In certain rarer cases, various anomalies of the central nervous system, including hydrocephaly, lissencephaly, and agenesis of the corpus callosum as well as microcephaly,
microphthalmia, cleft lip and palate, diaphragmatic hernia, simian crease, and genitourinary anomalies, can also be seen (6).
Posterior microphthalmos is described as a subtype of
microphthalmia, in which the axial length is shortened in the posterior segment only.
Early orbita expansion is important to minimize facial deformity in cases of anophthalmia or severe
microphthalmia [7].
It seems unlikely that the crystallines were developed in this case of severe
microphthalmia. It is also unclear if false imaging of orbital cavities could be seen by gynecologists in such a rare condition, leading them to believe that crystallines developed.
Several congenital ocular defects in pigs, such as anophthalmia, macro- and
microphthalmia, and cyclopia, have been documented in the veterinary literature [1].
The parents elected to terminate the pregnancy at 26 weeks' gestation, and a 707 g male fetus was delivered with facial dysmorphisms including small mandible, thin lips, and right
microphthalmia. Bilateral absent thumb and polydactylism ( first finger at right hand) were also noted.
The eye exam should pick up any anomalies of the anterior and posterior eye, including
microphthalmia, coloboma, intraocular calcifications, optic nerve hypoplasia and atrophy, and macular scarring with focal pigmentary retinal mottling.
A modified International FA Registry (IFAR) score (using growth retardation, renal anomalies, thumb and/or radius anomalies,
microphthalmia and birthmarks (each scoring positive 1 if present) and other skeletal anomalies (scoring negative 1 if present, for a maximum score of 5)) was calculated for each patient.
Another important feature is that the tumor presents a melan-A expression that triggers HMB-45,
microphthalmia transcription factor and melanocytic differentiation of the tumor (2,17).
Little Stevie - named after singer Stevie Wonder - is guided by fellow shihtzu Max after being born with the eye condition
microphthalmia.
Stevie, a one-year-old shih tzu cross bichon, has a condition called
microphthalmia, which means he was born without eyesight.
The morphological observations of fetuses showed anomalies like open eye lid, distorted body axis, kyphosis, skin hemorrhage, drooping wrist,
microphthalmia, low set arm, kinky tail, exencephaly anophthalmia, maxillary macrognathia, microcephaly, clubbed foot and microtia.
