PURPOSE: We report a case of post-traumatic hypotony retinopathy with cyclodialysis cleft treated by intravitreal gas injection. METHODS: A 38-year-old man presented with decreased visual acuity after blunt trauma to the left eye. Visual acuity of the left eye was 0.06 and intraocular pressure was 1 mmHg. No external wound was found. The anterior chamber showed a microscopic hyphema and, upon funduscopic examination, mild macular edema and striae were seen. The cyclodialysis was identified using gonioscopy. We treated the patient with intravitreal gas (perfluoropropane, C3F8) injection under topical anesthesia and tracked the outcome of this treatment. RESULTS: On the first postoperative day, intraocular pressure fell to the normal range. After 7 days the visual acuity improved to 1.0. During a follow-up period of 10 months, intraocular pressure and visual acuity remained in their normal range. CONCLUSIONS: Intravitreal gas injection offers a safe and effective method of treating hypotony retinopathy with cyclodialysis cleft.

PURPOSE: Although influenza is one of the most important causes of acute respiratory tract infections in children, effective antiviral therapies are not common and there are only a few clinical studies on treatment of influenza in children. We evaluated the efficacy of oseltamivir in the treatment of naturally aquired influenza in children during the first half of 2004 in Busan. METHODS: From January 2004 to June 2004, throat swabs and nasal washes were performed and cultured for the isolation of influenza virus and tested by rapid antigen detection test (QuickVue influenza test) in children with suspected influenza infections. The children who responded positively to the QuickVue influenza test, we divided into two groups: an oseltamivir treatment group and a control group. We compared their clinical symptoms (including fever duration) and diagnosis. The medical records of patients with influenza virus infection were reviewed retrospectively. RESULTS: A total of 621 individuals were suspected of influenza infection. Influenza viruses were isolated in 79 (17.2 percent) out of 621 patients examined. QuickVue influenza tests were positive in 181 cases. The treatment group (83 individuals) received oseltamivir twice daily for 5 days, and the control group (99 individuals) were administered only symptom relief medicine. There was no differences between the two groups in clinical diagnosis and symptoms. Oseltamivir treatment reduced the fever duration and other respiratory symptoms. There were no adverse events associated with oseltamivir treatment. CONCLUSION: Our data suggest that oral oseltamivir treatment reduces the fever duration and other respiratory symptoms of acute influenza without side effects in children.

PURPOSE: To report a case of endogenous endophthalmitis due to Aeromonas hydrophila in a patient with distal common bile duct carcinoma and biliary sepsis. METHODS: A 72-year-old woman with distal common bile duct carcinoma, obstructive jaundice, diabetes mellitus, and hypertension had a 1-day history of blurred vision, redness, and eye discharges in the right eye. An ophthalmic examination showed no light perception vision, increased intraocular pressure, severe corneal edema, severe anterior chamber reaction, exudative membranes on the anterior lens surface, and severe vitreal reaction. There was no ocular history of trauma, infection, or surgery in either eye. RESULTS: Under the impression of endogenous bacterial endophthalmitis, immediate intraocular cultures and intravitreal antibiotic injections were performed, but the anterior chamber reaction, and the ultrasonogram findings were deteriorated. Evisceration was undertakened because of extrusion of the intraocular contents, and Aeromonas hydrophila was isolated by intraocular culture. CONCLUSIONS: Endogenous endophthalmitis due to Aeromonas hydrophila is rare, but has a rapid clinical course and a poor prognosis, despite of prompt diagnosis and management.

Telecanthus in congenital blepharophimosis has traditionally been repaired with conventional methods such as medial canthal tendon tucking and transnasal wiring.We report 2 cases of patients with telecanthus who underwent repair with titanium miniplate. After the anterior limb of medial canthal tendon was dissected, its insertion site was drilled and a titanium miniplate was fixed with screws.The dissected medial canthal tendon was fixed with 4-0 mersilene to a miniplate hole.After the surgery, we obtained a mean decrease of 11 mmin intermedial canthal distance and no complications except scar in incision site. We believe that this procedure has advantages such as short operation time, precise placement of the medial canthal tendon.For these reasons, it seems to be an excellent alternative to transnasal wiring, but considers this operation because of scar in incision site.

