Endoscopic Orbital Decompression for Graves' Orbitopathy - A Vietnam Study

Area of Science:

• Ophthalmology
• Endoscopic Surgery
• Endocrinology

Background:

• Graves' orbitopathy is an autoimmune condition affecting the eye socket.
• Proptosis and compressive optic neuropathy are common, sight-threatening complications.
• Surgical decompression is often necessary to preserve vision and improve aesthetics.

Purpose of the Study:

• To assess the efficacy and safety of endoscopic orbital decompression.
• To evaluate outcomes in patients with Graves' orbitopathy.
• To analyze proptosis reduction and visual function improvements.

Main Methods:

• A prospective study involving 15 patients (28 orbits) undergoing endoscopic orbital decompression.
• Indications included proptosis (22 orbits) and compressive optic neuropathy (6 orbits).
• Outcomes measured: proptosis reduction, visual acuity, visual fields, diplopia, and complications.

Main Results:

• Mean proptosis reduction of 2.23 mm was achieved.
• Significant improvement in visual acuity and visual fields for compressive optic neuropathy.
• One case of intra-operative bleeding, resolved without visual impact; new/worsened diplopia in 4 patients.

Conclusions:

• Endoscopic orbital decompression is an effective and safe surgical option.
• It successfully manages compressive optic neuropathy in Graves' orbitopathy.
• The procedure offers moderate proptosis reduction in the studied population.
