Children recurrent chalazion, children multiple chalazion, is troubled our pediatric ophthalmologist a piece of heartache, this kind of cases, we used to only surgical treatment, parents are particularly not easy to accept, 16 years ago I have been trying to do this project, has not found a good entry. We recently introduced the EOS ultra-pulsed light treatment for children with chalazion, this project in the country, the international treatment is currently very few doctors, we are in the clinical side of the fumble, while treatment, the 9th batch of children have returned to treatment, the effect is still relatively satisfactory. The most one child has about 12 chalazia in both eyes, and 2 huge chalazia are about to break out of the skin surface, the strong pulse light treatment twice, basically the chalazia disappeared and shrunk. Many parents are concerned about what this intense pulsed light is for. In fact, this pulsed light program is currently the best treatment program for girls to do skin rejuvenation, wrinkle removal, and facial beauty, and we are using the concept of medical beauty, normal and reasonable use is very safe. Each child has about 25-30 blepharoplasties in one eyelid. Looking at these photos again, if this chalazion surgery is done it will certainly destroy at least 7 to 40 lid glands. This is because the tear production when the child is small. Lid fat secretion are more vigorous, there will be no dry eye symptoms after the surgery. After middle age, with the different degree of destruction of the lid glands, the dry eye symptoms must show up. In many children, recurrent chalazion is caused by the dysfunction of the lid glands. Normally, children’s lid glands secrete a lipid, which is commonly known as a very thin, slippery oil. As a result, the sebaceous glands and the lid glands collect more and more sebum, which eventually turns into a destructive “necrotic material” like tofu crumbs. Chalazion is an idiopathic chronic non-purulent inflammation of the lid gland that causes a small bump on the child’s eyelid early in life, and later the skin is perforated, and after the perforation, the inflammation combined with scarring results in a very unsightly scar on the skin, even disfiguring. We usually operate on children only to remove this necrotic tissue and stitch up the skin, but the inflammation and swelling of the lid gland tissue remains unrelieved and is therefore very recurrent. I have performed up to 8 chalazion surgeries on one child, and the key is that each surgery needs to be achieved under general anesthesia, which is painful for the mother. We have a new program for the treatment of recurrent childhood chalazion with the Intense Pulse Laser. I. The photothermal effect of the pulsed laser breaks up the coagulated lid fat, softening the sticky lid fat for easy discharge. Second, it can also remove cystic granulation tissue . The cyst is gradually reduced in size, absorbed and dissipated. This allows the cyst to shrink, absorb and dissipate. It also closes the dilated capillaries of the lid margin to reduce the release of local inflammatory factors and decrease the bacterial load of the lid margin and surrounding appendages. Fourth, the mite killing effect is remarkable, and with eyelash plucking, there is no need for electron microscopy of mites. This new technique effectively reduces dry eyes improves the normal secretion function of the lid gland and can relieve, improve, and treat recurrent chalazia in children, and many children can avoid surgery. Now when doing chalazion in children, the other parts of the 4 eyelids are treated with intense pulsed light at the same time so that recurrent post-operative recurrence is avoided.
