Clinical picture of epidemic keratoconjunctivitis was studied in 232 patients. The patients were divided into 3 groups. Group I included 147 patients with a monoinfection: Group 2 consisted of 70 epidemic keratoconjunctivitis patients after surgery for cataracts and glaucoma; Group 3 included 15 patients with epidemic keratoconjunctivitis and ophthalmic herpes. Some differences in the relative incidence of clinical signs and in the course of the condition were detected in the patients after surgery. Clinical course of epidemic keratoconjunctivitis paralleled by ophthalmic herpes was not characterized by a clear-cut staged pattern. Adenoviral ophthalmic infection coursed less severely than usual.

Epidemic keratoconjunctivitis (EKC) is one of the most severe clinical manifestations of human adenovirus ocular surface infection, which may lead to the formation of subepithelial infiltrates (SEIs) in the anterior corneal stroma in 20-50 % of cases. SEIs may be asymptomatic or give rise to corneal aberrations and visual impairment for months or years after acute infection, despite treatments. Here, we describe the ultrastructural and immunophenotypic features of the anterior corneal stroma of a patient who underwent superficial anterior lamellar keratoplasty (SALK) surgery to remove corneal opacities related to clinically significant and steroid-unresponsive, long-lasting SEIs after adenoviral EKC.

To date, the pathogenesis of corneal SEI formation in EKC is unresolved. HMGB1 (high-mobility group box 1 protein) is an alarmin expressed in response to infection and a marker of sepsis.

Pediatric blepharokeratoconjunctivitis (PBKC) is a chronic and recurrent ocular surface inflammatory disorder affecting children in early life. It is frequently under- or late- diagnosed, representing a potential cause of severe visual morbidity worldwide. An expert panel consensus recently agreed on its definition and proposed diagnostic criteria for suspected and definitive PBKC to reduce confusion and avoid varied terminology previously used in the literature, improving early and precise diagnosis.

Certain species D human adenoviruses (HAdV-D19, -D37, and -D64) are causative agents of epidemic keratoconjunctivitis. HAdV-D37 has previously been shown to bind CD46 (membrane cofactor protein) and sialic acid as adhesion receptors. HAdV-D64 is genetically highly similar to HAdV-D37, with an identical fiber protein sequence, but differs substantially in its penton base and hexon proteins, two other major capsid components, due to genetic recombination.

Inflammatory bowel disease (IBD) is a complex, multisystemic disease and is associated with ocular pathology in 4-12% of patients. In general, ocular disease affects Crohn's patients more frequently than those with ulcerative colitis. Episcleritis and uveitis are the most common presentations, with episcleritis often correlating with IBD flares, whereas uveitis presents independently of IBD activity and, in some cases, may even alert clinicians to a new diagnosis of IBD.
