RESUMO

PURPOSE: To describe an atypical case of chronic central serous chorioretinopathy (CSCR) with acute exacerbation consisting of severe exudation at the site of a retinal pigment epithelium (RPE) aperture. METHODS: Case report. RESULTS: A 39-year-old man presented with a recurrence of CSCR in the right eye. Initial evaluation was notable for a RPE aperture overlying a chronic avascular pigment epithelial detachment (PED). He was initially treated with topical dorzolamide and indomethacine. During follow-up, application of topical dermal steroid for a case of athlete's foot led to severe fibrinous exudation originating from the site of the RPE aperture. Half-fluence verteporfin photodynamic therapy (PDT) induced rapid and complete resolution of the retinal findings. CONCLUSION: PDT allowed for excellent resolution of an atypical exudative and fibrinous form of CSCR associated with an RPE aperture.

RESUMO

Background and Objective: Several cases of central serous chorioretinopathy (CSC) in divers have been reported in our medical retina center over the past few years. This study was designed to evaluate possible changes induced by SCUBA diving in ophthalmic parameters and especially subfoveal choroidal thickness (SFCT), since the choroid seems to play a crucial role in physiopathology of CSC. Materials and Methods: Intraocular pressure (IOP), SFCT, pachymetry, flow-mediated dilation (FMD), blood pressure, and heart rate were measured in 15 healthy volunteer divers before diving, 30 and 60 min after a standard deep dive of 25 m depth for 25 min in a dedicated diving pool (NEMO 33). Results: SFCT reduces significantly to 96.63 ± 13.89% of pre-dive values (p = 0.016) 30 min after diving. It recovers after 60 min reaching control values. IOP decreases to 88.05 ± 10.04% of pre-dive value at 30 min, then increases to 91.42 ± 10.35% of its pre-dive value (both p < 0.0001). Pachymetry shows a slight variation, but is significantly increased to 101.63 ± 1.01% (p = 0.0159) of the pre-dive value, and returns to control level after 60 min. FMD pre-dive was 107 ± 6.7% (p < 0.0001), but post-dive showed a diminished increase to 103 ± 6.5% (p = 0.0132). The pre-post difference was significant (p = 0.03). Conclusion: Endothelial dysfunction leading to arterial stiffness after diving may explain the reduced SFCT observed, but SCUBA diving seems to have miscellaneous consequences on eye parameters. Despite this clear influence on SFCT, no clear relationship between CSC and SCUBA diving can be drawn.

RESUMO

PURPOSE: To illustrate with multimodal imaging a case of HELLP syndrome (Hemolysis, Elevated Liver enzymes, Low Platelets) complicated by bilateral multifocal serous retinal detachments, subretinal exudation, and papilledema. METHODS: Case report. Fundus photography, spectral domain optical coherence tomography (SD-OCT), fluorescein angiography, and indocyanine green angiography were performed at presentation and the day after. We also present the SD-OCT follow-up at 8 days, 1 year, and 4 years. RESULTS: A 25-year-old 5-month-pregnant Guinean woman complained about decreased visual acuity in the right eye. Eye fundus and multimodal imaging were abnormal in both eyes. Spectral domain optical coherence tomography showed the presence of multifocal serous retinal detachments, subretinal deposits, and intraretinal cysts. Indocyanin green angiography revealed an irregular choroidal perfusion and localized choroidal ischemia. Spectral domain optical coherence tomography also provided assessment of retinal changes during the long-term follow-up, showing tissue damage in the outer retina. CONCLUSION: Serous retinal detachments during pregnancy can be the leading sign of HELLP syndrome-a potentially life-threatening condition. Spectral domain optical coherence tomography is a noninvasive and useful tool for its diagnosis and follow-up. ICG is important to confirm the choroidal ischemia and choroidal vascular abnormalities, underlying conditions leading to main sign of HELLP syndrome in the eye.

