This study evaluated pupillary postganglionic autonomic dysfunction and its relationship to visual disturbance in idiopathic Parkinson's disease (PD). Pupillary sensitivity was examined in relation to a parasympathomimetic agent [0.05% pilocarpine hydrochloride (PL)] and to a sympathomimetic agent [0.02% dipivefrine hydrochloride (DPE)] using infrared pupillography in 40 PD patients and 17 age-matched controls. Visual disturbances were evaluated as well, including blurring, photophobia, night blindness and involuntary eyelid closure in response to light. Pupillary supersensitivity to PL and DPE and their relation to visual disturbances were found to be significantly greater in PD patients than in controls (22.3 +/- 15.1 vs. 10.4 +/- 11.4%, P < 0.005, and14.5 +/- 14.5 vs. 4.9 +/- 8.7%, P < 0.01, respectively). In addition, pupillary sympathetic supersensitivity did not correlate with a reduction of 123I-metaiodobenzylguanidine (MIBG) cardiac accumulation.
3.Latanoprost: new preparation. Antiglaucoma eye drops that can change the colour of the iris.
Prescrire Int. 1998 Dec;7(38):166-8.
(1) Latanoprost, a prostaglandin F2 alpha analogue, is an antiglaucoma drug. (2) The clinical file is fairly thorough. (3) Dose-finding studies show that the optimal daily dose is a single drop of 0.005% solution, preferably in the evening. Two drops a day are less effective than one drop a day. (4) The local hypotensive action of latanoprost persists in the long term (current follow-up one year). (5) Four double-blind trials have compared 0.005% latanoprost eye drops and 0.5% timolol eye drops. In three trials the effect of latanoprost on intraocular pressure was statistically stronger than that of timolol. However, the difference in mean intraocular pressure was less than 2 mm Hg between the two treatments, and the clinical relevance of such a difference is not known. (6) Latanoprost has not been compared with the other available antiglaucoma eye drops. (7) Various trials have shown that intraocular pressure is statistically lower when latanoprost is combined with another antiglaucoma eye drop preparation (timolol, pilocarpine or dipivefrine) than during monotherapy.
