Criteria for improving visual acuity in ischaemic branch retinal vein occlusion using argon laser

Subthreshold Micropulse Photocoagulation for Persistent Macular Edema Secondary to Branch Retinal Vein Occlusion including Best-Corrected Visual Acuity Greater Than 20/40

“…Although most patients with good visual acuity such as BCVA > 20/40 were observed without any intervention in previous studies [1–5, 22, 23] and the results of this study suggest that early intervention with SMDLP may maintain BCVA and reduce macular edema in cases with good visual acuity.…”

“…These patients often complain of reduced vision or metamorphopsia. Conventional laser therapy [1, 5] inevitably results in retinal scarring [6–8] and reduced macular sensitivity [9] in some patients. Thus, in patients with good BCVA (such as >20/40), conventional grid laser therapy seems overly invasive, and thus undesirable.…”

Intravitreal steroids in the management of macular oedema

“…The Branch Retinal Vein Occlusion Study Group (1984) showed that argon laser grid photocoagulation can improve VA in eyes in which BRVO with macular oedema has decreased vision to £ 20 ⁄ 40. This has been confirmed by other studies (Battaglia et al 1999;Maar et al 2004;Zaidi et al 2004). Vitrectomy and arteriovenous adventitial sheathotomy have also been shown to reduce macular oedema (Shah et al 2000;Figueroa et al 2004;Yamaji et al 2004).…”

Inner Retinal Microvasculature Damage Correlates With Outer Retinal Disruption During Remission in Behçet's Posterior Uveitis by Optical Coherence Tomography Angiography

“…The FAZ was larger in the BD subgroup that had experienced more ocular attacks than both the normal group and the BD subgroup of fewer attacks in the deep layer. Enlargement of the FAZ has been reported in various retinal vascular diseases, including diabetic retinopathy, [47][48][49] retinal vein occlusion, 50 and other ischemic conditions. 51 Repeated ocular attacks may aggravate retinal ischemia.…”
