RESUMEN
BACKGROUND: Subtenon injection of triamcinolone acetonide (STTA) has been widely adopted in the clinical setting of ophthalmology and its infectious complications are rare. However, orbital abscess following STTA has been reported in seven cases. Furthermore, although eye infections due to Exophiala species are uncommon, there have been 19 cases to date. E. jeanselmei, E. phaeomuriformis, E. werneckii, and E. dermatitidis have been reported to cause human eye infections; however, to the best of our knowledge, orbital abscess caused by E. dermatitidis has not yet been reported. We describe the first documented case of fungal orbital abscess caused by E. dermatitidis following STTA. We also review the related literature of orbital abscess following STTA, as well as eye infections caused by the four Exophiala species. CASE PRESENTATION: The patient was a 69-year-old Japanese woman with diabetic mellitus. She had a macular oedema in her right eye, which occurred secondary to branch retinal vein occlusion. An orbital abscess caused by E. dermatitidis occurred 4 months after the second STTA for the macular oedema, which was successfully treated by a surgical debridement and systemic administration of voriconazole. CONCLUSIONS: Our findings in the patient and from our literature survey caution ophthalmologists to the fact that STTA can cause fungal orbital infections, especially in diabetic patients. Furthermore, surgical treatment is one of the most important risk factors.

BACKGROUND Endocan is expressed in vascular endothelial cells, and its expression is enhanced following endothelial injury via inflammatory cytokines. Subsequently, endocan is secreted into the circulation. Thus, serum endocan levels are considered a marker of endothelial injury. However, to the best of our knowledge, no data on the serum endocan levels in peritoneal dialysis (PD) patients are available. MATERIAL AND METHODS This study included 21 PD patients who underwent peritoneal equilibration test (PET) more than once between 2011 and 2015. Serum samples were collected from each patient, and the 24-h urine volume was measured at the time of PET. Serum endocan levels were measured using enzyme-linked immunosorbent assay (ELISA) at the time of the first PET, and their relationship with clinical data or the extent of urine volume decline (mL/year) was analyzed retrospectively. RESULTS Serum endocan levels were positively correlated with proteinuria level, serum creatinine level, serum tumor necrosis factor (TNF)-α level, ß2-microglobulin level, and PD drainage volume, but not with urine volume at baseline. The extent of decline in urine volume was significantly associated with serum endocan level, proteinuria level, serum creatinine level, and serum TNF-α level at baseline in a simple linear regression analysis. Moreover, multiple linear regression analysis showed that the serum endocan level and proteinuria level at baseline were independent predictors for the extent of decline in urine volume. CONCLUSIONS The results of this study indicate that serum endocan level and proteinuria level may be useful predictive markers for decreased urine volume in PD patients.

PURPOSE: To investigate functional and morphological changes in patients with chronic central serous chorioretinopathy after supplementation with antioxidants containing lutein or a placebo. PROCEDURES: One hundred eyes of 100 patients were randomly divided into 2 groups, one taking tablets with lutein plus other antioxidants and the other taking a placebo for 6 months. Best-corrected visual acuity (BCVA) and the subfoveal fluid height on optical coherence tomography were measured. RESULTS: Seventy-nine patients (37 in the supplementation and 42 in the placebo group) completed the 6-month follow-up. In the supplementation group, mean BCVA showed significant improvement (p = 0.003), while there was no significant change in the placebo group (p = 0.589). The mean subfoveal fluid height was significantly reduced, by 28.6%, in the supplementation group (p = 0.028), in contrast to 3.3% in the placebo group (p = 0.898). CONCLUSIONS: Antioxidant supplementation significantly reduced subfoveal fluid height. The impacts of antioxidant supplementation on BCVA remain to be elucidated in future studies.

