Quantitative and comparative analysis of thermography parameters in posterior scleritis, choroiditis, and controls.

PURPOSE: To compare various ocular thermography parameters in posterior scleritis (PS), choroiditis (choroidal granuloma [CG], Vogt-Koyanagi-Harada [VKH] syndrome), central serous chorioretinopathy (CSCR), and healthy controls. METHODS: This retrospective, observational, comparative study evaluated cases undergoing ocular thermography between April 2017 and October 2023. The study groups included cases of PS, CG, and VKH, while the control group comprised CSCR cases and healthy individuals. Various thermography parameters were assessed, which were as follows: Ocular surface temperature (OST), central corneal temperature (CCT), average scleral temperature (ST), nasal scleral temperature (nST), temperature difference between both the eyes (∆t), and difference between scleral and corneal temperatures (ST - CCT, nST - CCT). RESULTS: It was found that ∆t was significantly higher in the PS group compared to the CG ( P = 0.005), CSCR ( P = 0.0001), and control groups (dilated control: P =0.006, undilated control: P = 0.0001). ST - CCT and nST - CCT were significantly higher in the undilated control and CSCR groups and significantly lower in the PS group. ST - CCT and nST - CCT showed less difference in the affected eyes compared to contralateral healthy eyes of PS and CG cases. OST, CCT, ST, and nST displayed statistically insignificant differences across all groups. CONCLUSION: It is advisable to focus on temperature differences between the affected and healthy eyes, or the difference between the central corneal and scleral temperature of the affected eye, utilizing parameters such as ∆t, ST - CCT, and nST - CCT. These composite parameters offer a more effective approach than individual measurements like OST, CCT, ST, and nST. Thermography can serve as a screening tool to suspect and differentiate PS.

Immunomodulatory Treatment Versus Systemic Steroids in Inflammatory Choroidal Neovascularization Secondary to Idiopathic Multifocal Choroiditis.

PURPOSE: To evaluate the influence of immunomodulatory therapy (IMT) on visual and treatment outcomes of inflammatory choroidal neovascularization (iCNV) in patients affected by multifocal choroiditis (MFC), and to compare them to patients treated with steroids as needed. DESIGN: Multicenter retrospective matched cohort study. METHODS: Patients affected by MFC with iCNV were divided into a IMT group and a "steroids as needed" group and matched according to the time between diagnosis and beginning of systemic treatment. Visual acuity (VA), number of anti-vascular endothelial growth factor (VEGF) intravitreal injections, and number of iCNV reactivations during 2 years of follow-up after treatment initiation were compared between the 2 groups. RESULTS: A total of 66 eyes of 58 patients were included, equally divided into the 2 groups. Patients in the IMT group had a lower relative risk (RR) of iCNV reactivation (0.64, P = .04) and of anti-VEGF intravitreal injection retreatment (0.59, P = .02). Relapses of MFC-related inflammation were independently associated with a higher RRs of iCNV reactivation (1.22, P = .003). Final VA was higher in the IMT compared to the steroids as needed group (mean [SD], 69.1 [15.1] vs 77.1 [8.9] letters, P = .01), and IMT was associated with greater VA gains over time (+2.5 letters per year, P = .04). CONCLUSIONS: IMT was associated with better visual and treatment outcomes in MFC complicated by iCNV compared to steroids as needed. The better outcomes of the IMT group and the association between MFC-related inflammation and iCNV reactivations highlight the need for tighter control of inflammation to prevent iCNV relapses and visual loss.

Semi-automated quantitative analysis of the middle limiting membrane in tubercular serpiginous-like choroiditis using swept-source optical coherence tomography.

