The aim of this prospective study was to determine the possible influence of the silicone oil tamponade after vitrectomy on the early intraocular pressure (IOP) elevation, which is a major risk factor for developing secondary glaucoma in patients with vitreal and retinal proliferative changes. The research included 110 patients which were allocated in three groups according to the medical histo...

PURPOSE To evaluate the efficacy of the inverted internal limiting membrane (ILM) flap technique in vitrectomy for macular hole (MH) with retinal detachment (RD) compared with vitrectomy using ILM peeling. METHODS A retrospective case series study was performed. Twenty-two eyes of 22 patients who underwent vitrectomy for MH with RD and followed-up more than 12 months after the surgery were in...

BACKGROUND AND OBJECTIVE To describe a technique of 25-gauge pars plana lensectomy with primary posterior capsulotomy and sparing of the anterior lens capsule that is suitable for all lens densities. PATIENTS AND METHODS The authors describe a technique they routinely employ for pars plana vitrectomy using primarily a 25-gauge, three-port approach with intraoperative lens density assessment a...

This is a case of Valsalva retinopathy during the season annual transboundary haze pollution in Sarawak. A 22-year-old man with no known medical illness developed sudden onset painless visual acuity loss preceded by persistent cough. Left eye fundus showed dense preretinal haemorrhage covering optic disc extendinginferiorly breakthrough vitreous haemorrhage. The patient underwent pars plana vit...

Background and Objective To evaluate full-thickness macular hole (MH) formation in the postoperative period after initial vitrectomy for rhegmatogenous retinal detachment (rRD). Materials and Methods We retrospectively reviewed the medical records of 4 consecutive eyes that required additional vitrectomy for full-thickness MH between April 2013 and March 2016 after undergoing an initial vitre...

Since Kelly and Wendel [Arch Ophthalmol 1991;109:654-659] first reported successfully treating macular holes (MHs) using pars plana vitrectomy in 1991, MH surgery has been constantly improved. For example, introducing the removal of the internal limiting membrane considerably increased the closure rate of MHs, and the advent of microincision vitrectomy surgery reduced surgical trauma and decrea...

Vitreous hemorrhage is the most frequent finding in ocular trauma. In cases with obscured fundus visualization associated pathologies (retinal tear, choroidal detachment, intraocular foreign body, retinal etc.) should be evaluated by ultrasonography and vitreous motility monitored even if retina attached. A decrease points to development of proliferative vitreoretinopathy requires early vitrect...

We evaluated the effectiveness of performing a core vitrectomy to prevent intraoperative posterior chamber pressure evaluation in eyes at high risk for development of this complication, prior to penetrating keratoplasty, extracapsular cataract extraction and posterior chamber lens (IOL) implantation. Results in 10 cases with core vitrectomy were compared with 10 cases without (controls); in all...

BACKGROUND The role of pars plana vitrectomy (PPV) for endophthalmitis has evolved over recent decades but the literature is lacking on comparisons between small-gauge and 20-gauge vitrectomy. OBJECTIVE To evaluate evolving etiological and microbiological trends in patients undergoing vitrectomy for endophthalmitis and to compare culture-positive rates and visual outcomes between small-gauge ...
