Advancements in Ocular Regenerative Therapies

Area of Science:

• Ophthalmology
• Regenerative Medicine
• Cell Biology

Background:

• Stem cells (SCs) are increasingly explored for treating vision impairments and degenerative eye diseases due to their self-renewal and differentiation capabilities.
• Ocular conditions like age-related macular degeneration (AMD), retinitis pigmentosa (RP), and corneal disorders are targets for stem cell therapies.
• Various stem cell types, including embryonic stem cells (ESCs), induced pluripotent stem cells (iPSCs), and adult stem cells, are investigated for ocular regeneration.

Purpose of the Study:

• To review and systematize recent discoveries on stem cell applications in ophthalmology.
• To highlight the potential of stem cell-based therapies for restoring visual function and repairing damaged ocular tissues.
• To provide a comprehensive overview of stem cell use across multiple eye tissues.

Main Methods:

• Literature review of preclinical studies and early-phase clinical trials.
• Analysis of stem cell differentiation protocols and delivery methods.
• Exploration of stem cell applications in cornea, retina, conjunctiva, iris, trabecular meshwork, lens, ciliary body, sclera, and orbital fat.

Main Results:

• Preclinical and early clinical studies show promising outcomes, with some patients reporting improved vision.
• Stem cells demonstrate potential for regenerating various ocular tissues.
• Identified challenges include optimizing differentiation, ensuring cell safety and viability, and refining delivery techniques.

Conclusions:

• Stem cell therapy is a rapidly advancing field in ophthalmology with significant therapeutic potential.
• Continued research is essential to overcome existing challenges and translate promising findings into effective clinical treatments.
• Systematic reviews are crucial for navigating the expanding body of knowledge in stem cell ophthalmology.
