It appears to be prudent to use the lowest possible dose of each dye, to minimize the risk of toxic effects. This precaution may be particularly important in the case of BrB, which should not be used in excess of 0.5%. In addition, abundant irrigation of the vitreous cavity after surgery to completely remove traces of dye may be of crucial importance, particularly in the case of ICG, in minimizing chronic toxicity.
RPE tears can occur after intravitreal injection of bevacizumab. The low incidence of this adverse event should not preclude anti-vascular endothelial growth factor therapy counseling for patients with neovascular AMD, but eyes with serous RPE detachments appear to be most vulnerable to this adverse event.
Juvenile X linked retinoschisis (XLRS) is a congenital X linked recessive retinal disorder characterised by cystic maculopathy and peripheral schisis. This study presents the case of an 8-month-old boy with a documented positive family history of XLRS, with a large retinoschisis cavity affecting the macula, first in the left eye and 1 year later in the right eye. The patient underwent pars plana vitrectomy in both eyes using 23-G instruments, posterior hyaloid dissection, a small retinotomy, fluid drainage with a 42-G cannula, infrared diode laser and silicone oil as internal tamponade. The anatomical and functional outcomes at 3 years following the first surgery are described. To the authors' knowledge, there is no previously reported experience with this technique in patients with XLRS.
<P>Postoperative complications of scleral buckling surgery are various. The anterior migration through the rectus muscles and positioning in the corneoscleral junction is an atypical and undocumented complication. The authors describe a patient with a migration and straddling of the encircling buckle in the corneoscleral junction 2 years after a classic retinal surgery with an encircling solid silicone buckle. Many predisposing factors can lead to this situation.
