Tungiasis infestation of dermis fat graft in an anophthalmic socket.

A patient with an anophthalmic socket with a dermis-fat graft (DFG) developed inflammation and a foul odour in the right socket. The DFG was surgically removed and Tungiasis infestation was detected. This is the first case to report Tungiasis infestation in a DFG in an anophthalmic socket.

Chronic Orbital Inflammation Associated to Hydroxyapatite Implants in Anophthalmic Sockets.

PURPOSE: We report 6 patients who received a hydroxyapatite (HA) orbital implant in the socket and developed chronic orbital inflammation unresponsive to conventional medical therapy. CASE REPORTS: We assisted 6 cases (4 males, 2 females) who received an HA orbital implant in the socket between 2015 and 2016 at King Khaled Eye Specialist Hospital, Riyadh, Saudi Arabia, and developed chronic orbital inflammation with chronic discharge, redness, and pain (onset from weeks to over 2 decades after surgery). Computed tomography evaluation indicated inflammation in the orbital tissues, and histological examination showed a foreign body granulomatous reaction mainly localized around and blanching the HA implant. The condition was unresponsive to usual medical treatment and was resolved immediately after implant removal. CONCLUSIONS: Chronic inflammation can occur decades after placement of an HA implant in the orbit and can be successfully treated with implant removal.

Afecciones de la conjuntiva en pacientes con prótesis ocular / Conjunctival diseases of patients with ocular prothesis

OBJETIVOS: determinar las afecciones conjuntivales en pacientes con prótesis ocular. MÉTODOS: estudio observacional descriptivo longitudinal prospectivo, conformado por 62 pacientes (65 cavidades anoftálmicas) quienes acudieron al Servicio de Oculoplastia del Instituto Cubano de Oftalmología "Ramón Pando Ferrer" en el período de mayo a diciembre de 2010. Se analizaron la edad, el sexo, las causas de la pérdida ocular, el ojo afectado, la afección conjuntival, el tipo de cavidad, el tiempo de uso protésico, el resultado microbiológico, el manejo higiénico y la respuesta al tratamiento. RESULTADOS: se presentaron 23 pacientes de 40 a 59 años (37,1 %), de los cuales el sexo masculino mostró el 66,1 %. El traumatismo reveló el 40,3 % y el ojo derecho el 50 %. El 33,8 % presentó conjuntivitis alérgica; las retracciones de la conjuntiva reportaron el 18,5 %. El 67,5 % correspondió a cavidades atípicas con un tiempo de más de 366 días en el uso de la prótesis ocular. El resultado microbiológico positivo en 55 cavidades fue de 84,6 %. Se aisló el Staphylococcus aureus en el 70,9 % y de ellos el 41,5 % se efectuó con manejo diario de la prótesis. La respuesta al tratamiento fue buena en el 76,4 %. CONCLUSIONES: las afecciones conjuntivales de los pacientes con prótesis ocular constituyen un problema de salud. Asimismo, la mayoría de las cavidades anoftálmicas son atípicas en adultos, con pérdida del globo ocular por traumatismo. La conjuntivitis alérgica y la retracción conjuntival son las afecciones más frecuentes en los pacientes con prótesis ocular de más de un año de uso, por la presencia de Staphylococcus aureus a consecuencia de mayor manipulación higiénico protésica, aunque en la mayoría de los casos existe buena respuesta al tratamiento.

OBJECTIVES: to determine the conjunctival diseases of patients with ocular prosthesis. METHODS: prospective, longitudinal, descriptive and observational study of 62 patients (65 anophthalmic cavities) who went to the Oculoplasty service of "Ramon Pando Ferrer" Cuban Institute of Ophthalmology from May to December 2010. Age, sex, causes of eye loss, affected eye, conjunctival disease, type of cavity, length of time of prosthesis use, microbiological result, hygienic handling and response to treatment were the analyzed variables. RESULTS: in the studied group, the 40-59 y age group accounted for 37,1 % of patients; males were predominant with 66,1 %. Traumatism was observed in 40,3 %, being the right eye the most affected in 50 % of cases. Likewise, 33,8 % presented with allergic conjunctivitis and 18,5 % had conjunctival retractions. Atypical cavities represented 67,5 % with over 366 days of using the ocular prosthesis. The positive microbiological result was found in 55 cavities for 84,6 %. Staphylococcus aureus was isolated in 70,9 % of cavities and 41,5 % with daily handling of the ocular prosthesis. The response to treatment was good in 76,4 % of patients. CONCLUSIONS: conjunctival diseases in patients with ocular prosthesis are a health problem. Similarly, most of the anophthalmic cavities are atypical in adults with loss of eyeball from traumatism. Allergic conjunctivitis and conjunctival retraction are the most frequent illnesses in the patients wearing ocular prosthesis for more than one year, due to Staphylococcus aureus presence resulting from frequent hygienic handling of the prosthesis. The majority of patients positively responded to treatment.

