    2. Spontaneous resolution of optic pit maculopathy: an OCT report

      Spontaneous resolution of optic pit maculopathy: an OCT report
      The separation of the vitreous from the optic nerve head and the macula plays a primary role in the spontaneous resolution of optic disc pit (ODP) maculopathy. Optical coherence tomography (OCT) helps in the non-invasive monitoring of this condition, when treated conservatively. The aim of this report was to describe a pediatric case of spontaneously resolved ODP maculopathy, managed conservatively and monitored by means of spectral domain (SD)-OCT. A ...

    3. Clear subretinal fluid in a case of non-neovascular early-onset drusen: Swept-source imaging evaluation

      Clear subretinal fluid in a case of non-neovascular early-onset drusen: Swept-source imaging evaluation
      A 50-year-old male presented with recent metamorphopsia in the right eye. Fundus examination revealed bilateral multiple cuticular drusen along with few large colloid drusen (phenotype 3 cuticular drusen). No vitelliform material was evident in the macula in either eye. Fluorescein angiography (FA), indocyanine green angiography (ICGA) did not demonstrate a macular neovascularization (MNV) in either eye. Swept-source optical coherence tomography (SS-OCT) revealed sub-retinal pigment epithelial (RPE) drusen and a clear ...

      Choroidal Rift: A New OCT Finding in Eyes with Central Serous Chorioretinopathy
      Central serous chorioretinopathy (CSC) is a complex and not entirely understood retinal disease. The aim of our research was to describe a novel optical coherence tomography (OCT) finding named choroidal rift, which may be identified in the choroid of eyes with CSC. We collected data from 357 patients (488 eyes) with CSC who had structural OCT and OCT angiography (OCTA) scans obtained. Choroidal rifts were identified as polygonal (and not ...

      Optical coherence tomography angiography findings of fellow eye of proliferative macular telangiectasia type 2: Long term study
      Purpose: To report the characteristics of non-proliferative fellow eyes in patients with unilateral proliferative macular telangiectasia type 2 (MacTel). Methods: This was a multicenter, retrospective study and included fellow eyes of eyes with subretinal neovascular membrane (SRNVM). Multimodal imaging including fundus photography, optical coherence tomography (OCT), and OCT angiography (OCTA) was performed. OCT and OCTA measurements included central macular thickness (CMT), subfoveal choroidal thickness (SFCT), foveal avascular zone (FAZ) area ...

      Advances in imaging of uveitis
      Advances in multimodal imaging have significantly contributed to the management of many uveitis diseases in recent years. The most significant developments include the use of optical coherence tomography to obtain a more accurate and reproducible assessment of ocular inflammation, the application of optical coherence tomography angiography in choroiditis and retinal vasculitis, new possibilities for studying vitritis with ultrawide field imaging, and the most recent applications of fundus autofluorescence in uveitis ...

    9. Quantification of diabetic macular ischemia using novel three‐dimensional optical coherence tomography angiography metrics

      Quantification of diabetic macular ischemia using novel three‐dimensional optical coherence tomography angiography metrics
      We applied three‐dimensional (3D) analysis to optical coherence tomography angiography (OCTA) to measure macular ischemia in eyes affected by non‐proliferative diabetic retinopathy (DR). A previously validated algorithm was applied to OCTA data in order to obtain 3D visualization of the retinal vasculature. Successively, a global thresholding algorithm was applied and two novel quantitative metrics were introduced: 3D vascular volume and 3D perfusion density. Two‐dimensional (2D) OCTA metrics ...

      OCT-A characterisation of recurrent type 3 macular neovascularisation
      Purpose To investigate optical coherence tomography angiography (OCT-A) findings in recurrent type 3 macular neovascularisation (MNV). Methods In this retrospective cohort study, consecutive patients with type 3 MNV secondary to age-related macular degeneration underwent OCT-A at three different time points: baseline, after anti-vascular endothelial growth factor treatment with complete resolution of the exudative signs (ie, non-exudative stage) and at the recurrence of exudation (ie, recurrence stage). Demographics and clinical findings ...

      Macular optical coherence tomography findings after vitreoretinal surgery for rhegmatogenous retinal detachment
      The primary aim of this study was to summarize and illustrate the main structural cross-sectional optical coherence tomography findings encountered after vitreoretinal surgery for rhegmatogenous retinal detachment. This was a non-systematic review of literature on structural cross-sectional optical coherence tomography findings after vitreoretinal surgery for rhegmatogenous retinal detachment. Adequate illustrations of the main findings described were found after a retrospective analysis of imaging and charts of patients operated at the ...

      Optical coherence tomography angiography in diabetes: A review
      Diabetic retinopathy is a common diabetes complication representing a heavy burden in terms of visual impairment and heath expenditure. Optical coherence tomography angiography is a relatively new imaging method and has proven to be a powerful tool in the analysis of diabetic retinopathy common features, including microaneurysms, intraretinal microvascular abnormalities, or neovascularization, as well as in research field, challenging the gold standard of fluorescein angiography. Many studies underlined the vascular ...
