Optic Disc Edema Is an Under-Recognized Feature of Birdshot Chorioretinitis.

BACKGROUND: Optic disc edema is a feature of many ophthalmic and neurologic conditions. It remains an underappreciated feature of birdshot chorioretinitis (BSCR), leading to delay in diagnosis and treatment. The purpose of our study was to identify clinical features that are concomitant with optic disc edema and suggest a diagnosis of BSCR. METHODS: Retrospective multicenter case series of 29 patients who were referred to a neuro-ophthalmologist or uveitis specialist for evaluation of disc edema and were ultimately diagnosed with BSCR. RESULTS: Fifty-four eyes of 30 patients, from the practices of 15 uveitis specialists, met the eligibility criteria. In addition to disc edema, concomitant features in all patients included vitritis, chorioretinal lesions, and retinal vasculitis. Visual recovery to 20/40 or better occurred in 26 of 29 patients. Visual acuity remained 20/100 or worse in 2 patients previously diagnosed with idiopathic intracranial hypertension, 1 patient previously diagnosed with optic neuritis, and 1 patient for whom treatment was delayed for years, leading to optic disc atrophy. CONCLUSIONS: Optic disc edema is a presenting feature in some cases of BSCR. A diagnosis of BSCR should be considered when disc edema occurs with vitritis, chorioretinal inflammation, and retinal vasculitis. Patients should be referred to a uveitis specialist for treatment.

Intravitreal Therapy for Uveitic Macular Edema-Ranibizumab versus Methotrexate versus the Dexamethasone Implant: The MERIT Trial Results.

PURPOSE: To evaluate the effectiveness of 3 different intravitreal treatments for persistent or recurrent uveitic macular edema (ME): dexamethasone implant, methotrexate, and ranibizumab. DESIGN: Single-masked, randomized controlled clinical trial. PARTICIPANTS: Patients with minimally active or inactive uveitis and persistent or recurrent uveitic ME in one or both eyes. METHODS: Patients at 33 centers were randomized 1:1:1 to receive 1 of the 3 therapies. Patients with bilateral ME received the same treatment in both eyes. MAIN OUTCOME MEASURES: The primary outcome, measured at 12 weeks, was reduction in central subfield thickness (CST) expressed as a proportion of baseline (CST per CST at baseline) assessed with spectral-domain OCT by readers masked to treatment assignment. Secondary outcomes included improvement and resolution of ME, change in best-corrected visual acuity (BCVA), and elevations in intraocular pressure (IOP). RESULTS: One hundred ninety-four participants (225 eligible eyes) were randomized to dexamethasone (n = 65 participants and 77 eyes), methotrexate (n = 65 participants and 79 eyes), or ranibizumab (n = 64 participants and 69 eyes). All received at least 1 injection of the assigned treatment. At the 12-week primary outcome point, each group showed significant reductions in CST relative to baseline: 35%, 11%, and 22% for dexamethasone, methotrexate, and ranibizumab, respectively. Reduction of ME was significantly greater in the dexamethasone group than for either methotrexate (P < 0.01) or ranibizumab (P = 0.018). Only the dexamethasone group showed a statistically significant improvement in BCVA during follow-up (4.86 letters; P < 0.001). Elevations of IOP by 10 mmHg, to 24 mmHg or more, or both were more common in the dexamethasone group; IOP spikes to 30 mmHg or more were uncommon overall and were not significantly different among groups. Reductions in BCVA of 15 letters or more were more common in the methotrexate group and typically were attributable to persistent ME. CONCLUSIONS: At 12 weeks, in eyes with minimally active or inactive uveitis, dexamethasone was significantly better at treating persistent or recurrent ME than methotrexate or ranibizumab. Risk of IOP elevation was greater with dexamethasone, but elevations to levels of 30 mmHg or more were infrequent.

Long-Term Safety and Efficacy of Adalimumab in Patients with Noninfectious Intermediate Uveitis, Posterior Uveitis, or Panuveitis.