PURPOSE: To evaluate the 1-year results of intravitreal aflibercept injections for polypoidal choroidal vasculopathy based on indocyanine green angiography findings. METHODS: Twenty-nine eyes with treatment-naive polypoidal choroidal vasculopathy treated with intravitreal aflibercept injections and followed longer than 1 year were retrospectively reviewed. The best-corrected visual acuity, optical coherence tomography findings, and polypoidal lesions in indocyanine green angiography were evaluated. RESULTS: The mean number of injections through 1 year was 3.9 ± 1.9 (range: 1-8). Fourteen eyes (48%) were received no additional injections because of no recurrence of exudative change after the first loading dose. The mean best-corrected visual acuity levels at 6 months and 1 year significantly improved, and the mean central retinal thickness significantly decreased at all observation points from the baseline. At 3 months, the polypoidal lesions completely resolved in 19 (66%) eyes. At 1 year, the complete resolution of polypoidal lesions was seen in 4 of 10 eyes with persistent polypoidal lesions at 3 months. However, polypoidal lesions recurred at 1 year in 5 of 19 eyes (26%) with complete resolution of polypoidal lesions at 3 months. CONCLUSION: Aflibercept is effective for the eyes with treatment-naive polypoidal choroidal vasculopathy to achieve the resolution of polypoidal lesions. The authors need to carefully observe the eyes after confirming complete resolution of polypoidal lesion because of recurrent polyps seen in one-quarter of the study eyes.

PURPOSE: To describe the incidence and characteristics of neovascularization in fellow eyes of Japanese patients with unilateral retinal angiomatous proliferation (RAP). METHODS: We retrospectively studied patients with unilateral RAP in one center between 2003 and 2010. The minimal follow-up time was 2 years. The prevalence rates of soft drusen and reticular pseudodrusen in the fellow eyes at the first visit were examined in color fundus photographs and optical coherence tomography images. Stepwise analysis was performed to identify a correlation between the incidence of RAP in the fellow eyes and age, gender, follow-up time, soft drusen, and reticular pseudodrusen. RESULTS: Twenty eyes were included in this study. The mean follow-up time was 49 months (range, 24-108 months). At the first visit, soft drusen was seen in 19 eyes (95%) and reticular pseudodrusen in 11 eyes (55%). Neovascular age-related macular degeneration developed in 10 eyes, including RAP in 9 eyes (45%) and polypoidal choroidal vasculopathy in 1 eye (5%). Stepwise analysis showed that reticular pseudodrusen and longer follow-up time were correlated significantly (P = 0.0384 and P = 0.0341, respectively) with the incidence of RAP. CONCLUSION: Bilateral RAP developed in almost half of the eyes initially diagnosed with unilateral RAP and the incidence increased with time. Reticular pseudodrusen is a risk factor for bilateral RAP.

PURPOSE: To evaluate the effects of additional anti-vascular endothelial growth factor (VEGF) therapy for eyes with a retinal pigment epithelial (RPE) tear after anti-VEGF therapy and treated with additional anti-VEGF injections for recurrent or persistent exudative change. PATIENTS AND METHODS: Ten eyes (10 patients) followed up for >12 months after a recurrent RPE tear were evaluated retrospectively. The RPE tears on fundus autofluorescence images were measured and changes in the best-corrected visual acuity were evaluated. RESULTS: Patients were followed up for >12 months (mean, 27.3; range, 13-44 months). During 12 months of follow-up, additional anti-VEGF injections (mean, 3.3; range, 1-7) were administered. The mean size of the RPE tear at the onset was 6.5 mm² (range, 1.3-16.3 mm²). At 12 months, the RPE tear increased in size >20% in 5 eyes and remained unchanged or decreased in the remaining half of eyes. The mean logarithm of the minimum angle of resolution best-corrected visual acuity was 0.43 at the time the RPE tear developed and 0.85 at 12 months. The RPE tear grade and age were prognostic factors for best-corrected visual acuity at 12 months. CONCLUSION: Under continued anti-VEGF therapy, RPE tears may be stable in size and visual acuity could be maintained in some eyes; however, the visual acuity prognosis is still unsatisfactory in nonresponsive eyes.

