ABSTRACT
Purpose@#To report a case of diffuse large B-cell lymphoma of the conjunctival fornix.Case summary: A 49-year-old man visited our clinic with redness and foreign body sensation in the right inferior conjunctival fornix that had begun 20 days previously. The patient had no pain, no fever, weight loss, and no past history of chronic disease. On slit lamp biomicroscopic examination, a large, salmon-colored, raised, well-defined, mass was detected in the inferior bulbar and fornix conjunctiva. We performed excision biopsy. The soft tissue lesion was 17 × 5 × 4 mm in size. Microscopic examination identified an area of small, mature mononuclear lymphocytes and an area of lymphocytes, such as large lymphoblasts with divided nuclei and conspicuous nucleoli. On immunohistochemical staining, the diffuse large B-cell lymphoma areas were positive for CD20 and Bcl-6, negative for CD3, CD5, and CD23, and the Ki-67 positive rate was relatively high. Finally, the patient was diagnosed with diffuse large B-cell lymphoma accompanying mucosal-associated lymphoid tissue lymphoma. There were no findings suggestive of metastasis invasion from other organs. The patient underwent immunochemotherapy after excisional biopsy. No recurrence has occurred over 1-year follow-up. @*Conclusions@#Although rare, diffuse large B-cell lymphoma should be considered in the differential diagnosis of conjunctival lymphomatous lesions.
ABSTRACT
There are several reports that herpes zoster characterized by reactivation of varicella zoster virus (VZV) following coronavirus disease 2019 (COVID-19) vaccines can occur. Herein, we report VZV meningitis, herpes zoster ophthalmicus (HZO), and late neurotrophic keratitis after receiving a second dose of messenger RNA (mRNA) COVID-19 vaccine. A 74-year-old man developed a vesicular skin rash on the forehead, scalp, nose, and left upper eyelid with a severe headache. Five days earlier, he received a second dose of the BNT162b2 mRNA vaccine on his left arm. Ocular examination revealed conjunctival hyperemia and pseudodendrite in the peripheral cornea. VZV was detected in the cerebrospinal fluid using polymerase chain reaction. The patient was diagnosed with HZO and meningitis. The patient was treated with intravenous acyclovir and topical acyclovir ointment and levofloxacin 1.5% eye drops.One month later, he developed a central epithelial defect with a rolled margin, typical of a neurotrophic ulcer. Treatment with a therapeutic contact lens and a combination of topical recombinant human epithelial growth factor and ofloxacin ointment was initiated. At six months after vaccination, the slit-lamp examination findings were stable with a mild corneal superficial stromal haze.
ABSTRACT
Purpose@#To report a case of ocular and facial herpes zoster and meningitis after herpes zoster vaccination.Case summary: A 60-year-old man was administered Zostavax® on his left arm; he developed a vesicular rash over his left eye and forehead 4 days afterwards. He started antiviral drugs for the rash, and visited the hospital for severe headache and spread of the rash to involve the tip of his nose, face, and palate by day 7. He was taking Synthyroid® (Bukwang Pharmaceuticals, Seoul, Korea) since his thyroidectomy for thyroid cancer 6 years ago. He had never been diagnosed with chickenpox, but had an episode of red facial rash in childhood. Slit-lamp examination revealed conjunctival chemosis, hyperemia, and a pseudodendrite in the peripheral cornea. The anterior chamber was quiet, and there were no significant findings on his brain magnetic resonance imaging. Varicella zoster virus was detected in the cerebrospinal fluid by polymerase chain reaction. The patient was treated with oral acyclovir drugs and topical ganciclovir, levofloxacin, and bromfenac. One week later, the pseudodendrite disappeared and conjunctival chemosis improved. There was no recurrence during 6 months follow-up. @*Conclusions@#Reactivation of ocular or facial herpes zoster or meningitis after zoster vaccination may occur, rarely. Immediate antiviral treatment is required in these cases.
