NCT04606056
Intravenous iodinated contrast media is commonly used to enhance diagnostic yield of computer tomography (CT) scans in clinical medicine. However, the perceived risk of contrast-induced nephropathy (CIN) frequently limits its use. While CIN is often self-limiting, it can cause significant morbidity by prolonging admissions and rendering an at-risk individual dialysis dependent. CIN has long been observed and described in clinical studies. There is ample data on CIN after administration of intraarterial contrast, but evidence is less compelling when it comes to intravenous contrast. Increasing studies have called into question the actual risk of intravenous contrast media. Expert panels are suggesting that the risk could have been overstated, leading to contrast being withheld when indicated. There is paucity of local data on this particular issue. More real world data on the actual incidence and risk factors of AKI will be helpful to clinicians. The investigators plan to conduct a single center, retrospective study, to determine the incidence and risk factors of post contrast AKI in contrast enhanced CT scans.

The high success rate of the non-penetrating deep sclerectomy (NPDS) procedure in adult glaucomatous patients motivated some glaucoma specialists to try it as an alternative procedure in childhood PCG. In deep sclerectomy, the surgeon fashions a partial-thickness scleral flap and excises the outer parts of both Schlemm's canal and trabecular meshwork without opening the eye, leaving a thin trabeculo-descemetic membrane. This membrane will guard against early postoperative hypotony due to the non-penetrating nature of the procedure. The aim of this study is to assess the safety and efficacy outcomes of non-penetrating deep sclerectomy versus combined trabeculotomy-trabeculectomy in the treatment of congenital primary glaucoma
