Background Ranibizumab is widely used in the treatment of macular edema and choroidal neovascularization. Screening should be frequently done to avoid its adverse effect. Materials and methods A prospective noncomparative case series study was conducted at Menoufia and Kalawoon hospitals, where patients were subjected to intravitreal injection of ranibizumab (Lucentis) for early IOP changes. IOP was measured with a Goldman tonometer before injection, after 30 min, after 1 day, and after 1 week of injection. Results At every time of injection, there was a highly significant difference in IOP measured at 30 min after injection (P < 0.001). However, there was no significant difference measured after 1 day (P = 0.91) and after 1 week of injection (P = 0.56). In repeated intravitreal ranibizumab injection comparison of preoperative, 30 min, 1 day, and 1 week after injection correspondingly, we found no significant difference in IOP measured between first and second injection in preoperative, 30 min, 1 day, and 1 week after injection (P = 0.11, 0.36, 0.17, and 0.26, respectively). However, there was a significant difference in IOP measured between first and third injections regarding preoperative, 30 min, 1 day, and 1 week after injection (P = 0.3, 0.2, 0.1, and 0.3, respectively). Conclusion Ranibizumab injected intravitreally causes a significant transient rise of IOP. The rise is transient for 24 h and normalizes after that. }, URL ={http://www.mmj.eg.net/article.asp?issn=1110-2098;year=2019;volume=32;issue=4;spage=1436;epage=1440;aulast=El-Mazar;t=6}, eprint ={http://www.mmj.eg.net/article.asp?issn=1110-2098;year=2019;volume=32;issue=4;spage=1436;epage=1440;aulast=El-Mazar;t=6} }
