RB, uveal melanoma research opens door for understanding other cancers
Research in retinoblastoma (RB) and uveal melanoma, two relatively rare ocular cancers, will contribute to all areas of oncology, not just ocular oncology. Discoveries concerning the mechanisms in those two cancers are shedding light on how other tumors function and may aid in the development of therapies and means of predicting metastasis, according to J. William Harbour, MD, who delivered the Cogan Lecture at the annual meeting of the Association for Research in Vision and Ophthalmology.

Capsular tension rings a boon for dealing with weak zonules
Weak zonules can result from a number of different problems, notably, ocular trauma, aging, pseudoexfoliation, or Marfan's syndrome; however, weak zonules can also be associated with retinopathy of prematurity, prior trabeculectomy or vitrectomy, or an ultra-brunescent cataract. The availability of capsular tension rings (CTRs) is a real boon in helping surgeons deal with loose zonules.

Decentered and subluxed IOLs need not be intimidating
Although advancements in IOL designs and management of intraoperative zonular weakness with capsular tension rings have improved our ability to remove cataracts and implant IOLs within the capsular bag successfully, IOL subluxation is still an occasional problem in some patients. Management of these cases may be intimidating but can be easily addressed with a few important principles and simple skills.

What does 'bimanual' surgery really mean?
Reduction of incision size represents only one of many advantages. The crucial difference is not the size of the incision; it is the separation of inflow and outflow.
