The Importance of Signal Strength in Quantitative Assessment of Retinal Vessel Density Using Optical Coherence Tomography Angiography

SCIENTIFIC POSTER The Importance of Signal Strength in Quantitative Assessment of Retinal Vessel Density Using Optical Coherence Tomography Angiography by Jung Yeul Kim, South Korea ABSTRACT The quality of the scan image is important in microvascular circulation analysis using optical coherence tomography (OCTA). We aimed to investigate the effect of signal strength (SS) on OCTA metrics and minimum SS level that could be considered...

Comparison of the Axial Length Measurement by Partial Interferometry and Sonography in the Retinal Vein Occlusion

Poster Jung Yeul Kim Purpose: To investigate the axial length of the retinal vein occlusion using contact A-scan sonography and partial interferometry. Participants: The Nineteen patients diagnosed of acute retinal vein occlusion with macular edema and the 24 patients diagnosed of chronic retinal vein occlusion without macular edema. Methods: The central macular thickness was measured by optical coherence tomography. The axial length was...

Ischemic Changes After Intravitreal Injections for Treatment of ME with CRVO

Advantages: To investigate the ischemic changes after intravitreal injection for treatment of ME with CRVO. Methods:   55 patients treated with anti-VEGF for ME with CRVO were included. Take home message: Intravitreal injection for ME with CRVO could induce ischemic changes in some cases. So these possibilities have to be notified to patients and close follow-up is...

Combined ILM Peeling with Vitrectomy in Macular off Rhegmatogenous Retinal Detachement (RRD)

Jung Yeul Kim, Ki-Yeup Nam, Dong-Won Hu, Haeng-Jin Lee, Young-Joon Jo* (Seoul, South Korea) Advantages: 1. Removal of Remnant Vitreous in posteior pole and easy access of remnant vitreous around hole 2. Prevention of epiretinal membrane and recurrence of recurrent RD Methods: We performed ILM peeling with pars plana vitrectomy in Macular off RRD in 23 patients. ILM peeling was done under heavy liquid and ICG staining. We could confirm...

Combined Cataract Extraction and Pars Plana Vitrectomy for Macular Sparing Rhegmatogenous Retinal Detachment Confirmed by Optical Coherence Tomography

Jung Yeul Kim (Daejeon, South Korea) Purpose: To evaluate visual outcomes of combined cataract extraction and pars plana vitrectomy for macula-sparing rhegmatogenous retinal detachment (RRD) with cataract. Methods: In patients with RRD and cataract in whom the macular are of 6,000 in diameter was not detached on the OCT, a retrospective analysis was performed to examine the results after combined vitrectomy/cataract extraction. Anatomic...

Intravitreal Ranibizumab Combined with Verteporfin Photodynamic Therapy for Treating Polypoidal Choroidal Vasculopathy

Jung Yeul Kim (Daejeon, South Korea) Purpose: To evaluate the efficacy of intravitreal ranibizumab (Lucentis) with verteporfin photodynamic therapy (PDT) for patients with polypoidal choroidal vasculopathy (PCV). Patients and Methods: Seventeen eyes of 17 patients with symptomatic PCV who received three monthly intravitreal ranibizumab injections with PDT were retrospectively reviewed. The follow-up period lasted over 6 months after...

Effect of Topical Brimonidine (0.15%) on the Development of Subconjunctival Hemorrhage following Intravitreal Injection

Author: Jung Yeul Kim, Taejon, South Korea Advantages / Purpose: Brimonidine (0.15%), which is used to lower intraocular pressure, is an α2- adrenergic agonist that has vasoconstrictive effects. This study examined whether the administration of brimonidine (0.15%) before intravitreal injection prevents subconjunctival hemorrhage. Methods: This study examined 188 patients (188 eyes) who underwent intravitreal injection. The control group...
