Summary
Low vision devices (LVDs) significantly improve near vision for patients with Leber hereditary optic neuropathy (LHON). Rehabilitation and LVDs enhance quality of life for individuals with this optic nerve condition.
Area of Science:
- Ophthalmology
- Neuro-ophthalmology
- Low Vision Rehabilitation
Background:
- Leber hereditary optic neuropathy (LHON) is a genetic condition causing progressive vision loss.
- Effective management strategies are crucial for improving the quality of life for LHON patients.
Purpose of the Study:
- To assess visual acuity improvement in Leber hereditary optic neuropathy (LHON) patients using low vision devices (LVDs).
- To analyze the types of distance and near LVDs prescribed for LHON patients.
Main Methods:
- Retrospective review of 74 Leber hereditary optic neuropathy (LHON) patients from 2016-2019.
- Analysis of electronic medical records for prescribed LVDs and visual acuity outcomes.
- Categorization of patients into age groups (<18, 18-40, >40) to evaluate visual improvement.
Main Results:
- Significant near vision improvement was observed across all age groups with LVDs (P < 0.001 to P < 0.0001).
- The 6x cutaway stand magnifier was the most prescribed near LVD (29.7%).
- Niki CCTV was the most common assistive device (12.2%).
Conclusions:
- Low vision devices (LVDs) and rehabilitation offer substantial benefits for patients with Leber hereditary optic neuropathy (LHON).
- These interventions can significantly enhance the daily lives and visual function of individuals affected by LHON.

Photoreceptors and Visual Pathways
6.2K
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,...

Angle Closure Glaucoma: Treatment
604
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...

Glaucoma: Overview
674
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...

Open Angle Glaucoma: Treatment
516
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.
