Purpose There is no widely accepted treatment for persistent/chronic central serous chorioretinopathy. The present study aimed to evaluate the efficacy, safety, and factors associated to treatment response to navigated micropulse laser in chorioretinopathy. Methods Retrospective observational case series including consecutive patients presenting with symptomatic persistent and chronic chorioretinopathy. All patients were treated with 5% navigated micropulse laser with the Navilas system (Navilas®, OD-OS GmBH, Teltwo, Germany), by overlying fluorescein angiography, indocyanine green angiography and/or spectral domain-optical coherence tomography images of visible leaking points and/or choroidal hyperpermeability/subretinal fluid to plan the laser treatment. Results Thirty-nine eyes of 36 consecutive patients (29 men and 7 women, with a mean age of 51.87 years) were included. Logarithm of the minimum angle of resolution (LogMar) best-corrected visual acuity increased from 0.39 ± 0.24 at baseline to 0.24 ± 0.22 at 3 months ( p < 0.0001) and to 0.20 ± 0.07 at 6 months ( p < 0.0001). Subretinal fluid decreased from 166.82 ± 111.11 micron at baseline to 52.33 ± 78.97 micron ( p < 0.0001) at 3 months and 34.12 ± 67.56 micron at 6 months ( p < 0.0001). The presence of a hot spot on fluorescein angiography and a focal choroidal hyperpermeability on indocyanine green angiography, but not the duration of symptoms correlated significantly with the resolution of subretinal fluid at month 3 ( p = 0.023 and p  = 0.001). Conclusion Navigated micropulse laser laser treatment was found to be effective and safe for the treatment of chorioretinopathy, with significant improvement in visual and anatomical outcomes, unaccompanied by any adverse event at 3 and 6 months follow-up. Factors associated to subretinal fluid resolution may allow a better selection of likely responders to navigated micropulse laser treatment.

Purpose: The aim is to discuss the efficacy of micropulse laser treatment in a patient suspected of polypoidal choroidal vasculopathy. Case Presentation: A 61-year-old male patient presented with decreased vision in his left eye. He had a dome-shaped lesion below the macula and macular swelling in the fundus examination. Optical Coherence Tomography (OCT) showed neurosensorial serous detachment of the macula and polypoid appearance in the region consistent with the dome-shaped lesion. The patient was recommended Flourescein Angiography (FA), indocyanine green angiography (ICGA), but for economic reasons he refused to perform ICGA. After that, only FA was performed. As a result of the examinations, it was evaluated as central serous chorioretinopathy by a retina specialist. Three months later, because of subretinal fluid persistence, micropulse laser treatment including polyp-like lesion was applied. Results: At the 6th month follow-up, it was found that the fluid completely regressed and the Pigment Epithelial Detachment (PED) appearance occurred in place of the polypoidal appearance in OCT. In the 22nd month, subretinal fluid disappeared completely and PED appearance was observed. Conclusions: Although the characteristics of OCT of this case is similar to the OCT appearance in PCV, it would be more reasonable to consider this case as CSC in the light of current information, as this case responded to MPL treatment. Therefore, prospective studies with large groups are needed.

Background: It has been recommended that any invasive treatment performed in patients with central serous chorioretinopathy (CSCR) not be initiated earlier than four months after disease onset due to the potential for spontaneous remission of symptoms. The goal of this study was to examine the outcome of transfoveal subthreshold micropulse laser treatment (SMPLT) of CSCR performed at six months or less after disease onset. Materials and methods: The study included 32 cases of CSCR lasting between three weeks and six months (mean: 3.4 ± 2.3 months). All patients had transfoveal SMPLT applied and were followed for at least three months after each session of SMPLT. Two sessions of SMPLT in total were planned in case of an insufficient response to the first instance of treatment. Evaluation parameters included any change in best-corrected visual acuity (BCVA) and retinal morphology. Results: Total resolution of subretinal fluid (SRF) was noted in 26 cases (81.25%). Final BCVA improved significantly from 0.37 ± 0.22 logMAR to 0.22 ± 0.20 logMAR after treatment. Overall, early SMPLT correlated with better final BCVA (p = 0.0005, Spearman rank correlation). For eyes achieving a total resolution of SRF, BCVA improved from 0.33 ± 0.21 logMAR to 0.17 ± 0.14 logMAR (p = 0.004, Spearman rank correlation). The analysis of SMPLT nonresponders revealed a tendency for poorer baseline visual acuity. Conclusions: Patients with CSCR lasting six months or less treated with transfoveal SMPLT achieve better functional results with early application of this procedure. As baseline BCVA predicts final visual acuity, earlier treatment, permitted by the safety of SMPLT, may improve final visual outcomes.

