RESUMO

PURPOSE: To report a case of choroidal neovascularization (CNV) associated with Multiple Evanescent White Dot Syndrome (MEWDS) in a child. STUDY DESIGN: Case report. RESULTS: A 13-year-old child visited us with a month-long history of blurred vision in his right eye. His right fundus showed several subretinal white dots and an atrophic macular lesion corresponding to a CNV. Angiography and optical coherence tomography (OCT) were consistent with the diagnosis of MEWDS. The patient's condition poorly improved after an intravitreal injection of anti-vascular endothelial growth factor (anti VEGF) in his right eye. CONCLUSIONS: We reported the case of CNV associated with MEWDS like reaction. The hypothesis of a triggered-MEWDS was highly suspected but no cause was found, which is often the case in paediatric inflammatory eye disorders. Long-term follow-up is needed to judge the evolution.

RESUMO

PURPOSE: To describe our experience with the use of a sustained-release dexamethasone implant in three patients with recalcitrant macular edema that developed after necrotizing retinitis in the context of the previously treated virus. CASE DESCRIPTION: Two immunocompetent patients presented with unilateral acute retinal necrosis (ARN) due to Varicella-Zoster (VZV). The other, an immunocompromised patient, presented with unilateral cytomegalovirus (CMV) necrotizing retinitis. The diagnoses were confirmed by anterior chamber polymerase chain reaction (PCR) and all were treated with oral valganciclovir and intravitreal ganciclovir (2 mg/0.1 ml). Infection was controlled but two of them required pars plana vitrectomy. Between 2 and 4 months after the resolution of signs of infection, resistant macular edema (RME) developed, and an intravitreal dexamethasone device was implanted after anterior chamber PCR had been negative. Functional and anatomical improvement was achieved, with the resolution of the edema accompanied by improvement in visual acuity in all patients. There was no evidence of reactivation at two years. No cataract or ocular hypertension was observed. One patient required two additional dexamethasone implants. CONCLUSION: Dexamethasone intravitreal implant could be considered as an option for the treatment of macular edema developed after ARN. Care should be taken to avoid reactivation and patients need to be properly informed.

RESUMO

PURPOSE: To report a recurrence of punctate inner choroidopathy (PIC) with an inflammatory choroidal neovascular membrane (iCNVM) after the Pfizer-BioNTech COVID-19 vaccine. METHODS: Case report. RESULTS: A 38-year-old female with a history of myopia and previous episodes of PIC and iCNVM presented with distorted vision in her right eye, seven days after receiving the first dose of the Pfizer-BioNTech COVID-19 vaccine. The patient exhibited active PIC lesions with iCNVM confirmed on multimodal imaging. Treatment with a combination of oral corticosteroids and intravitreal anti-VEGF injection led to disease resolution. Subsequent COVID-19 vaccinations, administered while the patient was immunosuppressed, did not lead to disease relapse. However, relapse occurred following the fourth COVID-19 vaccine, when the patient was not immune suppressed. CONCLUSION: This case highlights the potential risk of PIC disease relapse following COVID-19 vaccination. Further research is needed to investigate the relationship between COVID-19 vaccination and PIC exacerbation, as well as to determine optimal management strategies in this population, including close observation and consideration of prophylactic immune suppression at the time of COVID-19 vaccine for high-risk individuals.

RESUMO

INTRODUCTION: Tuberculosis can involve any organ in the body including ocular tissue of which the uveal tissue is most commonly infected. Choroidal involvement ranges from choroidal tubercles to granulomas. This is one of the few cases of a solitary choroidal granuloma with no other systemic symptoms in an immunocompetent child. METHOD: A case report. RESULTS: A 12-year-old female, presented with diminution of vision in the left eye for a month. The anterior segment of her left eye was normal. A fundus examination revealed an isolated orangish-yellow choroidal mass, 4 DD in size, involving the posterior pole with overlying subretinal exudation. CT scan of the thorax showed large pulmonary, cervical and pancreatic lymph nodes, along with lytic lesions of the thoracic vertebrae. Excision biopsy of the cervical lymph nodes showed caseating granulomas with no e/o malignancies on histopathology. The patient was started on anti-tubercular therapy. Six months after the treatment, the lesion had reduced in size and her vision had improved. CONCLUSION: Isolated choroidal tuberculomas can be present in eyes with little associated ocular inflammation and no other symptoms of systemic tuberculosis. High suspicion, early diagnosis and rapid initiation of medication are important for the treatment of ocular and systemic tuberculosis.