RESUMO

BACKGROUND: The aim of the present study was to describe the prevalence and progression of DR diagnosed by fluorescein angiography (FA) in patients with type 1 diabetes (T1D) during a 30-year follow-up, and the relationship with glycated haemoglobin (HbA1c). MATERIALS AND METHODS: We included 4325 FA reports representing 851 patients with T1D with a mean age at diagnosis of 10.4 years (range: 0.0-49.9) and followed between 1986 and 2015. Clinical characteristics of the population were collected from patients' files. The HbA1c level was measured within a maximum period of ±1 year from the date of FA. Descriptive statistics were realized to study prevalence and progression of DR. RESULTS: At diagnosis of incipient abnormalities, mean age was 22.8 years (range 13.7-46.9) and mean diabetes duration was 13 years (range: 4.3-29.6). Lesions requiring treatment were observed in 5.9% of the patients at a mean age of 32.4 years (range: 30.4-34.3) and a mean diabetes duration of 23.8 years (range: 19.4-28.1). On average, it took 12.9 years (range: 12.2-13.5) to progress from an incipient abnormality to a lesion requiring treatment. Mean HbA1c ± SD was 7.8 ± 1.5% over a period of 30 years. CONCLUSIONS: While it could have been expected to observe a higher prevalence of DR, our study described by far the lowest results of prevalence comparing to similar studies, probably due to a good average HbA1c over 30 years.

RESUMO

PURPOSE: To describe subclinical chorioretinal lesions revealed by indocyanine green angiography (ICGA) and their evolution under systemic treatment in tubulointerstitial nephritis and uveitis (TINU) patients. METHODS: Retrospective case series of three patients with TINU syndrome. Choroidal and retinal involvement were assessed by fluorescein angiography (FA) and ICGA. RESULTS: Three patients were analyzed. FA demonstrated hot disc, associated in two cases with retinal vascular leakage, and ICGA revealed subclinical chorioretinal dots in all three cases. Given the presence of posterior uveitis and deterioration of kidney function, asystemic treatment by oral methylprednisolone was started. Persistence of retinal and choroidal inflammations under systemic corticosteroids required association with immunosuppressive agent to control the disease activity. CONCLUSION: Multimodal imaging and more precisely ICGA is useful to assess subclinical choroidal inflammation and monitor treatment response in TINU syndrome. Immunosuppression needs to be revised and adapted when uveitis and/or kidney function are unresponsive to systemic steroids. ABBREVIATIONS: TINU: tubulointerstitial nephritis and uveitis; TIN: tubulointerstitial nephritis; ACE: angiotensin-converting enzyme; RF: rheumatoid factor; Uß2M: urinary ß-2microglobulin; AMPPE: acute multifocal placoid pigment epitheliopathy; FA: fluorescein angiography; ICGA: indocyanine green angiography; CT: computed tomography.

RESUMO

PURPOSE: To report multimodal imaging findings in two cases of AIDS-related cryptococcal chorioretinitis associated with uveitis and vasculitis. METHODS: Findings on clinical examination, color fundus photography, fluorescein and indocyanine green angiographies, and optical coherence tomography. Patients. Both patients were diagnosed with Cryptococcus neoformans meningitis in the setting of untreated HIV infection with CD4+ T cell count < 100/mm3. Ocular manifestations occurred during the course of the antifungal therapy for meningitis. RESULTS: In both cases, fundus showed vitritis. Fluorescein angiography allowed the characterization of vasculitis lesions, and indocyanine green angiography indicated choroidal involvement. In combination with optical coherence tomography, ICG and FA allowed the assessment of treatment response. CONCLUSION: These two cases reveal the potential of C. neoformans to infect almost all ocular structures and the critical role of multimodal imaging in baseline evaluation and in the follow-up of patients.

