Additionally, the use of the TV minimized complications in acquiring readings for birds with constantly mobile nictitating

Blink and nictitating membrane reflexes frequently corresponded in their responses to stimuli.
First indicators of consciousness to weaken and fail are responses to pinching of the skin of the head, followed by pupillary and reflexes of the blink and nictitating membranes.
And sharks have a nictitating
membrane that protects their eyes while they feed.
4) In birds, the nictitating
membrane, which lies in the dorsonasal quadrant of the conjunctival sac, is a thin membrane that moves swiftly over the surface of the cornea.
A diffuse, yellow-white plaque was present over 90%-95% of the cornea, and the nictitating membrane was unable to move normally across the surface of the globe because of the presence of the plaque.
There was no change in the blepharedema or in the mobility of the nictitating membrane.
We suggest that several previous studies may underreport prevalence and abundance because in those studies only the eye surface and nictitating
membrane were examined and not eye-associated tissue, ducts, glands, or sinuses.
membrane originated dorsomedially and swept laterally across the globe.
Ocular neoplasia in birds has been reported infrequently, and solitary tumors of the nictitating
membrane even less so.
Because metaplasia of the gland of the nictitating
membrane caused by hypovitaminosis A could not be excluded as a differential diagnosis, therapy with vitamin A (Vitamin A Streuli, Streuli Pharma AG, Uznach, Switzerland) was initiated at 6000 IU/kg IM once, followed by 500 IU/kg IM for 3 days and 200 IU/kg IM for another 3 days.
