Hemorrhagic Retinal Macrocysts in Advanced Coats Disease

Asymptomatic bilateral simultaneous rhegmatogenous retinal detachments

“…Haemorrhagic retinal cysts have been described in Advanced Coats disease. 9 Intraretinal macrocysts, demarcation lines, retinal thinning, subretinal fibrosis, and lack of retinal mobility are all signs of a long-standing retinal detachment. The intraretinal macrocysts do not require specific treatment and resolve spontaneously after successful retinal reattachment surgery.…”

Hemorrhagic macular intraretinal macrocyst in long-standing rhegmatogenous retinal detachment

“…Blood in the retinal macrocyst cavity is owing to either rupture of retinal blood vessels lining the macrocyst, bridging retinal vessels over a retinal tear, or peripheral neovascularization. [123] Because the resolution of hemorrhage and collapse of the cyst could happen after successful retinal reattachment, macrocyst could be observed.…”

Retinal detachment with hemorrhagic intraretinal macrocyst clinically presenting as pseudo-choroidal melanoma

“…[1] They can range from 2 to 10 disc diameters in size and occur in 1%–3% of long-standing retinal detachments. [23] Their exact pathogenesis is unknown, but they are believed to arise either due to photoreceptor atrophy secondary to choroidal ischemia or degenerative cystic changes in the outer plexiform layer. [4] These cysts are usually filled with fluid and occasionally with blood.…”
