Purpose: To evaluate possible changes in anterior scleral thickness and structure and changes in the anterior segment in eyes receiving multiple intravitreal injections using ultrasound biomicroscopy imaging.
Methods: Prospective, interventional, nonrandomized, cross-sectional study. Both eyes from 33 patients previously treated at least by 15 intravitreal injections in one eye only for retinal diseases were included.
Background: Optic nerve head drusen (ONHD) are considered the most common cause for pseudopapilloedema in children. We aimed to investigate and further characterize a new type of optic nerve head lesion on enhanced depth imaging optical coherence tomography (EDI-OCT) named peripapillary hyperreflective ovoid mass-like structures (PHOMS), and ONHD in asymptomatic children with pseudopapilloedema.
Methods: Retrospective cohort study including 64 eyes from 32 patients with pseudopapilloedema due to PHOMS and/or ONHD.
Purpose: To investigate the accuracy of high frequency ultrasound biomicroscopy using the bag/balloon technique to locate recti muscle insertions before and after strabismus surgery.
Methods: This was a prospective masked study. The distance from the limbus to horizontal recti muscle insertions was measured by caliper intraoperatively and ultrasound biomicroscopy preoperatively and during follow-up.

August 2019
Background And Objective: Retinal imaging can help differentiate retinoschisis (RS) from retinal detachment (RD). This study describes new sonographic features of RS using ultrasound biomicroscopy (UBM) and evaluates their diagnostic value.
Patients And Methods: Medical records of subjects diagnosed with RS and RD who underwent imaging prior to intervention were reviewed.
Purpose: Aminobisphosphonates may cause orbital/ocular inflammation. Awareness of the clinical presentation and disease course is crucial. The purpose of this study was to analyse demographics, clinical presentation, disease course and treatment of aminobisphosphonate-associated orbital/ocular inflammation in a large series of patients.

We evaluated the potential of adipose-derived mesenchymal stem cells (ASCs) as a therapeutic tool by studying the migration capacity of ASCs and their protective effect against RPE cell death under oxidative stress and . ASCs exhibited enhanced migration when exposed to conditioned medium of oxidative stressed RPE cells obtained by hydrogen peroxide.

Methods: Treatment-naïve AMD eyes with (+) complete PVD and without (-) PVD on ultrasonography received three monthly and then pro re nata bevacizumab injections. Best-corrected visual acuity (BCVA) on Snellen charts and optical coherence tomography (OCT) findings were recorded for 12 months.
Purpose: To investigate spectral domain-optical coherence tomography (SD-OCT) features of untreated circumscribed choroidal hemangioma (CCH), and the optical density (OD) of the associated subretinal fluid (SRF).
Procedures: This international retrospective multicenter study conducted at 5 tertiary retina referral centers included 34 patients with symptomatic CCH imaged on SD-OCT. CCH surface, size, and overlying retinal changes and OD ratio (ODR) were evaluated.
Purpose: To investigate the optical density (OD) characteristics and clinical relevance of subretinal fluid in choroidal melanoma and choroidal metastasis.
Methods: Medical records of patients with choroidal melanoma and choroidal metastasis who underwent optical coherence tomography examinations at diagnosis before any intervention and whose optical coherence tomography scans showed sufficient subretinal fluid for sampling were reviewed. The highest quality B-scan containing subretinal fluid was analyzed.
Background: Thyroid-associated ophthalmopathy (TAO) is an inflammatory disease that affects the thyroid gland and the eye orbit. Of patients with TAO, 3%-5% have severe sight-threatening disease due to optic neuropathy Optical coherence tomography (OCT), the non-invasive imaging technology that yields high-resolution cross-sectional images of the retina, provides qualitative and quantitative data on the retina.
Objectives: To apply this technique to quantitatively assess retinal nerve fiber layer (RNFL) and macular ring thicknesses in healthy subjects and in patients with TAO to determine their relationship to the severity of the orbital disease.
Purpose. To investigate the value of optical coherence tomography (OCT) for differentiation between choroidal melanoma and metastasis based on characteristics of the anterior choroidal surface and the chorioretinal interface. Methods.

Methods: A cross-sectional study. The medical records of 30 patients (33 eyes) with episcleritis or anterior scleritis were reviewed for clinical features and high-resolution UBM findings.

October 2016
Purpose: To investigate macular changes following strabismus surgery by using optical coherence tomography (OCT).
Methods: The authors prospectively evaluated 60 eyes of 30 patients undergoing unilateral extraocular muscle surgery. OCT measurements employing the fast macular thickness mapping protocol were performed 1 day prior to surgery and 1 day postoperatively.
Purpose: To report a unique ocular manifestation of immunoglobulin G4-related disease (IgG4-RD) as choroidal effusion.
Methods: Case report.
Results: An 81-year-old man presented with clinical manifestations of choroidal effusion, confirmed by fluorescein angiography, ophthalmic ultrasound (posterior segment), high-frequency ultrasound biomicroscopy, Heidelberg Spectralis spectral domain optical coherence tomography, and enhanced depth imaging spectral domain optical coherence tomography.
Purpose: To investigate the changes over time in optical density (OD) characteristics of subretinal fluid (SRF) in rhegmatogenous retinal detachment (RRD) and their clinical relevance.
Methods: The study included patients with first-onset RRD and no history of intraocular illness who underwent optical coherence tomography (OCT) and whose OCT scans showed sufficient SRF for sampling (08/2013-09/2014). The highest quality B-scan (as graded by the OCT image acquisition software) containing SRF was analyzed.
Purpose: To assess the efficacy and safety of intraocular injections of bevacizumab in patients with macular edema (ME) following branch retinal vein occlusion (BRVO) and central retinal vein occlusion (CRVO).
Methods: Retrospective, non-comparative case series. Patients ≥18 years of age with ME secondary to BRVO or CRVO who received a minimum of one intravitreal injection of bevacizumab with a follow-up >3 months were included.
Purpose: We sought to assess long-term changes in the flow parameters of retrobulbar vessels in diabetic patients.
Methods: The retrobulbar circulation of 138 eyes was evaluated between 1994 and 1995 and 36 eyes were reevaluated between 2004 and 2008 (study group). They were divided into four groups: eyes of diabetic patients without diabetic retinopathy (DR), eyes with nonproliferative DR, eyes with proliferative DR, and eyes of nondiabetic patients (controls).
Background. Effects of hemodialysis (HD) treatment on retinal thickness and macular edema are unclear. Objective.
View Article and Find Full Text PDFThe purpose of this four year retrospective study was to compare the anatomical and functional outcomes of complicated retinal detachment (RD) surgery by pars plana vitrectomy (PPV) with and without retinotomy. The main outcome measures were primary anatomical success (defined as retinal re-attachment at the final follow-up after a single operation, with or without silicone in situ), final anatomical success, final best-corrected visual acuity (BCVA) and postoperative complications. Baseline characteristics did not differ between the groups, although there was a borderline significant trend for the retinotomy group to be associated with worse pre-surgical ocular pathology.
