PURPOSE: To report a case treated with therapeutic keratoplasty using a cryo-preserved cornea in a patient with Candida albicans keratitis. CASE SUMMARY: A 77-year-old female visited our clinic because of left ocular pain and visual disturbance for 3 days. Microscopic slit lamp examination revealed a 1.2 mm sized round corneal epithelial defect with deep stromal infiltration, brownish pigmentation and signs of inflammation with cyclitic membranes in the anterior chamber. On suspicion of Candida keratitis, we performed penetrating keratoplasty using a cryo-preserved donor cornea in Optisol-GS® (Bausch & Lomb, Irvine, CA, USA) solution with excision of the infected iris and colony of the anterior chamber. After the procedure, injection of intravitreal or intracameral amphotericin B and voriconazole were administered alternately. At 2 weeks after the second surgery, infection signs disappeared. At the follow-up in the outpatient clinic, signs of infection were not observed. CONCLUSIONS: Therapeutic keratoplasty using a cryo-preserved donor cornea can be an immediate and effective therapeutic strategy for Candida albicans keratitis.

PURPOSE: To evaluate the relation between ocular biometry and anthropometric parameters in Korean adults with cataracts METHODS: The preoperative medical data of 150 eyes (150 patients) who underwent cataract surgery from November 2015 to March 2016. Anthropometric parameters include height, weight and body mass index (BMI). Ocular biometry includes axial length, anterior chamber depth, corneal curvature, lens thickness and central corneal thickness. The relation between ocular biometry and anthropometric parameters was evaluated using linear regression analysis. RESULTS: The mean age was 67.44 ± 10.83 years. The mean height, weight and BMI were 157.24 ± 9.16 cm, 60.50 ± 10.18 kg and 24.47 ± 3.59 kg/m2. The mean axial length, anterior chamber depth, corneal curvature, lens thickness and central corneal thickness were 23.51 ± 0.80 mm, 3.23 ± 0.42 mm, 44.49 ± 1.33 diopter, 4.44 ± 0.42 mm and 534.64 ± 31.90 µm. The height showed a significant positive relationship with axial length and anterior chamber depth and a significant negative relationship with average corneal curvature. However, there was no significant relationship with the central corneal thickness or lens thickness. The weight showed significant positive relationship with axial length. BMI was not related to any anthropometric parameters. Age showed a significant positive relationship with average corneal curvature and lens thickness and a negative relationship with height and anterior chamber depth. CONCLUSIONS: As height increases, the axial length and the anterior chamber depth increase and the corneal curvature become flatter. As age increases, the anterior chamber depth becomes shallower, the corneal curvature becomes steeper and the lens thickness increases.

PURPOSE: To evaluate ocular findings of patients with acute cerebral infarction by analyzing fluorescein angiography (FAG) and optical coherence tomography (OCT). METHODS: We retrospectively reviewed the medical records of patients with acute cerebral infarction. FAG was used to analyze arm to retina time and arteriovenous (AV) transit time. The peripapillary retinal nerve fiber layer (pRNFL) was analyzed using OCT, and the data were compared with those of patients diagnosed with idiopathic epiretinal membrane (control group). RESULTS: Seventy-three patients were included in the patient group, and 56 participants were in the control group. In 27% of the subjects in the patient group, retinal abnormality was incidentally identified. Atrial fibrillation (p < 0.050) was the only systemic disease with a significantly higher incidence in the patient group. AV transit time (p < 0.050) showed a significant delay in the patient group, but there was no significant difference in the arm to retina time. pRNFL thickness did not significantly differ between the ipsilateral and contralateral locations of brain lesion. In addition, there was no significant difference in the subgroup analysis according to cerebral ischemic territory and no correlation between the severity of symptoms and the findings of ophthalmologic examination. CONCLUSIONS: Patients with acute cerebral infarction show delayed AV transit time in FAG, and about 27% of them have unrecognized retinal abnormalities.

Intracranial hypoglossal neurinomas are rare and only about fifty cases have been reported worldwidely. They usually present with hypoglossal nerve palsy preoperatively. The authors experienced, however, two cases of intracranial hypoglossal neurinomas without preoperative hypoglossal nerve palsy. One patient was operated using transcondylar retrosigmoid approach with C1 laminectomy and the other using midline suboccipital craniectomy with C1 laminectomy. Postoperatively hypoglossal nerve palsy was developed in both cases. Absence of preoperative hypoglossal palsy seemed to be related to somewhat different growth pattern in these two cases. When the tumor shows typical radiological findings of hypoglossal neurinoma, it must be included in differential diagnosis despite absence of preoperative hypoglossal nerve palsy.

PURPOSE: To evaluate the efficacy of anterior segment swept-source optical coherence tomography (SS-OCT) for examining horizontal extraocular muscle thickness, distance from the corneal limbus to the insertion of the horizontal extraocular muscle (limbus to insertion distance), and scleral thickness in Korean pediatric strabismus patients. METHODS: This study included pediatric strabismus patients between 5 and 10 years of age. Children with any ocular disease other than strabismus or a history of ocular surgery were excluded. SS-OCT was used to measure horizontal extraocular muscle thickness, limbus to insertion distance, and scleral thickness. Eyes were classified into subgroups by sex, spherical equivalent of the refractive error (measured with cycloplegic refraction), and fixating/deviating eye. RESULTS: One patient initially included in this study was excluded due to poor cooperation. Of the remaining 35 eyes of 20 patients, 19 eyes (54.3%) were from male patients and 16 eyes (45.7%) were from female patients. The mean patient age was 7.86 ± 1.38 years. Lateral scleral thickness was greater in male eyes than in female eyes (p = 0.048). No other differences were noted between male and female children. Additionally, there were no statistically significant differences between fixating and deviating eyes or among spherical equivalent groups for any parameter examined. CONCLUSIONS: Anterior segment SS-OCT can successfully and comfortably measure horizontal extraocular muscle and scleral anatomy in children. These measurements may be helpful for treatment and follow-up of pediatric strabismus patients.

