#1
Zhong Lin, Nived Moonasar, Rong Han Wu, Robin R Seemongal-Dass
PURPOSE: Traditionally acceptable methods of anesthesia for vitrectomy surgery are quite varied. However, each of these methods has its own potential for complications that can range from minor to severe. The surgery procedure of vitrectomy for symptomatic vitreous floaters is much simpler, mainly reflecting in the nonuse of sclera indentation, photocoagulation, and the apparently short surgery duration. The use of 27-gauge cannulae makes the puncture of the sclera minimally invasive...

BACKGROUND: Endophthalmitis is a severe inflammation of the anterior or posterior (or both) chambers of the eye that may be sterile or associated with infection. It is a potentially vision-threatening complication of cataract surgery. Prophylactic measures for endophthalmitis are targeted against various sources of infection. OBJECTIVES: To evaluate the effects of perioperative antibiotic prophylaxis for endophthalmitis following cataract surgery compared with no prophylaxis or other form of prophylaxis...

PURPOSE: To demonstrate the effectiveness of the endoscopic transcaruncular and transconjunctival approach in the repair of combined medial and inferior orbital wall fractures. METHODS: A retrospective chart review was conducted on 160 patients with combined medial and inferior orbital wall fractures. All patients underwent surgery via an endoscopic transcaruncular and transconjunctival approach without lateral canthotomy, performed by a single surgeon. Porous polyethylene sheets (1...

M P Schittkowski
A case is presented of a 54-year old patient who had been treated 10 months previously with enucleation for a painful blind eye. This led to severe and chronic pain in the orbital region that did not respond to conventional pain management. However, a single 1.5 ml injection of 96 % ethanol led to almost complete resolution of pain for the follow-up period of 6 months. Orbital pain after enucleation or evisceration may originate from the implant itself, the prosthesis, the socket or the sinuses. Taking a careful medical history and an examination, including orbital scans, are necessary to decide on the correct differential diagnosis...

We analyzed the effects of anti-vascular endothelial growth factor (VEGF) drugs combined with photodynamic therapy (PDT) in the treatment of age-related macular degeneration (AMD). Ninety-six cases (192 eyes) of AMD were included in this study and randomly divided into the observation group and control group (n=48 cases per group). The control group was administered the treatment of Lucentis intravitreal injection alone and the observation group was administered Lucentis combined with PDT. The therapeutic effects were compared...

INTRODUCTION: Spectral shaping aims to narrow the X-ray spectrum of clinical CT. The aim of this study was to determine the image quality and the extent of radiation dose reduction that can be achieved by tin prefiltration for parasinus CT. METHODS: All scans were performed with a third generation dual-source CT scanner. A study protocol was designed using 100 kV tube voltage with tin prefiltration (200 mAs) that provides image noise levels comparable to a low-dose reference protocol using 100 kV without spectral shaping (25 mAs)...

BACKGROUND/AIM: To investigate the effect of deep sclerectomy on retrobulbar blood flow. MATERIALS AND METHODS: This prospective study included 20 eyes of 20 patients with open angle glaucoma. Color Doppler imaging (CDI) examinations were performed before and 2, 12, and 24 weeks after deep sclerectomy. Peak systolic velocity (PSV), end diastolic velocity (EDV), and resistance index (RI) were measured for the ophthalmic artery (OA), central retinal artery (CRA), and temporal and nasal short posterior ciliary arteries (SPCAs) at each examination and the results were compared...

A 25-year-old man with Type 1 diabetes mellitus experienced rapid visual decline and was scheduled for right cataract surgery. At the time of administering an inferotemporal retrobulbar block, a white discharge appeared spontaneously on the surface of the globe. Superotemporally a cyst was found and its contents were subtotally evacuated. Microscopically, eosinophilic, acellular material with chatter artifact and small vacuoles was detected and initially thought to represent a lens choristoma. This material stained moderately with the periodic acid Schiff method and was focally Congo red positive without apple green birefringence; it also stained blue with the Masson trichrome method...

