    1. Role of PASCAL and optical coherence tomography angiograpgy in the treatment of diffuse unilateral subacute neuroretinitis caused by large live motile worm

      Role of PASCAL and optical coherence tomography angiograpgy in the treatment of diffuse unilateral subacute neuroretinitis caused by large live motile worm

      A 46-year-old male presented with best corrected visual acuity (BCVA) of 20/125 in his right eye. Fundus showed disc edema, multiple yellow outer retinal crops, macular edema and a live motile worm in the subretinal space. Diagnosis of diffuse unilateral subacute neuroretinitis (DUSN) was made and pattern scanning laser photocoagulation (PSLP) was performed along with administration of oral albendazole, diethylcarbamazine and corticosteroids. Complete disappearance of the worm was observed at 2 weeks. At last follow up, final BCVA improved to 20/30. Herein, we report role of PSLP in the management of DUSN.

    2. Response to anti-vascular endothelial growth factor of abnormal retinal vascular net in para foveal telangiectasia group II images on optical coherence tomography-angiography

      Response to anti-vascular endothelial growth factor of abnormal retinal vascular net in para foveal telangiectasia group II images on optical coherence tomography-angiography

      Purpose: To identify optical coherence tomography-angiography (OCT-A) findings to predict treatment response during anti-vascular endothelial growth factor (VEGF) therapy in eyes with para foveal telangiectasia (PFT) group II. Methods: In this retrospective series, Twelve eyes of seven patients diagnosed with PFT group II without evidence of sub-retinal neovascular membrane (SRNVM) clinically or on spectral domain-OCT (SD-OCT) were included. All patients underwent OCT-A on the Topcon DRI OCT Triton ® with 4.5 mm macula scans. The patients with abnormal vascular nets were further classified into type A and B nets and administered intravitreal anti-VEGF therapy. Visual acuity and size of type ...

    3. Optical Coherence Tomography Angiography

      Optical Coherence Tomography Angiography

      Editorial: Optical coherence tomography angiography (OCT-A) is a relatively new, noninvasive outpatient imaging test that provides both structural and functional information about the macula and midperipheral retina. OCT-A is complementary to traditional imaging modalities, such as fundus photography, fluorescein angiography (FA), and spectral domain optical coherence tomography (SD-OCT). Advantages of OCT-A include visualization of vascular flow signal, en face imaging, no need for dye injection, and segmentation of the posterior segment structures from the vitreomacular interface, through the retinal layers, and to the choroid. Disadvantages of OCT-A include increased costs and longer acquisition times than SD-OCT. Because of the longer ...

    4. Intravitreal Gentamicin-Induced Macular Infarction: SD-OCT Features

      Intravitreal Gentamicin-Induced Macular Infarction: SD-OCT Features
      A 75-year-old woman developed acute-onset endophthalmitis following phacoemulsification in the left eye. She was treated with intravitreal injections of vancomycin, ceftazidime, and gentamicin. The patient had persistent visual loss in the left eye after treatment. Her best-corrected visual acuity was 2/200 in the left eye and examination revealed a pale disc, retinal hemorrhages, and multiple nerve fiber layer infarcts. Fluorescein angiography showed retinal vascular non-perfusion in the macula. On spectral-domain optical coherence tomography (SD-OCT), there was diffuse retinal thinning, absence of the foveal depression, and increased reflectivity of the nerve fiber and ganglion cell layers, but with an intact ...
