Neuroectoderm-derived iris muscle characterization at the single-cell resolution in native human iris and a pluripotent stem cell eye model [PDF]

open access: yesNature Communications
How the neuroectoderm-derived eye field breaks symmetry to specify iris muscle is not well understood. Recent studies have begun to transcriptionally characterize mouse iris muscle; however, little is known about the transcriptional foundation of human ...

A case of primary peripheral T-cell type non-Hodgkin lymphoma originating in the iris: Clinico-pathological findings [PDF]

open access: yesVojnosanitetski Pregled, 2010
Background. The ocular adnexal region is the primary localization of extranodal lymphoma in 5% to 15% of all Non-Hodgkin lymphoma. Intraocular lymphoma of T-cell origin is extremely rare and such sites of infiltration have been rarely observed in ...

Iris atrophy in sickle cell disease. [PDF]

open access: yesBritish Journal of Ophthalmology, 1986
Iris atrophy, of unknown origin and believed to be secondary to the vaso-occlusive process of sickle cell disease, has been observed in 25 eyes of 22 patients (two SS disease, 20 SC disease). The crude prevalence was highest in males with SC disease, in whom 14.7% of patients were affected.

Rare diseases leading to childhood Glaucoma. epidemiology, pathophysiogenesis, and management [PDF]

open access: yes, 2015
Noteworthy heterogeneity exists in the rare diseases associated with childhood glaucoma. Primary congenital glaucoma is mostly sporadic; however, 10% to 40% of cases are familial. CYP1B1 gene mutations seem to account for 87% of familial cases and 27% of

Detection of Iris Presentation Attacks Using Hybridization of Discrete Cosine Transform and Haar Transform With Machine Learning Classifiers and Ensembles

open access: yesIEEE Access, 2021
Iris biometric identification allows for contactless authentication, which helps to avoid the transmission of diseases like COVID-19. Biometric systems become unstable and hazardous due to spoofing attacks involving contact lenses, replayed video ...
