This cross-sectional study was done to identify and determine the socio-demographic and health-related factors associated with diabetic retinopathy and nephropathy screening in Korea. Participants included 2,660 adults, aged 40 or older, with diabetes. Of the 2,660 adults, 998 (37%) and 1,226 (46.1%) had received a diabetic retinopathy and a nephropathy screening within one year, respectively. Regarding retinopathy, subjects older than 65, living in urban areas, with high educational levels, and with self-reported "unhealthy" status were likely to receive annual screening. Subjects living in urban areas, with higher educational levels, with self-reported "fair" or "unhealthy" status, and with 1 to 2 co-morbidities were likely to receive annual nephropathy screening. The Korea Composite Stock Price Index (KOSPI) continued to rise until 2007 when it started to decline over the subsequent years, following the same curve as the diabetic retinopathy and nephropathy screening rates during that time. Together with the financial matter, lack of patient education proved to be a hindrance to diabetes-related screening. The relatively low screening rates in Korea compared to the Western countries are likely to be due to the difference in the health system, economic situations and national demographics.

PURPOSE: To evaluate the efficacy of intravitreal triamcinolone acetonide (IVT) for the management of postvitrectomy diabetic vitreous hemorrhage. METHODS: The authors conducted a retrospective study of patients with postvitrectomy diabetic vitreous hemorrhage who were administered 4 mg (0.1 cc) of triamcinolone acetonide ophthalmic suspension. Ocular history, adverse events, BCVA, intraocular pressure, external eye examination, slit-lamp biomicroscopy, fundus examination, B-scan ultrasonography, and fundus photography were assessed on day 1, weeks 1, 2, and 4 and months 2 and 3. RESULTS: There were 19 eyes of 18 consecutive patients with mean follow-up after IVT injection of 28 weeks. Of the 19 eyes, 17 eyes (89%) experienced clearing of vitreous hemorrhage within 1 to 5 weeks (mean, 1.7 weeks) with visible triamcinolone precipitates along with blood clot in the inferior aspect of fundus. Of these 17 eyes, 12 eyes (63%) maintained vitreous hemorrhage-free condition at last follow-up with a mean visual acuity of 20/63 (range, 20/320 20/25), whereas 5 (29%) developed recurrent vitreous hemorrhage after clearing of vitreous hemorrhage. Vitreous hemorrhage was not cleared in 2 eyes, which required surgical procedures. CONCLUSIONS: IVT injection may be beneficial for clearing recurrent postvitrectomy Diabetic Vitreous Hemorrhage.

PURPOSE: To compare the efficacy between intravitreal bevacizumab and combination treatment (bevacizumab and macular photocoagulation) for the treatment of diabetic macular edema (DME). In addtion, changes of DME type were researched using optical coherence tomography. METHODS: The present study included 90 eyes with bevacizumab injection and 38 eyes with combination treatment. Using chart records, patients were reviewed until 6 months after treatment. The present study compared changes of visual acuity (VA) and macular thickness at each follow up. DME was classified into 4 types and the morphologic pattern was compared. RESULTS: In patients with the bevacizumab injection only, VA improved from 0.29 +/- 0.18 to 0.48 +/- 0.26 at 1 month and returned to 0.32 +/- 0.20 at 6 months after treatment. In the combination treatment, VA improved from 0.32 +/- 0.22 to 0.52 +/- 0.26 at 1 month and returned to 0.36 +/- 0.18 at 6 months after treatment. There was no significant improvement of VA at the final follow-up with either treatment. There was significant decrease of macular thickness except in the mixed DME type. CONCLUSIONS: The combination treatment did not yield better VA or macular thickness reduction at 6 months than bevacizumab injection alone. By classifying and observing the change of DME type, determining the treatment objectively and predicting the effectiveness of treatment can be helpful.

PURPOSE: To evaluate the effect of different doses of intravitreal triamcinolone acetonide on diffuse diabetic macular edema. METHODS: In a retrospective study, 44 eyes with diffuse diabetic macular edema were treated with an intravitreal injection of 4 mg (n=12 eyes), 8 mg (n=17) or 25 mg (n=15) of triamcinolone acetonide (TA). Optical coherence tomography, best-corrected logMAR visual acuity and Goldmann tonometry were performed at baseline, 1 week, and 1, 3, 6, 9 and 12 months after treatment. Mean follow-up was 9.8 months (standard deviation=2.3) with a range of 5-12 months. RESULTS: The duration of intravitreal TA effects on macular thickness and visual acuity increased with increasing dosage. An observed increase in intraocular pressure induced by TA was not significantly associated with dosage. CONCLUSIONS: In patients with diffuse diabetic macular edema who receive intravitreal TA, effects may last longer after a dosage of 25 mg, than after lower doses of 8 mg or 4 mg.
