Malignant oncocytoma of the lacrimal sac as an unusual cause of epiphora.

A 72-year-old man presented with a 2-year history of epiphora. CT revealed an extensive inferomedial orbital tumor connected to the lacrimal sac and duct. Incisional biopsy revealed malignant oncocytoma of the lacrimal sac.

Detection of Chlamydia pneumoniae in a bilateral orbital mucosa-associated lymphoid tissue lymphoma.

Purpose: To detect Chlamydia pneumoniae (C. pneumoniae) gene in a patient with bilateral orbital musoca-associated lymphoid tissue (MALT) lymphoma.

Design: Interventional case report.

Encapsulated triamcinolone cyst after subtenon injection.

The authors report the formation of a subtenon cyst following subtenon triamcinolone injection for chronic recurrent uveitis in Behçet's disease. The steroid was inadvertently placed superficially in the anterior subtenon space and was encapsulated eventually to present as a subtenon cyst. The episode of uveitis recurrence, which did not regress, required treatment with a repeat posterior subtenon injection 2 months later.

Multiple eyelid defects in cutaneous Langerhans cell histiocytosis.

Langerhans cell histiocytosis is a disorder characterized by the proliferation of histiocytes of the mononuclear phagocyte system. Cutaneous Langerhans cell histiocytosis can develop as a solitary lesion or more frequently as part of a multisystem disease. This report describes a case of cutaneous Langerhans cell histiocytosis affecting the eyelids, resulting in a coloboma-like defect.

Cholesteatoma palpebrae: an unusual cholesterol-filled cyst in the eyelid.

Cholesteatomas, also known as epidermal cholesterol cysts, are unusual cystic lesions containing numerous cholesterol clefts that are usually found in the orbits in the ophthalmic setting. This report describes the clinical and microscopic features of an unusual cholesteatoma in the eyelid.

Atypical presentation of Rosai-Dorfman disease in the lacrimal gland mimicking malignancy.

A 29-year-old man presented with a painful, rapidly growing mass in the right upper eyelid. Ophthalmic and systemic examinations and results of laboratory investigations were all normal. CT revealed a mass in the right lacrimal region with surrounding bone destruction, which was suggestive of a malignant lacrimal gland tumor.

Ocular manifestations and surgical management of lid coloboma in a Chinese infant with linear nevus sebaceous syndrome.

An 8-month-old Chinese girl with linear nevus sebaceous syndrome had a right upper lid coloboma and right superior scleral ectasia. At 20 months old, successful surgical repair of the lid coloboma was performed with particular attention paid to the sclera ectasia.

Indocyanine green-assisted internal limiting membrane removal in epiretinal membrane surgery: a clinical and histologic study.

Purpose: To evaluate the clinical outcome and quantify histologically the amount of microscopic internal limiting membrane (ILM) and epiretinal membrane (ERM) present in ILM and ERM specimens obtained from ERM surgery.

Design: Interventional consecutive case series.

Methods: Patients scheduled for ERM surgery were recruited prospectively.

Modified lateral orbitotomy for intact removal of orbital dumbbell dermoid cyst.

: We describe a modified lateral orbitotomy for intact removal of a dumbbell dermoid cyst involving the frontozygomatic suture. The clinical features and surgical treatment of the case are discussed.

Epiretinal membrane formation with internal limiting membrane wrinkling after Nd:YAG laser membranotomy in valsalva retinopathy.

Purpose: To report the location of premacular hemorrhage in Valsalva retinopathy and epiretinal membrane formation with internal limiting membrane (ILM) wrinkling after neodymium;yttrium-aluminum-garnet (Nd:YAG) laser membranotomy.

Design: Interventional case report.

Methods: A 35-year-old man with a massive premacular hemorrhage due to Valsalva retinopathy underwent Nd:YAG laser membranotomy.

Isolated microspherophakia with optic disc colobomata.

We describe a case of isolated bilateral microspherophakia with optic disc colobomata. A satisfactory outcome was achieved following uneventful lensectomy and scleral fixation of an intraocular lens.

The use of postoperative topical mitomycin C in the treatment of recurrent conjunctival papilloma.

Purpose: To describe the use of postoperative topical mitomycin C (MMC) in the treatment of recurrent conjunctival papilloma.

Methods: Case report.

Results: We report a 26-year-old man with recurrent conjunctival papilloma despite repeated surgical excision, cauterization, and cryotherapy.
