To evaluate the characteristics of retinal detachments caused by squash ball accidents.
Twenty-six patients had a retinal detachment after a squash ball hit their eyes.
Characteristics of the 26 eyes with retinal detachment were large retinal tears parallel to the corneoscleral limbus located close to the ora serrata usually in the temporal superior fundus quadrant (in 14 [54%] of the 26 eyes) and in the temporal inferior quadrant (in seven eyes [27%]); primarily intact vitreous with a traumatic avulsion of the vitreous base in approximately one half the patients; relatively slow progression of the retinal detachment; and additional damage to the choroid and retinal pigment epithelium in the posterior fundus. The patients were young and did not have severe myopia. Reattachment of the retina was achieved in 22 (85%) of the 26 patients. In 11 patients (42%), visual acuity outcome was 20/40 or better with best correction.
Retinal detachments after squash ball accidents show different characteristics with worse prognosis than do ordinary rhegmatogenous detachments. Protective eyewear should be worn when playing squash.
评估壁球运动导致的视网膜脱离的特征。
26例患者因壁球击中眼睛后发生视网膜脱离。
26只发生视网膜脱离的眼睛的特征为：视网膜大裂孔平行于角巩膜缘，通常位于锯齿缘附近，多在颞上象限（26只眼中有14只[54%]）和颞下象限（7只眼[27%]）；约半数患者主要为玻璃体完整，但玻璃体基底部有外伤性撕脱；视网膜脱离进展相对缓慢；眼底后部脉络膜和视网膜色素上皮有额外损伤。患者较为年轻，且无高度近视。26例患者中有22例（85%）视网膜实现复位。11例患者（42%）经最佳矫正后视力达到20/40或更好。
壁球运动导致的视网膜脱离表现出不同特征，预后比普通孔源性视网膜脱离更差。打壁球时应佩戴防护眼镜。
