Purpose:To report the incidence of endophthalmitis after intravitreal injection of bevacizumab and the outcomes of treatment of endophthalmitis at two centers in Kuwait.Subjects and Methods:The aliquots of bevacizumab were prepared under aseptic precautions and administered in the operating theater on the same day at both centers. All patients received antibiotic drops after injection of bevacizumab. Data were collected on the number of cases that received intravitreal bevacizumab (IVB) and those that developed endophthalmitis were identified at the two centers. All cases of endophthalmitis received an intravitreal antibiotic injection and additional treatments as warranted. Data were collected on the outcomes of endophthalmitis treatment.Results:There were 5 cases of endophthalmitis among a total of 5429 injections (0.09%: Confidence interval: 0.084–0.1). The incidence was 3 cases among 4690 (0.06%) and 2 cases among 739 injections (0.027%) at each center, respectively (P = 0.08). Four cases of endophthalmitis were culture-positive and organisms isolated were, coagulase negative Staphylococcus in 2 cases, Staphylococcus lugdunensis and Streptococcus pneumoniae in 1 case each. The final visual acuity was better than pre-IVB in 3 cases, same as pre-IVB in 1 case and worse in 1 case with streptococcal infection. No eyes developed phthisis bulbi or required enucleation.Conclusions:The incidence of endophthalmitis after intravitreal injection of bevacizumab using aliquots prepared in the operating room is comparable to other studies. There were no clusters of endophthalmitis cases.
Optic disc pit is an excavation of the optic nerve head usually seen in association with other abnormalities of the optic nerve, peripapillary retina, or posterior vitreous detachment. In 50% the cases, it might be associated with serous macular detachment. The prevailing theory that explains this disorder is that subretinal fluid which is derived from liquefied vitreous passes through the optic disc pit and elevates the macula. In this study, we report a case of serous macular detachment complicating optic disc pit in a young male patient treated surgically without internal limiting membrane peeling and showed dramatic improvement of vision after 1 year.
Background:The aim of this study was to compare the effectiveness of pars plana vitrectomy (PPV) and removal of the internal limiting membrane (ILM) with three, monthly, intravitreal bevacizumab (IVB) injections for refractory diabetic macular edema.Materials and Methods:This was a prospective, randomized, comparative, interventional study. Forty-four patients were enrolled and randomized in two groups. Twenty-two eyes enrolled in Group I received three IVB injections at monthly interval. Twenty-two eyes were enrolled in Group II which underwent PPV with ILM removal. The primary outcomes measured were: (1) Best corrected logMAR visual acuity (BCVA) using Snellen's visual acuity chart. (2) Central macular thickness (CMT) on optical coherence tomography. The secondary outcome measures were: Complication rates like (1) progression of lens opacities, (2) high intraocular pressure needing further treatment/procedure, (3) development of vitreous hemorrhage related to the procedure employed, (4) retinal detachment and (5) severe inflammation/endophthalmitis.Results:In Group I (IVB): 3 (13.6%) eyes showed no change in BCVA; 3 (13.6%) eyes reported decrease in BCVA and 16 (72.8%) eyes showed improvement in BCVA; (P = 0.0181). In Group II (PPV): 4 (18.2%) eyes showed no change in BCVA; 5 (22.7%) eyes showed decrease and 13 (59.1%) eyes showed improvement in BCVA (P = 0.0281). Mean decrease in CMT in IVB group was 108.45 μ, whereas mean decrease in CMT in PPV group was 161.36 μ. No major complications were seen in either group.Conclusion:Posttreatment decrease in CMT was more in PPV group and vision improvement more in IVB group. However, no statistically significant difference between the two methods was found.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