To analyze the longitudinal changes in the outer plexiform layer (OPL) in patients with tubercular serpiginous-like choroiditis (TB SLC) and compare it to the healthy control population. Clinical and imaging data of subjects with TB SLC (minimum 6-month follow-up) and healthy control subjects were reviewed. Optical coherence tomography (OCT) imaging obtained using swept-source device (DRI Triton, Topcon, Japan) from three visits (baseline, 3 months, and 6 months) were analyzed. Three OCT scans were chosen-one passing through the center of the fovea, one line above, and one line below. After random indexing to anonymize the images, they were pre-processed and fed into an automated pipeline to identify, crop, and measure the area of the OPL in the line scan. Longitudinal comparisons of OPL within the patient group were performed. The study included 32 eyes (16 patients; 11 males; mean age: 32.9 ± 7.8 years) with TB SLC. Twenty-eight eyes (14 subjects; 10 males: mean age: 31.1 ± 6.2 years) of healthy control subjects (age- and gender-matched) were also selected. The area of OPL was significantly different between the baseline and month 6 visit (6288 ± 1803 versus 5487 ± 1461; p = 0.0002) at the central scan passing through the fovea. For the scans above and below the fovea, the reduction in OPL area was significant at each visit (p < 0.0001). In comparison with healthy control subjects, OPL area values in patients with TB SLC were significantly lower at the month-3 (6116 ± 1441 versus 7136 ± 2539; p = 0.04) and the 6-month visit (5487 ± 1461 versus 7136 ± 2539; p < 0.001). The atrophied OPL at month 6 has been referred to as the "middle limiting membrane" (MLM). Subjects with TB SLC may develop progressive atrophy of the OPL resulting in formation of MLM, which is seen as a hyper-reflective line replacing the OPL. The analysis of longitudinal changes in the OPL may be useful in predicting anatomical and functional outcomes in these patients.

Punctate inner choroidopathy with atypical presentation / Coroidopatia interna ponteada de apresentação atípica

ABSTRACT We report a case of a young Caucasian female presenting with sudden decrease of vision in the left eye, metamorphopsia, and nasal scotoma. Past medical history revealed a diagnosis of myasthenia gravis, which was currently treated with azathioprine, pyridostigmine, and prednisone. Ophthalmological examination showed fundus with clear vitreous and yellow-white lesions that were isolated and perimacular in the right eye, multiple and confluent in the macula, and punctate in periphery in the left eye. Laboratory workup ruled out the presence of infectious and inflammatory diseases. Fundus autofluorescence disclosed hypoautoflurescence with hyperfluorescent margins corresponding to the lesions observed in both eyes and the angiogram revealed hyperfluorescence since early phases without late leakage. Spectral-domain optical coherence tomography showed areas of intermittent retinal pigment epithelium elevations and disruption of the ellipsoid zone. She was diagnosed with punctate inner choroidopathy and then treated with an increased dose of daily prednisone, which resulted in progressive improvement of her visual acuity and anatomical status.(AU)

RESUMO Relato de caso de mulher jovem, caucasiana, com súbita diminuição de acuidade visual de olho esquerdo, metamorfopsia e escotoma nasal. Apresentava diagnóstico de Miastenia gravis, em tratamento com Azatioprina, Piridostigmina e Prednisona. Fundo de olho demonstrava vítreo límpido e lesões amarelo-esbranquiçadas, perimaculares e isoladas em olho direito, múltiplas e confluentes em mácula e pontilhadas em periferia no olho esquerdo. Exames laboratoriais descartaram doenças infecciosas e inflamatórias. Auto-fluorescência revelou lesões hipoautofluorescentes com margens hiperfluorescentes correspondentes às observadas em ambos os olhos, enquanto angiofluoresceinografia mostrou hiperfluorescência desde as fases iniciais sem vazamento tardio. Tomografia de coerência óptica de domínio espectral revelou áreas de elevações intermitentes do epitélio pigmentar da retina e interrupção da zona elipsóide correspondente. Definiu-se como diagnóstico a coroidopatia interna ponteada, sendo instituído aumento na dose diária de Prednisona, com melhoria progressiva da acuidade visual e do aspecto de fundo de olho da paciente.(AU)

LONGITUDINAL FOLLOW-UP OF TUBERCULAR SERPIGINOUS-LIKE CHOROIDITIS USING OPTICAL COHERENCE TOMOGRAPHY ANGIOGRAPHY.

