ABSTRACT

ABSTRACT Purpose: The purpose of this study was to determine the indications and frequency of evisceration after penetrating keratoplasty (PK). Methods: The medical records of all patients who underwent evisceration after PK between January 1, 1995 and December 31, 2015 at Ankara Training and Research Hospital were reviewed. Patient demographics and the surgical indications for PK, diagnosis for evisceration, frequency of evisceration, and the length of time between PK and evisceration were recorded. Results: The frequency of evisceration was 0.95% (16 of 1684), and the mean age of the patients who underwent evisceration was 56.31 ± 14.82 years. The most common indication for PK that resulted in evisceration was keratoconus (37.5%), and the most common underlying cause leading to evisceration was endophthalmitis (56.25%). The interval between PK and evisceration ranged from 9 to 78 months. Conclusions: Although keratoplasty is one of the most successful types of surgery among tissue transplantations, our findings show that it is associated with a possible risk of evisceration.


RESUMO Objetivo: O objetivo deste estudo foi determinar as indicações e a frequência de evisceração ocular após cirurgia de ceratoplastia penetrante ou transplante de córnea (PK). Métodos: Foram analisados os registros médicos de todos os pacientes submetidos à evisceração após PK entre 1º de janeiro de 1995 e 31 de dezembro de 2015 no Hospital de Treinamento e Pesquisa de Ankara. Foram registradas a demografia do paciente e as indicações cirúrgicas de PK, diagnóstico de evisceração, frequência de evisceração, tempo entre PK e evisceração. Resultados: A frequência de evisceração foi de 0,95% (16 de 1684) e a média de idade foi de 56,31 ± 14,82 anos. A indicação mais comum para PK que terminou na evis ceração foi o ceratocone (37,5%) e a causa subjacente à evisceração foi a endoftalmite (56,25%). O intervalo entre PK e evisceração variou de 9 a 78 meses. Conclusão: Embora a ceratoplastia seja uma das cirurgias mais bem sucedidas entre os transplantes de tecidos, pode-se deduzir do estudo que não é tão inócua, pois pode evoluir para a evisceração ocular.

ABSTRACT

ABSTRACT Purpose: To determine the outcomes of penetrating keratoplasty (PK) for treatment of corneal scarring caused by Herpes simplex virus (HSV) keratitis, and whether the corneal scar type affects treatment outcome. Methods: A retrospective analysis of patients who underwent PK for HSV-related corneal scarring between January 2008 and July 2011 was performed. The patients were categorized into two groups. Group 1 consisted of patients with a quiescent herpetic corneal scar and group 2 consisted of patients who developed a corneal descemetocele or perforation secondary to persistent epithelial defects with no active stromal inflammation. The mean follow-up was 21.30 ± 14.59 months. The main parameters evaluated were recurrence of herpetic keratitis, graft rejection, graft failure, visual acuity, and graft survival rate. Results: There were 42 patients in group 1 and 13 in group 2. Preoperative BCVA varied from hand movements to 0.7 logMAR. Postoperatively, 34 patients (61.8%) achieved visual acuity of 0.6 logMAR or more. Recurrence of HSV keratitis was noted in 12 (28.57%) eyes in group 1 and 4 (30.76%) eyes in group 2 (p=0.40). Graft rejection occurred in 4 eyes (9.52%) in group 1 and in 3 (23.07%) eyes in group 2 (p=0.58). The 1-, 2-, and 3-year graft survival rates were 91.9%, 76.0%, and 65.1% in group 1, and 89.5%, 76.0%, and 63.6% in group 2 (p=0.91), respectively. Conclusions: Although there were different recurrence and graft rejection rates for two groups, the graft survival rates at 3 years were similar. According to our results, without inflammation, corneal herpetic scarring with a descemetocele or perforation achieved similar graft survival rates with quiescent herpetic corneal scars.


RESUMO Objetivo: Determinar os resultados da ceratoplastia penetrante (PK) para o tratamento da cicatriz da córnea consequente à ceratite por Herpes simplex vírus (HSV), e se o tipo de cicatriz na córnea afeta o resultado cirúrgico. Métodos: Foi realizada análise retrospectiva dos pacientes, submetidos à PK para a cicatriz da córnea relacionados com o HSV entre janeiro de 2008 e julho de 2011. Os pacientes foram divididos em dois grupos. Grupo 1 consistiu de pacientes que tiveram cicatriz corneana herpética quiescente e grupo 2 consistiu de pacientes que desenvolveram descemetocele ou perfuração córnea secundária a defeitos epiteliais persistentes sem inflamação estromal ativa. O seguimento médio foi de 21,30 ± 14,59 meses. Os principais parâmetros avaliados foram recorrência de ceratite herpética, rejeição de enxerto, falência do enxerto, acuidade visual e taxa de sobrevida do enxerto. Resultados: Foram avaliados 42 pacientes do grupo 1 e 13 doentes do grupo 2. Acuidade visual pré-operatória variou de movimentos das mãos (HM) para 0,7 logMAR. No pós-operatório, 34 pacientes (61,8%) atingiram acuidade visual de 0,6 logMAR ou melhor. Doze olhos (28,57%) tiveram recorrência de HSV ceratite no grupo 1, e quatro olhos (30,76%) tiveram recorrência no grupo 2 (p=0,40). A rejeição do enxerto ocorreu em 4 olhos (9,52%) no grupo 1, e em 3 olhos do grupo 2 (23,07%; p=0,58), taxa de sobrevivência do enxerto foi de 91,9% a 1 ano, 76,0% aos 2 anos e 65,1% aos 3 anos no grupo 1, e 89,5% a 1 ano, 76,0% aos 2 anos e 63,6% aos 3 anos no grupo 2 (p=0,91). Conclusões: Embora diferentes taxas de recorrência e de rejeição do enxerto foram encontradas nos dois grupos, a taxa de sobrevida do enxerto em 3 anos foi semelhantes nos dois grupos. De acordo com nossos resultados, em casos sem inflamação, a cicatriz herpética da córnea com descemetocele ou perfuração demonstra as taxas de sobrevivência do enxerto semelhantes às da cicatriz corneana herpética quiescente.

ABSTRACT

Ligneous conjunctivitis (LC) is a rare form of bilateral chronic recurrent disease in which thick membranes form on the palpebral conjunctiva and other mucosal sites. We report the clinical features and describe the management of two cases. Case 1 was an 8-month-old patient with bilateral membranous conjunctivitis. Case 2 was a 5-year-old patient with unilateral membranous conjunctivitis, esotropia, mechanical ptosis and complicated cataract, and had been treated with a number of medications. Histological investigation of the membrane in both cases showed LC. Treatments with amniotic membrane transplantation and institution of topical cyclosporine have shown good response. There has been complete resolution of the membranes with no recurrence at the end of 40- and 28-month follow-ups, respectively. No treatment related side effects were seen. Thus, it appears that amniotic membrane transplantation and topical cyclosporine are effective alternatives for the treatment of LC.
