RELAY INTRASCLERAL 6-0 POLYPROPYLENE-ASSISTED INTRAOCULAR LENS FIXATION: A Retrospective Comparison With Modified Yamane Technique.

PURPOSE: To describe a new surgical technique that uses a relay suture to optimize sutureless scleral fixation of intraocular lens in eyes with capsular insufficiency and to evaluate the outcomes of this technique versus Flanged, double needle-guided, scleral fixation of intraocular lens with haptic trimming (modified Yamane approach). METHODS: Relay intrascleral 6-0 polypropylene sutures with flanges generated at the intraocular ends were used to fixate and securely hold a rigid intraocular lens with haptic eyelets against the inner scleral wall. The results were analyzed at 3-, 6-, and 12-month follow-up. RESULTS: This retrospective cohort study found that compared with the control group (n = 27), the relay-sutured group (n = 26) had greater mean changes in corneal astigmatism (0.44 vs. -0.52 diopters [D]) and fewer mean degrees of intraocular lens astigmatism (0.62 vs. 1.1 D). The mean intraocular lens decentration was comparable between both the groups; however, in the control group, there was a significant increase in intraocular lens tilt degrees from 3 to 12 months. Moreover, significantly higher proportions of patients with persistent macular edema and iris-optic capture were seen in the control group. CONCLUSION: The relay-sutured technique may be an alternative to flapless scleral fixation of intraocular lens and provides a stable intraocular lens position with acceptable complication rates.

Sutureless and Equipment-Free Technique for Contact Lens Viewing System During Vitreoretinal Surgery.

PURPOSE: To report a sutureless and equipment-free technique for contact lens wide-angle viewing system during vitreoretinal surgery. METHODS: A step-by-step procedure and a surgical video using this technique were proposed. RESULTS: This technique needs only three-finger control of contact lens either by the left hand (for the right-handed surgeon) or right hand (for the left-handed surgeon). The contact lens is not fixed to the environment (lid speculums, cannulas, corneoscleral limbus); therefore, it allows the surgeon to move and tilt the contact lens freely while keeping a clear view of the retina. CONCLUSION: The sutureless and equipment-free technique for contact lens viewing system during vitreoretinal surgery has been tried and tested, and it is practical and effective in the real world.

ISOLATED RETINAL VASCULITIS: Prognostic Factors and Expanding the Role of Immunosuppressive Treatment in Retinal Vasculitis Associated With Positive QuantiFERON-TB Gold Test.

PURPOSE: To identify prognostic factors for poor visual outcomes in patients with isolated retinal vasculitis and to elucidate the outcome of immunosuppressive treatment without the use of antituberculosis drugs for patients with retinal vasculitis associated with a positive QuantiFERON-TB Gold In-Tube (QFT) test. METHODS: A retrospective chart review was performed of patients presenting with retinal vasculitis. After the diagnosis of active retinal vasculitis had been confirmed by fluorescein angiography and other possible causes of retinal vasculitis had been excluded, patients were categorized into two groups by their QFT result. Potential associated factors between the poor and good visual outcome groups were statistically analyzed by the chi-square test and logistic regression model with generalized estimating equations. RESULTS: Seventy-three eyes (48 patients) were enrolled in this study. After univariate analysis, multivariate logistic regression analysis was performed and revealed that logMAR visual acuity at the initial visit ( P = 0.01) and outer retinal disruption ( P = 0.03) were the two factors significantly associated with poor visual outcomes. Systemic corticosteroids were administered without the use of antituberculosis drugs to all 16 cases of presumed tuberculous retinal vasculitis associated with positive QFT (26 eyes), 10 (63%) of whom were given nonsteroidal immunosuppressive drugs and achieved inflammatory control and treatment success. CONCLUSION: Risk factors leading to poor visual outcome in patients with isolated retinal vasculitis have been identified. Immunosuppressive treatment without antituberculosis drugs seems to be a promising regimen for selected patients with presumed tuberculous retinal vasculitis under vigilant care.

Catching the therapeutic window of opportunity in early initial-onset Vogt-Koyanagi-Harada uveitis can cure the disease.

