The flashing suggests that the vitreous is pulling on the retina, potentially causing a tear. What are the early signs of a torn or detached retina?Ī common warning sign of a retinal tear or detachment is seeing flashes of light (like a camera flash), which can be noticed in dark conditions or when you move your head from side to side. Other less common causes of retinal detachment include inflammation, tumors and diseases like diabetes, but those cases are treated differently than rhegmatogenous or trauma-related tears and detachments.
In such cases, a retinal tear can develop and lead to a retinal detachment.

This hole allows fluid to pass through and lift or separate the retina, causing a full detachment.Ī second common cause of retinal detachment is trauma, or injury, to the eye. As this occurs, the vitreous can pull on the retina and create a hole, or tear. This happens when gel-like fluid inside the eyes, called the vitreous, starts to liquify or shrink with age. There are multiple ways that the retina can detach, but the most common way is called a rhegmatogenous retinal detachment. When the retina is detached from the back wall of the eye, it separates from its blood supply and no longer functions properly, resulting in decreased vision. What is a retinal detachment and how does it occur?Ī retinal detachment is when the retina – a layer of the eye tissue that senses light and sends images to the brain – is separated or lifts away from the back of the eye. Focus spoke with retina surgeon Mohammad Dahrouj, MD, PhD, about the causes of retinal detachments and why it’s important to immediately seek medical attention if certain symptoms arise. Retinal detachments and tears can lead to the loss of sight and should be treated as emergencies.
