PURPOSE: To evaluate the factors contributing to the visual outcome of patients with culture-proven bacterial endophthalmitis. METHODS: We reviewed medical records of all eyes with infectious endophthalmitis between January 1996 and June 2005. The causative bacteria were identified in 18 of 90 eyes, for which we evaluated their clinical features and factors influencing their visual prognosis. RESULTS: Bacterial endophthalmitis occurred after cataract surgery in 6 of 18 eyes, after trabeculectomy or glaucoma implant surgery in 4 eyes, after trauma in 3 eyes, after intravitreal triamcinolone injection in 1 eye, and after endogenous endophthalmitis in 4 eyes. The culture results were similar between gram positive and gram negative organisms. Final vision was 0.1 or better in 6 of the 18 eyes. Final visual acuities showed statistically significant correlation with causative organisms (p=0.018). CONCLUSIONS: For effective management of bacterial endophthalmitis and prediction of prognosis, we recommend thorough bacterial culture. Also, further investigation with a large population is needed.

PURPOSE: To assess the diagnostic efficacy of macular and peripapillary retinal thickness measurements for the staging of diabetic retinopathy (DR) and the prediction of disease progression. METHODS: In this prospective study, 149 diabetic patients (149 eyes) and 50 non-diabetic control subjects were included. Baseline optical coherence tomography was employed to measure retinal thickness in the macula (horizontal, vertical, and central) and the peripapillary zone (superior, inferior, nasal, and concentric to the optic disc). Seven baseline parameters were correlated with the DR stages identified by fluorescein angiography. Baseline retinal thickness was compared between groups of patients requiring panretinal photocoagulation (PRP) within 6 months (PRP group) and patients not requiring PRP (No-PRP group). RESULTS: Macular and peripapillary retinal thicknesses in diabetic subjects were significantly greater than that in normal controls (p<0.05). All retinal thickness parameters, and particularly peripapillary circular scans, tended to increase with increasing DR severity (p<0.05). The baseline thicknesses of the peripapillary circular scans were greater in the PRP group than in the no-PRP group (p<0.05). CONCLUSIONS: Peripapillary retinal thickness may prove to be a useful criterion for DR severity and may also serve as an indicator of disease progression.

PURPOSE: To evaluate the clinical results of deep lamellar endothelial keratoplasty (DLEK) surgery in patients with bullous keratopathy. METHODS: Seven eyes of 7 patients diagnosed with bullous keratopathy were evaluated for pre- and postoperative visual acuity, refractive error, astigmatism, and corneal topographic results. Specular microscopy and corneal pachymetry was performed in order to evaluate the corneal endothelial cell status. Postoperative complications such as graft rejection, infection, glaucoma, and graft dislocation were also evaluated. RESULTS: Preoperative visual acuity improved from 0.006 (CF ~ 0.02) to 0.4 (0.1 ~ 0.5) at an average of 1.2+/-0.18 years of follow-up. Manifest refraction, topographic astigmatism, corneal endothelial cell density, and central corneal thickness at the final visit were 1.21+/-0.73D, 2.1+/-0.70D, 1304+/-682 cells/mm2, and 504+/-128 micrometer respectively. Two eyes (28.6%) developed graft rejection, one of which recovered after intensive steroid treatment. However, one patient (14.3%) underwent penetrating keratoplasty due to graft failure at 6 months postoperatively. Seven of 7 eyes were noted to have graft dislocation, all of which were repositioned and attached after air injection or suture. CONCLUSIONS: DLEK surgery is an effective alternative to conventional penetrating keratoplasty for bullous keratopathy patients because of fast visual recovery and low incidence of postoperative astigmatism.

To describe the clinical and optical coherence tomography (OCT) features of a macular hole (MH) or its precursor lesion in patients treated with systemic antiestrogen agents. We reviewed the medical history of the patient, ophthalmic examination, and both fundus and OCT findings. Three female patients receiving antiestrogen therapy sought treatment for visual disturbance. All of the patients showed foveal cystic changes with outer retinal defect upon OCT. Visual improvement was achieved through surgery for the treatment of MH in two patients. Antiestrogen therapy may result in MH or its precursor lesion, in addition to perifoveal refractile deposits. OCT examination would be helpful for early detection in such cases.

In amebic liver abscess, communication between liver abscess and intrahepatic bile ducts is an uncommon cause of bile leak. This condition can be treated surgically or endoscopically. However, these treatment modalities are related with high morbidity and mortality. A 49-year-old man was diagnosed with amebic liver abscess. Percutaneous drainage was performed due to poor medical response and for the purpose of preventing abscess rupture. Liver abscess-biliary communication was found at follow-up imaging study. He was treated successfully with medical therapy and supportive care without further interventions.

Liposuction is one of the most frequently performed cosmetic surgeries worldwide for reshaping the body contour. Although liposuction is minimally invasive and relatively safe, it is a surgical procedure, and it carries the risk of major and minor complications. These complications vary from postoperative nausea to life-threatening events. Common complications include infection, abdominal wall injury, bowel herniation, bleeding, haematoma, seroma, and lymphoedema. Life-threatening complications such as necrotizing fasciitis, deep vein thrombosis, and pulmonary embolism have also been reported. In this paper, we provide a brief introduction to liposuction with the related anatomy and present computed tomography and ultrasonography findings of a wide spectrum of postoperative complications associated with liposuction.

