The first half of the word, "gutta," is pronounced with a short "u" sound like "uh," followed by a "t" sound and a long "a" sound like "ay."

Gutta Serena is a Latin term that translates to "blind drop" or "drop without sight" in English. It is a term used in ophthalmology to describe a condition known as congenital stationary night blindness.
Congenital stationary night blindness is a rare genetic disorder that affects the vision of individuals from a young age. Those with this condition typically have impaired or non-existent night vision, as well as reduced visual acuity under low-light conditions. However, their daytime vision remains relatively normal.
The term Gutta Serena implies the absence of visual perception in the dark or without ample light, indicating the lack of ability to see in such environments. It is named "drop" due to the common resemblance of a tear drop on the ocular surface, symbolizing the inability to perceive visual stimuli in certain conditions.
This condition is believed to be caused by abnormalities in the retinal cells, particularly the photoreceptor cells that are responsible for detecting light and transmitting visual information to the brain. It can be inherited through an autosomal dominant or autosomal recessive pattern, but can also occur spontaneously through gene mutations.
Overall, Gutta Serena encapsulates the medical term used to describe the congenital vision impairment known as congenital stationary night blindness, highlighting the inability to perceive visual stimuli in dimly lit or darkened settings.
A loss or decay of sight from palsy of the optic nerve without any apparent blindness.