PURPOSE: To analyze and describe serial follow-up of choriocapillaris alterations in tubercular serpiginouslike choroiditis (SLC) using optical coherence tomography angiography (OCTA) and to compare it with multimodal imaging. METHODS: In this prospective cohort study, patients with active tubercular SLC underwent OCTA using Optovue RTVue XR Avanti and other imaging techniques including enhanced-depth imaging OCT (EDI-OCT) (Heidelberg Spectralis; Heidelberg Engineering, Heidelberg, Germany), fundus autofluorescence, fluorescein angiography, and indocyanine green angiography. Serial imaging was performed for a total follow-up of 3 months. Choriocapillaris alterations at the site of lesions were analyzed on OCTA imaging, and their mean lesion areas were calculated. RESULTS: Twenty-six eyes (26 patients; 20 males; mean age: 32.68 ± 10.56 years) were included. Fourteen eyes had active multifocal lesions (n = 39), whereas 12 eyes had active placoid lesions (n = 12). At baseline, OCTA showed hyporeflective flow deficit lesions corresponding to the hypofluorescent lesions on indocyanine green angiography in all eyes. In the multifocal type of SLC, the mean lesion area decreased in all eyes compared with baseline, and lesions with a lesion area less than 0.1 mm2 on OCTA showed near-complete resolution with minimal choriocapillaris atrophy. In comparison, all eyes with a placoid type of SLC showed no significant reduction in the lesion area and showed extensive choriocapillaris atrophy. CONCLUSION: Optical coherence tomography angiography has the unique ability to demonstrate pathological flow impairment at the level of choriocapillaris in active tubercular SLC. Serial OCTA analysis reveals that large tubercular SLC lesions result in choriocapillaris atrophy as the lesions heal, whereas smaller multifocal lesions show resolution of choriocapillaris hypoperfusion with minimal atrophy.

Systemic Immunosuppression Is Highly Effective in the Long-term Control of Inflammatory non-infectious Uveitic Choroidal Neovascularization: A Comparative Study.

Purpose: To compare immediate versus delayed introduction of immunosuppressives for naive noninfectious inflammatory choroidal neovascularization (iCNV).Methods: a retrospective, consecutive, comparative, interventional case series of patients with a diagnosis of inflammatory CNV and a minimum follow of 36 months. Patients were divided into two groups: Group A received Immunosuppressives if needed, while Group B since baseline. Both groups received systemic steroids and intravitreal ranibizumab since baseline. Primary end point was to compare the BCVA outcome till 36-month follow-up.Results: Twenty-nine eyes with iCNV were enrolled. In the long term, best-corrected visual acuity (BCVA) was significantly better in group B. At 3-month follow-up, Group B reduced steroids <10 mg/day significantly (p = .0001, Fisher's Exact Test). At 36 months of follow up, injections given were 2.9 (0.9 SD) in group A and 1.25 (0.4 SD) in group B.Conclusion: early immunosuppressive therapy exerts a positive action on the long-term control of uveitic CNV.

The Use of Optical Coherence Tomography Angiography in the Diagnosis of Inflammatory Type 1 Choroidal Neovascularization Secondary to Tuberculosis: A Case Report.

Purpose: To report a case of choroidal neovascularization (CNV), which was not obvious with dye angiography but was detected with optical coherence tomography angiography (OCTA).Methods: A 50-year-old female presented with decreased vision in her right eye. Funduscopic examination revealed a swollen hyperemic disc, peripapillary exudation, and choroidal infiltration.Results: Optical coherence tomography revealed intraretinal cysts, subretinal fluid in the macular region, and subretinal hyperreflective material in the papillomacular area. Fluorescein angiography revealed early hypofluorescence in the areas of choroidal infiltrations, and indocyanine green angiography (ICGA) also showed hypocyanescence corresponding to these infiltrations and revealed a faint hypocyanescence in the papillomacular region, further corresponding to the subretinal hyperreflective material on OCT scan. Two weeks after the initiation of systemic therapy with the diagnosis of tuberculosis, OCTA scans detected Type 1 CNV in the peripapillary area.Conclusion: OCTA may be superior to ICGA in the detection of CNV secondary to inflammatory situations.

