METHODS: In this randomized clinical trial, 71 eyes of 71 patients scheduled for phaco-emulsification were randomly assigned to two groups: one group (31 eyes) received bolus intracameral adrenaline (1:10,000) and the other group (30 eyes) received adrenaline infusion (1:1,000,000). Pre- and one month postoperatively, a complete ophthalmologic examination as well as endothelial evaluation using ConfoScan III was performed; effective phaco time (EPT) and mydriasis during surgery were also compared between the study groups. RESULTS: The two study groups were not significantly different in terms of demographic characteristics, lens opacity and EPT. Endothelial cell density was 2737±321 cell/mm2 in the bolus group vs 2742±426 cell/mm2 in the infusion group preoperatively (P=0.1). One month postoperatively, the rate of cell loss was 7.21% in the infusion group versus 8.87% in the bolus group (P= 0.13). Pupil diameter was > 6 mm in 48% of eyes in the infusion group vs 33% of eyes in the bolus group (P=0.5). CONCLUSION: Adrenaline was safe at the studied concentrations and there was no significant difference between bolus and infusion routes of administration in terms of pupil dilation and endothelial cell loss.</p> <!--[if gte mso 9]><xml> <w:WordDocument> <w:View>Normal</w:View> <w:Zoom>0</w:Zoom> <w:PunctuationKerning /> <w:ValidateAgainstSchemas /> <w:SaveIfXMLInvalid>false</w:SaveIfXMLInvalid> <w:IgnoreMixedContent>false</w:IgnoreMixedContent> <w:AlwaysShowPlaceholderText>false</w:AlwaysShowPlaceholderText> <w:Compatibility> <w:BreakWrappedTables /> <w:SnapToGridInCell /> <w:WrapTextWithPunct /> <w:UseAsianBreakRules /> <w:DontGrowAutofit /> </w:Compatibility> <w:BrowserLevel>MicrosoftInternetExplorer4</w:BrowserLevel> </w:WordDocument> </xml><![endif]--><!--[if gte mso 9]><xml> <w:LatentStyles DefLockedState="false" LatentStyleCount="156"> </w:LatentStyles> </xml><![endif]--> <!-- /* Font Definitions */ @font-face {font-family:Palatino; mso-font-alt:"Book Antiqua"; mso-font-charset:0; mso-generic-font-family:roman; mso-font-pitch:variable; mso-font-signature:7 0 0 0 147 0;} /* Style Definitions */ p.MsoNormal, li.MsoNormal, div.MsoNormal {mso-style-parent:""; margin:0cm; margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:12.0pt; font-family:"Times New Roman"; mso-fareast-font-family:"Times New Roman";} @page Section1 {size:612.0pt 792.0pt; margin:72.0pt 90.0pt 72.0pt 90.0pt; mso-header-margin:36.0pt; mso-footer-margin:36.0pt; mso-paper-source:0;} div.Section1 {page:Section1;} --> <!--[if gte mso 10]> <style>
