Vitrectomy with ILM peeling and gas tamponade without any additional laser photocoagulation seems to be sufficient for the treatment of optic disc pit maculopathy. Further studies are required to evaluate the above findings, although the implementation of large-series studies remains a challenge due to the rarity of cases with optic disc maculopathy.

Since their introduction by Chang et al. in 1987, perfluorocarbon liquids (PFCLs) have become a useful tool in vitreoretinal surgery. They are synthetic compounds with carbon-fluorine chemical chains that have specific physico-chemical properties, which make them valuable for the intraoperative management of the retina by simplifying vitreoretinal surgical maneuvers in a variety of settings. These maneuvers include retinal detachments associated with proliferative vitreous retinopathy, following penetrating trauma, giant retinal tears, dislocated lenses or lens implants and complications from proliferative diabetic vitreoretinopathy. Purified PFCLs are generally considered to be biologically inert. Despite the stability of PFCLs during vitreoretinal surgery, several studies have indicated that these compounds may be associated with toxicity in ocular tissues. The purpose of this review is to report the use and toxicity of PFCLs in vitreoretinal surgery and to present the latest perspectives on modified PFCLs (hydrofluorocarbon liquids (HFCLs) and HFCL-oligomers).

20G STV is a safe and practical technique for the full spectrum of vitreoretinal surgery. It makes the surgery quicker and is well tolerated by patients.

We present our experience from managing presumed bacterial endophthalmitis with 25 g PPV in patients previously implanted with Boston Kpro, which to the best of our knowledge has not been reported before. Although the number of cases is small to draw accurate conclusions, we have to report that 25 g vitrectomy was performed without significant difficulties and seems to be a useful tool for the management of patients with Kpros requiring vitreoretinal surgery.
