Perioperative retina evaluation of the cataract surgery patient.

PURPOSE OF REVIEW: To describe recent evidence regarding cataract surgery in patients with coexisting retinal disease, focusing on factors that are important to the perioperative evaluation and treatment of this patient population. RECENT FINDINGS: Studies in patients with age-related macular degeneration have yielded good visual gains without progression of neovascular disease or increased need for intravitreal antivascular endothelial growth factor therapy. Uveitic patients similarly gain vision on average, and control of inflammation remains paramount. Perioperative treatment with intravitreal antivascular endothelial growth factor and corticosteroid help mitigate postoperative macular edema in patients with diabetic macular edema. Risk of retinal detachment is elevated postcataract surgery, but evidence regarding prophylactic treatment of peripheral retinal pathology is lacking. Intracameral antibiotics have reduced rates of postcataract surgery endophthalmitis in recent population-based retrospective studies. SUMMARY: Favorable visual acuity outcomes are possible following cataract surgery in patients with retinal disease, including uveitis, diabetic macular edema, and age-related macular degeneration. Perioperative control of retinal disease activity is desired, but level 1 evidence to guide best practices regarding optimal timing and nature of perioperative treatment remains limited. Prevention of postoperative retinal detachment and endophthalmitis is deserving of additional study.

An Unlikely Cause of Abdominal Pain.

Cecal bascule is a rare subtype of cecal volvulus where the cecum folds anterior to the ascending colon causing intestinal obstruction. It is a challenging diagnosis to make in the emergency department, as the mobile nature of the cecum leads to a great deal of variation in its clinical presentation. Our discussion of a 78-year-old female who presented with abdominal pain and was found to have a cecal bascule requiring right hemicolectomy, demonstrates how emergency physicians must expand their differential diagnosis for patients reporting signs of intestinal obstruction. Though cecal bascule does not present often, the need for early surgical intervention necessitates a high level of clinical suspicion to prevent life-threatening complications.

Prevalence of vitreomacular adhesion: an optical coherence tomography analysis in the retina clinic setting.

PURPOSE: The aims of this study were to determine the prevalence of vitreomacular adhesion (VMA) in a random sample of clinical patients at three US retina clinics and to assess comorbid retinal conditions, ocular diseases, prior treatment history, and other medical histories. PATIENTS AND METHODS: This observational, retrospective cohort study was based on patients from the Doheny Eye Centers, Duke Eye Center, and Tufts Medical Center who received a bilateral spectral domain optical coherence tomography (SD-OCT) scan (one scan/eye) for clinical evaluation with available medical records. The study had three phases: 1) collection of retrospective patient data; 2) review of OCT scans at a reading center to assess VMA and associated conditions; and 3) analyses and reporting of data on the prevalence of VMA, patient demographics, and comorbid conditions. Data were obtained from electronic health records and OCT grading forms. Outcome measures from bilateral SD-OCT scans and medical records included OCT evaluation of VMA and retinal comorbid conditions. RESULTS: In 719 patients with 1,483 reviewable OCT scans, the prevalence of VMA was estimated at 14.74% (90% CI, 12.58%-16.92%). The prevalence of unilateral VMA was estimated at 12.39%, while bilateral VMA was 2.36%. In patients with VMA, 34 out of 123 eyes with VMA (27.64%) also had fovea deformed by vitreomacular traction. Macular hole (MH) was significantly more prevalent in VMA-diagnosed eyes versus non-VMA-diagnosed eyes (6.5% versus 1.9%; P=0.02). There was a significantly higher incidence of full-thickness MH (P=0.008), operculum/flaps (P<0.0001), and lamellar or pseudo-holes (P=0.048) in VMA-diagnosed versus non-VMA-diagnosed eyes. Age, MH as a comorbid condition, full-thickness MH, lamellar or pseudo-holes, and operculum were predictive of a VMA diagnosis. CONCLUSION: The prevalence of VMA was estimated at 14.74% in a random sample of patients from three retina clinics. VMA diagnosis can be predicted by factors, including age, MH as a comorbid condition, and lamellar or pseudo-holes.
