Dear Raja_Peter,Thank you for you question. A chalazion is a cyst in the eyelid that occurs due to a block oil gland. The chalazion itself causes swelling and the cyst can also exert pressure on the levator mechanism of the eyelid leading to ptosis (droopy eyelid). Treatment of the chalazion should be performed and the droopy eyelid should resolve after a few months. If there is persistent ptosis, the chalazion could have caused attenuation and weakening of the levator mechanism leading to permanent ptosis. If that is so, you may require ptosis correction surgery to treat it. Depending on the severity, different surgical options may be suitable for you. In Singapore, ptosis is considered a medical condition and you may be able to use your medisave for this condition. I would recommend seeking an in-person consultation with a board-certified plastic surgeon who has experience in blepharoplasty and ptosis repair surgery.I hope this answers your question. Have a great week ahead and all the best!Dr. Terence Goh Plastic Surgeon, SingaporeMBBS (S'pore), MRCS (Edinburgh), MMed (S’pore)Fellow, Academy of Medicine, Singapore (Plastic Surgery)President, Singapore Association of Plastic Surgeons (SAPS)International Member, American Society of Plastic Surgeons (ASPS)
