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.

Liver Injuries

Liver injuries caused by high voltage electricity are rare and result in high mortality and morbidity. They are produced by the resistance to the passage of electrical current through the tissue, which creates heat that leads to coagulation necrosis and rupture of the cell membrane. We present a case of an electrical injury to the liver, diagnosed by ultrasound and CT in a 39-year-old man who presented with skin burns on his right hand and right hemiabdomen. Injuries occurred after the contact with 220 kV high voltage electricity.

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.

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.

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.

Electrical Injuries

Though responsible for just 4% of burn centre admissions, electrical injuries present in a myriad of ways. From small, innocuous, partial-thickness injuries on the fingertip, to a high-voltage injury requiring amputation and complex reconstruction, the burn surgeon must be equipped with the knowledge and skill to deal with such varying injuries. This chapter describes the epidemiology of electrical injury and the pathophysiology of electrical current passing through the patient. The management of high- and low-voltage wounds is described, as is the treatment of the systemic effects of the electrical injury.

Twenty-six-year-old male patient admitted to the outpatient clinic with a complaint of decreased vision in both eyes. Visual acuity was 2/10 in the right and 7/10 in the left eye. Fundus examination revealed bilateral yellow-white subretinal lesions involving the macula. Fluorescein angiography showed hypofluorescent lesions in early and hyperflourescent lesions in the late phase. Optical coherence tomography angiography performed in the acute phase showed bilateral hypofluorescency at the choriocapillary level. A diagnosis of acute posterior multifocal placoid pigment epitheliopathy was given. After steroid treatment, visual acuity was improved to 10/10 and earlier lesions in optical coherence tomography angiography were found to be reduced. In conclusion, optical coherence tomography angiography is a noninvasive imaging technique that can be used in the diagnosis and follow-up of acute posterior multifocal placoid pigment epitheliopathy.

Abstract Background Choroidal osteoma is a benign intraocular tumor that can increase risk of developing choroidal neovascularization. The visual prognosis is influenced by the tumor location, decalcification status, overlying RPE atrophy, presence of choroidal neovascularization, persistence of subretinal fluid and occurrence of subretinal hemorrhages. Case presentation The authors present a 40-year-old woman diagnosed with choroidal osteoma of the right eye. Her best corrected visual acuity was 12/20 but decreased to 5/20 due to secondary choroidal neovascularization after 8 years follow up. Fundus examination revealed an enlarged choroidal osteoma in most margins at posterior pole with schistose hemorrhage beside macula. Optical coherence tomography angiography revealed unique features in the vascular changes of choroidal neovascularization in choroidal osteoma in the outer retinal layer and choroid capillary layers, and subretinal neovascularization. Indocyanine green fluorescence angiography showed there was hypo-fluorescence at the peripapillary with faint hyper-fluorescence at the macular, corresponding to the location on the fundus photograph. The patient received 3 injections of intravitreal ranibizumab. After 1 year follow up, her visual acuity of the right eye was 18/20 and the CNV had regressed. Conclusions We present the findings and treatment of a case of choroidal osteoma with secondary choroidal neovascularization. Optical coherence tomography angiography combined with FFA and ICGA is used to analysis the characteristics of secondary choroidal neovascularization. Optical coherence tomography angiography can reveal some unique characteristics in the vascular changes compared to fundus fluorescein angiography.
