Shield ulcer is an uncommon, incapacitating corneal manifestation that occurs in 3-11% of patients suffering from vernal keratoconjunctivitis (VKC). Patients might present with intense itching, sensitivity to light, and “ropy” discharge from the eyes. VKC is a bilateral, seasonal, and external ocular inflammatory disease of unknown cause. Those with VKC frequently have a family or medical history of atopic diseases such as asthma, rhinitis, and eczema. We are presenting a case report of a young male patient who presented with complaints of pain, watering, redness, and photophobia. Slit-lamp examination of the patient revealed an epithelial defect in the right eye that upon further examination was diagnosed to be an epithelial ulcer.

| Introduction|| |
Vernal keratoconjunctivitis (VKC) is a bilateral, seasonal, and external ocular inflammatory disease of unknown cause. Some of the symptoms of VKC include bilateral giant papillae on the tarsal conjunctiva of the upper eyelids, photophobia, mucous discharge, keratopathy, and itching., Shield ulcer is an uncommon, incapacitating corneal manifestation that occurs in 3-11% of patients suffering from VKC. They might present with intense itching, sensitivity to light, and “ropy” discharge from the eyes. Those with VKC frequently have a family or medical history of atopic diseases such as asthma, rhinitis, and eczema. We are presenting a rare case of shield ulcer associated with VKC in a young male patient.
| Case Report|| |
A young male patient aged 25 years came to the ophthalmology department with complaints of pain, watering, redness, and photophobia in right eye for the last 1 month for which he was taking topical antibiotics and using lubricating eyedrops. He had similar complaints of itching, watering, and redness for the last 6 months that used to improve on taking topical antiallergic and using lubricating medications. His best corrected visual acuity was 6/6 in the left eye and 6/18 in the right eye. Slit-lamp examination of both eyes revealed congested conjunctiva, cobblestone appearance of the papillae [Figure 1], and a 3 mm × 2 mm epithelial defect in the superior part of the cornea covered by a lid that stained positive with fluorescein dyes. The ulcer was scrapped and sent for microbiological examination that came negative for acid-fast bacillus (AFB), fungal, and Gram stains. The inferior part of the ulcer had a clear base while the superior half exhibited inflammatory debris and thick plaque. A diagnosis of bilateral VKC with evolving grade 3 shield ulcer in the left eye was made [Figure 2]. Treatment was started with topical steroid eyedrops, mast cell stabilizers, and lubricating eyedrops. After 2 months of taking medication, the ulcer got healed and visual acuity in the right eye was 6/9.
| Discussion|| |
VKC is a chronic, seasonally exacerbated allergic inflammation of the ocular surface involving the tarsal and/or the bulbar conjunctiva. VKC is not a blinding disease but visual impairment is common if the cornea is involved. Although punctate epitheliopathy is the commonest manifestation, shield ulcer with or without plaque, keratoconus, and corneal opacification are not uncommon manifestations of corneal involvement in VKC. The pathogenesis of these ulcers is believed to be mechanical irritation to the corneal epithelium by giant papillae and toxic epitheliopathy from inflammatory mediators secreted by the eosinophils and mast cells. Keratic precipitates in shield ulcer of VKC have not been described to date. Shield ulcer is a severe form of VKC. Various cellular adhesion molecules, including intercellular molecular adhesion-1 (ICAM-1), are increased in the conjunctiva of patients with VKC. Proinflammatory cytokines are upregulated in VKC, which augment the expression of ICAM-1 on the corneal endothelial cells. These proinflammatory cytokines enhance the expression of ICAM-1 that bind to the leukocyte function-associated antigen 1 receptor present on all leukocytes and lead to significant leukocyte adhesion on corneal endothelium. VKC with severe shield ulcer may represent a very aggressive form of inflammatory disease. The shield ulcer plaque should always be debrided and keratic precipitates should be looked for on the corneal endothelium. If present, keratic precipitates may further indicate the severity of disease process.
| Conclusion|| |
Shield ulcer, as a rare complication of VKC, should always be kept in mind for patients suffering from vernal conjunctivitis.
