Purpose:
To establish whether extensive macular atrophy with pseudodrusen (EMAP) can be distinguished from the diffuse-trickling phenotype of geographic atrophy (DTGA) secondary to age-related macular degeneration on the basis of its features on bl…
Purpose:
To investigate the quantitative characteristics of anastomoses of macular neovascularization (MNV) in neovascular age-related macular degeneration using optical coherence tomography angiography according to the frequency of intravitreal in…
Purpose:
To investigate vascular changes of fundus in quiescent Behçet uveitis (BU) based on widefield swept source optical coherence tomography angiography and fluorescein angiography (FA).
Method:
This case–control study included 33 patients with quiescent BU (57 eyes)and 35 healthy people (60 eyes) as the control. All participants underwent the widefield swept source optical coherence tomography angiography, and patients with BU additionally underwent the FA. The quantitative analysis of the widefield swept source optical coherence tomography angiography assessed the vessel density of nine anatomical locations in the fundus. Vascular leakage and retinal nonperfusion on FA were assessed in patients with BU.
Results:
Compared with the control group using Mann–Whitney U test, patients with BU had enlargement of foveal avascular zone (P = 0.005, P = 0.04, respectively) and decreased vessel density within a 300 µm width around the foveal avascular zone (P = 0.001, P
Purpose:
To compare the efficacy of conventional laser and subthreshold micropulse laser (SML) in treating diabetic macular edema in terms of functional outcomes and changes in quantitative metrics for the retinal capillary and choriocapillary vasc…
Purpose:
The objectives were to assess the long-term morphologic and functional outcome of eyes with unclosed macular hole (MH) in which the internal limiting membrane has been peeled in previous vitrectomy with autologous blood clot-assisted lyoph…
Purpose:
The purpose of the study was to report the clinical features and best-corrected visual acuity outcomes in patients with acute- and delayed-onset endophthalmitis after open globe injuries.
Methods:
The study included a retrospective, comparative, consecutive case series of patients with endophthalmitis after open globe injury between January 2016 and October 2020 at the Bascom Palmer Eye Institute.
Results:
Acute-onset endophthalmitis accounted for 16 of 20 cases (80%), and all cases were diagnosed at the initial examination. Delayed-onset endophthalmitis cases, occurring more than 2 weeks after injury, accounted for 4 of 20 cases (20%) and were because of Zone 1 wound leaks and infections. Factors associated with endophthalmitis included presence of a retained intraocular foreign body (11/20 [55%]) and delay of presentation >24 hours (15/20 [75%]) (P
Purpose:
To assess a novel surgical technique to perform macular surgery in high myopic eyes, with axial lengths >34 mm, where standard-size intravitreal surgical instruments cannot reach the retinal surface during pars plana vitrectomy for interna…
Purpose:
To identify the characteristics of the retinal microvasculature in epiretinal membrane patients with ectopic inner foveal layer (EIFL).
Methods:
Patients were classified into two groups: those without EIFL (Group 1) and those with EIFL (Group 2). The vessel density (VD), perfusion density (PD), and the foveal avascular zone (FAZ) parameters were compared using optical coherence tomography angiography. Linear regression analysis was performed to identify the optical coherence tomography angiography parameters associated with best-corrected visual acuity.
Results:
The VD of the central area in Group 1 and Group 2 was 11.6 ± 3.3 and 17.2 ± 2.8 mm−1, respectively (P
