Retinopathy of prematurity stage 4 |
"Scar tissue that forms a continuous sheet coming up from the edge of the vascularized retina. This scar tissue can grow toward the vitreous base/posterior lens capsule resulting in traction, distortion, and even detachment." [ISBN:978-3-319-52190-9] |
Stage 4 can occur after treatment (unlike stages 1-3) and may be accelerated by the absence of vascular endothelial growth factor posttreatment leading to an accelerated cicatricial phase. |

Retinopathy of prematurity plus |
"Venous dilatation and arteriolar tortuosity of the posterior retinal vessels and may later increase in severity to include iris vascular engorgement, poor pupillary dilatation (rigid pupil), and vitreous haze. This definition has been further refined in the later clinical trials in which the diagnosis of plus disease could be made if sufficient vascular dilatation and tortuosity are present in at least 2 quadrants of the eye."

Retinopathy of prematurity pre-plus |
"As vascular abnormalities of the posterior pole that are insufficient for the diagnosis of plus disease but that demonstrate more arterial tortuosity and more venous dilatation than normal." [PMID:16009843] |
Over time, the vessel abnormalities of pre-plus may progress to frank plus disease as the vessels dilate and become more tortuous. {xref="PMID:16009843"} |

Threshold disease is considered to be present when stage 3 retinopathy of prematurity (ROP) is present in either zone I or zone II, with at least 5 continuous or 8 total clock hours of disease, and the presence of plus disease."

Dissociated vertical deviation |
"An incomitant tendency for an occluded eye to elevate and extort which resolves on uncovering." [ISBN-13:978-0199679980] |
Dissociated vertical deviation (DVD) occurs when the level of illumination received by either eye is reduced sufficiently and as a result eye deviates progressively upwards, but reverts to its original position when the level of illumination returns to normally acceptable levels. It may sometimes be so asymmetrical as to be virtually unilateral and is associated with heterotropia usually of early onset. {xref="ISBN-13:978-0199679980", xref="ORCID:0000-0003-0986-4123"} |
