PURPOSE: To report rates and timing of retreatments, new break formation, and vitreoretinal surgical intervention after initial treatment of retinal breaks, and to identify factors associated with increased rates of additional vitreoretinal interventions. METHODS: Retrospective, consecutive case series of all patients who were diagnosed with a retinal break and underwent laser retinopexy for prophylaxis of retinal detachment at the Bascom Palmer Eye Institute, Miami, FL, from 2013 through 2016 were reviewed...

Purpose: To report the outcomes of pneumatic retinopexy (PR) performed as a primary surgical procedure for rhegmatogenous retinal detachment (RRD) or as a secondary procedure for recurrent RRD. Methods: We retrospectively analyzed case records of 54 patients (54 eyes) who underwent PR for RRD by injecting 0.3 ml of perfluoropropane (C3F8) in the vitreous cavity and cryopexy to break in the same sitting, followed by positioning. Results: A total 54 eyes of 54 patients aged between 17 and 84 years (mean - 51...

Retinal detachment with subsequent silicone oil retinopexy is not uncommon. A known complication of silicone retinopexy is intraventricular migration of the intraocular silicone oil. While the oil itself does not result in direct pathology, misdiagnosis may lead to an unnecessary diagnostic workup and possibly predispose the patient to surgery intervention. Silicone oil typically appears hyperdense on computer tomography (CT) and hyperintense on T1-weighted magnetic resonance (MR). These imaging findings may mimic a mass or blood products...

Diabetic retinopathy (DR), the most common complication of diabetes mellitus, is the leading cause of new cases of blindness in middle-aged and elderly in the Asia-Pacific. It has been estimated that 51% of all those with blindness due to DR globally (n = 424,400) and 56% of those with visual impairment due to DR (2.1 million) come from the Asia-Pacific. Prevalence of DR among those with diabetes ranged from 10% in India to 43% in Indonesia within the Asia-Pacific. Awareness of DR among persons with diabetes ranged from 28% to 84%...

PURPOSE: The purpose of the study was to report the outcomes of pneumatic retinopexy (PR) for rhegmatogenous retinal detachment (RRD). METHODS: A retrospective chart review of all patients with RRD who were managed with PR at the King Khaled Eye Specialist Hospital between 2000 and 2014. Data were collected on preoperative ocular history, characteristics of the RRD, postoperative anatomical and visual outcomes, and secondary surgeries. RESULTS: Sixty-five eyes comprised the study sample with mean a follow-up of 42 months...

PURPOSE: To determine the concentrations of different gas tamponades in air to achieve 100% fill of the vitreous cavity postoperatively and to examine the influence of eye volume on these concentrations. METHODS: A mathematical model of the mass transfer dynamics of tamponade and blood gases (O2, N2, and CO2) when injected into the eye was used. Mass transfer surface areas were calculated from published anatomical data. The model has been calibrated from published volumetric decay and composition results for three gases sulphahexafluoride (SF6), hexafluoroethane (C2F6), or perfluoropropane (C3F8)...

PURPOSE: To evaluate the anatomical and visual outcomes of patients who underwent pneumatic retinopexy by vitreoretinal fellows. METHODS: We included 198 eyes (198 patients) that underwent pneumatic retinopexy by vitreoretinal fellows at a single academic institution between November 2002 and June 2016. Main outcomes were single-operation success and final anatomical success in retinal reattachment, as well as visual acuity at 3 months and 6 months after treatment...

BACKGROUND AND OBJECTIVE: To compare pneumatic retinopexy (PR) and scleral buckle for the repair of primary rhegmatogenous retinal detachment. PATIENTS AND METHODS: Retrospective analysis of 90 patients undergoing surgery for primary rhegmatogenous retinal detachment, with 46 patients undergoing PR compared with 44 patients undergoing scleral buckle procedure (SBP). RESULTS: Both groups had similar baseline characteristics. Single surgery reattachment rate was 95...