ABSTRACT
Purpose@#To describe the clinical manifestations, causative organisms, treatment, and prognostic factors of fungal keratitis based on analysis of patients over the past 20 years. @*Methods@#A total of 177 patients (177 eyes) with fungal keratitis, who were diagnosed by smears and cultures, were reviewed retrospectively. Sex, age, predisposing factors, causative organisms, clinical manifestations, treatment, and prognosis were evaluated. The patients were divided into three groups: only potassium hydroxide (KOH)-positive, only culture-positive, and KOH- and culture-positive. Logistic regression was performed to identify the factors associated with a poor clinical outcome. @*Results@#The mean age of the patients was 67.4 ± 11.3 years; 107 (60.5%) patients were men. The most common predisposing factor was ocular trauma (57.6%), especially by plants (29.4%). The most prevalent filamentous fungi were Fusarium species (31.6%, 49 isolates), and the most prevalent yeasts were Candida species (11.0%, 17 isolates). In cases of bacterial and fungal keratitis, filamentous fungus with Gram-positive bacterial infection (70.7%, 29/41) was the most common presentation. Visual improvement after treatment was common in the KOH-positive group (79.2%, 19/24), while visual deterioration after treatment was common in the culture-positive group (40.4%, 36/89). Previous ocular disease (odds ratio [OR]: 3.744, p = 0.010), hypopyon (OR: 2.941, p = 0.030), and surgical treatment (OR: 24.482, p < 0.001) were risk factors for a poor clinical outcome in the multivariate logistic regression model. @*Conclusions@#Clinical prognosis was good in the KOH-positive only group, but poor in the culture-positive group. If fungal keratitis is suspected, diagnostic KOH staining and culture tests should be performed initially. Early intensive antifungal medical treatments are necessary for patients with risk factors for poor clinical outcomes.
ABSTRACT
Purpose@#To analyze the clinical manifestations of culture-proven infective keratitis patients over a recent 10-year period. @*Methods@#We retrospectively reviewed the medical records of 956 cases of infective keratitis between January 2008 and December 2017 at eight tertiary hospitals. The study was performed to analyze the risk factors, causative microbial organisms, therapeutic outcomes, and prognosis. @*Results@#The most common risk factor of keratitis was trauma (33.2%). Initial visual acuity (V/A) was finger count or less in 449 eyes (47.0%). The common location of keratitis was central, and the size was 4 mm2 or less. Hypopyon was observed in 295 eyes (30.9%). Of the 1,039 cultured isolates, 443 (42.6%) grew Gram-negative bacteria with the most common being Pseudomonas aeruginosa. The most prevalent Gram-positive bacteria was Staphylococcus epidermidis, and fungi was Fusarium species. Surgical treatments were performed in 201 eyes (21.0%), followed by amniotic membrane transplantation (66 eyes) and evisceration (44 eyes). Final V/A was 20/100 or more in 422 eyes (44.1%). Gram-positive organisms were highly susceptible to moxifloxacin and vancomycin, and Gram-negative organisms were highly susceptible to levofloxacin and ceftazidime. An increase in resistance to these antibiotics was detected for Enterococcus and Pseudomonas. @*Conclusions@#In South Korea, infective keratitis occurs frequently in eyes with trauma. Staphylococcus epidermidis, Pseudomonas aeruginosa, and Fusarium species are commonly identified etiologies of microbial keratitis. The appropriate administered medical and surgical treatments of suspected infectious keratitis can lead to visual improvement with particular care taken to minimize infection related to resistant bacteria and fungal microbes as needed. An initial V/A of 0.02 or less, the presence of hypopyon, age of 65 years or more, and a central lesion were associated with poor clinical outcome of bacterial keratitis. Age of 70 years or more was a significant risk factor for poor clinical outcome of fungal keratitis.
