Purpose. To report the occurrence of acute, bilateral, central serous chorioretinopathy (CSC), and pachychoroid spectrum disorder findings in patients with coronavirus disease 2019 (COVID-19). Methods. In recovered cases of COVID-19 with visual disturbances, complete ocular examinations with multimodal retinal and choroidal evaluation, including enhanced depth imaging optical coherence tomography, fluorescein or indocyanine green angiography, and blue autofluorescence, were obtained. Results. Four COVID-19 recovered patients presented with bilateral blurred vision. Ocular examination and imaging revealed pachychoroid and pachyvessels associated with choroidal hyperpermeability without any obvious intraocular inflammation. Bilateral localized serous retinal detachment was obvious in three cases compatible with pachychoroid associated with CSC manifestation and pachychoroid pigment epitheliopathy in one patient. CSC was resolved with treatment by steroidal antimineralocorticoid (Eplerenone) in two patients and by photodynamic therapy in one patient. None of the patients reported emotional stress and history of corticosteroid consumption. Conclusion. Hyperpermeability of the choroid, pachychoroidopathy, or choroidal vessel congestion can be observed or exacerbated in association with COVID-19.

Pachychoroid Pigment Epitheliopathy

Purpose: To evaluate choroidal area, stroma/lumen ratio, choriocapillaris vessel density, and choriocapillaris flow area in eyes with central serous chorioretinopathy, uncomplicated pachychoroid, and pachychoroid pigment epitheliopathy using enhanced depth imaging-optical coherence tomography and optical coherence tomography angiography. Materials and Methods: This retrospective study analyzed enhanced depth imaging-optical coherence tomography and optical coherence tomography angiography scans of 142 eyes of 92 patients with central serous chorioretinopathy, uncomplicated pachychoroid, and pachychoroid pigment epitheliopathy. The choroidal area and stroma/lumen ratio were measured by binarization of enhanced depth imaging-optical coherence tomography images. Choriocapillaris vessel density and choriocapillaris flow area were measured at the choriocapillaris level by manual segmentation of optical coherence tomography angiography scans. Results: The mean stroma/lumen ratio results were 0.361, 0.345, and 0.354 in central serous chorioretinopathy, uncomplicated pachychoroid, and pachychoroid pigment epitheliopathy groups, respectively ( p > 0.05). The mean whole image choriocapillaris vessel density in uncomplicated pachychoroid group was higher compared with central serous chorioretinopathy and pachychoroid pigment epitheliopathy groups ( p < 0.0001). The mean foveal, parafoveal, and perifoveal choriocapillaris vessel densities were lower in central serous chorioretinopathy group than in uncomplicated pachychoroid group ( p < 0.0001). The mean choriocapillaris flow area was lower in central serous chorioretinopathy group than in uncomplicated pachychoroid and pachychoroid pigment epitheliopathy groups ( p < 0.0001 and p = 0.01, respectively). Conclusion: Our findings suggest that both choroidal vessels and stroma are equally involved in central serous chorioretinopathy, uncomplicated pachychoroid, and pachychoroid pigment epitheliopathy. The choriocapillaris segment seems to be more affected in central serous chorioretinopathy compared to uncomplicated pachychoroid and pachychoroid pigment epitheliopathy. However, the reduced optical coherence tomography angiography signal in central serous chorioretinopathy group could be due to shadowing artifact or choriocapillaris hypoperfusion and further studies with higher quality imaging tools are needed.

66 healthy people (124 eyes) with different degrees of myopia and emmetropia were examined using enhanced depth imaging optical coherence tomography (EDI-OCT) using the “Spectralis OCT”. It was found that the choroid in subjects with medium and high degrees of myopia was significantly thinner than that in the control group. In the study, a negative correlation was found between the subfoveal choroidal thickness and the degree of myopia (r = -0.75, p < 0.0001). It was also found that the subfoveal choroidal thickness decreased for each diopter of myopia by approximately 18.03 μm.

Active Inflammation

A 38-year-old woman who had previously been diagnosed and treated for unilateral Vogt-Koyanagi-Harada syndrome (VKH) and had undergone multiple intravitreal bevacizumab injections to manage inflammatory choroidal neovascularisation in her right eye, presented 2 years later with visual complains in left eye. Clinical examination, fluorescein angiography, indocyanine green angiography (ICGA) and enhanced depth imaging optical coherence tomography (EDI-OCT) assisted evaluation confirmed active inflammation of left eye along with absence of any inflammation in the right eye. Unilateral active inflammation can be seen in the setting of VKH. To our best knowledge, ours is the first case of VKH in which unilateral active inflammation has been proven based on ICGA and EDI OCT analysis.
