Summary
This case report details a rare adult-onset cyclic esotropia, a condition with alternating strabismus and normal eye alignment. Successful management was achieved through muscle surgery, highlighting a potential treatment for this intermittent eye misalignment.
Area of Science:
- Ophthalmology
- Neuro-ophthalmology
Background:
- Cyclic esotropia is a rare form of strabismus characterized by alternating periods of manifest deviation and ocular alignment.
- Adult-onset cases are infrequently reported, making their diagnosis and management challenging.
Observation:
- A 37-year-old male with high myopia and amblyopia developed cyclic esotropia post-retinal detachment surgery.
- The patient exhibited a 48-hour cycle of orthotropia followed by constant left esotropia.
- Diagnostic workup including MRI, EMG, EEG, and ocular echography yielded unremarkable results.
Findings:
- The patient's cyclic esotropia was successfully managed with muscle surgery.
- The underlying etiology and pathogenesis of adult-onset cyclic esotropia remain unknown.
Implications:
- Cyclic esotropia should be considered in the differential diagnosis of intermittent strabismus in adults.
- This case underscores the importance of considering surgical intervention for refractory cases of adult-onset cyclic esotropia.

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.

01:25Glaucoma: 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...
01:22Photoreceptors and Visual Pathways
At the molecular level, visual signals trigger transformations in photopigment molecules, resulting in changes in the photoreceptor cell's membrane potential. The photon's energy level is denoted by its wavelength, with each specific wavelength of visible light associated with a distinct color. The spectral range of visible light, classified as electromagnetic radiation, spans from 380 to 720 nm. Electromagnetic radiation wavelengths exceeding 720 nm fall under the infrared category, whereas...
