Abstract:
A 15-year-old male patient presented with vision loss after blunt trauma to the right eye and with clinical evidence of posterior lenticonus. The posttraumatic lenticonus was eccentric (superotemporal). Irregular astigmatism with high myopia on dilated retinoscopy within the lenticonus, localized posterior convexity of peripheral capsule on ultrasound biomicroscopy, and increased higher-order aberrations (HOAs) on wavefront aberrometry compared with fellow-eye findings confirmed the diagnosis. To our knowledge, acquired peripheral posterior lenticonus representing dialysis of Weigert ligament after acute blunt trauma is a new finding. This case provides an insight into the pattern of higher HOAs associated with any type of lenticonus.

Dialysis
Acute kidney injury develops suddenly and can be caused by pre-renal causes (e.g., hypovolemia, shock), intrinsic renal causes (e.g., acute tubular necrosis), or post-renal causes (e.g., urinary obstruction). In contrast, chronic renal failure progresses gradually over time and is often...
