The prosthetic rehabilitation of a large anophthalmic socket is always a challenge. It demands an equally sized ocular prosthesis to replace lost tissue volume. A conventional solid acrylic ocular prosthesis may be deterrent to retention and esthetics because of its weight, which can be reduced by eliminating the mass of material within it. This article attempts to present a simplified and accurate technique to fabricate a hollow ocular prosthesis using silicone putty cavity form. It is removed prior to final processing and serves to ensure appropriate uniform thickness of acrylic resin and optimal weight reduction of the definitive prosthesis without compromising mobility, esthetics, and structural integrity...

Current approaches to orbit reconstruction are based on the assumption of facial symmetry and surgeons' experiences, and the reconstructed orbits are not precise. Through computer-assisted volumetric quantitative analysis, the volume of the bony orbit, and the volume of the soft tissues in both the anophthalmic orbit and the contralateral orbit are calculated in 39 anophthalmic patients. The rib graft is used for orbit reconstruction; the dosalis pedis flap and lipo-injection were used for soft tissue reconstruction and skin socket reconstruction...

Reconstruction of the anophthalmic socket allows the use of an ocular prosthesis and rehabilitation of facial appearance. Dermis-fat grafting is one option in volume augmentation of the anophthalmic socket and presents unique benefits, including increased surface area within the socket and the ability to grow with pediatric patients. Postoperative complications of this procedure are relatively common. Minor complications, such as graft hirsutism, keratinization, and conjunctival cysts or granulomas, are managed easily by observation or simple intervention...

Anophthalmic socket cysts are challenging to remove and incomplete excision has been shown to increase the risk of recurrence. This case series describes a novel technique utilising the fibrin sealant Tisseel (Baxter AG, Vienna, Austria) to retain the socket cyst integrity during surgical removal to facilitate its complete excision. Five patients were included and followed up for a minimum of 1 year, and there were no signs of recurrence in any of the cases. The surgical technique is described and illustrated...

This clinical report describes the ocular rehabilitation of a child, initially using an acrylic expander and subsequently the conventional prosthesis. A two-month-old anophthalmic female patient was referred to Araçatuba Dental School, for rehabilitation with ocular prosthesis. The treatment chosen was the manufacturing of expander prostheses changed periodically until the socket reached an adequate size, so that a definitive ocular prosthesis could be installed. The acrylic expander remained in patient's anophthalmic socket for 60 days in order to restore its volume...

We present the case of a 56-year-old man who developed a neoplasm of epithelioid histology in his anophthalmic left orbit 21 years after he underwent enucleation for a spindle cell iris melanoma. The recurrent tumour was managed by orbital exenteration. Neither further recurrence nor metastasis was diagnosed over a 5-year follow-up period. This case, along with five other similar cases in the literature,(1-3) emphasises the importance of long-term follow-up after treatment of iris melanoma.

Traumatic globe dislocation into the maxillary sinus is a rare event and usually associated with a poor visual outcome if not managed appropriately. We report a 45-year-old female patient who presented to the emergency after blunt injury to her face with a door. Initial evaluation revealed nil perception of light and an apparently anophthalmic socket. Neuroimaging revealed large floor and medial wall fracture with dislocation of the globe into the maxillary sinus. The patient underwent exploration with repositioning of the globe and fracture repair...

V Bosch-Canto, C Cruz, J C Ordaz-Favila
Retinoblastoma is the most frequent intraocular tumour in childhood. The definitive treatment is enucleation. The management of the anophthalmic socket consists in the use of a plastic implant. The problem is that they are expensive and they usually extrude. The use of dermal-fat grafts minimises the hemi-facial hypoplasia. They usually grow with the face, and help to expand the orbital bones, thus avoiding the psychological and physical consequences. OBJECTIVE: To determine if there is hemi-facial hypoplasia, using MRI images after the use of a dermal-fat implant in patients enucleated for RB...

We report the first description of oculocardiac reflex elicited with injection of local anesthetic in an empty orbit, and highlight clinical indicators for patients that may be at risk for an exaggerated oculocardiac reflex. We describe a patient with prior head and eye trauma treated for anophthalmic socket reconstruction at an outpatient eye surgery center. Injection of local anesthetic into the empty orbit induced an extended sinus arrest. This exaggerated response was avoided in a subsequent surgery by pretreatment with high-dose anticholinergics...