PURPOSE: To investigate the choroidal thickness in eyes with tilted disk syndrome within/without posterior staphyloma. METHODS: Twenty-one eyes examined in 16 patients with tilted disk syndrome were included. The thicknesses of the choriocapillaris, the medium-to-large choroidal vessels, and total choroids found 1 mm and 3 mm superior and inferior to the fovea and in the area with the thinnest choroid were measured using enhanced-depth imaging optical coherence tomography or high-penetration optical coherence tomography. The results were compared with the findings on indocyanine green angiography. RESULTS: The mean thicknesses of total choroid found 3 mm and 1 mm inferior (114.3 µm ± 77.8 µm, 145.0 µm ± 85.9 µm) to the fovea were significantly thinner than those found superior (174.5 µm ± 89.7 µm, 145.0 µm ± 85.9 µm) to it. The minimal choroidal thickness of 80.5 µm ± 67.1 µm was obtained at a mean 1.04 mm below the fovea at the upper edge of the posterior staphyloma. The thickness of the layer of choriocapillaris was not significantly different according to the regions but the layer of medium-to-large choroidal vessels found 3 mm and 1 mm inferior to the fovea was significantly thinner than that found superior to the fovea. The ratio of choriocapillaris to medium-to-large vessels found 1 mm superior also was significantly smaller than those found inferior. The diameter of medium-to-large choroidal vessels on ICGA was not significantly different in the areas although less number of vessels were seen around the area inferior to the fovea. CONCLUSION: In the eyes of patients with tilted disk syndrome, the choroid is thinnest at approximately 1 mm inferior to the fovea at the upper edge of the posterior staphyloma rather than at the bottom of the posterior staphyloma. Thinning of the layer of medium-to-large choroidal vessels seems to be associated with the thinning of choroid thickness.

PURPOSE: To investigate the characteristics of central serous chorioretinopathy complicated by focal choroidal excavation (FCE) using fundus angiography and optical coherence tomography (OCT). METHODS: A retrospective single-institution study. We reviewed the charts of 7 eyes of 7 patients (5 men, 2 women; mean age, 56.9 ± 9.8 years) with central serous chorioretinopathy complicated by FCE using fundus angiography and OCT. RESULTS: In six of the seven eyes, the points of leakage were at the edge of FCE on OCT. All FCE lesions were hypofluorescent from early to late phase on indocyanine green angiography. All eyes had late-phase hyperfluorescence on indocyanine green angiography secondary to choroidal vascular hyperpermeability around the FCE lesion. Five fellow eyes also had choroidal vascular hyperpermeability. The mean subfoveal choroidal thicknesses by swept source high-penetration OCT were 377 µm and 333 µm in the fellow eyes, a difference that did not reach significance (P = 0.21). CONCLUSION: Fundus angiography and OCT showed that choroidal circulatory disruption and atrophic retinal pigment epithelium at the FCE lesion might be related to central serous chorioretinopathy complicated by FCE.