PURPOSE: To evaluate long-term efficacy and safety of extended treatment with adalimumab in patients with noninfectious intermediate, posterior, or panuveitis. DESIGN: Open-label, multicenter, phase 3 extension study (VISUAL III). PARTICIPANTS: Adults who had completed a randomized, placebo-controlled phase 3 parent trial (VISUAL I or II) without treatment failure (inactive uveitis) or who discontinued the study after meeting treatment failure criteria (active uveitis). METHODS: Patients received subcutaneous adalimumab 40 mg every other week. Data were collected for ≤ 362 weeks. Adverse events (AEs) were recorded until 70 days after the last dose. MAIN OUTCOME MEASURES: Long-term safety and quiescence; other efficacy variables included inflammatory lesions, anterior chamber cell and vitreous haze grade, macular edema, visual acuity, and dose of uveitis-related systemic corticosteroids. RESULTS: At study entry, 67% of patients (283/424) showed active uveitis and 33% (141/424) showed inactive uveitis; 60 patients subsequently met exclusion criteria, and 364 were included in the intention-to-treat analysis. Efficacy variables were analyzed through week 150, when approximately 50% of patients (214/424) remained in the study. Patients showing quiescence increased from 34% (122/364) at week 0 to 85% (153/180) at week 150. Corticosteroid-free quiescence was achieved by 54% (66/123) and 89% (51/57) of patients with active or inactive uveitis at study entry. Mean daily dose of systemic corticosteroids was reduced from 9.4 ± 17.1 mg/day at week 0 (n = 359) to 1.5 ± 3.9 mg/day at week 150 (n = 181). The percentage of patients who achieved other efficacy variables increased over time for those with active uveitis at study entry and was maintained for those with inactive uveitis. The most frequently reported treatment-emergent AEs of special interest were infections (n = 275; 79 events/100 patient-years [PY]); AEs and serious AEs occurred at a rate of 396 events/100 PY and 15 events/100 PY, respectively. CONCLUSIONS: Long-term treatment with adalimumab led to quiescence and reduced corticosteroid use for patients who entered VISUAL III with active uveitis and led to maintenance of quiescence for those with inactive uveitis. AEs were comparable with those reported in the parent trials and consistent with the known safety profile of adalimumab.

Not All That Flickers Is Snow.

ABSTRACT: A woman presented with bilateral visual disturbances that had been diagnosed as visual snow. Dilated ophthalmic examination and multimodal imaging were strongly suggestive of birdshot chorioretinopathy, meriting initiation of systemic immunomodulatory therapy. Visual snow requires a thorough ophthalmologic exam to exclude other ocular diseases.

Long-term visual outcomes of endophthalmitis and the role of systemic steroids in addition to intravitreal dexamethasone.

BACKGROUND: The purpose of this study was to evaluate the role of systemic steroids in post-procedural endophthalmitis as the role of intravitreal steroids in treatment algorithms of endophthalmitis remain controversial. METHODS: This is a retrospective analysis from a single tertiary referral center of all patients older than 18 years old that developed presumed post-procedure endophthalmitis and were treated at our center from 2009 to 2018. RESULTS: Eighty-three patients were followed after being treated for post-procedural endophthalmitis that either received systemic steroids or did not around the time of diagnosis. Almost 30 % of all patients regained a final visual acuity of 20/40 or better, while 31.2% had poor visual outcomes of count fingers or worse. Non-clearing debris was the most significant long-term complication. Visual improvement plateaued in 67.7% by 1 month after diagnosis and initial treatment in both groups. There was no difference in visual outcomes when comparing the sixteen patients that received systemic steroids and the sixty-seven that did not; however, no enucleation or evisceration was required in patients receiving systemic steroids. Five patients that did not receive systemic steroids required an enucleation or evisceration due to a blind, painful eye. CONCLUSIONS: The use of systemic steroids does not seem to worsen long-term outcomes of endophthalmitis compared to those patients that did not receive them and they may prove beneficial in the most severe cases by reducing the risk of losing the globe altogether.

Genetics of age-related macular degeneration (AMD).

