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.

Purpose: The aim was to assess the visual impact of ocular wavefront aberrations, corneal thickness, and corneal light scatter prospectively after performing a Descemet stripping automated endothelial keratoplasty (DSAEK) in humans.

Methods: Data were obtained prospectively from 20 eyes preoperatively and at 1, 3, 6, and 12 months post-DSAEK. At each visit, the best spectacle-corrected visual acuity and visual acuity with glare (brightness acuity testing) were recorded, and ocular wavefront measurements and corneal optical coherence tomography (OCT) were performed.

Purpose: To investigate the contribution ocular aberrations have on visual performance by quantifying improvements in best-corrected visual acuity (VA) and contrast sensitivity (CS) obtained with higher-order aberration (HOA) correction after penetrating (PK), deep anterior lamellar (DALK), or Descemet's stripping automated endothelial keratoplasty (DSAEK).

Methods: Sixteen eyes were evaluated from 14 subjects who underwent PK (n = 5), DALK (n = 6), or DSAEK (n = 5) greater than 1 year prior to study enrollment. Ocular aberrations were measured and an adaptive optics system was used to correct ocular lower-order aberration (LOA) and HOA.

Purpose: To describe a case of Langerhans cell histiocytosis (LCH) that involved the anterior uveal tract.

Design: Interventional case report.

Methods: A retrospective review was conducted on a patient with iris nodules and anterior uveitis in the setting of LCH.

Background: Therapeutic use of adrenal corticosteroids is a risk factor for the development of posterior subcapsular cataract (PSC). Because corticosteroids are given to donors of apheresis granulocytes (PMNs) to improve yield, this study was performed to determine the prevalence of PSCs in PMN donors relative to a matched control group of apheresis platelet (PLT) donors.

Study Design And Methods: This study was a cross-sectional study stratified by age, sex, and lifetime apheresis experience at three sites.

Purpose: To report the case of a patient with upper eyelid chronic cicatrizing conjunctivitis and entropion, presumably secondary to ocular rosacea.

Methods: Case report and review of medical literature.

Results: The patient has a history of chronic cicatrizing conjunctivitis since 1999.
