PURPOSE: The purpose of this study was to identify the degree of attaining a smoking cessation goal when an agreement on means to achieve smoking cessation among male college student smokers was established. METHOD: This study was planned as a nonequivalent control group non-synchronized design and the sample was divided into an agreement group and a comparison group by convenience sampling in a college of G city. The data was analysed with SPSS Win10.0 using a Likelihood chi2-test, Odds ratio, Paired t-test and ANCOVA. RESULT: The theory that the degree of smoking cessation will be higher in the agreement group than the Comparison group was rejected (delta = 2.567, p = .055). The theory that nicotine dependency will be lower in the agreement group than the comparison group was supported (F = 3.965, p = .049); however, the theory that the number of cigarettes smoked per day will be lower in the agreement group than the comparison group was rejected (F = 1.342, p = .252). CONCLUSION: It has been shown that an agreement on means to achieve smoking cessation goals is a key factor to success in quitting smoking.

Anthors have evaluated postoperative visual outcome and complications on 60 high myopic patients who had underwent extracapsular cataract extraction (ECCE) with or without posterior chamber intraocular lens (PC IOL) implantation, retrospectively. The average axial length of eyeballs of patients underwent only ECCE and ECCE with PC IOL were 30.7 mm and 27.04 mm, respectively. Corrected visual acuity was improved in 56 eyes (91.5%) after cataract sugery. 19 eyes (63.6%) out of 30 aphakia and 11 eyes(36.2%) out of 30 pseudophakia showed better than 20/40 and this difference was statistically significant (p< 0.05). Posterior capsular opacity and cystoid macular edema (CME) were founf in 7 eyes (23.3%) and in 2 eyes (6.6%) of 30 aphakia, while those were in 2 eyes (6.6%) and 1 eye (3.3.%) of 30 pseudophakia, respectively. However, these complications did not decrease a visual acuity and there was no retinal detachment in both aphakia and pseudophakia, with these resuls, it was founf that the clinical results of ECCE with PC IOL was more effective in visual improvement and prevention of posterior capsular opacity than only ECCE for high myopic patients.

PURPOSE: To evaluate the effectiveness of Ahmed valve implantation for refractory glaucoma following pars plana vitrectomy. METHODS: Seventeen eyes of 15 patients suffering from secondary glaucoma following pars plana vitrectomy underwent Ahmed valve implantation. All the eyes were in critical condition, and intraocular pressure could not be controlled with anti-glaucoma medications. Success was characterized by an intraocular pressure less than 22 mmHg and greater than 6 mmHg, regardless of anti-glaucoma medication usage. RESULTS: The total success rate was 83.4% at 6 months and 76.4% at the final visit. The reduction in intraocular pressure and the number of medications used postoperatively were both statistically and clinically significant (p< 0.005). Postoperative complications included: transiently increased intraocular pressure, transient hyphema, early postoperative hypotony, choroidal detachment, malposition of the valve tip, and phthisis bulbus. CONCLUSIONS: Ahmed valve implantation is a safe and effective method for refractory glaucoma following vitrectomy.

Hydroxyapatite is generally used as an orbital implant which is biocompatible. It is considered esthetically and functionally better than traditional measure. We performed hydroxyapatite implantation using autogenous temporalis muscle fascia for 4 eyes of 4 phthisis patients by truma. Hydroxyapatite implants wrapped with autogenous temporalis muscle fascia were inserted into all eyes after enucleation. Follow-up for 12-15 months [mean:13.4 months] showed less inflammatory reaction. There were has no wound dehiscence, implant protrusion and migration. MRI showed a goodfibrovascular proliferation at 4-5 months postoperatively, so we performed drilling. Temporalis muscle fascia is easily obtained and there is no esthetic problem because scar at scalp is covered by hair.

A study on objective personality characteristics of 41 central serous chorioretinopathy patients was performed to investigate the etiologic relationship of psychological behaviors about the central serous chorioretinopathy. Fourty-one healthy subjects were used as a control group. Authors used the Minnesota Multiphasic Personality Inventory (MMPI) which consisted of 4 validity scales and 10 clinical scales. Three neurotic scales of hypochondriasis, depression and hysteria in the atients group were significantly higher than in the normal control group even though the mean scores on each clinical scale were within normal ranges in both groups.

