This study showed the barrier effect of the edge design of the C-flex IOL and the efficacy of the enhanced edge in preventing LEC migration at the optic-haptic junction. The enhanced edge was as effective as a sharp square edge in restricting the LEC migration.
Both intraocular lens showed a good capsular bag performance and a relatively low posterior capsule opacification development within the first 2 years after surgery.
Aims To determine disc haemorrhage (DH) prevalence in an elderly UK population-the Bridlington Eye Assessment Project (BEAP). Methods Thirty-degree fundus photographs (3549 participants ≥65 years) were graded for DH/macula changes. Glaucoma evaluation included Goldmann tonometry, 26-point suprathreshold visual-fields and mydriatic slit-lamp assessment for glaucomatous optic neuropathy. Results In all, 3548 participants with photographs in at least one eye. DHs were present in 53 subjects (1.49%), increasing from 1.17% (65-to 69-year age group) to 2.19% (80-to 84-year age group), p = 0.06. DH was found in 9/96 (9.38%) right eyes (RE) with open-angle glaucoma (OAG). Two of twelve RE (16.67%) with normal-tension glaucoma (NTG) had DH. Prevalence in eyes without glaucoma was lower (32/3452, [0.93%]). Reticular pseudodrusen (RPD) occurred in 170/3212 (5.29%) subjects without DH, and 8/131 subjects (6.11%) with OAG. Twenty eyes had NTG, two of whom had RPD (10%) (p = 0.264). Within a logistic regression model, DH was associated with glaucoma (OR 10.2, 95% CI 5.32-19.72) and increasing age (OR 1.05, 95% CI 1.00-1.10, p = 0.03). DH was associated with RPD (p = 0.05) with univariate analysis but this was not statistically significant in the final adjusted model. There was no significant association with gender, diabetes mellitus (DM), hypertension treatment or Age-related Macular Degeneration (AMD) grade. Conclusion DH prevalence is 1.5% in those over 65 years old and significantly associated with glaucoma and increasing age. There appears to be increased RPD prevalence in eyes with DH and NTG with age acting as a confounding factor. Larger studies are required to fully assess the relationship and investigate a possible shared aetiology of choroidal ischaemia.
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.
