Summary
Orbital cellulitis can precede acute comitant esotropia in children, a rare condition. This case highlights an unusual presentation of esotropia without myositis or neurologic issues.
Area of Science:
- Ophthalmology
- Pediatric Neurology
- Infectious Diseases
Background:
- Acute extraocular muscle restriction in children is uncommon, with orbital myositis being the most frequent etiology.
- Neuropathic or myopathic origins of strabismus typically manifest as incomitant deviations.
Observation:
- A pediatric patient presented with acute comitant esotropia.
- The esotropia was preceded by symptoms of orbital cellulitis.
Findings:
- The patient exhibited no clinical or diagnostic evidence of orbital myositis.
- Neurologic examination and investigations ruled out underlying neurologic pathology.
Implications:
- Orbital cellulitis should be considered in the differential diagnosis of acute comitant esotropia in children.
- This case expands the understanding of potential causes for acute strabismus in pediatric populations.
- Further research may elucidate the pathophysiological link between orbital infections and sudden-onset comitant esotropia.

Angle 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...
Open 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.

Glaucoma: Overview
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...
Accessory 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...
Muscles of the Eye
The muscles of the eye are sophisticated structures that control eye movement and focus, allowing for the precise and rapid adjustments necessary for vision. The human eye is controlled by ten muscles — six extraocular muscles, three intraocular muscles, and one primary eyelid retractor muscle.
Extraocular Muscles
The six extraocular muscles surround the eyeball and control its movements. They are responsible for a wide range of eye motions, including looking up, down, left, right, and rotating...