PURPOSE: Vogt-Koyanagi-Harada (VKH) disease is a primary autoimmune granulomatous choroiditis that begins in the choroidal stroma. The aim of this review was to gather a body of evidence for the concept of a window of therapeutic opportunity, defined as a time interval following initial-onset disease during which adequate treatment will substantially modify the disease outcome and possibly even lead to cure, similar to what has been described for rheumatoid arthritis. METHODS: We reviewed the literature and consulted leading experts in VKH disease to determine the consensus for the notion of a therapeutic window of opportunity in VKH disease. RESULTS: We found a substantial body of evidence in the literature that a therapeutic window of opportunity exists for initial-onset acute uveitis associated with VKH disease. The disease outcome can be substantially improved if dual systemic steroidal and non-steroidal immunosuppressants are given within 2-3 weeks of the onset of initial VKH disease, avoiding evolution to chronic disease and development of "sunset glow fundus." Several studies additionally report series in which the disease could be cured, using such an approach. CONCLUSIONS: There is substantial evidence for a therapeutic window of opportunity in initial-onset acute VKH disease. Timely and adequate treatment led to substantial improvement of disease outcome and prevented chronic evolution and "sunset glow fundus," and very early treatment led to the cure after discontinuation of therapy in several series, likely due to the fact that the choroid is the sole origin of inflammation in VKH disease.

RUTHENIUM-106 BRACHYTHERAPY IN THE TREATMENT OF CIRCUMSCRIBED CHOROIDAL HEMANGIOMA.

PURPOSE: To examine the efficacy and safety of Ruthenium-106 plaque radiotherapy in the treatment of circumscribed choroidal hemangioma. METHODS: Twenty-one eyes of 21 patients diagnosed with symptomatic circumscribed choroidal hemangioma who underwent Ruthenium-106 plaque radiotherapy were included in the study. Clinical response, ancillary tests finding improvement, and major side effects were evaluated. RESULTS: From the initial to the 1-year follow-up visits, vision improved in 12 eyes (57%), was stable in 7 eyes (33%), and became worse in 2 eyes (10%). Based on fluorescein angiography and optical coherence tomography, subretinal fluid and cystoid macular edema resolved in all patients. Changes in logarithm of minimum angle of resolution visual acuity (P = 0.038); tumor thickness (P = 0.0001) and largest diameter (P = 0.007) on ultrasonography; and subfoveal thickness on optical coherence tomography (P < 0.0001), were statistically significant between the initial and the 1-year follow-up visits. Side effects as observed during the follow-up period included: radiation-related retinopathy in 5 (24%) eyes, radiation-related papillopathy in 1 eye (5%), and subretinal fibrosis in 2 eyes (10%). Subretinal fibrosis was the only permanent radiation-related side effect. CONCLUSION: Ruthenium-106 plaque radiotherapy is an effective and safe method of treatment for symptomatic circumscribed choroidal hemangiomas. The incidence of permanent visual loss is low with prompt treatment of complications.

Diabetic Retinopathy: Current Treatment and Thailand Perspective.

Diabetes mellitus is a common and chronic metabolic disorder involving multiple organ systems. Major eye involvements include diabetic macular edema (DME) and proliferative diabetic retinopathy (PDR). With a significantly increasing global number of cases of diabetes and the tendency towards an aging population, sight-threatening diabetic retinopathies are expected to increase from 37.3 million in 2011 to 56.3 million worldwide by 2030. Besides good glycemic and metabolic disease control, appropriate diabetic retinopathy (DR) screening and prompt treatments are crucial in order to minimize visual impairment from DR. The first-line therapy of DME is anti-vascular endothelial growth factor while panretinal photocoagulation laser remains the main treatment for PDR. Fortunately, in Thailand, these conditions have been included in the fundamental rights to eye care treatment, though an extension of geographic coverage and equal accessibility to care is needed. The Ministry of Public Health of Thailand has recently launched an area health initiative named the Service Plan, integrating 13 centers of excellence for certain specialties. As one of the 13 specialties, ophthalmic care includes centers of excellence in retina diseases. The policy implementation is aimed at drastically reducing preventable visual impairment resulting from various retinal diseases.

VISUAL OUTCOME AND POOR PROGNOSTIC FACTORS IN ISOLATED IDIOPATHIC RETINAL VASCULITIS.

