The most common posterior segment finding on ultrasound B-scan in ocular trauma patients is vitreous haemorrhage (33.3%) followed by IOFB (24.6%), retinal detachment (RD) (11.7%), endophthalmitis (7%), globe rupture (7%), traumatic cataract and lens dislocation (4%), traumatic enucleation (0.8%), while choroidal detachments and posterior vitreous detachments were less common findings (table-IV).
No statistically significant differences were observed in creatinine values between individual or between eyes at 0-4 hours and 20-24 hours in vitreous humor as reported earlier (Hanna et al.,1990).
Over time, the collagen fibers degrade and the vitreous gradually liquefies, leading to destabilization of the vitreous gel.
But more impressive flashes or showers of new floaters can indicate that the vitreous has pulled hard enough to tear the retina or detach a portion of this critical tissue from its perch at the back of the eye.
(vii) Phacovitrectomy (Figures 4(a) and 4(b)), vitreous biopsy, and subretinal biopsy (Figure 5) were done for the second eye.
(2) Primary uncomplicated macula-on RRD including PVR grade A or B with one or more contiguous intermediate retinal break(s), defined as breaks between the equator and major vessel arcades [2], and with marked vitreous traction
Ophthalmic examination of PVRL typically reveals mild anterior chamber cells and more prominent vitreous cells with floating clumps.
For symptomatic floaters, three treatment options exist: patient education and observation; vitrectomy (used to remove vitreous gel from the middle of the eye if there is retinal detachment or blood in the vitreous gel) with a one-incision intrector (limited core vitrectomy), and YAG vitreolysis.
If lesion showed increase in size or activity with or without massive vitreous involvement at any time during the follow up visits, focal treatment was abandoned and eyes were either enucleated or EBRT was applied.
