ENTOPTIC Meaning and
Definition

Entoptic:
Entoptic is an adjective that describes phenomena or visual experiences that originate within the eye itself, rather than being caused by external sources. The term 'entoptic' can be traced back to the Greek words 'entos', meaning 'within', and 'optos', meaning 'seen'. It is commonly used in the fields of ophthalmology, optometry, and perceptual psychology to elucidate a variety of visual occurrences that arise as a result of the eye's own structures and processes.
The entoptic phenomenon includes a range of visual phenomena that individuals perceive as flickering or floating shapes and patterns in their visual field, without any external stimuli. These entoptic experiences often manifest as intricate geometric shapes, such as lines, dots, or spirals, moving around or blinking in and out of vision. Some common examples of entoptic phenomena include the appearance of eye floaters, which are tiny specks or threads that seem to float across one's visual field, or the visibility of blood vessels within the eye's own retina.
Entoptic phenomena can be induced through different causes, such as eye fatigue, disruption of the vitreous humor (the gel-like substance that fills the eye), retinal detachment, or pressure changes within the eye. They can also be observed under specific conditions, like when staring at a blank wall or closing one's eyes while applying pressure to the eyelids. Understanding and studying entoptic phenomena are crucial for differentiating between normal ocular phenomena and potential vision-threatening conditions.
