Abstract Details
Purpose:
To present the case of a 78 years old man presenting with hand motion visual acuity in his left eye following phacoemulsification under peribulbar anesthesia.
Setting:
University and Polytechnic Hospital la Fe, Valencia, Spain
Methods:
A complete ophthalmological exploration was performed: visual acuity, anterior pole slit lamp examination, posterior pole fundoscopy, retinography, multicolour retinography, autofluorescence retinography, macular B-scan optical coherence tomography (OCT), blood test with haemogram, coagulation, C reactive protein, erythrocyte sedimentation rate, fibrinogen, supra aortic trunks Doppler sonography, and echocardiogram.
Results:
Cherry red spot macula was observed on the left eye retinography. Macular OCT B-scan revealed perifoveal oedema at the innermost layers of the retina with a central macular thickness of 335 microns. Central retinal artery sonography showed a peak systolic strain rate of 45 cm/s in the right eye and 30 cm/s in the left eye. Treatment was initiated with oral corticosteroids intravitreal anti VEGF and dexamethasone implant. Macular oedema progressed to macular atrophy. There was no improvement of visual acuity.
Conclusions:
The cause of foveal ischemia could not be determined. We believe that a temporary reduction of the blood flow in the central retinal artery due to a temporary increase in the orbital pressure secondary to the peribulbar anesthesia in a predisposed patient may have played a role. Paracentral acute middle maculopathy (PAMM) disease spectrum may also be considered into the differentials.
