In these unilateral cases, eye glasses may be worn to offer a measure of physical protection.A key aspect of managing this condition is accounting for the small volume of the eye. The small orbit size characteristic of microphthalmia can impact the growth and structural development of the face after birth. As a result, microphthalmia can cause hemifacial asymmetry. This possibility is a particular concern for individuals with unilateral cases of microphthalmia. With one eye of average size, the asymmetry often becomes much more severe as the child ages. An axial length of less than 16 mm (0.63 in) indicates that a microphthalmic eyes growth will not be sufficient, and intervention will be necessary to reduce the degree of facial asymmetry.Minimizing facial asymmetry is important for cosmetic and structural reasons. In order to address the size discrepancy of the affected eye(s), it is important to begin eye socket expansion early in life. The face reaches 70% of its adult size by roughly 2 years of age, and 90% of its adult size by about 5.5 years of age. Additionally, the symmetry fostered by early socket expansion allows for a better prosthetic fit later in life. Typically, an infant begins wearing a conformer, or an unpainted ocular prosthesis, in the first weeks of life. The conformer is repeatedly replaced with a prothesis of a slightly larger size. This process, which takes place during the first 5 years of life, gradually enlarges the eye socket.
