Abstract Details


Evaluate the effectiveness of the implementation of vitrectomy with removal of the ILM in the surgical treatment of complicated detachment neuroepithelium optic disc pits.


We operated eight patients (9 eyes) with optic disc pit complicated detachment of the neuroepithelium.


Central vitrectomy 25Ga, mercury light, dosed circular ILM removal with preservation foveolar fragment, air tamponade, without face-down position.


In 7 patients (8 eyes) with optic disc pit complicated detachment neuroepithelium were observed after surgery. According to the dynamic high-definition OCT (8 eyes) - 1 year after surgery, there was a complete resorption of subretinal fluid and foveolar cysts with recovery of visual acuity to 1.0 in two patients. The high visual acuity was due to complete recovery of IS-OS line according to OCT image. During surgery it was found that the entrance of the optic disc pit has a barrier in the form of valves, which work while intraocular pressure changing.


Full recovery of visual acuity in patients with complicated optic nerve pit occurs after removal of the ILM 1 year after surgery. The valve mechanism of the optic disc pit participate in the liquid flow regulation.