RESUMO

PURPOSE: To evaluate the retinal and choroidal vascular structures in patients with anxiety disorders. METHODS: Thirthy-four eyes of 34 patients who were diagnosed with any anxiety disorders were compared with 32 eyes of 32 age- and sex-matched controls. Central macular thickness (CMT), foveal vascular zone (FAZ) area, total retinal vascular densities of superficial and deep capillary plexus (VDSCP, VDDCP), outer retinal and choriocapillary layers (ORL, CCL) blood flow rates, central subfoveal choroidal thickness (SFCT) and choriodal vascularity index (CVI) were evaluated with optical coherence tomography angiography (OCT-A) and enhanced depth imaging optical coherence tomography (EDI-OCT). RESULTS: No statistical differences were found between the study and control groups in terms of CMT, FAZ area, VDSCP, VDDCP, ORL and CCL blood flow rates. The mean SFCT was 346.26 ± 64.26 µm in patients with anxiety disorder and was found to be statistically significantly thicker than the control group (319.56 ± 37.19 µm) (p = 0.042). Besides, CVI was significantly lower in the study group (71.09 ± 2.64 vs 73.13 ± 3.31, p = 0.008). CONCLUSION: In people with anxiety disorders, the SFCT was found to be thicker and CVI was found to be lower than normal subjects. Although anxiety and stress are important factors in central serous chorioretinopathy, multifactorial factors, including ocular factors, play a role in the pathophysiology of the disease. There is a need for prospective studies with larger series on the subject.

RESUMO

PURPOSE: To report recurrence of tubercular choroiditis following anti-SARS-CoV-2 vaccination in two patients with quiescent disease activity for more than a year. METHODS: Retrospective observational case reports. RESULTS: Two patients (one female and one male) under follow-up for posterior uveitis having stable course with absence of ocular inflammation for more than a year presented with recurrence of choroiditis lesions 2-6 weeks following anti-SARS-CoV-2 vaccination. Both the patients were managed with intravitreal dexamethasone implant (Ozurdex®, Allergan, Inc., Irvine, CA, USA) and showed resolution of choroiditis lesions upon follow-up. CONCLUSIONS: Acute onset recurrence of inflammation, in absence of any change in health status or treatment suggests the potential role of vaccination being the trigger of this reactivation. Given large-scale vaccination against novel coronavirus- SARS-CoV-2, careful vigilance is warranted to pick up the disease recurrence in patients with posterior uveitis.

RESUMO

In this case study, the authors describe peculiar bilateral cotton wool-like retinal lesions associated with macular edema in a patient with COVID-19 who was vaccinated with a single dose of AstraZeneca one month earlier. This patient had no pulmonary or systemic cardiovascular complications from COVID-19, as reported in other papers that found retinal lesions. However, the patient was diagnosed with idiopathic myopathy when discovering the SARS-CoV-2 infection. The patient was a 22-year-old white female with no previous history of morbidity, complaining of blurred vision in both eyes seven days after testing positive for SARS-CoV-2 by PCR (using nasal and oral swab) and confirmed through ELISA blood test (IgM positive). There was no ancillary test revealing diabetes mellitus. The patient presented with scattered whitish cotton wool-like lesions and a few hemorrhages on the posterior pole in fundus examination. On spectral domain optical coherence tomography (SD-OCT), there were hyperreflective lesions in the nerve fiber layer, ganglion cell layer, inner nuclear layer, and inner and outer plexiform layers at the site corresponding to the whitish cotton wool-like lesions in the posterior fundus photos. Moreover, the macula of both eyes had intraretinal and subretinal fluid, reversible with corticosteroid therapy. In conclusion, COVID-19 has been associated with capillary disorders at different target sites such as retina, lungs, and central nervous system. Similarly, vaccination against SARS-CoV-2 has been linked to retinal complications in the literature; however, cotton wool-like lesions have not yet been reported. There are many questions yet to be answered about the implications of COVID-19 infection and its vaccines.

