RESUMO
Purpose@#This study aimed to identify the etiology and risk factors of community-acquired pneumonia (CAP) requiring hospitalization in Korean children during the coronavirus disease 2019 (COVID-19) pandemic. @*Methods@#Clinical information of children admitted with CAP to Seoul National University Children’s Hospital (SNUCH) between January 1, 2021, and February 28, 2022, was retrospectively collected and analyzed. In addition, the etiologic diagnosis and demographic data of children with CAP who were discharged at the other seven hospitals between January and February 2022 were collected. Pneumonia was diagnosed using strict criteria comprising clinical symptoms, physical examination findings, and chest radiographic findings. @*Results@#Among 91 children hospitalized with CAP at SNUCH during the 14-month period, 68.4% were aged <5 years and 79.1% had underlying diseases. Among the 95 CAP cases, respiratory assistance was required in 70.5%, and the use of a ventilator was required in 20.0%.A total of five patients expired, all of whom were either immunocompromised or had underlying neurological diseases. Neurological diseases and immunosuppression were significantly correlated with respiratory assistance (P=0.003) and death (P=0.014). A total of 55% of the detected respiratory pathogens were viruses, the most common of which was rhinovirus at 35.9%. Among the 169 children hospitalized for CAP at the eight institutions, ≥1 respiratory virus was detected in 92.3%, among which respiratory syncytial virus (79.8%) was the most prevalent. @*Conclusions@#Even during the COVID-19 pandemic, Korean children were hospitalized with CAP caused by seasonal respiratory viral pathogens. Although atypical and pyogenic bacteria were not detected, continuous clinical monitoring and further prospective studies should be conducted.
RESUMO
A 52-yr-old male was referred for progressive visual loss in the left eye. The decimal best-corrected visual acuity (BCVA) was 0.01. Fundus examination revealed diffuse retinal pigment epithelial degeneration, focal yellow-white, infiltrative subretinal lesion with fuzzy border and a live nematode within the retina. Diffuse unilateral subacute neuroretinitis (DUSN) was diagnosed and the direct laser photocoagulation was performed to destroy the live nematode. During eight months after treatment, BCVA gradually improved to 0.2 along with the gradual restoration of outer retinal layers on SD-OCT. We report on the first case of DUSN in Korea. DUSN should be included in the differential diagnosis of unexplained unilateral visual loss in otherwise healthy subjects.

This case describes the reversal of early central retinal vein occlusion (CRVO) with disc swelling after intravitreal dexamethasone implant (Ozurdex) injection. A 44-year-old female presented with sudden-onset intermittent blurred vision in her left eye. Fundus examination revealed multiple retinal hemorrhages without macular edema (ME). Two weeks later, an increased number of retinal hemorrhages with severe disc swelling were noted with still no sign of ME. An intravitreal dexamethasone implant was injected. Five days later, there were improvements in disc swelling and retinal hemorrhage. One month later, her subjective visual symptoms were completely improved, and fundus examination revealed marked improvement along with almost complete resolution of disc swelling. Intravitreal dexamethasone implant injection may potentially change the natural course of CRVO progression and its various subsequent complications.

A 5-year-old girl was diagnosed with neurofibromatosis type 2 (NF-2) due to multiple neurofibromas, cafe-au-lait spots, and schwannomas of the brain. During ophthalmologic evaluation, a posterior subcapsular cataract and a gray-green colored subretinal lesion were found in right eye. Fluorescein angiography (FA) revealed a combined hamartoma of the retina and retinal pigment epithelium (CHRRPE). At age 9, she underwent cataract surgery. At this time FA and spectral-domain optical coherence tomography (SD-OCT) were taken. The SD-OCT showed an elevated hyperreflective mass in the retina with prominent attenuation of the inner and outer retina, but minimal attenuation in the photoreceptor layers. The underlying retina appeared to be disorganized and thick (791 microm). This is the first case report of SD-OCT imaging of a CHRRPE associated with NF-2 in a pediatric patient. By using SD-OCT in this patient, we could obtain detailed tumor characteristics, and SD-OCT may be helpful in the diagnosis and management of CHRRPE.

PURPOSE: To describe the clinical manifestations and magnetic resonance imaging (MRI) characteristics of idiopathic optic perineuritis patients in Korea. METHODS: A retrospective chart review of 5 patients (6 eyes) with idiopathic optic perineuritis and 7 patients (7 eyes) with optic neuritis was performed. RESULTS: The mean age of the 5 patients with idiopathic optic perineuritis was 59 years, and the mean age of the 7 patients with optic neuritis was 31.1 years. A relative afferent papillary defect (RAPD) was present in 4 eyes with idiopathic optic perineuritis, and in all 7 eyes with optic neuritis. All six eyes with idiopathic optic perineuritis showed relatively severe optic disc swelling, and 6 eyes with optic neuritis showed mild optic disc swelling. MRI demonstrated optic nerve sheath enhancement in all patients with idiopathic optic perineuritis and optic nerve enhancement in six patients with optic neuritis. CONCLUSIONS: On MRI, compared with optic neuritis, idiopathic optic perineuritis had a higher onset age, relatively severe optic disc swelling, and optic nerve sheath enhancement. Because idiopathic optic perineuritis is known to have different treatment strategies and prognosis compared with optic neuritis, differential diagnosis is crucial. The clinical manifestations and MRI characteristics of idiopathic optic perineuritis in the present study will help in the diagnosis of Korean patients.