Purpose: To confirm that the phaco chop method using an illuminated chopper (iChopper; Oculight, Seongnam, Korea) can reduce cataract surgery complications, and that even beginners can safely and effectively perform phaco chop. Methods: We retrospectively analyzed the medical records of the first 30 phaco chop cases using illuminated chopper of four cataract surgeons. Four ophthalmologists had a variety of empirical backgrounds, from those who have experienced more than 10,000 cataract surgery, to beginners who have experienced 20 cataract surgery. Results: Of the total 120 eyes, two eyes (1.67%) had posterior capsule rupture. The chopping method was changed from phaco chop to stop and chop in three eyes (2.5%) including one eye with brown cataract with pseudoexofoliation syndrome and two eyes with nuclear opacity grade ≥5. Conclusions The rates of posterior capsule rupture of phaco chop using an illuminated chopper were very low in four surgeons with various experiences and who became proficient shortly in phaco chop.

Purpose: To minimize ultrasound power use and surgical phaco time in illuminated chop cataract surgery. Methods: The charts of patients who underwent senile cataract surgery by a single surgeon were reviewed retrospectively. A conventional intracameral endoilluminator was used in a Stop & Chop group (n = 45), while an illuminated chopper was used in an illuminated chop (I-Chop) group (n = 71). EFX, a unitless value that roughly correlates with ultrasound energy during phacoemulsification, surgical phaco time, and changes in endothelial cell count were compared between the two groups and the ratio of zero phacoemulsification in the I-Chop group was evaluated. Results: EFX of the Stop & Chop and I-Chop groups was 18.08 ± 16.15 and 0.82 ± 3.53, respectively (p = 0.001), while the surgical phaco time was 185.08 ± 41.42 and 162.04 ± 49.65 seconds (p = 0.01). However, the endothelial loss did not differ in the two groups (7.03 ± 7.89 vs. 7.13 ± 9.47%, p = 0.76). In the I-Chop group, 56 (86%) eyes had zero phaco energy and patients with EFX >1 (n = 6) had more severe nuclear sclerosis grading (2.90 ± 0.71 vs. 4.5 ± 1.0; p = 0.001). Conclusions The I-Chop group had lower EFX and shorter surgical phaco time than the Stop & Chop group. Illuminated chop using an illuminated chopper is one way to attain minimal phacoemulsification.

Purpose: This study analyzed the effects of non-damaging retinal laser therapy (NRT) in patients with chronic central serous chorioretinopathy. Methods: A retrospective study was conducted on patients with chronic central serous chorioretinopathy who were undergoing follow-up with NRT from November 2016 to February 2018. NRT was performed in patients who underwent intravitreal anti-vascular endothelial growth factor (anti-VEGF) injection at least two times with no improvement in visual acuity and a reduced amount of subretinal fluid. Before and after treatment, logMAR best-corrected visual acuity (BCVA) evaluation and subretinal fluid (SRF) according to thickness measurements of the macula determined from optical coherence tomography imagery were performed over a period of at least 6 months. Results: Eighteen eyes of 18 patients (11 male and 7 female) with chronic central serous retinopathy were treated with NRT. The mean age of patients was 54.6 ± 13.19 years old and the mean duration of follow-up was 9.75 ± 3.20 months. The central macular thickness decreased from 375 to 246 nm (p < 0.001) and BCVA improved from 0.48 to 0.40 (p = 0.028). SRF completely resolved in 55.56% of the patients after NRT. Conclusions In patients with chronic central serous chorioretinopathy, which did not improve even after intravitreal anti-VEGF injection, NRT is a relatively safe and effective treatment.