ABSTRACT
Purpose@#To report a case of bilateral subepidermal calcified nodules of the upper eyelid in a child.Case summary: A 5-year-old girl with no history of trauma or systemic disease was referred for assessment of bilateral eyelid masses that had appeared 8 months prior. The masses grew slowly without pain, and were hard, elevated, and yellowish-white in color. The right eyelid mass was close to the medial canthus and measured 0.2 × 0.2 cm. The mass of the left upper eyelid was smaller (0.2 × 0.1 cm) and closer to the medial side. The clinical impression was juvenile xanthogranuloma and molluscum contagiosum. Excisional biopsy of the bilateral eyelid masses was performed. Histologic findings revealed that the lesions were composed of variable-sized multiple calcium deposits, lined by hyperplastic and hyperkeratotic epidermis or within the hyperkeratotic epidermis. The diagnosis was subepidermal calcified nodules (SCNs) for both of the bilateral eyelid masses. The patient made a complete recovery after the excision, without recurrence. @*Conclusions@#SCNs should be considered during differential diagnosis of a painless, elevated, yellowish-white eyelid lesion.

ABSTRACT
Purpose@#To report a case of congenital trichomegaly.Case summary: A 7-year-old girl visited our clinic with decreased visual acuity. The uncorrected visual acuity was 0.2 in the right eye and 0.3 in the left eye. The length and number of upper and lower eyelashes were increased. The eyelash length was 10 mm on the peripheral edge and 15 mm in the central area. Trichiasis and ptosis were also noted. There were no abnormal findings in the additional fundus examination or visual evoked potential test. There was no family history of trichomegaly, no abnormalities in blood test results, and no medication history. The patient is currently undergoing follow-up treatment for low visual acuity and mild ptosis under the diagnosis of trichomegaly. @*Conclusions@#Trichomegaly is associated with family history, various congenital diseases, and acquired diseases. However, it may occur congenitally, without specific causes.
ABSTRACT
PURPOSE: To evaluate the effect of oral spironolactone for non-resolving chronic central serous chorioretinopathy after intravitreal bevacizumab injection.METHODS: Seventeen eyes of 17 patients with non-resolving chronic central serous chorioretinopathy after intravitreal bevacizumab injection from September 2017 to December 2018 were treated with oral spironolactone for 6 months, and changes in central macular thickness, subretinal fluid height, and best-corrected visual acuity (BCVA) were analyzed retrospectively.RESULTS: The central macular thickness decreased from 309.94 ± 105.20 µm at baseline to 259.76 ± 81.83 µm at 3 months, and 243.11 ± 61.98 µm at 6 months, which were both statistically significant (Wilcoxon signed-rank test, p = 0.016 and p = 0.001, respectively). The subretinal fluid height decreased from 138.05 ± 95.69 µm at baseline to 70.88 ± 83.13 µm at 3 months, and 54.00 ± 56.25 µm at 6 months, which were both statistically significant (Wilcoxon signed-rank test, p = 0.002 and p = 0.000, respectively). The BCVA (LogMAR) changed from 0.30 ± 0.38 at baseline to 0.35 ± 0.43 at 1 month, 0.29 ± 0.43 at 3 months, and 0.26 ± 0.40 at 6 months. The results at 6 months were statistically significant (Wilcoxon signed-rank test, p = 0.033). There were no side effects in patients treated with oral spironolactone.CONCLUSIONS: In chronic central serous chorioretinopathy, treatment with oral spironolactone significantly reduced the central macular thickness, subretinal fluid height, and the BCVA, without side effects.
ABSTRACT
PURPOSE@#To report a case of unilateral loss of reflex tearing after double-jaw surgery with anatomy and mechanism.CASE SUMMARY: A 32-year-old woman complained of a 3-year history of loss of tearing in her left eye. She had undergone double-jaw surgery 3 years prior to correct her malocclusion. In orbital computed tomography (CT) images, there were no specific findings, with the exception of a fractured left pterygoid plate, possibly caused by the double-jaw surgery. The tear break-up times of both eyes were similar, with non-specific findings on slit lamp examination. We diagnosed loss of reflex tearing due to pterygopalatine ganglion injury based on her history, physical examination and orbital CT findings.@*CONCLUSIONS@#Nerve damage due to artificial fracture may occur during double-jaw surgery and may result in loss of reflex tearing, thus, pre-operative evaluation of basic lacrimal secretion and a reflex tearing test are important. Once the loss of reflex tearing due to nerve injury occurrs, orbital CT scans are needed for diagnosis. Ophthalmologist examination is necessary to confirm the mechanism of loss of reflex tearing and changes in the anatomical structure.
