Analysis of eye diseases of patients at Kasungu District Hospital in Malawi was made. Malawi is one of the poorest countries in the world and the health system faces a lot challenges in terms of resources. The study was, therefore, done to understand the burden and distribution of eye diseases in this resource-limited setting. A retrospective study was conducted by extracting data from data registers in the outpatient eye department for the period of May 2015 to June 2016. The data of the reported eye diseases analyzed with variables such as patient gender, eye disease type, patient age and times of the year. There was no association between eye diseases and gender nor with times of the year. However, it was noted that the commonest type of eye disease was conjunctivitis. And, there was strong association of some disease type with age, for example, conjunctivitis was common in young age group while cataract was common in the elderly. It was shown in this study that many of the eye diseases endemic in Africa do generally occur in this selected district as well. However, the analysis presents the possibility of reducing the incidences of many diseases by preventive measures and access to health facilities on time.
Eye diseases affect everyone in the world, what usually differs is disease pattern depending on age, gender, religion and climatic conditions. The distribution of eye diseases and causes of blindness in developing and developed nations often differ [
The common ocular diseases worldwide are cataract, glaucoma, conjunctivitis, corneal ulcers, uveitis, refractive errors, and pterygium. Some studies done in Nigeria and Sudan hospitals showed that cataract was the most common eye disease seconded by conjunctivitis [
The study was conducted at Kasungu District Hospital, in Malawi. Kasungu District Hospital is a Ministry of Health hospital and all the services including eye services are free of charge. The hospital serves a population of about 800,000 people and serves both as a primary and secondary care health facility. The pattern of eye diseases at the hospital is not known neither is there any of such data in Malawi.
The aim of this study was to determine the distribution of eye diseases at Kasungu District Hospital and to compare the findings with previous studies done in other African countries. This information would help policy makers in the district in coming up with better intervention programmes for eye diseases.
This was a retrospective study and involved retrieving data from outpatient eye department registers between 1st May 2015 and 30th June 2016. All clients, regardless of age, who came to the eye department to sick medical attention, were included in the study. The eye department had one optometrist and two ophthalmic clinical technicians (who work like ophthalmologists) during the time the study was conducted. Patients were seen first by ophthalmic clinical technicians then to optometrist if they had any refractive errors or any condition requiring his attention. Assessment of visual acuity and other anterior eye segment was done by Snellen’s chart, slit lamp and torch. Posterior eye segment examination was performed using ophthalmoscope and fundoscopy. After assessment, the clinicians made prescription and dispersed drugs within the department. Documentation of the patient details was done in a hard copy register within the eye department.
The following data elements were extracted from the hard copy register: patient identification, age, gender, diagnosis and date when the patient came to hospital. The data entry and analysis was done using Microsoft excel. Analysis included frequency distribution by age groups, gender and diagnosis.
A total number of 7265 patients were included in the study, out of which 3197 (44%) were males and 4068 (56%) were females (
The most common eye disease was conjunctivitis (51%). This was followed by refractive errors (30%), vernalis (7%) then cataract (3%), the rest contributed by other conditions (
The study showed that females (56%) were more in attendance than males (44%) at the hospital. This was also observed in studies done in Malawi [
More adults (>20 years old) had eye diseases in this study than children. Studies done in Sudan [
Conjunctivitis was the commonest cause of eye disease in our study, seconded by refractive errors. Vernalis and cataract were third and fourth leading causes of eye disease, respectively. Studies done in Ghana [
There was no specific time of the year that a particular eye disease was associated with. And, we did not find any study that had reported on this. In addition, no particular eye disease was more common in a particular gender, This is unlike the study done by Ajaiyeoba [
In conclusion, many of the eye diseases endemic to Africa do generally occur in this selected district as well. It is essential that the district health leadership organizes community education and early treatment to reduce prevalence of these diseases in the community. A more extensive survey would help in coming up with even better information regarding the status of eye disease distribution in the district.
