Ocular pulse amplitude in diabetes mellitus.

چکیده
BACKGROUND The influence of diabetes mellitus on ocular pulse amplitude (OPA), an indirect measure of choroidal perfusion, is unclear. METHODS OPA, using the Langham ocular blood flow (OBF) system, applanation intraocular pressure (IOP), systemic blood pressure (BP), heart rate, and haemoglobin (Hb) A(1c) were measured in patients with insulin dependent diabetes mellitus (IDDM) with no (DR-0, n = 22) non-proliferative (DR-1, n = 24), and proliferative (DR-2, n = 18) diabetic retinopathy. RESULTS Neither local (OPA, IOP) nor systemic perfusion parameters (BPs, HR) nor HbA(1c) were significantly altered in DR-0, DR-1, or DR-2 IDDM patients. CONCLUSION Choroidal circulation remains unaffected as diabetic retinopathy advances.

Evaluation of ocular pulse amplitude in non-arteritic anterior ischaemic optic neuropathy
BACKGROUND To evaluate the ocular pulse amplitude (OPA) in patients with chronic non-arteritic anterior ischaemic optic neuropathy (NAION). METHODS This cross-sectional study comprised a study group of 30 eyes from 30 patients with NAION and a control group of 31 eyes from 31 age and gender-matched healthy subjects. Bilateral OPA was measured with dynamic contour tonometry (DCT) and was compa...
متن کاملAmplitude of the ocular pneumoplethysmography waveform is correlated with cardiac output.
BACKGROUND AND PURPOSE Ocular pulse amplitude, the amplitude of the ocular pneumoplethysmographic waveform, is altered in several ophthalmologic diseases that disturb ocular blood flow, implying that ocular pulse amplitude may provide an estimate of ocular blood flow. Because ocular blood flow currently cannot be quantified in humans, two experiments were undertaken to evaluate the association ...
متن کاملPhotoelectric plethysmography. Ocular blood flow measurements in dogs.
Ocular blood flow in dogs was monitored loith the use of a specially designed photoelectric plethysmograph transducer. The ocular pulse waves demonstrated were (1) of low amplitude, (2) coincident with cardiac systole, and (3) rapidly affected by stimuli known to influence cerebral blood flow. Changes in ocidar pulse amplitude correlated ivith concurrent blood gas analyses (arterial COi and O!)...
متن کاملOcular haemodynamics and colour contrast sensitivity in patients with type 1 diabetes.
BACKGROUND There is evidence that altered ocular blood flow is involved in the development and progression of diabetic retinopathy. However, the nature of these perfusion abnormalities is still a matter of controversy. Ocular haemodynamics were characterised with two recently introduced methods. METHODS The cross sectional study was performed in 59 patients with type 1 diabetes with a diabete...
متن کاملThe heritability of corneal hysteresis and ocular pulse amplitude: a twin study.
PURPOSE To examine the roles of genetic and environmental factors in corneal hysteresis and ocular pulse amplitude by performing a classic twin study. DESIGN Cross-sectional twin study. PARTICIPANTS AND/OR CONTROLS Two hundred sixty-four twin pairs: 135 monozygotic (MZ) and 129 dizygotic (DZ). METHODS Corneal hysteresis was measured using the Reichert Ocular Response Analyzer (ORA; Reiche...
