A fotocoagulação a laser da retina dói?

Does the laser photocoagulation procedure hurt? In today's video, Dr. Mário Bulla, an ophthalmologist and retinologist, will talk about this procedure that is so important and so frequently performed. Laser photocoagulation is a very traditional treatment; in fact, it has been around for decades. Of course, the equipment has been evolving and becoming more precise, but it's not a treatment that has recently emerged, quite the contrary. One concern that patients always have regarding this procedure is whether or not it will hurt, because in practice it is a very common procedure that can be done in the office itself. After all, it doesn't require deeper anesthesia, just the use of eye drops, and the patient can go home after the procedure. What ends up bothering people the most is actually the dilation of the pupil itself, because vision ends up being blurred for a few hours after the procedure. But regarding pain during laser photocoagulation, it's a question that's even difficult to answer because sensitivity to the procedure varies greatly from one patient to another, and even when undergoing the procedure. no with the same device and with the same parameters, there are patients who report no pain at all and there are patients who report quite significant pain, often considering the procedure almost unbearable. Fortunately, this extreme situation is not so common, and the vast majority of patients are able to tolerate the laser procedure with relative ease. Although it's a procedure that isn't so pleasant, after all, a very intense light is flashing inside the patient's eye, since the laser is applied gradually, the doctor can adjust the parameters according to the patient's sensitivity. So perhaps a patient with lower sensitivity allows for a faster application with greater intensity, while in the case where the person has a little more sensitivity, the laser can be applied more slowly and with slightly lower parameters. But there really is no way to answer this question absolutely; it will depend a lot on each patient. Rarely, there are extreme cases where the person really cannot tolerate the laser application, and in these cases, it may be possible to perform a peribulbar block, that is, to apply anesthesia around the eye. This is usually done by an anesthesiologist, and after this peribulbar block, the laser is applied. But since peribulbar anesthesia is already a somewhat more invasive procedure, if the patient has good tolerance to the laser application, the ideal is to do it only with the use of eye drops, the anesthetic drops that are used for The laser actually aims to anesthetize the ocular surface to allow contact with the lens we use to apply the laser, that is, to reduce the sensitivity of the cornea and conjunctiva to allow the contact lens we use to apply the laser to rest against the eye. However, the pain caused by the laser originates behind the retina, and for these cases, a deeper anesthesia called peribulbar block or a similar anesthesia called subtenon block is necessary.
