underwent a single IDI. Best-corrected visual acuity (BCVA) measurement, complete ophthalmic evaluation, and spectral-domain optical coherence tomography (SD-OCT) were performed at baseline, 2 h, 3 h, 24 h, 7 days, and 1 month...

(2) Methods: Prospective interventional analysis on 25 eyes undergoing PPV + Ozurdex (Group A) and 25 eyes undergoing PPV alone. Best corrected visual acuity (BCVA) and OCTA parameters, such as vessel density (VD) of the superficial and deep capillary plexi (SCP and DCP) in the whole 6...

PURPOSE: To report a case of clinically diagnosed cancer-associated retinopathy (CAR) successfully treated with intravitreal corticosteroid implants without systemic immunosuppression. METHODS: Case report with multimodal imaging. RESULTS: An 80-year-old man without known systemic malignancy presented with debilitating shimmering, hemeralopia and rapidly progressive bilateral vision loss following uncomplicated cataract surgery. Mild vitritis, extensive photoreceptor loss, mottling of retinal pigmentary epithelium (RPE), and mild vascular attenuation were found in both eyes...

PURPOSE: Diabetic macular edema (DME) is a significant cause of vision impairment, posing challenges in its management due to variable responses and patient diversity. While anti-vascular endothelial growth factor (anti-VEGF) agents have revolutionized DME treatment, some patients are not suitable candidates for this therapy. Intravitreal corticosteroid therapy, such as the dexamethasone implant (DEX), has emerged as an alternative. This study aimed to comprehensively investigate the role of intravitreal DEX in treatment-naive DME patients with systemic contraindications to anti-VEGF therapy, administered one month before cataract surgery...

Purpose: To assess the impact of switching to, or adding, an intravitreal dexamethasone implant (Dex; Ozurdex® ) in anti-vascular endothelial growth factor (VEGF) therapy on disease stability and treatment intervals in eyes with neovascular age-related macular degeneration (nAMD) and persistent disease activity and high treatment demand. Methods: This retrospective noncomparative multicenter longitudinal case series included pseudophakic eyes with nAMD and persistent retinal fluid despite regular anti-VEGF therapy (ranibizumab or aflibercept) that received at least 1 intravitreal Dex implant...

Diabetic macular edema (DME) is a common sight-threatening complication of diabetic retinopathy (DR) and the leading cause of severe visual impairment among the working-age population. Several therapeutic options are available for the management of DME, including intravitreal corticosteroids. They have been traditionally used as second-line treatment, due to the risk of intraocular pressure increase and cataract-related adverse events. However, attention has recently been focused on the primary or early use of intravitreal corticosteroids, due to growing evidence of the crucial role of inflammation in the pathogenesis of DME...

OBJECTIVES: To assess the risk factors for resistance to first-line therapy and long-term response to dexamethasone intravitreal implant (Ozurdex® ) of patients with macular oedema (MO) secondary to rhegmatogenous retinal detachment repair (RRDR). METHODS: This was a retrospective, consecutive cohort study conducted in patients who underwent RRDR between January 2014 and December 2020 in the Rothschild Foundation Hospital and experienced postoperative MO (POMO) with a follow-up of at least 18 months...

PURPOSE: To describe the common risk factors, complications, and management options for anterior migration of Ozurdex implant. METHODS: A comprehensive review of the literature was performed. RESULTS: Amongst the most common risk factors predisposing to implant anterior migration we found a history of pseudophakia or aphakia or previous vitrectomy. The most common complication is that of corneal edema. CONCLUSIONS: A variety of management options to treat migration of the dexamethasone implant are utilized by different specialists around the world...

Long-acting injectable formulations based on poly(lactide- co -glycolide) (PLGA) have been commercialized for over 30 years in at least 20 FDA-approved products. These formulations offer several advantages, including reduced dosing frequency, improved patient compliance, and maintenance of therapeutic levels of drug. Despite extensive studies, the inherent complexity of the PLGA copolymer still poses significant challenges associated with the development of generic formulations having drug release profiles equivalent to those of the reference listed drugs...

PURPOSE: To report on delayed-onset hyphema following intravitreal injection of dexamethasone implant Ozurdex® in eyes with a history of gonioscopy-assisted transluminal trabeculotomy (GATT). OBSERVATIONS: We describe two cases of hyphema occurring within one day following Ozurdex® implantation in eyes that had undergone GATT at least one year prior. One case responded well to medical management, while the other required anterior chamber paracentesis for intraocular pressure (IOP) control...

Over 20 long-acting injectable formulations based on poly(lactide-co-glycolide) (PLGA) have been approved by the FDA to date. PLGA is a biodegradable polymer that can extend drug release from these dosage forms for up to six months after administration. Despite the commercial success of several of these formulations, there are still a limited number of products that utilize PLGA, and there are currently no generic counterparts of these products on the market. Significant technical challenges are associated with preparation of chemically and structurally equivalent formulations that yield an equivalent drug release profile to the reference listed drug (RLD) both in vitro and in vivo...
