[PMID: 32908883 PMCID: PMC7450301 DOI: 10.1155/2020/3190136] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/22/2020] [Revised: 07/02/2020] [Accepted: 07/27/2020] [Indexed: 11/18/2022]
Abstract
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.

Five-year follow-up of fundus autofluorescence and retinal sensitivity in the fellow eye in exudative age-related macular degeneration in Japan. PLoS One 2020; 15:e0229694. [PMID: 32142523 PMCID: PMC7059919 DOI: 10.1371/journal.pone.0229694] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/08/2019] [Accepted: 02/11/2020] [Indexed: 11/18/2022] Open
Abstract
PURPOSE To assess the 5-year change in abnormal fundus autofluorescence (FAF) patterns and retinal sensitivity in the fellow eye of Japanese patients with unilateral exudative age-related macular degeneration (AMD). METHODS Patients with unilateral exudative AMD who developed abnormal FAF in the fellow eyes were enrolled. FAF imaging and microperimetry were performed at baseline and follow-ups. FAF findings were classified into 8 patterns based on the International Fundus Autofluorescence Classification Group to assess retinal sensitivity. Forty-five points covering the central 12 degrees on microperimetry were superimposed onto the FAF images. Each point was classified depending on the distance from the abnormal FAF. "Close" was defined as the portion within 1 degree from the border of any abnormal FAF, and "Distant" was defined as the portion over 1 degree from the border of abnormal FAF. To investigate the association between the retinal sensitivity and distance from the abnormal FAF, hierarchical linear mixed-effect models were used with the distance, time and time squared from baseline (months), and angle (degrees) as fixed effects. Differences among patients, eyes, and test point locations were considered successively nested random effects. RESULTS We studied 66 fellow eyes with abnormal FAF. Twenty-seven eyes were followed-up during the 5 years. In the 13 of 27 eyes (48%), the abnormal FAF patterns had changed during the 5 years. We found retinal sensitivity was associated significantly with the distance from the abnormal FAF ("Distant": p<0.001, time2 from baseline: p<0.001, angle: p<0.001). The mean retinal sensitivity of the "Close" tended to deteriorate after the third year and eventually showed the similar sensitivity as the portion within the abnormal FAF. CONCLUSION FAF patterns can change about half during the 5 years and the retinal sensitivity near abnormal FAF tends to deteriorate after the third year.

Inverted internal limiting membrane-flap technique for large macular hole: a microperimetric study. Int J Retina Vitreous 2019; 5:44. [PMID: 31641530 PMCID: PMC6798391 DOI: 10.1186/s40942-019-0195-6] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/05/2019] [Accepted: 10/10/2019] [Indexed: 02/02/2023] Open
Abstract
Background Inverted Internal Limiting Membrane (ILM)-flap technique would seem to lead to higher closure rate and better visual acuity than traditional procedure with ILM peeling for the treatment of large macular hole (LMH). Visual acuity recovery does not reveal many other functional changes related to surgical approach. Our purpose was to evaluate macular function and morphology over a 1-year follow-up after inverted ILM-flap technique for LMH by using microperimetry in order to predict visual prognosis. Methods This study was a prospective unrandomized single-center study. 23 eyes of 22 patients with idiopathic LMH, with a minimum diameter ranging from 400 to 1000 μm, were included. All patients underwent vitrectomy with inverted ILM-flap technique and gas tamponade. We analyzed macular hole closure rate and functional outcomes including best-corrected visual acuity (BCVA), macular sensitivity (MS) at central 12° and central macular sensitivity (CMS) at central 4°, and fixation behavior as bivariate contour ellipse area (BCEA, degrees2) at 68%, 95%, and 99% of fixation points measured by microperimeter, over a follow-up of 12 months. Results The macular hole closure rate was 98%. The BCVA improved from 20/230 (Logmar, 1.06 ± 0.34) to 20/59 (logMar, 0.47 ± 0.45) at last follow-up (p < 0.001). Retinal sensitivity and BCEA significantly improved (MS, p = 0.001; CMS, p < 0.0001; BCEA: 68%, p < 0.01; 95%, p < 0.01; 99%, p = 0.001). Multiple stepwise regression analysis showed the final BCVA was significantly associated with macular hole size (β = 0.002, p = 0.03), preoperative MS (β = − 0.06, p = 0.001) and BCEA at 95% and 99% of fixation points (β = − 0.12, p = 0.01; β = 0.06, p = 0.01). Conclusions Inverted ILM-flap technique for LMH results in good morphologic and functional outcomes. Macular hole size and microperimetric parameters as preoperative MS and BCEA have a predictive role on post-surgical visual acuity.

Abstract
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.

