Summary
Presbyopia, an age-related vision impairment, affects 74.1% of adults in Asmara. This study established new age-based eyeglass prescriptions, highlighting the need for increased access to vision care and tailored guidelines for this population.
Area of Science:
- Ophthalmology
- Public Health
- Optometry
Background:
- Presbyopia is a common age-related condition causing decreased near vision.
- Existing eyeglass prescriptions for presbyopia vary globally.
- No specific data existed for Asmara's population, leading to a high number of uncorrected cases.
Purpose of the Study:
- To determine the age-based eyeglass addition required for presbyopic individuals in Asmara.
- To address the lack of specific data and high prevalence of uncorrected presbyopia in the region.
Main Methods:
- A cross-sectional study involving 1310 participants aged 35-60 in Asmara.
- Near addition was calculated using the Monocular Estimation Method (MEM) and amplitude of accommodation.
- Data analysis was performed using SPSS v. 20.
Main Results:
- The prevalence of presbyopia was 74.1%, with higher rates in females.
- Laborers exhibited the highest prevalence (79.5%), followed by office workers (73%) and housewives (68.7%).
- Older age and female sex were significantly associated with a higher likelihood of presbyopia.
Conclusions:
- A significant proportion of the Asmara population remains uncorrected for presbyopia.
- The required near addition for this population differs from established international standards.
- There is a critical need to improve the availability of eye care services and glasses, alongside developing region-specific guidelines.

01:16Focusing of Light in the Eye
2.9K
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...

01:25Glaucoma: Overview
614
Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...

01:22Photoreceptors and Visual Pathways
6.1K
At the molecular level, visual signals trigger transformations in photopigment molecules, resulting in changes in the photoreceptor cell's membrane potential. The photon's energy level is denoted by its wavelength, with each specific wavelength of visible light associated with a distinct color. The spectral range of visible light, classified as electromagnetic radiation, spans from 380 to 720 nm. Electromagnetic radiation wavelengths exceeding 720 nm fall under the infrared category,...

01:17Accessory Structures of the Eye
1.6K
Optical perception, or vision, is an extraordinary sense dependent on converting light signals received via the ocular organs. These organs, known as eyes, are securely positioned within the bony cavities of the skull, called orbits. The orbits serve a dual purpose: a protective shield for the ocular globes and a stable attachment point for the soft ocular tissues. The eye's external protective mechanisms include the eyelids, which are edged with lashes that act as a barrier against foreign...

01:27Open Angle Glaucoma: Treatment
474
In open-angle glaucoma, the iridocorneal angle remains open, but the trabecular meshwork becomes stiff, slowing down the outflow of aqueous humor. This causes a buildup of aqueous humor in the anterior chamber, leading to a sudden increase in intraocular pressure. The treatment for open-angle glaucoma focuses on reducing the elevated intraocular pressure by either decreasing the secretion of aqueous humor or increasing its outflow.

01:28Angle Closure Glaucoma: Treatment
555
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...