Análise da biocompatibilidade de cones de biovidro e biovitrocerâmico (Biosilicato®) em cavidade eviscerada de coelho / Biocompatibility analisys of Bioglass® 45S5 and Biosilicate® cone in rabbit eviscerated cavity

OBJETIVO: Avaliar experimentalmente a biocompatibilidade de cones de biovidro e biovitrocerâmico em cavidades evisceradas de coelhos. MÉTODOS: Foram utilizados 45 coelhos albinos submetidos à cirurgia de evisceração do olho direito, seguida da inclusão de cones de biovidro e dois tipos de biovitrocerâmicos (chamados de FI e FII) na cavidade escleral. Os animais foram sacrificados em três momentos (7, 90 e 180 dias). Os parâmetros avaliados foram: peso, exame clínico diário, exames bioquímicos, avaliação histológica, exame morfométrico. RESULTADOS: Os animais mantiveram-se saudáveis durante o experimento, não tendo ocorrido extrusão do implante em nenhum animal. O exame morfológico mostrou que houve a formação de pseudocápsula ao redor dos cones, com superioridade dos cones de biovidro e biovitrocerâmico FI, os quais apresentaram menor reação inflamatória e menor formação da pseudocápsula ao redor dos cones que os demais. A reação inflamatória foi mais intensa após 7 dias da colocação dos cones, diminuindo em direção aos 180 dias, sendo menos intensa nos coelhos que receberam cones de biovidro. CONCLUSÃO: Os cones de biovidro e biovitrocerâmico FI e FII podem ser úteis para a reparação da cavidade anoftálmica, com melhor resposta quando se usa cones de biovidro e de biovitrocerâmico FI.

OBJECTIVE: To evaluate bioglass, bioglassceramic biocompatibility in rabbit's eviscerated cavities. METHODS: Forty- five rabbits were submitted to right eye evisceration, followed by the inclusion of bioglass and bioglassceramic I e II prosthesis in the escleral cavity. The animals were sacrificed at seven, 90 and 180 days after surgery. The animals had daily clinical exam; biochemical exam, histological analysis and morphometric evaluation. RESULTS: The animals stayed healthy during the expriment, with good cone integration to the host tissue. None cone extrusion were observed. Histologically, it was observed pseudocapsule formation around the cones and the inflammatory reaction was higher at M1, getting progressively lower while getting at M3, being the lowest in rabbits which received bioglass cones (GA) than at any other groups. CONCLUSION: Bioglass and bioglassceramic I e II cones can be useful to repair anophthalmic cavity.

Gel and porous polyethylene implants for anophthalmic cavity reconstruction-evaluation using the B scan ultrasound / 国际眼科杂志(Guoji Yanke Zazhi)

AIM: To evaluate the host response of the gel and porous polyethylene implants in anophthalmic cavities using the B scan ultrasound.placement of gel or porous polyethylene spheres implants. The animals were submitted to clinical examination weekly and to ultrasound evaluation on 30, 60 and 90 days after surgery. Implant extrusion probably because the gel spheres have hydrated and increased in volume. The B ultrasound of the gel polyethylene implant did not show vessels inside during the following period. Five animals (27.8%) with porous polyethylene spheres presented implant extrusion after 30 days of surgery. According to B ultrasound, the porous polyethylene implant showed irregular and heterogeneous architecture and reflective peaks similar to vascularized tissues. Gel polyethylene implant necessary to correct the diminished orbital content in the anophthalmic cavity. The B ultrasound effectiveness showed in this study for anophthalmic socket implants evaluation provided useful information for further in vivo studies and might substitute expensive methods of implants vascularization evaluation.
