Summary
Ankylosing spondylitis patients with severe spinal deformities can undergo complex eye surgery. Specialized positioning on an orthopedic table enabled successful cataract extraction and glaucoma surgery in a unique case.
Area of Science:
- Ophthalmology
- Orthopedics
- Surgical Innovation
Background:
- A patient with long-standing ankylosing spondylitis and chronic uveitis required cataract surgery in his only eye.
- Severe spinal deformities, including cervical kyphosis, complicated standard surgical positioning.
Observation:
- Routine surgical positions were not feasible due to the patient's extensive spinal deformities.
- An orthopedic operating table was utilized to achieve a reclined head position of 60 degrees.
Findings:
- Successful combined phacoemulsification (cataract removal) and trabeculectomy (glaucoma surgery) was performed.
- The surgical approach for the surgeon and microscope was unconventional due to patient positioning.
Implications:
- Demonstrates the adaptability of surgical techniques for complex spinal conditions.
- Highlights the importance of specialized equipment in managing challenging ophthalmic cases.
- Offers a potential solution for positioning patients with severe ankylosing spondylitis for ocular surgery.

01:25Glaucoma: Overview
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...
01:27Open Angle Glaucoma: Treatment
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.

01:28Angle Closure Glaucoma: Treatment
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...
