A review of slipped capital femoral epiphysis.

ABSTRACT: Hip pain in children is common, with causes ranging from the benign to destructive. This article reviews slipped capital femoral epiphysis (SCFE), one of the most common hip pathologies in preadolescents and adolescents, which often is missed or delayed in diagnosis because of its vague, atypical presentation.

Postoperative Clinical Outcomes Using Standard Variables Following Levator-Mullerectomy Advancement Blepharoptosis Surgery.

ABSTRACT: The Muller muscle-conjunctival resection is a common technique used to treat blepharoptosis, but there is variability with the target surgical resection and expected postoperative outcomes measured by marginal reflex distance-1 (MRD1). A Levator-Mullerectomy is a novel surgical approach described by Morris et al to incorporate the levator palpebrae superioris in the same incision as the classic Muller muscle-conjunctival resection in the treatment of blepharoptosis. This a retrospective study of patients who underwent Levator-Mullerectomy for ptosis repair showing the clinical outcomes based on MRD1. Statistical analysis was performed using analysis of variance and a nonparametric Kruskal-Wallis test. One hundred-twelve eyes of 83 patients (29 bilateral cases) with a mean age 64.6 years (7-92 years) were included. The types and prevalence of blepharoptosis were involutional (83%), neurogenic (8.0%), traumatic (3.6%), apraxia (2.7%), and congenital (2.7%). There was no significant difference in clinical outcome based on type of blepharoptosis (P = 0.7). Target resection lengths of 8 mm, 10 mm, and 12 mm were compared with postoperative MRD1 change. The mean change in MRD 1 between 8 mm and 10 mm was found to be statistically significant (P = 0.001 for both) but was not statistically significant for the 12 mm resection (P = 0.8). In patients with blepharoptosis and a positive response to 2.5% phenylephrine can benefit from Levator-Mullerectomy with either an 8 mm or 10 mm resection. This novel surgical approach allows surgeons to produce a more predictable and consistent clinical outcome.

Optical coherence tomography angiography in the management of age-related macular degeneration.

PURPOSE OF REVIEW: Optical coherence tomography angiography (OCT-A) provides rapid, flow-based imaging of the retinal and choroidal vasculature in a noninvasive manner. This review contrasts this novel technique with conventional angiography and discusses its current uses and limitations in the management of age-related macular degeneration (AMD). RECENT FINDINGS: Initial work with OCT-A has focused on its ability to identify choriocapillaris flow alterations in dry AMD and to sensitively detect choroidal neovascular membranes (CNVs) in neovascular AMD. Reduced choriocapillaris flow beyond the borders of geographic atrophy seen on OCT-A suggests a primary vascular cause in geographic atrophy. Longitudinal OCT-A analysis of CNV morphology has demonstrated the transition from an immature to mature CNV phenotype following treatment. Current clinical applications of OCT-A include identification of asymptomatic CNV and monitoring for CNV development in the setting of an acquired vitelliform lesion. SUMMARY: OCT-A remains a promising diagnostic tool but one still very much in evolution. Larger studies will be needed to more accurately describe its sensitivity and specificity for CNV detection and to better characterize longitudinal CNV morphologic changes. Anticipated hardware and software updates including swept-source light sources, automated montaging, and manual adjustment of interscan timing should enhance the capabilities of OCT-A in the management of AMD.
