Reply: Transient retinal artery occlusion during phacoemulsification cataract surgery

Abstract

Sir, Response to 'Primary surgical posterior capsulotomy during phacovitrectomy'We would like to thank Alexander and Luff 1 for their interest in our article. 2 Their described technique for primary surgical capsulotomy during phacovitrectomy is an interesting approach. We find that the ability to remove the anterior hyaloid and visualisation of the fundus during or after phacovitrectomy due to capsular opacification are rarely an issue. When it does later develop, management with Nd:YAG capsulotomy is usually straightforward. Conflict of interestThe authors declare no conflict of interest.

Cotton-wool spots and migraine: a case series of three patients

“…TRAO is a recently proposed clinical entity supported by OCT findings. 2,3 The ERG features of TRAO are yet to be described, and may be sought as part of a prospective case-finding study. Two limitations of Ganzfeld ERG in TRAO are: (1) branch pattern TRAO may not be detected; and (2) b-wave attenuation on ERG reverses fully after 30 min in experimental models of transient retinal ischaemia.…”

“…2 Branch retinal artery occlusion attenuates the N1, P1, and N2 components in the distribution of ischaemic retina on mfERG. 5 mfERG is capable of identifying wider retinal dysfunction than that suggested clinically.…”

“…Isolated CWS are usually asymptomatic although may produce a localised non-arcuate or arcuate scotoma. 1,2 All three patients presented with a new visual disturbance associated with recent migraine. In each case an isolated CWS was identified, corresponding to an area of scotoma.…”

Transient retinal artery occlusion: the potential utility and limitations of electroretinography

“…8 Pattern ERG may also demonstrate reduced amplitude or delayed P50 in cases of macula-involving TRAO, and may have supported a diagnosis in case 1. 2 The mechanism underlying TRAO is unknown. If vasospasm or thromboembolism was responsible, it is conceivable that retinal ischaemia may persist beyond the specific occlusive episode and may be detectable on ERG or mfERG.…”