Abstract
The purpose of the current study was to investigate the association between visual function and retinal structure in central serous chorioretinopathy (CSC). In 22 eyes of 22 chronic CSC patients with serous retinal detachment at the macula, retinal sensitivity was measured using MP3 microperimetry (NIDEK, Japan) and mean sensitivity within two degrees (MS2), four degrees (MS4) and six degrees (MS6), as well as foveal sensitivity (MS0), were calculated. Retinal structure was measured using optical coherence tomography (OCT, Spectralis, Heidelberg). The relationship between visual function (LogMAR best-corrected visual acuity [LogMAR VA] and MS0, MS2, MS4, MS6) and serous retinal detachment height at the fovea (SRDH), central retinal thickness (CRT), macular volume (MV) and central choroidal thickness (CCT) was investigated. There were significant negative correlations between LogMAR VA and MS0 (p = 0.016), MS2 (p = 0.049). No significant relationship was observed between LogMAR VA and SRDH (p = 0.97) although there was a significant negative correlation between SRDH and MS2 (p = 0.028), MS4 (p = 0.049), MS6 (p = 0.023). In conclusion, in CSC, serous retinal detachment was significantly correlated with retinal sensitivity measured with MP3, but not with LogMAR VA.

Abstract
BACKGROUND To evaluate the macular sensitivity changes after half-dose photodynamic therapy (PDT) for chronic central serous chorioretinopathy (CSCR). METHODS Eighteen patients (26 eyes) with chronic CSCR were recruited in the same hospital between April 2011 and December 2012. All patients were treated with one session of half-dose PDT after complete ophthalmic examination. Macular sensitivity examination was performed at baseline and 1, 3 and 6 months post-treatment. Mean sensitivity (MS) of the central 10 degrees (10°) and 4 degrees (4°), mean deviation (MD) and pattern standard deviation (PSD) on automated static perimetry (Humphrey Field Analyzer II-750) were used for analysis. RESULTS There was significant improvement of the 10°MS from baseline (29.76 ± 1.51 dB) to 1 month (31.74 ± 1.56 dB), 3 months (31.51 ± 1.38 dB) and 6 months (31.19 ± 1.61 dB) after treatment (P < 0.001). The 4°MS was also significantly improved with half-dose PDT from baseline (28.96 ± 1.78 dB) to 1 month (32.41 ± 1.66 dB), 3 months (32.46 ± 1.50 dB) and 6 months (31.90 ± 1.84 dB) post-treatment (P < 0.001). MD was improved from baseline (-3.39 ± 0.89 dB) to 1 month (-1.96 ± 0.29 dB), 3 months (-1.94 ± 0.29 dB) and 6 months (-2.45 ± 0.13) post-treatment (P = 0.004). PSD also improved from 1.97 ± 0.24 dB at baseline to 1.47 ± 0.27 dB, 1.34 ± 0.24 dB, and 1.53 ± 0.24 dB (P = 0.001) at 1, 3 and 6 months after treatment, respectively. CONCLUSION Macular sensitivity in CSCR can be improved by half-dose PDT, along with improvement of visual acuity and retinal thickness. The treatment outcome at 1 month may be a predictor of the final treatment response.

Abstract
INTRODUCTION Macular disease is the leading cause of low vision in the Western world. Drusen and pigmentary irregularities are common among the rural Northern Indian population. The disease process leads to loss of central vision, metamorphopsia, macropsia or micropsia and colour vision defect. AIM To study the retinal sensitivity changes in macular diseases using microperimetry. MATERIALS AND METHODS It was an observational study, conducted in the Department of Ophthalmology at a rural tertiary care hospital. This study was started from December 2014 until June 2016, in all patients with macular disease above the age of 20 years attending the outpatient department. Microperimetry was done for 84 eyes of 52 patients with macular disease. Mean retinal Sensitivity (MS) and fixation stability was evaluated. The statistical analysis of mean retinal sensitivity, central 2° and 4° fixation was done by calculating the mean and standard deviation using 95% confidence interval. RESULTS The range of age was between 20-81 years. Majority were 32 males (62%) and 20 females (38%). Out of the 84 eyes studied, majority of the macular disease were Age-Related Macular Degeneration (AMD) (50%). Rest 50% were other macular diseases. The mean retinal sensitivity (dB) shown by microperimetry was 10.83 in AMD, 9.12 in Cystoid Macular Oedema (CME), 10.34 in Epiretinal Membrane (ERM), 10.74 in Pigment Epithelial Detachment (PED), 8.96 in Central Serous Chorioretinopathy (CSCR), 6.43 in macular dystrophy, 7.15 in Lamellar Hole (LMH), 9.8 in Pseudomacular Hole (PMH), 3 in geographic atrophy, 11.1 in macular telangiectasia, 5.6 in Berlin oedema, 12.3 in macular scar and 15.2 in haemorrhage in macula. The study showed 64% of the eyes had stable 2° central fixation, 35% had relatively unstable fixation and 1% had unstable fixation. No significant correlation between retinal sensitivity and retinal thickness in AMD was found. CONCLUSION This study shows that microperimetry can be a useful tool for objective evaluation of macular function and progression of the disease.

