AIM To report the visual and clinical outcomes of a pilot study of subthreshold diode micropulse (SDM) laser photocoagulation for clinically significant diabetic macular oedema (CSMO). METHODS The results of infrared (810 nm) SDM laser photocoagulation for CSMO were retrospectively reviewed in 95 eyes of 69 consecutive patients with mild to moderate(More)
Elevated intraocular pressure (IOP) is a major risk factor for glaucoma and is influenced by genetic and environmental factors. Recent genome-wide association studies (GWAS) reported associations with IOP at TMCO1 and GAS7, and with primary open-angle glaucoma (POAG) at CDKN2B-AS1, CAV1/CAV2, and SIX1/SIX6. To identify novel genetic variants and replicate(More)
PURPOSE To examine the importance of genetic factors in age-related macular degeneration by using a twin study to compare the concordance of age-related macular degeneration in monozygotic twin pairs and their spouses. METHODS This was a prospective study that included 50 twin pairs and 47 spouses. Zygosity was determined by genetic laboratory testing.(More)
Optic nerve degeneration caused by glaucoma is a leading cause of blindness worldwide. Patients affected by the normal-pressure form of glaucoma are more likely to harbor risk alleles for glaucoma-related optic nerve disease. We have performed a meta-analysis of two independent genome-wide association studies for primary open angle glaucoma (POAG) followed(More)
To determine the yield of brain biopsy and the predictive value of clinical features and ancillary studies, we retrospectively analyzed hospital chart data from 61 consecutive patients suspected of having primary angiitis of the CNS (PACNS). Biopsies disclosed PACNS in 22 (36%), alternative diagnoses in 24 (39%), and no diagnosis in 15 (25%). Clinical(More)
OBJECTIVE To review the published literature on deep anterior lamellar keratoplasty (DALK) to compare DALK with penetrating keratoplasty (PK) for the outcomes of best spectacle-corrected visual acuity (BSCVA), refractive error, immune graft rejection, and graft survival. METHODS Searches of the peer-reviewed literature were conducted in the PubMed and the(More)
BACKGROUND The relationship between the circumstances and severity of closed head injury (CHI) and the clinical and imaging features of cranial nerve 3, 4, and 6 palsies has not been rigorously addressed in a large study. METHODS Retrospective chart review of 210 consecutive patients with CHI examined at a single tertiary care center from 1987 to 2002.(More)
PURPOSE To measure and contrast 2 biomarkers of cardiovascular disease, C-reactive protein (CRP) and plasma homocysteine, in individuals with age-related macular degeneration (AMD) and control individuals without AMD. DESIGN Case-control study. PARTICIPANTS Seventy-nine affected individuals and 77 unaffected individuals from the AMD Genetic Study Group(More)
PURPOSE Previous in vitro studies with transgenic and gene-knockout mice have shown that lenses with elevated levels of glutathione peroxidase (GPX)-1 activity are able to resist the cytotoxic effect of H(2)O(2), compared with normal lenses and lenses from GPX-1-deficient animals. The purpose of this study was to investigate the functional role of this(More)
PURPOSE To develop and characterize a heterozygous knock-in mouse model carrying the 5-bp deletion in Elovl4 (E_mut+/-) and to study the pathology underlying Stargardt-like macular degeneration (STGD3). METHODS E_mut+/- mice were generated by targeting a 5-bp deletion (AACTT) in the Elovl4 gene by homologous recombination. E_mut+/- mice of age 2 to 18(More)
