Retina scan pregnancy9/18/2023 ![]() Ultrasound is composed of sound waves with frequencies greater than 20,000 Hz, which is by approximation the upper threshold of human hearing. The visual image formed using this technique is called an ultrasonogram, a sonogram or an echogram. The machine used is called an ultrasound machine, a sonograph or an echograph. The practice of examining pregnant women using ultrasound is called obstetric ultrasonography, and was an early development of clinical ultrasonography. The usage of ultrasound to produce visual images for medicine is called medical ultrasonography or simply sonography, or echography. distances and velocities) or to generate an informative audible sound. In diagnosis, it is used to create an image of internal body structures such as tendons, muscles, joints, blood vessels, and internal organs, to measure some characteristics (e.g. 2020 18:100708.Medical ultrasound includes diagnostic techniques (mainly imaging techniques) using ultrasound, as well as therapeutic applications of ultrasound. Management of a rhegmatogenous retinal detachment in a pregnant patient. Brooks CC, Brodie F, Brodie R, Buck M, Postel EA. Outcomes of surgery for progressive symptomatic retinal detachment complicating retinoschisis. ![]() Grigoropoulos VG, Williamson TH, Kirkby GR, Laidlaw DA. Management of degenerative retinoschisis-associated retinal detachment. Anesthesia for nonobstetric surgery in the pregnant patient. 775: Nonobstetric surgery during pregnancy. In a pregnant patient with a chronic-appearing retinoschisis-associated retinal detachment, one can consider close monitoring for progression of detachment and delay surgical repair until safe delivery. Surgery in a pregnant patient needs to be coordinated with the obstetrics team and anesthesia providers, balancing the urgency of surgery, risks of delay and risks to the pregnancy. On subsequent postoperative visits, the retina remained attached. We then applied endolaser around the retinotomy and throughout the retinal schisis cavity. ![]() We drained the subretinal fluid through a drainage retinotomy at 8 o’clock using soft-tip extrusion, then noted a flattening of the retinal schisis cavity. We applied endodiathermy to mark the areas of thinning. During the case, we did not note any distinct break with scleral depression, but we did observe thinning over the schisis cavity. We also considered the potential challenges with positioning because she was a first-time mother of a newborn. We elected a scleral buckle combined with a vitrectomy and gas tamponade (15% C 3F 8) because of the chronic-appearing cavity and inferior location. No consensus exists regarding the best surgical methods to repair retinoschisis-associated retinal detachments, although various methods of repair have been employed. While observation may be appropriate in some cases of retinoschisis-associated retinal detachments, which can often remain stable and asymptomatic long-term, surgical repair is typically required in the setting of progressive symptoms. Surgical repair was undertaken six weeks after initial presentation (two weeks postpartum). 2īecause this patient was so close to her due date and had an acute-on-chronic appearing retinal detachment, we elected to delay the repair until after delivery, with consultation from her obstetrics team.įrom the time of diagnosis to surgery, we followed her with weekly exams and fundus photography for documentation, which demonstrated only minimal progression of her detachment. Obstetric surgery in a pregnant patient is the second trimester, when the risk of preterm labor is lower compared to the third. However, pregnant women should not be denied medically necessary surgery at any trimester. The American College of Obstetrics and Gynecology recommends delaying elective surgery until after delivery. Timing of surgical repair was complicated by the fact that the patient was in her third trimester of pregnancy.