The incidence of adverse toxic reactions to immunotherapy using immune checkpoint inhibitors is 2-10% in the respiratory system and 3.9% to 12% in the neurologic system. The severity of adverse effects increases when combined immunotherapeutic agents are administered.Current Concepts: In cases of high-grade toxicity, it is important to discontinue immunotherapy immediately. In cases of grade 3 to 4 toxicity, immunosuppressive corticosteroid therapy is the first-line treatment. Short-term steroid treatment does not affect anti-tumor efficacy. It is thus necessary to use steroids for an appropriate period then carefully taper the steroid dose to prevent recurrence. If no improvement is achieved within 48-72 hours after the administration of steroids, it is essential to initiate multidisciplinary treatment involving related departments and add immunosuppressive drugs. If the patient is administrated immunotherapy again, it may be necessary to permanently discontinue the immunotherapy depending on the toxicity grade that first occurred.Discussion and Conclusion: The primary goals for effective management of immunotherapy-related adverse events are early recognition of symptoms and immediate treatment.

PURPOSE: To show Humphrey automated kinetic perimetry can be substituted for Goldmann perimetry, which has been used in the field of disability evaluation field, the differences of normal visual fields between two perimetries were evaluated. METHODS: Goldmann and Humphrey automated kinetic perimetries were performed simultaneously in 70 eyes of 35 normal healthy Koreans who had no specific ophthalmologic disease at 12 meridians; 0degrees, 30degrees, 60degrees, 90degrees, 120degrees, 150degrees, 180degrees, 210degrees, 240degrees, 270degrees, 300degrees, and 330degrees. The mean values of field in each case were compared. In addition, the corrected values were obtained through the calculation of the difference in the two maximal fields. RESULTS: The visual fields of Humphrey and Goldmann kinetic perimetries showed a similar oval shape, but the fields of Goldmann were statistically significantly wider than the Humphrey fields. As the values of Humphrey were compared with the original data of Goldmann, all values of the visual field were narrow. CONCLUSIONS: The visual fields by Humphrey automated kinetic perimetry were smaller than those by Goldmann perimetry. Therefore, if Humphrey kinetic perimetry is used for the evaluation of visual disability, the visual field should be evaluated after the correction.

PURPOSE: To evaluate the short-term efficacy and safety of intravitreal bevacizumab injection (IVBI) in patients with retinal angiomatous proliferation (RAP). METHODS: Seven eyes of 5 patients with RAP were included in this study. All of the eyes evidenced stage 2 RAP lesions, except for one eye with a stage 3 lesion. IVBI (1.25 mg/0.05 cc) were conducted at 4 or 6-week intervals. Complete ocular examinations, angiographic results and optical coherence tomographic findings before and after the IVBI were analyzed at baseline and upon the follow-up visits. RESULTS: Seven eyes were studied in 5 patients who had undergone IVBI. Partial (3 eyes) or complete (4 eyes) regression of RAP was noted after IVBI in all of the studied eyes. Visual acuity improved in 5 of the eyes, and was stable in 2 of the eyes. One eye evidenced severe intraocular inflammation after IVBI and a subsequent development of new RAP, which was controlled with vitrectomy and repeat IVBI. CONCLUSIONS: This treatment was effective over 6 months, stabilizing or improving visual acuity and reducing angiographic leakage. These short-term results suggest that IVBI may constitute a promising therapeutic option, particularly in the early stages of RAP.

BACKGROUND: Colon cancer affects largely elderly populations. Elderly patients treated with adjuvant chemotherapy is lower than younger patients in colon cancer. We aim to evaluate the survival and prognostic factors in accordance with adjuvant chemotherapy in elderly colon cancer patients undergoing curative resection. METHODS: We retrospectively reviewed 86 patients 70 years of age or older with stage II, III colon cancer who were underwent surgical resection between 2005 and 2013 at single-center. We examined demographic factors, comorbidities at the time of diagnosis, factors associated with colon cancer, and factors associated with treatment, and analyzed associations survival and these factors divided into adjuvant chemotherapy group (chemotherapy group) and the conservative treatment group (observation group). RESULTS: Among 86 patients 70 years of age or older, 58 patients (67.4%) administered adjuvant chemotherapy and 28 patients (32%) underwent conservative treatment. There are significant differences in respect to the age of 75 in order to select conservative treatment or adjuvant chemotherapy for patients with surgery (p=0.008). There was no significant difference of median overall survival between both groups (chemotherapy group versus observation group: 20 months vs. 24 months, p=0.000). Poor ECOG PS score was independent prognostic factor for overall survival (95% confidential interval 0.016-0.205; hazard ratio, 0.58; p<0.001). CONCLUSION: Adjuvant chemotherapy did not affect the overall survival in stage II, III elderly colon cancer after surgical resection. There was the tendency to determine whether undergoing adjuvant chemotherapy according to chronologic age. It is thought to be necessary to perform a comprehensive geriatric assessment for decision of adjuvant chemotherapy in elderly patients.
