Retrobulbar phenol injection was used as a neurolytic to manage blind chronically painful eyes in ten patients. The cause of the blind painful eye was absolute glaucoma in eight of the ten eyes. We used 1.5mL of 1:15 (6.7%) aqueous phenol solution in each case. None of the patients experienced any pain from the injection. Seven patients obtained complete pain relief after the procedure, and one patient had some improvement. We found a range of duration of pain relief of 4.5 to 48 months (mean, 15 months), which compares favorably with retrobulbar alcohol injection. We believe retrobulbar phenol injection is preferable to alcohol. It has the advantage of being less painful during injection because of its local anesthetic properties.
球后酚注射被用作一种神经溶解剂来治疗10例失明慢性疼痛眼。10只眼中有8只失明疼痛眼的病因是绝对青光眼。我们在每例中使用1.5毫升1:15（6.7%）的酚水溶液。所有患者在注射时均未感到疼痛。7例患者术后疼痛完全缓解，1例患者有所改善。我们发现疼痛缓解的持续时间为4.5至48个月（平均15个月），与球后酒精注射相比效果良好。我们认为球后酚注射比酒精更可取。由于其局部麻醉特性，它在注射时疼痛较小。