PURPOSE: Compared with multiple cranial nerve palsies, isolated nerve palsy is very rare in Non-Hodgkin's lymphoma. We experienced a case of isolated oculomotor nerve palsy as the first sign of recurrent diffuse large B-cell lymphoma (DLBCL). CASE SUMMARY: A 45-year-old woman visited the ophthalmology clinic with a one-month history of left upper eyelid ptosis and diplopia. She had a history of DLBCL of the nasopharynx and has been in complete remission for three years after systemic chemotherapy. Ophthalmologic evaluation showed ptosis of the upper eyelid, anisocoria, but no definite limitations in ocular movement. After six weeks, aggravated ptosis, exodeviation of the left eye in the primary position, and ocular movement limitations in all directions except abduction were observed. Brain magnetic resonance angiography taken four weeks earlier demonstrated no intracranial vascular lesion, but an enhancing lesion in the cistern along the left oculomotor nerve was shown in brain magnetic resonance imaging. We diagnosed isolated oculomotor nerve palsy due to direct invasion of recurrent DLBCL. Cerebrospinal fluid analysis revealed tumor cells, and follow-up MRI showed progression of lymphoma into the cavernous sinus. CONCLUSIONS: Although not common, isolated oculomotor nerve palsy can be the first sign of malignant lymphoma, even after complete remission.

An 11-year-old female presenting diplopia only at distance was found to have comitant esotropia of 20 prism diopters (PD) at distance and normal alignment at nearer proximity. Other ocular movement, including abduction, was normal and a thorough neurologic examination was also normal. The deviation angle of esotropia was increased to 35 PD in 6 months, and a brain magnetic resonance imaging with venogram at that time demonstrated no intracranial lesion. A lumbar puncture showed increased opening pressure but the cerebrospinal fluid composition was normal. The patient was diagnosed as having idiopathic intracranial hypertension and treated with oral acetazolamide. Three months after treatment, the deviation angle decreased to 10 PD. This is a case report of divergence insufficiency in pediatric idiopathic intracranial hypertension, with an increasing deviation angle of esotropia. Although sixth cranial nerve palsy is a common neurologic manifestation in intracranial hypertension, clinicians should be aware of the possibility of divergence insufficiency. Also, ophthalmoparesis may not be apparent and typical at first presentation, as seen in this case, and therefore ophthalmologists should be aware of this fact, while conducting careful and proper evaluation, follow-up, and intervention.

A 54-year-old male patient was seen in clinic for ocular pain and decreased vision in the right eye with duration of two days. He underwent a cataract operation for his right eye 12 years ago, then a sclera-fixated secondary intraocular implantation and pars plana vitrectomy three years ago due to intraocular lens dislocation. At the initial visit, his visual acuity was restricted to the perception of hand motion. An edematous cornea, cells, flare with hypopyon, and exposed suture material at were observed at the six o'clock direction by slit lamp. Vitreous opacity was noted from B-scan ultrasonography. The patient was diagnosed with late-onset endophthalmitis and an intravitreal cocktail injection was done. On the next day, the hypopyon was aggravated, and therefore a pars plana vitrectomy was performed. A vitreous culture tested positive for Citrobacter koseri. After 12 weeks, the best corrected visual acuity of the right eye improved to 0.7 and a fundus examination revealed a relatively normal optic disc and retinal vasculature. We herein report the first case of endophthalmitis caused by Citrobacter koseri in Korea. Exposed suture material was suspected as the source of infection in this case and prompt surgical intervention resulted in a relatively good visual outcome.

A 60-year-old male was referred to the ophthalmologic clinic with aggravated anterior uveitis and corneal edema despite the use of topical and systemic steroids. He had undergone cataract surgery in both eyes 15 years previous. Slit lamp examinations revealed a retained lens fragment in the inferior angle of the anterior chamber, with severe corneal edema and mild anterior uveitis. The corneal edema and uveitis subsided following surgical extraction of the lens fragment. That a retained lens fragment caused symptomatic anterior uveitis with corneal edema 15 years after an uneventful cataract surgery is unique. A retained lens fragment should be considered as one of the causes of anterior uveitis in a pseudophakic patient.