Purpose: To report two cases of diabetic macular edema (DME) treated with intravitreal faricimab injections (IVFs), including the assessment of retinal microaneurysms and extent of retinal capillary non-perfusion using fluorescein angiography (FA) and indocyanine green angiography (IA). Observations: Case 1: A 72-year-old man presented with aflibercept-resistant DME in the left eye, with a best-corrected visual acuity (BCVA) of 20/16. FA showed areas of retinal capillary non-perfusion and focal leakage in the macular area of the left eye. IA revealed numerous microaneurysms in the temporal region of the macula. Four consecutive monthly IVFs were administered to the left eye, and DME eventually diminished. After the loading phase, the BCVA was maintained at 20/16 with reduced visual distortion. FA showed improvement of macular leakage and stable retinal capillary non-perfusion areas, and the foveal avascular zone was clearly observed. The disappearance of numerous microaneurysms was confirmed on IA images.Case 2: An 80-year-old woman developed DME with macular vein occlusion in the left eye after panretinal laser photocoagulation for proliferative diabetic retinopathy. The patient's BCVA was 20/32. DME was resistant to subtenon triamcinolone injections. FA revealed focal areas of retinal capillary non-perfusion and persistent leakage in the macular area of the left eye. IA revealed scattered microaneurysms within the retinal arcade. Four consecutive monthly IVFs were administered to the left eye, and DME eventually diminished. After the loading phase, the BCVA was maintained at 20/32. FA showed improvement of macular leakage and stable retinal capillary non-perfusion areas. The reduction of microaneurysms was confirmed on IA images. Conclusions and importance: These case reports highlight the potential of faricimab as an alternative anti-vascular endothelial growth factor drug for treatment-resistant DME, including reduction of retinal microaneurysms and stabilization of the areas of retinal capillary non-perfusion. However, continuation of a robust treatment regimen may be required to achieve these objectives.
RESUMEN
PURPOSE: To compare macular pigment in three types of macular telangiectasia (MacTel). METHODS: Twenty-six eyes of 16 patients (mean age, 62 years) with MacTel were examined. The macular pigment optical density (MPOD) was obtained by autofluorescence spectrometry using two wavelengths (488 nm, 514 nm). The density of the central macular pigment within 0.5 degree around the foveal center (MPODc) was measured from a MPOD map. RESULTS: Eight eyes of seven patients were classified as type 1, 16 eyes of eight patients as type 2, and two eyes of one patient as type 3. The macular pigment signal was seen in the area of fluorescein leakage in type 1 and the occlusive area in type 3; the macular pigment signal decreased in the area of fluorescein leakage in type 2. The mean MPODc (± standard deviation) was 0.40 ± 0.16 density unit (DU) (range, 0.17-0.57) in type 1; -0.08 ± 0.15 DU (range, -0.29-0.25) in type 2; and 0.32 ± 0.08 DU (range, 0.26-0.37) in type 3. Significant differences were seen between types 1 and 2 (P < 0.001) and types 2 and 3 (P = 0.007). There was no significant difference between types 1 and 3 (P = 0.765). In 30 age-matched normal eyes, the MPODc was 0.58 ± 0.11 DU (range, 0.38-0.79). There were significant differences between normal eyes and each MacTel subtype (type 1, P = 0.007; type 2, P < 0.001; type 3, P = 0.043). CONCLUSIONS: The macular pigment values and distributions, including leakage or occlusion, differed in each MacTel type compared with fluorescein angiography findings. The capillary occlusion in type 3 is not associated with reduced MPOD.

PURPOSE: To investigate changes in fundus autofluorescence (FAF) during 3 years of follow-up in patients with polypoidal choroidal vasculopathy (PCV). DESIGN: Retrospective study. METHODS: We retrospectively reviewed the charts of 48 eyes of 47 patients (35 men, 12 women; mean age, 69.9 ± 7.1 years) with treatment-naïve PCV for whom FAF and indocyanine green angiography (ICGA) images were available at baseline and at 3 years ± 3 months follow-up examination. The main outcome measures were the FAF changes during 3 years of follow-up, and the correlation between them and polypoidal lesions and branching vascular networks on ICGA. RESULTS: The FAF of the polypoidal lesions showed three patterns at baseline and changes during 3 years of follow-up: confluent hypoautofluorescence surrounded by a hyperautofluorescent ring (86.1% â 51.4%), confluent hypoautofluorescence without a ring (8.3% â 43.0%), and no marked changes (5.6% â 5.6%). The FAF in 96.2% of resolved polypoidal lesions persisted on images with abnormal FAF during the 3 years of follow-up. The granular hypoautofluorescence at the branching vascular networks at baseline became partially confluent hypoautofluorescence in 41 eyes (85.4%). The mean area with confluent hypoautofluorescence that corresponded to the branching vascular network lesions increased significantly (P < 0.001) from 1.75 mm(2) to 5.10 mm(2) after 3 years of follow-up. CONCLUSION: The FAF changes in PCV during the 3 years of follow-up can indicate that FAF imaging is a useful and clinically beneficial tool for noninvasively evaluating the PCV lesions and disorders of the upper retinal pigment epithelium.

