Retinectomy

PURPOSE: To analyze the visual and anatomical outcomes for eyes with rhegmatogenous retinal detachment (RRD) and advanced proliferative vitreoretinopathy (PVR) undergoing giant peripheral retinotomy (GPR) using 25-gauge pars plana vitrectomy (PPV). METHODS: In this retrospective multi-center study, patients with RRD with either anteroposterior or circumferential retinal shortening and advanced PVR requiring more than 90-degree GPR with/without relaxing retinotomy were included...

BACKGROUND: Stickler syndrome is a hereditary connective tissue disorder associated with ocular, orofacial, musculoskeletal, and auditory impairments. Its main clinical characteristics include retinal detachment, hearing loss, and midface underdevelopment. In clinical practice, macrocyst is rarely reported in retinal detachment cases with Stickler syndrome. CASE PRESENTATION: We report the case of a 7-year-old child who developed a rhegmatogenous retinal detachment (RRD) in the right eye, accompanied by multiple peripheral macrocysts...

We investigated the impact of drainage retinotomy on the outcome of pars plana vitrectomy for repair of rhegmatogenous retinal detachment (RRD). This study was a retrospective observational multicenter study. All patients were registered with the Japan-Retinal Detachment Registry. We analyzed 1887 eyes with RRD that had undergone vitrectomy and were observed for 6 months between February 2016 and March 2017. We compared the baseline characteristics and postoperative outcomes between eyes with and without drainage retinectomy...

PURPOSE: To report a rare case of progressive retinoschisis and retinal detachment after uncomplicated macular hole (MH) surgery. CASE DESCRIPTION: A 67-year-old man with recent onset vision complaints in the right eye (visual acuity - 20/30), was diagnosed with a small idiopathic full-thickness MH. He underwent a 3-port 25G pars plana vitrectomy surgery with internal limiting membrane peeling and air endotamponade. RESULTS: MH closed with a normal foveal contour and intact retinal layers by the 1st post operative week and vision improved to 20/20...

CLINICAL RELEVANCE: Primary retinectomy in eyes not previously vitrectomized has been previously rarely performed in a minority of cases, unlike non-primary retinectomies in vitrectomized eyes. BACKGROUND: This paper aims to determine anatomical and functional outcomes of primary retinectomy, and to assess structural macular changes among successful cases. METHODS: In this retrospective multicentre cohort-study, 35 primary retinectomies in eyes undergoing initial vitrectomy for rhegmatogenous retinal detachment complicated by proliferative vitreoretinopathy C or D between 2014 and 2021 were included...

PURPOSE: To highlight a potential alternative to additional surgery for management of retinal re-detachment through the use of additional facedown positioning with silicone oil tamponade. METHODS: Retrospective case-series of two patients evaluated with examination, multimodal imaging, including fundus photography, optical coherence tomography (OCT), and fluorescein angiography. RESULTS: In case 1, a 70-year-old female patient underwent surgery for a full-thickness macular hole with associated macula-off retinal detachment, but experienced a recurrent detachment and underwent a second surgery with silicone oil placement...

Retinotomy refers to "cutting" or "incising" the retina, whereas retinectomy denotes "excising" the retina. Retinotomies and retinectomies aid in tackling traction and retinal shortening that persist following membrane dissection and scleral buckling. We performed a literature search using Google Scholar and PubMed, followed by a review of the references procured. All relevant literature was studied in detail and summarized. We discuss the indications of retinotomies and retinectomies for relaxing retinal stiffness, accessing the subretinal space for choroidal neovascular membrane, hemorrhage and abscess clearance, drainage retinotomies to allow retinal flattening, radial retinotomies to release circumferential traction, harvesting free retinal grafts, and prophylactic chorioretinectomies in trauma...

PURPOSE: To report a case of a recurrent macular hole (MH) and atrophic age-related macular degeneration in a patient, treated with human amniotic membrane transplant. METHODS: Interventional case report. RESULTS: A 72-year-old man was referred to our Retina Unit for a recurrent MH associated with atrophic age-related macular degeneration. The patient was already operated for a full-thickness MH without any anatomical and functional benefit...

This study assessed prognostic factors and the role of vitrectomy in patients with subretinal abscesses secondary to K. pneumoniae endophthalmitis. We reviewed published studies, including three cases from our cohort. Among 50 eyes, 26 had poor visual outcomes (final visual acuity <20/800, eyeball removal, or phthisis bulbi). Poor outcomes correlated with delayed ocular symptom-to-diagnosis time, initial visual acuity <20/800, severe vitritis, and macular involvement of abscesses ( p  < 0...

PURPOSE: To report a rare case of a subretinal Phialophora richardsiae abscess in a patient with chronic granulomatous disease (CGD). METHODS: A 21-year-old male with CGD and a history of invasive pulmonary aspergillosis presented with progressive loss of vision and pain in his left eye. He was found to have a subretinal abscess with a macula involving serous retinal detachment. A diagnostic and therapeutic pars plana vitrectomy, subretinal biopsy with debridment, inferior retinectomy and silicone oil tamponade was performed...

