Disc haemorrhage (DH) is considered a characteristic sign of glaucoma, but its causative mechanism remains to be determined. We present a case of DH that occurred in association with an enlarged peripapillary intrachoroidal cavitation in a non-glaucomatous eye.
A 35-year-old woman was evaluated for a DH that had been detected during a preoperative examination for myopic refractive surgery. Enhanced depth imaging spectral-domain optical coherence tomography imaging of the optic nerve revealed a peripapillary intrachoroidal cavitation adjacent to the DH. The DH was also present at the 1-year follow-up, but had been completely absorbed at the 2-year follow-up, respectively with an enlargement and shrinkage of the intrachoroidal cavitation and prelaminar tissue schisis. Glaucomatous optic nerve change was not observed during the entire follow-up.
DH can be caused by mechanical damage to capillaries from microscopic changes in peripapillary tissues such as enlargement of the intrachoroidal cavitation, regardless of the presence of glaucoma.
视盘出血(DH)被认为是青光眼的一个特征性体征,但其致病机制仍有待确定。我们报告一例非青光眼眼中发生的DH病例,该病例与视乳头周围脉络膜内空洞扩大有关。
一名35岁女性因近视屈光手术术前检查时发现DH而接受评估。视神经增强深度成像光谱域光学相干断层扫描成像显示,DH附近存在视乳头周围脉络膜内空洞。在1年随访时仍存在DH,但在2年随访时已完全吸收,脉络膜内空洞和板层前组织劈裂分别出现扩大和缩小。在整个随访过程中未观察到青光眼性视神经改变。
无论是否存在青光眼,DH可能是由视乳头周围组织的微观变化(如脉络膜内空洞扩大)对毛细血管造成的机械损伤所致。