RESUMO

PURPOSE: The aim of this study is to report a rare spectral-domain optical coherence tomography finding in the macula. METHODS: This is a descriptive consecutive case series. Patients diagnosed with hyperreflective central perpendicular line in the macular spectral-domain optical coherence tomography were included. Best-corrected visual acuity assessment, standard Amsler grid test, biomicroscopic examination and macular spectral-domain optical coherence tomography were performed. RESULTS: We examined three men and one woman, aged 56 to 91 years (average age: 75.25 years). Spectral-domain optical coherence tomography showed a hyperreflective central perpendicular line in five eyes accompanied by vitreofoveal adhesion in all of them. In two eyes, we observed a lifting of the ellipsoid zone, and in one eye the external limiting membrane was also pulled. In one eye, a subtle lifting of the interdigitation zone was revealed. In another eye, we also found a triangular foveolar detachment of the interdigitation zone. Snellen's best-corrected visual acuity ranged from 0.2 to -0.1 logMAR (average of 0.006 logMAR). Amsler grid test was unremarkable in four eyes and metamorphopsia was detected in one eye. One eye developed a full-thickness macular hole several weeks after the phacoemulsification cataract surgery. CONCLUSION: The presence of a central perpendicular line can be revealed by the macular spectral-domain optical coherence tomography. We hypothesize that this finding could be considered as a sign of vitreomacular traction. In our patients, best-corrected visual acuity was only mildly reduced, and Amsler grid test was affected in only one eye.

RESUMO

PURPOSE: To evaluate the effect of tumor necrosis factor (TNF) inhibitor therapy on ocular relapses in patients with Susac syndrome. METHODS: Multicenter retrospective cohort study of patients diagnosed with Susac syndrome according to classical clinical criteria. We evaluated the disease activity before and after introduction of anti-TNF therapy and its value as a steroid-sparing agent. RESULTS: Five patients were included. All were initially treated with a combination of corticosteroids and classical immunosuppressive drugs. Infliximab was started in three patients, and adalimumab was started in two patients. Patients had on average 5 ocular relapses during a mean follow-up time of 2.59 years before introducing a TNF inhibitor, corresponding with on average 1.93 relapses per year. After the introduction of an anti-TNF agent, this number was reduced by factor 5.51 to an average of 0.35 relapses per year for a mean follow-up of 2.86 years (P = 0.10). Before anti-TNF introduction ocular relapses occurred at a mean daily dose of 34 mg of prednisone, whereas with anti-TNF treatment, corticosteroid administration could be completely stopped in four patients with one patient still needing 5 mg daily (P = 0.10). Infliximab and adalimumab generally were well tolerated, and no serious adverse events were reported. CONCLUSION: Although not statistically significant, our results suggest that anti-TNF therapy can be a valuable option for the treatment of ocular Susac syndrome and may especially be considered in those patients unresponsive to more conventional immunosuppressive treatment.

RESUMO

PURPOSE: To present a case of frosted branch periphlebitis in a young Armenian patient with familial Mediterranean fever. METHODS: Case report. RESULTS: A 37-year-old man presented with a unilateral decreased visual acuity and floaters for 4 days on the left eye (LE). Visual acuity was 20/20 in the right eye (RE) and 20/28 in the LE. Anterior segment and fundus examinations of the RE were normal. Slit-lamp examination of LE revealed a mild nongranulomatous anterior uveitis and vitritis. Intraocular pressure was 19 mmHg in the RE and 12 mmHg in the LE. Fundoscopy of the LE showed typical appearance of frosted branch periphlebitis with perivascular sheathing of the retinal veins and scattered retinal hemorrhages. Fluorescein angiography of the RE was normal. The LE showed optic disk and segmented vascular staining without macular leakage. Optical coherence tomography of the RE was normal; LE demonstrated a localized macular thickening and few intraretinal cysts. The detailed ophthalmologic history was negative. The general history and workup were significant for familial Mediterranean fever and a positive lupus anticoagulant. One week later, the fundus findings worsened with a severe decrease of visual acuity of the LE to 20/200. A single intravitreal (IVT) injection of bevacizumab was performed. Three weeks after injection, fundus findings progressively improved with a decrease of the macular thickening and an improvement of the visual acuity to 20/25. Clinical improvement continued up to the last visit (19 weeks after the injection) with a visual acuity that reached back 20/20 with no signs of active inflammation. CONCLUSION: This case demonstrates a possible association between unilateral frosted branch periphlebitis and familial Mediterranean fever.

