Area of Science:

Ophthalmology
Surgical Innovation
Retina Surgery

Background:

Vitrectomy is crucial for managing vitreous hemorrhage and other ocular conditions.
Traditional pars plana vitrectomy requires sclerotomies, which can be challenging in certain pediatric cases.
The Eckardt keratoprosthesis (TKP) offers a unique anatomical feature for potential surgical access.

Observation:

A novel limbal vitrectomy technique was performed in a 4-year-old girl with complete hyphema and vitreous hemorrhage.
The procedure utilized pre-existing holes in the Eckardt TKP, avoiding new sclerotomies.
Excellent wide-field visualization of the vitreous cavity and periphery was achieved without scleral depression.

Findings:

Vitrectomy was successfully completed via a limbal approach through the TKP.
Vitreous hemorrhage was evacuated, and the vitreous base was examined.
The procedure involved air-fluid exchange, silicone oil infusion, and TKP replacement with a permanent graft.

Implications:

This technique facilitates limbal vitrectomy in aphakic or non-lens sparing cases using the Eckardt TKP.
It maintains stable intraocular pressure and provides excellent access to the posterior segment.
The method avoids the complexities and potential complications associated with pars plana sclerotomy placement in challenging situations.
