Kergoat H, Forcier P
Doc Ophthalmol . 1996 Jan; 92(3):145-57. PMID: 9181342
Although the effects of physical exertion on intraocular pressure and systemic blood pressure are well established, the retinal response to such physiologic stress has not been examined. We studied the...

Kergoat H, Lovaski J
Optom Vis Sci . 1995 Apr; 72(4):249-57. PMID: 7609950
Purpose: Using blue field entoptoscopy, we have recently shown that blood flow in the paramacular capillaries remained constant after moderate exercise. In the present study, our objective was to identify...

Lovasik J, Kergoat H
Aviat Space Environ Med . 1994 Nov; 65(11):1010-4. PMID: 7840740
We quantified the changes in macular and choroidal blood flow during body inversion to elaborate their hemodynamic attributes and relate them to our previously reported effects of inversion on visual...

Kergoat H, Lovasik J
Ophthalmic Physiol Opt . 1994 Oct; 14(4):401-7. PMID: 7845699
Autoregulation (AR), the capacity of retinal vessels to maintain a constant flow of blood during alterations in vascular perfusion pressure, has been studied by a variety of techniques. Psychophysical and...

Lovasik J, Gagnon M, Kergoat H
Surv Ophthalmol . 1994 May; 38 Suppl:S35-51. PMID: 7940147
Vision loss in glaucoma may be due to the compressive effects of the intraocular pressure (IOP) on the ganglion cell axons, impaired blood flow to the optic nerve, or some...

Lovasik J, Kothe A, Kergoat H
Optom Vis Sci . 1993 Dec; 70(12):1005-11. PMID: 8115122
Purpose: The pressure within the ophthalmic artery can be estimated by several noninvasive procedures based on measurements of the pressure either within the central retinal artery (CRA) or the brachial...

Kergoat H
Optom Vis Sci . 1993 Sep; 70(9):743-9. PMID: 8233370
Purpose: The oscillatory potentials (OP's) of the flash-elicited electroretinogram (ERG) are vulnerable to changes in retinal circulation such as occur in insulin-dependent diabetes mellitus (IDDM). In an earlier study it...

Lovasik J, Kergoat H
Invest Ophthalmol Vis Sci . 1993 Apr; 34(5):1731-43. PMID: 8473113
Purpose: Although functional changes in vision are known to occur before overt diabetic retinopathy, the relationship between (1) the degree and timing of any visual dysfunction and (2) the duration...

Lovasik J, Kothe A, Kergoat H
Doc Ophthalmol . 1993 Jan; 84(3):201-11. PMID: 8119100
Several studies have investigated the effect of elevated intraocular pressure with reduced ocular perfusion pressure on visual neural function by means of compression and suction ophthalmodynamometry. We compared the effects...

Lovasik J, Kothe A, Kergoat H
Optom Vis Sci . 1992 Feb; 69(2):85-94. PMID: 1584558
In this report we present the results of a series of studies focusing on the effects of transient changes in the ocular perfusion pressure (OPP) on retinal function in normals...