PURPOSE: To describe the clinical course, visual outcome, and prognosis of isolated, idiopathic retinal vasculitis. METHODS: Eighty patients (150 eyes) with isolated, idiopathic retinal vasculitis were included. Demographic data, clinical data, complications at the initial visit and during follow-up, fluorescein angiography, and optical coherence tomography findings were collected from the Massachusetts Eye Research and Surgery Institution (MERSI) database from September 2005 to February 2015. RESULTS: Seventy-five (93.7%) patients required treatment with immunomodulatory therapy. Of those 75 patients, 60 (75%) patients were able to achieve durable remission. Factors which were independently significant predictive of poor visual outcome were lower initial visual acuity (OR: 3.78; 95% CI: 1.75-8.16; P = 0.001), cystoid macular edema (OR: 5.54; 95% CI: 1.81-16.99; P = 0.003), and macular ischemia (OR: 5.12; 95% CI: 1.12-23.04; P = 0.036). CONCLUSION: The majority (67.25%) of our patients enjoyed a good visual outcome (most recent visit best-corrected visual acuity equal to or better than 20/40 and within one line or better from the baseline) with immunomodulatory therapy. We found that cystoid macular edema, macular ischemia, and lower best-corrected visual acuity during the first consultation visit were significant independent risk factors for poor visual outcome.

BIRDSHOT CHORIORETINITIS LESIONS ON INDOCYANINE GREEN ANGIOGRAPHY AS AN INDICATOR OF DISEASE ACTIVITY.

PURPOSE: To determine whether classical indocyanine green angiography lesions in patients with birdshot chorioretinitis can be used to monitor disease activity. METHODS: A retrospective case series was performed on 26 eyes in 26 consecutive patients with birdshot chorioretinitis who had at least one indocyanine green angiography performed during disease activity and another during disease quiescence. Using Photoshop, the mean number, area, and area per spot on indocyanine green angiography were compared between disease activity and quiescence using a paired ratio test. RESULTS: The mean total lesion number, area, and area per spot during disease activity were 75.27 spots, 24,525 pixels, and 364 pixels/spots, respectively. The mean total lesion number, area, and area per spot size during disease quiescence were 28.35 spots (P < 0.01), 7,411 pixels (P < 0.01), and 279 pixels/spot (P = 0.12), respectively. CONCLUSION: There was a statistically significant decrease in the mean total area and number of lesions between the time of disease activity and disease quiescence (P < 0.01). Our results suggest that indocyanine green angiography has a role not only in diagnosis but also in monitoring treatment effectiveness; lesions can be reversible with treatment and their reappearance may be an indicator of disease relapse.

ANALYSIS OF THREE-DIMENSIONAL CHOROIDAL VOLUME WITH ENHANCED DEPTH IMAGING FINDINGS IN PATIENTS WITH BIRDSHOT RETINOCHOROIDOPATHY.

PURPOSE: To describe changes in three-dimensional choroidal volume and thickness with full raster scans of enhanced depth imaging optical coherence tomography in patients with birdshot retinochoroidopathy. METHODS: This prospective case series collected spectral domain optical coherence tomography images with the enhanced depth imaging technique from eight eyes of eight patients with birdshot retinochoroidopathy including four active patients (four eyes) and four quiet patients (four eyes). Fifty scans of each patient were manually segmented before automated built-in calibration software was used. RESULTS: Of all active patients, there were no statistically significant differences in the total choroidal volume and mean central choroidal thickness between the active and inactive phase over 6 months of follow-up. Alterations in choroidal parameters were evident and consistent after amelioration of inflammation, whereas the retinal volume and thickness remained stable. Regarding the eight inactive eyes at 6 months, the mean total choroidal volume and mean central choroidal thickness were significantly less than historical controls (P = 0.03 and P < 0.001, respectively). Persistent suprachoroidal hyporeflective space in two patients was noted despite the fact that clinical inflammation completely subsided at 6 months. CONCLUSION: Choroidal volume and thickness changes were consistent with inflammation in patients with birdshot retinochoroidopathy. Patients with inactive birdshot retinochoroidopathy have significant reduction in choroidal volume and thickness than do normal patients.

POOR PROGNOSTIC FACTORS IN PATIENTS WITH BIRDSHOT RETINOCHOROIDOPATHY.