Manejo da coroidite interna punctata complicada por membrana neovascular sub-retiniana / Management of punctate inner choroidopathy complicated by subretinal neovascular membrane

RESUMO Este trabalho visou evidenciar a importância da detecção precoce da coroidite interna punctata e destacar sua fisiopatologia inflamatória e possíveis diagnósticos diferenciais dentro das white dot syndromes. O destaque foi dado principalmente à coroidite multifocal e à panuveíte, ao se demonstrar sua epidemiologia peculiar em mulheres jovens, caracterizar sua apresentação clínica típica na fundoscopia e explorar as vantagens e as desvantagens de realizar os exames complementares que fazem parte da análise multimodal útil para o diagnóstico (especialmente a angiografia fluoresceínica, a tomografia de coerência óptica e a indocianina verde). Descreve-se o caso de uma mulher de 28 anos diagnosticada com coroidite interna punctata com membrana neovascular coroidal em olho direito. O tratamento foi realizado com injeção intravítrea de aflibercepte e corticoterapia sistêmica 1mg/kg ao dia. Este relato é importante por permitir debater o manejo da coroidite interna punctata durante a gestação e a decisão de realizar o tratamento mediante uma diversidade de opções terapêuticas.

ABSTRACT This work aimed to demonstrate the importance of early detection of punctate inner choroidopathy, highlighting the pathophysiology of inflammation and the differential diagnoses among white dot syndromes. Special attention was given to multifocal choroiditis and panuveitis, by demonstrating the peculiar epidemiology in young women, characterizing the typical clinical presentation in ophthalmoscopy, and exploring the advantages and disadvantages of performing the complementary examinations, which are part of the multimodal analysis useful for diagnosis (particularly fluorescein angiography, optical coherence tomography, and indocyanine green). We report the case of a 28-year-old female, diagnosed as punctate inner choroidopathy with choroidal [N.T. no título aparece subretinal = subrretiniana] neovascular membrane in the right eye. She was treated with intravitreal injection of aflibercept and systemic corticosteroid 1 mg/kg/day. This case report is important for addressing the management of punctate inner choroidopathy during pregnancy, and the decision to carry out treatment considering diverse therapeutic options.

Persistent Placoid Maculopathy: Prognosis Factors and Functional Outcomes.

Purpose: To identify prognosis factors and functional outcomes of persistent placoid maculopathy (PPM). Methods: We collected personal PPM cases and combined them with the data from the literature. Results: 68 eyes of 37 patients with PPM were analyzed, including six new cases. Twenty-six patients were men (70%) with a mean age of 51.8 years old. The mean initial visual acuity (VA) was 0.52 LogMar ± 0.55 for a mean final VA of 0.49 LogMar ± 0.51. Risk factors for poor VA included: initial VA less than 0.2 LogMar (p < .0001), cardiovascular risk factor (p = .008), autoimmune-related and/or systemic pro-inflammatory conditions (p = .003), choroidal neovascularization (p = .001), macular atrophy (p = .03) and absence of systemic corticosteroid treatment (p = .03). Conclusion: PPM is a choroidal inflammation. Identifying prognosis factors may help to guide treatment and follow-up. We showed that anti-inflammatory drugs, and anti-VEGF injections in cases of choroidal neovascularization, may lead to better outcomes.

Treatment of Serpiginous Choroiditis with Chlorambucil: A Report of 17 Patients.