RESUMO

OBJECTIVE: Age-related macular degeneration (ARMD) is a leading cause of visual impairment. Intravitreal injections of anti-vascular endothelial growth factor (VEGF) are the standard treatment for wet ARMD. There is however, variability in patient responses, suggesting patient-specific factors influencing drug efficacy. We tested whether single nucleotide polymorphisms (SNPs) in genes encoding VEGF pathway members contribute to therapy response. METHODS AND ANALYSIS: A retrospective cohort of 281 European wet ARMD patients treated with anti-VEGF was genotyped for 138 tagging SNPs in the VEGF pathway. Per patient, we collected best corrected visual acuity at baseline, after three loading injections and at 12 months. We also registered the injection number and changes in retinal morphology after three loading injections (central foveal thickness (CFT), intraretinal cysts and serous neuroepithelium detachment). Changes in CFT after 3 months were our primary outcome measure. Association of SNPs to response was assessed by binomial logistic regression. Replication was attempted by associating visual acuity changes to genotypes in an independent Japanese cohort. RESULTS: Association with treatment response was detected for seven SNPs, including in FLT4 (rs55667289: OR=0.746, 95% CI 0.63 to 0.88, p=0.0005) and KDR (rs7691507: OR=1.056, 95% CI 1.02 to 1.10, p=0.005; and rs2305945: OR=0.963, 95% CI 0.93 to 1.00, p=0.0472). Only association with rs55667289 in FLT4 survived multiple testing correction. This SNP was unavailable for testing in the replication cohort. Of six SNPs tested for replication, one was significant although not after multiple testing correction. CONCLUSION: Identifying genetic variants that define treatment response can help to develop individualised therapeutic approaches for wet ARMD patients and may point towards new targets in non-responders.

RESUMO

PURPOSE: To investigate the effect of a single intravitreal dexamethasone implant (IVT-DI; Ozurdex; Allergan, Inc.) on visual acuity, macular thickness, and intraocular pressure (IOP) in active noninfectious uveitis. METHODS: Medical records of patients with noninfectious active uveitis treated by IVT-DIs were retrospectively reviewed. Uveitis etiologies, treatment indications, best corrected visual acuity (BCVA), central retinal thickness measured by ocular coherence tomography, IOP, and systemic, local, and topical treatments were collected. Parameters were analyzed before the injection of the implant, after 1.5 ± 0.8 months and 4.4 ± 0.9 months for the BCVA, after 2 ± 1.3 months and 4.6 ± 1.3 months for the ocular coherence tomography, and after 1.3 ± 0.7 months and 4.4 ± 1 months for the IOP. RESULTS: We included 14 patients (20 eyes, 20 implant injections) with cystoid macular edema (78%), vasculitis (7%), choroiditis (7%), and vasculitis associated with choroiditis (7%). Before the injection, mean visual acuity was 0.4 ± 0.5 logMAR (logarithm of the minimum angle of resolution) that improved to 0.3 ± 0.5 logMAR (P = 0.0002) after 1.5 ± 0.8 months and to 0.3 ± 0.5 logMAR (P = 0.005) after 4.4 ± 0.9 months. A statistically significant decrease of macular thickness was observed both at 2 ± 1.3 months and at 4.6 ± 1.3 months after IVT-DI. Mean IOP was 16 ± 5 mmHg before injections, 18 ± 6 mmHg (P = 0.13) at 1.3 ± 0.7 months, and 15 ± 4 mmHg (P = 0.65) at 4.4 ± 1 months. By Kaplan-Meier analysis, we found that after 3.3 months, 17% of the eyes still present a BCVA amelioration ≥0.3 logMAR. CONCLUSIONS: In our patients with active noninfectious uveitis, injection of a first single dexamethasone implant was found to improve visual acuity and decrease macular thickness without significant increase of IOP, although the effect seems limited in time.

RESUMO

PURPOSE: To present the case of a young Turkish pregnant patient with bilateral, sight-threatening retinal ischemic vasculopathy and systemic signs suggestive of Behçet disease (oral ulceration, arthritis, and pseudofolliculitis). METHODS: Case report. RESULTS: Multiple areas of superficial, retinal white lesions and few hemorrhages related to occlusions of small retinal vessels were observed at presentation in the macular zone of both eyes. There was gradual improvement of retinal lesions after the administration of corticosteroids and immunosuppressive treatment. CONCLUSION: We report the case of a young pregnant patient with bilateral, sight-threatening retinal ischemic vasculopathy and systemic signs of Behçet disease. Although the systemic signs were highly suggestive of Behçet disease, the ocular presentation was unusual for this multisystemic inflammatory disorder. The differential diagnosis included a number of causes of ischemic retinal vasculopathy, such as systemic vasculitis, antiphospholipid syndrome, Susac syndrome, Purtscher-like retinopathy, and a new variant of acute macular neuroretinopathy (paracentral, acute middle maculopathy), which are further discussed.

