Summary
Refractive errors were common in a Nigerian eye clinic, affecting 26.9% of patients. Presbyopia and astigmatism were the most frequent types, highlighting the need for refractive error correction in eye care.
Area of Science:
- Ophthalmology
- Public Health
Background:
- Refractive errors are a significant cause of visual impairment globally.
- Understanding local patterns of refractive errors is crucial for targeted eye care interventions.
Purpose of the Study:
- To determine the prevalence and patterns of refractive errors at Aminu Kano Teaching Hospital, Kano, Nigeria.
- To analyze the types and distribution of refractive errors among patients attending the eye clinic.
Main Methods:
- Retrospective analysis of patient case folders from January to December 2008.
- Data extraction included age, sex, and refractive error type.
- Refractive errors were categorized based on final subjective refraction following basic eye examination and retinoscopy.
Main Results:
- Refractive errors were diagnosed in 1584 patients (26.9% of clinic attendance).
- Presbyopia (40%) and astigmatism (33%) were the most prevalent refractive errors.
- Myopia (14%), hypermetropia (11%), and aphakia (2%) were also observed, with a slightly higher prevalence in females.
Conclusions:
- Refractive errors represent a substantial burden of disease in the studied eye clinic population.
- Routine identification and correction of refractive errors are essential components of comprehensive eye care services.

01:16Focusing of Light in the Eye
Light rays enter the eye through the cornea, a transparent dome-shaped tissue that is the eye's outermost layer. The cornea bends or refracts, light rays traveling to the pupil. The shape of the cornea determines how much of the light is bent and whether the image will be focused correctly on the retina at the back of the eye. Once the light has passed through both refraction layers, it converges into a single focal point onto a small area. This is where photoreceptors start transforming...
01:28Angle Closure Glaucoma: Treatment
Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...

Accurate diagnosis and effective prevention are critical in managing Acute Kidney Injury (AKI), which is linked to high mortality rates ranging from 10% to 80%. Timely recognition of at-risk patients and careful monitoring can significantly reduce the likelihood of kidney damage.Diagnostic Assessments:The diagnostic process starts with a comprehensive medical history to identify prerenal, intrarenal, and postrenal causes.Prerenal causes, such as dehydration, hypotension, or blood loss, should...