PURPOSE: To study the choroidal thickness profile using high-penetration optical coherence tomography in central serous chorioretinopathy (CSC). METHODS: Thirty-five eyes of 27 subjects with CSC and 35 healthy, age-matched control eyes were included. We observed the choroid using the prototype high-penetration optical coherence tomography. Fluorescein angiography and indocyanine green angiography were performed to identify the CSC location and activity. The choroidal thicknesses was measured manually in various conditions or locations, and the choroidal thickness maps were obtained from cube scans and calculating software and composed of nine sectors in the Early Diabetic Retinopathy Study chart. RESULTS: The subfoveal choroidal thicknesses in all eyes with CSC were significantly (P < 0.01) greater than that in the control eyes. The choroidal thickness at the fovea and the fluorescein points of leakage were significantly (P < 0.01 for both comparisons) greater in eyes with CSC than the corresponding locations in the fellow eyes in patients with unilateral disease. Dilatation of the choroidal large vessels was significantly (P < 0.01) more common in CSC. The foveal choroidal thickness was significantly greater in eyes with venous dilatation (P < 0.01) than those without. The mean choroidal thickness was significantly (P < 0.05) greater in all sectors of the Early Diabetic Retinopathy Study chart except for the inner (P = 0.087) and outer (P = 0.053) inferior sectors. The percent mean choroidal thicknesses compared with the normal controls in the nasal sector were significantly (P < 0.05 and P < 0.01, respectively) greater in the inner and outer circles than in the superior, temporal, and inferior sectors. CONCLUSION: The choroid is diffusely thickened in CSC likely because of the choroidal vascular dilatation. The nasal macula undergoes the greatest alterations in choroidal thickness compared with the other areas.

PURPOSE: Intravitreal injection of ranibizumab is highly effective for wet age-related macular degeneration. Its limitation is that most patients require repeated intravitreal injections to achieve and maintain the visual gain. We assessed the effectiveness of adjunctive topical bromfenac, a nonsteroidal antiinflammatory drug, with ranibizumab. METHODS: Patients with wet age-related macular degeneration with lesions smaller than 2 disk diameters were randomized 2:3 to adjunctive topical bromfenac (n = 16) or sham (n = 22) and a 0.5-mg ranibizumab injection in a double-masked fashion. Subjects were examined monthly, and ranibizumab was injected as needed from baseline. The primary endpoint was the comparison of the number of ranibizumab injections over 6 months. The visual and anatomic responses also were compared. RESULTS: The mean number of ranibizumab injections over 6 months was 2.2 in the bromfenac group and 3.2 in the sham, a difference that reached significance (P = 0.0274). The changes in visual acuity did not differ significantly (P = 0.3141) although the central retinal thickness was tended to decrease more in bromfenac group (P = 0.0604). Multivariate analysis showed that topical bromfenac is significantly associated with fewer ranibizumab injections. CONCLUSION: Topical bromfenac might reduce the frequency of ranibizumab over 6 months in eyes with relatively small age-related macular degeneration lesions.

PURPOSE: To evaluate findings in eyes with polypoidal choroidal vasculopathy on indocyanine green angiography (ICGA) and optical coherence tomography (OCT) over 3 months after ranibizumab treatment. METHOD: Fifty-one eyes from 51 patients with treatment-naive polypoidal choroidal vasculopathy received intravitreal ranibizumab injections. We evaluated changes in polypoidal lesions on ICGA and OCT and their correlation over 3 months. Ranibizumab was injected again based on the presence of residual fluid on OCT. RESULTS: Indocyanine green angiography detected 75 polypoidal lesions. All corresponding OCT lesions showed baseline protrusion of the retinal pigment epithelium. At 3 months, 26 lesions (35%) resolved on ICGA: retinal pigment epithelium protrusion on OCT resolved in 10 lesions (38%), 10 lesions (38%) decreased in height, and 6 lesions (24%) remained unchanged. Forty-nine lesions persisted on ICGA, retinal pigment epithelium protrusion resolved in 2 lesions (4%), decreased in 4 lesions (8%), were stable in 36 lesions (73%), and increased in 7 lesions (15%). Three lesions newly developed. Six eyes (12%) had resolved lesions, and 33 eyes (67%) had persistent lesions on ICGA and OCT. Residual exudative changes were associated with persistent lesions on OCT. CONCLUSION: Indocyanine green angiography and OCT baseline findings of polypoidal lesions in polypoidal choroidal vasculopathy were well correlated; however, a discrepancy was seen during treatment. Polypoidal lesions persisted more often on OCT, although ICGA and OCT showed the efficacy of ranibizumab for some polypoidal lesions.