PURPOSE: To evaluate the concentrations of commercially available ofloxacin 0.3%, levofloxacin 0.5%, and ciprofloxacin 0.3% topical ophthalmic solutions in human aqueous humor. METHODS: Patients scheduled to undergo phacoemulsification and posterior chamber lens insertion for treatment of cataract were enrolled in this prospective study. After informed consent was obtained, patients were randomized to receive 1 drop of ofloxacin 0.3%, levofloxacin 0.5%, or ciprofloxacin 0.3% topical ophthalmic solution 5 times at 1-hour intervals from 6pm one day before surgery and 3 further times at 5-min intervals immediately before surgery. After aspirating approximately 0.1 mL of aqueous fluid by paracentesis, surgery was commenced. We recorded the interval between the last drop and paracentesis. Specimens were stored at -70 degrees C until assayed by high-performance liquid chromatography. RESULTS: Thirty-four patients were enrolled. 14 male and 19 patients female. The mean age was 59.4 years. The mean concentrations of levofloxacin, ofloxacin and ciprofloxacin in aqueous humor were 577.8 ng/ml, 279.6 ng/ml and 53.0 ng/ml, respectively. The differences of concentration among the three groups were statistically significant. CONCLUSIONS: The concentration of levofloxacin 0.5% solution was highest, followed in order by ofloxacin 0.3% and ciprofloxacin 0.3%.

PURPOSE: We compared the posterior capsule rupture (PCR) rate between microscope versus intracameral illumination in phacoemulsification surgery performed by novice ophthalmologists. METHODS: We conducted a retrospective chart review of 300 eyes of 211 patients who underwent phacoemulsification by novice ophthalmologists from March 2012 to October 2017. Novice ophthalmologists (n = 6) were divided into those using microscope illumination (n = 4) and intracameral illumination users (n = 2). The first 50 cataract surgery cases of each novice ophthalmologist were reviewed. The results using a phacoemulsification machine and microscopy were the same. The intraoperative complications and learning curve in each case were evaluated. RESULTS: Phacoemulsifications performed by novice ophthalmologists showed a statistically significant difference in PCR rate between the microscope illumination (19.0%, 38/200) and intracameral illumination (4.0%, 4/100) groups (p = 0.001). The incidence of PCR was reduced to 22%, 18%, 16%, 12%, and 8% per 10 cases in the microscope group, while it was 15% in the first 10 cases and 0% in 50 cases thereafter in the intracameral illumination group. CONCLUSIONS: Novice surgeons had a lower PCR rate during cataract surgery using intracameral illumination than using microscope illumination. Both groups showed a tendency for the PCR to decrease with increasing surgical cases, but the intracameral illumination group showed a shorter learning curve.

Post-menopausal osteoporosis (PMO) is a major global human health concern. Owing to the need for therapeutic drugs without side effects, natural extracts containing various polyphenolic compounds that may exert estrogenic effects have been studied in depth. Rhus verniciflua Stokes (RVS), which has been used as a traditional herbal medicine for centuries in Korea, was recently revealed to exert estrogenic effects attributable to its bioactive ingredients sulfuretin and butein, which have strong estrogen receptor–binding affinities. In this study, the protective potential of RVS in PMO was evaluated by using an experimental animal model of PMO, which was established by ovariectomy (OVX) of female Sprague Dawley rats. The oral administration of RVS at 20 mg/kg or 100 mg/kg for 8 weeks markedly protected against OVX-induced atrophy of the uterine tube and reversed the elevation in the ratio of serum receptor activator of nuclear factor-κB ligand to osteoprotegerin, which is a marker of disease severity. In addition, RVS inhibited OVX-induced tibia bone loss, activated osteogenic activity, and suppressed osteoclastic activity in the tibial epiphyseal plate, a region of bone remodeling. Collectively, these factors indicated that the oral intake of RVS might be beneficial for the prevention of PMO.
