|September 12, 2012
Summary
Highly myopic patients with low vision can be effectively rehabilitated using optical devices. Maximizing residual vision and assessing fixation locus are key to successful visual rehabilitation outcomes.
Area of Science:
- Ophthalmology
- Low Vision Rehabilitation
- Optical Devices
Background:
- High myopia is a significant cause of low vision.
- Effective rehabilitation strategies are crucial for improving daily visual function in these patients.
- Understanding the relationship between visual impairment cause and rehabilitation success is essential.
Purpose of the Study:
- To compare rehabilitation possibilities, current corrective systems, and prescribed optical devices for highly myopic patients with low vision.
- To analyze rehabilitation outcomes based on the cause of visual impairment.
- To discuss rehabilitation considerations related to specific pathologies in highly myopic individuals.
Main Methods:
- Enrolled 25 highly myopic subjects.
- Evaluated visual acuity and retinal sensitivity using Scanning Laser Ophthalmoscope (SLO) microperimetry.
- Assessed the impact of macular pathology and chorioretinal atrophy on rehabilitation.
Main Results:
- 80% of patients were rehabilitated with monocular optical devices; 20% with binocular devices.
- Good correlation between visual acuity and retinal sensitivity was observed, except in cases of extensive macular atrophy.
- Maximizing residual vision (retinal sensitivity > 10 dB) and a defined fixation locus predicted better rehabilitation outcomes.
Conclusions:
- Careful evaluation of visual acuity, retinal sensitivity, and fixation locus is vital for prescribing optimal optical devices.
- Personalized optical device prescription can significantly reduce the impact of low vision disability.
- Further research into specific pathologies and their effect on rehabilitation is warranted.

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...
01:27Open Angle Glaucoma: Treatment
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.

01:25Glaucoma: Overview
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
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...
