Double optic disc pit maculopathy is a rare entity. It can be difficult to manage because of excessive leakage and chronic maculopathy.
To describe surgical management in a case of double optic disc pits with maculopathy.
A 42-year-old male presented with double optic disc pits with macular detachment in the left eye. The best-corrected visual acuity (BCVA) was 20/60, N12. Preoperative OCT showed the presence of two disc pits. The macular region had large retinoschisis and subretinal fluid (SRF) with a central foveal thickness of 879 microns and loss of the ellipsoid zone. A shallow communication from the temporal aspect of the disc to the submacular area was also noted. Among the options of observation, laser photocoagulation, and surgery, the patient opted for surgical management.
A standard-3 port 23-gauge pars plana vitrectomy was done. After staining the ILM with brilliant blue, ILM peeling was done with the help of forceps and Finesse loop. ILM flaps were inverted over to cover the optic disc pits and sealed with a drop of fibrin glue. Next, 20% SF6 gas was used for tamponade. Pre- and post-surgery parameters such as visual acuity and OCT were evaluated.
After 6 weeks, left eye BCVA was 20/40 with OCT showing reduced SRF and reduced intraretinal schisis with a foveal thickness of 546 microns. At 3 months of follow-up, the vision in the left eye had improved to 20/30 with further reduction in the retinoschisis and foveal thickness of 482 microns.
In this interesting case, we demonstrate a unique way of sealing the defect surgically by vitrectomy and inverted ILM flap with fibrin glue over the disc pits. Despite sealing the maculopathy is slow to resolve.
双眼视盘小凹黄斑病变是一种罕见病症。由于渗漏过多和慢性黄斑病变,其治疗可能具有挑战性。
描述一例双眼视盘小凹伴黄斑病变的手术治疗。
一名42岁男性,左眼患有双眼视盘小凹伴黄斑脱离。最佳矫正视力(BCVA)为20/60,N12。术前光学相干断层扫描(OCT)显示存在两个视盘小凹。黄斑区有较大的视网膜劈裂和视网膜下液(SRF),中央凹厚度为879微米,椭圆体带缺失。还注意到从视盘颞侧至黄斑下区域有浅通道。在观察、激光光凝和手术等选择中,患者选择了手术治疗。
进行了标准的三通道23G经平坦部玻璃体切除术。用亮蓝对内界膜(ILM)进行染色后,借助镊子和Finesse环进行ILM剥除。将ILM瓣翻转以覆盖视盘小凹,并用一滴纤维蛋白胶密封。接下来,使用20%的六氟化硫(SF6)气体进行填塞。评估手术前后的参数,如视力和OCT。
6周后,左眼BCVA为20/40,OCT显示SRF减少,视网膜内劈裂减轻,中央凹厚度为546微米。在随访3个月时,左眼视力提高到20/30,视网膜劈裂进一步减轻,中央凹厚度为482微米。
在这个有趣的病例中,我们展示了一种通过玻璃体切除术和用纤维蛋白胶覆盖视盘小凹的倒置ILM瓣来手术封闭缺损的独特方法。尽管进行了封闭,但黄斑病变的消退仍很缓慢。
