Use of x-ray film implant for the repair of orbital fractures.

PURPOSE: To evaluate the experience with sterilized x-ray film in the repair of orbital blow-out fractures (BOFs). METHODS: A retrospective review of case notes from 56 patients with orbital BOF repaired using sterilized x-ray film onlay implants at 2 institutions between November 2004 and December 2010. Patient demographics, timing of surgery, surgical approach, postoperative complications, and length of follow up were recorded. RESULTS: Fifty-six patients (44 men, 12 women) received sterilized x-ray film implants during the 6-year study period. Mean age at the time of repair was 29 years (range 4-85 years). For 68% of patients, surgical repair was performed within 2 weeks of injury. Average length of postoperative follow up was 5.5 months (range 1-36 months), 48% had follow up >3 months. Following surgical repair, diplopia in primary or down gaze reduced from 98% to 4% and enophthalmos ≥2 mm reduced from 21% to 5% cases. One patient required a second operation for repositioning of an incompletely reduced fracture. A second patient presented 9 months postoperatively with recurrent episodes of proptosis, and the implant and its surrounding pseudocapsule were subsequently removed. There were no cases of visual loss, implant infection, or migration. CONCLUSIONS: This series has demonstrated that in selected orbital fractures sterilized x-ray film can provide a safe, effective, and low-cost onlay implant.

A proposed model of the response of the anophthalmic socket to prosthetic eye wear and its application to the management of mucoid discharge.

Mucoid discharge associated with prosthetic eye wear can be a distressing condition that affects the quality of life of people who have lost an eye. Discharge is the second highest concern of experienced prosthetic eye wearers after health of the companion eye and is prevalent in anophthalmic populations. Specific causes of mucoid discharge such as infections and environmental allergens are well understood, but non-specific causes are unknown and an evidence based protocol for managing non-specific discharge is lacking. Current management is based on prosthesis removal and cleaning, and professional re-polishing of the prosthesis. Tear protein deposits accumulate on prosthetic eyes. These deposits mediate the response of the socket to prosthetic eye wear and their influence (good and bad) is determined by differing cleaning regimes and standards of surface finish. This paper proposes a three-phase model that describes the response of the socket to prosthetic eye wear. The phases are: An initial period of wear of a new (or newly-polished) prosthesis when homeostasis is being established (or re-established) within the socket; a second period (equilibrium phase) where beneficial surface deposits have built up on the prosthesis and wear is safe and comfortable, and a third period (breakdown phase) where there is an increasing likelihood of harm from continued wear. The proposed model provides a rationale for a personal cleaning regime to manage non-specific mucoid discharge. Professional care of prosthetic eyes is also important for the management of discharge and evidence for effective surface finishing is reported in this study. Taken together, the proposed regimes for personal and professional care comprise a protocol for managing discharge associated with prosthetic eye wear. The protocol describes prosthetic eye cleaning methods and frequency, and suggests minimum standards for professional polishing. If confirmed, the protocol has the potential to resolve the current varied and contradictory opinions about the management of discharge, and to clarify advice given to patients about how to personally care for their prosthetic eyes.

Castleman's disease of the lacrimal gland.

Castleman's disease, also known as angiofollicular lymphoid hyperplasia, is a lymphoproliferative disorder that is generally benign. The lesions most commonly originate in the lymph nodes of the mediastinum. The second documented case of Castleman's disease of the lacrimal gland is reported in an 84-year-old woman who presented with an 8-year history of a left upper lid mass. This was excised via a lateral orbitotomy, and a diagnosis of Castleman's disease was made histologically. Relevant images of the clinical findings and histology are shown.
