To investigate the clinical features and prognosis of peripheral occult retinopathy in patients with blunt eye contusion and traumatic lens dislocation.

This study included 72 patients (72 eyes) with ocular contusion combined with traumatic lens dislocation. They received 23G minimally invasive vitrectomy combined with cataract extraction from January 2013 to January 2020 at Liuzhou People's Hospital. According to slit lamp and ultrasound biomicroscopic (UBM) examination results, the patients were divided into either an incomplete dislocation group or a total dislocation group. Peripheral retinopathy in the two groups was intraoperatively recorded in detail, and its clinical characteristics and curative effect were analyzed.

The majority (72.22%) of patients with obtuse eyeball contusion combined with traumatic lens dislocation had peripheral occult retinopathy. The prevalence of peripheral occult retinopathy in the lens incomplete dislocation group was as high as 80.95%, which was significantly higher than that in the lens total dislocation group (60.00%; P＜0.05). Occult retinal tear, retinal degeneration, and retinal hemorrhage were the most common peripheral occult retinopathies in both groups. The postoperative retinal condition of all patients was stable with a good visual prognosis.

Peripheral occult retinopathy often occurs in patients with ocular contusion combined with traumatic lens dislocation. The most common peripheral occult retinopathies are retinal tear, hemorrhage, and pathological degeneration. 23G minimally invasive vitrectomy combined with cataract extraction is an effective treatment with the advantages of less trauma and fewer complications.
