Posttraumatic iris implantation cysts are rare ocular findings that are often associated with poor visual outcomes. Iris implantation cysts can present clinicians with diagnostic and therapeutic challenges given their variable presentations and frequently destructive nature. In this paper, we provide descriptions of two unusual cases of posttraumatic iris implantation cysts. The first case is o...

After lentectomy of the adult newt eye, non-dividing iris epithelial cells re-enter the cell cycle. Some of the iris epithelial cells become completely depigmented while they are in the cell cycle, and then differentiate into lens cells. The remaining iris epithelial cells become partially depigmented in the induced cell cycle, but resynthesize melanosomes and recover the normal state of iris e...

A 25 year old woman was found to have on routine microscopic examination of her right eye a deformation of the iris surface with bulging in the anterior chamber (Figure 1). No lesion was found after wide dilation of the pupil in primary gaze. By adjusting the slip lamp beam to the side and positioning the patient’s eye in far gaze, a smooth slightly pigmented cystic lesion was found (Figure 2)....

Immunohistochemical characterization of 14 cases of intracranial cysts was performed. Among these 14 cases, five different types of cysts were represented; Rathke's cleft cyst (4 cases), neurenteric cyst (2 cases), colloid cyst (1 case), choroidal epithelial cyst (2 cases) and arachnoid cyst (5 cases). Immunohistochemical evaluation utilized antibodies to glial fibrillary acidic protein (GFAP),...