RESUMO

PURPOSE: The purpose of this study is to report our experience with a case of punctate inner choroidopathy (PIC) reactivation following COVID-19. CASE REPORT: A 29-year-old caucasian woman with past ophthalmological history of bilateral PIC reported sudden visual acuity decrease in her right eye (RE) 3 weeks after SARS-CoV-2 infection. Her best-corrected visual acuity (BCVA) was 20/32 in RE; fundus examination and multimodal imaging (including indocyanine-green angiography, fundus autofluorescence, and optical coherence tomography) was consistent with unilateral PIC reactivation. The active choroidal lesions responded to high-dose corticosteroids, with functional improvement. CONCLUSION: Sars-CoV-2 infection could induce autoimmune and autoinflammatory dysregulation in genetically predisposed subjects. We report a case of PIC reactivation following COVID-19.

RESUMO

We report a case of ocular drug toxicity consistent with bilateral Vogt-Koyanagi-Harada (VKH) like disease in a patient with cutaneous melanoma treated with Dabrafenib/Trametinib therapy. A 53-year-old man with a history of metastatic cutaneous melanoma, treated with Dabrafenib/Trametinib, developed a severe acute panuveitis with granulomatous anterior uveitis and multiple serous retinal detachments. The ocular inflammatory reaction was classified as a bilateral Vogt-Koyanagi-Harada disease. Intraocular inflammation resolved after discontinuation of chemotherapeutic agents and aggressive topical and systemic corticosteroid therapy. The present case outlines the importance of recognizing VKH-like syndrome as a possible consequence of therapy with dabrafenib and trametinib.

RESUMO

INTRODUCTION: To report the first case of a serpiginous choroiditis presenting after SARS-CoV-2 infection in a previously healthy young woman. CASE DESCRIPTION: A 41-year-old woman reported blurry vision OS 1 month after a mild SARS-CoV-2 infection. Left eye fundus examination revealed multiple peripapillary atrophic lesions, adjacent to a larger diffuse, ill-defined, yellow-whitish deep amoeboid-like patch, involving the peripapillary region and extending temporally to the fovea. Multimodal imaging including fluorescein angiography, indocyanine-green angiography, fundus autofluorescence and optical coherence tomography was consistent with serpiginous choroiditis. A complete systemic work-up was performed to exclude potential infectious or inflammatory etiologies. The active choroidal lesions responded to high dose corticosteroids, with functional improvement. Immunomodulatory therapy with methotrexate was initiated for long-term management. CONCLUSION: Serpiginous choroiditis is a rare but important sight-threatening condition that has been previously associated to viral infections, which seem to have a role in the induction and/or perpetuation of choroidal inflammation. SARS-CoV-2 infection appears to have played a role as a possible trigger for intraocular inflammation in this case. Therefore, COVID-19 patients reporting visual symptoms should be carefully evaluated in order to obtain adequate ophthalmological management to avoid irreversible visual damage.

RESUMO

PURPOSE: Since its first description by Chang et al. in 1995, the diagnosis of Idiopathic retinal vasculitis, aneurysms and neuroretinitis (IRVAN) syndrome has been based on the findings of Fundus Fluorescein Angiography (FFA). Our purpose was to describe the utility of optical coherence tomography angiography (OCT-A) in its diagnosis and management. CASE DESCRIPTION: A 40-year-old female presented with bilateral blurred vision. Her best corrected visual acuity was at 8/10. Fundus examination revealed blurred disc margins, perivascular exudates, arterial sheaths and retinal hemorrhages bilaterally. FFA showed staining of the optic disc with dye leakage in the right eye, a punctuate hyperfluorescence of the temporosuperior artery in the left eye, bilateral vascular sheathing and capillary dropout. OCT-A showed simultaneous presence of papillary aneurysm and neovascularization of the optic nerve head in the right eye, a papillary aneurysm in the left eye and bilateral capillary non-perfusion. Our patient was diagnosed with IRVAN syndrome. Oral steroids associated with panretinal laser photocoagulation and intravitreal injection of bevacizumab in the right eye resulted in vanishing of the papillary neovascularization with no recurrence on OCT-A at 10-month follow-up. CONCLUSIONS: OCT-A is an additional tool to FFA for visualization of arterial macroaneurysms and retinal neovascularization without the interference of dye leakage. It well demarcates nonperfused areas and ensures follow-up of retinal neovascularization. Its limitations are the limited field of view and the low sensitivity in detecting arteriolar dilations. Thus, OCT-A is unable to outplace FFA but should be considered alternately with it for non-invasive follow-up of IRVAN syndrome.

