Notes: (A) Before the laser treatment: pigmented nevus located at the upper and lower eyelid margins of the left eye, adjacent to the lacrimal punctum and extending to the eyelid conjunctiva. (B) One month after the seventh laser treatment: evidence of partial sparse eyelashes, absence of lesion recurrence, no scar hyperplasia, and a smooth eyelid margin without signs of entropion or ectropion. (C) Pathological diagnosis: pigmented nevus OS. Pathological findings: scattered nevus cells beneath the stratified squamous epithelium, with preserved cellular polarity and no discernible cellular atypia. (HE staining, ×200)

Figure 2 Pigmented nevus (OS) before and after laser treatment and pathological examination in a 25-year-old male
Notes: (A) Before the laser treatment: a black lesion grew along the eyelid margin on the lateral side of the lower eyelid, about 12 mm×5 mm in size, with a clear boundary, involving the root of eyelashes and conjunctiva. (B) One month after the fourth laser treatment: absence of lesion recurrence, no scar hyperplasia, a smooth eyelid margin without signs of entropion or ectropion, and partial sparse eyelashes in the treatment area. (C) Pathological diagnosis: pigmented nevus OS. Pathological findings: scattered nevus cells beneath the stratified squamous epithelium, with preserved cellular polarity and no discernible cellular atypia. (HE staining, ×200)

Figue 3 Xanthelasma (OU) before and after laser treatment in a 48-year-old female
Notes: (A1 & A2) Before the laser treatment: there were flat yellow lesions on the inner side of the upper eyelid of both eyes with clear edges. The size of the lesions in the right eye was about 10 mm× 6 mm, and that in the left eye was about 15 mm× 6mm. (B1 & B2) One month after the fifth laser treatment: there was no lesion recurrence, minimal scar hyperplasia and pigmentation.

Figure 4 Eyelid molluscum (OS) before and after laser treatment and pathological examination in an 18-year-old male
(A) Before the laser treatment: a dense granular lesion extending vertically from the eyelid margin to the eyebrow root, ranging about 8 mm×20 mm. (B) One month after the third laser treatment: no evidence of lesion recurrence, scar hyperplasia, or trichiasis. (C) Pathological diagnosis: eyelid molluscum OS. Pathological findings: proliferative and degenerative changes in the stratified squamous epithelium. The epithelium showed incomplete keratinization alongside hyperkeratosis. (HE staining, ×200)

Figure 5 Malignant melanoma (OD) of the eyelid before and after laser treatment and pathological examination in a 48-year-old female
(A) Before the laser treatment: black lesion located at the root of the eyelashes of the lower eyelid, about 2 mm×2 mm in size, and not involved gray line. (B) One-month post-laser treatment: no recurrence of the lesion, no evidence of scar hyperplasia, no signs of entropion or ectropion, and partial sparse eyelashes in the treated area. (C) Pathological diagnosis (HE staining, ×200): malignant melanoma OD. (D) One-month after laser treatment: a controlled surgical excision of the lesion area was performed. Histological examination revealed fibrous tissue proliferation and degeneration, with minimal lymphocytic infiltration and no evident tumor tissue. (HE staining, ×200)
