“…Endothelial keratoplasty first reported in 2008 in children is involves replacement of host Descemet's membrane with the donor membrane and its healthy endothelium. Descemet's stripping endothelial keratoplasty (DSAEK) has been reported successful in children suffering from pseudophakic corneal edema, congenital hereditary endothelial dystrophy, posterior polymorphous dystrophy, buphthalmos due to congenital glaucoma and failed grafts (Kymionis et al, 2012;Hashemi et al, 2012). DSAEK is more often considered and preferred as it avoids most problems faced following PKP.…”

Visual rehabilitation of pediatric corneal blinds is a major challenge to corneal transplant surgeons. Penetrating keratoplasty (PKP) is the only way to restore vision and prevent irreversible blindness due to amblyopia in children. Performing penetrating corneal grafts in children poses difficulty in evaluation, technical difficulties during surgery and problems during follow-up. Younger children do not cooperate for proper slit-lamp examination and need to be examined under general anaesthesia. In addition, the complications encountered post PKP, including allograft rejection, post PKP astigmatism and post PKP glaucoma are more frequent in pediatric group as compared to adult recipients. Even after a successful graft, the child requires rigorous treatment for amblyopia. Parents need to be counselled before surgery and possible visual outcome and chances of obtaining clear graft should be discussed.

“…Where OCT was available, one report (two cases of Peters anomaly)14 showed an irregular posterior optical zone, which explains the unusual retinoscopy reflex reported. The other four reports (10 failed graft, 8 CHEDs, 4 pseudophakic corneal oedema and 1 bee sting injury) showed OCTs with no such irregularity in the optical zone 1 4 6 10…”

RESUMOObjetivo: O objetivo deste estudo foi apresentar uma visão abrangente dos transplantes endoteliais, explicando as técnicas realizadas atualmente, vantagens, desvantagens e os principais desafios de sua evolução. Métodos: Estudo descritivo das principais técnicas de transplante endotelial realizadas, com base nos principais artigos publicados sobre o tema. Resultados: Existe uma considerável evolução dos transplantes endoteliais nas últimas décadas. Dessa forma, o número de transplantes realizados apresenta um crescente. Apesar dos avanços e vantagens dos endoteliais, a avaliação da qualidade visual dos enxertos preparados ainda é um desafio. Conclusão: A análise da interface óptica dos transplantes endoteliais é um dos caminhos para o entendimento da variação da qualidade visual de pacientes submetidos a diferentes técnicas de preparo dos enxertos corneanos. Esta análise poderá ajudar a compreender resultados visuais insatisfatórios com os transplantes endoteliais, apesar do excelente resultado anatômico. ABSTRACTObjective: This study aimed to present a broad overview of endothelial transplants and outline the techniques currently used and the advantages, disadvantages, and main challenges of advancements in the procedure. Methods: A descriptive study on the most frequently used techniques for endothelial transplantation based on the main articles published on the topic. Results: There have been considerable advancements in endothelial transplants in recent decades. Thus, the number of transplants performed has increased. Despite these advances and the advantages of endothelial transplantation, the assessment of the visual quality of the grafts is yet a challenge. Conclusion: Analysis of the optical interface of endothelial transplants can be used to understand variations in visual quality experienced by patients who underwent different corneal graft preparation techniques. This analysis may aid in the understanding of unsatisfactory visual results after endothelial transplants, which may occur despite excellent anatomical results.

Posterior Lamellar Keratoplasty (DSAEK) in Peters Anomaly

Abstract: Posterior lamellar keratoplasty (DSAEK) may be a promising option in properly selected cases of Peters anomaly. Further studies are needed to define the role of DSAEK or other types of posterior lamellar keratoplasty in this condition.