RESUMO

PURPOSE: To determine the incidence of ocular adverse effects (AEs) following brolucizumab injection for neovascular age-related macular degeneration at a tertiary academic institution. DESIGN: Retrospective, single center cohort study. PARTICIPANTS: All patients who received an intravitreal injection of brolucizumab 6 mg for neovascular age-related macular degeneration between October 7, 2019 and July 31, 2020. METHODS: Medical records of all patients who received brolucizumab 6 mg during the aforementioned time period were carefully reviewed and all ocular adverse effects after injection were charted. MAIN OUTCOME MEASURES: Incidence of post-injection ocular AEs, including intraocular inflammation (IOI), and time to development of AEs after injection. RESULTS: A total of 77 patients received brolucizumab 6 mg for a total of 115 administrations during the study period. There were 4 AEs (3.5%), including three cases of IOI (2.6%), one central retinal artery occlusion, and one retinal detachment. Two men and two women were affected. CONCLUSION: Ocular AEs, including those leading to severe vision loss, may develop after intravitreal brolucizumab 6 mg. A careful discussion of benefits and risks to brolucizumab should be conducted with all patients. PRECIS: In this first case series of ocular adverse effects after brolucizumab 6 mg injection at a single tertiary care center, the incidence of ocular adverse effects was 3.5%, including a 2.6% incidence of intraocular inflammation.

RESUMO

PURPOSE: To assess the ability of wide field Swept Source OCTA (SS-OCTA) imaging to detect morphological variations in Serpiginous Choroiditis (SC) and Serpiginous Like Choroiditis (SLC) in response to treatment and also analyze these findings quantitatively using Image J software. METHODS: Retrospective observational case series of nine eyes with clinical diagnosis of active SC and SLC, who underwent SS-OCTA and fundus autofluorescence (FAF) imaging at baseline and each follow up visit till 6 months. Morphological analysis was done by two independent graders and quantitative analysis to measure the size and intensity of lesion was done using publicly available Image J software at baseline and each follow up visit. DESIGN: Retrospective observational case series. RESULTS: Using SS-OCTA, all the active lesions followed a characteristic healing pattern. Active lesions appear well defined hypo flow void patches and as healing progressed, lesion became more ill-defined and iso-hyper- intense. Significant increase in mean intensity of the lesion could be apparent after 1 and 6 month of treatment. There was reduction in the size of lesions during follow up however this difference was not statistically significant. CONCLUSION: SS-OCTA could be a useful noninvasive tool to study the treatment response in SC/SLC both morphologically as well as quantitatively. Quantitative parameters need to be designed in further research studies to aid in uniform management and follow up of uveitis cases.

RESUMO

An atypical case of acute posterior multifocal placoid pigment epitheliopathy with a clear reappearance of the ellipsoid layer of the retina after Ozurdex® intravitreal implantation is presented. A 51-year-old woman reported a 3-week history of left eye photopsia. On slit-lamp examination, yellowish placoid lesions were found on her left eye fundus. Ancillary tests were performed. The patient was diagnosed as a left eye acute posterior multifocal placoid pigment epitheliopathy, and observational approach was decided. Later, the condition started to progress in an ampiginous manner and a decrease of visual acuity caused by an increase in number and size of the lesions was observed. As the disease was progressing with the conservative, observational approach, and the macula was menaced, an intravitreal dexamethasone implant was injected in the left eye with a consequent improvement of the visual acuity and lesion stabilization. The ellipsoid layer, unidentifiable inside the placoid lesions in previous optical coherence tomography tests, reappeared after the treatment. Intravitreal dexamethasone implants can be used to stabilize acute posterior multifocal placoid pigment epitheliopathy lesions and help resolve the condition. Spectral domain optical coherence tomography can also be useful for monitoring these lesions, as the ellipsoid layer may reappear upon resolution.

