All patients were operated by a single surgeon and IOP was measured after first post-operative day, and after intervals of first week, second week, one month and forty days using applanation tonometry (AT) and fluorescein dye
. A single post-operative reading of up to 6 mmHg measured and verified with AT was labeled as hypotony.
I commended him for this; sat him on the examination chair and instilled some drops of topical anaesthetic agent followed by a drop of fluorescein dye
into the affected eye.
A delay in the arm-to-retina time may reflect a problem with the fluorescein dye
injection or circulatory problems with the patient including heart and peripheral vascular disease.
Standard Cyclops sensors are available for detecting: in vivo Chlorophyll, Crude Oil, Refined Fuels, CDOM/FDOM (dissolved organic material), Blue/Green Algae, Fluorescein Dye
, Rhodamine Dye, PTSA Dye, Optical Brighteners, Tryptophan, and Turbidity.
The neurosurgery team placed a lumbar drain and dilute fluorescein dye

staining of the tear film on Scheimpflug measurements of central corneal thickness," Cornea, vol.
With Coast Guard personnel and ADAC Director Kee aboard the research vessel Discovery, they pumped a stream of bright-green fluorescein dye
, a harmless mimic for oil, into Buzzards Bay off Cape Cod.
Conjunctival and corneal epithelial erosions are stained with fluorescein dye
(fluorescein invades the sites of disruption between cell junctions).
Leakage of fluorescein dye
occurs in cases of increased capillary permeability and is considered a marker for BRB breakdown in DR .
OCT-A carries the additional advantage of being noninvasive and avoiding potential rare side effects such as anaphylaxis from fluorescein dye
FL is an easily available and biosafe fluorescein dye
with a peak excitation at 465 to 490 nm and emission between 500 and 550 nm and has been used extensively and safely for many years especially in ophthalmology [7, 8].
Fluorescein tear break-up (FTBUT): This commonly used clinical method involves instilling fluorescein dye
into the eye and illuminating the tear film using a slit lamp and a cobalt blue filter.