Purpose — to study the morphological changes of the retinal pigment epithelium (RPE) by optical coherence tomography-angiography (OCT-A) in En Face mode before and after selective micropulse laser irradiation in patients with central serous chorioretinopathy (CSC), determine the correspondence between the topographic location of RPE defects and detachment on the OCT-angiogram in En Face mode and points of leakage on the FAG.Patients and methods. There were 20 patients (21 eyes) with CSC before and after laser treatment under the observation. All patients underwent high-resolution FAG and OCT-A using Angio Retina 2×2 or 3×3 mm protocol and Angio Retina HD 6×6 mm. The treatment was carried out in a selective micropulse mode with individual selection of parameters using the Navilas 577s navigation laser system (OD-OS, Germany) or the IQ 577 laser system (IRIDEX, USA).Results were evaluated at 2 weeks and 1 month after treatment. Results. In all cases, the leaking points of the subretinal fluid on FAG corresponded to the topographic location of defects and detachments of RPE detachment on OKT-A En Face. According to OCT-A En Face, the following morphological changes were revealed: in 5 cases — single defects of RPE, in 7 cases — multiple defects of RPE, in 9 cases of slit-like detachment of RPE, in 3 patients a combination of slit-like detachment and defect RPE. The sizes of RPE defects varied in the range from 21 to 159 microns, while their rounded shape prevailed. 1 month after the selective micropulse laser effect on OCT-A in the En Face mode, the defects were closed and the RPE detachments fit in all patients, which resulted in resorption of the subretinal fluid and the neurosensory retina attachment.Findings. OCT-A in En Face mode is a highly informative diagnostic method that allows noninvasive detection of morphological changes in RPE with a clear topographic localization relative to the retinal vascular network, as well as evaluating the effectiveness of selective micropulse laser treatment in patients with CSC.

In Behcet's disease, the anterior and posterior segments of the eye may be affected separately or together. Fundus fluorescein angiography should be performed in addition to ophthalmoscopic examination for early diagnosis and treatment of ocular involvement. Fundus fluorescein angiography (FFA) is the gold standard for the evaluation of the retinal vascular system and pathologies. Fundus fluorescein angiography is more sensitive than fundus examination in the detection of vasculitis, and angiographic involvement is always more common than clinical involvement. Fluorescein angiography may reveal leakage from retinal veins in eyes whose visual impression is not affected and the fundus examination is normal. The absence of vascular leakage with fluorescein angiography indicates that the disease is in a completely inactive period. Because of the development of blindness due to posterior segment involvement, early detection of the disease with fundus angiography and the initiation of the treatment is successful in terms of visual prognosis. It has an important place in terms of early activation of patients with FFA in the early diagnosis of eye involvement and follow-up of the disease and treatment. Wide-field imaging angiography imaging of the retinal periphery revealed the importance of lesions in retinal periphery and peripheral areas invisible by standard angiography. The use of indocyanine green angiography in Behcet uveitis is limited.

BackgroundTo describe clinical and imaging characteristics of patients presenting with diabetic retinopathy (DR) with coexisting acute or chronic central serous chorioretinopathy (CSCR).MethodsThis was a cross-sectional study which included 54 eyes of 27 patients with coexisting DR and CSCR. Demographic details, prior history of laser, best-corrected visual acuity (BCVA), central macular thickness (CMT), height of neurosensory detachment (NSD), subfoveal choroidal thickness (SFCT), subfoveal large choroidal vessel layer thickness (SF-LCVT), fluorescein angiography and indocyanine green angiography features were recorded. Subanalysis was done for patients with unilateral CSCR. Data was evaluated using Student t-test for quantitative data and χ2 test for qualitative data. CSCR between different grades of DR was analysed using analysis of variance.ResultsPrevalence of coexistent CSCR in eyes with DR was 0.4%. Mean age was 53.96±8.79 years, with 25 males. Mean CMT was 349.2±258 μm. Mean SFCT and SF- LCVT of 38 eyes were 376.40±86 μm and 178.80±62.8 μm, respectively. Fifteen eyes had centre involving diabetic macular oedema. Subanalysis of patients with unilateral CSCR showed that the loss of inner segment-outer segment (IS-OS) integrity (p=0.001), photoreceptor footplates at the NSD roof (p=0.001) on optical coherence tomography and dilated choroidal vessels (p=0.05) on indocyanine green angiography were found more often in the CSCR eyes compared with their fellow eyes. Features of CSCR among the different grades of DR were not significantly different between the groups.ConclusionOur study describes features of a unique subset of patients presenting with coexistent DR and CSCR. Such coexistent nature needs special attention by the clinicians as this may change the treatment approach and alter outcomes.

Choroidal Vasculopathy

Abstract Polypoidal choroidal vasculopathy (PCV) is a common choroidal vascular disease particularly in Asians. However, the underlying pathogenesis of PCV is still yet to be fully elucidated, and the correlation between choroidal vasculature and treatment response of PCV are poorly understood. Accordingly, we sought to find clues to understand the pathogenesis and prognosis of PCV by quantitatively evaluating choroidal vasculature from the entire fundus using ultra-widefield (UWF) indocyanine green angiography (ICGA). In this study, 32 eyes from 29 patients with treatment naïve PCV and 30 eyes from 30 healthy control participants were enrolled. Choroidal vascular density (CVD) of PCV eyes was higher than normal eyes in majority regions including the periphery. CVD was positively correlated with choroidal thickness and choroidal hyperpermeability, supporting that the pathogenesis of PCV may include choroidal congestion and dilatation. Thicker choroid and higher CVD were also correlated with poor treatment response after anti-VEGF injections. The CVD, quantified from UWF ICGA can also be used as an effective image biomarker to predict the treatment response in PCV.
