A 29-year-old female presented to the emergency clinic with gradual visual disturbance in both eyes for 15 days duration, accompanied by bilateral tinnitus, and ocular pain that increased with ocular movements. One month prior to presentation, the patient had tested positive for severe acute respiratory syndrome coronavirus-2 but without complications. Visual acuity was 20/100 in the right eye and 20/300 in the left eye. Funduscopy demonstrated optic nerve swelling, radial nerve fiber striation disruption, and bilateral retinal folds. Optical coherence tomography showed serous (bacillary) retinal detachment and multifocal areas of hyper-reflective changes in the inner and outer plexiform layer with inner nuclear layer thickening and disruption of the interdigitation zone bilaterally. We present a case of incomplete Vogt-Koyanagi-Harada disease following COVID-19 infection.

The majority of cases of orbital emphysema are due to trauma. Complications are rare, and therefore, the need for surgical intervention is uncommon. We present the first case of which we are aware in which nontraumatic orbital emphysema led to orbital compartment syndrome and subsequent optic nerve dysfunction. The patient underwent emergency needle decompression. A 51-year-old man presented to the Emergency Department with right-sided unilateral proptosis, reduced visual acuity, and binocular diplopia. This occurred after performing a Valsalva manoeuvre with no history of head trauma. He also mentioned that over the past year he had experienced multiple episodes of transient proptosis occurring after Valsalva manoeuvres. Visual acuity in the right eye was reduced to 6/21. A relative afferent pupillary defect was present and intraocular pressure (IOP) was 12 mmHg. The CT scan showed significant orbital emphysema in the medial aspect of the right orbit. Needle decompression was performed resulting in immediate resolution of his symptoms. This case demonstrates that, in cases of orbital emphysema, a lack of a history of trauma and a normal IOP cannot always be used to rule out serious pathology.

Background: We report a case of different types of maculopathy in eyes after a high-voltage electrical shock injury. Case Report: A 43-year-old male suffered high-voltage electrical injury through his left arm. He underwent cataract surgery in both eyes 3 months after the injury, but there was no vision improvement. Ocular examination, including spectral domain optical coherence tomography, revealed diffuse retinal atrophy in the left eye which did not change until the final visit. In the right eye, an impending macular hole was observed but regressed spontaneously 9 months after the injury, and the visual acuity improved to 20/32 at the final visit. Conclusion: Two different types of maculopathy can occur in each eye after high-voltage electrical shock injury, and this might be due to asymmetric pathogenesis of the eyes according to the proximity to the route of electrical current.

The purpose of this report is to describe a case of bilateral foveal hypoplasia in the absence of other ophthalmological or systemic manifestations. We characterize the case of a 9-year-old Caucasian male who underwent full ophthalmologic examination, including functional measures of vision and structural measurements of the eye. Best corrected visual acuity was 0.50 logMAR in the right eye and 0.40 logMAR in the left eye. Ophthalmoscopy revealed a lack of foveal reflex that was further investigated. Optical coherence tomography (OCT) confirmed the absence of foveal depression (pit). OCT images demonstrated the abnormal structure of retina in a region in which we expected a fovea; these findings were decisive to determine the cause of reduced acuity in the child.

Purpose: To report the morphological and clinical features of a case of pachychoroid disease with focal choroidal excavation and large choroidal excavation complicated by choroidal neovascularization. Methods: The patient underwent a complete ophthalmologic examination including best-corrected visual acuity assessment, anterior segment and dilated fundus examination, fluorescein and indocyanine green angiography, and spectral-domain optical coherence tomography. Results: During the previous follow-up, the 57-year-old man received a diagnosis of central serous chorioretinopathy in the right eye with a late appearance of a choroidal neovascularization. The best-corrected visual acuity was 20/125 and 20/20 in the right and left eye, respectively. Dilated fundus examination, fluorescein angiography, and indocyanine green angiography confirmed a large subretinal fibrosis corresponding to the evolution of the choroidal neovascularization in the right eye. Spectral-domain optical coherence tomography clearly demonstrated in the right eye a large choroidal excavation below the fibrotic neovascular lesion with multiple hyperreflective foci inside the cavity, and in the left eye, a conforming focal choroidal excavation, bowl-shape type, associated with increased choroidal thickness with pachyvessels. Conclusion: Large choroidal excavation has been rarely reported. Although the pathogenetic mechanisms leading to the formation of large choroidal excavation are still only hypotheses, a combination of primary degenerative inflammatory factors sustaining the focal choroidal excavation formation and disruptive process of the choroidal neovascularization could be retained responsible for the large choroidal excavation.

