Alteration of Retinal Vessel Diameter of the Patients with Pseudoexfoliation and Optical Coherence Tomography Images

Abstract

ABSTRACT Purpose: The aim of this study was to measure retinal vessel diameter using spectral domain optical coherence tomography (SD-OCT), and to compare patients with unilateral pseudoexfoliation syndrome (PEX) with controls. Materials and Methods: 40 patients with pseudoexfoliation material (40+) eyes and (40−) eyes and 32 healthy controls was included study. Observation of pseudoexfoliative material on the anterior lens capsule or pupillar margin in one or both eyes was set as the diagnostic criteria for PEX. The diameter of superior temporal vein, inferior temporal vein; superior temporal artery and inferior temporal artery were measured by SD-OCT device. Results: when PEX (+) eyes were compared with PEX (−) eyes, a significant decrease was noted in vertical diameter of the arteries, as in the superior nasal artery. In PEX (+) patients the diameter of vascular structures was significantly decreased. Conclusion: We report a relationship between PEX and retinal vessel diameter. Vascular narrowing in the contralateral eye was also seen. Thus detection of this narrowing in the non-PEX eye vessels might be important for diagnosis and prevention of early glaucoma.