RESUMO

PURPOSE: To evaluate the choroidal vascularity index of eyes for acute and chronic central serous chorioretinopathy patients using swept-source optical coherence tomography generated en-face scans. METHODS: This was a retrospective study, in which slabs of en-face optical coherence tomography scans, at 5 µm intervals, spanning from the retina to choroid, were binarized using a validated algorithm to calculate choroidal vascularity index. The choroidal vascularity index was defined as the ratio between the choroidal vascular luminal area and the total choroidal area. Choroidal vascularity index was calculated for all the slabs of every subject in both the groups. RESULTS: A total of 30 eyes for each acute and chronic central serous chorioretinopathy groups were recruited. The mean choroidal vascularity index of the acute group was 45.21% ± 2.25% at the choriocapillaris, which increased to the maximal value of 48.35% ± 2.06% at 75% depth of the choroidal thickness and 45.31% ± 3.27% at the choroidoscleral interface; whereas for the chronic group, the mean choroidal vascularity index was 44.76% ± 2.60% at the choriocapillaris, which maximized at 50% choroidal depth (48.70% ± 1.32%) and then returned to 45.41% ± 6.02% at the choroidoscleral interface. CONCLUSION: For both groups, the choroidal vascularity index increased from choriocapillaris to maximum values at mid-choroid and returned to almost the choriocapillaris value at the choroidoscleral interface.

RESUMO

PURPOSE: To describe clinical findings through ultra-wide field (UWF) images and optical coherence tomography angiography (OCT-A), in Susac's syndrome (SS). METHODS: SS patients were retrospectively analyzed in a single center. Clinical features, ultra-wide-field retinographies (UWF-PR), UWF fluorescein angiographies (UWF-FA), and optical coherence tomography angiography & en face (OCT-A/EF) were reviewed. RESULTS: Twelve eyes from six patients with a mean follow-up of 35.66 months ± SD 36.88 were included. UWF-PR showed areas of retinal whitening and cotton-wool spots in all the eyes after acute attack. Segmentary mid peripheral arteriolitis could be observed in five eyes by UWF-FA in acute and convalescent stages. OCT-A revealed capillary density changes in all of the affected eyes. During the acute phase there was a well-preserved superficial capillary network, while deep retinal plexus showed a lower density in the affected areas. OCT-A/EF revealed deep retinal plexus drop-out and surrounding edematous retina in acute attacks, becoming atrophic over time. Conversely, superficial plexus was much less affected. Perifoveal reperfusion was seen in seven eyes after the acute attack. CONCLUSIONS: UWF-PR/FA and OCT-A/EF might be helpful to stablish an early diagnosis and to monitor SS progression.

RESUMO

PURPOSE: To introduce a new color imaging technique using improved settings of red, green, and blue channels for improved delineation of retinal damage in patients with solar retinopathy. METHOD: A retrospective case series of patients with poor vision secondary to solar retinopathy were analyzed. All patients underwent visual acuity, refraction, and dilated fundus examination. A spectral domain-optical coherence tomography of the macula and color fundus imaging using optimized red, green, and blue color setting was performed. Patients were reviewed over a 6-month period. The data were analyzed for statistical significance using an independent t test and a receiver operating characteristic curve. RESULTS: In total, 20 eyes of 10 patients were included between 2009 and 2017. The mean age was 24.9 ± 18.1 years. Best corrected visual acuity at first consultation was 0.78 ± 0.11 and after 6 months was 0.83 ± 0.09. Spectral domain-optical coherence tomography demonstrated retinal abnormalities at the myoid zone, ellipsoid zone, and the outer segment of photoreceptors. Receiver operating characteristic curve analysis showed an improving effect (area under the curve = 0.62; 95% confidence interval = 0.42-0.79). The color channels parameters, which improve visualization of the lesions were found to be 67-0.98-255 for the R-guided setting, 19-0.63-121 for the B-guided setting, and 7-1.00-129 for the G-guided setting. The ideal red, green, and blue setting was in 24-0.82-229. CONCLUSION: The use of a new setting of red, green, and blue channels could improve the diagnosis and monitoring of solar retinopathy, hence improving patient care.

