It is light-sensitive and communicates visual messages to the brain. If the retina detaches, it moves and shifts from its normal position. This can cause photopsia, but can also cause permanent vision loss. Medical attention is needed to prevent vision loss. Procedures may include laser treatment, freezing, or surgery.
Diffraction spikes are lines radiating from bright light sources, causing what is known as the starburst effect [1] or sunstars [2] in photographs and in vision. They are artifacts caused by light diffracting around the support vanes of the secondary mirror in reflecting telescopes , or edges of non-circular camera apertures , and around ...

An arc of light may gradually enlarge, become more obvious, and may take the form of a definite zigzag pattern, sometimes called a fortification spectrum (i.e. teichopsia , from Greek τεῖχος, town wall), because of its resemblance to the fortifications ...

The costs of a mesotherapy treatment depend on the desired areas to be treated. For instance, Elite Aesthetics , a clinic based in the UK, offers treatments for £300 (approximately $380).
It is difficult to resolve visual snow with treatment, but it is possible to reduce symptoms and improve quality of life through treatment, both of the syndrome and its comorbidities. [4] In some studies, lamotrigine as a treatment for visual snow syndrome only showed efficacy in 20% of patients, and in one study, patients using lamotrigine ...