Age-related macular degeneration (AMD) is a progressive blinding disease and represents the leading cause of visual impairment in the aging population. AMD affects central vision which impairs one's ability to drive, read and recognize faces. There is no cure for this disease and current treatment modalities for the exudative form of the disease require repeated intravitreal injections which may be painful, are incompletely efficacious, and represent a significant treatment burden for both the patient and physician. As such, AMD represents a significant and important clinical problem.It is anticipated that in three years' time, 196 million individuals will be affected with AMD. Over 250 billion dollars per year are spent on care for AMD patients in the US. Over half of the heritability is explained by two major loci, thus AMD is considered the most well genetically defined of the complex disorders. A recent GWAS on 43,566 subjects identified novel loci and pathways associated with AMD risk, which has provided an excellent platform for additional functional studies. Genetic variants have been investigated, particularly with respect to anti-VEGF treatment, however to date, no pharmacogenomic associations have been consistently identified across these studies. It may be that if the goal of personalized medicine is to be realized and biomarkers are to have predictive value for determining the magnitude of risk for AMD at the genetic level, one will need to examine the relationships between these pathways across disease state and relative to modifiable risk factors such as hypertension, smoking, body mass index, and hypercholesterolemia. Further studies investigating protective alleles in populations with low AMD prevalence may lead to this goal.

ALPK1 missense pathogenic variant in five families leads to ROSAH syndrome, an ocular multisystem autosomal dominant disorder.

PURPOSE: To identify the molecular cause in five unrelated families with a distinct autosomal dominant ocular systemic disorder we called ROSAH syndrome due to clinical features of retinal dystrophy, optic nerve edema, splenomegaly, anhidrosis, and migraine headache. METHODS: Independent discovery exome and genome sequencing in families 1, 2, and 3, and confirmation in families 4 and 5. Expression of wild-type messenger RNA and protein in human and mouse tissues and cell lines. Ciliary assays in fibroblasts from affected and unaffected family members. RESULTS: We found the heterozygous missense variant in the ɑ-kinase gene, ALPK1, (c.710C>T, [p.Thr237Met]), segregated with disease in all five families. All patients shared the ROSAH phenotype with additional low-grade ocular inflammation, pancytopenia, recurrent infections, and mild renal impairment in some. ALPK1 was notably expressed in retina, retinal pigment epithelium, and optic nerve, with immunofluorescence indicating localization to the basal body of the connecting cilium of the photoreceptors, and presence in the sweat glands. Immunocytofluorescence revealed expression at the centrioles and spindle poles during metaphase, and at the base of the primary cilium. Affected family member fibroblasts demonstrated defective ciliogenesis. CONCLUSION: Heterozygosity for ALPK1, p.Thr237Met leads to ROSAH syndrome, an autosomal dominant ocular systemic disorder.

Periocular Triamcinolone vs. Intravitreal Triamcinolone vs. Intravitreal Dexamethasone Implant for the Treatment of Uveitic Macular Edema: The PeriOcular vs. INTravitreal corticosteroids for uveitic macular edema (POINT) Trial.

