Persistent Monkeypox-Associated Keratouveitis in a Post-LASIK Cornea: A Case Report With Flap Removal.

Purpose: This study aimed to report a case of persistent keratouveitis associated with mpox virus infection in an immunocompetent patient with a history of laser-assisted in situ keratomileusis (LASIK), leading to the need for flap removal.

Methods: A comprehensive literature review was conducted, and a detailed case report was presented.

Results: A 44-year-old immunocompetent male patient with a history of LASIK and HIV infection presented with conjunctival and corneal lesions indicative of mpox infection.

Oxidative Stress Mediates Epigenetic Modifications and the Expression of miRNAs and Genes Related to Apoptosis in Diabetic Retinopathy Patients.

Knowledge on the underlying mechanisms and molecular targets for managing the ocular complications of type 2 diabetes mellitus (T2DM) remains incomplete. Diabetic retinopathy (DR) is a major cause of irreversible visual disability worldwide. By using ophthalmological and molecular-genetic approaches, we gathered specific information to build a data network for deciphering the crosslink of oxidative stress (OS) and apoptosis (AP) processes, as well as to identify potential epigenetic modifications related to noncoding RNAs in the eyes of patients with T2DM.

Oxidative Stress, Inflammatory, Angiogenic, and Apoptotic molecules in Proliferative Diabetic Retinopathy and Diabetic Macular Edema Patients.

The aim of this study is to evaluate molecules involved in oxidative stress (OS), inflammation, angiogenesis, and apoptosis, and discern which of these are more likely to be implicated in proliferative diabetic retinopathy (PDR) and diabetic macular edema (DME) by investigating the correlation between them in the plasma (PLS) and vitreous body (VIT), as well as examining data obtained from ophthalmological examinations. Type 2 diabetic (T2DM) patients with PDR/DME (PDRG/DMEG; n = 112) and non-DM subjects as the surrogate controls (SCG n = 48) were selected according to the inclusion/exclusion criteria and programming for vitrectomy, either due to having PDR/DME or macular hole (MH)/epiretinal membrane (ERM)/rhegmatogenous retinal detachment. Blood samples were collected and processed to determine the glycemic profile, total cholesterol, and C reactive protein, as well as the malondialdehyde (MDA), 4-hydroxynonenal (4HNE), superoxide dismutase (SOD), and catalase (CAT) levels and total antioxidant capacity (TAC).

Atypical herpes zoster ophthalmicus with madarosis of upper eyelid, recurrent iridocyclitis and atrophic multifocal chorioretinopathy.

Introduction: Ocular involvement due to varicella-zoster virus (VZV) infection includes conjunctivitis, scleritis, keratitis, uveitis, and necrotizing retinitis. Non-necrotizing chorioretinopathy as a late manifestation has been described.

Case Report: A 50-year-old immunocompetent man developed herpes zoster ophthalmicus (HZO) in the right V1 dermatome with acute anterior uveitis (AAU) treated with oral valaciclovir and topical steroid and a chalazion in the upper eyelid with associated madarosis.
