Anophthalmia: Complete absence of globe in presence of ocular adnexa
Microphthalmia: Globe with total axial length (TAL) < 2 standard deviations below mean for age
< 19 mm in 1 year old or < 21 mm in adult
Normal neonatal eye is 17 mm, achieves adult-sized globe by 3 years of age
Nanophthalmos: Type of simple microphthalmia + microcornea, bilateral TAL < 18 mm and hyperopia