ABSTRACT
PURPOSE: To investigate the efficacy and factors affecting the success rates of nasolacrimal probing and silicone intubation (SI) in patients with congenital nasolacrimal duct obstruction (CNLDO). METHODS: We retrospectively reviewed the medical records of patients including 69 eyes of 59 patients who received probing and 61 eyes of 49 patients who received SI. In patients with probing, the age, sex, and history of conservative treatment were analyzed in the success and failure groups, and a success rate comparison was conducted by dividing these values into postnatal group 1 ( 12 months, the success rate of probing was lower than in patients 12 months.

PURPOSE: To report a case of a Corynebacterium macginleyi-infected corneal ulcer of a patient who had been treated for conjunctivitis for more than 3 months. CASE SUMMARY: A 72-year-old female was transferred from a private ophthalmic clinic for evaluation of herpetic keratitis with progressive corneal edema and infiltration in the left eye. She had a history of conjunctival hyperemia and eyeball pain in her left eye 3 months prior to her visit. She was treated with levofloxacin eye drops and acyclovir ointment (Herpesid®, Samil, Co., Ltd. Seoul, Korea). On slit lamp examination, 5.4 × 4.0 mm corneal epithelial defects and stromal infiltrations were observed in the upper to central cornea, and endothelial keratic precipitates were found. Gram positive bacteria were detected on Gram staining and Corynebacterium macginleyi was identified on bacterial cultures from the conjunctiva and cornea. She was treated with topical vancomycin eye drops. After 3 months of treatment, the corneal ulcer was completely resolved, leaving mild superficial opacity on the cornea. CONCLUSIONS: While Corynebacterium macginleyi, normal flora of the conjunctiva, is considered a major causative agent for conjunctivitis and blepharitis, Corynebacterium macginleyi should also be considered a possible cause of slowly progressive keratitis in patients with chronic conjunctivitis.

PURPOSE: The purpose of this study was to investigate the effect of bilateral medial rectus muscle resection on the treatment of recurrent intermittent exotropia. METHODS: A retrospective chart analysis was conducted for 25 patients who underwent bilateral medial rectus resection for recurrent exotropia over 20 prism diopters (PD) between January 2009 and August 2015. The medial rectus was resected from 4.0 to 6.5 mm by 0.5 mm according to the deviation angle. The postoperative angle of deviation was checked at 1 day, 1 week, 3 months, 6 months, and 1 year postoperatively to investigate the amount of corrected deviation per resected muscle. RESULTS: The average preoperative deviation angle was 27.20 ± 5.02 PD exodeviation and the mean resection was 5.10 ± 0.79 mm of the medial rectus. The postoperative angle deviation was 10.68 ± 5.50 PD esodeviation at 1 day. The incidence of esodeviation tended to decrease over time. At 1 year, the postoperative angle deviation was 1.16 ± 7.54 PD esodeviation. The overcorrection rate was 84% at 1 day postoperatively but decreased to 24% at 1 year with a success rate of 68%. The corrected deviation angle per millimeter was 7.53 ± 1.22, 7.75 ± 2.16, 6.27 ± 1.74, 5.50 ± 1.54, and 5.56 ± 1.58 PD/mm at 1 day, 1 week, 3 months, 6 months, and 1 year after surgery, respectively. The dose effect per millimeter decreased over time. The corrected deviated angle per millimeter remained constant regardless of the amount of medial rectus muscle resection at 1 year postoperatively(p=0.939). CONCLUSIONS: Bilateral medial rectus resection for recurrent exotropia over 20 PD tended to overcorrect at first; however, after 1 year, the mean angle of deviation was 1.16 ± 7.54 PD esodeviation. Bilateral medial rectus resection is an effective surgical method for the treatment of recurrent exotropia over 20 PD.

