It has also been used to reinforce the zonule
in cases of zonular dehiscence or to facilitate the phacoemulsification in traumatic cataracts (MARQUES et al.
Gray's Anatomy of the Human Body online reproduces 1247 of Gray's original engravings and contains over 13,000 subject entries--as the website says, "from the Antrum of Highmore to the Zonule
The surgeon must be careful not to be aggressive during aspiration and irrigation of cortex, so as to avoid posterior capsule rupture or zonule
rupture during these manoeuvers.
b Pseudo-exfoliation syndrome reduces the risk of lens zonule
Also, if a large rhexis tears, the anterior zonule
insertions may be disrupted.
Rotary shadowing of elastic system microfibrils in the ocular zonule
, vitreous, and ligamentum nuchae.
PXF has also been known to cause a weakening of lens zonules
leading to lens drop and other complications during cataract surgery.
10 Also, it's common observation that cataract surgery in vitrectomized eye is more challenging than routine cases due to harder nucleus, variable and unstable AC dynamics, weak zonules
and possibility of posterior capsular damage during PPV.
The younger white population who are slightly myopic may present with lens zonules
rubbing on the back of the iris causing pigment dispersion syndrome (PDS); (15) this results in iris transillumination, in a ring in the middle of the iris.
In pseudoexfoliation syndrome, the lens zonules
are more fragile and have diminished elasticity, and spontaneous intraocular lens dislocation may occur due to capsular fibrosis.
This developmental anomaly is caused by the failure of closure of fetal fissure and is often associated with several other ocular anomalies, including iris coloboma, loss of inferior lens zonules
, cataract and optic disc abnormalities.
Pigment dispersion syndrome (PDS) results from posterior bowing of the iris and rubbing between the lens zonules
and epithelial layer of the iris, and usually affects myopic eyes in men during the third to fourth decade of life.
