Background: Atopic dermatitis (AD) is a common skin disorder of increasing prevalence. Many ophthalmologic conditions are associated with AD, including cataract formation. Posterior and anterior subcapsular cataracts have been described in AD. Topical and systemic corticosteroids have been implicated in the development of cataracts. The precise pathogenic mechanisms and risk factors for development of atopic cataract are not clear.
Observation: We report a case of cataract development in a child with severe AD and performed an extensive review of the dermatologic and ophthalmologic literature pertaining to AD and cataract formation. The incidence, demographics, pathogenesis, and characteristics of atopic cataracts are evaluated.
Conclusions: Atopic dermatitis alone is a risk factor to develop both posterior and anterior subcapsular cataracts. There is a slightly increased probability of posterior subcapsular cataracts. However, anterior subcapsular cataracts are more specific to AD. A positive correlation was found between atopic cataract development and a decreased inducibility of superoxide dismutase. This suggests that atopic cataract development is correlated with oxidative damage of the lens and related to chronic inflammation.

Chemoimmunotherapy-Resistant Ocular Surface Squamous Neoplasia Managed With I-125 Brachytherapy.

Department of Ophthalmology, Bascom Palmer Eye Institute, University of Miami Miller School of Medicine, Miami, FL.
Purpose: The purpose of this study was to report the management of chemoimmunotherapy-resistant ocular surface squamous neoplasia (OSSN) with iodine-125 (I-125) brachytherapy.
Methods: A 36-year-old man presented to the clinic with biopsy-proven OSSN that covered ∼70% of the corneal surface and extended to the 6 o'clock position of the inferior limbus of the OS. The visual acuity was 20/20 in the OD and 20/40 in the affected OS.
Introduction: This study evaluated the clinical outcomes of simultaneous implantable collamer lens (ICL) removal and phacoemulsification with intraocular lens (IOL) implantation in a multicenter study.
Methods: We retrospectively investigated 83 eyes of 72 patients requiring ICL extraction and cataract surgery at five institutions. Preoperatively and 3 months postoperatively, we determined visual acuity (logMAR), spherical equivalent refraction, and endothelial cell density (ECD), in addition to the preoperative backgrounds and the postoperative complications.

Epithelial mesenchymal transition (EMT) of lens epithelial cells (LECs) is one of the most important pathogenic mechanisms in lens fibrotic disorders, and the regulatory mechanisms of EMT have not been fully understood. Here, we demonstrate that the cAMP-response element binding protein (CREB) can regulate lens EMT in a phosphorylation-dependent and -independent manners with dual mechanisms. First, CREB-S133 phosphorylation is implicated in TGFβ-induced EMT of mouse LECs and also in injury-induced mouse anterior subcapsular cataract (ASC) model.

Extreme myopic laser-assisted in situ keratomileusis (LASIK) poses challenges regarding future intraocular lens (IOL) power selection. A male patient in his 40s complained of progressive right eye (OD) diminished visual acuity. He had a history of myopic LASIK in both eyes (OU) 20 years before, and implantable collamer lens (ICL) implant in OU 8 years before.