Phacoemulsification combined with pars plana vitrectomy was performed on seventeen eyes with both cataract and vitreoretinal disease. Postoperative visual acuity improved in ten of seventeen cases. There was no serious perioperative complication. In those eyes with both cataract and vitreoretinal disease, the small incision used in phacoemulsification allows better control of the anterior chamber during vitrectomy. In addition, this procedure allows endocapsular fixation of the intraocular lens.

Air-bags have received widespread support as an effective means of enhancing automotive safety, and they are becoming more common as standard automobile equipment on many cars. Although air-bag induced ocular injuries are rare, they present a serious concern because of the possibility of permanent damage or visual impairment. To date, most reports have investigated ocular injury from high velocity motor vehicle accidents and reports of ocular injury from low speed motor vehicle accidents have been rare. We describe a patient who sustained severe ocular injury, including periorbital fracture, hyphema, vitreous hemorrhage, and choroidal rupture of the macular area, due to an inflated air-bag in a low speed motor vehicle accident.

PURPOSE: To elucidate the mechanism of neoangiogenesis in human retinal pigment epithelium under oxidative stress. METHODS: Paraquat was added to cultured human retinal pigment epithelium (HRPE) for 72 hours to induce oxidative stress milieu. Expression and production of angiogenic factors, including vascular endothelial growth factor (VEGF) and pigment epithelial derived factor (PEDF), was checked by RT-PCR and Western blot, respectively. The induction of neoangiogenesis was monitored by both tube formation in ECV 304 cell and migration assay of human fetal dermal microvascular endothelial cells. RESULTS: Competitive RT-PCR showed that PEDF gene in paraquat-treated HRPE was expressed at a significantly lower level than in non-treated HRPE. However, Western blot showed a significant increase of VEGF production (p<0.05) and a decrease of PEDF production (p<0.05). Moreover, angiogenesis was dose-dependently increased when the various concentrations of paraquat were added to HRPE. CONCLUSIONS: Taken together, oxidative stress by addition of paraquat caused HRPE to produce more VEGF and less PEDF, thereby leading to neoangiogenesis, and suggesting that the neovascularization in age-related macular degeneration (AMD) is caused by destroying the balance of angiogenic factors in HRPE such as VEGF and PEDF; that is, in oxidative stressed HRPE, more VEGF is released and less PEDF, as compared to normal HRPE.

Argon laser trabeculoplasty(ALT) is commonly used in the treatment of uncontrolled open angle glaucoma. The authors retrospectively reviewed the efficacy of ALT in 52 patients(57 eyes) with primary open angle glaucoma. The mean follow-up was 28 months(range 2-48 months). The decrease in intraocular pressure 10P) was 10.1 +/- 3.5 mmHg at 1 month, 8.2 +/- 2.8 mmHg at 1 year, 6.2 +/- 5.1 mmHg at 2 years and 51% at 3 years. Failure was most common in the first 6 months after treatment(29%) and thereafter failure occurred at a rate of 5% to 15% per year. The sex and age of patients had no significant effect on success rate. The success rate was high in the patients with baseline IOP of 26 to 30 mmHg. A mild iritis in all cases, transient rise in IOP, peripheral anterior synechia and microscopic hyphema were noted as early complications of ALT.

PURPOSE: To evaluate the expression pattern of gelatinases in the human retinal pigment epithelial cell line ARPE-19 in response to oxidative stress. METHODS: ARPE-19 cells were exposed to paraquat for 72 hours. The cells were assayed for the mRNA expression of gelatinase A and gelatinase B by reverse transcriptase polymerase chain reaction (RT-PCR). The conditioned media were assayed for the production of gelatinases protein by Western blotting. Also, the inhibitory effect of the antioxidants against oxidative stress to the cells was evaluated. RESULTS: The gelatinase levels in the RPE cells increased under oxidative stress compaired with the control (p<0.05). Also, the levels decreased when the cells were incubated with the antioxidant N-acetylcysteine (NAC). CONCLUSIONS: Oxidative stress upregulates gelatinase expression in ARPE-19 cells.
