Summary
Severe vision loss after orbital surgery is a serious risk. This review identifies risk factors and anatomical considerations for tumor excisions, decompression, and reconstruction, aiming to improve patient outcomes.
Area of Science:
- Ophthalmology
- Orbitofacial Surgery
- Surgical Complications
Background:
- Vision loss is a significant complication following orbital surgery.
- Understanding risk factors and applied anatomy is crucial for orbitofacial surgeons.
Purpose of the Study:
- To identify risk factors for severe vision loss after orbital surgery.
- To discuss applied anatomy in orbital tumor excisions, decompression, and reconstruction.
Main Methods:
- Literature review using PubMed and Google Scholar.
- Analysis of vision loss cases following orbital tumor surgery, decompression, and trauma reconstruction.
Main Results:
- Incidence of blindness: orbital tumor excisions (4.7%), post-traumatic reconstruction (2.08%), thyroid decompression (0.15%).
- Causes include ischemic/traumatic optic neuropathy, vascular occlusions, and compartment syndrome.
Conclusions:
- Patient selection and risk counseling are vital.
- Preoperative planning, meticulous dissection, and prompt management of complications improve outcomes.

01:25Glaucoma: Overview
1.2K
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...

01:28Angle Closure Glaucoma: Treatment
1.1K
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...

8.6K
At the molecular level, visual signals trigger transformations in photopigment molecules, resulting in changes in the photoreceptor cell's membrane potential. The photon's energy level is denoted by its wavelength, with each specific wavelength of visible light associated with a distinct color. The spectral range of visible light, classified as electromagnetic radiation, spans from 380 to 720 nm. Electromagnetic radiation wavelengths exceeding 720 nm fall under the infrared category,...

01:27Open Angle Glaucoma: Treatment
917
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.
