BackgroundOf the 10 patients with adenoviral type 54 keratoconjunctivitis examined at Nojima Hospital, 2 developed stellate keratitis and mutton-fat keratic precipitates (KPs) following acute symptoms.Case presentationWe encountered 10 cases of epidemic keratoconjunctivitis from August to October 2017. All patients were adults with a mean age of 60.910.0years. The species D human adenovirus (HAdV)-54 was detected in the conjunctival scrapings of these patients. Fluorometholone instillation was administered during the first week for acute symptomatic relief.Case 1: A 64-year-old female was prescribed with fluorometholone instillation, which was discontinued after 1week when her symptoms alleviated. One week after discontinuation of the instillation, she presented with blurred vision in her left eye with KPs and multiple stellate keratitis. The anterior chamber had no apparent cells. Her symptoms disappeared after 1week of betamethasone instillation.Case 2: A 66-year-old female was prescribed with 0.1% fluorometholone instillation, which was discontinued within10 days. Three months after the appearance of initial symptoms, multiple subepithelial corneal infiltrates (MSI) appeared in her eyes. Stellate keratitis and dark-brown pigmentation were observed in the centres of MSI, with several cells in the anterior chamber. Betamethasone was prescribed, and MSI and stellate keratitis improved within 1week. However, KPs were observed in the left eye. The instillation was continued for 3 more weeks until symptoms improved.ConclusionsMSI is an immune reaction that occurs after the disappearance of acute symptoms. Here, corneal findings and KPs were observed after improvement in eye redness and discontinuation of steroids. These symptoms were presumed to be secondary inflammation due to immune response to the adenoviral antigen.The clinical features of HAdV-54 keratoconjunctivitis on the ocular surface are initially moderate, but become active in the subacute to chronic phases. This may develop atypical findings, including stellate keratitis with KPs. Although early steroid administration can relieve acute symptoms, it may facilitate chronic corneal immunological reaction.
