Purpose: The aim of this study is to measure retinal vessel density and flow rate area by optical coherence tomography angiography (OCTA) in patients with autoimmune diseases taking hydroxychloroquine (HCQ).
Methods: The cross-sectional study included 98 patients divided into three groups. Group I included patients with the diagnosis of an autoimmune disease, for whom the introduction of HCQ was planned.
Background: Dry eye is a multifactorial disease defined less than 30 years ago. It is a relatively common disorder, affected by a number of well-known risk factors. Dry eye can be challenging to diagnose because of the possible discrepancy between patients' symptoms and clinical signs, and its overlap with other ocular surface diseases.

Apart from allergy, ER is a repetitive motor stereotypy. Eye rubbing is frequently observed in children with autism spectrum disorders (ASDs) and in individuals who may be at risk for developing KC.

A relationship between host gene polymorphisms and the recurrence of herpes simplex virus (HSV) infection has previously been proposed. Thus, the aim of this study was to investigate a potential association between the host genotype and recurrent HSK.

If not recognized and managed appropriately, it can be complicated by the potentially fatal condition ophthalmomyiasis interna. Ophthalmomyiasis externa is mainly caused by the sheep bot fly (Oestrus ovis).

We recently demonstrated that α-1,2-mannosidase I mRNA decreases in graft-infiltrating CD11c(+) dendritic cells (DCs) prior to allograft rejection. Although highly expressed in immature DCs, little is known about its role in DC functions.

Purpose: To analyze the immune modulatory effect of low-dose systemic treatment with rapamycin (Rapa) alone or in combination with cyclosporin A (CsA) in a high-responder corneal allograft model.
Methods: A total of 80 C57BL/6 mice received corneal grafts from BALB/c donors. Recipients were treated with either CsA 3 mg/kg/day or Rapa 0.
