An Overview on Etiology of Corneal Blindness

September 1, 2021 Medicine and Medical 0

In the Puducherry Union Territory, the goal is to screen for people with corneal blindness, establish the aetiology, and assess the risk factors for corneal blindness.

Materials and Methods: Fifty patients with corneal opacity and clinical visual acuity less than 6/60 were enrolled in this study, ranging in age from five to eighty years. Each patient had a complete medical history that included the aetiology, nature of the injury, previous corneal disease, and ocular surgery. External and slit lamp biomicroscopic examinations were performed to determine the size, location, and depth of corneal opacity, the existence of vascularization or ghost vessels, and the anterior segment disease. The Snellen chart was used to record visual acuity, and an applanation tonometer was used to assess intraocular pressure.

The study population was forty-two years old on average; twenty-seven patients were male and twenty-three were female; seventeen patients had bilateral involvement, nineteen had right eye involvement, and fourteen solely had left eye involvement. Farmers, labourers, students, housewives, masons, and others make up the study population. Twenty-one patients had an infectious origin, fourteen had an injury, and the rest had postsurgical, nutritional, or degenerative reasons.

Infectious keratitis is the most common cause of corneal blindness in this study, with trauma coming in second. Occupation plays a significant role on risk. Corneal blindness can be reduced by raising public awareness and implementing safety measures.
