Area of Science:

Ophthalmology
Retinal Surgery

Background:

Choroidal avulsion, a severe complication of ocular trauma, presents significant surgical challenges.
Limited surgical techniques exist for treating extensive choroidal avulsion, particularly after globe rupture.

Purpose of the Study:

To describe and evaluate two novel surgical techniques for treating 360-degree choroidal-ciliary body avulsion following globe rupture.
To assess the efficacy of these techniques in restoring visual acuity.

Main Methods:

Two cases of globe rupture with 360-degree choroidal avulsion were treated.
Surgical interventions included vitrectomy followed by either a mattress suturing technique (10-0 proline) or a single suture technique (7-0 nylon).
A wide-angle viewing system was used to suspend and fix the slipped retina-choroid to the sclera.

Main Results:

Both surgical methods successfully suspended and fixed the slipped retina-choroid to the sclera.
Postoperative improvement in visual acuity was observed in both patients.
The retina remained attached in both cases after the intervention.

Conclusions:

The described mattress suturing and single suture techniques are effective surgical options for managing extensive choroidal avulsion.
These methods offer a viable approach to improve visual outcomes in patients with severe ocular trauma involving choroidal detachment.
