Five weeks after fertilization, the mesoderm that surrounds the eye will give rise to the structures of the iris and related muscles, also including the sclera and eyelids. Birth defects such as optic nerve hypoplasia and microphthalmia may occur when alcohol is introduced into the developmental cycle.
After the sixth and seventh week of development, brain damage can occur to the developing fetus. The corpus callosum can become vulnerable to alcohol and as result can lead to the underdevelopment of that structure. In the eight week after fertilization, the exposure of the alcohol may not be enough to damage organ systems, but the central nervous system has the best chance of being affected at this point. The alcohol can affect the formation