PURPOSE: To evaluate the comparative effectiveness of 3 regional corticosteroid injections for uveitic macular edema (ME): periocular triamcinolone acetonide (PTA), intravitreal triamcinolone acetonide (ITA), and the intravitreal dexamethasone implant (IDI). DESIGN: Multicenter, randomized clinical trial. PARTICIPANTS: Patients with uveitic ME. METHODS: Patients were randomized 1:1:1 to receive 1 of the 3 therapies. Patients with bilateral ME were assigned the same treatment for both eyes. MAIN OUTCOME MEASURES: The primary outcome was the proportion of baseline (PropBL) central subfield thickness (CST) at 8 weeks (CST at 8 weeks/CST at baseline) assessed with OCT by masked readers. Secondary outcomes included ≥20% improvement and resolution of ME, best-corrected visual acuity (BCVA), and intraocular pressure (IOP) events over 24 weeks. RESULTS: All treatment groups demonstrated improved CST during follow-up. At 8 weeks, each group had clinically meaningful reductions in CST relative to baseline (PropBL: 0.77, 0.61, and 0.54, respectively, which translates to reductions of 23%, 39%, and 46% for PTA, ITA, and IDI, respectively). Intravitreal triamcinolone acetonide (PropBL ITA/PropBL PTA, hazard ratio [HR], 0.79; 99.87% confidence interval [CI], 0.65-0.96) and IDI (PropBL IDI/PropBL PTA, HR, 0.69; 99.87% CI, 0.56-0.86) had larger reductions in CST than PTA (P < 0.0001). Intravitreal dexamethasone implant was noninferior to ITA at 8 weeks (PropBL IDI/PropBL ITA, HR, 0.88; 99.87% CI, 0.71-1.08). Both ITA and IDI treatments also were superior to PTA treatment in improving and resolving uveitic ME. All treatment groups demonstrated BCVA improvement throughout follow-up. Both ITA and IDI groups had improvements in BCVA that was 5 letters greater than in the PTA group at 8 weeks (P < 0.004). The risk of having IOP ≥24 mmHg was higher in the intravitreal treatment groups compared with the periocular group (HR, 1.83; 95% CI, 0.91-3.65 and HR, 2.52; 95% CI, 1.29-4.91 for ITA and IDI, respectively); however, there was no significant difference between the 2 intravitreal treatment groups. CONCLUSIONS: Intravitreal triamcinolone acetonide and the IDI were superior to PTA for treating uveitic ME with modest increases in the risk of IOP elevation. This risk did not differ significantly between intravitreal treatments.

Safety and Efficacy of Adalimumab in Patients with Noninfectious Uveitis in an Ongoing Open-Label Study: VISUAL III.

PURPOSE: To evaluate safety and efficacy of adalimumab in patients with noninfectious intermediate, posterior, or panuveitis. DESIGN: Phase 3, open-label, multicenter clinical trial extension (VISUAL III). PARTICIPANTS: Adults meeting treatment failure (TF) criteria or who completed VISUAL I or II (phase 3, randomized, double-masked, placebo-controlled) without TF. METHODS: Patients received adalimumab 40 mg every other week. Interim follow-up data were described from VISUAL III weeks 0 through 78. MAIN OUTCOME MEASURES: Disease quiescence, steroid-free quiescence, active inflammatory chorioretinal/retinal vascular lesions, anterior chamber cell grade, vitreous haze grade, best-corrected visual acuity (BCVA), and corticosteroid dose. Binary data were reported using nonresponder imputation (NRI), continuous data using last observation carried forward and as-observed analysis, and corticosteroid dose using observed-case analysis. Adverse events (AEs) were reported from first adalimumab dose in VISUAL III through interim cutoff. RESULTS: Of 424 patients enrolled, 371 were included in intent-to-treat analysis. At study entry, 242 of 371 (65%) patients had active uveitis; 60% (145/242, NRI) achieved quiescence at week 78, and 66% (95/143, as-observed) of those were corticosteroid free. At study entry, 129 of 371 (35%) patients had inactive uveitis; 74% (96/129, NRI) achieved quiescence at week 78, and 93% (89/96, as-observed) of those were corticosteroid free. Inflammatory lesions, anterior chamber grade, and vitreous haze grade showed initial improvement followed by decline in patients with active uveitis and remained stable in patients with inactive uveitis. BCVA improved in patients with active uveitis from weeks 0 to 78 (0.27 to 0.14 logMAR; left and right eyes; as-observed) and remained stable in patients with inactive uveitis. Mean corticosteroid dose decreased from 13.6 mg/day (week 0) to 2.6 mg/day (week 78) in patients with active uveitis and remained stable in those with inactive uveitis (1.5-1.2 mg/day). AEs (424 events/100 patient-years) and serious AEs (16.5 events/100 patient-years) were comparable with previous VISUAL trials. CONCLUSIONS: Patients with active uveitis at study entry who received adalimumab therapy were likely to achieve quiescence, improve visual acuity, and reduce their daily uveitis-related systemic corticosteroid use. Most patients with inactive uveitis at study entry sustained quiescence without a systemic corticosteroid dose increase. No new safety signals were identified.

