[Morphological basics of scientific research in ophthalmology]

The article summarizes the results of a complex study on lacrimal gland secretion (crystallography), meibomian gland secretion (evaluation of the lipid layer in the intermarginal space of the eyelids) and nasolacrimal contents in dacryostenosis (cytology), and ocular surface condition in conjunctival pathology (impressional cytology). Samples of subretinal tissue (removed during endoscopic surgery in patients with age-related macular degeneration) and corneas (obtained in penetrating mini-keratoplasty performed after previous photorefractive or phototherapeutic keratoplasty) were studied by means of light and electronic microscopy. Engraftment potential of different implants used in orbital plastic surgery was studied experimentally. Data on prenatal development of retinal vascular system and structures responsible for proper ocular hydrodynamics is provided.