Purpose: To report a case of type 3 neovascular lesion in a patient with retinitis pigmentosa (RP) complicated by macular edema. Case Report: A 78-year-old man with a long follow-up for RP was referred for painless visual acuity decrease in the right eye. Best-corrected visual acuity was 20/125 in the right eye and 20/40 in the left. Fundus examination showed typical RP and macular edema in both eyes. In the right eye, spectral domain optical coherence tomography revealed a marked cystic macular edema associated with disruption of the Bruch membrane/retinal pigment epithelium complex overlying a pigmentary epithelium detachment, with a vascular structure which appeared to originate from the deep capillary plexus and to be connected with the subretinal pigment epithelium space. Optical coherence tomography angiography showed a high-flow vessel infiltrating the outer retinal layers in the deep capillary plexus segmentation, and a tuft-shaped, bright, high-flow network that seemed to be connected with the subretinal pigment epithelium space in the outer retinal layer segmentation. This presentation was consistent with an early type 3 neovascular lesion in the right eye. Conclusion: Type 3 neovascularization may be considered a possible complication of RP.

ABSTRACT Introduction: to report a case of bilateral leukemic retinopathy due to leukostasis that was successfully managed by leukapheresis. Case Presentation: 31-year-old male with mild visual disturbance was referred to ophthalmology department. He suffered from Chronic Myelogenous Leukemia (CML) with white blood cell (WBC) count 533.900/microL. He was started on hydroxyurea, allopurinol, and once leukapheresis. Ophthalmologic evaluation revealed visual acuity of 4/4 in the right eye and 4/6,3 in the left eye. Funduscopy examination showed the presence of bilateral papilledema, venous engorgement, tortuosity, and retinal hemorrhages. Then this patient continued with second leukapheresis. Result: Visual acuity, laboratory examination, and funduscopic finding was evaluated. His visual acuity was improved, papilledema and retinal blood vessels abnormality had markedly reduced concurring with the patient’s hematological remission. Decreasing WBC count after leukapheresis has improved blood flow that reflected from the retinal findings and visual acuity improvement. Conclusion: Leukapheresis treatment is sufficient to improved clinical condition for leukemic retinopathy caused by CML with leukostasis.

There is a number of literature data on ischemic optic neuropathy development in acute hemorrhage. However, ocular disorders in prolonged chronic hemorrhage and iron-deficiency anemia are not well studied. We present a clinical case of optic nerve and retinal damage in a patient with prolonged chronic gastrointestinal bleeding. 53-year-old patient S. presented with complaints on dramatic sudden loss of vision of his right eye (visual acuity was 0/02 and was not improving with correction). Visual acuity of the left eye was good. Ophthalmoscopy revealed right optic nerve swelling, flame-shaped disc and peripapillary hemorrhages, and multiple soft exudates along blood vessels of the right eye. Optic nerve head of the left eye was pale pink, with well-defined borders. Multiple soft exudates along blood vessels and few flame-shaped hemorrhages were identified as well. Clinical examination revealed iron-deficiency post-hemorrhagic anemia. The diagnosis of anterior ischemic neuropathy of the right eye, ischemic neuroretinopathy of left eye associated with post-hemorrhagic anemia was established. Conservative treatment increased hemoglobin level up to 82 g/l, the red blood cells count - up to 2,88×1012/L, hematocrit was 0.25%, platelet count reached 344×109/L, but the signs of rectal bleeding remained. The patient underwent surgery for hemorrhoids. After the increase of hemoglobin level, visual acuity of the right eye improved to 0.1, the visual acuity of the left eye was 1.0. According to the results of computed peripheral vision test (Humphrey Full Field 120 Point Screening Test), central scotoma and scotomas in the lower half of the field of vision of the right eye remained. In the field of vision of the left eye, the area of absolute arcuate scotoma in the lower-nasal quadrant decreased significantly. Reduced visual acuity was the main complaint of the patient with a longstanding gastrointestinal bleeding. A careful history and thorough clinical examination allowed to establish the cause of the optic nerve and retinal damage, to assign pathogenetically based treatment, which led to an improvement in visual function.

