En Face Images Using Ultra-Widefield Optical Coherence Tomography in 2 Cases of Traumatic Hypotony Maculopathy before and after Surgical Intervention.

The aim was to investigate the structural changes of the retina using en face ultra-widefield optical coherence tomography (OCT) images during the treatment of hypotony maculopathy with traumatic cyclodialysis. Case 1 was a 43-year-old male patient with visual crowding in his left eye (metallic wire injury that occurred 3 weeks previously) who was referred to our department. Although best-corrected visual acuity was 20/20 in his left eye on initial evaluation, intraocular pressure was 6 mm Hg. Case 2 was a 20-year-old male patient with visual crowding in his left eye (baseball ball injury that occurred 4 weeks previously) who was referred to our department. Although best-corrected visual acuity was 16/20 in his left eye on initial examination, intraocular pressure was 5 mm Hg. Surgical interventions were performed in both cases. En face ultra-widefield OCT images were able to be used to trace dynamic changes before the intervention and up to 1 year later. The images obtained in these two cases made it possible to confirm the progress from wrinkles on the surface of the retina to normalization of vascular structure and improvement of ellipsoid zone disruption. En face ultra-widefield OCT is useful for monitoring multilayer structures of the retina in hypotony maculopathy cases.
