Out of the 378 records screened, 253 were included for analysis of MRBs and191 patients were included for analysis of PVD,depending on the inclusion criteria. Features of RRD and retinal breaks noted on examination were compared to the status of MRBs and PVD detected during surgery for possible associations.RESULTS: Overall, 27% patients had MRBs. Retinal holes were commonly missed in patients with lattice degeneration while missed retinal tears were associated with presence of complete PVD. Patients operated for cataract surgery were significantly associated with MRBs(P =0.033) with the odds of missing a retinal break being1.91 as compared to patients with natural lens. Advanced proliferative vitreo retinopathy(PVR) and retinal bullae were the most common reasons for missing a retinal break during examination. PVD was present in 52% of the cases and was wrongly assessed in 16%. Retinal bullae,pseudophakia/aphakia, myopia, and horse shoe retinal tears were strongly associated with presence of PVD.Traumatic RRDs were rarely associated with PVD. CONCLUSION: Pseudophakic patients, and patients with retinal bullae or advanced PVR should be carefully screened for MRBs. Though Weiss ring is a good indicator of PVD, it may still be over diagnosed in some cases. PVD is associated with retinal bullae and pseudophakia, and inversely with traumatic RRD.展开更多

The ocular ultrasound was performed gently over closed eyelids.RESULTS: Posttraumatic globe injuries were the most common indication for posterior segment evaluation, which constituted 80(65.57%) eyes. Among these 52 patients had an anechoic posterior segment and 28 patients had variable findings such as vitreous haemorrhage(8.19%), retinal detachment(6.55%), choroidal detachment(4.91%), posteriorly dislocated clear lens(0.81%) and retained intraocular foreign body(5.73%). Non-traumatic cases constituted around 42(34.42%) eyes, which included corneal ulcer(7.37%), retinoblastoma(6.55%), endophthalmitis(4.91%), extraocular muscle cysticercosis(4.91%), orbital cellulitis(4.09%), periocular haemorrhage(2.45%), proptosis(1.63%), paediatric cataract(1.63%) and cryptophthalmos(0.81%). No adverse events of performing the ultrasound was noted.CONCLUSION: First point ultrasonography in paediatric ocular emergencies is a cheap, portable and an effective tool in the assertion of signifi cant posterior segment and orbital diseases.展开更多