PURPOSE: To identify prognostic factors for poor visual outcome in patients with birdshot retinochoroidopathy. METHODS: A case-control study of 98 patients with birdshot retinochoroidopathy (196 eyes) was evaluated with a follow-up period of at least 12 months. After exclusion of glaucoma, optic atrophy, and macular scar, the remaining eligible patients were categorized into two groups: poor visual outcomes and good visual outcomes. Poor visual outcome was defined as less than -6 mean deviation score on Swedish interactive threshold algorithm (SITA) short-wavelength automated perimetry (SWAP) test and abnormality (amplitude or implicit time) of 30 Hz flicker electroretinogram at 4-year follow-up and at the most recent visit for separate analysis. Potential factors between both groups were statistically analyzed by Chi-square test and logistic regression model. RESULTS: After the aforementioned exclusion, the remaining 77 patients with an average follow-up period of 52 ± 29 months (335 person-years, 36% with follow-up of more than 5 years) were divided into two groups. Sixteen patients were categorized as having poor visual outcome. Univariate analysis identified significant association of abnormal 30 Hz flicker electroretinogram amplitude (P = 0.004), implicit time (P = 0.002), and SITA SWAP mean deviation at the initial visit (P < 0.001) in the poor visual outcome group. Multivariate logistic regression analysis identified only SITA SWAP mean deviation to be associated with poor visual outcome (adjusted odds ratio, 32.50; 95% confidence interval [3.84-275.32]; P = 0.001) at the initial visit. To verify the model validity, an analysis of 42 patients at 4-year follow-up was performed and the outcome was confirmed (adjusted odds ratio, 8.80; 95% confidence interval [1.58-49.16]; P = 0.013). CONCLUSION: Worse SITA SWAP mean deviation at the initial visit is a predictor of poor visual outcome in patients with birdshot retinochoroidopathy, and may serve as a proxy marker for delayed effective steroid sparing therapy in patients with birdshot retinochoroidopathy.

Ocular involvement in systemic lupus erythematosus.

PURPOSE OF REVIEW: Many patients suffer from the ocular manifestations associated with systemic lupus erythematosus (SLE). Retinal vasculitis and optic neuritis are two of the most vision-threatening complications that can be associated with the disease. Ocular manifestations are often associated with wide-spread systemic inflammation which can be fatal. Thus, immediate recognition and treatment is vital for a positive outcome. RECENT FINDINGS: There is an array of medications available to ophthalmologists for treating the ocular manifestations of SLE. Treating the underlying systemic disease is crucial, as well as treating the active ocular complications. Recently, more attention has been placed on evaluating biologic agents' efficacy in treating the systemic condition. New therapies continue to emerge that have the potential to provide benefit to patients suffering from SLE. SUMMARY: SLE is a serious systemic condition that may first present with ocular manifestations. Thus, it is crucial for ophthalmologists to be equipped with the knowledge to detect and adequately treat the disorder to avoid vision/life-threatening complications. More research is needed to determine which therapy provides the best outcome for patients with limited side-effects.

SIMPLE REFIXATION OF A DISLOCATED HAPTIC OF FLANGED INTRAOCULAR LENS USING A 25-GAUGE NEEDLE.

PURPOSE: To report the development of a novel, simple-to-use technique for the salvage of a haptic of dislocated flanged intraocular lens during a retinal detachment surgery. METHODS: A 25-gauge regular-wall needle was prepared and threaded by the dislocated flanged haptic before the flanged haptic was heated and enlarged by low-temperature cautery. RESULTS: The dislocated flanged haptic was probably the result of too small of a diameter of the previously flanged haptic and was triggered by scleral indentation. The rescue technique required only a 25-gauge regular-wall needle to conduct the conventional procedure of flanged haptic intraocular lens fixation before being enlarged by low-temperature cautery. The intraocular lens remained centered and stable at a 3-month postoperative follow-up examination. CONCLUSION: The application of a 25-gauge needle in the salvage of a haptic of dislocated flanged intraocular lens is simple and effective without the need for trimming the flanged tip.

Appraisal of vitreous syphilis antibody as a novel biomarker for the diagnosis of syphilitic uveitis: a prospective case-control study.

