retinal - Hyperbaric Oxygen


Loss of vision is an extremely rare and unexpected complication following a routine uncomplicated nasal surgery. In majority of patients, visual loss has attributed to retinal emboli which occur with retrograde flow of the intra-arterially injected agents into the nasal cavity or direct trauma to the optic nerve. In this report, the authors present a patient with unilateral decreased vision due to branch retinal artery occlusion soon after a routine nasal surgery. Clinical report. A 32-year-old female patient admitted to the author’ clinic with the complaints of decreased visual acuity in the left eye. She stated that she had undergone rhinoplasty operation 1 week ago and vision loss started immediately after the surgery.In the ophthalmological examination, the best corrected visual acuity with Snellen chart was 1.0 in the right eye and 0.3 in the left eye. In the fundoscopic examination of left eye there was a pale area in the inferior part of the macula. Fundus fluorescein angiography showed no evidence of nonperfusion in the right and left eyes and vascular structure was normal. On the optic coherence tomography, hyperreflectivity and increased thickness were observed in the inner retinal layers of the left eye. In the visual field test, there was a loss of the visual field which corresponds to the pale area on the left eye. Hyperbaric oxygen therapy was recommended. The ophthalmologic examination carried out 2 months later revealed a best corrected visual acuity of the left eye 0.9. In the fundoscopy pale area was regressed in the left eye. Fundus fluorescein angiography showed a good perfusion. There was a little progression in the visual field test. Direct mechanical trauma and vasoplastic/embolic vascular events are thought to be possible mechanisms. The authors think in this case, there was a retrograde flow of agents used during the surgery through ophthalmic artery to retinal arteries and vasospasm by epinephrin worsened the situation. Although rare retinal artery occlusion may develop after rhinoplasty, vision loss as a result of a surgery, if done for aesthetic purposes is not acceptable.
