Summary
This study presents a surgical technique for strabismus with distance-near deviations. Adjustable suture recession of all four horizontal recti muscles effectively reduced disparity and improved ocular alignment.
Area of Science:
- Ophthalmology
- Neuroscience
- Surgical Innovation
Background:
- Strabismus with distance-near deviations involves complex disturbances in the ocular motor system.
- Incomitant strabismus presents challenges in both distance and near visual tasks.
Purpose of the Study:
- To detail the surgical treatment and outcomes for patients with disparate distance-near deviations.
- To evaluate the efficacy of a specific surgical approach for these complex strabismic syndromes.
Main Methods:
- Surgical intervention involved recessing all four horizontal recti muscles in both eyes using adjustable sutures.
- The procedure addressed larger vergence angle deviations first, followed by the smaller angle, using bilateral lateral rectus recession (BLREC) or bilateral medial rectus recession (BMREC).
Main Results:
- All 6 patients experienced a significant reduction in distance-near disparity.
- Post-operative outcomes included increased horizontal comitance, normalized accommodative convergence to accommodation ratios, and elimination of diplopia.
Conclusions:
- Adjustable suture recession of the four horizontal recti muscles is an effective treatment for strabismic syndromes with distance-near disparity.
- This surgical technique offers a viable option for improving binocular vision and reducing visual disturbances in affected patients.

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...
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.
