Case Report: A rare presentation and challenging reconstruction of an extensive cystic orbital schwannoma |
|
Son T Ho, Vikram Premkumar, Enrique Palacios, Alejandra A Valenzuela Pan Am J Ophthalmol 2013, 12:23 (1 January 2013)
A 57 year-old woman presented an irritated right eye and right-sided enophthalmos with hypoglobus for the past year. The patient previously had an extensive right-sided cystic orbital schwannoma removed with orbital reconstruction 5 years ago. Imaging revealed an enlarged right orbit with medial wall collapse and inferior displacement of a floor plate implant. An anterior orbitotomy with placement of an enophthalmos implant, three 1 mm Medpor sheets, an orbital rim implant, and an oral mucosa graft in inferior fornix with a lateral strip were used to reconstruct the ocular malposition and right lower lid retraction. We report a successful case of a complex orbital reconstruction in a patient with orbital deformity subsequent the removal of a massive cystic schwannoma.

Case Report: Unique finding of a fetal Rhabdomyoma in the lacrimal gland |
|
Alyssa E Sidoff, Son T Ho, Laura E Bratton, Alejandra A Valenzuela Pan Am J Ophthalmol 2013, 12:21 (1 January 2013)
Fetal rhabdomyoma is a rare neoplasm composed of immature striated muscle cells that resemble rhabdomesenchymal cells during weeks 6-10 of embryogenesis. This tumor, though well-described in many anatomic locations, is most commonly found in the head and neck region. We report a case which highlights the difficulty in diagnosing a fetal rhabdomyoma in the lacrimal gland of a 56 year old woman. This case report gives an overview of this rare neoplasm, detailing the presentation, diagnosis, and management.

Case Report: Retinal phototoxicity after macular hole surgery induced by xenon light: a case series |
|
Miriam García-Fernández, Joaquín Castro Navarro, Antonio Bajo Fuente Pan Am J Ophthalmol 2013, 12:17 (1 January 2013)
Retinal phototoxicity caused by light from endoilluminator used in vitrectomy has been described in the scientific literature. Xenon light can be one of the most harmful sources of radiation to the retina if adequate filters are not used as that radiation is near ultraviolet spectrum.
We present herein a case series of patients who developed retinal phototoxicity induced by xenon light, after macular hole surgery.
Macular phototoxic damage with foveal involvement remains a factual danger during vitrectomy using Xenon light as endoilluminator with inadequate filters.