Background: Magnesium valproate is a valproic acid (VPA) derivative that is widely used for the treatment of epilepsy and bipolar disorders. Acute overdose of VPA may cause complicated systemic syndromes; however, the reports of ocular sequelae caused by toxic optic neuropathy (TON) are rare. Case presentation: We present a case of a 19-year-old female with bilateral damage to visual function after acute VPA overdose. She was comatose and received systemic treatments for 1 month, during which she suffered a substantial loss of visual function without any evident neurological sequelae. The first recorded visual acuity was no light perception in the right eye (OD) and hand motion in the left eye (OS). Her best-corrected visual acuity improved to 20/100 OS after 4 months of hyperbaric oxygen therapy and neurotrophic treatments. Her visual field was limited to an inferior nasal area OS. Therefore, a diagnosis of TON was made. Her visual function remained stable in the left eye, but did not recover in the right eye during the 5-month follow-up. We found damage to the optic nerve pathway during ophthalmic examinations. Conclusion: We report a rare case of TON caused by acute VPA overdose. Hyperbaric oxygen therapy, and neuroprotective and neurotrophic treatments might be effective at the early stage but cannot fully reverse the damage to the optic nerve. The present case indicates the potential neurotoxicity of VPA. It is crucial to determine the severity of an isolated optic nerve sequela caused by VPA overdose, though it might be rare as observed in previous reports. Further confirmation of the likelihood of its causation and its pathophysiology is needed in the future.

Additional Information

The advent of optical coherence tomography angiography (OCT-A) provides a new opportunity to visualize the retinal vasculature in a non-invasive and dye-free manner which may help identify vascular abnormalities in glaucoma. While a reduction in retinal and optic nerve head vessel densities and blood flow indexes measured by OCT-A has been demonstrated in patients with glaucoma in many studies, it is unclear whether OCT-A provides additional information for the detection and monitoring of glaucoma compared with OCT measurements such as retinal nerve fiber layer thickness, neuroretinal rim width, and ganglion cell inner plexiform layer thickness. Longitudinal studies are needed to elucidate whether vascular abnormalities detected by OCT-A are a cause or a consequence of optic nerve damage in glaucoma.

Purpose To evaluate the optical coherence tomography angiography (OCT-A) features of a peripapillary intrachoroidal cavitation (ICC) in a patient with high myopia. Methods A 67-year-old woman with ICC underwent visual acuity testing, refraction, slit-lamp biomicroscopy, dilated fundus examination, and OCT-A. The main findings are described in this case report. Results Best-corrected visual acuity was 20/20 in both eyes. Fundus examination revealed in the right eye a macular scar, a tilted disc along with a peripapillary staphyloma, and an orange-yellowish lesion on the inferior border of the disc. Structural OCT B-scan showed ICC as an intrachoroidal hyporeflective space located below the normal plane of the retinal pigment epithelium adjacent to the optic nerve head. Optical coherence tomography angiography showed the cavitation as a hyporeflective area, devoid of detectable flow from the choriocapillaris and large choroidal vessels layers, suggesting the choroid, including the residual hyperreflective tissue in the outer aspect of the retinal pigment epithelium/Bruch membrane, to be avascular in ICC. Conclusions Optical coherence tomography angiography demonstrated the absence of choroidal and choriocapillary network.