PURPOSE: To report the usefulness of indocyanine green angiography (ICGA) to depict the retinal vascular anomalies associated with distant branch retinal vein occlusion resulting in serous retinal detachment at the macula. METHODS: This was a retrospective, case series of 6 patients (6 eyes) with serous retinal detachments. Fluorescein angiography and ICGA showed that those 6 eyes had a distant branch retinal vein occlusion. The characteristics in ophthalmic examinations such as fundus appearance, fluorescein angiography, ICGA, optical coherence tomography, and clinical courses were evaluated. RESULTS: In addition to serous retinal detachments, five eyes exhibited hard exudates around the macula. Fluorescein angiography and ICGA clearly showed the vessel occlusion; however, no apparent abnormalities appeared in the macular area in any of the eyes. In four eyes, early-phase ICGA depicted the retinal vascular anomalies within the area of venous occlusion and those were seen as hyperfluorescent patches on late-phase ICGA. In two eyes, punctate hyperfluorescent spots were seen in the area of venous occlusion on late-phase ICGA. Optical coherence tomography depicted a serous retinal detachment at the macula and retinal swelling in the outer nuclear layer from the macula to the hyperfluorescent abnormalities on ICGA. The macular serous retinal detachments were resolved within 3 months after laser photocoagulation was applied to the hyperfluorescent areas on ICGA. CONCLUSION: Leakage from subsequent vascular anomalies after branch retinal vein occlusion can cause submacular fluid. Indocyanine green angiography is useful for detecting the causative vascular regions of the fluid.

PURPOSE: To evaluate the progression of early age-related macular degeneration to neovascular age-related macular degeneration (nAMD), and identify the abnormal fundus autofluorescence (FAF) patterns and markers of choroidal neovascularization (CNV) in fellow eyes of patients with unilateral nAMD. METHODS: Sixty-six patients with unilateral nAMD who developed abnormal FAF in the fellow eyes were enrolled in this multicenter, prospective, observational study, and followed-up for 5 years. FAF images on Heidelberg Retina Angiogram Digital Angiography System (HRA) or HRA2 were classified into eight patterns based on the International Fundus Autofluorescence Classification Group system. The patients in which the fellow eyes progressed to advanced nAMD, including those who did not develop nAMD, were assessed based on the following factors: baseline FAF patterns, age, sex, visual acuity, drusen, retinal pigmentation, baseline retinal sensitivity, family history, smoking, supplement intake, hypertension, body mass index, and hematological parameters. RESULTS: Of the 66 patients, 20 dropped out of the study. Of the remaining 46 patients, 14 (30.42%, male: 9, female: 5) progressed to nAMD during the 5-year follow-up. The most common (50% eyes) FAF pattern in the fellow eyes was the patchy pattern. According to the univariate analysis, CNV development was significantly associated with age, supplement intake, and low-density lipoprotein levels (p<0.05). Multivariable analysis revealed that patients who showed non-compliance with the supplement intake were more likely to develop nAMD (p<0.05). No significant association was found between the patchy pattern and CNV development (p = 0.86). CONCLUSION: The fellow eyes (with abnormal FAF) of patients with unilateral nAMD may progress from early to advanced nAMD. However, no FAF pattern was found that predicted progression in nAMD.

BACKGROUND: Although it is known that antioxidants including lutein can affect macular pigment optical density (MPOD) and visual function, we still have much to learn about their effect. Our aim was to assess the 1-year changes in MPOD and visual function in response to supplementation containing lutein. METHODS: We prospectively measured the MPOD level of those who received a supplement containing 6 mg of lutein daily for 1 year. MPOD level was measured every 3 months by using autofluorescence spectrometry with the two-wavelength method. Other examinations, including contrast sensitivity and retinal sensitivity were also measured every 3 or 6 months. Stepwise regression analysis was performed to determine the factors that correlated with the changes observed in those examinations. RESULTS: Forty-three eyes of 43 Japanese subjects, including five normal eyes, five fellow eyes with central serous chorioretinopathy (CSC), and 33 fellow eyes with age-related macular degeneration (AMD) were enrolled. The higher baseline MPOD level was correlated with the eye with a clear intraocular lens (IOL). Although no time-dependent changes in the MPOD level were obtained in any area, subjects without cardiovascular diseases showed higher increase in the MPOD level. We observed significant increases in the contrast sensitivity at 1 year (p = 0.0124) and in the retinal sensitivity at 6 months (p < 0.0001) and 1 year (p < 0.0001). Stepwise regression analysis showed that nonsmokers had increased contrast sensitivity (p = 0.0173), and the fellow eye of those with CSC had less of an increase in retinal sensitivity (p = 0.0491). CONCLUSIONS: Daily supplementation with 6 mg of lutein did not affect the MPOD level for 1 year, suggesting that 6 mg of lutein may be insufficient to increase the MPOD level. However, supplementation seems to improve visual functions such as contrast sensitivity and retinal sensitivity.

