The reasons for these disorders developing could comprise of heritable mutations (alterations) and anomalous chromosomes. Investigators additionally consider that environmental aspects like being exposed to X-rays, chemical, toxic substances, drug forms, insect repellents, radiation or viral forms, raise the chances of developing microphthalmia and anophthalmia, however studies are inconclusive. At times, the cause for the condition developing in an individual cannot be ascertained.
Treatment
There is no cure for acute anophthalmia or microphthalmia which would help in creating new eyesight or in restoring vision. But, a number of less acute types of microphthalmia could show improvement following medical or operative treatments.
In majority of the scenarios, a child’s appearance could be improved. Prosthetic or artificial eye for aesthetic reasons could be affixed in such children for promoting socket development. A newly born baby having anophthalmia or microphthalmia would require visiting numerous eye care experts, inclusive of specialists in child care, vitreoretinal ailment, orbital-oculoplastic operations, ocular genetics and prosthetic tools.
Every expert could offer data and likely treatment providing guidance to the best possible eye care to the infant and kin. A prosthetic disease specialist for ocular problems would create conformers – plastic structure to assist in supporting the face and promoting eye socket growth. With facial development ensuing, novel conformers would become necessary to make. An infant having anophthalmia could additionally require expanders along with conformers for additional eye socket enlargement. When complete facial development has occurred, making and placing prosthetic eyes could be done though they would not be able to reinstate vision.
Appearance of Conformers and Prosthetic Eyes
A coloured prosthesis would appear quite similar to a normal eye and is generally affixed when the child is 1-2 years old. Till that time, clear conformers are deployed. After conformers have been placed in the eye socket they would appear black. Conformers are unpainted for making their appearance resemble normal eye as they often require change in time intervals of some weeks. The child would keep progressing to bigger-sized conformers till he/she is two years old.
In case a child would require wearing conformers after two years of age then conformers would be coloured alike usual prosthesis, offering the look of a normal however smaller-sized eye. By and large, a child would require 3-4 newly coloured prosthesis prior to reaching ten years of age.

Children having microphthalmia could have lingering or limited vision. In such scenarios patching the good-functioning eye would be done for strengthening eyesight in the microphthalmia-affected eye. Prosthesis could be used for capping to the microphthalmia-affected eye for assisting in gaining aesthetic look while residual vision preservation is attained.