RESUMO

PURPOSE: To investigate the effects of topical nepafenac on choroidal thickness (CT) following uneventful phacoemulsification surgery (UPS) using enhanced depth imaging optical coherence tomography (EDI-OCT). METHODS: This prospective study included 45 randomly selected eyes (23 eyes of 23 patients used nepafenac (nepafenac group) and 22 eyes of 22 control patients did not use nepafenac (nepafenac-free group)) undergoing small-incision UPS. All participants underwent full ophthalmologic examination. CT measurements were performed at subfoveal, 1.0 mm temporal, and 1.0 mm nasal using the EDI-OCT preoperatively, 1 day, 1 week, and 1 month postoperatively. RESULTS: The mean subfoveal, nasal, and temporal CT in the nepafenac-free group had changed from 268.95 ± 63.59 µm to 283.36 ± 65.63 µm, 237.22 ± 64.09 µm to 253.09 ± 67.27 µm, and 235.95 ± 75.22 µm to 259.09 ± 63.66 µm preoperatively to 1 month postoperatively, respectively (p < 0.001, p < 0.001, p < 0.001, respectively). The mean subfoveal, nasal, and temporal CT in the nepafenac group had changed from 259.65 ± 55.99 µm to 276.65 ± 59.21 µm, 236.34 ± 55.40 µm to 251.00 ± 62.39 µm, and 247.56 ± 50.88 µm to 261.13 ± 53.73 µm preoperatively to 1 month postoperatively, respectively (p < 0.001, p < 0.001, p < 0.001, respectively). The postoperative CT continued to increase significantly during the follow-up period in two groups. However, compared to the change from baseline to month 1, there was not a statistically significant difference between the groups at subfoveal, nasal, and temporal CT (p: 0.633, p: 0.865, and p: 0.328, respectively). CONCLUSION: UPS may cause a significant increase in CT. Although increasing in the CT was lower in the nepafenac group than the nepafenac-free group, there was not a statistically significant difference between the groups.

RESUMO

BACKGROUND: Garcinia cambogia contains hydroxycitric acid. Hydroxycitric acid is a potent competitive inhibitor of adenosine triphosphate citrate lyase which is a key enzyme in the synthesis of fatty acids. Hydroxycitric acid also regulates the level of serotonin. In these regards, hydroxycitric acid has been reported to exhibit weight loss activity. Adverse reactions of G. cambogia from numerous clinical studies demonstrated relatively mild reactions. However, there are some complications of G. cambogia reported in the past: acute liver injury, acute hepatitis, and hepatic failure. However, ocular complications of G. cambogia have not been reported yet. CASE PRESENTATION: A 35-year-old female visited our clinic with decreased vision in the left eye and ocular pain in both eyes for the last 6 days. She also complained of headache, dizziness, and nausea. She had taken G. cambogia extract more than the recommended dose. There was myopic shift with anterior chamber shallowing in both eyes, especially in the left eye. Moreover, swelling and retinal folds of peripapillary retinal nerve fiber layer and macula were observed in both eyes. These ocular complications of G. cambogia extract resolved after discontinuation of the extract and topical and oral steroid treatment. Herein, we report the first case of ocular complications of G. cambogia extract diet pill assessed with optical coherence tomography of optic disk and macula along with dual Scheimpflug analyzer. CONCLUSION: It is necessary that physicians dealing with obesity advice patients about possible visual disturbance of this extract when taken in overdose so that they can see an ophthalmologist immediately.