Abstract
Objective To study the macular sensitivity after half-dose verteporfin photodynamic therapy in patients with resolved central serous chorioretinopathy using the automated static perimeter. Methods Prospective consecutive case study of 24 patients with resolved central serous chorioretinopathy was performed. The macular sensitivity was measured using a conventional automated static perimeter with the Swedish interactive threshold algorithm 10-2 and foveal threshold. Best corrected visual acuity, intraocular pressure, fundus examination, macular thickness, and volume were also examined. The mean macular sensitivities of the affected eyes and their normal fellow eyes were calculated and compared. P<0.05 was considered statistically significant. Results The mean macular sensitivities of the affected eyes were lower than the normal fellow eyes with a statistically significant difference in all areas of the study (P<0.05). Best corrected visual acuity improved significantly from pretreatment (0.26±0.3 logMAR) to posttreatment (0.075±0.15 logMAR, P<0.05). Macular thicknesses in affected eyes were 230.66±67.34 μm and in the normal eyes were 238.33±92.26 μm (P=0.68). Macular volumes in affected eyes were 8.77±0.49 and in the normal eyes were 8.70±0.50 (P=0.60). These findings were not statistically significant. Conclusion Eyes with resolved central serous chorioretinopathy after half-dose verteporfin photodynamic therapy had lower macular sensitivity than normal fellow eyes. These findings agreed well with the previous microperimetric studies. The conventional automated static perimeter can also be used when a microperimeter is not available.

Abstract
AIMS To define factors that determine the location and stability of fixation in patients with neovascular age-related macular degeneration (NV-AMD) treated with intravitreal ranibizumab injections. METHODS The location and stability of fixation using microperimetry were determined in 77 eyes treated with ranibizumab for NV-AMD for at least 12 months. All patients were treated with three injections of ranibizumab 0.5 mg, 1 month apart and retreated according to predefined criteria. The fixation parameters were correlated to the visual acuity, and quantitative measures on OCT. RESULTS The location of fixation was predominantly central in 52.6%, poor central fixation in 9.2%, and predominantly eccentric fixation in 38.2%. The fixation was stable in 65%, relatively unstable in 25%, and unstable in 10%. Visual acuity was the only factor that determined the stability and location of fixation. The characteristics of fixation were not related to the macular thickness or volume as measured by OCT. CONCLUSIONS Better visual outcome ensures central and stable fixation. Quantitative measures of OCT parameters do not determine fixation. Further studies on morphological features of the macula may provide some insight into the determinants of fixation.

Abstract
PURPOSE To investigate the relative involvement of chromatic and achromatic visual subsystems in central serous chorioretinopathy, and to correlate the function changes with the changes of the foveal photoreceptor layer using Fourier domain optical coherence tomography (FD-OCT). METHODS Central serous chorioretinopathy patients and control subjects were tested and compared. Equiluminant Chromatic sinusoidal gratings were presented in a pattern onset-offset mode. We measured the distance between the internal limiting membrane (ILM) and the external limiting membrane (ELM) on FD-OCT images. RESULTS Visual evoked potential mean latency was delayed significantly in central serous chorioretinopathy patients compared to controls. The visual evoked potential delay was greater for chromatic than for achromatic stimuli. Retinal thickness from ILM to ELM was associated significantly and selectively with short-wavelength-sensitive (S) cone visual evoked potential latency (r = -0.40, p = 0.032). CONCLUSIONS These results are consistent with data that indicate the loss of photoreceptors in central serous chorioretinopathy resulting in a reduced thickness of the outer nuclear layer. Additionally, they are consistent with data which indicate that the photoreceptor loss is relatively greater in cones. The S-cone pathway was affected the most.

Abstract
PURPOSE To evaluate the effect of half-dose verteporfin photodynamic therapy (PDT) on macular function in cases of central serous chorioretinopathy (CSC). DESIGN Interventional case series. METHODS A total of 24 eyes from 24 cases of CSC were included in this study. In each eye, at baseline and 1, 3, and 6 months after half-dose PDT, logMAR best-corrected visual acuity (BCVA); central 10-degree, 20-degree, and paracentral 10-degree to 20-degree retinal sensitivity; and also mean retinal sensitivity results for each case over the area that was treated with half-dose PDT (PDT spot area) by MP-1 microperimetry and optical coherence tomography (OCT) foveal morphologic changes were assessed. The MP-1 microperimetry sensitivity map was overlaid onto an indocyanine green angiography image recorded on a Heidelberg scanning laser ophthalmoscope using dedicated MP-1 software to evaluate the PDT laser spot area. RESULTS After treatment, BCVA and central 10-degree, 20-degree, paracentral 10-degree to 20-degree, and PDT laser spot area retinal sensitivity were improved significantly. In OCT in 20 of 24 eyes (83%), subretinal fluid (SRF) was resolved 1 month after half-dose PDT. At 3 and 6 months after treatment, SRF was resolved at all eyes. None of the patients in this study developed any systemic or ocular adverse events associated with verteporfin treatment. CONCLUSION Half-dose verteporfin PDT induced a significant increase in central 10-degree, 20-degree, paracentral 10-degree to 20-degree, and also PDT laser spot area retinal sensitivity over 6 months in cases of CSC.
