Moraxella keratitis: risk factors, presentation, and management

vitreous detachment, while 25 (50%) of the 50 control eyes had posterior vitreous detachment. Posterior vitreous detachment in the present case could be a coincidental finding. Posterior vitreous detachment could have been induced by the arterial occlusion as in an experimental model of retinal artery occlusion (Algvere 1977). Another possibility is traction on the papilla causing the central retinal artery occlusion and relief of the occlusion after posterior vitreous detachment. This last possibility of vitreopapillary traction is similar to cases of peripapillary retinal detachment preceding complete posterior vitreous detachment (Aras et al. 2008) or cases with diabetic tractional papillopathy. The sudden anterior chamber decompression can be complicated by hyphema or decompression retinopathy. The present technique requires patient cooperation and special care by the operator. Additional observations are needed to substantiate the efficacy of maximal paracentesis in CRAO.