Outcome of Treatment of Uveitic Macular Edema: The Multicenter Uveitis Steroid Treatment Trial 2-Year Results.

PURPOSE: To evaluate the 2-year outcomes of uveitic macular edema. DESIGN: Longitudinal follow-up of a randomized cohort. PARTICIPANTS: At baseline, 148 eyes of 117 patients enrolled in the Multicenter Uveitis Steroid Treatment (MUST) Trial had macular edema, and 134 eyes of 108 patients completed 2-year follow-up. METHODS: Patients enrolled in the study were randomized to either systemic immunosuppression or intravitreal fluocinolone acetonide implant therapy. Macular edema was defined as thickening of the retina (center point thickness≥240 µm) on time-domain optical coherence tomography (OCT) of macula. MAIN OUTCOME MEASURES: Improvement in macular edema (≥20% reduction in central point thickness on OCT), resolution of macular edema (normalization of thickness on OCT), and best-corrected visual acuity (BCVA). RESULTS: Between randomization and 2-years' follow-up, 62% and 25% of eyes in the systemic and implant groups, respectively, received at least 1 supplemental regional corticosteroid injection. By 2-years' follow-up, macular edema improved in 71% of eyes and resolved in 60%. There were no differences between treatment groups in the proportion of eyes with macular edema improving (systemic therapy vs. implant, 65% vs. 77%; P=0.20) and resolving (52% vs. 68%; P=0.28), but eyes randomized to implant had more improvement in macular thickness (median decrease of 180 vs. 109 µm in the systemic therapy group; P=0.04). Eyes with baseline fluorescein angiographic leakage were more likely to improve than those without (76% vs. 58%; P=0.03). Overall, there was a mean 5-letter (1 line) improvement in BCVA at 2 years. Mean changes in BCVA from baseline at 2 years by macular edema response status were: resolution, +10 letters; improvement without resolution, +10 letters (P=0.92); little to no change, 6 letters (P=0.19); and worsening, -16 letters (worsening acuity; P=0.0003). CONCLUSIONS: About two thirds of eyes with uveitic macular edema were observed to experience improvement in the edema and visual acuity with implant or systemic treatment. Fluocinolone acetonide implant therapy was associated with a greater quantitative improvement in thickness. Fluorescein angiography leakage was associated with a greater likelihood of improvement in macular edema.

Expert panel recommendations for the use of anti-tumor necrosis factor biologic agents in patients with ocular inflammatory disorders.

TOPIC: To provide recommendations for the use of anti-tumor necrosis factor α (TNF-α) biologic agents in patients with ocular inflammatory disorders. CLINICAL RELEVANCE: Ocular inflammatory diseases remain a leading cause of vision loss worldwide. Anti-TNF-α agents are used widely in treatment of rheumatologic diseases. A committee of the American Uveitis Society performed a systematic review of literature to generate guidelines for use of these agents in ocular inflammatory conditions. METHODS: A systematic review of published studies was performed. Recommendations were generated using the Grading of Recommendations Assessment, Development, and Evaluation group criteria. RESULTS: Numerous studies including controlled clinical trials have demonstrated that anti-TNF-α biologic agents (in particular infliximab and adalimumab) are effective in the treatment of severe ocular inflammatory disease. Based on these studies, the expert panel makes the following recommendations. CONCLUSIONS: Infliximab and adalimumab can be considered as first-line immunomodulatory agents for the treatment of ocular manifestations of Behçet's disease. Infliximab and adalimumab can be considered as second-line immunomodulatory agents for the treatment of uveitis associated with juvenile arthritis. Infliximab and adalimumab can be considered as potential second-line immunomodulatory agents for the treatment of severe ocular inflammatory conditions including posterior uveitis, panuveitis, severe uveitis associated with seronegative spondyloarthropathy, and scleritis in patients requiring immunomodulation in patients who have failed or who are not candidates for antimetabolite or calcineurin inhibitor immunomodulation. Infliximab and adalimumab can be considered in these patients in preference to etanercept, which seems to be associated with lower rates of treatment success.

