A solution of perfluorohexyloctane and silicone oil with a specific gravity of 1.06 g/cm 3 (Densiron-68) has similar properties as conventional silicone oil (SO) in terms of the shape of the bubble and its ability to act as an internal tamponade agent. We conducted a case-control study to compare the postoperative intraocular pressure (IOP) in patients treated with Densiron-68 with those treated with SO. Methods Seventy-one eyes of 71 patients and 57 eyes of 57 patients who had received Densiron-68 and SO, respectively, were included in our study. Both groups were found to have matched for their preoperative comorbidities (diabetes, glaucoma, phakic status, and refractive errors). IOP at first day, between seventh and fourteenth day, and at 4 week postoperatively was recorded. Results The mean IOP was higher in patients treated with Densiron-68 at day 1 and between seventh and fourteenth day postoperatively (P ¼ 0.05 and 0.01, respectively). By the 4th week, the IOP difference between the two groups was insignificant (P ¼ 0.17). The difference in the two groups could still be clinically significant and the raised IOP in Densiron-68 group was more difficult to treat in some cases. On day 1, nine eyes (12.7%) in the Densiron-68 group and two eyes (3.5%) in the SO group had IOP greater than 30 mmHg. At 4 weeks, IOP of more than 30 mmHg was seen in nine eyes (12.7%) in the Densiron-68-treated group and in one eye (1.8%) in the SO group. ConclusionThe use of Densiron-68 was associated with a higher IOP in the early postoperative period when compared with SO.

The authors report the case of a 68-year-old woman with secondary adenocarcinoma of the lungs from an unknown primary. Erlotinib was started which produced symptoms suggestive of uveitis. Erlotinib was stopped and restarted a month later at a lower dose, which resulted in severe bilateral anterior uveitis. The uveitis settled after stopping erlotinib and treatment with topical steroids and cycloplegics. To the best of the authors' knowledge, this is the first case of erlotinib-related anterior uveitis.

Aim To evaluate the efficacy of intravitreal bevacizumab in the treatment of retinal vasoproliferative tumours (VPT). Materials and Methods Six eyes of 6 patients with VPT who received intravitreal bevacizumab were retrospectively reviewed. All patients received between one and three injections of intravitreal bevacizumab depending upon response to treatment. Bestcorrected visual acuity (BCVA), tumour size, and presence of co-pathology or sequelae were noted pre-and postoperatively and then analysed. Subsequent retreatments were performed in patients with recurrent or persistent VPT according to the ophthalmologist's discretion. Retreatments included photodynamic therapy with verteporfin, ruthenium-106 plaque brachytherapy, or endoresection of tumour. Results The mean follow-up duration was 33.3 months (range 10-66 months). At baseline, the mean logMAR BCVA was 1.45 (Snellen equivalent of 6/165); range 0.10-1.90
