Key words: Morphological retinal features, fovea, spectral optical coherence tomography, visual acuity, blunt ocular injury.

Introduction: Blunt ocular injury is one of the serious problems in ophthalmology. Purpose: To study morphological retinal features in the fovea based on spectral optical coherence tomography and their correlations with visual acuity in patients with blunt ocular injury.

Material and methods: 43 patients with blunt ocular injury were observed. External nuclear layer, external limiting membrane, ellipsoid of the inner segments of photoreceptors, contact cylinder of cones, pigment retinal epithelium were examined using spectral optical coherence tomography. Their correlations with visual acuity were studied.

Results: We found strong inverse correlations of visual acuity with changes in external limiting membrane (r =—0.89; p= 0.00001), ellipsoid of inner segments of photoreceptors (r=—0.90; p=0.00001), contact cylinder of cones (r= —0.77; p=0.00001), retinal pigment epithelium (r=—0.70; p=0.00001), external nuclear layer (rs =—0.73; p=0.00001).

Conclusion: In the long term period the visual acuity of patients with blunt ocular injury depends on changes of external limiting membrane, ellipsoid of the inner segments of photoreceptors, contact cylinder of cones, retinal pigment epithelium, external nuclear layer.
