Automated system for measurement of zone 1 in assessment of severity of retinopathy of prematurity

摘要

An automated method for diagnosing and evaluating severity of retinopathy of prematurity in a retina of a patient is provided that is superior to conventional techniques. A graphical user interface (GUI) is provided for receiving biographical information for the patient creating a patient record in a database via the GUI. A photograph of the retina of the patient is collected and placed in the patient record via the GUI. The photograph is then analyzed to determine vascular distributions within the retina. A zone 1 boundary is assigned to the retina based on a set of threshold levels with respect to the determined vascular distributions. A system for performing the automated method is also provided.

1. An automated method for diagnosing and evaluating severity of retinopathy of prematurity in a retina of a patient, said method comprising:
providing a graphical user interface (GUI); receiving biographical information for the patient creating a patient record in a database via said GUI; receiving at least one photograph of the retina of the patient for placement in said patient record via said GUI; identifying a center of an optical nerve in said at least one photograph of the retina computationally; identifying a macula in said at least one photograph of the retina computationally; analyzing said at least one photograph to determine vascular distributions within the retina; assigning a zone 1 boundary to the retina based on a set of threshold levels with respect to the determined vascular distributions; and displaying said zone 1 boundary on said GUI.
