Clinical Characteristics of Eyes Showing a Discrete Margin of Different Retinal Reflectivity.

Background And Objective: To evaluate the clinical characteristics of discrete margins of different retinal reflectivity (DMDRR) in ultra-widefield fundus photography.

Patients And Methods: This DMDRR comprises a discrete border, with differing patterns of reflectivity on either side. Spectral-domain optical coherence tomography was performed on both the macula and the margin.

The Structural and Comparative Analysis of Intravitreal Dexamethasone Implant (Ozurdex) and Anti-VEGF Injection in Branched Retinal Vein Occlusion Patients by Optical Coherence Tomography Angiography Images Quantitation.

: To evaluate and compare the structural changes of retinal vasculature after intravitreal dexamethasone implant (Ozurdex) insertion and antivascular endothelial growth factor (anti-VEGF) injection in patients with branched retinal vein occlusion (BRVO) using optical coherence tomography angiography (OCTA).: We retrospectively analyzed 39 patients with unilateral BRVO. Subjects were divided into two groups according to treatment agent: Ozurdex (n = 18) and anti-VEGF (n = 21).

Prevalence of epiretinal membrane in the phakic eyes based on spectral-domain optical coherence tomography.

The prevalence of epiretinal membrane (ERM) and associated factors in the phakic eyes have not been fully elucidated yet. This cross-sectional study included 2,354 phakic eyes without retinal diseases or surgical history. Ocular parameters, such as uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), spherical equivalent (SE), intraocular pressure (IOP), white-to-white corneal diameter (WTW), mean keratometric value (Km) of total corneal refractive power at 4-mm diameter (TCRP4), astigmatism of TCRP4, total corneal irregular astigmatism (TCIA), pupil diameter, axial length (AXL), anterior chamber depth (ACD), lens thickness (LT), and posterior vitreous detachment (PVD) were compared between ERM group and control group.

Risk Factors for Onset or Progression of Posterior Vitreous Detachment at the Vitreomacular Interface after Cataract Surgery.

Purpose: To study the incidence and risk factors for onset or progression of posterior vitreous detachment (PVD) at the vitreomacular interface (VMI) after cataract surgery.

Design: Retrospective case series.

Participants: Patients with a history of phacoemulsification from April 2018 through April 2019 at the Keye Eye Center, Seoul, Korea, and postoperative monitoring for more than 2 months.

Analysis of choroidal thickness and vascularity in patients with unilateral polypoidal choroidal vasculopathy.

Purpose: This study aimed to analyze the choroidal characteristics in eyes with polypoidal choroidal vasculopathy (PCV, affected eyes) and unaffected fellow eyes, and investigated the longitudinal changes in the choroidal structure of fellow eyes in patients with unilateral PCV.

Methods: We retrospectively reviewed the medical records of 55 treatment-naïve patients with unilateral PCV. The choroidal thickness and vascularity between PCV affected eyes, unaffected fellow eyes, and normal control eyes were compared.

Comparative study of tacrolimus and bevacizumab on corneal neovascularization in rabbits.

Purpose: To compare the antiangiogenic effects of tacrolimus and bevacizumab on corneal neovascularization (CNV) in rabbits.

Methods: Neovascularization was induced in 32 eyes of 16 rabbits by placing a suture in the corneal stroma. Seven days after suture placement, all rabbits were divided into 4 groups and were treated subconjunctivally with bevacizumab (AVA_sub) 0.

A case of congenital orbital fibroepithelial polyp.

Fibroepithelial polyp (FEP) is a benign tumor of mesodermal origin, composed of varying amounts of stroma covered by epithelium. The skin and the genitourinary tract are the most common sites of FEP. Uncommon locations of FEP include the inferior turbinate of the nasal cavity, bronchi, and the pharynx.
