Blepharoplasty is determined based on clinical symptoms, as well as the results of slit lamp microscopy and ocular surface analyzer examination. Blepharosphenoid obstruction refers to the blockage of the opening of the blepharosphenoid glands, which is related to the fact that the secretion of the blepharosphenoid glands is too sticky and the washing of the face is too infrequent. 1. Clinical symptoms: Blepharosphenoid gland obstruction will result in the inability to discharge the secretions of the blepharosphenoid glands smoothly, and the patient will experience clinical symptoms such as dryness of the eyes, foreign body sensation, and tingling sensation. 2. Slit-lamp microscopy: When the doctor uses a slit-lamp microscope to magnify and observe, a semi-circular obstruction can be seen at the opening of the blepharoplasty gland. 3. Ocular surface analyzer examination: when doing an ocular surface analyzer examination, it can be seen that the blepharosphenoid glands have different degrees of atrophy, which is related to the function of the blepharosphenoid glands affected by the prolonged obstruction. When eye discomfort occurs, it is necessary to consult a doctor in a timely manner to confirm the diagnosis of blepharosphenoid gland obstruction and follow the doctor’s instructions for treatment.
