[Perioperative prevention of bleeding in glaucoma surgery]

Area of Science:

• Ophthalmology
• Surgical Innovation

Context:

• Glaucoma surgery, specifically non-penetrating deep sclerectomy, carries risks of postoperative complications.
• Conjunctival hyperemia and hemorrhagic events are common concerns in the early postoperative period.
• Effective preoperative strategies are crucial for optimizing surgical outcomes and patient recovery.

Purpose:

• To evaluate the efficacy of preoperative Oku-Oku eye drops in mitigating conjunctival hyperemia and reducing hemorrhagic complications following glaucoma surgery.
• To assess the impact of Oku-Oku on intraocular pressure (IOP) and scleral vessel coagulation during surgery.

Summary:

• A study involving 30 patients with primary open-angle glaucoma compared the effects of Oku-Oku eye drops versus no additional medication before non-penetrating deep sclerectomy.
• Patients receiving Oku-Oku showed reduced conjunctival hyperemia and a significantly shorter duration of scleral vessel coagulation.
• The incidence of hemorrhagic complications was lower in the Oku-Oku group, although postoperative IOP reduction was similar in both groups.

Impact:

• Preoperative Oku-Oku administration effectively reduces conjunctival hyperemia and scleral vessel width, potentially leading to fewer hemorrhagic complications.
• The findings suggest Oku-Oku can be integrated into preoperative protocols for glaucoma surgery and other procedures prone to bleeding.
• Further investigation is warranted to fully elucidate Oku-Oku's perioperative benefits.
