Consequently, knowing the level of awareness of eye donation and willingness among potential donors to donate their eyes after death to ensure availability of donated cornea for transplantation is very crucial. This baseline information is essential for planning towards the establishment of an eye bank. Aim: To determine the level of awareness of eye donation and willingness to donate among patients attending the Eye Clinic at the Korle Bu Teaching Hospital. Study design: Cross-sectional study. Materials and methods: This cross-sectional study was done among 536 eye patients selected by convenient sampling and interviewed using a semi-structured administered questionnaire at the Eye Clinic at the Korle Bu Teaching Hospital. Univariate and multivariate logistic regression were performed at 5% level of significance. Results: Awareness of eye donation and willingness to donate eyes after death were observed in 45 (8.40%) and 321(59.90%) of respondents respectively. Age group 60 and above [AOR = 2.62; CI (0.94-7.31); P=0.04] and education at the professional and tertiary levels [AOR = 4.00 (1.08-14.81); P= 0.03] were possible predictors of awareness of eye donation whilst education was the only predictor of willingness to donate an eye. The main source of awareness of eye donation was through healthcare personals and the media (46.70 %), while the optimal time for eye donation was known by 17.80 % of those who were aware of eye donation. Conclusion: Even though few respondents were aware of eye donation, majority of the respondents were ready to pledge their eyes for donation after death. There is the need for public education on the benefits of eye donation.

The study purposed to determine, from general ophthalmologists at peripheral eye clinics in Ghana, the clinical stage of the disease at presentation to such centres, the challenges associated with its management and to seek recommendations for improvement in the management of retinoblastoma. Methods: A comparative, cross-sectional study was conducted among general ophthalmologists over two time periods: Period 1 (2005-2007) and Period 2 (2014-2016). One ophthalmologist from each peripheral eye clinic in Ghana was interviewed face-to-face, by telephone or email using a structured questionnaire after verbal informed-consent. Results: Responses were received from 24 out of 26 general ophthalmologists in Period 1 and from 35 out of 37 in Period 2. On the average 82 and 95 cases were seen respectively for the two periods. Specifically, 69 cases were seen in the year 2007 and 64 in 2016. The estimated age-specific incidence rates (ASR) for Periods 1 and 2 were 20.3 and 17.3 per million person-years respectively. The common clinical presentations reported by the ophthalmologists were leukocoria followed by proptosis and redness of eyes in both study periods. Diagnosis of retinoblastoma using clinical features supported by imaging (ultrasonography and CT-Scan) was done by 10 out of 24 (41.7%) in Period 1, as compared with 18/35 (51.4%) in Period 2 (p=0.461). Majority of ophthalmologists referred all their patients for treatment elsewhere in both periods on account of lack of resources for management including lack of general anaesthesia. Management challenges included abandonment of treatment by caretakers, lack of resources for management and refusal of treatment by caretakers with reasons such as cost, distance, fear of surgery and fear of bigger hospitals. Recommendations for improvement in management included need for standardized treatment guidelines, early detection through health education and funding for care. Conclusion: Patients with retinoblastoma present with clinically advanced disease to ophthalmologists in peripheral eye clinics in Ghana. There is abandonment and refusal of treatment by caretakers in these centres citing cost and distance as some reasons, and very little improvement over the past decade. Early detection, health education among the general public and health workers, and standardised treatment guidelines are needed to improve on patients' management and survival.
