Purpose. To investigate retinal sensitivity characteristics associated with morphologic changes in the eyes exhibiting chronic central serous chorioretinopathy (CSC), using macular integrity assessment (MAIA) microperimetry. Methods. A retrospective, cross-sectional, observational study was constructed. The eyes of patients classified as chronic CSC, according to the onset of subjective symptoms with serous retinal detachment, as confirmed by optical coherence tomography examination, were included in the study. Retinal sensitivity and fixation were analyzed by performing microperimetry examinations using the MAIA instrument. Results. We reviewed microperimetry examinations of 15 eyes of 15 patients (age: 28–51 years) with chronic CSC and mean best-corrected visual acuity of −0.2 logMAR units. The mean retinal integrity in the chronic CSC group was 49.0 ± 27.6, which was significantly different from the control eyes. The mean average threshold in the eyes with chronic CSC was 24.7 ± 5.8 dB, which also was significantly different from the control eyes. Fixation stability was significantly different between the CSC and control eyes for the P1 parameter (90.1 ± 13.7 versus 99.3 ± 1.5), and for the P2 parameter (97.4 ± 4.0 versus 100.0 ± 0.0). Conclusion. New microperimetry technology may provide valuable information regarding the visual status of chronic CSC cases. Our findings suggest that retinal sensitivity and fixation stability in chronic CSC eyes may serve as useful indicators for assessing the effectiveness of clinical treatments.

The purpose of this study was to evaluate the long-term effects of half-time photodynamic therapy (PDT) on the retinal sensitivity in eyes with chronic central serous chorioretinopathy (CSC). Twenty-two eyes of 22 patients with chronic CSC were studied. PDT was applied with full-dose verteporfin and half-time laser duration. The best-corrected visual acuity (BCVA) and retinal sensitivity in the central 2 and 10 degrees were evaluated at the baseline, and at 12 and 24 months after the half-time PDT. The retinal sensitivity was determined by Macular Integrity Assessment microperimetry (MAIA, Centervue, Padova, Italy). The results showed that the mean retinal sensitivities in the central 2 and 10 degrees were significantly improved at 12 months (25.6±2.79 dB, median; 26.11 dB, 25.6±2.25 dB, median; 25.65 dB, respectively; P<0.001) and at 24 months (26.3±2.62 dB, median; 27.38 dB, 26.6±2.21 dB, median; 27.45 dB, respectively; P<0.001) after the treatment compared to that at the baseline (19.2±3.93 dB, median; 19.34 dB, 20.9±2.92 dB, median; 20.9 dB, respectively). The BCVA was also significantly improved from 0.18±0.19 median; 0.15 logarithm of the minimum angle of resolution (logMAR) units at the baseline to 0.07±0.15 median; 0 logMAR units at 12 months (P<0.001) and to 0.049±0.16 median; -0.039 logMAR units at 24 months (P<0.001). We conclude that half-time PDT results in a significant improvement of the mean central retinal sensitivity for at least 24 months in eyes with chronic CSC. Thus, half-time PDT is beneficial in resolving chronic CSC for a relatively long period.

Abstract Purpose To predict the change of retinal sensitivity using optical coherence tomography (OCT) parameters in eyes with central serous chorioretinopathy (CSC). Methods Twenty-three eyes of 23 patients with CSC were enrolled. Retinal sensitivity was measured twice with a microperimetry in all examined eyes. OCT measurement was simultaneously conducted. The relationship between retinal sensitivities and the thicknesses of i) retinal nerve fiver layer + ganglion cell layer (RNFL+GCL), ii) inner nuclear layer (INL) iii) outer nuclear layer (ONL) and iV) serous retinal detachment height (SRDH) were investigated in a point-wise manner. We also investigated the association between the change of retinal sensitivity and OCT parameters at baseline. Results The mean age of participants was 49.8 ± 10.7 years. The mean SRDH was significantly lower (p<0.001) and the mean retinal sensitivity (p<0.001) was significantly higher in the 2nd examination compared to the 1st measurements, however LogMAR visual acuity (VA) was not significantly different between the two measurements (p=0.063). LogMAR VA was associated with retinal sensitivity both in the 1st and 2nd measurements (p<0.001). The retinal sensitivity in the 2nd examination was significantly correlated with retinal sensitivity, RNFL+GCL, INL, ONL, SRDH in the 1st examination and the improvement of SRDH. Conclusions Retinal sensitivity was associated with retinal structure in eyes with CSC; these parameters were useful to predict the change of visual function before the treatment.

