Concomitant esotropia

Concomitant esotropia is a disorder of eye alignment. Patients with this condition cannot maintain consistent alignment of both eyes when looking at the same object, with one eye excessively deviating towards the nose, resulting in esotropia. The angle of deviation remains constant in all directions of gaze, hence the term "concomitant." This disease is common in children, with some cases even being congenital. Congenital esotropia accounts for 5.4% of all concomitant esotropia cases.

Vitreous hemorrhage

The vitreous humor is an avascular tissue and typically does not bleed. If blood enters the vitreous cavity due to disease, trauma, or other reasons, it is called vitreous hemorrhage. Symptoms include decreased vision, a smoky sensation in front of the eyes, and the perception of floating black spots.

Entropion

Entropion is an eyelid condition characterized by the inward turning of the eyelid margin towards the eyeball. Based on the etiology, entropion can be classified into the following four types: Congenital entropion: Primarily affects infants and young children, with a higher incidence in Asians, often occurring in the medial part of the lower eyelid. It is usually accompanied by other abnormalities, such as tarsal dysgenesis or microphthalmia, and can coexist with congenital epicanthus or lower eyelid epiblepharon. Involutional entropion: The most common type clinically. Primarily seen in elderly individuals, mostly affecting the lower eyelid. Spastic entropion: An acute condition caused by excessive contraction of the orbicularis oculi muscle due to ocular irritation or inflammation. If left untreated, it can develop into persistent entropion. Cicatricial entropion: Primarily caused by scar formation in the posterior lamella of the eyelid due to various reasons. Mild entropion may be asymptomatic, while severe cases can present with conjunctival hyperemia, photophobia, tearing, stinging pain, and blepharospasm.
