Facial drooping can be associated with which two disorders? (Select All that Apply.)

A) Allergic conjunctivitis: Allergic conjunctivitis typically presents with symptoms such as itching, redness, and watery discharge, but the discharge is usually clear, not thick and sticky. It is caused by an allergic reaction and usually does not involve the white, thick, sticky drainage that is described in the question. Itching is a hallmark symptom, but it doesn't typically cause thick drainage.

B) Cataracts: Cataracts involve clouding of the eye’s lens, leading to blurry vision or difficulty seeing, but they do not cause redness, itching, or thick sticky drainage in the conjunctiva sac. Cataracts are a lens problem, not an issue with the conjunctiva, and would not present with the symptoms described in the question.

C) Bacterial conjunctivitis: Bacterial conjunctivitis is characterized by redness, thick, white or yellowish sticky discharge, and often causes itching or discomfort. The discharge is typically thick and can cause the eyelids to stick together, especially upon waking. This condition matches the symptoms described and is a common eye infection caused by bacteria like Staphylococcus aureus or Streptococcus pneumoniae.

D) Viral conjunctivitis: Viral conjunctivitis also causes redness and watery discharge, but the discharge tends to be thin and watery, not thick and sticky like bacterial conjunctivitis. Viral conjunctivitis often involves symptoms like tearing, irritation, and a more watery, clear discharge, and is typically associated with upper respiratory symptoms. It does not match the description of thick, white, sticky drainage.

A) Diabetic retinopathy: Diabetic retinopathy is a complication of diabetes that affects the blood vessels in the retina. It can lead to vision problems, including blurry vision, floaters, and in advanced stages, vision loss. However, the central vision loss specifically described in the question is more characteristic of macular degeneration, as diabetic retinopathy typically causes peripheral vision loss rather than affecting the center of the visual field.

B) Detached retina: A detached retina occurs when the retina pulls away from its normal position, which can lead to sudden vision changes such as the appearance of floaters, flashes of light, and a shadow or curtain over the vision. While it can result in significant visual impairment, it does not typically cause a black spot in the center of vision. The loss of vision in a detached retina tends to occur in peripheral vision first, not centrally.

C) Macular degeneration: Macular degeneration, specifically age-related macular degeneration (AMD), is the most likely cause of the central vision loss described. It affects the macula, the part of the retina responsible for central vision. As the disease progresses, patients may notice a dark or empty spot in the center of their visual field, which matches the complaint of a "black large spot" in the center of their vision.

D) Glaucoma: Glaucoma is a group of eye diseases that typically cause increased intraocular pressure, leading to damage to the optic nerve and peripheral vision loss. It is more commonly associated with peripheral vision loss, and the central vision is generally preserved until the disease progresses to advanced stages. Therefore, central vision loss is not typically a characteristic symptom of glaucoma.
