Summary
Leber hereditary optic neuropathy (LHON) is a common mitochondrial disease causing vision loss. Recent research explores its genetic causes, particularly in Chinese patients, and potential treatments.
Area of Science:
- Mitochondrial genetics
- Neuro-ophthalmology
- Genetics of rare diseases
Context:
- Leber hereditary optic neuropathy (LHON) is a prevalent mitochondrial disorder.
- It affects young adults, causing painless, rapid vision loss and blindness.
- Over 95% of cases stem from three specific mitochondrial DNA (mtDNA) mutations.
Purpose:
- To review recent advancements in LHON research.
- To focus on molecular mechanisms, clinical aspects, and therapeutic strategies.
- To present findings on genetic susceptibility in Chinese LHON patients.
Summary:
- This review covers LHON's molecular pathogenesis, clinical manifestations, and treatment options.
- It highlights challenges in understanding incomplete penetrance and gender bias.
- Recent studies investigated genetic factors contributing to LHON in a Chinese cohort.
Impact:
- Advances understanding of a common mitochondrial disease.
- Provides insights into genetic susceptibility and disease mechanisms.
- Informs future research on LHON prevention and treatment strategies.

Glaucoma: 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...
Diabetic Retinopathy
DefinitionDiabetic retinopathy is a microvascular complication of diabetes affecting the retinal blood vessels.Risk FactorsDiabetic retinopathy is present in almost all individuals with type 1 diabetes and more than 60% of those with type 2 diabetes after two decades of disease.The risk increases with poor glycemic control, hypertension, dyslipidemia, smoking, pregnancy, and puberty.Although cataracts and glaucoma are also more frequent in people with diabetes, retinopathy remains the leading...
Open 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.
