To review pediatric neuroimaging studies of the head and orbit and the radiation-induced cancer risk associated with computed tomography in light of recent attention to pediatric radioimaging by the US Food and Drug Administration, the National Cancer Institute, pediatricians, and radiologists. ⋯ Information obtained from CT scans of the head and orbit may determine or affect management in the pediatric ophthalmic population. Because of the concern of cancer induced by radiation exposure in children, neuroimaging modalities without radiation exposure, such as magnetic resonance imaging or ultrasound, may be considered. However, when CT is indicated, it is reasonable and acceptable to perform CT of the head and orbit while minimizing the radiation exposure, thereby adhering to the "ALARA" (as low as reasonably achievable) policy recommended by the US Food and Drug Administration. Further studies of the actual radiation dose delivered during pediatric CT of the head and orbit and the true incidence of radiation-induced cancers after scans are warranted.

To investigate outcomes of management of blowout fracture patients evaluating computed tomography (CT) findings and diplopia. ⋯ The clinical manifestations and prognosis of patients were approximately predicted through the analysis of CT on fracture type and number of points of contact of an extraocular muscle to the fracture edge.

Randomized Controlled Trial Comparative Study
Topical gel vs subconjunctival lidocaine for intravitreous injection: a randomized clinical trial.
To determine if topical gel is superior to subconjunctival injection of lidocaine in relieving pain of intravitreous injection of corticosteroid. ⋯ The effective relief of pain with lidocaine for intravitreous injection is independent of its mode of application (gel vs subconjunctival injection).

To evaluate the efficacy of pars plana vitrectomy with infracyanine green (IFCG)-assisted internal limiting membrane peeling for the treatment of idiopathic macular hole. ⋯ This study suggests that IFCG (0.05%) effectively stains the ILM with apparent safety, and that IFCG-assisted peeling of the ILM may be useful in the treatment of idiopathic macular hole.

To evaluate the efficacy and safety of apraclonidine 0.5% in the diagnosis of Horner syndrome in pediatric patients. ⋯ The application of apraclonidine in pediatric patients is safe and effective in the diagnosis of Horner syndrome. The reversal of anisocoria was more obvious under high (room light on) ambient illumination.
