Introduction: The study has to determine whether implantation of diffractive multifocal lenses during cataract phacoemulsification causes distortion of the cognitive aspects of processing perceptual information. Material and methods: 25 patients who underwent cataract phacoemulsification with the implantation of diffractive multifocal lens Acrysof Restor SN6AD1 in both eyes (multifocal group) and 26 patients with the implantation of monofocal intraocular lens Acrysof IQ SN60WF in both eyes (monofocal group) were enrolled. All patients underwent ophthalmic examination and cognitive function-Trial Making Test (Part A and Part B) and Stroop Test (Stroop Test 1 and Stroop Test 2) tests at least 6 months after cataract surgery of the other eye. Results: Mean patient age and visual acuity with correction for near and far vision did not differ between groups.
Background and Objectives: Intraretinal cysts are common pathology observed inspectral domain optical coherence tomography (SDOCT) in patients with neovascular form of age-related macular degeneration (AMD). The aim of the study was to determine if the presence of intraretinal cysts is positively correlated with diagnosis of retinal angiomatous proliferation (RAP) in optical coherence tomography angiography (OCTA). Material and Methods: A total of 21 eyes with intraretinal cysts in SDOCT exam (Group1) and 21 eyes with subretinal fluid(Group 2) were enrolled into the study. In each eye, the presence of intraretinal neovascularization (IRN) and chorioretinal anastomosis (CRA) was evaluated in OCTA by two experienced graders. Results: IRN was observed in 20 eyes (95.2%) from Group 1 and 5 eyes (23.8%) from Group 2. Features of CRA were found in 18 eyes (80.95%) and 16 eyes (76.2%) respectively for Group 1 and 2. Patients with cysts are 50 (95% CI: 5.43–460.52) times more likely to have IRN (p< 0.001). Conclusions: The presence of intraretinal cysts on SDOCT retinal sections in eyes with neovascular AMD corresponds to the presence of IRN on OCTA examination. The results indicate that the absence of a cyst does not exclude the presence of IRN and CRA which can be identified on OCTA.
Background: Homocystinuria is an autosomal recessively inherited defect of methionine catabolism. This rare condition causes abnormal accumulation of homocysteine in the blood and urine that is not typically found in significant quantities. While elevated homocysteine levels can cause damage to multiple organ systems, they most often affect the cardiovascular, musculoskeletal, ocular, and central nervous systems. Nearly 20% of affected individuals who are untreated die from thrombotic complications before the age of 30.
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.
