Investigation Of The Morphometric Structure Of The Retinal Nerve Fiber Layer İn Patients With Chronic Obstructive Pulmonary Disease By Optical Coherence Tomography

Abstract

Aim: To examine the changes in the retinal nerve fiber layer (RNFL) with Spectral-Domain Optical Coherence Tomography (SD-OCT) in individuals diagnosed with Chronic Obstructive Pulmonary Disease (COPD), according to Global Initiative For Chronic Obstructive Lung Disease (GOLD). Materials and Methods: The study consisted of people 18 years or older, including 76 patients with COPD and 80 healthy control groups. Patients with COPD have been examined in four groups A, B, C and D, according to GOLD. RNFL thickness was examined through Optic Nerve Head (ONH) centered in four quadrants; superior, inferior, temporal, and nasal. Results: In the Optic Nerve Head-centered peripapillary area, the RNFL thickness was observed the thinnest in the inferior quadrant in GOLD B, GOLD C, and GOLD D groups (p=0.002). In the temporal quadrant, GOLD A and GOLD C groups were the thickest (p=0.001). Conclusion: The patients with COPD included in our study were divided into groups by evaluating them according to the updated GOLD criteria and we think that this aspect has added richness to the literature. It would be appropriate to consult in terms of eye diseases for the evaluation of retinal functions in COPD patients.
