Lost Opportunities for Cornea Retrieval: A Cross-sectional Study from District Hospital, Tumakuru, Karnataka

Abstract

Introduction: Corneal blindness in developing countries mainly affects the younger population. About 95% of corneal blindness can be avoided. The economic burden to society is much higher with corneal blindness compared to cataracts. Corneal transplant (Keratoplasty) is the primary vision restoring procedure to rehabilitate patients with corneal blindness. The procedure requires viable corneal tissue. The corneal tissues are procured either by voluntary eye donations or through the Hospital Cornea Retrieval Programme (HCRP). The objective of HCRP is to encourage potential eye donations from hospital deaths by utilising a combined method of motivation and grief counselling. Aim: To find the possibility of cornea retrieval in the district hospital of Tumakuru, Karnataka. Materials and Methods: This cross-sectional study analysed the number of hospital deaths at district hospital, Tumakuru, Karnataka, India, between January 2016 and December 2016. The study was conducted at the same hospital from May 2017 to July 2017. Patient demographics, systemic illnesses, treatment received, and cause of death were obtained from the 757 medical records. Analysis was done for potential corneal donors as per the National Programme for Control of Blindness (NPCB) guidelines. Results: The total number of deaths was 679, which included 375 (55.23%) males and 304 (44.77%) females with maximum death in age group 71-80 years. Of the total deaths, those between 3 and 40 years of age were 196 (28.86%). After excluding the contraindications of cornea retrieval as per NPCB guidelines, 1016 corneas could have been retrieved out of 508 (74.8%) deceased. Conclusion: Hospital cornea retrieval programme can immensely contribute to fill the deficiency of donor corneal tissue. The present study concluded that upto 74.8% of corneas could have been potentially retrieved and indicates a vast potential to reduce the deficit of corneal tissues.
