This document provides a summary of various eye conditions visualized on b-scan ultrasound images by Dr. Alshymaa Moustafa. It begins with a description of a normal b-scan showing optic nerve shadow, retina, choroid, and sclera. Various pathological cases are then summarized, including cryptophthalmus showing a cyst with absent lens and iris, bilateral agenesis of the eyeballs, congenital cystic eye replacing the orbit, persistent hyperplasia of the primary vitreous, retrolental fibroplasia, bilateral congenital cataract, bilateral drusen, traumatic posterior lens dislocation, hypermature cataract, long standing traumatic cataract, giant retinal tear with
8. HRSG reveals a small cystic mass with absent lens
and iris in Rt orbit.
Normal Lt eye of the same patient.
9. Bilateral agenesis of eye
• A young child was born with small
orbital sockets and thin palpebral
fissure.
10. • HRSG shows bilateral agenesis of eyeballs with small palpebral fissure in the orbital socket.
Irregular cystic spaces are seen in both the orbits with small echogenic retrobulbar fat.
11. Congenital cystic eye
• Cystic mass is seen over the Lt orbit.
• Lt orbit shows two big cysts one in anterior part another in retrobulbar part communicating with
each other.
• Normal eye is absent.
12. • HRSG shows a small rudimentary cystic eye which is
engulfed by a big orbital cyst.
• Small amount of retrobulbar fat is seen posterior to the
rudimentary eye.
13. Persistent hyperplasia primary vitreous (PHPV)
• A young child was born with white eye reflex on ophthalmic examination in Lt eye.
• HRSG shows echogenic membranous vitreous with small Lt eye.
• The embryonic vitreous did not develop into normal transparent vitreous.
14. HRSG shows small Lt eye with thick lens and an echogenic band going from the lens to the posterior pole.
15. PHPV. Small Lt eye is seen with calcification of hyaloid artery and echogenic membranous vitreous.
16. Retrolental fibroplasia
HRSG shows a thick opaque lens with a posterior membrane and an echogenic band
going from the membrane to the posterior pole in a newborn child.
17. Bilateral congenital cataract
• An infant was born with white eye reflex in both eyes.
• HRSG shows echogenic thickened opaque lens in both eyes.
• Posterior segment of the eye is free.
18. Bilateral drusens
Echogenic calcification is seen at the
optic disc in both eyes.
It is accompanied with acoustic
shadowing.
Drusens is a calcification of optic disc
due to deposition of calcium specks over
optic disc.