BACKGROUND: Severe vision-impairing ocular inflammation is rarely reported following extensive laser. Previous cases have involved retinal photocoagulation for diabetic retinopathy resolving over days. This report documents a rare instance of this where encircling retinopexy/cerclage was done as fellow eye retinal detachment prophylaxis in a patient with no overt comorbidities. RESULTS: A panuveitis-like reaction with severe, near-total visual impairment was documented 1 day following single-sitting encircling laser retinopexy/cerclage done as fellow eye prophylaxis for a 21-year-old male presenting with total retinal detachment in the other eye...

BACKGROUND/PURPOSE: We report the first two cases of postoperative opacification of scleral-sutured Akreos AO60 intraocular lens after vitrectomy with the gas tamponade. METHODS: Two patients with ectopia lentis underwent pars plana vitrectomy, pars plana lensectomy, and scleral fixation of an Akreos AO60 intraocular lens with Gore-Tex suture. Retinal breaks were noted during vitrectomy and consequently intravitreal gas tamponade was used after endolaser retinopexy...

Objective To evaluate the efficacy of maximal pneumatic retinopexy (PR) and subretinal fluid (SRF) drainage combined with scleral buckling (SB) in the treatment of complicated rhegmatogenous retinal detachment (RRD). Methods Patients with RRD who underwent maximal PR and SRF drainage combined with SB from June 2007 to June 2012 were included in this multicenter retrospective study. The outcome measures were the primary and final operation success rates and best-corrected visual acuity (BCVA). Results In total, 159 consecutive patients were included...

PURPOSE: To assess the accuracy of B-scan ultrasound (U/S) in diagnosing cases of acute fundus obscuring vitreous hemorrhage (FOVH) using a standardized scan protocol and dedicated ophthalmic ultrasonographer. METHODS: Consecutive patients presenting with acute FOVH of unknown cause, between January 2013 and December 2014, were prospectively recruited. Patients underwent a scan performed by a dedicated ultrasonographer, utilizing a systematic scan sequence and using an ocular specific U/S device...

PURPOSE: Knowledge on the utility of prophylactic 360° laser retinopexy before pars plana vitrectomy in the absence of peripheral retinal pathology is limited. This study compares the occurrence of rhegmatogenous events in the setting of small-gauge pars plana vitrectomy with and without prophylactic preoperative laser. METHODS: Our multicenter, retrospective case-control analysis reviewed patients who underwent epiretinal membrane removal or macular hole repair through 23- or 25-gauge pars plana vitrectomy: 205 controls who did not receive prophylactic laser and 176 cases who received preoperative prophylactic laser retinopexy anterior to the equator...

PURPOSE: To date, only silicone oils and gases have the appropriate characteristics for use in vitreo-retinal surgery as vitreous substitutes with intraocular tamponading properties. This preliminary study evaluated the safety and efficacy of medium-chain triglycerides (MCTs) for use as a tamponading agent in minipigs. METHODS: In 15 minipigs, 15 right eyes underwent vitrectomies followed by injection of MCT tamponade (day 1). Two groups were defined. In Group A (ten eyes), the surgical procedure before MCT injection included induced rhegmatogenous retinal detachment (RRD), retina flattening, and retinopexy...

PURPOSE: The aim of this paper was to report 2 patients (3 eyes) with proliferative diabetic retinopathy (PDR) who showed marked sheathing of the retinal arterioles that was ultimately attributed to calcification following vitrectomy. CASES: Case 1 involved a 65-year-old female with PDR who underwent bilateral vitrectomy for traction retinal detachment. Postoperatively, bilateral retinal redetachment (reRD) was observed. Sheathing of the retinal arterioles was observed at the same time, yet was not apparent preoperatively...

Giant retinal tears (GRTs) are full-thickness circumferential tears of more than 90 degrees of the retina that are associated with vitreous detachment. They are related to ocular trauma, high myopia, aphakia, pseudophakia, genetic mutations involving collagen and young age. GRTs comprise 1.5% of all rhegmatogenous retinal detachments and the average age of incidence is 42 years. GRTs are more common in males, as 72% of all cases occur in males. The incidence of GRTs in the general population is estimated to be 0...
