Abstract Details

Purpose:

To report an nonarteritic anterior ischemic optic neuropathy (NAION) after cataract surgery with perioperative increased ocular pressure

Setting:

Kanuni Sultan Suleyman Training and Research Hospital Ophthalmology Department/TURKEY

Methods:

A 46-year-old male patient with a previous diagnose of rheumatoid arthritis underwent bilateral cataract surgery for posterior subcapsular cataract. After the surgery of right eye CDVA was 50/50 and ophthalmic examination was normal. One week after right eye surgery, left eye surgery performed without complication. Perioperative intraocular pressure increased after side port incision and surgery continued after 300 cc % 20 mannitol administration. Postoperative first day CDVA was 10/50; we detected optic disc swelling, leakage on optic disc at late phases on FFA, thickening of the retinal nerve fiber layer and narrowing on visual field detected.

Results:

Three day pulse 1 gr methylprednisolone administrated, and oral methylprednisolone administrated for one month, and dose tapered. CDVA was 20/50 at after three-day 1 gr methylprednisolone treatment, CDVA was 30/50 after one month of surgery.

Conclusions:

The risk of NAION after cataract extraction is low and there is no currently preventative measures to avoid the attack of ischemic optic neuropathy. In this case, we think that there are three risk factors of NAION; increased ocular pressure at the perioperative period, having a crowded optic nerve head with a small cup-disk ratio, diagnosed with rheumatoid arthritis. Therefore, perioperative and postoperative ocular pressure must be attentively managed in patients with risk factors of NAION in order to prevent from NAION.
