Laser treatment is delivered through the front of the eye using either a head-mounted apparatus or a laser apparatus connected to a slit lamp in conjunction with a contact lens. The scar can be created by either laser treatment or a freezing treatment, depending on the location and characteristics of the tear. This scar serves to weld the retina and seal it to the underlying tissues, thereby preventing fluid from moving through the retinal tear into the space under the retina (retinal detachment). The goal of treatment is the creation of a controlled scar surrounding the retinal tear. Retinal tears may also occur after trauma or surgery in the eye. Who are very near-sighted patients with a family history of retinal tear or retinal detachment or patients with a prior retinal tear or detachment in the same or other eye. Retinal tears are more common in patients ![]() If the retina is unusually thin or damaged, the gel pulling may be enough to cause a full thickness tear in the retina. This process usually starts near the back and continues towards the front of the eye, with traction on the retina at the leading edge. A defect in the retina, such as a tear, can allow fluid to enter the space behind the retina, causing a retinal detachment and vision loss.Īs the vitreous gel changes with age, it may pull away from the retina in the back of the eye. ![]() While the process of vitreous separation is common and typically uneventful, in some cases the vitreous gel surface pulls on the retina as it separates, resulting in a tear. The inside of the eyeball is filled with a gel called the vitreous, and with age and time the surface of the vitreous gel can separate from the retina. The retina is the sensor tissue that lines the inside back of the eye. The eye is like a camera, with a lens in the front and a sensor or film in the back.
