OBJECTIVE To investigate potential risk factors associated with incident nuclear, cortical, and posterior subcapsular (PSC) cataracts and cataract surgery in participants in the Age-Related Eye Disease Study (AREDS). DESIGN Clinic-based prospective cohort study. PARTICIPANTS Persons (n = 4425) 55 to 80 years of age enrolled in a controlled clinical(More)
In this article, we provide the results of experimental studies demonstrating that corneal avascularity is an active process involving the production of anti-angiogenic factors, which counterbalance the pro-angiogenic/lymphangiogenic factors that are upregulated during wound healing. We also summarize pertinent published reports regarding corneal(More)
PURPOSE The aim of this study was to determine and characterize the effect of topical application of benzalkonium chloride (BAK) on corneal nerves in vivo and in vitro. METHODS Thy1-YFP+ neurofluorescent mouse eyes were treated topically with vehicle or BAK (0.01% or 0.1%). Wide-field stereofluorescence microscopy was performed to sequentially image the(More)
PURPOSE We determined Semaphorin 7a (Sema7a) localization and abundance in naive corneas and in corneas after nerve-transecting lamellar flap surgery, and determined the effect of Sema7a supplementation on corneal nerve regeneration and inflammation. METHODS Immunolocalization and Western blot analyses were performed to evaluate the abundance of Sema7a in(More)
PURPOSE To compare the visual and refractive outcomes of laser epithelial keratomileusis (LASEK) and laser in situ keratomileusis (LASIK) for the treatment of low to moderate myopia. DESIGN Retrospective, nonrandomized, control-matched study. METHODS The charts of 2257 eyes that underwent LASEK or LASIK treatment were reviewed. Patients who were 21(More)
PURPOSE We characterized fluorescent bone marrow cells (YFP(+) BMCs) in the thy1-YFP mouse and determine if they promote trigeminal ganglion (TG) cell neurite growth. METHODS Excimer laser annular keratectomy was performed in thy1-YFP mice, and corneas were imaged. BMCs were harvested from femur and tibia, and the expression of surface markers on YFP(+)(More)
PURPOSE To measure depressive symptoms in patients with dry eye disease (DED) and controls using the Beck Depression Inventory (BDI) and to determine the association between depressive and DED symptoms. METHODS Fifty-three patients with DED and 41 controls were recruited to the study. DED symptoms were assessed using the Symptom Burden Tool and Ocular(More)
PURPOSE To identify single nucleotide polymorphisms (SNPs) in the brain-derived neurotrophic factor (BDNF), vitamin D receptor (VDR), and DNASE1 genes that may be associated with dry eye disease (DED), and determine whether this association varies by the presence of depression. METHODS A case-control study was performed with 64 DED cases and 51 controls.(More)
PURPOSE To determine which sensory (symptom persistence and intensity) and reactive (activity and affective interference) domains of symptom analysis are essential for assessing symptom burden in dry eye disease (DED) patients. METHODS A symptom domain tool was developed to investigate all four symptom domains in DED. In a cross-sectional pilot study, we(More)
PURPOSE To compare the refractive and visual outcomes of sub-Bowman keratomileusis (SBK) and thick-flap laser in situ keratomileusis (LASIK) for moderate to high myopia and evaluate the effect of corneal flap thickness on outcomes. SETTING Massachusetts Eye and Ear Infirmary, Boston, Massachusetts, USA. METHODS Two studies were performed. In the first(More)
