Aplastic anaemia can manifest as eyelid haematoma, subconjunctival haemorrhage, superficial haemorrhages, preretinal
haemorrhages, vitreous haemorrhages, Roth spots, cotton wool spots and disc oedema.
It's the first reported case of chiropractic care leading to multiple preretinal
hemorrhages, said researchers including Yannis Paulus, a retina specialist at the varsity.
Previously applied laser spots with corresponding preretinal
fibrosis were observed in the temporal periphery.
They found neovascularization in 11 eyes (57.8%), retinal hemorrhages in 10 (52.6%), preretinal
or vitreous hemorrhages in five (26.3%) and these lesions regressed in all cases after a 12-month treatment.
Diagnostic vitrectomy was performed in the right eye, and yellow-white lesions with massive preretinal
hemorrhage were observed in the posterior pole [Figure 1]c.

neovascularization," Experimental Eye Research, vol.
Valsalva retinopathy occurs when the superficial retinal capillaries are ruptured as a result of elevated intraocular venous pressure that occurs following an abrupt increase in intrathoracic or intra-abdominal pressure and usually leads to preretinal
haemorrhage in the macula .
The left eye continued to show iris bombe; therefore, an ocular ultrasound was performed which revealed a retinal detachment and a preretinal
hyperechogenicity suspected to be vitreous hemorrhage, but no evidence of an intraocular tumor.

neovascularization in proliferative diabetic retinopathy using optical coherence tomography angiography," Ophthalmic surgery, lasers and imaging retina, vol.
The newly formed vessels are fragile and easily disrupted by vitreous traction, resulting in hemorrhage in the vitreous cavity or preretinal
High similarity in eye size and preretinal
light transmission characteristics between dogs and humans made this model suitable for examining the genetic and environmental causes of RD diseases.