PURPOSE: To determine the sensitivity and specificity of syphilis antibody tests in vitreous samples and to propose an algorithm using vitreous syphilis antibody as a supplementary test to confirm syphilitic uveitis (SU). METHODS: A prospective case-control study was conducted at the Retina and Uveitis Clinic from May 2017 to January 2020. Initially, patients were classified based on syphilis serology into group 1 (positive testing) and group 2 (negative testing). Group 1 was further divided into 2 subgroups (group 1A and 1B) depending on their relevant clinical manifestations and clinical improvement. Group 2 served as a control group. RESULTS: Thirty-eight patients were enrolled in the study: 14 in group 1A, 5 in group 1B, and 19 in group 2B. No patient was assigned to group 2A. All patients in group 1A, representing definite SU, completed syphilis test (rapid plasma reagin [RPR], enzyme immunoassay [EIA], and fluorescent treponemal antibody-absorption [FTA-ABS]) for vitreous, and all vitreous samples yielded positive results. Of the 5 subjects in group 1B, 3 cases were considered to be not SU with different conditions, and 2 were indeterminate for SU. They presented with different features not typical of SU, and they had variable and fewer positive syphilis antibody responses. The most sensitive test for detecting syphilis antibodies in vitreous was EIA (90.9%), followed by RPR (80.0%) and FTA-ABS IgG (78.9%). EIA and FTA-ABS had the highest specificity, detecting 100% of the syphilis antibody. CONCLUSIONS: Vitreous analysis of syphilis antibody can serve as a supplementary test to confirm SU in selected cases as the proposed algorithm.

Coexistence of choroidal melanoma and rhegmatogenous retinal detachment: a case report and literature review.

Introduction and importance: The simultaneous occurrence of rhegmatogenous retinal detachment (RRD) and choroidal melanoma is extremely rare, and diagnosis of choroidal melanoma in RRD patients is challenging. As a result, choroidal masses in RRD patients tend to be overlooked, resulting in delayed treatment. The authors report a rare case presenting with simultaneous choroidal melanoma and RRD, and the authors review the related literature. Case presentation: A 45-year-old Thai man who presented with inferior RRD and choroidal elevation in the left eye was examined using fundoscopy and ultrasonography. The presumptive diagnosis was simultaneous RRD and haemorrhagic choroidal detachment (CD). Vitrectomy and external drainage were attempted but were unsuccessful in draining fluid from the presumed haemorrhagic CD. Although the retina was reattached, the choroidal elevation remained unchanged. After being lost to follow-up, the patient returned later with severe proptosis in the left eye. MRI findings suggested a presumptive diagnosis including choroidal melanoma and choroidal metastasis, which choroidal melanoma was later confirmed through histopathological examination after exenteration. Clinical discussion: Important clinical clues were provided for distinguishing between choroidal melanoma and haemorrhagic CD in cases of coexisting RRD. Conclusions: In the differential diagnosis of RRD with suspicious choroidal elevation, the possibility of the presence of choroidal melanoma should be considered. In particular, in cases where haemorrhagic CD fails to drain during surgery, the possibility of underlying choroidal melanoma should be investigated.

The Classification of Common Macular Diseases Using Deep Learning on Optical Coherence Tomography Images with and without Prior Automated Segmentation.

We compared the performance of deep learning (DL) in the classification of optical coherence tomography (OCT) images of macular diseases between automated classification alone and in combination with automated segmentation. OCT images were collected from patients with neovascular age-related macular degeneration, polypoidal choroidal vasculopathy, diabetic macular edema, retinal vein occlusion, cystoid macular edema in Irvine-Gass syndrome, and other macular diseases, along with the normal fellow eyes. A total of 14,327 OCT images were used to train DL models. Three experiments were conducted: classification alone (CA), use of automated segmentation of the OCT images by RelayNet, and the graph-cut technique before the classification (combination method 1 (CM1) and 2 (CM2), respectively). For validation of classification of the macular diseases, the sensitivity, specificity, and accuracy of CA were found at 62.55%, 95.16%, and 93.14%, respectively, whereas the sensitivity, specificity, and accuracy of CM1 were found at 72.90%, 96.20%, and 93.92%, respectively, and of CM2 at 71.36%, 96.42%, and 94.80%, respectively. The accuracy of CM2 was statistically higher than that of CA (p = 0.05878). All three methods achieved AUC at 97%. Applying DL for segmentation of OCT images prior to classification of the images by another DL model may improve the performance of the classification.

