TECHNIQUE: LASER COSMETIC IRIDOPLASTY

After a few years of basic research and evaluation of possible alternatives, in 2012 we began the technological development and the clinical studies of the solution with laser application [14]. A priori offered two clear advantages over the previous possibilities, greater security because it is...

EYCL1 Gene

EYCL1 gene is responsible for the green and blue color of the eyes on chromosome 19. On chromosome 15 the responsible for the brown color is EYCL2 gene. Also in chromosome 15 it is EYCL3 gene that causes pigmentation of skin and hair, and whose...

Phenotype and genotype studies

To address the challenge of achieving good predictability of laser iridoplasty, we first had to clarify the scientific bases that determine the color of the eyes. The fundamental law is genetic and it is the Theory of the two genes, green and blue (Figure 6)....

HISTOLOGICAL AND ANATOMOPATHOLOGICAL STUDIES

We performed a series of studies with specialized anatomopathologists of corpse eyes with different degrees of pigmentation. The main conclusions we reached were the following (Figures 1, 2 & 3): Figure 1: Histological simple of a low pigmented iris. Eumelanin (dark pigment) is highly concentrated and...

HISTORY Of TREATMENT OF IRIS HETEROCHROMIA

Ocular cosmetic alterations have been treated conservatively so far with contact lenses and aesthetic prostheses, and through different types of surgical interventions. Deformities, irregularities, defects (colobomas) or total absences of the iris (anhiridia) have been treated with intraocular implants (Ophtec, Morcher or Dr Schmidt). In...

Acquired factors that can cause heterochromia

Siderosis or Hemosiderosis. These are deposits of iron on the iris that alter their normal color. It usually occurs as a result of trauma or eye surgery. • Fuch heterochromatic cyclitis. It is an infl ammation of the anterior chamber of the eye and is one of...

Appearance of heterochromia

If it appears from the moment the eye acquires its final coloration we are talking about congenital heterochromia and may be of genetic origin or be associated with other diseases such as neurofibromatosis. It can also appear throughout life as a result of injuries or other...

Types of iris heterochromia

Specifically, different types of heterochromia are established in the iris, since it can be both total and partial. Iridium or complete heterochromia. So it is called when the iris of the eyes differ from each other. Iridis or partial heterochromia. The person has two different...

What defines the color of the iris?

In a normal healthy eye, the color of the iris is defined by genetic inheritance. In children, initially the color is gray or light blue and it is between 6 and 10 months of age when the final color is fixed. This will depend on...
