PURPOSE: To investigate the vitreous proteomic profiles of macular hole (MH) patients compared to donor eyes and epiretinal membrane (ERM) patients. METHODS: Ten donor eyes, 25 MH patients (15 MH without posterior vitreous detachment (PVD) and 10 MH with PVD), 10 ERM patients and 4 patients with vitreomacular traction syndrome (VMTS) were enrolled in the present study. The undiluted vitreous samples were obtained from all eyes. Proteins were identified using the micro-RPLC/MS/MS technique and using mass spectrometric data analysis from the IPI database. Proteins were searched for the function, subcellular location and tissue specificity using the Uniprot database. RESULTS: The mean vitreous protein concentrations were the highest (p < 0.01) in MH patients without PVD. There were no qualitative changes according to the age of donor eyes. However, the authors newly-identified 12 proteins (i.e. vasorin) in donor eyes. Ten out of 136 proteins (7.3%) (i.e. retinoschisin) were exclusively detected in the MH samples. S100A8 was exclusively detected in eyes without PVD, whereas CD59 was exclusively detected in eyes with PVD. CONCLUSIONS: The results suggest there is a small difference in the vitreous proteomic profiles in MH patients compared to donor eyes or ERM patients, and that the expression of vitreous proteins is closely associated with the presence of PVD.

PURPOSE: To evaluate treatment outcomes and prognostic factors in non-small cell lung cancer (NSCLC) patients treated with concurrent chemoradiation. MATERIALS AND METHODS: From January 2005 to June 2009, 51 patients were treated with concurrent chemoradiation for 3 different aims: locally advanced stage III, locally recurrent disease, and postoperative gross residual NSCLC. Median age was 63 years. Distribution of stages by the 6th edition of American Joint Committee on Cancer (AJCC) was as follows: IIIA (37.3%), IIIB (56.9%). Chemotherapy was administered every week concurrently with radiation using one of the following regimens: paclitaxel (60 mg/m2), docetaxel+cisplatin (20 mg/m2+20 mg/m2), cisplatin (30 mg/m2). Total radiation dose was 16-66.4 Gy (median, 59.4 Gy). RESULTS: Median follow-up duration was 40.8 months. The overall response rate was 84.3% with 23 complete responses. The median survival duration for the overall patient group was 17.6 months. The 3-year survival rate was 17.8%. A total of 21 patients had recurrent disease at the following sites: loco-regional sites (23.6%), distant organs (27.5%). In the multivariate analysis of the overall patient group, a clinical tumor response (p=0.002) was the only significant prognostic factor for overall survival (OS). In the multivariate analysis of the definitive chemoradiation arm, the use of consolidation chemotherapy (p=0.022), biologically equivalent dose (BED)10 (p=0.007), and a clinical tumor response (p=0.030) were the significant prognostic factors for OS.The median survival duration of the locally recurrent group and the postoperative gross residual group were 26.4 and 23.9 months, respectively. CONCLUSION: Our study demonstrated that clinical tumor response was significantly associated with OS in the overall patient group. Further investigations regarding the optimal radiation dose in the definitive chemoradiation and the optimal treatment scheme in locally recurrent NSCLC would be required.

PURPOSE: To evaluate the incidence and clinical features of age-related macular degeneration (AMD) in Korea. METHODS: Web-based (www.armd-nova.or.kr) registration was conducted for AMD patients aged 50 or more who were newly diagnosed by retinal specialists in Korea from August 20, 2005 to August 20, 2006. Patient data including ophthalmologic examination, fundus photography, fluorescein angiogram and/or indocyanin green angiogram (ICG), past medical history, behavioral habit, combined systemic diseases were up-loaded. RESULTS: Among finally enrolled 1,141 newly diagnosed AMD patients, 690 patients (60.5%) were male and 451 patients (39.5%) were female. The average age of AMD patients was 69.7+/-8.0. Early AMD was observed in 190 patients and 951 patients had late AMD. Classic choroidal neovascular membrane (CNVM) was observed in 18.6% of exudative AMD patients and 63.4 % had occult CNVM. Subfoveal CNVM was observed in 80.4% of the patients with CNVM. Among the 580 exudative AMD eyes that performed indocyanin green angiography (ICG), 184 eyes (31.7%) had polypoidal choroidal vasculopathy (PCV) and 36 eyes (6.2%) showed retinal angiomatous proliferation (RAP). Age, male gender, smoking, diabetes and hypertension significantly increased the risk of the AMD among Koreans. CONCLUSIONS: Because of the low rate of participation by retinal specialists, definite incidence of AMD was not obtainable. However, the estimated 1-year AMD incidence in the Pusan area of Korea is at least 0.4%. In contrast to Western people, 31.7% of exudative AMD cases were revealed to be PCV and 6.2% were revealed to be RAP. This discrepancy between ethnic groups should be considered in the diagnosis and treatment modality selection of Korean AMD patients.

