objective: to determine the sensivity and specifity of ocular ultrasonography in detecting vitreoretinal lesion prior to deep vitrectomy in patients with opaque media. method: the hospital records of patients undergoing deep vitrectomy in a defined period at shiraz khalili hospital were reviewed. sonographic reports given by a sonologist and operation reports given by a vitreoretinal fellowship...

Retinal detachment (RD), its rupture, concussion, hemorrhage require urgent ophthalmic surgical intervention without fail. Restoring the anatomical integrity of detached retina, speed intervention, choice access and method surgery, quality instrument are directly causally related to visual acuity, number severity postoperative complications. The best complex ophthalmosurgical solutions relieve ...

Proliferative vitreoretinopathy (PVR) is the principal cause of failure in retinal detachment (RD) surgery and is characterized by the proliferation of different cell types leading to the formation of cellular membranes on both sides of the retina. These membranes have the capability of contracture resulting in retinal redetachment. Despite marked improvement in vitreoretinal surgical technique...

purpose : to investigate the risk factors and causes for blindness in behcet’s disease (bd). methods : in this preliminary retrospective case series we have investigated 27 bd patients (54 eyes), legally blind (vision 0.1 or less) at least in one eye at the last visit (2006), and compared them with 54 eyes of 27 non-blind patients (control group), matched individually and consequently in terms ...

Purpose. To evaluate the efficacy of silicone oil (S.O) reinjection without macular buckling for treatment of recurrent myopic macular hole retinal detachment (MHRD) after silicone oil removal. Methods. A retrospective consecutive interventional study from medical reports on cases of myopic MHRD. Fifty-three eyes of 51 patients underwent silicone oil removal after successful repair of MHRD were...

BACKGROUND AND OBJECTIVE Acute retinal necrosis (ARN) may lead to severe visual loss because of its rapid progression and high likelihood of retinal detachment (RD). This study investigates whether combination systemic and intravitreal antiviral therapy is superior to systemic antiviral therapy alone. PATIENTS AND METHODS Single-center, interventional, comparative case series of patients with...

Purpose. To quantify the frequency of visual loss after successful retinal detachment (RD) surgery in macula-on patients in a multicentric, prospective series of RD. Methods. Clinical variables from consecutive macula-on RD patients were collected in a prospective multicentric study. Visual loss was defined as at least a reduction in one line in best corrected visual acuity (VA) with Snellen ch...

BACKGROUND Despite the progress in vitreoretinal surgery and the importance of silicone oil as an adjunct for the treatment of complex forms of retinal detachment, controversy still surrounds the issue of selecting the proper oil viscosity for clinical use. Herein, we evaluate the outcomes of retinal detachment (RD) surgery after removing silicone oils of different viscosities. METHODS In thi...
