Purpose: Study to find out relationship between visual acuity and retinal visual line disruption in ocular coherence tomogram (OCT) due to (1) changes in the inner segment and outer segment retinal junction (IS/OS), (2) external limiting membrane (ELM) in the foveal region in ocular blunt injuries and to find out it’s prognostic value.
Materials and Methods: Prospective, observational study conducted on 100 eyes of 100 patients who visited the department of ophthalmology with blunt ocular injuries. Patients with associated pre-existing ocular and systemic diseases were excluded. Refraction was done to know the best corrected visual acuity in logarithm of minimum angle of resolution (log MAR) after regression of anterior segment signs. OCT was done to scan and study macular pathology and visual lines. Integrity of IS/OS junction and ELM were studied and analyzed the relationship with visual acuity to consider for prognostic value.
Result: Statistically significant relation was noted between the visual acuity and disruption of lines at retinal IS/OS junction and ELM (P<0> Conclusion: The retinal visual line disruption can be used as prognostic indication for future vision.].
