Ocular complications of severe vernal keratoconjunctivitis (VKS ) in Nangarhar province Afghanistan
VKC is a potentially severe, chronic, allergic condition, causing bilateral recurrent inflammatory disorder of the conjunctiva and cornea.
The aim of this study was to assess the ocular complications and visual loss among patients with severe vernal keratoconjunctivitis (VKS).
Material and Methods 481 patients with VKC seen at Department of Ophthalmology Nangerhar university teaching hospital were the study group. This is a retrospective none – comparative observational study between 30/06/2018 and 30/06/2019. Visual acuity was measured with the standard Snellen chart and for children less than 5 years of age Kay pictures were used. Visual impairment was assessed by means of the world health organization criteria, for visual disabilities. Cases with severe VKC that developed ocular complications leading to blindness and severe visual impairment were analyzed.
At the Results the majority of VKC patients were males (75.9%). A total of 76 (15.8%) patients (60 boys and 16 girls) had severe VKC. the ocular findings among 20 patients with severe VKC that led to blindness and severe visual impairment included keratoconus (7) steroid – induced cataract (5) central corneal scars (5) and steroid induced glaucoma (3) two of the keratoconus cases developed acute hydrops.
