While current management of retinopathy of prematurity (ROP) is well evidenced, the recent Neonatal Oxygenation Prospective Meta-analysis (NeoPROM) oxygen therapy trials, and the Bevacizumab Eliminates the Angiogenic Threat of Retinopathy of Prematurity (BEAT-ROP) trial of intravitreal injection bevacizumab, have reopened debate on optimal management. Early postnatal manipulation of oxygen therapy, nutrition and serum IGF 1 levels may improve early retinal blood vessel development and prevent later severe ROP. While the use of intravitreal injections of antivascular endothelial growth factor (VEGF) agents may appear to be an attractive alternative to laser ablation of the peripheral retina, caution is needed. The optimal choice of agent and dose remain unknown, and suppression of serum VEGF levels might interfere with normal angiogenesis processes in developing tissues. There is a pressing need for good Phase 1 studies of these agents, and safety trials. Source

Emerging data from randomised controlled trials of different pulse oximeter oxygen saturation (SpO2) target ranges shows that higher SpO2 targets are associated with a higher risk of severe retinopathy of prematurity. However, the trials have also shown that higher SpO2 targets are associated with improved survival. In the light of these results and pending the full results for long-term outcome, it is recommended that oxygen saturation targets for preterm infants of gestational age less than 28 weeks at birth should be maintained at or more than 90%. © 2013 Elsevier Inc.

The authors report a novel case of solitary infantile myofibroma originating from the conjunctiva and encroaching over the limbus. This is an observational case report with clinicopathologic correlation. Immunostaining of the lesion was positive for vimentin and smooth muscle actin, and negative for pancytokeratin, desmin, myogenin, EMA, myoglobin, HMB45, and MelanA. To the authors' knowledge, this is the first reported case of myofibroma originating from the conjunctiva and this case highlights the importance of considering myofibromatosis in the differential diagnosis of unusual conjunctival lesions.

Purpose: To describe the predisposing pathology and clinical features of all incident cases of rhegmatogenous retinal detachment (RRD) recruited in Scotland during a 2-year period. Design: Prospective surveillance study of incident cases of RRD. Participants: All incident cases of RRD recruited as part of the Scottish Retinal Detachment Study. Methods: During a 2-year period, we coordinated a comprehensive system in which every case of primary RRD presenting to 1 of 6 vitreoretinal surgical sites in Scotland was examined and approached for study inclusion. Main Outcome Measures: Rhegmatogenous retinal detachment incidence, predisposing features, and clinical characteristics. Results: A total of 1202 cases were recruited. Detailed clinical information was available on 1130 (94%) of cases. By causative break, the proportions of RRD were horseshoe tear (HST) associated with posterior vitreous detachment (PVD) in 86.2%, giant retinal tear (GRT) and PVD in 1.3%, non-PVD round hole (RH) in 4.9%, retinal dialysis in 5.9%, and retinoschisis RRD in 1.6%. One in 10 cases reported significant ocular trauma. One in 5 cases were pseudophakic. Round hole RRD more frequently presented with multiple retinal breaks compared with HST RRD (67.8% vs. 48.7%; P = 0.003). In PVD-associated RRD, 56.1% (95% confidence interval [CI], 53.858.3) of breaks were identified in the superotemporal retina. In non-PVD RRD, 54.6% (95% CI, 47.961.1) of breaks were inferotemporal, followed by superotemporal in 34.9% (95% CI, 28.741.5). Lattice degeneration was present in 18.7% of affected eyes and more common in RH RRD (35.7%) than in HST RRD (19.3%) (P = 0.003). Seven percent reported an affected first-degree relative, and these cases were significantly more myopic than nonfamilial cases. Conclusions: More than 85% of RRD cases are associated with PVD and related tractional tears. Non-PVD RH RRD occurred in younger and more myopic individuals. The majority of cases are caused by more than 1 retinal break, and the macula is affected in more than 50% at presentation. Ocular trauma, previous cataract surgery, family history, and lattice degeneration are important predisposing features.

Aim: s: Coats disease is an uncommon form of retinal telangiectasis. Published case series mostly originate from tertiary referrals centres and may provide a skewed view of disease severity. We conducted a prospective population-based study of Coats disease in the United Kingdom to ascertain the incidence and provide a more representative picture. Methods: The study was conducted through the British Ophthalmological Surveillance Unit. This first paper reports the features at presentation; gender, mode of presentation, visual acuity, anterior and posterior segment findings, amount of retinal exudation, and disease staging. Results: A total of 55 eligible cases of Coats disease were identified giving an estimated population incidence of 0.09 per 100 000 of the population. All cases were unilateral and 85% were male. Mean age at presentation was 146 months (median 96 months). The mean age of diagnosis was markedly different with differing mechanisms of presentation. Cases presenting with leucocoria or strabismus presented early whereas subjective visual loss presented much later. A large proportion of eyes (44%) were blind at diagnosis. The great majority of eyes (71%) had 6 or fewer clock hours of retinal exudation. More severe forms/stages of Coats disease were more common in the youngest patients. Conclusions: Compared with published studies of Coats disease, we have found milder disease severity at presentation. This is most likely because of the population-based nature of our study reflecting the full disease spectrum. A large proportion of eyes with Coats have poor visual acuity and disease severity is worse in younger patients. © 2010 Macmillan Publishers Limited All rights reserved. Source