RESUMO

BACKGROUND: Susac syndrome is a rare disease attributed to microangiopathy involving the arterioles of the brain, retina, and cochlea. Understanding the pathogenesis is incomplete, but an immune-mediated process remains the leading hypothesis. METHODS: Report of a single case of a previously healthy 22-year-old female patient showing the complete clinical triad. RESULTS: Diagnosis of Susac syndrome in this patient was first questioned due to the atypical initial ophthalmologic presentation with central retinal artery occlusion. Multiple relapses occurred in the fellow eye during follow-up, showing the typical branch retinal artery occlusions, allowing definite diagnosis. CONCLUSION: Susac syndrome should be considered in the differential diagnosis when facing (young) patients with central retinal artery occlusion, especially in the presence of unexplained encephalopathy and/or sensorineural hearing loss.

RESUMO

BACKGROUND: Preretinal haemorrhages usually occur at the interface between the posterior hyaloid and inner limiting membrane (ILM). Less frequently, they are located between the ILM and the retinal nerve fibre layer. Sub-ILM haemorrhages have been described in a variety of clinical settings and often lead to severe visual impairment because of their predilection for the macular region. METHODS: A consecutive series of five cases in which sub-ILM haemorrhages were clinically suspected and confirmed during early vitrectomy with ILM peeling were reviewed. RESULTS: Sub-ILM haemorrhages were clinically suspected in five patients (median age 32 years) based on the fundoscopic appearance and clinical setting of Terson's syndrome (n = 1), Valsalva retinopathy (n = 2), blood dyscrasia (n = 1) and blunt facial trauma (n = 1). Vision was severely impaired in all patients (to hand movements in four of five) because of a premacular location of the haemorrhage. All patients were treated with early pars plana vitrectomy because of insufficient spontaneous visual recovery after a median of 6 weeks. The sub-ILM location of the haemorrhage could be confirmed intraoperatively in all patients by biostaining of the membrane overlying the haemorrhage. ILM peeling and aspiration of the haemorrhage resulted in excellent visual recovery in all patients. No procedure-related complications were observed. CONCLUSIONS: Sub-ILM haemorrhages often occur in a specific clinical context and can lead to severe visual impairment in young patients. Given the excellent results and low complication rates, timely surgical intervention is justified when spontaneous resorption is insufficient.

RESUMO

PURPOSE: To evaluate the efficacy and safety of verteporfin photodynamic therapy (V-PDT) for young adults and children with subfoveal choroidal neovascularization (CNV) associated with toxoplasmic retinochoroiditis. METHODS: Patients with subfoveal CNV associated with toxoplasmic retinochoroiditis were treated with V-PDT and prospectively followed up. Before V-PDT and during follow-up, patients underwent visual acuity testing, complete ophthalmic examination including color photography, angiography with fluorescein and/or indocyanine green, and optical coherence tomography. The decision to retreat CNV was based on the criteria used in the Treatment of Age-Related Macular Degeneration with Photodynamic Therapy investigation. RESULTS: Eight patients (5 males and 3 females) were treated at a mean age of 15.3 years (range, 5-31 years). CNV was 100% classic or predominantly classic in all study patients. Mean visual acuity increased from 20/225 (range, 20/400 to 20/50) to 20/123 (range, 20/200 to 20/25) during a mean follow-up period of 25 months (range, 5-49 months). Persistent closure of CNV was achieved in all eight patients (mean number of treatments, 1.75). Vascular anastomosis developed in the treated area in two patients, but there was no additional visual loss. No significant adverse effects of V-PDT were observed. CONCLUSION: V-PDT for subfoveal CNV associated with toxoplasmic retinochoroiditis appears to be effective and safe even in young adults and children. However, a longer follow-up is recommended to confirm our observations.

