Intravitreal bevacizumab before PRP can be an effective adjunctive treatment to PRP in the treatment of high-risk proliferative diabetic retinopathy, especially if there is not CSME.
To examine the association of diabetes mellitus and early age-related macular degeneration (AMD) in Korean adults 50 years and older. Methods: This study included 3008 participants aged 50 to 87 years. Early AMD was assessed from retinal photographs based on a modified Wisconsin AMD grading system. Diabetes mellitus was defined as a fasting glucose level of 126 mg/dL or greater or the use of antidiabetic medications. Logistic regression was used to examine the association between diabetes mellitus and early AMD. Results: There were 88 subjects with early AMD and 315 subjects with diabetes mellitus. After adjusting for age, sex, current smoking, obesity, and hypertension, significant association was found between diabetes mellitus and early AMD. Subjects with diabetes mellitus were more likely to have early AMD (odds ratio, 1.87; 95% confidence interval, 1.07-3.28) than were those without diabetes mellitus. Conclusion: There is a relationship between diabetes mellitus and early AMD in Korean adults 50 years and older. The underlying biological processes remain to be determined.
PDT for CSC was effective with regard to anatomic and functional outcomes. However, visual improvement may be limited in patients with prolonged symptom duration, baseline confluent RPE atrophy, foveal OS-IS disintegrity, or progression of RPE atrophy after PDT and the risk of PDT-induced foveal injury should be considered.
PurposeTo compare the short term effects of topical 0.05% cyclosporine (CsA) and a mixture of 0.08% chondroitin sulfate and 0.06% sodium hyaluronate (CS-HA) on dry eye ocular surfaces.Methods36 patients with moderate to severe dry eye (5 mm/5 min or less with Schirmer's test or tear break up time (BUT) less than 6 seconds), were treated with topical application of CS-HA on one eye and CsA on the other 4 times a day for 6-8 weeks. BUT, Schirmer's test without anesthesia, and conjunctival impression cytology (CIC; goblet cell density, nucleus to cytoplasmic ratio, and epithelial cell morphology) were evaluated and compared between eyes before and after treatment (repeated measurement of ANOVA).ResultsAfter treatment, BUT and tear wettings were significantly prolonged in each group. Topical CsA treated eyes had greater increase in BUT (p=0.026); there was no significant difference in tear wetting (p=0.132). While the 3 parameters of CIC improved in both groups, goblet cell density was significantly higher in eyes treated with CsA (p=0.033).ConclusionsWhile both CS-HA and 0.05% CsA eyedrops improve ocular surfaces, topical CsA may have a better effect on enhancing tear film stability and goblet cell density.
There has been no report about hereditary and clinical features of retinitis pigmentosa (RP) in Koreans. To evaluate these, data were collected from 365 RP patients including age, gender, visual acuity (VA), spherical equivalent (SE) of refractive errors, funduscopic findings, color vision test, visual field score (VFS) obtained from Goldmann perimetry, and the inheritance patterns from pedigrees. Simplex RP was the most common inheritance pattern (61.9%); followed by autosomal recessive RP (17.3%), autosomal dominant RP (12.1%) and X-linked recessive RP (8.8%). Myopia was the most common refractive errors (77.5%) including 16.1% of high myopia. The most common cataract type was posterior subcapsular cataract (25.8%). Observed retinal findings included changes of retinal pigment epithelium (88.8%), bony spicule-like pigmentation (79.7%), attenuation of retinal vessel (76.2%), waxy disc pallor (12.6%), golden ring around optic disc (2.2%), epiretinal membrane (0.8%) and cystoid macular edema (0.5%). Corrected VA and refractive errors did not show any significant difference between the inheritance patterns. VFS was significantly worse in autosomal recessive RP than in autosomal dominant RP. Color vision defect was noted in 66.1% on Hardy-Rand-Rittlers color vision test. In conclusion, Korean RP patients have the indigenous hereditary and clinical features as well as the ordinary ones.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
