PURPOSE: To investigate the effect of a single intravitreal dexamethasone implant (IVT-DI; Ozurdex; Allergan, Inc.) on visual acuity, macular thickness, and intraocular pressure (IOP) in active noninfectious uveitis. METHODS: Medical records of patients with noninfectious active uveitis treated by IVT-DIs were retrospectively reviewed. Uveitis etiologies, treatment indications, best corrected visual acuity (BCVA), central retinal thickness measured by ocular coherence tomography, IOP, and systemic, local, and topical treatments were collected...

PURPOSE: To study multimodal imaging features of polypoidal choroidal vasculopathy (PCV) associated with central serous chorioretinopathy (CSC) in the same eye. METHODS: A retrospective observational study of cases of suspected PCV which underwent indocyanine green angiography, fundus fluorescein angiography and optical coherence tomography was done, to look for simultaneous typical CSC-like active leak in the same eye. The relevant history, best-corrected visual acuity, optical coherence tomography, fundus fluorescein angiography, and indocyanine green angiography findings were analyzed...

PURPOSE: To determine if the anterior choroid is involved in ocular change during the Valsalva manoeuvre (VM). MATERIALS AND METHODS: Fifty-three healthy volunteers aged 18-65 years with normal visual field test results and no history of intraocular pressure (IOP) exceeding 21 mm Hg were recruited. Anterior and posterior choroidal changes before and during VM were recorded by ultrasound microscope and swept-source optical coherence tomography, respectively. Parameters of the anterior segment included ciliary body thickness (CBT0), thickness of the choroid at a distance of 4 mm from the root of the iris (CT4), anterior placement of the ciliary body (APCB) and trabecular-ciliary angle (TCA)...

PURPOSE: To assess choroidal thickness (CT) and its relationship to retinal sensitivity in mild/moderate age-related macular degeneration (AMD). METHODS: Seventy-two eyes of 51 participants with mild/moderate AMD and 36 eyes of 18 age-matched normal participants were prospectively recruited to undergo enhanced-depth imaging optical coherence tomography (EDI-OCT) imaging and microperimetry (MP) functional assessment. OCT-measured CT and retinal thickness (RT) were matched with MP sensitivity at 13 retinal loci, and correlations were analysed...

Almost 25 years after its introduction, optical coherence tomography (OCT) is still a crucial test in the evaluation of patients affected by diabetic retinopathy. In this chapter, the authors provide an extensive overview of the posterior segment pathological changes induced by diabetes, characterized using OCT. OCT plays a key role in diabetic macular edema (DME) as it assesses related retinal changes both in a qualitative (i.e., DME pattern, presence and aspects of cysts, fluid localization, integrity, and reflectivity of retinal layers) and quantitative (i...

PURPOSE: To assess the effect of intravitreal injection of bevacizumab on central choroidal thickness (CCT) and its relationship with central macular thickness (CMT) and best-corrected visual acuity (BCVA) changes in eyes with center-involving diabetic macular edema. METHODS: This prospective interventional case series included 20 eyes of 20 patients with center-involving diabetic macular edema naive to treatment. The BCVA assessment, complete eye examination, enhanced depth optical coherence tomography, and fluorescein angiography were performed at baseline followed by 3 monthly intravitreal injection of bevacizumab...

PURPOSE: To evaluate the safety and efficacy of selective retina therapy (SRT) with real-time feedback-controlled dosimetry (RFD) in the treatment of chronic central serous chorioretinopathy (CSC). METHODS: In this retrospective case series study, 50 eyes of 49 patients with chronic CSC demonstrating focal or diffuse foveal leakages on fundus fluorescein angiography (FFA) were included. Following evaluation of test spots at temporal arcades, SRT (wavelength 527 nm, pulse repetition rate 100 Hz, pulse energy ramp with maximal 15 pulses) with retinal spot diameter of 200 μm was applied to the areas of each leakage observed on fluorescein angiography...

Choroid has been proposed to participate in the regulation of light refraction by changing its thickness. The present study aims to analyze the characteristics of choroidal thickness (CT), and its correlation with refractive error, axial length and age in young ametropia. A total of 51 subjects (102 eyes), aged from 5 to 18 years old (mean age 10.04 ±2.78 years), with ametropia were included in the study. Choroidal imaging was obtained by enhanced depth imaging (EDI) of spectral domain Optical Coherence Tomography (OCT)...
