Abstract
Introduction:
Primary congenital glaucoma(PCG) is a rare genetically determined disease of the anterior chamber angle that results in elevated intra ocular pressure (IOP) with no ocular or systemic association. It has three variants according to the age of onset (newborn, infantile and late onset). There is also another variant which is the spontaneously arrested type. The "clinical triad" of symptoms including epiphora, photophobia and blepharospasm. The main clinical signs of PCG include elevated IOP >21 mmHg, corneal edema and/or enlargement of the eye with buphthalmos, and Haab striae. Medical treatment has a limited role in controlling the IOP in PCG, reducing IOP effectively in less than 10% of PCG patients, making surgery the mainstay of treatment of PCG. Visual prognosis depends on the degree of corneal scarring, anisometropia, refractive or deprivation amblyopia, and optic nerve damage. Wavefront mapping is a technology that makes custom laser eye surgery possible by precisely measuring and diagramming the aberrations of an optical system (e.g. the human eye). These aberrations are divided into lower-order aberrations (such as myopia, hyperopia, and astigmatism) and higher-order aberrations (such as trefoil, coma, and spherical aberration) that affect contrast sensitivity and night vision. The iTrace Device is an analyzer of visual functions and the optical system of the eye. This class 1 laser instrument is used to determine refractive errors, wavefront and corneal topography data of the optical system of the eye.