Prevalence and associated factors of diabetic retinopathy in Chandrubeksa Hospital, Directorate of Medical Services, Royal Thai Air Force.

OBJECTIVE: To evaluate the prevalence and associated factors of diabetic retinopathy (DR) in patients with type 2 diabetes in the diabetes clinic at Chandrubeksa Hospital. MATERIAL AND METHOD: A cross-sectional study was performed on 261 type 2 diabetic patients at Chandrubeksa Hospital on January 2011. They all underwent fundus examination by ophthalmologists using indirect ophthalmoscope to check for any signs of DR. RESULTS: Retinopathy was presented in 67 (25.70%) patients who were categorized into non-proliferative and proliferative types, 23.4% and 2.3% respectively. The patients who received insulin treatment were more likely to have DR than those who had not (OR 3.95, 95% CI 1.86, 8.39). Those who had had diabetes for more than 5 years were more likely to have diabetic retinopathy than those with diabetes for a lesser amount of time (OR 2.36, 95% CI 1.28, 4.33). CONCLUSION: Insulin treatment and the duration of diabetes are the significant associated factors for developing diabetic retinopathy in type 2 diabetic patients. The authors emphasize the necessity of regular eye check-ups which can provide the patients with early detection so that treatment can begin before much damage occurs.

Effects of Ketoconazole on the Clinical Recovery in Central Serous Chorioretinopathy.

Purpose: Patients with hypercortisolism have been associated with a higher prevalence of the pachychoroid spectrum including central serous chorioretinopathy (CSCR), which may explain the inconsistency of therapeutic responses of the mineralocorticoid receptor antagonist because hyperaldosteronism has rarely been detected in patients with CSCR. Therefore, this study aimed to evaluate the effects of ketoconazole, the first-line cortisol inhibitor, on the resolution of subretinal fluid (SRF) in CSCR and to analyze correlations between choroidal thickness and steroid hormones. Patients and Methods: This retrospective cohort study included 41 naïve CSCR eyes of 41 patients categorized into control (20 eyes) and treatment (21 eyes) groups. Patients in the treatment group were administered oral ketoconazole at a daily dose of 400 or 600 mg for 3-6 weeks. At week 12, rescue laser therapy was applied to patients exhibiting persistent SRF. Thus, a survival analysis was performed to determine the time interval from presentation to clinical resolution of SRF. Secondary outcomes consisted of eyes with persistent SRF and factors affecting the therapeutic response. Results: The mean 24-hour urinary free cortisol (UFC) levels were elevated at 181 ± 70 and 150 ± 68 µg/day (range: 20-150) in the treatment and control groups, respectively (p = 0.21). After controlling for age and gender, baseline UFC levels were significantly associated with choroidal thickness in both eyes (p < 0.05). Ketoconazole significantly increased the CSCR resolution with the median time to resolution of 7 vs 16 weeks (p < 0.01) and decreased the proportion of eyes receiving rescue therapy at 12 weeks (23.8% vs 50%; p = 0.01). Prolonged CSCR durations were likely found in elderly patients with thick choroids in fellow eyes. Conclusion: Patients with CSCR showed elevated glucocorticoids, which further correlated with their choroidal thickness. Using cortisol blockers may shorten the duration of existing SRF.

Treatment for Epstein-Barr Virus-associated uveitis confirmed by polymerase chain reaction: Efficacy of Anti-Viral Agents and a literature review.

BACKGROUND: There are still many research challenges and unanswered questions in relation to Epstein-Barr virus-associated uveitis. These include the presence of Epstein-Barr virus (EBV) DNA in asymptomatic patients, its pathogenicity in the uveitis eye, and the role of antiviral therapy for EBV-associated intraocular inflammation. METHODS: This was a retrospective review of prospectively collected data from the Ophthalmology Department, Rajavithi Hospital between 2015 and 2020. A qualitative assay using multiplex real-time PCR was performed to detect pathogen genes from specimens obtained from a total of 344 patients. The main outcome measure was treatment success defined by clinical improvement and absence of viral DNA confirmed by PCR. RESULTS: Of the 35 cases, 24 with complete data were enrolled in the study, including 22 with post-treatment PCR results. Sixty-seven percent were HIV-infected, and other plausible causes or coinfection with other pathogens were found in 75% of patients. Cytomegalovirus (38%) was the most common co-infecting pathogen. The most commonly employed regimen was a combination of systemic acyclovir and intravitreal ganciclovir injection (58%). Of the 22 cases who had post-treatment PCR results, absence of detection of the virus by PCR in the intraocular fluid after treatment was demonstrated in 73% of patients. CONCLUSION: Patients with EBV infection can be simultaneously co-infected with other pathogens. Systemic acyclovir and ganciclovir achieved clinical improvement in most cases, and EBV infection was cured in the majority of patients.

