Centeral Retinal Artery Occlusion after Viterctomy with Gas Tamponade for Retinal Detachment: A Case Report / 계명의대학술지

ABSTRACT

To introduce a case of Centeral Retinal Artery Occlusion in Gas Tamponade State after Viterctomy for the treatment of Retinal Detachment. A 47-year-old male patient with histories of LASEK surgery 15 years ago and cataract surgery 8 years ago visited our clinic with complaints of sudden visual disturbance in his right eye. He was diagnosed as regmatgenous retinal detachment and underwent pars plana vitrectomy, endolaser photocoagulation, 14% C3F8 gas tamponade, and subtenon triamcinolone injection. After the surgery, the retina was well attached and the visual acuity was improved from finger count 30cm at post-operative day 1 to 0.08 after the 2 weeks of surgery. Intraocular pressure was maintained 20~25 mmHg by Brimonidine/timolol eye drop treatment. The best corrected visual acuity was reduced to hand motion at post-operative day 15. Retinal arteriol attenuation and pale optic disc with 1/3 gas filled vitreous cavity was identified at post-operative day 30. Post-operative 2 years, visual acuity was non light perception with severe narrowing of arteriole and diffuse retinal pigment epithelial atrophy; no retinal vascular flow was observed on fluorescein angiography. Gas tamponade state after viterctomy for the treatment of retinal detachment at high myopia may be risk factors of central retinal artery occlusion.