Tuberculous uveitis is a rare manifestation of tuberculosis infection. Although early diagnosis is important to saving the sight of patients, it is difficult. In dialysis patient, the diagnosis of tuberculosis is often delayed because of non-specific symptoms and extrapulmonary involvements. We report a case involving a 37-year-old man receiving hemodialysis who was presented with persistent fever and left- sided blurred vision. At ophthalmic examination, active papillitis, vitritis, and peripapillary retinal detachment were observed. Neck computed tomography showed multiple necrotic lymphadenopathies (LAPs) in right lateral neck, which was proven as tuberculous lymphadenitis on histological examination. After anti-tuberculosis therapy, fever was subsided and LAPs were improved. Visual acuity was also improved.

PURPOSE: To prospectively investigate the change of clinical manifestations after 1 year of administration of anthocyanoside (Tagen-F(R)) to patients with NPDR-associated macular edema. METHODS: One hundred seventy-five eyes in 88 patients were enrolled in this study, at 5 centers, from March, 2005 to October, 2005. Patients took 3 capsules of Vaccinium myrtillus extract (170 mg/capsule, Tagen-F(R), Kukje pharmaceutical) per day. The primary endpoints were corrected visual acuity and contrast sensitivity which were checked at 2 months following the beginning of treatment [East 1]. The secondary endpoints were the number of hard exudates, microaneurysms, leaking points and the changes of foveal thickness. These were examined at the beginning of, 6 months after, and 12 months after treatment. RESULTS: Corrected visual acuity showed no significant changes during 12 months. Contrast sensitivity improved gradually, especially in 12, 16 cycles per degree [East 2]. There was no statistically significant changes in the numbers of hard exudates, microaneurysms, and leaking points. Foveal thickness measured by OCT was maintained and there was no aggravation of macular edema. CONCLUSIONS: There was marked improvement of contrast sensitivity in patients with NPDR after 1 year of administration of anthocyanoside (Tagen-F(R)), and it might contribute to the quality of vision and the satisfaction of patients. Visual acuity and macular edema were maintained without aggravation.

PURPOSE: To investigate the changes of aqueous vascular endothelial growth factor (VEGF) and interleukin (IL)-6 in patients with acute macular edema secondary to recent-onset branch retinal vein occlusion (BRVO) after a single intravitreal injection of triamcinolone acetonide (IVTA) METHODS: Aqueous and plasma levels of VEGF and IL-6 were measured by ELISA in ten controls and thirty patients at the time of IVTA and 3 months afterward. We compared the aqueous levels of VEGF and IL-6 and the clinical course between responders and non-responders. RESULTS: The aqueous levels of VEGF and IL-6 were significantly higher in non-responders than in responders at baseline measurements (495+/-259 pg/ml vs. 223+/-110 pg/ml, P<.001; 36+/-32 pg/ml vs. 16+/-19 pg/ml, P=.037, respectively). The aqueous levels of VEGF were still higher in non-responders (303+/-75 pg/ml) 3 months after IVTA, while the aqueous levels of VEGF in responders returned to normal (77+/-23 pg/ml, P<.001). The aqueous levels of IL-6 normalized in all patients 3 months after IVTA. In non-responders, central foveal thickness was significantly higher, and foveal ischemia and a wide non-perfused area were more common. CONCLUSIONS: Non-IL6-dependent VEGF may contribute to persistent or recurrent ischemic macular edema associated with BRVO after IVTA.

PURPOSE: To compare the clinical outcomes between scleral buckling and vitrectomy in the primary management of pseudophakic retinal detachment with an intact posterior capsule. METHODS: The medical records of 63 eyes that underwent scleral buckling (36 eyes) or vitrectomy (27 eyes) as a primary operation of uncomplicated pseudophakic retinal detachment with intact posterior capsules with a follow-up of more than one year were retrospectively reviewed from 2000 to 2005. We compared the clinical outcomes using anatomical and functional success rates at postoperative one year. Anatomical success was defined by a reattachment rate and functional success was measured by a change of more than 0.3 logMAR. RESULTS: Anatomical success rates were 86% in the scleral buckling and 82% in the vitrectomy, respectively (p=0.837). Functional success rates were 81% in the scleral buckling and 70% in the vitrectomy, respectively (p=0.065). There were no significant differences of anatomical and functional success rates according to each surgical procedure. CONCLUSIONS: Either scleral buckling or vitrectomy may be chosen as a primary operation in the management of pseudophakic retinal detachment with intact posterior capsule.

We report one family with bilateral renal hypoplasia and ocular coloboma in two consecutive generations. Ophthalmological examination revealed optic disc coloboma and decreased visual acuity. Fragments spanning exon 1-12 of the PAX2 gene were amplified from genomic DNA using PCR primers. The PCR products were purified and directly sequenced. No definite mutation was detected in the PAX2 genes in these patients, but two coding region single nucleotide polymorphisms were identified. This result suggests that the optic disc coloboma with bilateral renal hypoplasia might be genetically heterogenous or other genes could be responsible.
