Ocular pulse amplitude in patients with open angle glaucoma, normal tension glaucoma, and ocular hypertension
Background/aim: Intraocular pressure (IOP) is not a fixed constant value but rather has pulsatile components associated with cardiac action. The SmartLens dynamic observing tonometer (odc, Ophthalmic Development Company AG, Zurich, Switzerland) can measure and record simultaneously IOP and ocular pu...

| description | Background/aim: Intraocular pressure (IOP) is not a fixed constant value but rather has pulsatile components associated with cardiac action. The SmartLens dynamic observing tonometer (odc, Ophthalmic Development Company AG, Zurich, Switzerland) can measure and record simultaneously IOP and ocular pulse amplitude (OPA). It was the aim of this study to evaluate OPA in patients with primary open angle glaucoma (POAG) and high IOP, normal tension glaucoma (NTG), and ocular hypertension (OHT). Furthermore, the authors examined whether there were any correlations with blood pressure. Methods: 80 subjects were divided into four groups (n=20): 20 patients each with POAG, NTG, and OHT and 20 volunteers without any ocular pathology except for cataract served as a control group. Results: The OPA of the POAG group was not statistically significant different from the control group and from the OHT group. However, OPA was statistically significant lower (p |

However, OPA was statistically significant lower (p<0.01) in the NTG group compared with all other groups. The OPA of the OHT group was slightly higher compared to the healthy volunteers (p=0.09) and to the POAG patients (p=0.09). No statistically significant correlations with blood pressure could be detected. A logistic regression model was established which identified OPA as an independent risk factor for NTG. Conclusions: The study demonstrated a decrease in OPA of patients suffering from NTG. Thus, measuring of OPA by the SmartLens dynamic observing tonometer could be helpful in the detection of NTG patients.</description><identifier>ISSN: 0007-1161</identifier><identifier>EISSN: 1468-2079</identifier><identifier>DOI: 10.1136/bjo.86.9.981</identifier><identifier>PMID: 12185121</identifier><identifier>CODEN: BJOPAL</identifier><language>eng</language><publisher>BMA House, Tavistock Square, London, WC1H 9JR: BMJ Publishing Group Ltd</publisher><subject>Adult ; Age ; Age Factors ; Aged ; Aged, 80 and over ; Biological and medical sciences ; Blood Pressure ; Care and treatment ; Female ; Glaucoma ; Glaucoma - physiopathology ; Glaucoma and intraocular pressure ; Glaucoma, Open-Angle - physiopathology ; Humans ; Hypertension ; Intraocular pressure ; Intraocular Pressure - physiology ; IOP ; Male ; Measurement ; Medical sciences ; Middle Aged ; normal tension glaucoma ; NTG ; ocular hypertension ; Ocular Hypertension - physiopathology ; Ocular manifestations of general diseases ; ocular pulse amplitude ; OHT ; OPA ; Open-angle glaucoma ; Ophthalmology ; Patients ; POAG ; primary open angle glaucoma ; Retinopathies ; Scientific Correspondence ; Statistical analysis ; Studies ; tonometer ; Tonometry, Ocular</subject><ispartof>British journal of ophthalmology, 2002-09, Vol.86 (9), p.981-984</ispartof><rights>Copyright 2002 British Journal of Ophthalmology</rights><rights>2002 INIST-CNRS</rights><rights>COPYRIGHT 2002 BMJ Publishing Group Ltd.</rights><rights>Copyright: 2002 Copyright 2002 British Journal of Ophthalmology</rights><rights>Copyright © Copyright 2002 British Journal of Ophthalmology 2002</rights><lds50>peer_reviewed</lds50><oa>free_for_read</oa><woscitedreferencessubscribed>false</woscitedreferencessubscribed><citedby>FETCH-LOGICAL-b626t-c26bd2df76f586fce12d898832f558694b477b31217cc77c88fc79e861fedf593</citedby></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><linktopdf>$$Uhttps://www.ncbi.nlm.nih.gov/pmc/articles/PMC1771281/pdf/$$EPDF$$P50$$Gpubmedcentral$$H</linktopdf><linktohtml>$$Uhttps://www.ncbi.nlm.nih.gov/pmc/articles/PMC1771281/$$EHTML$$P50$$Gpubmedcentral$$H</linktohtml><link.rule.ids>230,314,723,776,780,881,27901,27902,53766,53768</link.rule.ids><backlink>$$Uhttp://pascal-francis.inist.fr/vibad/index.php?action=getRecordDetail&idt=13843451$$DView record in Pascal Francis$$Hfree_for_read</backlink><backlink>$$Uhttps://www.ncbi.nlm.nih.gov/pubmed/12185121$$D View this record in MEDLINE/PubMed$$Hfree_for_read</backlink></links><search><creatorcontrib>Schwenn, O</creatorcontrib><creatorcontrib>Troost, R</creatorcontrib><creatorcontrib>Vogel, A</creatorcontrib><creatorcontrib>Grus, F</creatorcontrib><creatorcontrib>Beck, S</creatorcontrib><creatorcontrib>Pfeiffer, N</creatorcontrib><title>Ocular pulse amplitude in patients with open angle glaucoma, normal tension glaucoma, and ocular hypertension</title><title>British journal of ophthalmology</title><addtitle>Br J Ophthalmol</addtitle><description>Background/aim: Intraocular pressure (IOP) is not a fixed constant value but rather has pulsatile components associated with cardiac action.
