Nonarteritic anterior ischemic optic neuropathy following pars plana vitrectomy for macular hole treatment: case report

Nonarteritic Anterior Ischemic Optic Neuropathy following Herpes Zoster Ophthalmicus and Steroid-Related Intraocular Pressure Spike

“…This has been well-described in a number of situations including after ophthalmological procedures, acute glaucoma, hypertensive uveitis, or the administration of steroid eye drops [7][8][9][10][11]. Cases of ophthalmological procedures include cataract extraction complicated by capsular block, pars plana vitrectomy for macular hole, and trabeculectomy complicated by NAION have been described [7][8][9]. NAION after intravitreal injections have also been presumed to be related to elevated intraocular pressure, although the IOP has not been routinely measured in most of these cases [12].…”

“…NAION has been previously described to develop in response to elevated IOP and subsequent disruption to the optic nerve head perfusion pressure [4][5][6]. This has been well-described in a number of situations including after ophthalmological procedures, acute glaucoma, hypertensive uveitis, or the administration of steroid eye drops [7][8][9][10][11]. Cases of ophthalmological procedures include cataract extraction complicated by capsular block, pars plana vitrectomy for macular hole, and trabeculectomy complicated by NAION have been described [7][8][9].…”

A case report of optic neuropathy following dacryocystorhinostomy in a 57-year-old female patient with May-Hegglin anomaly

“…Perioperative vision loss (POVL) is a rare but devastating consequence of ocular or non-ocular surgery. To this end, the nonarteritic anterior ischemic optic neuropathy (NAION) after cataract surgery or PPV has been reported to result from increased intraocular pressure (IOP), raised intra-orbital pressure from a retrobulbar anesthetic, facedown position, systemic peri-operative hypotension, or a combination of these factors [3,4,11,12]. For this reason, the causes of visual impairment in patients undergoing nonocular surgery under general anesthesia can be categorized into three main types: ION, retinal vascular occlusion, and cortical vision loss due to a perioperative stroke.…”

“…However, it is noted that rare complications can occur, including hemorrhage, infection, cerebrospinal fluid leakage, and damage to the medial rectus or superior oblique muscle [2]. Ischemic optic neuropathy (ION) has been documented after a non-complex cataract surgery, uncomplicated pars plana vitrectomy (PPV), and non-ocular surgery, such as with a spinal or cardiac surgery [3][4][5][6]. The retinal arterial occlusion (RAO), cortical blindness, acute glaucoma, and choroidal and vitreous hemorrhage have been reported as causes of perioperative vision loss (POVL) after a non-ophthalmic surgery [7][8][9][10].…”

Does Vitreopapillary Traction Cause Nonarteritic Anterior Ischemic Optic Neuropathy?

“…This is not apparent from the literature review. There are only 3 case reports in the literature of suspected NAION after PPV in which optic disc edema was noted on examination (occurring between postoperative day 5-34) (62,87).…”
