Benign & Malignant Skin Lesion
Surgical excision is recommended for malignant (cancerous) and certain benign (non-cancerous) skin lesions. In most cases, curettage is performed after the lesion is numbed via freezing or local anesthesia. A small amount of surrounding tissue is removed as well to ensure that all malignant cells are excised.
Pterygium is a benign growth of the conjunctiva (lining of the white part of the eye) that grows into the cornea, which covers the iris (colored part of the eye). A pterygium usually begins at the nasal side of the eye. It can be different colors, including red, pink, white, yellow, or gray.
Patients with pterygium often first notice the condition because of the appearance of a lesion on their eye or because of dry, itchy irritation, tearing or redness. Pterygium is usually first noticed when it is confined only to the conjunctiva. At this stage it is called a pingueculum. Once it extends to the cornea it is termed a pterygium and can eventually lead to impaired vision.
Chalazions (“small pimples” in Greek) are cysts, or fluid-filled sacs, on the edge of the eyelid. Small glands in the eyelids called meibomian glands normally secrete a thick, fatty fluid called sebum into the hair follicles of the eyelashes. When these glands become chronically inflamed, chalazions – also called meibomian cysts – form.
Our eyelids begin to stretch and sag as you grow older. In addition to age, there are other risk factors that may contribute to the sagging of eyelids, such as hereditary factors and sun exposure. The drooping is caused by muscles weakening and excess fat deposits gathering above and below your eyelids. As the eyelids droop they can form hoods and interfere with peripheral vision. To correct this problem, and restore proper vision, our ophthalmologist may recommend eyelid surgery.
You might consider blepharoplasty if droopy or sagging eyelids keep your eyes from opening completely or pull down your lower eyelids. Removing excess tissue from your upper eyelids, lower eyelids or both can improve vision and make your eyes appear younger and more alert. The surgery is minimally invasive and has a quick recovery time.
Ptosis is a condition in which the eyelid droops. It is caused by a weakness or separation of muscles deep within the eyelid. Ptosis does not involve excess skin or tissue in the eyelid (a condition called dermatochalasis). It is usually a result of aging, but some people develop ptosis after eye surgery or an injury. This procedure can be covered by medical insurance if it is visually significant. Dr. Nguyen can determine this by checking the peripheral visual field with an instrument called the Humphrey Visual Field (HVF) Analyzer. Patients who are also suffering from excess skin may choose to undergo blepharoplasty at the same time as ptosis repair. Please refer to Blepharoplasty above for more information.