PURPOSE: To evaluate the efficacy of chlorambucil in the treatment of serpiginous choroiditis. METHODS: Patient records from the Massachusetts Eye Research and Surgery Institution (MERSI) were reviewed from over the past 10 years. In total, 17 patients with the diagnosis of serpiginous choroiditis treated with chlorambucil were identified. QuantiFERON gold was negative in all of them. Chlorambucil was started at 0.15 mg/kg and dosage was titrated up using weekly white blood cell (WBC) count to achieve a target cell number of 3.0-4.5 × 109 cells/L. The goal of therapy was to maintain this value for at least 6-9 months. Adverse effects, recurrence, rate of new choroidal neovascularization (CNVM), and visual acuity before and after treatment were recorded. RESULTS: The mean age of the 17 patients with the diagnosis of serpiginous choroiditis treated with chlorambucil was 46 years, and six patients (35%) were male. The mean duration of treatment for chlorambucil was 8.4 months. None of them developed cancer or persistent side-effects, with a mean follow-up of 53 months. Of the patients, 12 (71%) achieved an average of 45 (5-120) months drug-free remission in their last follow-up. Visual acuity of 33 treated eyes remained within two lines of Snellen acuity in 27 eyes (82%), improved in one eye (3%), and deteriorated in five eyes (15%). Leukopenia was the most common side-effect, which was reversible in all cases. CONCLUSIONS: Chlorambucil in a relatively short duration of time, with an escalating dose guided by weekly WBC was well tolerated, as well as effective in preventing recurrence and maintaining vision in patients with serpiginous choroiditis.

Short-term Intensive Immunosuppression: A Randomized, Three-arm Study of Intravenous Pulse Methylprednisolone and Cyclophosphamide in Macular Serpiginous Choroiditis.

PURPOSE: To compare the efficacy of pulse cyclophosphamide with pulse dexamethasone in acute macular serpiginous choroiditis (SC). METHODS: A total of 30 patients with macular SC were prospectively randomized into three treatment groups: group D (pulse dexamethasone); group C (pulse cyclophosphamide); and combination (pulse group DCP) administered for 3 days. Macular SC was defined as any active lesion involving/threatening macula. RESULTS: A total of 30 patients were enrolled, with 10 patients in each group. Lesions completely healed at median duration of 2 weeks in each group, with significant improvement in visual acuity compared with pretreatment levels (p<0.05). Pulse cyclophosphamide was most effective in faster healing of lesions compared with other groups. There was no difference in gain in visual acuity between any of the groups (p = 0.32). CONCLUSIONS: Cyclophosphamide may be an effective treatment modality for acute macular SC, though it may not have a long-term effect on disease relapse.

Swept-source optical coherence tomography angiography in serpiginous choroiditis.

BACKGROUND/AIMS: To analyse choroidal vascular density of affected and non-affected areas in active and inactive serpiginouschoroiditis (SC) by means of optical coherence tomography angiography (OCT-A). METHODS: In this cross-sectional and observational study, 22 eyes of 11 patients diagnosed with SC were included. All patients underwent blue-light fundus autofluorescence (spectralis Heidelberg retinalangiography+OCT) and swept-source OCT-A (AngioPlex Elite 9000 SS-OCT, Carl Zeiss Meditech) to analyse qualitative features and choroidal vessel density of areas considered affected, and the inner and the outer border of the lesions. Unaffected areas of otherwise healthy retina have also been studied. RESULTS: All inactive inflammatory lesions were characterised by atrophy of choriocapillaris with an impairment of its detectable flow and greater visibility of choroidal vessels. On the other hand, all active inflammatory lesions showed an area of complete absence of decorrelation signal. The pathological border was characterised by a statistically significant lower choroidal vessel density compared with both the outer border and the unaffected area (0.650±0.113 vs 0.698±0.112, (p<0.001)). Although not statistically significant, vessel density of the outer border of inactive lesions was lower than vessel density of unaffected areas (0.650±0.113 vs 0.698±0.112, p=0.441). Active inflammatory lesions showed an area of complete absence of decorrelation signal at the level of the choriocapillaris and whole choroid. CONCLUSION: OCT-A represents a new imaging technique that provides useful information about the leading changes of choroidal vascular network in active and inactive lesions of SC.

Blau Syndrome-Associated Uveitis: Preliminary Results From an International Prospective Interventional Case Series.

