Summary
Occlusion therapy for intermittent exotropia (IXT) in children improved sensory status and fusional amplitudes. While it did not reduce the deviation angle, it may help postpone surgery and enhance surgical outcomes.
Area of Science:
- Ophthalmology
- Pediatric Ophthalmology
Background:
- Intermittent exotropia (IXT) is a common childhood strabismus.
- Effective management strategies are crucial for visual development.
Purpose of the Study:
- To assess occlusion therapy's efficacy for IXT in Saudi Arabian children (4-10 years).
- To emphasize the importance of patching for IXT management.
Main Methods:
- Prospective cohort pilot study involving 21 untreated IXT patients.
- Evaluated deviation angle, amplitudes, stereopsis, and control pre-, during, and post-occlusion therapy.
Main Results:
- 11% showed a 50% decrease in deviation angle.
- 55.5% achieved normal base-out fusional amplitudes.
- 77% demonstrated successful control.
Conclusions:
- Alternate occlusion therapy enhances sensory status and fusional amplitudes.
- Occlusion therapy does not significantly alter the deviation angle.
- It can be a valuable tool to delay surgery and potentially improve surgical outcomes in young children.

01:28Angle Closure Glaucoma: Treatment
1.5K
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
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.

Optical perception, or vision, is an extraordinary sense dependent on converting light signals received via the ocular organs. These organs, known as eyes, are securely positioned within the bony cavities of the skull, called orbits. The orbits serve a dual purpose: a protective shield for the ocular globes and a stable attachment point for the soft ocular tissues. The eye's external protective mechanisms include the eyelids, which are edged with lashes that act as a barrier against foreign...

Ophthalmic drug delivery faces major limitations due to poor absorption across the corneal membrane. This process is primarily driven by diffusion and is influenced by two main factors: the physicochemical properties of the drug and tear drainage. Most ophthalmic drugs, such as pilocarpine, epinephrine, atropine, and local anesthetics, are weak bases. They are typically formulated at an acidic pH to enhance chemical stability. However, this leads to high ionization, reducing their ability to...
