Vkh Disease

Vogt-Koyanagi-Harada (VKH) disease and central serous chorioretinopathy (CSC) develop serous retinal detachment; however, the treatment of each disease is totally different. Steroids treat VKH but worsen CSC; therefore, it is important to distinguish these diseases. Here, we report a case with CSC which was diagnosed by en face optical coherence tomography (OCT) imaging during the course of VKH disease. A 50-year-old man was referred with blurring of vision in his right eye. Fundus examination showed bilateral optic disc swelling and macular fluid in the right eye. OCT showed thick choroid, and en face OCT images depicted blurry choroid without clear delineation of choroidal vessels. Combined with angiography findings, this patient was diagnosed with VKH disease and treated with steroids. Promptly, fundus abnormalities resolved with the reduction of the choroidal thickness and the choroidal vessels became visible on the en face images. During the tapering of the steroid, serous macular detachment in the right eye recurred several times. Steroid treatment was effective at first; however, at the fourth appearance of submacular fluid, the patient did not respond. At that time, the choroidal vessels on the en face OCT images were clear, which significantly differed from the images at the time of recurrence of VKH. Angiography also suggested CSC-like leakage. The tapering of the steroids was effective in resolving the fluid. Secondary CSC may develop in the eye with VKH after steroid treatment. En face OCT observation of the choroid may be helpful to distinguish each condition.

Background: To present an intraoperative acute Descemet’s fold formation using swept-source optical coherence tomography (SS-OCT) imaging. Case Report: A 67-year-old man complaining of reduced visual acuity in the left eye. A 25-gauge pars plana vitrectomy combined with phacoemulsification cataract surgery was performed to remove the vitreomacular traction. When hydro-sealing was performed, striae rapidly spread in the cornea. SS-OCT B-scan images performed on postoperative day 1 revealed a wavy Descemet’s membrane that might correspond to Descemet’s folds. Pairs of hypo- and hyperreflective narrow lesions running from the wavy Descemet’s membrane to almost half of the thickness of the whole cornea were observed. En face OCT imaging clearly showed the stromal fold, which continuously spread from the Descemet’s fold. Conclusion: The stromal fold might be due to the focal bulge of the stroma posteriorly caused by the rapid volume increase of the stroma which could push Descemet’s membrane posteriorly, thereby forming a wavy Descemet’s membrane layer.

Purpose: To describe abnormal dark (hyposignal) and white (hypersignal) lesions observed on optical coherence tomography angiography in central serous chorioretinopathy. Methods: Prospective, multicenter, and descriptive study including patients with active or quiescent central serous chorioretinopathy. All patients had undergone a complete ophthalmic examination. Results: Abnormal dark lesions were detected as “dark spots” and “dark areas” on optical coherence tomography angiography. A “dark spot” could correspond to six different abnormalities: pigment epithelium detachment, subretinal deposit, “Lucency” within surrounding subretinal fibrin, choroidal cavitation, choroidal excavation, and choroidal fluid. A “dark area” could be related to a serous retinal detachment or choriocapillary compression. Abnormal white lesions were also detected: A “white spot” could correspond with the leaking point on fluorescein angiography or with hyper-reflective dots; A “white filamentous pattern” at the Brüch’s membrane level corresponded to abnormal choroidal neovascular vessels. Conclusion: A semiology is described using optical coherence tomography angiography in central serous chorioretinopathy as abnormal dark and white lesions. Multimodal imaging is mandatory in addition to optical coherence tomography angiography to diagnose non-neovascular retinal and choroidal central serous chorioretinopathy lesions. However, optical coherence tomography angiography alone is helpful in detecting choroidal neovascular membrane in central serous chorioretinopathy.

Να μελετηθεί η στιβάδα των φωτοϋποδοχέων, σε οφθαλμούς με κλαδική απόφραξη φλέβας αμφιβληστροειδούς και ισχαιμία ωχράς, χρησιμοποιώντας μία μέθοδο en face optical coherence tomography (OCT) απεικόνισης της ελλειψοειδούς ζώνης.Μέθοδος: Προσαρμοσμένα OCT scans ωχράς, από 9 ασθενείς (10 οφθαλμοί) με κλαδική απόφραξη φλέβας αμφιβληστροειδούς και ισχαιμία ωχράς , εξήχθησαν και επεξεργάστηκαν (αφαίρεση σκιών προερχόμενων από αγγεία και κυστικούς χώρους, διαχωρισμός στιβάδων και ευθειασμός στο επίπεδο του μελάγχρου επιθηλίου). Η ελλειψοειδής ζώνη διαχωρίστηκε, ευθειάστηκε και χρησιμοποιήθηκε για τη δημιουργία της en face OCT εικόνας. Έγινε σύγκριση μεταξύ των υποανακλαστικών περιοχών απώλειας φωτοϋποδοχέων και των ισχαιμικών περιοχών, όπως οι τελευταίες καταγράφηκαν στις πρώιμες φάσεις της φλουοροαγγειογραφίας.Αποτελέσματα: Οι περιοχές απώλειας του τριχοειδικού δικτύου (στη φλουοραγγειογραφία), παρουσίασαν σαφή συσχέτιση με τις περιοχές διαταραχής της ελλειψοειδούς ζώνης (στην en face OCT απεικόνιση). Οι περιοχές διαταραχής της ελλειψοειδούς ζώνης είχαν ανομοιόμορφη εικόνα, και σαφή ή ασαφή όρια, ανάλογα με τη βαρύτητα της βλάβης.Συμπέρασμα: Η en face OCT απεικόνιση της ελλειψοειδούς ζώνης ανέδειξε μία σαφή συσχέτιση μεταξύ της απώλειας του τριχοειδικού δικτύου και των διαταραχών της ελλειψοειδούς ζώνης σε οφθαλμούς με κλαδική απόφραξη φλέβας αμφιβληστροειδούς. Το εν τω βάθει τριχοειδικό δίκτυο προφανώς συμβάλλει σημαντικά στις μεταβολικές ανάγκες του έξω αμφιβληστροειδούς και, κατά συνέπεια, ισχαιμία στο επίπεδο του εν τω βάθει τριχοειδικού δικτύου έχει σοβαρό αντίκτυπο στην ακεραιότητα των φωτοϋποδοχέων.

