Objective To evaluate the severity of postoperative inflammation, degree of patient discomfort, adequacy of wound closure, and length of operating time when using fibrin glue compared with sutures to close limbal conjunctival incisions after strabismus surgery. Methods Literature searches of the PubMed and Cochrane Library databases were last conducted on January 24, 2013, and resulted in 24 citations, including 2 not in the English language. All citations were reviewed in full text. Five studies compared fibrin glue (68 eyes) with sutures (74 eyes) for closure of limbal conjunctival incisions in patients undergoing strabismus surgery and were included in this assessment; no studies were found that evaluated fornix incisions. A quality rating was assigned to each study using criteria specifically developed for this assessment. Results No level I studies were found, and 5 level II studies were identified. There was significantly less postoperative inflammation and patient discomfort for 1 to 3 weeks after strabismus surgery for eyes treated with fibrin glue compared with sutures. In 3 studies that evaluated wound apposition, 2 of 50 eyes (4%) with conjunctival incisions that were initially closed using fibrin glue subsequently developed a wound gap that required suture repair. In the 2 studies that compared surgical time, fibrin glue required 1 to 5 minutes less time than suturing in 1 study and 55% less time (3.8 vs. 8.4 minutes) in a second study. These 5 studies did not evaluate the cost-effectiveness or risk of viral transmission from fibrin glue. Conclusions Studies in the literature suggest that the off-label use of fibrin glue to close limbal conjunctival incisions in strabismus surgery resulted in less postoperative inflammation and required shorter operating time compared with sutures, but it increased the percentage of wounds requiring subsequent repair with sutures.

Objective To compare intraocular pressure (IOP) measurements in children 18 years of age and younger using rebound tonometry and applanation tonometry and the feasibility of using these techniques in children. Methods Literature searches of the PubMed and the Cochrane Library databases were last conducted in June 2012 and resulted in 43 citations, including citations not in English. Of these 43 citations, 4 studies met the inclusion criterion following full text review. A level of evidence rating was assigned to each study using criteria specifically developed for this assessment. Results No level I study was found in the literature search, and 2 level II and 2 level III studies were identified. Intraocular pressure was 2 to 3 mmHg higher using rebound tonometry compared with Goldmann applanation tonometry in the 2 level II studies performed in a clinic setting and in 1 level III study performed on children under general anesthesia. However, IOP was lower in 1 level III study in which noncontact applanation tonometry was compared with rebound tonometry. Bland-Altman plots showed that the difference in IOP for rebound versus Goldmann applanation tonometry increased as the IOP increased. The success rate for measuring IOP was markedly higher in children 3 years of age and younger using rebound tonometry compared with noncontact tonometry in 1 level III study. Conclusions Rebound tonometry seems to be a reasonably accurate instrument that allows the IOP to be measured in many children without using general anesthesia. More data are required to assess better how the differences between instruments vary with IOP measurement.

Objective To evaluate the accuracy of detecting clinically significant retinopathy of prematurity (ROP) using wide-angle digital retinal photography. Methods Literature searches of PubMed and the Cochrane Library databases were conducted last on December 7, 2010, and yielded 414 unique citations. The authors assessed these 414 citations and marked 82 that potentially met the inclusion criteria. These 82 studies were reviewed in full text; 28 studies met inclusion criteria. The authors extracted from these studies information about study design, interventions, outcomes, and study quality. After data abstraction, 18 were excluded for study deficiencies or because they were superseded by a more recent publication. The methodologist reviewed the remaining 10 studies and assigned ratings of evidence quality; 7 studies were rated level I evidence and 3 studies were rated level III evidence. Results There is level I evidence from ≥5 studies demonstrating that digital retinal photography has high accuracy for detection of clinically significant ROP. Level III studies have reported high accuracy, without any detectable complications, from real-world operational programs intended to detect clinically significant ROP through remote site interpretation of wide-angle retinal photographs. Conclusions Wide-angle digital retinal photography has the potential to complement standard ROP care. It may provide advantages through objective documentation of clinical examination findings, improved recognition of disease progression by comparing previous photographs, and the creation of image libraries for education and research.

Objective To evaluate the role of cryotherapy in the current treatment of retinopathy of prematurity (ROP). Methods Literature searches of PubMed and the Cochrane Library were conducted on December 2, 2009, for articles published after 1984. The searches included all languages and retrieved 187 relevant citations. Thirteen articles were deemed relevant to the assessment question and were rated according to the strength of evidence. Four articles reported results from 2 large multicenter randomized clinical trials, and the remaining 9 articles reported results of 3 small randomized trials that directly compared cryotherapy and laser. Results Neither of the multicenter randomized clinical trials was a direct comparison of cryotherapy with laser. These studies were used to evaluate the comparative trials based on treatment criteria, study populations, and clinical results. Higher percentages of poor structural and functional outcomes generally were seen in eyes treated with cryotherapy compared with eyes undergoing laser treatment. Higher rates of systemic complications and myopia also were identified after treatment with cryotherapy. Conclusions Despite a relative paucity of level I evidence directly comparing cryotherapy and laser treatment for threshold ROP, the literature suggests that neonatal facilities should gain access to laser technology and laser-trained ophthalmic staff to achieve better outcomes for treatment of the disease.
