Abstract Visually impaired and blind people due to diabetic retinopathy were 2.6 million in 2015 estimated be 3.2 2020 globally. Though the incidence of is expected decrease for high-income countries, detection treatment it early stages are crucial low-income middle-income countries. Due recent advancement deep learning technologies, researchers showed that automated screening grading efficient saving time workforce. However, most automatic systems utilize conventional fundus photography,...
To describe the pathoanatomy of diabetic macular edema in optical coherence tomography and its correlation with fluorescein angiography patterns.Sixty eyes 56 patients were analyzed. Diabetic was classified into typical focal leakage (from microaneurysm), diffuse (the capillary plexus), or combined/questionable using retinal thickness profiles. The pooling patterns matched to corresponding images analyzed.Focal shows swelling predominantly outer plexiform layer (OPL). Deeply located...
<b><i>Purpose:</i></b> To identify prognostic factors for the visual outcome patients with macula-off rhegmatogenous retinal detachment (RRD). <b><i>Methods:</i></b> The medical records of 27 (27 eyes) RRD were retrospectively investigated. In addition to clinical characteristics, spectral-domain optical coherence tomography (SD OCT) images analyzed. <b><i>Results:</i></b> central foveal thickness at baseline was 923 ±...
To investigate factors associated with long-term recurrence of myopic choroidal neovascularization (CNV) after treatment photodynamic therapy (PDT) and/or intravitreal antivascular endothelial growth factor injections.Seventy-six eyes CNV completed at least a 48-month follow-up treatments. The baseline characteristics the were compared, including age, gender, refractive errors, axial lengths, location CNV, lacquer cracks, chorioretinal atrophy, dark rim, great linear dimension, and prior...
Background/aims To investigate the association between plasma metabolomic profiles and treatment response after intravitreal anti-vascular endothelial growth factor (VEGF) injections in treatment-naïve neovascular age-related macular degeneration (nAMD). Methods This is part of a prospective longitudinal study that included patients with nAMD who have undergone three loading anti-VEGF injections. All underwent ophthalmological examinations including spectral domain optical coherence...
<h3>Background/aims</h3> To investigate the acute effect of ethanol consumption on subfoveal choroidal thickness. <h3>Methods</h3> This prospective interventional study included right eyes 30 healthy subjects (30 eyes). Ethanol (1.0 g/kg) was administered orally first visit. A matching volume water second Oral administration and performed at 14:00, thickness measured every min until 16:00. Change after oral main outcome measure. <h3>Results</h3> At baseline, mean 299.0±73.4 µm (range,...
Purpose To evaluated the changes in choroidal vasculature patients with ocular ischemic syndrome (OIS) and ipsilateral eyes of symptomatic carotid artery stenosis (CAS) Method A total 50 (15 OIS, 10 CAS, 25 age-and sex-matched control group) were included, medical records retrospectively reviewed. The mean subfoveal thickness (SFCT) each eye was measured, binary images choroid to compare area luminal area. Results SFCT 170.5±75.3 μm 154.8±62.9 277.5±73.2 right group (P<0.001)....
A 54-year-old male patient was seen in clinic for ocular pain and decreased vision the right eye with duration of two days.He underwent a cataract operation his 12 years ago, then sclera-fixated secondary intraocular implantation pars plana vitrectomy three ago due to lens dislocation.At initial visit, visual acuity restricted perception hand motion.An edematous cornea, cells, flare hypopyon, exposed suture material at were observed six o'clock direction by slit lamp.Vitreous opacity noted...
A 60-year-old male was referred to the ophthalmologic clinic with aggravated anterior uveitis and corneal edema despite use of topical systemic steroids.He had undergone cataract surgery in both eyes 15 years previous.Slit lamp examinations revealed a retained lens fragment inferior angle chamber, severe mild uveitis.The subsided following surgical extraction fragment.That caused symptomatic after an uneventful is unique.A should be considered as one causes pseudophakic patient.
<b><i>Purpose:</i></b> To compare treatment outcomes of photodynamic therapy (PDT), anti-vascular endothelial growth factor (VEGF) and PDT combined with anti-VEGF for polypoidal choroidal vasculopathy (PCV). <b><i>Procedures:</i></b> A total 62 eyes patients who had completed at least 2 years follow-up were retrospectively reviewed; 19 received only, 23 only 20 underwent combination therapy. Best-corrected visual acuity baseline each visit was...
To evaluate changes in peripapillary choroidal thickness patients with branch retinal vein occlusion (BRVO) over 12 months, using spectral-domain optical coherence tomography enhanced depth imaging.This retrospective, interventional case series included 20 treatment-naive unilateral BRVO at least months follow-up. The was measured months.In BRVO-affected eyes, the mean 213.5 ± 51.7 μm (126.1[FIGURE DASH]326.9 μm) baseline and 129.6 39.3 (65.9[FIGURE DASH]197.1 months. In nonaffected...
Purpose: To evaluate changes in peripapillary choroidal thickness (PCT) and subfoveal (SFCT) after panretinal photocoagulation (PRP) for diabetic retinopathy. Methods: This retrospective interventional study included 59 treatment-naive eyes of 33 patients who underwent PRP completed ≥12 months follow-up. Peripapillary SFCT were measured at baseline 1, 3, 6, 12 post-PRP. Differences between (ΔSFCT ΔPCT) percentage or ΔPCT/baseline × 100%) determined. Results: Mean was 287.7 ± 76.7 μ m...
To investigate clinical characteristics of asymptomatic Terson syndrome and its impact in patients with aneurysmal subarachnoid hemorrhage (SAH).This retrospective, interventional study included 31 SAH, the medical records were reviewed. In addition to baseline population such as age, sex, underlying history, multi-modal imaging analysis, including fluorescein angiography (FA), spectral domain optical coherence tomography (SD-OCT), also Glasgow Coma Scale (GCS), Hunt-Hess (HH) grade, Fisher...
To investigate sectoral changes in the mean peripapillary choroidal thickness (PCT) patients with unilateral branch retinal vein occlusion (BRVO).This retrospective, interventional study included 41 acute, BRVO without macular edema. All completed at least a 6-month follow-up period. The PCT was measured eight locations (temporal, superotemporal, superior, superonasal, nasal, inferonasal, inferior, and inferotemporal). In addition to calculating average of all locations, area divided into...