PURPOSE: This study aimed to assess driving capabilities in patients with exudative age-related macular degeneration (AMD) causing unilateral blindness or paracentral scotoma without vision deterioration. METHODS: Of the 275 patients with AMD who responded to a questionnaire regarding car driving at Osaka University Hospital, we excluded 78 patients who answered that they had never driven. Finally, 197 patients were included (50 with bilateral and 142 with unilateral AMD). We investigated the relationship between the questionnaire findings and best-corrected visual acuity (BCVA). RESULTS: The mean age was 74.8 ± 6.9 years, and the mean BCVA in the right and left eyes were 0.48 and 0.47, respectively. A negative correlation was observed between the proportion of patients who stopped driving due to AMD and the vision in the worse eye (p < 0.0001); however, 66% of participants were still driving. Regardless of the BCVA, 84% of them wished to continue driving. Concerning perceived dangerous situations, all patients reported an oversight of people or signals and night driving; further, patients with unilateral and bilateral vision deterioration reported vision narrowness and difficulty with discerning signal colours, respectively. CONCLUSION: Despite the associated danger, patients with AMD continued driving. Close attention should be paid to the driving activities among patients with AMD, even if they have passed the relevant driving tests.
RESUMEN
We report a case of unilateral acute idiopathic maculopathy (UAIM) with new clinical findings. A 34-year-old Japanese man had a neurosensory retinal detachment (approximately 5 disk diameters) with yellowish-white exudates at the macula in the left eye (visual acuity (VA) 0.4). Fluorescein angiography (FA) showed early hypofluorescent spots and late pooling in the subretinal space. Three weeks after onset, indocyanine green angiography (IA) showed numerous hypofluorescent spots at the lesion. Optical coherence tomography (OCT) showed subretinal fluids and an elevated choroidal lesion with low reflectivity, suggesting choroidal edema. The VA and fundus appearance spontaneously resolved without treatment three months after onset. The VA was 1.0 six months after onset. Irregular pigmentation remained at the macular lesion. The main UAIM pathology may be outer retinal layer and retinal pigment epithelial inflammation. FA, IA, and OCT suggested that choroidal inflammation may be involved in the pathogenesis of UAIM.

This prospective randomized double-masked study investigated the effects of 20 mg lutein supplementation with two different capsules (beeswax or glycerol fatty acid esters) for 6 months on the fellow eyes of 39 Japanese patients with unilateral age-related macular degeneration, and assessed the factors associated with baseline plasma lutein concentration via lifestyle interviews. Macular pigment optical density (MPOD), determined with the two-wavelength autofluorescence method, increased over time in the beeswax group (ANOVA, p = 0.0451), although the increase from 3 months to 6 months was only marginally significant. No significant increase was observed in the glycerol fatty acid esters group (ANOVA, p = 0.7396). Plasma lutein concentrations significantly increased at 3 and 6 months from baseline in both groups (both p < 0.01). In a multiple regression model, age was negatively associated with higher plasma lutein concentration (p = 0.0305), while consumption of green vegetables was positively associated with baseline plasma lutein concentration (p = 0.0322). In conclusion, a significant increase in MPOD was not fully confirmed with 6 months intake duration despite a significant increase in plasma lutein concentrations. Consumption of green vegetable was confirmed to be associated with plasma lutein concentration after adjusting for other potential factors including age.