Purpose: The aim of this study was to evaluate the effect of half-dose verteporfin photodynamic therapy on central retinal sensitivity, status of fixation stability, and choroidal thickness in patients with chronic central serous chorioretinopathy. Methods: In total, 22 eyes of 22 patients with chronic central serous chorioretinopathy were enrolled, and all the eyes received indocyanine green angiography-guided half-dose verteporfin photodynamic therapy. Best-corrected visual acuity, contrast sensitivity, and retinal sensitivity in the central 10° and status of the fixation stability are assessed by MAIA microperimetry, and optical coherence tomography findings (central macular thickness and subfoveal choroidal thickness) were evaluated at baseline and 1, 3, and 6 months after the half-dose verteporfin photodynamic therapy. Results: Subretinal fluid was completely resolved in 9 eyes at 1 month and in 17 eyes at 3 months. There was recurrence in two eyes at 6 months and five of the eyes had a persistent subretinal fluid through all the time points. Best-corrected visual acuity, contrast sensitivity, and retinal sensitivity improved significantly 6 months after half-dose verteporfin photodynamic therapy. Fixation stability did not change in either follow-up visit. Central macular thickness and subfoveal choroidal thickness decreased significantly at 6 months of the visits compared to baseline. There was not any systemic and ocular side effect after the treatment. Conclusion: This study shows that there is significant improvement in best-corrected visual acuity, contrast sensitivity, and retinal sensitivity after half-dose verteporfin photodynamic therapy. The status of fixation stability remained unchanged in the eyes with chronic central serous chorioretinopathy after half-dose verteporfin photodynamic therapy. Furthermore, half-dose verteporfin photodynamic therapy is also effective in decreasing central macular thickness and subfoveal choroidal thickness.

Background: We study the retinal function measured by macular integrity assessment microperimetry (MAIA) and structural changes assessed by scanning swept source optical coherence tomography (SS-OCT) between healthy individuals and patients undergoing pars plana vitrectomy (PPV) after rhegmatogenous retinal detachment (RRD). Methods: Cross-sectional study. Early Treatment Diabetic Retinopathy Study (ETDRS) grids were measured by SS-OCT and compared with the MAIA parameters. Results: Thirty-eight eyes with RRD (19 macula-on and 19 macula-off) were compared with 113 healthy eyes. The retinal sensitivity and average total threshold were reduced in all sectors in the RRD group; macular integrity index was increased. Macular thicknesses in total retina and ganglion cell layer (GCL)++ protocols were higher in the RRD group in nasal outer (NO) and central (C) sectors and only in C sector for GCL+ protocol. Thicknesses were lower in total retina, GCL++ protocols in the temporal outer (TO) sector and in the GCL+ protocol in NO sector. Best-corrected visual acuity (BCVA) correlated moderately with retinal sensitivity in all sectors and in just several sectors with time between the date of surgery and the test. The central nasal (CN) sector thickness and the average total threshold were higher in the macula-on subgroup. Conclusions: RRD and subsequent surgery results in functional and structural changes, especially in individuals with macular detachment.

Background: Ocular complications of herpes zoster ophthalmicus (HZO) may lead to substantial visual disability, severe post-herpetic neuralgia and rarely fatal cerebral complications. Aim: To identify the pattern of ocular manifestation in herpes zoster ophthalmicus. Materials and methods: A cross-sectional descriptive study was under taken including the clinically diagnosed cases of HZO. All of them underwent a complete ophthalmological evaluation. Results: Sixty-eight cases of HZO were examined, of which 37 (54.4 %) were male and 31 (45.6%) female. The mean age was 48.7 ± 18.5 years. Most of the patients (64.7 %) were above the age of 40 years. 77.94 % of the patients had some form of ocular involvement. Pain (77.9 %) was the commonest ocular complaint. In young patients less than 35 years, HIV was the most common risk factor (19.3 %).Visual status was good in the majority (73.5 %) of patients at presentation. Lid and adnexal findings (45.8 %) were most common ocular involvement followed by conjunctivitis (41.1 %). Corneal complication was seen in 38.2 % of cases, uveitis in 19.1 % and post-herpetic neuralgia (PHN) and secondary glaucoma each in 5.8 %. Conclusion: Eyelid and ocular adnexal involvement is most commonly found in patients with herpes zoster ophthalmicus followed by corneal complication and uveitis. There needs to be awareness of ocular involvement, which can be sight threatening, among the HZO patients and other medical departments and an increased emphasis on regular ophthalmic examination.

Imaging Characteristics

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.

