The answer is: 1-A; 2-B; 3-F; 4-C; 5-D; 6-E.

Explanation:

1.- Strabismus is an alteration of the binocular vision that occurs when there is a loss of the parallelism of the eyes, that is, when one eye directs the gaze towards a point in space, the other is diverted to a different direction. A)

2.- Glaucoma is an eye disease that steals your vision gradually. In most types of glaucoma, the eye's drainage system is clogged and intraocular fluid cannot drain. When accumulating, it causes an increase in pressure inside the eye that damages the optic nerve that is very sensitive, leading to loss of vision. B)

3.- Commonly called stye is an infection in the eyelid that manifests as a small, red and painful nodule that grows at the base of the eyelashes or inside the eyelid. Most hordeolum are caused by bacterial infections. Internal Hordeolum: Inside the eyelid. It is a product of meibomian gland infection. F)

4.- The cataract is an opacity of the natural (or crystalline) lens of the eye, which is located behind the iris and the pupil. C)

5.- When you have non-proliferative diabetic retinopathy, the walls of the retinal blood vessels weaken. Small lumps (microaneurysms) protrude from the walls of smaller vessels and sometimes spill fluid and blood into the retina. D)  

6.- The macular degeneration consists of a degeneration of the retina, in the area of the macula, the sector of greater visual acuity, whereby the central vision deteriorates. E)
