purpose: to compare anterior segment and ocular biometric parameters of unaffected fellow eyes of patients with a previous attack of acute angle closure (aac), primary angle closure suspect (pacs) eyes, and normal eyes; and to assess the risk of developing aac in pacs. methods: in this prospective comparative observational case series, 16 unaffected fellow eyes of patients with a previous attac...
Primary open angle glaucoma (POAG), a major cause of blindness worldwide, is a complex disease with a significant genetic contribution. We performed Exome Array (Illumina) analysis on 3504 POAG cases and 9746 controls with replication of the most significant findings in 9173 POAG cases and 26 780 controls across 18 collections of Asian, African and European descent. Apart from confirming strong...
Comparative efficacy of orally and topically administered beta blockers for chronic simple glaucoma.
This open study of beta blockers in chronic simple glaucoma compared the efficacy of once daily (o.d.) oral nadolol therapy with twice daily (b.d.) topical timolol therapy. Sixty eight patients were randomly assigned to starting doses of either 20, 40, or 80 mg of nadolol o.d. (51 patients) or 0.25% timolol b.d. (17 patients) and were seen at weekly intervals for a four-week (short-term) period...
OBJECTIVE The aim of this study was to evaluate the effectiveness of prenatal screening for trisomy 18 with the use of the frontomaxillary facial angle (FMF angle) measurement. MATERIAL AND METHODS The study involved 1751 singleton pregnancies at 11-13 + 6 weeks, examined between 2007 and 2011. Serum PAPP-A and free beta-hCG levels were assessed, and crown-rump length, nuchal translucency, an...
C17H19O2N5 is monoclinic, P2(1)/n. Unit-cell dimensions at 293 K are a = 10.802(1), b = 24.085(2), c = 12.933(1)A, beta = 106.119(6) degrees, V = 3232.4(6)A3, Dx = 1.271 g/cm3, and Z = 8. The R value is 0.068 for 3017 observed reflections. There are two independent molecules in the asymmetric unit, denoted by A and B. In A, the dihedral angle between the adenine moiety and the phenyl ring is 73...
PURPOSE To evaluate the effect of treatment for 3 years with a dorzolamide/timolol (1%/0.5%) fixed combination (DTFC) on visual field progression in patients with open-angle glaucoma. PARTICIPANTS A total of 14 consecutive patients were enrolled who had been previously treated with monotherapy or any combination of a beta blocker, carbonic anhydrase inhibitor, and/or prostaglandin analog for ...
This is a critical abstract of an economic evaluation that meets the criteria for inclusion on NHS EED. Each abstract contains a brief summary of the methods, the results and conclusions followed by a detailed critical assessment on the reliability of the study and the conclusions drawn. Dorzolamide hydrochloride, a topically administered carbonic anhydrase therapy inhibitor for patients with p...
BACKGROUND The purpose of this study was to evaluate corneal parameters in treated glaucoma patients, nontreated glaucoma patients, and normal subjects using confocal microscopy. METHODS Forty patients with primary open-angle glaucoma and 22 untreated controls underwent confocal microscopy of the cornea using the Heidelberg retinal tomograph cornea module. The glaucoma group was divided into ...
