We report a case of a patient with a highly hyperopic eye who underwent cataract surgery combined with vitreous surgery to create a posterior vitreous detachment (PVD) to prevent choroidal neovascularization (CNV). A 78-year-old man noticed a decrease in his vision due to a cataract in his right eye. The patient had a severe visual loss in his left eye because of a CNV 2 years after a cataract ...
We present multi‐modal imaging of two phakic patients who developed lens nucleus dislocation following multiple complicated vitrectomy surgeries. We feel vitreoretinal physicians should be aware of this phenomenon and its presentation. To the best of our knowledge, high‐quality multi‐modal imaging of this presentation has not been published. Two phakic patients with moderate nuclear sclerosis u...
Case Reports Case 1, a male, aged 52, had had a right macular haemorrhage about 20 years previously, and for a period of 4 months had noticed deterioration of the visual acuity of the left eye. The right eye showed a posterior staphyloma and advanced macular degeneration typical of myopia; the left eye had a central retinal detachment occupying the area of a posterior staphyloma (Fig. 1). The v...
BACKGROUND Vitreomacular adhesion can lead to pathologic traction and macular hole. The standard treatment for severe, symptomatic vitreomacular adhesion is vitrectomy. Ocriplasmin is a recombinant protease with activity against fibronectin and laminin, components of the vitreoretinal interface. METHODS We conducted two multicenter, randomized, double-blind, phase 3 clinical trials to compare...
INTRODUCTION To evaluate the vitreoretinal complications in myopes after Visian implantable collamer lenses (ICL) implantation. MATERIALS AND METHODS This is a retrospective, observational, non-comparative clinical study that evaluated 617 consecutive myopes who underwent ICL implantation at the Department of Refractive Surgery, Yemen Magrabi Hospital, Sana'a, Yemen between July 2006 and May ...
PURPOSE To clarify vitrectomy indications in the treatment of vitreous floaters. METHODS This is a retrospective study of four patients, four eyes (age, 42-65 years), who underwent vitrectomy for the treatment of vitreous floaters. Two patients had a total posterior vitreous detachment. All patients were required to think about the intervention for several months before consenting. RESULTS ...
INTRODUCTION We introduce the use of low-molecular-weight silicone oil as an infusion and as a peroperative tool to facilitate three specific surgical steps, namely internal search for retinal breaks, vitreous base shaving and drainage of subretinal fluid. METHOD AND PATIENTS Ethics committee approval was obtained to test this novel agent in a small number of cases as a pilot study. Following...
BACKGROUND Vitrectomy for symptomatic vitreous floaters carries significant risks. Justification of surgery is difficult, particularly in healthy eyes with normal visual acuity and without a posterior vitreous detachment. This is the first reported case of optical coherence tomography being utilized to objectively assess the impact of a vitreous opacity on the macula. CASE PRESENTATION A 37-y...
The recent approval by the US Food and Drug Administration of ocriplasmin for the treatment of symptomatic vitreomacular adhesion (VMA), often associated with vitreomacular traction (VMT) and macular hole (MH), has brought new attention to the field of pharmacologic vitreolysis. The need for an enzyme to split the vitreomacular interface, which is formed by a strong adhesive interaction between...
Purpose Spectral Domain Optical Coherence Tomography (SD-OCT) was used to evaluate retinal and vitreo-retinal changes that occur in highly myopic patients. Methods This prospective study included 472 eyes of 472 patients suffering from high myopia (> -6.00 D), between May 2012 and December 2015. All patients were examined, using Cirrus HD OCT (Zeiss Cirrus TM HD-OCT model 4000), to detect any...
