Bilateral Keratomalacia Secondary to Diet Induced Vitamin A Deficiency in an Ethiopian Young woman: A Case Report

Diet induced vitamin A deficiency is less commonly seen in otherwise healthy adults, due to large store of vitamin A in the body. Night blindness is the commonest manifestation of vitamin A deficiency in adults, whereas Keratomalacia is a rare manifestation. A 27 years old Ethiopian woman came to Jimma University Department of Ohthalmology with a compliant of protrusion of the globe content of both eyes within a week, after having redness and fear of light of both eyes for 2 months. She was a mother of twins and had low socioeconomic status. On general examination, she was cachectic with enlarged parotid glands. On ocular examination, she was bilaterally blind and had dry ocular surface. There was bilaterally melted cornea with prolapsed uveal tissue. After several investigations she was diagnosed as bilateral Keratomalacia (stage X3B) secondary to diet induced vitamin A deficiency. She was supplemented with vitamin A and other nutritional supplementation. Topical lubricating drops and ointments were administered. Finally, conjunctival flap was done to preserve the globe. Although it is rare, treating physicians should be aware of the occurrence of Keratomalacia in adults which is potentially blinding. Early recognition and treatment of vitamin A deficiency at the stage of night blindness is essential in reducing blindness caused by Keratomalacia.