BACKGROUND AND AIMS: To evaluate the efficacy of orbital radiotherapy (OR) for the treatment of thyroid eye disease (TED). METHODS: Thirty-five consecutive patients with active TED with contraindications to steroid therapy received a course of OR. Bilateral retrobulbar irradiation was performed with a total dose of 20 Gy. 7-points clinical activity score (7-CAS), ocular motility, visual acuity (VA), exophthalmos and eyelid retraction were prospectively evaluated at 3, 6 and 12 months and compared with baseline data...

OBJECTIVE: To compare the localization and distribution of two different anesthetic fluid volumes around equine cadaver eyes to determine an appropriate volume for a single sub-Tenon's injection in horses. PROCEDURE: A single sub-Tenon's injection of 2% lidocaine was performed in 10 equine cadaver heads (20 eyes) using two different volumes (7 mL on one side and 10 mL on the opposite side). The posterior circular distribution of the anesthetic was quantified in sagittal, dorsal, and transverse MRI (T2W-TSE) sequences and evaluated independently by three board-certified radiologists...

PURPOSE: To describe several essential surgical techniques that overcome difficulties in performing Descemet membrane endothelial keratoplasty (DMEK) for inexperienced surgeons, especially those who perform DMEK on eyes of Asian patients. METHODS: Nine eyes of 9 Asian patients with bullous keratopathy who underwent DMEK were analyzed retrospectively. All patients were given a diuretic such as D-mannitol or acetazolamide shortly before surgery, with retrobulbar anesthesia and a Nadbath facial nerve block...

Jie Huang, Ni Zhongge, Philip Finch
OBJECTIVES: Varicella-zoster virus reactivation can cause permanent histological changes in the central and peripheral nervous system. Neural inflammatory changes or damage to the dorsal root ganglia sensory nerve fibers during reactivation can lead to postherpetic neuralgia (PHN). For PHN of the first division of the fifth cranial nerve (ophthalmic division of the trigeminal ganglion), there is evidence of inflammatory change in the ganglion and adjacent ocular neural structures. First division trigeminal nerve PHN can prove to be difficult and sometimes even impossible to manage despite the use of a wide range of conservative measures, including anticonvulsant and antidepressant medication...

PURPOSE: To evaluate ocular hemodynamic changes using color Doppler ultrasonography imaging (CDI) with an emphasis on unaffected eyes of patients with central serous chorioretinopathy (CSC). METHODS: Twenty-seven patients with active CSC and 25 controls were analyzed using spectral domain-optical coherence tomography (SD-OCT) and CDI for choroidal imaging and evaluation of retrobulbar vessels, respectively. RESULTS: Resistive index (RI), pulsatility index (PI), and peak systolic velocity (PSV) of the ophthalmic artery (OA) and PSV, end-diastolic velocity (EDV), and mean velocity (Vmean) of the central retinal artery (CRA) in the patient group were less than those in the control group...

OBJECTIVE: To evaluate the results of applying retrobulbar chlorpromazine in the management of patients with painful blind eyes or with very poor vision. METHODS: A retrospective, descriptive review was carried out on the medical records of 33 patients who were treated with a retrobulbar injection of chlorpromazine (25mg) for the management of painful blind eyes in Centro Oftalmológico Virgilio Galvis. RESULTS: Pain control was achieved in 90% of cases (with mean follow-up of 2...

PURPOSE: Obtaining adequate tissue from retrobulbar masses remains a challenge. To this end, a new method of retrobulbar mass biopsy using MRI guidance is presented. MATERIALS AND METHODS: Two patients (7- and 71-year-old male) with indeterminate retrobulbar masses underwent bioptic and cytological samplings using MR-compatible 18G and 20-22G needles, and multi-planar MR fluoroscopy. An inferior approach was taken to avoid injury to the optic nerve and ophthalmic arteries...