RESUMO

PURPOSE: To evaluate the safety and efficacy of photodynamic therapy with verteporfin (PDT) for subfoveal classic choroidal neovascularization (CNV) related to punctate inner choroidopathy (PIC) or presumed ocular histoplasmosis-like syndrome (POHS-like). METHODS: Retrospective review of 16 eyes from 14 patients with subfoveal classic CNV associated with PIC or POHS-like and treated with PDT. RESULTS: The mean visual acuity increased from 4.5/10 (range: 1/10-9/10) to 7/10 (range: 2/10-10/10) after a mean follow-up of 21 months (range: 8-32 months) and a mean number of 2 PDT (range: 1-6). Visual acuity remained stable or improved in 13 of the 16 eyes (81%) and decreased in three. CONCLUSION: This nearly two-year follow-up study suggests that PDT could be helpful for patients with subfoveal classic CNV related to PIC or POHS-like.

RESUMO

PURPOSE: Although photodynamic therapy (PDT) is an established treatment for choroidal neovascularization (CNV), the mechanisms are still not completely elucidated. Damage to the retinal pigment epithelium (RPE) was observed following uncomplicated PDT in young patients. DESIGN: Observational case series. METHODS: Four female patients between the age of 26 and 39 years presented with visual loss because of classic CNV. In two 39 years old females the CNV originated secondary to a small chorioretinal scar, in a 26 and a 36-year-old woman the CNV was of idiopathic cause. All patients received standard PDT according to the Treatment of Age-Related Macular Degeneration with Photodynamic Therapy (TAP) Study protocol. RESULTS: One to three months after an uncomplicated PDT with verteporfin, severe pigment epithelial alterations in the treatment area were observed. The neovascular membranes responded favorably to the treatment and demonstrated fibrosis and resolution of leakage. Ophthalmoscopically and angiographically, atrophy of the retinal pigment epithelium was seen precisely delineating the size of the treatment spot used. Vision declined in two patients from 0.3 to 0.1 and 0.15 to 0.1. The two other patients demonstrated an increase of visual acuity from 0.7 to 0.9 and from 0.4 to 0.9. The retinal pigment epithelium alterations did not resolve during follow-up, but remained unchanged in area and intensity. CONCLUSIONS: Characteristic retinal pigment epithelium alterations were observed in young female patients with small classic CNV following PDT. Unusual retinal pigment epithelium damage in young female patients without any associated disease might be related to a possible inherent defect in the RPE or to the hormonal status of this specific patient population.

RESUMO

PURPOSE: To evaluate the effect of photodynamic therapy on subfoveal neovascular membrane related to type 2A idiopathic juxtafoveolar retinal telangiectasia. DESIGN: Interventional case series. METHODS: Retrospective review of four eyes of four patients who underwent photodynamic therapy for subfoveal neovascular membrane secondary to idiopathic juxtafoveolar retinal telangiectasia. Ocular photodynamic therapy with verteporfin was performed in all cases using standard protocols. Results are given in terms of final visual acuity and neovascular membrane activity based on clinical examination, fluorescein and indocyanin green angiography, and, in two cases, optical coherence tomography. RESULTS: Baseline visual acuity of 20/30 and 20/40 (x2) was maintained in three patients after one, two, and three sessions of photodynamic therapy respectively, and a follow-up of 23, 21, and 9 months. Leakage specific to the subfoveal neovascular membrane ceased on the fluorescein angiography. In the other patient, the final vision decreased from 20/50 to 20/200 after four sessions of photodynamic therapy and a follow-up of 14 months. Although there was still mild persistent leakage on the fluorescein angiography, neovascular membrane size was unchanged, and no subretinal fluid was demonstrated on optical coherence tomography. CONCLUSIONS: Data from this case series suggest that photodynamic therapy may be effective in managing subfoveal neovascular membrane associated with idiopathic juxtafoveolar retinal telangiectasia, which usually carries a poor visual prognosis. Prospective study is required to confirm the beneficial effect of this treatment.
