Quantitative Analysis of Macular Thickness following Open Globe Injury in Subjects with Clear Media and no Retinal Damage.

Purpose: To evaluate the change in macular thickness after open globe injury (OGI) in patients with clear media and without retinal damage using optical coherence tomography (OCT).

Methods: In this longitudinal observational pilot study, 17 patients with clear media and without retinal damage who underwent repair of OGI for corneal, corneoscleral, or scleral laceration were studied. In addition to routine follow-up, all patients were examined at the first and third postoperative months and best corrected visual acuity (BCVA), slit-lamp examination, applanation tonometry, dilated fundus examinations, and macular OCT scans were documented.

Results: In all patients, no signs of macular edema, macular thickening, cystic changes, or other signs of cystoid macular edema were present in OCT images and examinations. The Early Treatment Diabetic Retinopathy Study map indicated that there were no significant differences in macular thickness between the first and third months in all patients ( P > 0.05). There was no significant relationship between macular thickness and uveal or vitreous prolapse and the size or site of laceration ( P > 0.05). BCVA in the first and third months also showed no significant change ( P > 0.05). There were no cases of intraocular pressure increase in any of the patients.

Conclusion: Macular thickness had no significant change following OGI repair in eyes with clear media and without retinal damage; thus, it seems that OGI of this extent and its surgical repair have no effect on macular thickness.
