The investigators found statistically significant physician satisfaction with the use of mannitol as a bladder distention medium over oral phenazopyridine, and slightly better satisfaction compared with the use of intravenous sodium fluorescein
or normal saline distention.
1 mL of 10% sodium fluorescein
IV during cystoscopies performed at the end of gynecologic surgeries, measuring the time to visualization and the level of satisfaction with the dye.
A serial dilution of the standard solution of 5 ppm of sodium fluorescein
tracer was prepared to plot the linear calibration curve and determine the detection limit of the device.
Forty-eight hours after PCB treatment (150 [micro]mol/kg), we observed a statistically significant increase in sodium fluorescein
permeability across the capillary endothelium in all treatment groups (Figure 4).
IVFA involves injecting sodium fluorescein
into systemic circulation followed by serial retinal photography to image the movement of the fluorescent dye in retinal vasculature and out of the vessels in pathology (see Figure 2)
Optometrists and contact lens fitters in routine practice frequently use sodium fluorescein
for clinical assessment.
Under conditions where there is insufficient sodium fluorescein
(NaFl), poor illumination, or NaFl quenching, the inner edge will appear to be at a different location resulting in IOP underestimation.
is orange in colour, and when diluted in an aqueous solution is excited by short wavelength light (blue), to emit a green coloured light at a maximum intensity of 525-530nm.
b) Instillation of lissamine green and sodium fluorescein
to check for staining
It is important to examine the ocular surface with the instillation of sodium fluorescein
a) Assessment of corneal sensitivity b) Sodium fluorescein
staining c) Rose bengal staining d) Intraocular pressure measurement
a) Blue filter for sodium fluorescein
assessment of the tear film b) Placido disc filter for assessment of corneal shape c) A filter for assessment of tear osmolarity d) Grid filter for measurement of non-invasive tear break-up time (NIBUT)
There is no obvious 'drying' effect from use of these drugs on the corneal and conjunctival epithelium (eg, as evidenced by sodium fluorescein
staining) but patients with chronic allergic conjunctivitis are more likely to have low grade staining and lower fTBUT values.
