Total eye transplantation for the blind: a challenge for the future

Area of Science:

• Ophthalmology
• Neuroscience
• Regenerative Medicine

Background:

• Blindness represents a significant global health challenge.
• Current treatments for retinal blindness are limited.
• Advancements in prosthetics and grafts offer potential cures.

Purpose of the Study:

• To explore the feasibility of total eye transplantation for curing retinal blindness.
• To propose a surgical paradigm for successful retinal transplantation.

Main Methods:

• Utilizing donor eyes from brain-dead patients with demonstrated retinal viability (via electroretinogram).
• Performing frontoorbitotemporal craniotomy and orbitozygomatic osteotomy for transplantation.
• Employing a specialized guide to channel regenerating optic nerve axons to the lateral geniculate nucleus.
• Implementing protective measures for retinal ganglion cells during axonal regrowth.

Main Results:

• The proposed method outlines a potential surgical approach for eye transplantation.
• The technique addresses optic nerve regeneration and retinal cell protection.

Conclusions:

• Total eye transplantation is a speculative but potentially viable future cure for retinal blindness.
• The proposed paradigm requires further research and development for clinical application.
