ABSTRACT
Objective: to determine the magnitude and types of corneal complications of Vernal Kerato Conjunctivitis [VKC] and their effects on vision
Study design: descriptive case-series
Place and duration: this study was conducted from September 2007 to January 2009 at three institutions in Karachi; Department of Ophthalmology, Dow University of Health Sciences and Civil Hospital, Baqai Medical University Hospital and Sindh Government Qatar Hospital Orangi Town
Methodology: all cases of vernal kerato-conjunctivitis presenting from the different areas of Karachi was included in the study. The diagnosis was made mainly on the basis of history and clinical examination
Results: total 200 patients were examined. Superficial punctate keratitis was the most common corneal complication [46%]. Visual impairment was more pronounced in case of Schield ulcer [16%] and corneal plaques [8%]. Association with keratoconus [13%] was also noted. Corneal opacification [13%] and psuedogerontoxon [4%] were also observed
Conclusion: severe corneal complications of vernal kerato-conjunctivitis [VKC] were observed. Superficial punctate keratitis was the most common. Other complications are potentially serious causing visual impairment
