central serous chorioretinopathy

The frst results of combined treatment of central serous chorioretinopathy using subthreshold micropulse laser exposure with 577 nm wavelength and injections of platelet autoplasma

Summary:

Aim: to compare the efects of a combination of subthreshold micropulse laser irradiation (SMPLI) with injections of autologous platelet plasma (PP) in the region of the pterygopal fossa on the afected side with the efect of SMPLI in central serous chorioretinopathy (CSСR). Material and Methods. This study was conducted on 60 patients (60 eyes) with CSCR. Patients were divided into 2 groups: in the comparison group patients received treatment only with SMPLI with a wavelength of 577 nm. In the experimental group patients received SMPLI with TP injections. TP was started after 72 hours, with 3 injections into the area of pterygopalatine fossa in the afected eye, with an interval between injections of 72 hours. Ophthalmologic examination, OCT and fuorescent angiography were carried out before treatment and 1, 3, 6 and 12 months after treatment, and ELISA assessment of IL-4, — 6 and -17A levels in lacrimal fuid was performed. Results. In the experimental group, where SMPLI+TP were performed, visual acuity has signifcantly improved, thickness of central section of macula was noted to have been decreased, and photosensitivity of central zone of retina signifcantly improved when compared to the SMPLI group. In the SMPLI+TP group the levels of IL-4, IL-6 and IL-17A in tear fuid increased. SMPLI was performed using Supra 577 nm laser device (Quantel Medical, France) over the entire area of macular edema. Conclusion. SMPLI+PRP treatment in patients with acute CSCR is efective for restoration of visual function.

Summary:

Purpose: to determine the efectiveness of above-threshold (focal) laser coagulation and micropulse laser exposure (MPLV) in patients with central serous chorioretinopathy (CCA). Material and Methods. 91 people with a diagnosis of CCA were examined. The median age was 35.2 years. Patients of the 1st group (n=19) was performed MPLV a wavelength of 810 nm; group 2 (n=31) — about threshold photocoagulation with the wavelength of 810 nm. Control group — 50 people with a natural course of the process. Results. After 1 month after treatment in group 1, visual acuity increased from 0.5±0.08 to 0.8±0.03. According to optical coherence tomography (OCT), the neuroepithelial detachment decreased from 446 to 341.3 MK. With the chronic course of the process after laser treatment, recurrence of the disease was revealed, which required an additional session of MPLV. In group 2, after 1 month, visual acuity increased from 0.6±0.20 to 0.8±0.03, neuroepithelial detachment decreased from 365 to 269 MK. Relapse of the disease in chronic form required an additional session of MPLV. After 3 months, both groups showed complete adhesion of the neurosensory retina and increased visual acuity to 0.9±1.0. Conclusion. Laser coagulation (above- threshold laser coagulation, micropulse laser exposure) is minimally invasive and highly efective in the treatment of central serous chorioretinopathy. The choice of laser treatment method depends on the

The possibilities of optical coherence tomography in En Face mode in planning and conducting computer-assisted laser surgery for central serous chorioretinopathy

Year: 2019, volume 15 Issue: №2 Pages: 433-442

Summary:

Purpose: to assess the diagnostic capabilities of optical coherence tomography (OCT) in En Face mode for planning and conducting surgical navigation using Navilas 577s laser system in patients with central serous chorioretinopa-thy (CSC). Material and Methods. 12 patients (12 eyes) with CSC underwent high-resolution OCT in En Face mode showing morphological changes in the retinal pigment epithelium (RPE). The treatment was performed on Navilas 577s laser device with an individual selection of the necessary energy parameters in the micropulse mode. The follow-up was performed at 1, 3 and 6 months. Results. According to the OCT data in the En Face mode, all patients had morphological changes in RPE, which made it possible to plan and perform computer-assisted laser surgery. 1, 3 and 6 months after treatment, positive dynamics was observed in all cases. Conclusion. The OCT method in En Face mode allows detailed study of architectonics and identifes pathological changes in RPE, which play an important role in the manifestation of CSC, as it enables planning and implementation of topographic-oriented treatment using the Navilas 577s navigation laser system in the areas of RPE detachments.