PURPOSE: To investigate the correlation between en face optical coherence tomography and improvements in the postoperative prognoses of idiopathic epiretinal membranes. METHODS: The medical records of 59 epiretinal membrane patients who had epiretinal membrane peeling between January 2005 and January 2016, and were followed up for > 12 months, were retrospectively reviewed. The preoperative en face images were divided into four sections involving three circular areas (6,000 µm diameter circle, 3,000 µm diameter circle, and 1,000 µm diameter circle) and one square (6,000 × 6,000 µm). The surface area where no epiretinal adhesion was present was quantified by measuring the number of black pixels using image-editing software (Adobe Photoshop CS6, Adobe Systems, San Jose, CA, USA). Then the correlations among the value of black pixels, preoperative and postoperative visual acuities, and central retinal thickness were analyzed. RESULTS: The best-corrected visual acuity (BCVA) was significantly increased after epiretinal membrane peeling (p < 0.001), and the central retinal thickness was significantly decreased (p < 0.001). As the number of black pixels in the circles and the square in the en-face images increased, the postoperative BCVA significantly increased (r = 0.645, p < 0.001; r = 0.590, p < 0.001, respectively). CONCLUSIONS: As the nonadhesive surfaces of the epiretinal membrane and the retina in preoperative en face images became wider, the increments of the BCVA after surgery were greater. Therefore, en face optical coherence tomography can be used to predict prognosis after epiretinal membrane peeling.

A 74-year-old man presented with pain and progressively worsening vision from 20 days ago in the left eye. His ophthalmological history was significant for cataract extraction, scleromalacia, and three surgeries for pterygium removal in the left eye. Slit-lamp examination was remarkable for a 4.5×4.0 mm sized epithelial defect, with corneal stromal infiltration and melting and a surrounding feathery margin. Corneal scraping was performed, and culture of specimen demonstrated mold that grew on Sabouraud dextrose agar. The isolate was finally identified as Corynespora cassiicola based on DNA sequencing analysis of internal transcribed spacer (ITS) with maximum identity of 100%. The patient was treated successfully with intracameral amphotericin B injection and topical voriconazole and amphotericin B. To the best of our knowledge, this is the first reported case of mycotic keratitis caused by a plant pathogen, Corynespora cassiicola, in Korea.
ABSTRACT
PURPOSE: The purpose of this study is to make a distinction between tuberculous serpiginous-like choroiditis and serpiginous choroiditis, and compare their clinical manifestations. METHODS: We retrospectively reviewed thirty eight eyes of twenty-six patients who visited our institution and were diagnosed with serpiginous choroiditis from January 2005 to December 2014. The patients were divided into two groups, tuberculosis serpiginous- like choroiditis (Tb-SLC) and classic serpiginous choroiditis (classic SC), and were analyzed based on the treatment response, previous history of Bacillus Calmette–Guérin (BCG) vaccination, positive results of tuberculin skin test (TST), chest X-ray, anterior and fundus examination, and fluorescein angiography (FAG). RESULTS: Twenty seven eyes of eighteen patients were serpiginous choroiditis and eleven eyes of eight patients were tuberculosis serpiginous-like choroiditis. There were no significant differences in age, sex, or previous history of BCG vaccination between the two groups. The positive result of the tuberculin skin test and abnormality in the chest X-ray were shown to be significantly higher in the Tb-SLC group. Multi-focal lesions involving periphery observed in fundus examination and FAG were significantly higher in Tb-SLC. CONCLUSIONS: In tuberculosis endemic areas such as Korea, tuberculosis serpiginous-like choroiditis should be considered as a differential diagnosis when the patient is suspicious of serpiginous choroiditis. The understanding of various clinical manifestations of tuberculosis serpiginous-like choroiditis may derive accurate diagnosis and treatment, enhancing patient's prognosis.
