Summary
Surgical clipping effectively treats ophthalmic segment aneurysms (OSAs), despite anatomical challenges. This study shows good outcomes are achievable with careful surgical technique for these complex brain aneurysms.
Area of Science:
- Neurosurgery
- Vascular Neurology
- Cerebrovascular Surgery
Background:
- Ophthalmic segment aneurysms (OSAs) present significant surgical challenges due to complex surrounding anatomy.
- Extensive drilling of the anterior clinoid process and carotid exposure are often required for proximal control.
Purpose of the Study:
- To evaluate the surgical outcomes of ophthalmic segment aneurysms (OSAs).
- To assess the efficacy of surgical clipping as a primary treatment modality for OSAs.
Main Methods:
- Retrospective analysis of 36 OSAs in 35 patients operated by the first author.
- Surgical clipping was the primary treatment, supplemented by wrapping and trapping as needed.
Main Results:
- The most common age group was 40-60 years, with a 3:1 female preponderance.
- 23 patients presented with subarachnoid hemorrhage (WFNS Grade 1); six were asymptomatic.
- Good outcomes (Glasgow Outcome Score) were achieved in 29 patients.
Conclusions:
- Ophthalmic segment aneurysms (OSAs) are technically demanding neurosurgical cases.
- Adherence to surgical principles can lead to favorable outcomes in OSA treatment.

Aneurysm management involves either conservative medical therapy or surgical intervention, depending on the size and symptoms of the aneurysm. Conservative management is generally reserved for smaller, asymptomatic aneurysms, while larger or symptomatic aneurysms often necessitate surgical repair.Conservative Medical TherapyFor small, asymptomatic aneurysms, particularly abdominal aortic aneurysms (AAA) less than 5.5 centimeters in diameter, conservative medical therapy is recommended. This...

01:28Angle Closure Glaucoma: Treatment
887
Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...

01:27Open Angle Glaucoma: Treatment
748
In open-angle glaucoma, the iridocorneal angle remains open, but the trabecular meshwork becomes stiff, slowing down the outflow of aqueous humor. This causes a buildup of aqueous humor in the anterior chamber, leading to a sudden increase in intraocular pressure. The treatment for open-angle glaucoma focuses on reducing the elevated intraocular pressure by either decreasing the secretion of aqueous humor or increasing its outflow.

Vigilant monitoring for aneurysm rupture is essential for patients undergoing aortic surgery.Preoperative Nursing ManagementContinuously monitor the patient for manifestations of aneurysm rupture, such as pallor, weakness, tachycardia, hypotension, abdominal, back, groin, or periumbilical pain, changes in consciousness, and a pulsating abdominal mass. Regularly assess the patient's peripheral pulses.Instruct the patient to consume a clear liquid diet the day before surgery and administer...

01:25Glaucoma: Overview
961
Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...

Thoracic, aortic arch and abdominal aneurysms are significant vascular conditions that can present with various clinical manifestations and lead to serious complications. Understanding these manifestations and the appropriate diagnostic studies is essential for effective management and treatment.Thoracic Aortic AneurysmsThoracic aortic aneurysms often remain asymptomatic until they reach a size that impinges on adjacent structures. They typically cause deep, diffuse chest pain that radiates to...
