METHOD FOR PREDICTION OF CLINICAL COURSE TYPE OF STAGE 2 OF ACTIVE RETINOPATHY OF PREMATURITY ACCORDING TO ULTRASONIC BIOMICROSCOPY DATA Russian patent published in 2024 - IPC A61B8/10 A61B5/107 A61B3/135 

FIELD: medicine; ophthalmology.

SUBSTANCE: invention can be used to predict the clinical course of stage 2 of active retinopathy of prematurity according to ultrasonic biomicroscopy (UBM). That is ensured by ultrasonic biomicroscopy. On the obtained images of the peripheral parts of the subscleral space, the retina and the vitreoretinal interface in the peripheral parts of the retina are assessed in detail. Length and height of the demarcation shaft are estimated. Favorable clinical course of 2nd stage of active retinopathy is predicted in the presence of a demarcation shaft in the form of a section of retinal prominence into the vitreous body cavity with height of 0.27–0.39 mm, localized in temporal, upper or lower segments with length of 4–8 hour meridians (HM) without signs of involvement of structures of vitreous body in pathological process. Unfavorable clinical course of 2nd stage of active retinopathy with a high risk of the disease progression to 3rd stage is predicted by the presence of at least one of the following signs according to UBM: in the presence of a demarcation shaft in the form of a zone of prominence of the retina into the cavity of the vitreous body with height of 0.42–0.62 mm, having a triangular shape, with length of 6–12 HM; demarcation shaft in the nasal segment, meridians of 2–4 hours for the right eye and 8–10 hours for the left eye, regardless of its height; in the presence of point hyperechoic inclusions on the surface of the retina on the demarcation shaft without signs of changes in the structures of the vitreous body.

EFFECT: invention provides the reliable prediction of the clinical course of the given pathology on the basis of structural disturbances in the peripheral fundus according to UBM data for determining the early management of the patients.
