METHOD OF PHOTODYNAMIC THERAPY OF POSTERIOR AGGRESSIVE RETINOPATHY IN PREMATURE NEWBORNS Russian patent published in 2012 - IPC A61F9/08 A61K31/409 A61P27/00 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely ophthalmology and may be used for photodynamic therapy of early posterior aggressive retinopathy of premature newborns with no demarcation line and demarcation bar observed. A photosensitiser (PS) 2.0 mg/kg in the form of a herbal porphyrin derivative is introduced orally with baby food in the amount sufficient for single feeding. Thereafter 2 hours later, an avascular retinal area at an extreme periphery is exposed to transconjunctival contact laser light at 3.0 mm from a limb with using a light guide tip at wave length matched to maximum PS adsorption of optical emission. Power density makes 120 J/cm². The exposure covers one line of 15% overlapping spots of the diameter 4 mm in a circle.

EFFECT: invention provides stable regression of posterior aggressive retinopathy in premature newborns with decreased total power of laser exposure covering the retina, reduced length of a laser coagulation session and hence a general anaesthesia care in a premature newborn.
