The loss of an eye due to occupational injury: Two case studies of ocular prosthetic rehabilitation

BACKGROUND: Two patients received ocular injuries from rusted metallic projectiles at their industrial workplaces. Said injuries resulted in the loss of their eyes by evisceration surgeries to prevent fatal infections. CASE DESCRIPTION: The first case, a man in his twenties, received a stock conformer immediately after surgery and started prosthetic therapy within 2 months. The second case, a man in his forties, started prosthetic therapy after 10 years. Definitive custom ocular prostheses were fabricated and relined according to conventional protocol. RESULTS: On issue of the prosthesis, there was adequate retention, aesthetics and stability to extra-ocular movements and treatment was considered successful for both cases. However, follow-ups showed noticeable prosthetic eye movements for case 1 which, to some extent mimicked the physiologic movement of its fellow natural eye. Case 1 adjusted to his prosthesis better while case 2 was still adjusting with little to no physiologic movement. CONCLUSION: Prosthetic rehabilitation should be started as early as possible to obtain optimum rehabilitative results.

Outcomes of secondary autologus dermo-fat orbital implants in anophthalmic sockets

Objectives: To evaluate the outcomes of secondary autologous dermis-fat graft as an orbital implant in anophthalmic sockets. Methods: In this prospective study, which was conducted at Jinnah Post Graduate Medical Centre, Karachi, between January 2015 and January 2020, we evaluated 12 patients between the ages of four and 60 years. Most of the adults were victims of trauma, whereas children were known cases of retinoblastoma or trauma and all underwent enucleation. All of them were primarily treated elsewhere and not offered primary orbital implants. We performed autologous dermis-fat graft as an orbital implant in these patients harvesting graft from gluteal region and followed them up to look for complications. Results: Out of 12 patients two went into failure, while rest of the patients showed successful outcome. All patients underwent successful surgery. Initially, a silicon conformer was placed, which was later on replaced with artificial prosthetic eye. Conclusion: Regardless of the small sample size, this procedure proved to be a safe and effective method for augmenting orbital volume in anophthalmic sockets in children and adults. doi: https://doi.org/10.12669/pjms.37.2.3209 How to cite this:Hayat N, Jan S, Atiq N, Cheema A.

The importance of reestablishing orbitary architecture for rehabilitation with an ocular prosthesis: a case report

Anophthalmia is mainly caused by two etiological groups, trauma and medical conditions. In addition, anophthalmia creates difficulties in social, professional, and family adaptation due to psychological, and functional disorders related to eye loss. Studies show a positive influence on the personal relationship of patients with anophthalmia after being rehabilitated with ocular prostheses. However, in order to achieve a good aesthetic result in prosthetic eye rehabilitation, it is essential that the size and positioning of the orbital skeleton are adequate. Facial trauma can also cause defects associated with bone loss, and in these cases, reconstructive techniques aim to restore the appropriate bone contour. The aim of this work is to report a case where reconstructive treatment was performed on a patient victim of a long-term traffic accident sequel, using an alloplastic implant in polymethylmethacrylate (PMMA) and bone repositioning, so that an ocular prosthesis could be made. At the end of the treatment, after reconstruction of the frontal-nasal region in PMMA and repositioning of the left zygoma, the aesthetic objectives were achieved and the patient improved his self-esteem and social life.

FABRICATION OF OCULAR PROSTHESIS - A COMBINATION OF A STOCK AND CUSTOM MADE PROSTHESIS- A CASE REPORT

An ocular defect may affect a patient psychologically and an ocular prosthesis is given to uplift the patient psychologically and improve the confidence. Defects of the eye may follow the removal of a part of or the entire orbit. This results in the patient becoming visually and psychologically handicapped. Restoring the defect with a prosthesis not only restores esthetics but also gives back the lost confidence to the patient. This is a case report of a patient with a prosthetic eye fabricated by the combination of a stock eye and a custom ocular prosthesis.
