Summary
Vitreopapillary traction causes vision loss due to the vitreous pulling on the optic disc. Surgical separation of the vitreous (posterior vitrectomy) effectively restored vision and anatomy.
Area of Science:
- Ophthalmology
- Retinal Diseases
Background:
- Vitreopapillary traction is an uncommon condition causing optic disc elevation and visual loss.
- It involves strong adhesion and traction of the posterior hyaloid onto the optic disc and peripapillary retina.
Observation:
- An 85-year-old man experienced progressive visual loss and optic disc edema in his left eye over six months.
- Swept-source optical coherence tomography (SS-OCT) showed persistent vitreous strand traction on the optic disc.
- Visual field tests revealed generalized sensitivity loss and enlarged blind spots.
Findings:
- A 25-gauge posterior vitrectomy successfully separated the posterior hyaloid from the optic disc.
- This intervention led to significant anatomical and visual improvements.
Implications:
- SS-OCT is valuable for diagnosing vitreopapillary traction and understanding its mechanism.
- Posterior vitrectomy offers an effective treatment for anatomical and visual recovery in these patients.

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...

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...

01:27Open 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.