PURPOSE: To evaluate the outcomes and complications after different surgical management of cases with significant sumacular hemorrhage (SMH) of size more than 4 disc diameter (DD). METHODS: It was a retrospective interventional study. All consecutive 103 cases of significant SMHs were treated by vitrectomy and divided into three groups. In Group A (<4 weeks, confined to the macula or extending inferiorly, n = 62), vitrectomy, subretinal cocktail of tissue plasminogen activator (tPA), antivascular endothelial growth factor, and air with SF6 gas; in Group B (4-8 weeks, extending beyond macula, n = 31), subretinal tPA followed by SMH drainage either by retinotomy (Group B-1, n = 17) or by temporal 180-degree retinectomy (Group B-2, n = 14) with silicone oil (SO) tamponade; and in Group C (>8 weeks, extending beyond macula, n = 10), SMH removal with autologous retinal pigment epithelium (RPE)-Choroid patch graft transplantations with SO tamponade were performed...

PURPOSE: To measure the proportion of unexplained and all causes of visual loss following primary rhegmatogenous-retinal-detachment (RRD) repair, comparing gas tamponade (SF6 , C2 F6 , C3 F8 ), silicone oil (SO, 1000cs and 5000cs) and heavy silicone oil (Densiron). METHODS: Retrospective, continuous, comparative study from 01/1/2017-31/5/2021. All primary RRDs were included after successful removal of SO and Densiron. Primary failures were excluded. Visual loss was defined as reduction of ≥0...

PURPOSE: To report the anatomical and functional outcomes of medium-term perfluoro-n-octane (PFO) tamponade as a rescue procedure in very complex retinal detachments (RD). METHODS: We reviewed the case records of 35 consecutive patients who underwent vitrectomy for very complex RD due to diverse etiologies. The surgical complexity was so graded due to the intraoperative failure to ascertain complete retinal re-attachment; PFO was used as rescue tamponade for 2-4 weeks...

Human amniotic membranes (hAMs) are extraembryonic tissues currently employed in the treatment of many ocular and systemic diseases. Several reports indicate that hAMs can suppress the signaling pathway of tissue growth factor beta (TGF-β), a cytokine that plays a major role in the pathogenesis of proliferative vitreoretinopathy (PVR) through the induction of epithelial-mesenchymal transition (EMT) in exposed retinal pigmented epithelium (RPE) cells. The present study was conducted to evaluate the efficacy of a modified vitrectomy procedure (hAMP-V) involving the extensive coverage of exposed RPE with hAM patches to prevent postoperative PVR in a series of 15 cases of retinal detachment complicated by severe preoperatory PVR...

PURPOSE: To perform a pilot study to evaluate the role of sub-silicone oil Triamcinolone Acetonide (TA) crystal drops in complex Retinal Detachment (RD) with extreme proliferative vitreoretinopathy (PVR) requiring 360-degree relaxing retinectomy (RR). DESIGN: It was a retrospective pilot study. MATERIALS AND METHODS: It was a retrospective case-control pilot study. TA-assisted 23G or 25G vitrectomy was done in 24 complex RDs with extreme PVR where 360 degree RR had to be performed...

BACKGROUND: Recurrent retinal detachment (Re-RD) usually affects the prognosis of surgery for rhegmatogenous retinal detachment (RRD). Previous clinical studies of Re-RD were not specific. This study aimed to analyze the clinical characteristics of Re-RD in post-vitrectomy eyes with RRD and surgical outcomes after revitrectomy without combining it with retinectomy or scleral buckling. METHODS: This is a retrospective case series analyzed the ocular characteristics of 20 recurrent and contralateral eyes, evaluated the significance of the associations between variables before reoperation and the final best-corrected visual acuity (BCVA), and calculated the outcome of revitrectomy...

BACKGROUND: To describe the anatomical and functional outcomes and late complications in patients who developed inferior proliferative vitreoretinopathy (PVR) in silicone oil-filled eyes and who required reoperation with large inferior retinectomy. METHODS: This is a single-center, retrospective, interventional case series analysis. The study involved 18 individuals with tractional retinal re-detachment due to PVR development inferiorly in eyes who had undergone prior pars plana vitrectomy and silicone oil as a tamponade...

PURPOSE: To present the clinical characteristics, surgical outcomes, and surgical complications of patients with congenital X-linked retinoschisis who underwent vitrectomy for bullous schisis cavity hanging over or threatening the macula. METHODS: Nine patients with congenital X-linked retinoschisis (12 eyes) who underwent vitrectomy at three tertiary hospitals and completed ≥3 years of postoperative follow-up were retrospectively investigated. Data were collected from patients' charts, including age at vitrectomy, surgical procedures, and postoperative complications...