Vitreomacular interface abnormalities in the Ghanaian African.

BACKGROUND/OBJECTIVE: Describe vitreomacular interface abnormalities (VMIA) using spectral-domain optical coherence tomography (SD-OCT), and correlations with age-related macular degeneration (AMD) grade in Ghanaian Africans. SUBJECTS/METHODS: Prospective, cross-sectional study of adults aged ≥50 years recruited in Ghana AMD Study. Participant demographics, medical histories, ophthalmic examination, digital colour fundus photography (CFP) were obtained. High-resolution five-line raster OCT, Macular Cube 512 × 128 scans, and additional line scans in areas of clinical abnormality, were acquired. SD-OCT VMI features classified by International Vitreomacular Traction Study Group system and relationships to AMD grade were evaluated. OUTCOMES: VMIA prevalence, posterior vitreous detachment (PVD), vitreomacular adhesions (VMA), vitreomacular traction (VMT), epiretinal membranes (ERM), correlations with AMD grade. RESULTS: The full Ghana AMD cohort included 718 participants; 624 participants (1248 eyes) aged ≥50 years (range = 50-101, mean = 68.8), 68.9% female were included in this analysis. CFP with OCT scans were available for 776 eyes (397 participants); 707 (91.1%) had gradable CFP and OCT scans for both AMD and VMI grading forming the dataset for this report. PVD was absent in 504 (71.3%); partial and complete PVD occurred in 16.7% and 12.0% respectively. PVD did not increase with age (p = 0.720). VMIA without traction and macular holes were observed in 12.2% of eyes; 87.8% had no abnormalities. VMIA was not significantly correlated with AMD grade (p = 0.819). CONCLUSIONS: This provides the first assessment of VMIA in Ghanaian Africans. VMIA are common in Africans; PVD may be less common than in Caucasians. There was no significant association of AMD grade with VMIA.

Fluorescein angiography versus optical coherence tomography for diagnosis of uveitic macular edema.

OBJECTIVE: To evaluate agreement between fluorescein angiography (FA) and optical coherence tomography (OCT) results for diagnosis of macular edema in patients with uveitis. DESIGN: Multicenter cross-sectional study. PARTICIPANTS: Four hundred seventy-nine eyes with uveitis from 255 patients. METHODS: The macular status of dilated eyes with intermediate uveitis, posterior uveitis, or panuveitis was assessed via Stratus-3 OCT and FA. To evaluate agreement between the diagnostic approaches, κ statistics were used. MAIN OUTCOME MEASURES: Macular thickening (MT; center point thickness, ≥ 240 µm per reading center grading of OCT images) and macular leakage (ML; central subfield fluorescein leakage, ≥ 0.44 disc areas per reading center grading of FA images), and agreement between these outcomes in diagnosing macular edema. RESULTS: Optical coherence tomography (90.4%) more frequently returned usable information regarding macular edema than FA (77%) or biomicroscopy (76%). Agreement in diagnosis of MT and ML (κ = 0.44) was moderate. Macular leakage was present in 40% of cases free of MT, whereas MT was present in 34% of cases without ML. Biomicroscopic evaluation for macular edema failed to detect 40% and 45% of cases of MT and ML, respectively, and diagnosed 17% and 17% of cases with macular edema that did not have MT or ML, respectively; these results may underestimate biomicroscopic errors (ophthalmologists were not explicitly masked to OCT and FA results). Among eyes free of ML, phakic eyes without cataract rarely (4%) had MT. No factors were found that effectively ruled out ML when MT was absent. CONCLUSIONS: Optical coherence tomography and FA offered only moderate agreement regarding macular edema status in uveitis cases, probably because what they measure (MT and ML) are related but nonidentical macular pathologic characteristics. Given its lower cost, greater safety, and greater likelihood of obtaining usable information, OCT may be the best initial test for evaluation of suspected macular edema. However, given that ML cannot be ruled out if MT is absent and vice versa, obtaining the second test after negative results on the first seems justified when detection of ML or MT would alter management. Given that biomicroscopic evaluation for macular edema erred frequently, ancillary testing for macular edema seems indicated when knowledge of ML or MT status would affect management.

