“…Peyman proposed permanent mounting of the light pipe on the vitrophage, 39 whereas another option was to combine the illumination with the irrigation. 40 Caution was to be taken when using such instruments, as it was known that excessive exposure by intraocular fiber optic light could have led to retinal damage.…”

Background: Vitreoretinal surgical techniques have evolved during the last decades because of the development and evolution of pars plana vitrectomy. The introduction of modern vitrectomy is credited to Robert Machemer . The aim of this review is to characterize the early developments of vitreous removal.Methods: We used the PubMed web platform to search the terms: complications of cataract surgery, vitrectomy, vitreous body, vitreous humor, vitreous humour, vitreous tap, and vitreous transplantation. Other publications were also considered as a potential source of information when referenced in relevant articles.Results: The first description of vitreous removal for treatment of eye disorders dates the 17th century; it was conducted by a Dutch surgeon Anton Nuck (1650-1692) in a case of hydrophthalmia. In English literature, the first description of vitrectomy is attributed to the American surgeon John Collins Warren (1778-1856). This method was implemented in the spontaneous dislocation of the crystalline lens. As the fibrillar structure of the vitreous once destroyed could not be regenerated, the researchers aimed to restore the chemical composition of the vitreous. For several decades, vitreous transplantation was performed for the treatment of vitreous hemorrhages and retinal detachment.Conclusion: Although the achievements of vitreoretinal surgery preceding Machemer's inventions are uncommonly reported, they have contributed to the concept and understanding of the treatment modalities.RETINA 41:1364-1372, 2021V itreoretinal surgical techniques have evolved during the last decades because of the development and evolution of pars plana vitrectomy.

These well-known improvements have increased the efficacy and safety of contemporary vitrectomy. The variety of conditions that can be successfully treated with vitreoretinal surgery has greatly expanded and includes complications of diabetic retinopathy, vitreous opacities, epiretinal membranes, macular holes, and retinal detachments.

Background and objective Current literature review fails to disclose any series describing the use of two-port vitrectomy in adult patients. This study was performed to determine the feasibility and efficacy of pars plana vitrectomy surgery using two (rather than three or four)-port access for treatment of diabetic patients with nonclearing vitreous haemorrhage due to retinal neovascularization. Design Interventional prospective case series: to measure ability to allow for longterm resolution of chronic uncomplicated vitreous haemorrhage in diabetic patients, and to study the frequency and nature of complications associated with this technique. Methods Two-port pars plana vitrectomy (with endolaser treatment and membrane delamination if necessary) was performed in a prospective series of 12 consecutive diabetic patients with nonclearing vitreous haemorrhage due to retinal neovascularization. Results Successful removal of vitreous haemorrhage resulted in all patients. No visually significant intraoperative complications occurred. Best postoperative visual acuity correlated with lenticular and macular perfusion status. Conclusion Two-port pars plana vitrectomy is an efficient (and potentially safer and faster) alternative to the standard three-port vitrectomy in selected patients.
