Real-world practice patterns of eplerenone use for central serous chorioretinopathy.

Int J Retina Vitreous

Department of Medical Retina and Vitreoretinal Surgery, University of Pittsburgh School of Medicine, 203 Lothrop Street, Suite 800, Pittsburg, PA, 15213, USA.

Purpose: To report eplerenone use by retina specialists worldwide for central serous chorioretinopathy (CSCR).

Methods: A self-reporting questionnaire was distributed to retina specialists worldwide to gather clinicians' perspectives on CSCR cases treated, eplerenone dosage and duration, reasons to use it, and side effects.

Results: The survey included 241 retina specialists (122 Indian and 119 international) with an average experience of 15.

The central serous chorioretinopathy (CSCR) is characterized by serous retinal detachments SRD associated with one or several retinal pigment epithelium detachments/irregularities (PEDs). The choroid is thickened with dilated choroidal veins and choroidal hyperpermeability suggesting an underlying choroidopathy. CSCR belongs to the pachychoroid spectrum.

Purpose: To assess the rate of late phase hyperfluorescent plaque (LPHP) in Type 1 macular neovascularization (MNV) in central serous chorioretinopathy (CSCR) and age-related macular degeneration (AMD) and to evaluate its prognostic value.

Methods: Retrospective study including Type 1 MNV in AMD and CSCR, from 2012 to 2020. Eyes with a late indocyanine green angiography image (>20 minutes) and clear visualization of MNV on optical coherence tomography angiography (OCTA) were included.

Central serous chorioretinopathy (CSCR) is a retinal disease affecting the retinal pigment epithelium (RPE) and the choroid. This is a recognized side-effect of glucocorticoids (GCs), administered through nasal, articular, oral and dermal routes. However, CSCR does not occur after intraocular GCs administration, suggesting that a hypothalamic-pituitary-adrenal axis (HPA) brake could play a role in the mechanistic link between CSCR and GS.

Center-involving diabetic macular edema (DME) is a leading cause of vision impairment in working-age adults. While its management is particularly challenging in a poorly compliant population, continuous innovation and the advent of new molecules have improved its outcome. The control of glycemia and of systemic aggravating factors remain essential to slow down progression of disease complications including DME.

Mineralocorticoid pathway in retinal health and diseases.

In the retina, the mineralocorticoid receptor is expressed in retinal and choroidal vessels and in cells from neural and glial origins. Like in the brain, the major ligand of the mineralocorticoid receptor is cortisol, and the mineralocorticoid/glucocorticoid receptor balance regulates the activation of the MR pathway. Experimental mineralocorticoid receptor pathway activation using either pharmacological agents or transgenic manipulation favours retinal and choroidal pathology.

Mid-Phase Hyperfluorescent Plaques Seen on Indocyanine Green Angiography in Patients with Central Serous Chorioretinopathy.

(1) Indocyanine green angiography (ICG-A) shows the presence of mid-phase hyperfluorescent area in central serous chorioretinopathy (CSCR). However, their exact meaning remains uncertain. (2) The clinical and multimodal imaging findings of 100 patients (133 eyes) with CSCR, including the enhanced-depth-imaging OCT (EDI-OCT), blue-light fundus autofluorescence (BAF), fluorescein and indocyanine green angiography (FA and ICG-A) findings were reviewed.

Pathogenic Effects of Mineralocorticoid Pathway Activation in Retinal Pigment Epithelium.

Glucocorticoids are amongst the most used drugs to treat retinal diseases of various origins. Yet, the transcriptional regulations induced by glucocorticoid receptor (GR) and mineralocorticoid receptor (MR) activation in retinal pigment epithelium cells (RPE) that form the outer blood-retina barrier are unknown. Levels of endogenous corticoids, ligands for MR and GR, were measured in human ocular media.

Diabetic retinopathy remains a major cause of vision loss worldwide. Mineralocorticoid receptor (MR) pathway activation contributes to diabetic nephropathy, but its role in retinopathy is unknown. In this study, we show that MR is overexpressed in the retina of type 2 diabetic Goto-Kakizaki (GK) rats and humans and that cortisol is the MR ligand in human eyes.

The aim of this study was to evaluate the potential anti-angiogenic effect of MTRN (meteorin) in the laser-induced CNV rat model and explore its mechanisms of action. MTRN, thrompospondin-1, glial cell markers (GFAP, vimentin), and phalloidin were immuno-stained in non-human primate flat-mounted retinas and human retina cross sections. The effect of MTRN at different doses and time points was evaluated on laser-induced CNV at 14 days using in vivo fluorescein angiography and ex vivo quantification of CNV.

Mineralocorticoid receptor (MR) contributes to retinal/choroidal homeostasis. Excess MR activation has been shown to be involved in pathogenesis of central serous chorioretinopathy (CSCR). Systemic administration of MR antagonist (MRA) reduces subretinal fluid and choroidal vasodilation, and improves the visual acuity in CSCR patients.

In diabetic retinopathy, the exact mechanisms leading to retinal capillary closure and to retinal barriers breakdown remain imperfectly understood. Rho-associated kinase (ROCK), an effector of the small GTPase Rho, involved in cytoskeleton dynamic regulation and cell polarity is activated by hyperglycemia. In one year-old Goto Kakizaki (GK) type 2 diabetic rats retina, ROCK-1 activation was assessed by its cellular distribution and by phosphorylation of its substrates, MYPT1 and MLC.

Purpose: Targeted drug delivery to the ocular tissues remains a challenge. Biodegradable intraocular implants allow prolonged controlled release of drugs directly into the eye. In this study, we evaluated an anterior suprachoroidal polyurethane implant containing dexamethasone polyurethane dispersions (DX-PUD) as a drug delivery system in the rat model of endotoxin-induced uveitis (EIU).
