One-time low concentration betadine eye wash: A novel treatment for epidemic viral conjunctivitis for accelerated recovery
Abstract
PURPOSE: This study aims to renew the management of viral epidemic conjunctivitis by introducing a one-time, low-concentration ocular surface povidone-iodine (LOS-pI) wash.
METHODS: Among the 3,002 patients screened, 1,328 with acute conjunctivitis were categorized into two groups. Group A (664 patients) underwent a 1% betadine wash in addition to the standard treatment protocol (Eye Lubricant + Moxifloxacin 0.5% eyedrops), while Group B (664 patients) followed the standard protocol alone. In cases of membranous conjunctivitis, manual membrane removal was performed. Treatment responses were observed daily for three days, followed by weekly assessments for two additional weeks.
RESULTS: Co-infection of adenovirus with enterovirus was found to be the main cause, often accompanied by staphylococcal superinfection. Group A showed complete resolution of conjunctival inflammation, with a remarkable 76.05% of patients experiencing improvement within an average of 2.6±0.51 days, in contrast to Group B's average of 7.5±1.1 days (p <0.05). Additionally, 13% of Group B patients with recalcitrant conjunctivitis significantly recovered following the 1% betadine wash. Complications (subconjunctival hemorrhage: 34.04%, superficial punctate keratitis: 6.02%) were more prevalent in Group B.
DISCUSSION: The authors hypothesized that a single wash with betadine is sufficient to reduce disease duration and prevent secondary infections and complications. The core strength of our study lies in…
