A technique for accurate application of pilocarpine gel.
Pilocarpine hydrochloride 4% gel can be accurately administered by squeezing a one-half inch ribbon of gel onto the tube tip and then touching the premeasured dose to the conjunctiva.

Momentary fluctuations of intraocular pressure in normal and glaucomatous eyes.
To examine the range of momentary fluctuations of intraocular pressure caused by vascular pulsations in 42 glaucomatous and 18 normal eyes, we obtained consecutive intraocular pressure measurements at hourly intervals with a noncontact air tonometer. Glaucomatous eyes had a significantly (P less than .001) greater range of intraocular pressure measurements on consecutive readings than normal eyes (4.4 +/- 1.4 mm Hg vs 2.7 +/- 0.7 mm Hg). The frequency of consecutive intraocular pressure readings exceeding a spread of 4 mm Hg was significantly increased in glaucomatous eyes. The range of intraocular pressure measurements was greater even in those glaucomatous eyes with mean intraocular pressures within the normal range. There was a positive correlation between mean intraocular pressure and mean range in glaucomatous eyes, but not in normal eyes. In both glaucomatous and normal eyes, there was no significant correlation between age and mean range.
