Constructing a Computer Model of the Human Eye Based on Tissue Slice Images

Abstract: Computer simulation of the biomechanical and biological heat transfer in ophthalmology greatly relies on having a reliable computer model of the human eye. This paper proposes a novel method on the construction of a geometric model of the human eye based on tissue slice images. Slice images were obtained from an in vitro Chinese human eye through an embryo specimen processing methods. A level set algorithm was used to extract contour points of eye tissues while a principle component analysis was used to detect… Show more

“…In the clinical practice of ophthalmology, the geometric characterizations of the anterior segment have become a crucial analysis due to the multiple applications of the analysis on the anterior segment structures for optimizing corneal and intraocular refractive surgery procedures [ 10 , 11 , 12 ]. The shapes of the anterior segment are essential to the three-dimensional computer modeling of the human eye, especially to the personal eye modeling [ 13 , 14 ], the binocular eye modeling [ 15 ], and eye modeling under accommodation [ 16 , 17 ]. For optimum performance and ocular health, the contact lens and intraocular lens design require specific fitting principles to be adhered to.…”

“…Dentro del campo de la anatomía fisiológica del cuerpo humano, algunos autores proponen la caracterización morfológica simplemente para conocer su morfología real, como es el caso de la caracterización del ojo humano llevada a cabo por Wang et al (2010) y generada a partir de la definición del contorno de las imágenes realizadas sobre las secciones de corte al ojo en un escenario in vitro, es decir, fuera de un ambiente natural, utilizando para ello un equipo fotográfico. Sin embargo los autores manifiestan la dificultad de localización y adquisición de los datos de contorno de las imágenes generadas.…”

“…Algunos autores han realizado trabajos a partir de estos datos en bruto, como la caracterización geométrica de la córnea a partir de la evaluación de la simetría corneal utilizando parámetros de forma y posición (Bao et al, 2010), o el desarrollo de un modelo biomecánico personalizado basado en la obtención de la geometría del paciente (Roy y Dupss, 2011;Ariza-Gracia et al, 2015), ambos realizados a partir de las coordenadas cartesianas (x, y, z) aportadas por el topógrafo Pentacam.…”
