Summary
High myopia, common in Nepal, shows frequent fundus changes like tessellated fundus and peripapillary atrophy. Increased axial length and spherical error are key risk factors for these myopic changes.
Area of Science:
- Ophthalmology
- Public Health
- Medical Research
Background:
- Myopia is a growing global health concern, with prevalence projected to reach 4.7 billion by 2050.
- High myopia (<-5.00 D) increases the risk of irreversible blindness and complications like myopic maculopathy.
- Nepal has a high myopia prevalence (47.16%), necessitating studies on its impact.
Purpose of the Study:
- To assess fundus and optic nerve changes in high myopia among Nepalese individuals.
- To examine the association of these changes with age, gender, axial length, and mean spherical error.
Main Methods:
- A prospective, cross-sectional study involving 98 high myopic eyes (<-5.0 D or axial length ≥26.00 mm).
- Colored Fundus photography was used to evaluate posterior segment and optic disc changes.
- Multinomial logistic regression analyzed axial length and mean spherical error as risk factors.
Main Results:
- Tessellated fundus (57.1%) and peripapillary atrophy (40.8%) were the most common posterior segment changes.
- High myopic features were observed in 45.9% of the studied eyes.
- Increased axial length and mean spherical error were identified as significant risk factors for high myopic changes.
Conclusions:
- Myopic changes, including tessellated fundus and peripapillary atrophy, are frequent in the Nepalese high myopia population.
- Axial length and mean spherical error are significantly associated with the development of these fundus changes.

01:25Glaucoma: Overview
508
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...

01:16Focusing of Light in the Eye
2.5K
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...

01:27Open Angle Glaucoma: Treatment
393
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.

5.7K
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,...

01:28Angle Closure Glaucoma: Treatment
437
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...
