[Organ of vision in preterm infant].

Examinations of the organ of vision in 79 preterm infants showed lack of sensitivity of the conjunctiva and cornea, unstable precorneal membrane, and insufficient lacrimal production; these features may promote the development of diseases of the anterior segment of the eyeball. Decreased reaction to a light stimulus and lack of the pupil reaction to light are characteristic features of a preterm infant. The position of the baby lying in an incubator and poor transparency of ocular media impedes the ophthalmological examination and require special training of the physician. Pathological changes in the fundus oculi of a preterm baby should be regularly checked up by an oculist during the postnatal period.
