Dermal Fillers

When Does Blindness Occur After Fillers

Blindness is one of the rare complications associated with filler treatment. This article explains when blindness may occur after a filler treatment.

Blindness is a rare complication of dermal filler treatment. Unlike swelling and bruising, which are common, complication results from botched dermal treatment, especially on the face. Blindness happens when an aesthetic doctor injects the artery linked to the eyes. An aesthetic doctor should be familiar with muscles and blood vessels around the eye when injecting the fillers into the face. Understanding the anatomy of the face is key to the aesthetic doctor. With cosmetic treatment, patients may experience different types of blindness.

Secondary Visual Los for Filler Treatment 

Loh et al. (2016) stated that secondary visual loss resulting from filler treatment can occur in a rare form. Within seconds of the injection, the patient can have a visual loss. Depending on the muscle of the eye, visual loss may manifest some hours after the treatment blocking the posterior ciliary artery. As blindness, as mentioned above, is a rare complication from dermal fillers, some patients completely lose their vision. The loss of vision comes in stages accompanied by visual field defects. Visual loss after filler treatment is characterized by severe pain, ophthalmoplegia, and ptosis. The symptoms occur due to disturbed flow to the inferior and superior branches that supply the extraocular muscles. Dermal filler injections through the glabella and the nose pose a higher risk of blindness. Injection through the forehead and the cheeks poses a moderate risk of blindness. In contrast, the chins and eyelids are uncommon targets of adverse effects.

How Often Can Filler Cause Blindness?

Abduljabbar&Basendwh (2016) explained that filler treatments do not cause severe side effects. Hyaluronic acid filler can cause blindness in rare conditions and is accompanied by ptosis and severe pain. Blindness due to filler treatment is irreversible and has devastating effects.

Can Filler Result in Blurry Vision?

As aforementioned, wrongly done lip fillers can result in blurry vision in rare conditions. The blurry vision results from blockage of the ocular system responsible for focusing light into the back of the eye. The filler causes a refractive error in the eye, resulting in blurred vision. Patients with astigmatism, near-sightedness, and farsightedness, are predisposed to blur sight and blindness easily; they should avoid dermal fillers.

How Soon Does Vascular Occlusion Happen After Filler?

A patient can experience vascular occlusion about twenty-four hours after the filler treatment. The symptoms do not manifest immediately. It is hard to diagnose the case within a six-to-twelve-hour period as some aesthetic doctors and patients confuse it with a normal bruise. Eldweik (2021)stated that vascular ischemia comes out as a discoloration after the procedure and is easily noticeable. People should be keen even though these conditions rarely happen after the procedure. One can know that the filler treatment has resulted in vascular occlusion if the skin tissue color is changed and accompanied by severe pain.

How Soon Can Necrosis Happen After Filler Treatment?

According to Bravo et al. (2015), necrosis can happen some hours after the filler treatment has been conducted. The ischemia occurs earlier than the symptoms that occur later with time. A person can become affected before it is noticed; making this dangerous even though it rarely happens. For one to be diagnosed with such a defect, the skin color changes to blue and dark with some breakdown and pain.

Can Filler Cause Immediate Blindness?

The filler can lead to gradual blindness in rare cases through soft tissue treatment. The blindness is not instant as the filler affects the tissues around the eye, which with time, results in blindness. The injection can result in complications like pulmonary embolization and ischemia. 

Can Lip Filler Result in Blindness?

Fillers may cause blindness after some hours of the treatment procedure. The fillers block oscula muscles together with arterial vessels in an individual’s eye, making it hard for an individual to perceive an image.

Blindness is a rare complication of lip fillers. It is irreversible, although it occurs in rare cases. Blindness happens when the aesthetic doctor wrongly administers filler to certain risk areas. Therefore, patients should seek treatment from qualified practitioners who understand the anatomy of the human face and the effects of making the injection in some areas. The blindness may not manifest immediately after the injection; it could lead to irreversible effects when it occurs.