Extranodal Natural Killer (NK)/T-cell lymphoma, nasal type, is a subtype of non-Hodgkin lymphoma, strongly associated with Epstein-Barr virus. Extranodal NK/T-cell lymphoma mostly affects the nasal cavity and there has been no report of the disease’s occurrence at the base of tongue. Here we report a case of 43-year-old man who presented with a diffuse ulcerative lesion at the base of tongue. Because the patient had oral bleeding, tracheostomy and lingual artery ligation was performed via a transcervical approach to control bleeding and protect the upper airway. We performed a deep biopsy through the lateral pharyngotomy approach, and finally, the patient was diagnosed with extranodal NK/T-cell lymphoma, nasal type. We report this rare case of extranodal NK/T cell lymphoma at the base of tongue with a literature review.

OBJECTIVE: Traditionally, it is generally recommended that antiplatelet agent should be discontinued before surgery. However, decompressive craniectomy (DC) in patients with traumatic brain injury (TBI) is performed emergently in most cases. Therefore, DC cannot be delayed to the time when the effect of antiplatelet agent on bleeding tendency dissipates. In this study, we evaluated the effect of preinjury antiplatelet therapy on hemorrhagic complications after emergent DC in patients with TBI. METHODS: We retrospectively investigated patients with TBI who underwent emergent DC between 2006 and 2015. The patients were separated into two groups according to the use of preinjury antiplatelet agent: group 1 (patients taking antiplatelet agent) and group 2 (patients not taking antiplatelet agent). The rate of hemorrhagic complications (postoperative epidural or subdural hemorrhage, newly developed, or progression of preexisting contusion or intracerebral hemorrhage within the field of DC) and the rate of reoperation within 7 days after DC were compared between two groups. RESULTS: During the study period, DC was performed in 90 patients. Of them, 19 patients were taking antiplatelet agent before TBI. The rate of hemorrhagic complications was 52.6% (10/19) in group 1 and 46.5% (33/71) in group 2 (p=0.633). The rate of reoperation was 36.8% (7/19) in group 1 and 36.6% (26/71) in group 2 (p=0.986). No statistical difference was found between two groups. CONCLUSION: Preinjury antiplatelet therapy did not influence the rate of hemorrhagic complications and reoperation after DC. Emergent DC in patients with TBI should not be delayed because of preinjury antiplatelet therapy.

The molecular mechanisms control the function of PDL(periodontal ligament) cells and/or fibroblasts remain unclear. PDLs17, PDL-specific gene, had previousely identified the cDNA for a novel protein from cultured PDL fibroblasts using subtraction hybridization between gingival fibroblasts and PDL fibroblasts. The purpose of this study was to determine the regulation by growth factors and cytokines on PDLs17 gene expression in cultured human periodontal ligament cells and observe the immunohistochemical localization of PDLs17 protein in various tissues of mouse. Primary PDL fibroblasts isolated by scraping the root of the extracted human mandibular third molars. The cells were incubated with various concentration of human recombinant IL-1beta, PDGF-BB and TGF betafor 48h and 2 weeks. At each time point total RNA was extracted and the levels of transcription were assessed by reverse transcription-polymerase chain reaction (RT-PCR assay). Polyclonal antiserum raised against PDLs17 peptides, CLSVSYNRSYQINE and SEAVHETDLHDGC, were made, and stained the tooth, periodontium, developing bone, bone marrow and mid-palatal suture of the mouse. The results were as follows. 1. PDLs17 mRNA levels were increased in response to PDGF (10ng/ml) and TGF beta(20ng/ml) after treatment of the IL-1beta, PDGF-BB and TGFbetafor 48 h. 2. PDLs17 was up-regulated only by TGFbeta(20 ng/ml) after treatment of the IL-1beta, PDGF-BB and TGF betafor 2 weeks and unchanged by the other stimulants. 3. PDLs17 was a novel protein coding the 142 amino acid peptides in the ORF and the nucleotide sequences of the obtained cDNA from RT-PCR was exactly same as the nucleotides of the database. 4. Immunohistochemical analysis showed that PDLs17 is preferentially expressed in the PDL, differentiating osteoblast-like cells and stromal cells of the bone marrow in the adult mouse. 5. The expression of PDLs17 protein was barely detectable in gingival fibroblasts, hematopoetic cells of the bone marrow and mature osteocytes of the alveolar bone. These results suggest that PDLs17 might upregulated by PDGF-BB or TGFbetaand acts at the initial stage of differentiation when the undifferentiated mesenchymal cells in the bone marrow and PDL differentiate into multiple cell types. However, more research needs to be performed to gain a better understanding of the exact function of PDLs17 during the differentiation of bone marrow mesenchymal and PDL cells.
