Prospective Comparison of VisuALL Virtual Reality Perimetry and Humphrey Automated Perimetry in Glaucoma.

Aim And Background: Automated perimetry plays an important role in the diagnosis and monitoring of glaucoma patients. The purpose of this study is to prospectively determine parity between Humphrey visual field analyzer (HVFA) perimetry (the current gold standard) and the VisuALL virtual reality perimeter (VRP).

Materials And Methods: In this prospective fully paired diagnostic accuracy study, patients with stable, long-term HVFA visual fields (horizontal dots for ≥4 consecutive visits on progression analysis) with preperimetric, mild, moderate, or severe visual field loss were familiarized with the VRP and then tested using its proprietary software.

Rotational extraction of incarcerated iris (REII): a slit lamp technique to reduce incarcerated iris after nonpenetrating deep sclerectomy for glaucoma.

Purpose: Iris incarceration is a complication of glaucoma filtering surgery that often requires surgery. We describe a technique for reduction of incarcerated iris at the slit lamp, dubbed rotational extraction of incarcerated iris (REII). A retrospective analysis of visual function and intraocular pressure (IOP) was done in patients treated with REII after nonpenetrating deep sclerectomy.

Digital Ocular Compressions Reduce Intraocular Pressure in Eyes With Tube Shunts.

Prcis: Digital ocular compressions (DOCs) decrease intraocular pressure in eyes with tube shunts by significantly greater magnitude and duration when compared with fellow eyes without filtering surgery.

Purpose: DOCs are commonly used by glaucoma surgeons to reduce intraocular pressure (IOP) in the early postoperative period. Little is known, however, about the effects of DOC in eyes with tube shunts.

Safety, efficacy, and timing of Nd:YAG laser goniopuncture after nonpenetrating deep sclerectomy for glaucoma: A retrospective cohort study.

Background: Neodymium-doped yttrium aluminum garnet laser goniopuncture is an adjuvant procedure for nonpenetrating deep sclerectomy. We investigated optimal laser goniopuncture timing and the effect of laser iridoplasty on success rates.

Methods: This single-center retrospective cohort study compared intraocular pressure control in patients with early versus late laser goniopuncture after nonpenetrating deep sclerectomy and evaluated the effects of laser iridoplasty pretreatment.

Nonpenetrating Deep Sclerectomy for Progressive Glaucoma: Long-term (5-year) Follow-up of Intraocular Pressure Control and Visual Field Survival.

Purpose: To monitor 5-year outcomes of nonpenetrating deep sclerectomy (NPDS) with mitomycin C (MMC) in a new consecutive patient cohort.

Materials And Methods: All eyes undergoing NPDS surgery between 1/08 and 6/12 were monitored for intraocular pressure (IOP), number of antiglaucoma medications (meds), and visual field indices [mean deviation (MD) and corrected pattern standard deviation (CPSD)], relative to the preoperative baseline using the two-tailed paired Student's test.

Results: Of 106 eyes undergoing NPDS with MMC, mean IOP was 19.

Clinical significance of diminutive polyps of the rectum and sigmoid colon.

A retrospective review of 637 consecutive colonoscopies with polypectomy in 526 patients was performed to determine the association of small polyps of the rectum and sigmoid colon with more proximal colonic neoplasms. All colonic polyps were proximal to the sigmoid colon in 117 procedures. Proximal neoplasms were found in 32 percent of patients with a single polyp in the rectum or sigmoid colon.

Protein C activity, stage of disease, and vascular thrombosis in colon carcinoma.

To determine the etiology of the increased incidence of postoperative deep venous thrombosis (DVT) in patients with carcinoma of the colon, serum levels of protein C were measured preoperatively in 65 patients with colorectal adenocarcinoma. Noninvasive lower-extremity Doppler studies were performed on all patients prior to discharge to assess patency of the deep veins. Six patients (9%) were found to have DVT.

Small bowel obstruction after colon resection for benign and malignant diseases.

To determine the etiology and outcome of patients with small bowel obstruction after a colon resection for benign and malignant diseases, the medical records of 118 patients who underwent 120 laparotomies for small bowel obstruction were reviewed. Contrary to previous reports, benign adhesions were responsible for the obstruction in all patients with a history of benign colon disease, 82.6 percent of patients with a history of adenocarcinoma of the colon without known recurrence, and 30.

Reliability of colonoscopy.

In an effort to determine the reliability of colonoscopy the authors retrospectively reviewed preoperative colonoscopic findings and compared them with the postoperative pathologic specimen reports. Only lesions greater than 0.5 cm were included in the comparison.

Colonic endometriosis: its clinical spectrum.

We have reviewed two cases of colonic endometriosis. The first demonstrates the more frequently encountered symptoms of partial large-bowel obstruction. The second demonstrates the less frequently encountered cyclic rectal bleeding occurring at or near the time of menses.

Crohn's disease of the epiglottis, aryepiglottic folds, anus, and rectum.

A 23-year-old white women complained of sore throat and difficulty in breathing. Examination of her larynx revealed chronic inflammatory changes of the epiglottis and aryepiglottic folds, and a biopsy demonstrated chronic granulomatous reaction. Six months later she developed chronic diarrhea, rectal pain, and typical anorectal findings of Crohn's disease.

Electrical ileal perforation: an unusual complication of colonoscopy.

A case of electrical burn perforation of the ileum is described, occurring after colonoscopic snare polypectomy from the left colon. An adequate explanation of the cause of this complication has yet to be determined.

Arterio-enteric fistulas.

The colorectal surgeon may well see arterioenteric fistulas in patients who have rectal bleeding. The initial bleeding usually stops, allowing time for evaluation, which should be done promptly because subsequent bleeding may be fatal. Exploratory laparotomy is frequently necessary to arrive at the correct diagnosis.

Drug-induced pseudomembranous enterocolitis: a new etiologic agent.

Pseudomembranous enterocolitis is an iatrogenic illness resulting from the oral or intramuscular use of broad-spectrum antibiotics. It is characterized by diarrhea, mucosal inflammation, and pseudomembrane formation in the gastrointestinal tract. The diagnosis is established by an index of suspicion in individuals who have been on antibiotic therapy, proctosigmoidoscopic examination, stool smears, cultures, and sensitivity.
