[Persistent hyaloid artery in an adult (a case report)]

The article presents a clinical case of a functioning hyaloid artery in a 69-year-old patient. The results of OCT-angiography made it possible to detect the presence of blood flow in the projection of the persistent hyaloid artery (PHA) on the cross-section and en-face images. The vascular bed of PHA spreading along the posterior surface of the lens in the form of separate branches was visualized by slit-lamp biomicroscopy. The uniqueness of this clinical case lies in the low probability of such findings in the elderly. The presence of a developing cataract indicates the need for an individual approach in determining treatment strategies. In our opinion, the consistent use of laser coagulation technologies and laser photodestruction of PHA will minimize the risk of hemophthalmos and tractional retinal detachment during the upcoming cataract surgery.
