The article focuses on a study by authors on anophthalmic socket and use of orbital implants to restore the lost volume after enucleation. It is mentioned that anophthalmic socket occurs when there is congenital conditions that causes no development of optic vesicle. Symptoms' of the disease include secretion, pain, eyelid retraction and loss of orbital volume. After enucleation, cavity is replaced by using orbital implants which are coated to reduce exposure.

- Abstract
Objective: Ocular changes in special due to volume loss in eviscerated cavities promote several psychological aesthetic and functional alterations to patients. For this reason, searches aiming at finding a material of low cost and biocompatibility have been constantly carried out. Test experimentally the implants constituted of ultra-high molecular weight granular polyethylene of low cost, in orbits of rabbits subjected to surgical evisceration in several experimental times, evaluating the macro and microscope aspects besides the systemic toxicity of the material. Methods: In this study we eviscerated the right ocular globe of rabbits of the species Oryctolaguscuniculus, implanted posteriorly a sphere of granular polyethylene of ultrahigh molecular weight and analysed the effects through macro, micro and biochemical parameters during 15, 30, 90 and 180 days after implantation. The control group were submitted the same procedure without the implants. Results: This paper shows that the material used in the cavity does not present significant alteration in the weight and in the biochemistry of the animal; a good assimilation (integration) of the material implanted by the tissue formed was observed inside the implant. Conclusion: The results indicate that ultra-high molecular weight granular polyethylene implant developed by a national industry presents excellent integration in the model used supporting further use in tests with humans.

Made available in DSpace on 2018-11-26T17:55:20Z (GMT). No. of bitstreams: 0 Previous issue date: 2018-09-01 Purpose: To evaluate the outcomes of dermis-fat graft procedure for orbital volume replacement in anophthalmic socket. Methods: A retrospective chart review was performed studying all dermis-fat graft surgeries done at King Khlaed Eye Specialist Hospital in the last 10-year period. Sixty-two anophthalmic socket carriers underwent dermis-fat graft during the study period. Data were collected on characteristics of the patients, postoperative complications, cosmesis, and functional results such as the ability to hold an external prosthesis. Results: Mean age of the patients included in the study was 34.2 +/- 9.7 years. There were 38.7% of patients with grade 3 anophthalmic socket, 64.5% of patients had an acquired anophthalmic socket, and dermis-fat graft was performed as a secondary procedure in 61.3% of patients. Postoperative complications included lagophthalmos (22.6%), graft necrosis (17.7%), pyogenic granuloma (12.9%), decreased graft size (12.9%), malpositioned lids (3.2%), and volume deficiency (3.2%). The prosthesis was held in place in 49 patients (79%) preoperatively and in 55 patients (88.7%) postoperatively. Conclusion: Dermis-fat graft is an excellent option for congenital or acquired as well as primary or secondary anophthalmic sockets, with or without contraction. The outcomes are favorable, and complications are rare.

This literature review considers the treatment of an anophthalmic socket and the controversial aspects of the implants used to restore the lost volume after enucleation or evisceration, including the different materials employed and the main problems encountered during anophthalmic socket reconstruction. Since the 1980s, when integrated implants were proposed, there has been much controversy about what is the best implant for restoring the lost volume in an anophthalmic socket: integrated or non-integrated implants. Thus, we present this literature review to provide guidance to doctors and consumers RESUMOEsta revisão da literatura abrange o tratamento da cavidade anoftálmica, assim como os controversos aspectos relacionados com os implantes de cavidade utilizados para recompor o volume perdido após enucleações ou eviscerações, tais como os diferentes materiais utilizados e os principais problemas enfrentados na reconstrução da cavidade anoftálmica. Depois dos anos 80 do século passado, quando foram introduzidos os implantes integrados, há muitas controvérsias sobre qual seria o melhor implante para recompor o volume perdido na cavidade anoftálmica: implante integrado ou não integrado? Desta forma, apresentamos esta revisão da literatura, que procura melhor orientar médicos e consumidores.

Para tanto a procura de um material de baixo custo e com biocompatibilidade tem sido uma constante na literatura. Portanto, esse trabalho teve como objetivo testar experimentalmente implante de polietileno granulado de ultra-alto peso molecular, material de baixo custo, em órbitas de coelhos submetidos à evisceração cirúrgica em vários tempos experimentais, onde foram avaliados aspectos macroscópicos e microscópicose de toxicidade sistêmica do material. MÉTODOS: Para esse estudo foram utilizados coelhos Oryctolaguscuniculus submetidos à evisceração do globo ocular direito e posteriormente implantados com esfera de polietileno granulado de ultra-alto peso molecular e analisados por 15, 30, 90 e 180 dias pós-implante, com parâmetros macro, microscópios e bioquímicos. Os animais controles foram submetidos ao mesmo procedimento sem, entretanto a colocação do implante. RESULTADOS: Os resultados desse trabalho mostram que o material utilizado no implante de cavidade não apresenta alteração significativa nos parâmetros de peso e bioquímicos quando comparados ao grupo controle. O material implantado apresentou uma grande interação com o tecido do hospedeiro. CONCLUSÃO: Os resultados indicam que implante de polietileno granulado de alto peso molecular desenvolvido por uma indústria nacional tem alto potencial para se realizar testes em humanos.

