Normal Size Symmetrically Aligned Blind Eye
Whenever there is symmetrical alignment of the catoptric
image (light reflex) and the dysfunctional globe's cornea
and/or iris is the only disfigurement, there is no need to
duplicate any other portion of the eye (namely, the sclera
and conjunctival tissue with its vascular pattern).
This case presents a rare congenital (dermoid cornea) anomaly,
but it would be handled the same as an acquired condition
where the cornea was scarred or disfigured.
Figure 7A
The external appearance of the left eye was normal with exception
of the dermoid (insensitive) cornea. The sclera conjunctiva
was white and quiet and was the same as the fellow eye. It
is also noted that the catoptric image (light reflex) for
pupil center was also in alignment with the sighted eye.
Figure 7B
All that was required to restore semblance of facial symmetry
was to utilize the flush fitting Phase I trial shell with
an embedded hand painted brown iris of equal diameter.
Figure 7C
Since the cornea has no sensitivity this patient is able
to wear the cover shell at bedtime, but will remove it daily
for hygiene care, and will return to the ocularist on a periodic
basis to have it checked and reglazed.
