Hyphema Due to Wound Vascularization After Cataract Extraction

Bilateral intraocular hemorrhage from vascularization of cataract wounds

“…Clinical and histopathological examinations suggest that the abnormal vessels arise from the episclera rather than from the deep scleral plexus. 3,4 Our patient presented with hyphemas in both eyes after vomiting. This Valsalva-type maneuver increases episcleral venous pressure, providing support for an episcleral source for the abnormal vessels in our patient.…”

Cataract surgery outcomes: comparison of the extracapsular cataract extraction and manual small incision cataract surgery techniques

“… 67 The presence of hyphaema was observed in only one participant in the ECCE group and may be due to focal vascularisation of the wound created during surgery. 68 …”

Intravitreal anti-vascular endothelial growth factor injections to treat post-trabeculectomy Swan syndrome

“…Swan syndrome is a rare, late-onset surgical complication that was first described by Kenneth C. Swan in 1973. 1 Frequently overlooked, it consists of recurrent intraocular bleeding months to years after an uncomplicated anterior segment surgery, due to abnormal vessels growth through the incisions.…”

“…It should be considered in either pediatric or adult patients complaining of episodes of painless blurred vision who have a history of anterior segment surgery. Indeed, although it has mostly been reported after either intracapsular or extracapsular cataract surgery, 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 cases following glaucoma filtering procedures have also been described. 8 , 9 , 10 …”

“…Although there are only some case series published, several authors have suggested that the faulty wound closure and gaping of the inner edges of the wound may be contributing factors. 1 , 6 , 8 , 11 , 13 Additionally, it has been demonstrated that the limbal wounds healing process is associated with ingrowth of episcleral tissue and vessels, 8 likely due to poor wound apposition. 1 , 3 , 7 , 8 In fact, postmortem studies suggest that focal abnormal wound vascularization is not rare after a surgery involving scleral incisions.…”