PURPOSE: Provide baseline and preliminary follow-up results in a 5-year longitudinal study of Blau syndrome. DESIGN: Multicenter, prospective interventional case series. METHODS: Baseline data from 50 patients from 25 centers worldwide, and follow-up data for patients followed 1, 2, or 3 years at the end of study enrollment. Ophthalmic data were collected at baseline and yearly visits by means of a standardized collection form. RESULTS: Median age at onset of eye disease was 60 months and duration of eye disease at baseline 145 months. At baseline 38 patients (78%) had uveitis, which was bilateral in 37 (97%). Eight patients (21%) had moderate to severe visual impairment. Panuveitis was found in 38 eyes (51%), with characteristic multifocal choroidal infiltrates in 29 eyes (39%). Optic disc pallor in 9 eyes (12%) and peripapillary nodules in 9 eyes (12%) were the commonest signs of optic nerve involvement. Active anterior chamber inflammation was noted in 30 eyes (40%) at baseline and in 16 (34%), 17 (57%), and 11 (61%) eyes at 1, 2, and 3 years, respectively. Panuveitis was associated with longer disease duration. At baseline, 56 eyes (75%) were on topical corticosteroids. Twenty-six patients (68%) received a combination of systemic corticosteroids and immunomodulatory therapy. CONCLUSIONS: Blau uveitis is characterized by progressive panuveitis with multifocal choroiditis, resulting in severe ocular morbidity despite continuous systemic and local immunomodulatory therapy. The frequency and severity of Blau uveitis highlight the need for close ophthalmologic surveillance as well as a search for more effective therapies.

Application of OCT-angiography to characterise the evolution of chorioretinal lesions in acute posterior multifocal placoid pigment epitheliopathy.

PurposeThe aim of this study was to determine a sequence of structural changes in acute posterior multifocal placoid pigment epitheliopathy (APMPPE) using optical coherence tomography-angiography (OCT-A) and comparing with other imaging modalities.Patients and methodsPatients with a new diagnosis of acute-onset APMPPE referred to a regional specialist centre from October 2015 to October 2016 were included. Multimodal imaging employed on all patients from diagnosis included the following: fundus fluorescein angiography, indocyanine green angiography, fundus autofluorescence, spectral domain-OCT (SD-OCT), and OCT-A. All non-invasive imaging processes were repeated during follow-up.ResultsTen eyes of five patients were included in the study, three males and two females, with a mean age of 26.2 years (range: 21-32) and a mean follow-up of 6.4 months (range: 2.6-13.3). All patients presented with bilateral disease and macular involving lesions. OCT-A imaging of the choriocapillaris was supportive of hypoperfusion at the site of APMPPE lesions during the acute phase of this condition with normalisation of choroidal vasculature during follow-up. Multimodal imaging consistently highlighted four sequential phases from presentation to resolution of active disease.ConclusionsMultimodal imaging in patients with APMPPE in acute and long-term follow-up demonstrates a reversible choroidal hypoperfusion supporting the primary inciting pathology as a choriocapillaritis. The evolution shows resolution of the ischaemia through a defined sequence that results in persistent changes at the level of the retinal pigment epithelium and outer retina. OCT-A was able to detect preclinical changes and chart resolution at the level of the choriocapillaris.

Multimodal Imaging Including Optical Coherence Tomography Angiography in Serpiginous Choroiditis.

PURPOSE: To report multimodal imaging in patients with serpiginous choroiditis. METHODS: A 60-year-old woman with active serpiginous choroiditis in the right eye was evaluated during the disease course with multimodal imaging, which included fluorescein angiography, swept-source optical coherence tomography (SS-OCT), OCT angiography, fundus autofluorescence (FAF), and retromode imaging. RESULTS: The patient had subretinal, yellowish lesion on the macula at presentation. The margin of the lesion was remarkable in FAF and retromode imaging. SS-OCT scans revealed slightly thickened hyporeflective space and tiny hyperreflective spots at the choriocapillaris level. OCT angiography demonstrated decreased vascularity on the choriocapillaris. Although the area was partially replaced with irregular capillaris, the photoreceptor defect persisted following systemic corticosteroid therapy. CONCLUSIONS: Multimodal imaging shows that inflammation of the choriocapillaris is a main pathology of serpiginous choroiditis. The destruction of the choriocapillaris may lead to the photoreceptor disruption, resulting in permanent visual loss in serpiginous choroiditis.

ACUTE POSTERIOR MULTIFOCAL PLACOID PIGMENT EPITHELIOPATHY ON OPTICAL COHERENCE TOMOGRAPHY ANGIOGRAPHY.

