Effects of Alpha-Lytic Therapy Withdrawal on Choroidal Parameters in Intraoperative Floppy Iris Syndrome High-Risk Patients.
J Clin Med

Department of Medicine, Surgery and Dentistry "Scuola Medica Salernitana", University of Salerno, Via S. Allende, 84081 Baronissi, SA, Italy.
: The aim of this study is to investigate the effect on choroidal parameters of drug withdrawal in patients taking α1 adrenergic receptor antagonist (ARA) inhibitors. : In total, 32 eyes of 32 patients under alpha-lytic therapy, and 32 eyes of 32 control subjects, both scheduled for cataract surgery in the fellow eye, were included. EDI-OCT was performed in all patients and subfoveal choroidal thickness (SFCT), luminal choroidal area (LCA), stromal choroidal area (SCA), total choroidal area (TCA), and choroidal vascularity index (CVI) during the preoperative visit were compared with data approximately 1 month after alpha-lytic withdrawal.

Background/objectives: To evaluate the impact of intravitreal bevacizumab (IVB) therapy on anatomical and visual outcomes in patients with macular neovascularization (MNV) secondary to chronic central serous chorioretinopathy (cCSC).
Methods: This retrospective observational study reviewed the medical records of treatment-naïve patients diagnosed with cCSC complicated by MNV and treated with IVB injections over a 5-year period. The presence of MNV was confirmed using optical coherence tomography angiography (OCTA).
Brolucizumab for the Treatment of Diabetic Macular Edema: An Optical Coherence Tomography-Based Analysis.
Diagnostics (Basel)
December 2024
Eye Clinic, Department of Medical, Surgical Sciences and Health, University of Trieste, 34127 Trieste, Italy.
: The objectives of this study were to evaluate the structural and functional outcomes after the loading phase with brolucizumab in switched patients with diabetic macular edema (DME) and to identify potential predictive biomarkers of treatment response. : A total of 28 eyes with DME, switched to brolucizumab, were retrospectively reviewed. Main outcomes during the follow-up period, up to 6 weeks after the fifth injection, included changes in best-corrected visual acuity (BCVA), central subfield thickness (CST), macular volume, subfoveal choroidal thickness, intraretinal and subretinal fluid (IRF and SRF), cyst dimension including maximal horizontal cyst diameter (MHCD), maximal vertical cyst diameter (MVCD), width-to-height ratio (WHR), foveal avascular zone (FAZ) dimension, and vessel density (VD).

Methods: This post-hoc analysis included prospectively collected swept-source optical coherence tomography (SS-OCT) images of a total of 29 cCSCR and fellow eyes (FE), acquired before, one and 12 months after PDT. CVI, total choroidal area (TCA), luminal area (LA) and stromal area (SA) were calculated using validated binarization technique.
Purpose: The aim of the current study was to evaluate changes in choroidal circulation hemodynamics after periocular skin warming at 40°C using laser speckle flowgraphy (LSFG).
Methods: Twenty-four right eyes of 24 healthy participants were included. Changes in choroidal circulation hemodynamics were determined using LSFG to evaluate the mean blur rate (MBR) of the macula, which represents choroidal blood flow velocity.
