Abstract:
Introduction. The bulbar conjunctival microcirculation is a terminal vascular network of the blood vessels
covered by a semi-transparent membrane, located above the white sclera. This easy-to-observe site allows
real-time, in-vivo and non-invasive measurements, which can reveal indicative information about
microvascular function and architecture under different conditions, both physiological and pathological.
Aim of study. The study of microcirculation in the bulbar conjunctiva is an objective and non-invasive
approach, which can be complementary in patients with various pathologies (diabetes, sickle cell anemia,
etc.) to assess the functional and structural adaptation of microcirculation in these pathological conditions.
Methods and materials. A search of the PubMed Central and Google Scholar engines was performed,
using the keywords ,,microcirculation”, ,,bulbar”, ,,conjunctiva”. Only articles in English were selected.
The time period covered was from January 1, 2015 to March 1, 2022.
Results. It is noteworthy that in the last decade there has been substantial progress in the options for
studying and observing microcirculation. Evidence-based medicine has shown that changes in the
microcirculation of the bulbar conjunctiva can be quantified, and can help to monitor systemic pathologies.
It can also be stated that the study of microcirculation can be extensively applied in the investigation of
multiple pathologies to highlight the link between conjunctival microcirculation and systemic pathologies.
Conclusion. Studying the microvascular changes and their correlation with evolutionary aspects of
different pathologies can highlight biomarkers useful for diagnostic or stage evaluation. Taking into account
the accessibility of the method, research in this field will open new perspectives given the currently limited
number of conclusive studies in this field.