OBJETIVOS: Estudar os efeitos clínicos da secreção das glândulas salivares labiais na lubrificação das cavidades anoftálmicas secas, avaliar a durabilidade dos resultados e apresentar a técnica do transplante. A aplicação desse procedimento em cavidades anoftálmicas secas é inédita na literatura. MÉTODOS: Estudo prospectivo das cirurgias de enxertos glândulo-mucosos, compostos pela mucosa labial e glândulas salivares subjacentes, colocados no fórnice conjuntival de 5 pacientes com cavidades anoftálmicas que apresentavam grave xeroftalmia e retração dos fórnices conjuntivais. As cirurgias foram realizadas durante o período de julho/00 a janeiro/09. Dois pacientes já haviam sido tratados previamente com enxertos de mucosa ou de pele. A técnica do procedimento é descrita em detalhes. Os parâmetros que serviram para a análise comparativa dos resultados foram o quadro clínico, o aspecto do revestimento da cavidade, o ressecamento da superfície da prótese e a frequência do uso de colírios lubrificantes. RESULTADOS: Em todos os casos foi constatada a integração do enxerto e a melhora dos parâmetros avaliados. A evolução mostrou persistência e estabilidade dos resultados. CONCLUSÕES: A lubrificação da superfície da cavidade produzida pela secreção salivar mostrou ser eficiente, bem tolerada e constante, resultando maior conforto do uso da prótese. Infere-se que essa melhor lubrificação obtida ajuda a prevenir a evolução do processo de retração da cavidade. O transplante das glândulas salivares labiais para o fórnice conjuntival demonstrou ser um procedimento de fácil execução, acessível a qualquer cirurgião oftalmologista. PURPOSE: To study the clinical effects of labial salivary glands' secretion used as ocular lubricant in anophthalmic cavities with severe xerophthalmia; to evaluate the evolution of the results; and to present the surgical technique. This procedure application in dry anophthalmic cavities is new in the literature. METHODS: Prospective study of patients presenting anophthalmic cavities with severe xerophthalmia and conjunctival fornix retraction treated with labial salivary glands transplantation to the conjunctival fornices. The surgeries were performed in five patients during the period of July 2000 to January 2009. In two cases the fornix retraction was previously treated with mucosa or skin graft. The surgical procedure technique is described in details. The postoperative comparative analysis was based on the clinical picture, the cavity surface aspect, the dryness of the cavity and prosthesis and the frequency of lubricant eye drops use. RESULTS: In all cases both graft integration and improvement of the evaluated parameters were observed. The evolution proved the persistence and stability of the results. CONCLUSION: The salivary secretion produced by the transplanted labial glands proved to be efficient as conjunctival lubricant, well tolerated and permanent, making the use of the prosthesis more comfortable. This improvement helps to prevent the progression of the cavity retraction process. Labial salivary glands graft into the anophtalmic cavity is a simple procedure and accessible to any ophthalmic surgeon.

Apresentamos um novo modelo de implante orbital unindo o baixo custo da esfera de luxite (PMMA) com as vantagens da utilização do polietileno poroso (Porex®). O novo modelo consiste de uma esfera de luxite na qual em sua face anterior foi colocado um recorte de dura-máter do mesmo diâmetro da esfera, e na face posterior um recorte de polietileno poroso foi anexado à esfera de luxite por meio de cola (Cianoacrilato estéril). A dura-máter foi fixada ao polietileno poroso por meio de suturas com fio nylon monofilamentar 6.0. Foi realizada cirurgia em um paciente que já havia tido extrusão anterior do implante em um dos olhos, sendo este avaliado em seu pós-operatório imediato, 7º, 15º, 30º dia, além de 3 e 6 meses de pós-operatório quando foi avaliado por meio de tomografia computadorizada. Observou-se bom resultado cosmético, de mobilidade e de volume após adaptação da prótese escleral, não havendo nenhum sinal de infecção, migração ou extrusão do implante até o momento. O caso nos mostrou ser possível a utilização de um implante orbital mais acessível economicamente com resultados semelhantes aos dos implantes biointegráveis. A new model of orbital implant, matching the low cost of acrylic implants (PMMA) with the advantages of medpor (Porex®) is presented herein. The new implant model consists of a PMMA implant with a dura mater scrap adhered on its anterior face of the same diameter of the acrylic implant and a medpor snip adhered on its posterior face by sterile cyanoacrylate. Dura mater was fixed to medpor with 6.0 mononylon. One patient who presented previous extrusion of the implant was submited to surgery and was evaluated on the 1st, 7th, 15th, 30th postoperative days, and 3 and 6 months after surgery when a computed tomography was performed. A good cosmetic, mobility and volume result was noted after an escleral prosthesis was adapted, with no infection, migration or extrusion of the implant until this moment. This case showed us that it is possible to use a more economic implant model with the same results of medpor (Porex®).