BackgroundTo compare and correlate the retinal sensitivity measurements obtained with Nidek Microperimetry-3 (MP-3) and the CenterVue Macular Integrity Assessment (MAIA) microperimeters among healthy subjects.MethodsIn this prospective comparative study, 31 eyes of 23 subjects underwent complete ophthalmological examination including retinal sensitivity assessments using two microperimeters, the MP-3 (Nidek Technologies) and the MAIA (CenterVue). The mean retinal sensitivity (dB) and its corresponding luminance (asb) and contrast (log units) were analysed between the two instruments. The interdevice reproducibility and level of agreement between the sensitivity values of the devices were assessed.ResultsThe mean retinal sensitivity (dB) measured by the MP-3 (25.02±1.06 dB, range: 20.90–26.70) was significantly (p<0.0001) lower compared with the MAIA (30.68±0.74 dB, range: 28–31.84). The luminosity levels were significantly (p<0.0001) higher with the MP3 (7.75±1.31 asb, range: 6.44–9.06) compared with the MAIA (0.92±0.14 asb, range: 0.78–1.06). The contrast sensitivity was significantly higher for the MP-3 (0.94±0.33 log units, range: 0.61–1.27) compared with the MAIA (0.23±0.03 log units, range: 0.20–0.26). Despite these absolute differences, the intraclass coefficient was 0.85 (95% CI 0.70 to 0.92) between the two devices after applying a standard correction factor to each data point (MAIA sensitivity=MP-3 sensitivity+5.65) with a mean difference between MAIA and MP-3 of 0.01.ConclusionRetinal sensitivity measures higher, but luminance and contrast sensitivity measure lower for MAIA-generated values compared with the MP-3. The relationships, however, appeared fairly consistent, and application of a standard correction factor allowed the data to be inter-related, at least for normal eyes.

Purpose: The aim of this prospective clinical study was to evaluate the anatomical and functional results of the treatment of 54 eyes with chronic form of central serous chorioretinopathy (CSC) using photodynamic therapy in a reduced (half) verteporfin (HD-PDT) dosing regimen. Materials and Methods: Our prospective study included 54 eyes of 52 patients (40 males, 12 females) at an average age of 50.1 years (median 49.5, range 30–75 years) treated at the Ophthalmology Clinic of the First Faculty of Medicine and Military University Hospital in Prague from January 2012 to January 2018 for chronic form of CSC with a minimum disease duration of 3 months. In our study, we evaluated the improvement of the best corrected visual acuity (BCVA) and central retinal thickness (CRT) before treatment and at 1, 3, 6 and 12 months after HD-PDT. Results: The mean baseline BCVA was 68.91 ± 10.5 ETDRS letters (median 71; range 35–85) and the mean baseline CRT was 385.6 ± 118.5 µm (median 367, 5 µm; range 245–1000 µm). At the end of the follow-up period, the average BCVA was 79 ± 11 ETDRS letters (median 82; range 38–93). The improvement in BCVA before and after treatment was statistically significant in all measurements (p < 0.0001). The mean CRT at the end of the follow-up period was 263.5 ± 52 µm (median 258.5 µm; range 162–404 µm). The decrease in CRT at all timepoints was statistically significant compared to baseline (p < 0.0001). In our set of patients, at the end of the follow-up period, the retinal finding was improved or stabilized in 50 eyes (92.6 %). In this study, we observed in 2 cases the development of secondary choroidal neovascularization (CNV). Conclusion: HD-PDT is a long-term safe and effective method of treating chronic forms of CSC. However, despite a reduced dose of verteporfin, complications may occur.

Elevated fibrinogen levels is related to the blood hyperviscosity, that causes low blood velocity. Non-contrast-enhanced transcranialDoppler (TCD) is used to evaluate blood flow from the cerebrovascular system. To know the relationship between fibrinogen levels andexamination of TCD in acute ischemic stroke through evaluation. A cross sectional study was admitted from July 2012-Juny 2013.The researchers determined the differences between fibrinogen and TCD in the stroke group and control. The researchers examinedthe relationship between fibrinogen and TCD examination in the stroke group. The fibrinogenwas measured with Clauss method. TheTCD was examined due to middle of the cerebral artery (MCA) and the Internal Carotid one Artery (ICA). The patients were diagnosedas ischemic stroke from head CT-scan. Statistical analyses employed the Independent T test, Anova test and Pearson correlation. Theresearchers had 24 patients and 24 controls that the Fibrinogen levels in stroke group is 549.16±104.84 mg/mL and in the control groupis 385.64±16.80 mg/mL. The researchers examined MCA in the stroke as well as the control and found the mean velocity 43.12±21.03and 56.97±6.22 (p=0.05), the peak velocity 74.17±32.58 and 94.55±14.11 (p=0.05) end diastolic velocity 23.27±12.66 and35.30±7.34 (p=0.00). In ICA, the stroke group and control and found the mean velocity 31.40±8.86 and 43.07±8.06 (p=0.00), thepeak velocity 54.99±11.50 and 75.04±16.04 (p=0.00) end diastolic velocity 18.23±7.67 and 25.64±5.24 (p=0.00). The correlationbetween fibrinogen and TCD in the stroke group was not significant on MCA and ICA, P>0.05. It can be concluded that the differencesbetween fibrinogen levels and TCD in the stroke group and control are significant. But there is no correlation between the fibrinogenand TCD in the stroke group.
