Clinical Implications of Suspended Scattering Particles in Motion Observed by Optical Coherence Tomography Angiography.

The objective of this study was to investigate the relationship between suspended scattering particles in motion (SSPiM) in optical coherence tomography angiography (OCTA) and treatment response in diabetic macular edema (DME). We retrospectively reviewed the medical records of patients diagnosed with DME who had undergone intravitreal injection. The optical density ratio (ODR) of the intraretinal cyst and the numbers of hyperreflective foci from OCT images and SSPiM from OCTA images were compared, and their association with treatment response was analyzed.

Effects of a high level of illumination before sleep at night on chorioretinal thickness and ocular biometry.

The choroid is affected by many factors. One of the factors, change in illumination has been suggested to influence choroidal thickness. However, the effects of bright light before sleep at night on the human eye are not well established.

Characteristics of retinal vessels in surgically closed macular hole: an optical coherence tomography angiography study.

Purpose: The purpose of our study was to investigate characteristics of retinal vessels in eyes with surgically closed macular holes (MH).

Methods: We included patients who underwent surgery for idiopathic MH and a follow-up examination using optical coherence tomography angiography (OCTA). The area of the foveal avascular zone (FAZ) and retinal vascular densities of the superficial capillary plexus (SCP) and deep capillary plexus (DCP) were calculated on the postoperative OCTA images and compared with those of age-matched normal controls.

Risk factors of recurrence of macular oedema associated with branch retinal vein occlusion after intravitreal bevacizumab injection.

Background/aims: To identify risk factors of recurrence of macular oedema in branch retinal vein occlusion (BRVO) after intravitreal bevacizumab (IVB) injection.

Methods: The records of 63 patients who underwent IVB injection for macular oedema secondary to BRVO with at least 6 months of follow-up were reviewed. Patients were evaluated at baseline with fluorescein angiography (FA), optical coherence tomography (OCT) and ultra-wide-field fundus photography (WFP).

Ocular Perfusion Pressure and Choroidal Thickness in Early Age-Related Macular Degeneration Patients With Reticular Pseudodrusen.

Purpose: The purpose of this study was to investigate the relationship between the ocular perfusion pressure (OPP) and subfoveal choroidal thickness (CT) in eyes with early age-related macular degeneration (AMD) with or without reticular pseudodrusen (RPD).

Methods: We evaluated the clinical history, blood pressure parameters, fundus photography, and optical coherence tomography images of consecutive patients with early AMD. We calculated the mean OPP from blood pressure and intraocular pressure.

Visual Discomfort While Viewing Three-dimensional Television as a Screening Tool for Pediatric Eye Diseases in Children.

Purpose: To investigate the efficacy of evaluating 3D asthenopia and 3D perception difficulty for screening of binocular vision abnormalities in children.

Methods: Patients aged 6-12 years with abnormal binocularity, including strabismus, amblyopia, and anisometropia, were included. Age-matched normal subjects without any ophthalmologic abnormality other than a refractive error were also recruited.

Relationship between cantho-limbal distance and degree of head turn in a Korean population.

Objective: To evaluate the relationship between cantho-limbal distance and the degree of head turn in Koreans.

Design: Prospective cross-sectional study.

Participants: Thirty patients without strabismus or nystagmus who had visited an ophthalmic clinic at a single medical center were included in the study.

Comparison of intravitreal aflibercept and ranibizumab injections on subfoveal and peripapillary choroidal thickness in eyes with neovascular age-related macular degeneration.

Purpose: We aimed to compare changes in subfoveal and peripapillary choroidal thickness (CT) after intravitreal aflibercept or ranibizumab injections for neovascular age-related macular degeneration (AMD).

Subfoveal and peripapillary CT were measured with images obtained using spectral domain optical coherence tomography at baseline and at three months.

The use of a 20-gauge valved cannula during pars plana phacofragmentation with a 23-gauge ultrasonic fragmatome.

Background And Objective: To evaluate the usefulness of a 20-gauge cannula to maintain a self-sealing sclerotomy wound after 23-gauge phacofragmentation.

Patients And Methods: This retrospective study compared the suture rates after 23-gauge phacofragmentation when the 23-gauge cannula was temporarily replaced with a 20-gauge valved metal cannula versus when the 23-gauge fragmatome was inserted at the sclerotomy site without a cannula.

Results: Whereas a sclerotomy was sutured in all 31 eyes in the without-cannula group, only one eye of 14 in the cannula group required a sclerotomy suture (P < .
