To evaluate circumpapillary retinal nerve fiber layer (cpRNFL) and ganglion cell complex (GCC) after ocular blunt trauma.
Best-corrected visual acuity (BCVA), cpRNFL and GCC were evaluated by RTVue-100 OCT in all consecutive patients with previous monocular blunt trauma seen between January 2012 and December 2012.
Twenty-two patients (11 females, 11 males, mean age 43.9 ± 14.2 years) were included in the study. Patients were seen after a mean of 8.42 ± 13.3 (range, 0.08-55.3) years from ocular blunt trauma. BCVA was normal in 11 cases and was less than 0.4 LogMAR in all cases. In 9/22 patients (40.9%), cpRNFL and GCC were reduced, whereas in one case an isolated reduction of GCC with normal cpRNFL was present. In patients with reduction of cpRNFL and GCC, mean BCVA was 0.17 ± 0.17 LogMAR. In 6/9 patients (66.6%) with cpRNFL and GCC reduction, BCVA was ≤ 0.1 LogMAR.
cpRNFL and GCC reduction may be present after ocular blunt trauma and may be associated with preserved visual acuity.
评估眼钝挫伤后周边视网膜神经纤维层（cpRNFL）和节细胞复合体（GCC）的情况。
对 2012 年 1 月至 12 月期间因单眼钝挫伤就诊的所有连续患者，采用 RTVue-100 OCT 检查最佳矫正视力（BCVA）、cpRNFL 和 GCC。
22 例患者（11 例女性，11 例男性，平均年龄 43.9±14.2 岁）纳入研究。患者自眼钝挫伤后平均 8.42±13.3 年（范围 0.08-55.3 年）就诊。11 例患者的 BCVA 正常，所有患者的 BCVA 均低于 0.4 LogMAR。在 22 例患者中，有 9 例（40.9%）cpRNFL 和 GCC 减少，1 例存在孤立的 GCC 减少而 cpRNFL 正常。在 cpRNFL 和 GCC 减少的患者中，平均 BCVA 为 0.17±0.17 LogMAR。在 6/9 例（66.6%）cpRNFL 和 GCC 减少的患者中，BCVA 小于或等于 0.1 LogMAR。
眼钝挫伤后可能出现 cpRNFL 和 GCC 减少，且可能与保留的视力相关。
