Summary
A modified vitrectomy technique spares the fovea during internal limiting membrane peeling for myopic foveoschisis, reducing macular hole risk. This approach improves visual acuity and retinal anatomy in patients with high myopia.
Area of Science:
- Ophthalmology
- Retinal Surgery
- Medical Technology
Background:
- Myopic foveoschisis is a rare tractional maculopathy in high myopia patients.
- Posterior hyaloid contraction causes retinal layer splitting.
- Standard internal limiting membrane (ILM) peeling risks macular hole formation.
Observation:
- A modified vitrectomy technique was used in 6 patients with myopic foveoschisis.
- Internal limiting membrane peeling excluded the foveal region.
- Patients underwent pars plana vitrectomy with gas tamponade and face-down positioning.
Findings:
- Mean best-corrected visual acuity improved from 0.87 to 0.60 logMAR.
- Retinal thickness reduced significantly from 799 to 318 micrometers.
- No macular holes developed post-operatively.
Implications:
- Fovea-sparing ILM peeling is a promising surgical option for myopic foveoschisis.
- This technique may lower the incidence of post-operative macular hole.
- Improved foveal anatomy and retinal function are observed.

01:27Open Angle Glaucoma: Treatment
1.1K
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
1.4K
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...
