Resumen
Este estudio detalla un raro caso de estrabismo fijo en un paciente varón, resultado de complicaciones de un tumor cerebral. La intervención quirúrgica restauró con éxito la alineación casi normal de los ojos.
Área de la Ciencia:
- Oftalmología
- Neurología
- Neuro-oncología
Sus antecedentes:
- Un caso raro de estrabismo fijo se presenta en un hombre de mediana edad con una historia de 12 años de hipotropía-esotropía.
- El paciente tenía un diagnóstico previo y una cirugía para un astrocitoma pilocítico posterior.
Objetivo del estudio:
- Para describir una presentación única del estrabismo fijo.
- Para investigar las causas subyacentes del desajuste ocular del paciente.
- Para informar el manejo quirúrgico y el resultado.
Principales métodos:
- Se realizó una resonancia magnética con contraste del cerebro y la órbita.
- El examen clínico evaluó la alineación ocular y la motilidad.
- La corrección quirúrgica implicó recesión bilateral del recto medial y recesión del recto inferior.
Principales resultados:
- La resonancia magnética reveló ventrículos dilatados, una derivación y una arquitectura distorsionada del cerebro medio.
- No se observó desplazamiento recto ni alargamiento axial.
- Tratamiento quirúrgico alcanzado cerca de la ortotropía.
Conclusiones:
- El estrabismo fijo del paciente probablemente fue causado por daño a los centros verticales de la mirada y la parálisis del sexto nervio debido a la hidrocefalia.
- Esto representa un nuevo caso de estrabismo fijo resultante de la coexistencia de parálisis de la mirada y la parálisis del sexto nervio.

01:28Angle Closure Glaucoma: Treatment
674
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...

01:25Glaucoma: Overview
749
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...

01:27Open Angle Glaucoma: Treatment
561
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.

01:20Muscles of the Eye
1.9K
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...

01:22Sutures of the Skull
7.6K
The human skull is composed of several bones that come together to protect the brain and support the structures of the face. The junctions where these bones meet are called sutures.
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...

01:16Focusing of Light in the Eye
3.2K
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...
