Subconjunctival hemorrhage

Subconjunctival hemorrhage refers to bleeding caused by the rupture of small blood vessels beneath the conjunctiva. The blood tends to accumulate in a sheet-like fashion within the subconjunctival tissue, forming bright red or dark red patches under the conjunctiva. It commonly occurs in one eye. It can affect individuals of any age, but is more prevalent in older adults. It is usually asymptomatic, though occasionally there may be a sensation of eye fullness or foreign body sensation.

Lens disease

The lens is a transparent, disc-shaped object located inside the eyeball, and it is one of the main refractive media of the eye. Its primary function is to adjust its shape, which changes the refractive index of light, allowing for clear vision at different distances. With age, the elasticity of the lens gradually decreases, and its accommodative power weakens, leading to presbyopia. Additionally, the lens filters out some ultraviolet light, providing a protective effect on the retina. Common lens diseases include: Lens opacity: This refers to a change in the transparency of the lens, also known as cataracts. Lens subluxation and dislocation: Under normal circumstances, the lens is suspended by the suspensory ligaments from the ciliary body, with its axis almost coinciding with the visual axis. Due to congenital factors, trauma, or disease, damage or rupture of the suspensory ligaments can weaken the suspending force, leading to lens subluxation or partial dislocation. If the suspensory ligaments completely rupture, it can result in complete lens dislocation. The main symptom is decreased vision.
