Which condition involves blood collecting under the conjunctiva?

• A. Glaucoma
• B. Subconjunctival Hemmorhage
• C. Retinal Detachment
• D. Night Blindness

Answer: (B)

A subconjunctival hemorrhage is bleeding that happens when one of the tiny vessels under the conjunctiva ruptures. The conjunctiva is the thin membrane covering the white of the eye, and when a vessel breaks, blood leaks into the space between the conjunctiva and the sclera. This produces a bright red patch on the surface of the eye. It often looks dramatic but usually causes no pain and does not affect vision. Common triggers include minor trauma, rubbing the eye, coughing, sneezing, straining, or anything that raises venous pressure. It can also occur with anticoagulant use or bleeding disorders, but many cases occur without any obvious cause. The blood is eventually reabsorbed over about one to two weeks, and no special treatment is needed—cool compresses or simple artificial tears can help with irritation, and you should avoid rubbing the eye. Other conditions mentioned are not characterized by a blood pool under the conjunctiva. Glaucoma involves elevated intraocular pressure affecting the optic nerve and typically presents with eye redness, pain, or vision changes rather than a discrete red patch. Retinal detachment presents with symptoms like sudden vision loss, flashes, or a shadow/curtain over part of the vision. Night blindness refers to difficulty seeing in low light and is a problem of adaptation, not surface bleeding.
