Provocative test combining water drinking and homatropine eye drops
نویسنده
چکیده
In a previous study (Leighton, Phillips, and Gibbs, 1970), a provocative outflow test using a combination of water drinking (20 ml./kg. body weight) and gutt. homatropine 2 per cent. in 24 open-angle glaucoma suspects caused a significantly greater fall in outflow facility and rise in outflow resistance than either water drinking alone or homatropine alone (0o02 < P < o0os in each case). When applanation tension was considered, water drinking combined with gutt. homatropine again gave the greatest rise; this was again significantly greater than the rise in applanation tension after either water alone or gutt. homatropine alone (P < o.oi in each case). This less marked inter-test difference in change in outflow (i.e. 0f02 < P < 0o05) compared with change in applanation tension (i.e. P <ooi) is likely to have been due to a wider scatter of tonographic than of tonometric readings. The difference between mean rise in applanation tension and mean rise in outflow resistance cannot unfortunately be compared statistically because they are expressed in different units.

Weekers, Lavergne, and Prijot (1958), Davenport (I959), and Perkins and Jay (I960) have all commented on a high incidence of myopia in open-angle glaucoma. Abdalla and Hamdi (1970) showed that myopic eyes have higher ocular tensions than emmetropic eyes in most age groups. The findings of Tomlinson and Phillips (1970) agreed with this, but showed that ocular tension correlated more closely with...
متن کاملEvaluation of laser iridectomy in angle-closure glaucoma: provocative tests.
An argon laser iridectomy was performed on 18 eyes of 14 patients with closed-angle glaucoma. The intraocular pressure (IOP) was controlled in all but one eye within normal limits. Variable amounts of pigment were found on gonioscopy in all cases. The mydriasis test was positive in one eye (5.5%) after homatropine and in 5 eyes (28%) after tropicamide drops. 80% of the positive results occurred...

OBJECTIVES A prospective study to evaluate the changes in A-Scan axial parameters of phakic normal eyes before and after instillation of 1% topical Tropicamide and 2% Homatropine eye drops. METHODS Anterior chamber depth, lens thickness, vitreous chamber length, and ocular axial length were measured in 76 eyes before and after cycloplegia induced by 1% topical Tropicamide, and in 28 eyes with...

PURPOSE To assess the effect of homatropine eye drops on pain after photorefractive keratectomy (PRK). METHODS This randomized, double masked, interventional study included 15 patients (30 eyes) who underwent bilateral PRK. After operation, patients received homatropine eye drops, 4 times daily in only one eye (homatropine eye). The level of pain was evaluated using visual analogue scale (VAS...
