In this report, we describe a case of timely gas vitrectomy to displace a moderate submacular hemorrhage from the submacular space without tPA, release vitreoretinal traction along the borders of a posterior retinal tear, and analyze postoperative multimodal imaging findings in a 34-year-old male patient whose right eye was injured by a stone. The patient underwent a successful nontissue plasminogen activator gas vitrectomy 3 days after the accident. A multimodal evaluation with spectral-domain optical coherence tomography (SD-OCT), 10-2 and 30-2 campimetry, microperimetry, multifocal electroretinography (mfERG), and visual evoked potentials was performed 6 months after the accident. The multimodal imaging tests yielded abnormal foveal SD-OCT patterns, with a fibrous sealed tear in the retinal pigment epithelium. Campimetry showed low levels of retinal sensitivity; microperimetry and mfERG revealed a subnormal retinal response and a reduction in the N1 and P1 wave amplitudes. The visual evoked potential responses were normal. Multidisciplinary examination at 6 months postoperatively revealed a structurally and functionally abnormal macula. The retina remained attached. Our functional findings indicate that submacular hemorrhage should be treated in a timely manner to minimize photoreceptor damage.
