Summary
Acute acquired comitant esotropia (AACE) can be linked to neurological conditions. Early neurological assessment is crucial for diagnosing AACE, especially when accompanied by specific ocular or neurological signs.
Area of Science:
- Ophthalmology
- Neurology
- Pediatrics
Background:
- Acute acquired comitant esotropia (AACE) is a rare condition with sudden onset in older children and adults.
- It presents as a large angle of comitant esotropia with diplopia.
Purpose of the Study:
- To review and summarize current knowledge on neurological pathologies associated with AACE.
- To highlight the importance of neurological assessment in AACE diagnosis.
Main Methods:
- A comprehensive literature survey was conducted using major scientific databases.
- Data from published reports and available literature on neurological pathologies in AACE were collected for a narrative review.
Main Results:
- AACE can have unclear etiologies in both children and adults.
- Functional causes include accommodative spasm and excessive digital screen use.
- AACE is associated with various neurological disorders, including brain tumors, Chiari malformations, intracranial hypertension, and myasthenia gravis.
Conclusions:
- AACE cases with unknown causes occur in children and adults.
- Neurological disorders associated with AACE necessitate neuroimaging.
- Clinicians should perform thorough neurological assessments to exclude pathologies, particularly if nystagmus or other neurological signs are present.

01:17Accessory Structures of the Eye
1.7K
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...

01:25Glaucoma: Overview
648
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...

01:28Angle Closure Glaucoma: Treatment
586
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
504
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.

01:16Focusing of Light in the Eye
3.0K
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...

4.8K
The inner ear assumes dual functionalities of auditory perception and equilibrium maintenance. The vestibule is the organ responsible for balance. This organ contains mechanoreceptors, specifically hair cells, endowed with stereocilia, which aid in deciphering information regarding the position and motion of our heads. Two intrinsic components, the utricle and saccule, help perceive head position, while the semicircular canals track head movement. Neurological messages initiated in the...