PURPOSE: To investigate choroidal involvement in acute posterior multifocal placoid pigment epitheliopathy (APMPPE). METHODS: A retrospective observational case series using multimodal imaging including optical coherence tomography (OCT) angiography. RESULTS: Five patients with APMPPE were included. In most acute lesions, OCT angiography revealed outer retinal and retinal pigment epithelium (RPE) hyperreflective lesions with attenuated OCT signal in the underlying choroid, but careful examination allowed us to identify a single lesion with decreased choriocapillaris flow outside the signal attenuation. Optical coherence tomography angiography obtained after healing of lesions revealed areas of hypointense circular flow voids clustered in groups surrounded by either isointense or hyperintense signal background. Point-by-point evaluation revealed these flow voids did not correspond to areas of RPE thickening or focal pigmentary changes. Larger hypointense lesions were observed and did correlate with pigmentary changes. CONCLUSION: Our case series demonstrates choriocapillaris flow abnormalities in acute APMPPE extending beyond the OCT lesions, and distinct residual vascular abnormalities in healed APMPPE lesions on OCT angiography. Our findings support a primary ischemic insult to the photoreceptors and RPE, but choriocapillaris flow abnormalities could be secondary to (OCT invisible) retinal and RPE involvement. The lack of understanding of the etiology along with the inability to visualize most of the choroid in acute lesions precludes definite conclusions about the true pathogenesis of APMPPE.

Multimodal Imaging of Serpiginous Choroiditis.

PURPOSE: To report a case of atypical serpiginous choroiditis with previously unreported findings on optical coherence tomographic angiography. CASE REPORT: A 35-year-old otherwise healthy man had a 1-week history of vision loss in his right eye. The visual acuity in right eye was counting fingers at 1 meter. Fundoscopy showed a classic peripapillary serpiginous lesion and a solitary macular lesion. Fundus fluorescein angiography revealed early hypofluorescence of active lesions with gradual increase in fluorescence across the phase of angiogram. Optical coherence tomography showed hyperreflectivity in outer retinal layers and loss of ellipsoid zone band. The patient was treated with oral prednisone and visual acuity returned to near normal. The inflammation recurred once the patient discontinued corticosteroid therapy. The flare-up was treated with intravenous methylprednisolone followed by oral steroids. Oral azathioprine was added as a steroid-sparing agent and oral prednisone was tapered slowly and discontinued. The visual acuity returned to normal with settlement of all lesions after initiating azathioprine. Optical coherence tomography showed reintegration of retinal anatomy. No recurrence was seen after discontinuation of corticosteroids. Optical coherence tomographic angiography in resolved serpiginous choroiditis was consistent with loss of choriocapillaris homogeneity. CONCLUSIONS: Serpiginous choroiditis may manifest with multifocal lesions and may be confused with relentless placoid chorioretinitis. However, it ends up in a typical geographic scar. Optical coherence tomography can be used to monitor the changes in retinal structure. Choriocapillaris changes as seen on optical coherence tomographic angiography may be a possible mechanism behind the development of choroidal neovascularization in later stages of the disease.

Course of disease in multifocal choroiditis lacking sufficient immunosuppression: a case report.

BACKGROUND: Multifocal choroiditis with panuveitis is a rare disease. The educational merit of this case presentation results from the good documentation and the impressive ocular fundus pictures. CASE PRESENTATION: We illustrate the 3-year course of disease in a 22-year-old myopic white woman with multifocal choroiditis with panuveitis and secondary choroidal neovascularization. The activity of the disease was evaluated clinically by optical coherence tomography and fluorescein angiography. Choroidal neovascularization was treated by intravitreal bevacizumab (2.5 mg/0.1 ml). Our patient lacked systemic therapy for the first 11 months because of noncompliance. CONCLUSIONS: The case is remarkable as the delayed onset of peripheral lesions and the additional existence of high myopia made diagnosis difficult. In addition, it demonstrates that full outbreak of disease with multiple central and peripheral fundus lesions and secondary choroidal neovascularization can develop without systemic treatment.
