ETIOLOGICAL STUDY OF CORNEAL LESIONS LEADING TO VISUAL IMPAIRMENT IN ADULT PATIENTS AT RURAL HOSPITAL - A DESCRIPTIVE CROSS-SECTIONAL STUDY
Abstract
Corneal diseases are among the major causes of vision loss and blindness in the world today, after cataract, glaucoma, and AMD. The major causes of corneal blindness include corneal ulceration, ocular trauma, bullous keratopathy, keratomalacia, corneal degenerations and dystrophies
Purpose: To know the proportion of different etiologies of corneal lesions leading to visual impairment and its demographic distribution.
Materials and Methods: This was a hospital-based descriptive type of cross-sectional study carried out. 100 patients of >20 years age with corneal lesions and with only corneal lesions having best-corrected visual acuity less than 6/18 who attended the outpatient department of Pravara Rural Hospital, Loni were included. A detailed history of all study patients and best-corrected visual acuity was recorded. Clinical diagnosis of corneal lesions was done based on slit-lamp examination of the anterior segment and posterior segment examination.
Results: The majority of patients were in the middle age group that is 40-60 years, out of which 56% were males and 44% were females. Most of the patients were farmers by occupation (44%). Most of the patients had very poor vision that is 43% of patients had the only perception of light vision while 37% of patients had hand movement close to face vision. Ocular trauma (44%) and Infectious keratitis (27%) were the most common causes of corneal lesions
Conclusion: Ocular trauma and infectious keratitis from the major causes of corneal lesions leading to visual impairment in a rural areas. Continued assessment of the burden of corneal blindness with periodic review of trends may help to effectively plan preventive, promotive and rehabilitative blindness control strategies.
