Summary
A workshop convened stakeholders to address peripherin 2 (PRPH2)-associated inherited retinal diseases (IRDs). Key findings include understanding PRPH2 biology, identifying therapeutic gaps, and the need for collaboration to develop treatments for PRPH2-related IRDs.
Area of Science:
- Ophthalmology and genetics
- Inherited retinal diseases
- Peripherin 2 (PRPH2) biology
Background:
- Peripherin 2 (PRPH2)-associated inherited retinal diseases (IRDs) are rare and complex.
- Significant heterogeneity exists in clinical presentations and disease progression.
- Understanding PRPH2's function is crucial for developing targeted therapies.
Purpose of the Study:
- To define the knowledge landscape of PRPH2 biology.
- To identify challenges and opportunities in developing treatments for PRPH2-associated IRDs.
- To foster collaboration among patients, clinicians, researchers, and industry.
Main Methods:
- Convened a workshop with diverse stakeholders in March 2023.
- Collected insights through affected individuals' presentations and an online survey.
- Facilitated scientific sessions on PRPH2 pathophysiology and therapeutic strategies.
Main Results:
- PRPH2 is vital for rod and cone outer segment maintenance.
- Existing models are useful but additional ones are needed to study PRPH2 variants.
- Key knowledge gaps include PRPH2 biology, phenotypic diversity, and genotype-phenotype correlations.
- A large-scale natural history study is required for better clinical trial design.
Conclusions:
- Collaboration and communication are essential for advancing PRPH2-associated IRD treatments.
- Addressing identified knowledge and therapeutic gaps will accelerate the development of effective interventions.
- Improving understanding of PRPH2 biology and disease progression is critical for patient benefit.

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...
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.

Angle 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...
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...