Recalcitrant infectious uveoscleritis: A case report of a coinfection by Epstein-Barr virus and Talaromyces marneffei.

Introduction and importance: In an immunocompromised patient, there has never been a report of Epstein-Barr virus (EBV) and Talaromyces marneffei co-infection. Treatment with intravenous ganciclovir for EBV-associated uveitis has only been explored in a few cases. Case presentation: A 47-year-old HIV-positive female presented with scleral nodule and vascularized iris tumor in the left eye. After the ancillary laboratory workup, EBV was detected by polymerase chain reaction on aqueous humor and scleral tissue analysis. The lesion subsided completely with systemic and local ganciclovir therapy. Subsequently, recurrent scleral nodule with iris plaque developed and was pathologically diagnosed as Talaromyces marneffei. The employed treatment, including intravenous amphotericin B and intracameral amphotericin B injection, was successful in attaining a significant regression of the lesion. Clinical discussion: Although EBV treatment is debatable, our combination of systemic and local ganciclovir therapy demonstrated regression of EBV-caused scleral nodule and iris plaque. The organism's identification was complicated by Talaromyces marneffei, but it was easily treated. Conclusions: In HIV-infected patients, EBV-associated sclerouveitis can be successfully treated with systemic and local ganciclovir therapy, and there is a possibility of coinfection with Talaromyces marneffei.

The incidence, risk factor, and time to develop rheumatologic diseases after isolated inflammatory eye diseases: a 12-year cohort study.

OBJECTIVE: The incidence, risk factors, and time to diagnosis of rheumatologic disease (RD) in patients with isolated inflammatory eye diseases (IED) were investigated. MATERIAL AND METHODS: A 12-year bidirectional cohort study was conducted in IED patients who were tested for antinuclear antibody (ANA) and rheumatoid factor (RF). Patients with prior RD were excluded. Impacts of relevant symptoms, signs, and laboratory investigations were analyzed. RESULTS: Seventy-five patients presented with IED including scleritis, anterior uveitis (AU), retinal vasculitis (RV), keratopathy, and optic neuritis (OP). AU, RV, keratopathy, and OP were associated with RD development. The incidence of RD was 36% during 12 years. RD developed most frequently in AU (55.5%) and RV (22.2%). The longest duration for RD development was 5.5 years. Prevalence of positive ANA and RF were 57.3% and 13.3%, respectively. The three most common RDs developed after IEDs were spondyloarthropathy (44.4%), systemic lupus erythematosus (SLE) (18.5%), and Sjogren's syndrome (pSS) (11.1%). The risk factors of RD from univariate analysis were age below 35 years old at onset of IED [relative risk (RR) 3.45; 95% CI (1.13-10.55), p =0.026], positive pertinent findings from history [RR 2.125; 95% CI (1.39-3.25), p<0.001], and physical examination [RR 3.23; 95% CI (1.84-5.66), p<0.001]. Multivariable logistic regression showed that bilateral eye involvement of IED was the significant risk of RD [RR 4.33; 95% CI (1.57-11.96), p=0.004]. IED patients with bilateral eye involvement had shorter time to develop RD (p=0.018). Positive ANA was the predictor for SLE and pSS in RV or OP patients [RR 2.00; 95% CI (1.14-3.52), p=0.04]. CONCLUSIONS: IED with bilateral eye involvement was the risk of RD development. Positive ANA was the predictor of RD in RV and OP patients, but not for the other IEDs. Follow-up period of at least 5 years was required to identify RD. KEY POINTS: • Bilateral involvement of isolated inflammatory eye disease was a significant risk factor of rheumatologic disease development.