Torpedo Maculopathy

Purpose: To report a case of torpedo maculopathy presenting with fovea plana in a 21-year-old female patient. Methods: Multimodal imaging including fluorescein angiography, fundus autofluorescence, and spectral domain optical coherence tomography (OCT) was used to characterize pathology. Results: A well-circumscribed ellipsoidal hypopigmented lesion was observed inferotemporal to the fovea OS. Fluorescein angiography and fundus autofluorescence revealed hyperfluorescence and focal hypoautofluorescence, respectively, corresponding to the hypopigmented lesion. Spectral domain optical coherence tomography imaging of the lesion revealed attenuation of the ellipsoid zone and retinal pigment epithelium with a hyporeflective subretinal cleft. En face OCT imaging demonstrated an area of subretinal hyporeflectivity at the subretinal cleft. Spectral domain optical coherence tomography revealed the absence of a foveal pit. Conclusion: We have described a novel case presentation of fovea plana alongside torpedo maculopathy. The significance of this association remains unclear. Further study into these conditions is necessary to help better determine factors responsible for visual symptoms or lack thereof and circumstances that promote their development.

Purpose. The recent use of “en-face” enhanced-depth imaging spectral-domain optical coherence tomography (EDI SD-OCT) helps distinguish the retinal layers involved in the physiopathology of multiple evanescent white dot syndrome (MEWDS).Methods. Four patients presenting with MEWDS underwent a comprehensive ocular examination including C-scan (“en-face”) EDI SD-OCT at the initial visit and during follow-up.Results. C-scans combined with the other multimodal imaging enabled the visualization of retinal damage. Acute lesions appeared as diffuse and focal disruptions occurring in the ellipsoid and interdigitation zones. The match between autofluorescence imaging, indocyanine green angiography, and “en-face” OCT helped identify the acute microstructural damages in the outer retina further than the choroid. Follow-up using “en-face” EDI-OCT revealed progressive and complete recovery of the central outer retinal layers.Conclusion. “En-face” EDI SD-OCT identified the site of initial damage in MEWDS as the photoreceptors and the interdigitation layers rather than the choroid. Moreover, “en-face” OCT is helpful in the follow-up of these lesions by being able to show the recovery of the outer retinal layers.

Purpose To report a case of juxtapapillary polypoidal choroidal neovascularization (PCNV) associated with choroidal nevus investigated by means of optical coherence tomography angiography (OCT-A). Methods Case report. Results A 72-year-old woman presented with visual loss and metamorphopsia in her left eye for 5 days secondary to PCNV that developed on the border of a juxtapapillary choroidal nevus. Fluorescein angiography, indocyanine green angiography, and spectral-domain OCT confirmed the diagnosis. En face OCT-A disclosed a large tangled hyperreflective PCNV spreading from the optic disc at different levels of the choriocapillaris; the polyp lumina appeared hyporeflective. The patient was treated with 3 intravitreal injections of anti-vascular endothelial growth factor with partial functional recovery. Conclusions Our case showed the application of OCT-A in the diagnosis of a case of active PCNV complicating a benign intraocular tumor.

Background and Objective. To correlate optical coherence tomography angiography (OCTA) characteristics of diabetic microaneurysms (MAs) with leakage status on fluorescein angiography (FA). Patients and Methods. 167 MAs from 39 diabetic eyes were analyzed using OCTA and FA simultaneously. The characteristics of MAs on OCTA en face, OCT en face, and OCT B-scan with flow overlay were evaluated and correlated with fluorescein leakage status. Results. Thirty-six, fifty-two, and seventy-nine MAs showed no, mild, and severe leakage on FA, respectively. Most MAs (61.7%) were centered in the inner nuclear layer. Cystoid spaces were observed adjacent to 60 (35.9%) MAs. MAs with severe leakage had a statistically higher flow proportion compared to MAs with no or mild leakage (both P < 0.001 ). Only 112 MAs (67.1%) were visualized in the OCTA en face images, while 165 MAs (98.8%) could be visualized in the OCT en face images. The location of MAs did not associate significantly with FA leakage status. The presence of nearby cystoid spaces and higher flow proportion by OCT B-scan with flow overlay correlated significantly with FA leakage status. Conclusion. The flow proportion of MAs observed on OCT B-scans with flow overlay might be a potential biomarker to identify leaking MAs. A combination of OCT B-scan, OCT en face, and OCTA en face images increased the detection rate of diabetic MAs in a noninvasive way.
