Giant myofibroma of the orbit in an adult male.

A 47-year-old male with history of schizophrenia developed painful proptosis and vision loss. Computed Tomography revealed a bone-destructive mass with encroachment on the orbit and compression of the right eye. Superolateral orbitotomy and biopsy revealed a lesion composed of a mixture of spindled and epithelioid cells without significant cytologic atypia or mitotic rate. Immunohistochemical stains were positive for vimentin and multifocally for smooth muscle actin, supporting the diagnosis of orbital myofibroma. Although orbital myofibromas typically present during childhood, they may occur in older patients and act as an expanding mass causing compression of adjacent structures.

Effects of common topical antiglaucoma medications on the ocular surface, eyelids and periorbital tissue.

Glaucoma affects millions of people around the world. With the baby boom generation aging, the number of people affected by primary open-angle glaucoma in the US is expected to reach 3.3 million by 2020, and about half may not know they have the disease. The treatment of most forms of glaucoma includes the use of topical agents that enhance aqueous humour outflow, reduce aqueous production, or both. Topical intraocular pressure-lowering drugs must penetrate across the tissues of the eye to reach their therapeutic targets. Often, these tissues show the first signs and symptoms of drug toxicity and adverse effects. These include eyelid dermatitis, malpositions, lacrimal system scarring, ocular discomfort upon instillation, tear film instability, conjunctival inflammation, subconjunctival fibrosis, conjunctival epithelium changes, and corneal surface and endothelial impairment. For these reasons, ophthalmologists should evaluate the risks and benefits of ophthalmic medications before initiating therapy, identify the minimum dosages necessary to achieve a therapeutic benefit, and monitor patients for local and systemic adverse effects. Adverse events may be reduced by changing to a different class of topical medication, using corticosteroids, lubricating the eyes frequently, and reducing exposure to preservatives. This in turn can lead to higher levels of adherence to antiglaucoma therapy, improved outcomes and a reduction in the costs associated with long-term glaucoma complications. This article reviews the ocular adverse effects associated with the various classes of topical antiglaucoma drugs, with a particular focus on the ocular surface, eyelids and periorbital tissue.

Mucoepidermoid carcinoma of the lacrimal sac after dacryocystectomy for squamous papilloma.

A mass that recurred after dacryocystectomy for benign squamous papilloma of the lacrimal sac was diagnosed as a high-grade mucoepidermoid carcinoma in a 53-year-old man on histopathology. Local excision to the orbital periosteum was performed and gave a margin free of invasion. Neither local recurrence nor systemic metastasis was found 3 years after local excision. Mucoepidermoid carcinoma of the lacrimal sac is extremely rare and spreads locally in an aggressive manner; a cure typically requires exenteration, radical resection, or adjuvant radiotherapy. In this rare case, despite the high malignancy, the patient underwent successful local excision, achieved an aesthetically satisfying result, and has had a long-term cancer-free period.

Congenital anophthalmia: a review of dealing with volume.

BACKGROUND: Anophthalmia in childhood whether congenital or acquired is not just a question of cosmesis. Loss of an eye can effect the maturation of the soft tissues and bony structure surrounding the affected orbit. Therefore, a comprehensive approach including medical and surgical interventions is required to rehabilitate a child early in life. MATERIALS AND METHODS: A literature survey of the past 40 years on the topic of congenital anophthalmia with focus on medical and surgical volume augmentation of the orbit was conducted. RESULTS: Newer technologies including hydrogel implants and saline-filled tissue expanders have allowed for more rapid expansion of the pediatric orbit often with minimally invasive surgical procedures. However, traditional approaches including conformer therapy are still the primary intervention in these complicated cases. CONCLUSION: Anophthalmia in childhood requires a close interaction between ophthalmologist and ocularist as well as a motivated patient and family. With early intervention a good cosmetic outcome with periocular symmetry is obtainable.

Multiple pilomatrixoma in Turner syndrome.

Pilomatrixoma is typically an isolated benign tumor of the hair follicle matrix with very low recurrence rates. The authors report a case of multiple pilomatrixoma in a patient with Turner syndrome. The patient was a 13-year-old girl with a history, to date, of 10 separate facial lesions, manifesting over the course of 7 years, and confirmed by histopathology as pilomatrixoma. The presence of multiple pilomatrixoma in a patient raises the suspicion of Turner syndrome.

Oculocerebrocutaneous syndrome: a case report.

There are many congenital ocular malformations associated with systemic findings. In cases such as oculocerebrocutaneous syndrome, the severity of systemic findings makes diagnosis particularly important. This case report presents a case of this uncommon syndrome and demonstrates the common findings.

Carcinosarcoma of the orbit: report of two cases and review of the literature.

OBJECTIVE: To report the clinicopathologic features of 2 patients with carcinosarcoma of the orbit. DESIGN: Case reports. PARTICIPANTS: Two patients with orbital carcinosarcoma were identified. METHODS: Retrospective chart review with clinicopathologic correlation and literature review. MAIN OUTCOME MEASURES: Clinical examination, imaging studies, and histopathologic findings. RESULTS: Two patients, a 56-year-old woman and a 91-year-old woman, with orbital carcinosarcoma were identified. Both tumors contained sarcomatous and carcinomatous components and invaded periorbital structures. CONCLUSIONS: Carcinosarcoma may arise in the orbit or extend into the orbit from the paranasal sinuses. This malignant neoplasm should be aggressively treated with a combination of surgical resection, chemotherapy, and radiation therapy.

Inverted papilloma of the nasolacrimal system invading the orbit.

A 73-year-old man with a history of epiphora, discharge from the left eye, and left-sided nasal congestion underwent external dacryocystorhinostomy for nasolacrimal duct obstruction. The procedure revealed bony erosion of the majority of the lacrimal sac fossa and a large papillomatous mass filling the lacrimal sac and nasolacrimal duct. Inverted papilloma was diagnosed via biopsy. A subsequent orbitotomy with combined endoscopic medial maxillectomy was performed to remove the mass. This case illustrates the importance of including inverted papilloma, a benign but invasive neoplasm, in the differential diagnosis of nasolacrimal duct obstruction.

Orbital complications of hydrogel scleral buckles.

PURPOSE: Hydrogel is a biocompatible osmotic expansile material used in contact lenses, scleral buckles, and orbital expanders. Three unique complications from hydrogel scleral buckle use are presented: orbital cellulitis mimicry, fornical shortening with orbital prosthetic intolerance, and orbital pseudotumor. METHODS: A retrospective chart review was conducted on three subjects with unknown hydrogel scleral buckle complications at a tertiary care oculoplastics practice. Demographics, imaging studies, and pathologic specimens were reviewed. RESULTS: All three patients had a history of encircling hydrogel scleral buckle placed for retinal detachment. The mean time from implantation to presentation was 10.7 years (range, 7 to 15 years). One patient had an onset of presumed orbital cellulitis caused by an enlarged buckle and no abscess. The second patient had inability to wear an evisceration prosthesis as the result of a shortened fornix from an enlarged hydrogel scleral buckle implant. The third patient presented with an orbital mass caused by the enlarged implant. In all cases, surgical removal of the expanded buckle relieved the patient's symptoms. CONCLUSIONS: Although the hydrogel scleral band is designed to expand in a controlled fashion, overexpansion can occur. Expansion can cause buckle extrusion, prosthetic intolerance, a pseudo-orbital cellulitis, or orbital pseudotumor and may be due to a chemical change in the hydrogel polymer. Patients with hydrogel scleral buckles should be followed long-term for possible complications. Patients with newer uses of hydrogel, such as orbital expanders, should also be observed for long-term complications.
