Summary
Acquired nonaccommodative esotropia (ANAET) is more common in children than congenital esotropia. This form of childhood strabismus, often starting between ages 1-5, rarely links to underlying diseases and shows good surgical outcomes.
Area of Science:
- Ophthalmology
- Pediatric Neurology
- Strabismus Research
Background:
- Acquired nonaccommodative esotropia (ANAET) in children is infrequently reported.
- ANAET is often associated with neurologic or neoplastic disorders.
Purpose of the Study:
- To determine the prevalence of ANAET in a pediatric cohort.
- To describe the clinical characteristics of childhood ANAET.
Main Methods:
- Prospective identification of children (<11 years) with esotropia in a rural Appalachian region (1995-1998).
- Review of age at onset, family history, medical history, ophthalmologic findings, and surgical outcomes for ANAET patients.
Main Results:
- ANAET diagnosed in 10.4% of children with esotropia, higher than congenital esotropia (5.4%).
- Median onset age for ANAET was 31.4 months; mean initial deviation was 24 PD.
- Surgical correction achieved orthotropia (≤8 PD) in 13/14 patients, with 12 demonstrating stereopsis.
Conclusions:
- ANAET is more prevalent than congenital esotropia in this cohort.
- Childhood ANAET typically starts between 1-5 years and is infrequently linked to underlying conditions.
- Early surgical intervention for ANAET improves chances of bifoveal fixation compared to congenital esotropia.

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...
01:17Accessory Structures of the Eye
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...
01:16Focusing of Light in the Eye
Light rays enter the eye through the cornea, a transparent dome-shaped tissue that is the eye's outermost layer. The cornea bends or refracts, light rays traveling to the pupil. The shape of the cornea determines how much of the light is bent and whether the image will be focused correctly on the retina at the back of the eye. Once the light has passed through both refraction layers, it converges into a single focal point onto a small area. This is where photoreceptors start transforming...
