Case Report: An Eyelid Nodule Caused by Candidatus Dirofilaria hongkongensis Diagnosed by Mitochondrial 12S rRNA Sequence.

A 59-year-old female living in Rayong Province, eastern Thailand, presented with painless, right upper eyelid nodule for 3 months. Upon removal of the eyelid mass, a well-circumscribed, firm globular mass with diameter about 1 cm was found. Histopathological examination revealed an immature female dirofilarial worm reminiscent of Dirofilaria repens, characterized by prominent sharp longitudinal ridges at external surface of the cuticle.

Factors Associated with Visual Outcome after Primary Repair of Open-Globe Injury by Ophthalmology Residents in Training in a Tertiary Eye Center.

Purpose: To assess factors associated with visual outcome after open-globe injury (OGI) repair by trainees.

Methods: In this observational study, charts of OGIs repaired by trainees at King Chulalongkorn Memorial Hospital, Chulalongkorn University, Bangkok were retrospectively reviewed. Preoperative, intraoperative, and postoperative outcomes (day 1, month 1, and month 6 postoperation) were analyzed.

Conjunctival sporotrichosis from cat to human: Case report.

Purpose: To report a case of conjunctival plaque infected from , which was possible transmitted from a cat.

Observations: A case of Thai woman presented with chronic painless ulcerated conjunctiva with white plaque. The lesion was not healed for one month after excision.

Orbital myeloid sarcoma in adult mimicking nasolacrimal duct obstruction: A case report.

Purpose: To describe an orbital myeloid sarcoma in adult presenting with a swollen mass at inferomedial canthal area and epiphora which was misdiagnosed as nasolacrimal duct obstruction.

Observations: A 45-year-old male presented with a swollen right lower eyelid around medial canthal area for 2 months with tearing for 6 month-period earlier. Eye examination demonstrated a high tear meniscus, slightly erythematous eyelid with palpable mass closed to the lacrimal sac along the inferior orbital rim.

Cytokeratin-Negative Undifferentiated (Lymphoepithelial) Carcinoma of the Lacrimal Sac.

Epstein-Barr virus-associated undifferentiated (lymphoepithelial) carcinoma is a malignancy that most commonly arises in the nasopharynx but can also occur in other locations including the lacrimal sac. Generally, this tumor strongly expresses cytokeratin, making the diagnosis straightforward. In the absence of confirmatory immunohistochemistry, the diagnosis can be problematic, particularly for tumors arising in unusual locations.

Case report of orbital cellulitis and necrotizing fasciitis from melioidosis.

A 48-year-old Thai male farmer presented with progressive swelling of the right eyelid and high-grade fever. His visual acuity declined and the right side of his forehead developed a necrotic skin lesion with a purulent discharge. CT of the orbits suggested orbital cellulitis with subperiosteal abscess.

Tarsal fracture operation in cicatricial entropion.

Background: Cicatricial entropion is a common eyelid condition encountered by ophthalmologists. There is a variety of procedures to correct this condition, in which tarsal fracture procedure is one of them. However, recurrence has been a problem and success rate should be calculated.

Efficacy of mitomycin C in endonasal endoscopic dacryocystorhinostomy.

Objectives/hypothesis: To evaluate the efficacy of intraoperative mitomycin C (MMC) in endonasal endoscopic dacryocystorhinostomy.

Study Design: Randomized controlled trial.

Methods: Fifty patients with primary acquired nasolacrimal duct obstruction were enrolled and randomly allocated into the treatment and control group.

Steatocystoma simplex of the eyelid.

A 47-year-old woman presented with a recurrent nodular lesion on the left upper eyelid that had been resected twice in the previous 5 years. Intraoperative findings showed a thin-walled cystic nodule containing a creamy substance. Histopathology identified steatocystoma; the diagnosis of steatocystoma simplex was further characterized by the absence of a family history and involvement of only one lesion.

Orbital metastasis of hepatocellular carcinoma.

We report a 74-year-old woman who presented with an orbital apex syndrome and pulsatile proptosis. CT showed a right orbital mass that destroyed the orbital sphenoid bone and extended intracranially. Biopsy revealed metastatic hepatocellular carcinoma (HCC), and subsequent investigations demonstrated a high level of serum-fetoprotein and a huge liver mass.

Multifocal squamous cell carcinoma of the conjunctiva with intraocular penetration in a patient with AIDS.

Purpose: To describe the clinical findings and to study the histopathology of conjunctival masses in a patient with HIV infection.

Methods: A case report.

Results: The histopathology from a 38-year-old Thai female patient who presented with visual loss on the left eye was studied.

Folliculectomy: management in segmental trichiasis and distichiasis.

Objective: To propose a new surgical technique as an alternative method for the correction of segmental trichiasis and distichiasis.

Material And Method: An interventional case series reviewed the segmental trichiasis and distichiasis patients who were treated with folliculectomy in the Ophthalmology Department, King Chulalongkorn Memorial Hospital. The data was collected from January 1997 to December 2002.

An unusual complication from esthetic injection of liquid silicone into the forehead.

Purpose: To report a case of migration of liquid silicone into the upper eyelid.

Design: Interventional case report.

Methods: A 32-year-old woman had an injection of liquid silicone into the subcutaneous tissue of the forehead.
