The lateral component of the orbitomalar ligament provides major osteocutaneous midfacial support. Subcutaneous attenuation of the orbitomalar, masseteric cutaneous, and zygomatic ligaments was associated with midfacial ptosis.

To determine a classification system for epiblepharon of the lower eyelid and to evaluate a possible correlation between lower lid epiblepharon and astigmatism. Three morphologic characteristics (skin fold, cilia touching the cornea and corneal erosion) were observed by slit-lamp biomicroscopic examination and Polaroid pictures in 186 eyes of 102 patients with epiblepharon of the lower lid. In 112 eyes, cycloplegic refractions performed. A classification system reflecting the severity of epiblep

This retrospective study was launched to evaluate the efficacy of doxycycline and to find independent predictors of a clinical response in patients with ocular adnexal lymphoma of mucosa-associated lymphoid tissue (OAML). Thirty-eight patients with newly diagnosed, localized OAML received doxycycline for 3 weeks (12 patients) or 6 weeks (26 patients). Clinical factors including absolute lymphocyte count (ALC) and neutrophil count (ANC) were compared between responders and non-responders. After a

Transplanting biomaterial-free COMECs seems to be an efficient and safe procedure to reconstruct the ocular surface in patients who are completely limbal stem cell deficient without a full symblepharon.

This surgical technique is effective for the correction of epiblepharon, and it is easy to determine the amount of excision. Using this technique, a 1 mm to 3 mm width of excision is sufficient.

The ancient schwannoma is a rare variant of a neurilemoma with a course typical of a slow-growing benign neoplasm. Histologically, it can be confused with a malignant mesenchymal tumor because of increased cellularity, nuclear pleomorphism, and hyperchromatism. Despite the degree of nuclear atypia, mitotic figures are absent. We describe the clinical and histopathologic features of an ancient schwannoma of the orbit.

The group with metastasis showed higher expression levels of Shh, ABCG2, and Wnt than did the group without metastasis, and patients with strong ABCG2 expression, Wnt, or LRP expression showed higher cumulative incidence of lymph node or distant metastasis, implying that activation of the Shh and Wnt signaling pathway is associated with aggressive behavior of the tumor.

With eyelid closure, the canalicular system contracts, and the superior portion of the lacrimal sac dilates; these may be important parts of the active lacrimal pump mechanism. These findings suggested that the canalicular system and the superior portion of the lacrimal sac play key roles in active tear drainage pump.

Partial mass (visible part only) excision, including that of the overlying thick conjunctiva, and free conjunctival autograft from the opposite eye, is a relatively simple and effective technique for the surgical management of conjunctival dermolipoma.

A 37-year-old woman presented with a 2-month history of fullness and ptosis of the left upper eyelid. Examination revealed a 6-cm x 2-cm mass in the left brow and upper eyelid, and a diffuse mass in the lower eyelid. Marked ptosis of the left upper eyelid and elevation of the left lower eyelid were noted. CT showed masses with a bone-like density in the left eyelid and periorbital soft tissue. A through history revealed that the patient had received calcium hydroxylapatite filler injection for n