The spectrum of COVID-19-associated chorioretinal vasculopathy.

Purpose: Although conjunctivitis represents the most common ocular manifestation of COVID-19 infection, sight-threatening retinal involvement has been reported. Herein, we report and characterize with multimodal retinal imaging 5 cases of acute vision loss secondary to presumed chorioretinal vasculopathy temporally associated with COVID-19 infection with varying severity, visual morbidity, and treatment response, and review the available literature on the association between COVID-19 infection and retinal microvascular changes. Design: Observational case series and literature review. Methods: Multicenter case series of 5 patients who presented to academic centers and private offices with acute vision loss temporally associated with COVID-19 infection. A review of the literature was conducted using online databases. Results: 10 eyes of 5 patients, 3 men and 2 women, with a mean age of 30.8 years (median 33, range 16-44) were described. All patients had a recently preceding episode of COVID-19, with symptomatology ranging from mild infection to life-threatening encephalopathy. Treatment for their retinal disease included topical, oral, intravitreal, and intravenous steroids, steroid-sparing immunosuppression, retinal photocoagulation, antivirals, and antiplatelet and anticoagulant agents. Treatment response and visual recovery ranged from complete recovery of baseline acuity to permanent vision loss and need for chronic immunosuppression. Conclusions and Importance: Clinicians should be mindful of the potential for vision-threatening retinal involvement after COVID-19 infection. If found, treatment with both anti-inflammatory therapy and anticoagulation should be considered, in addition to close monitoring, as some patients with this spectrum of disease may require chronic immune suppression and/or anti-VEGF therapy.

Patterns of Gene Expression, Splicing, and Allele-Specific Expression Vary among Macular Tissues and Clinical Stages of Age-Related Macular Degeneration.

Age-related macular degeneration (AMD) is a leading cause of blindness, and elucidating its underlying disease mechanisms is vital to the development of appropriate therapeutics. We identified differentially expressed genes (DEGs) and differentially spliced genes (DSGs) across the clinical stages of AMD in disease-affected tissue, the macular retina pigment epithelium (RPE)/choroid and the macular neural retina within the same eye. We utilized 27 deeply phenotyped donor eyes (recovered within a 6 h postmortem interval time) from Caucasian donors (60-94 years) using a standardized published protocol. Significant findings were then validated in an independent set of well-characterized donor eyes (n = 85). There was limited overlap between DEGs and DSGs, suggesting distinct mechanisms at play in AMD pathophysiology. A greater number of previously reported AMD loci overlapped with DSGs compared to DEGs between disease states, and no DEG overlap with previously reported loci was found in the macular retina between disease states. Additionally, we explored allele-specific expression (ASE) in coding regions of previously reported AMD risk loci, uncovering a significant imbalance in C3 rs2230199 and CFH rs1061170 in the macular RPE/choroid for normal eyes and intermediate AMD (iAMD), and for CFH rs1061147 in the macular RPE/choroid for normal eyes and iAMD, and separately neovascular AMD (NEO). Only significant DEGs/DSGs from the macular RPE/choroid were found to overlap between disease states. STAT1, validated between the iAMD vs. normal comparison, and AGTPBP1, BBS5, CERKL, FGFBP2, KIFC3, RORα, and ZNF292, validated between the NEO vs. normal comparison, revealed an intricate regulatory network with transcription factors and miRNAs identifying potential upstream and downstream regulators. Findings regarding the complement genes C3 and CFH suggest that coding variants at these loci may influence AMD development via an imbalance of gene expression in a tissue-specific manner. Our study provides crucial insights into the multifaceted genomic underpinnings of AMD (i.e., tissue-specific gene expression changes, potential splice variation, and allelic imbalance), which may open new avenues for AMD diagnostics and therapies specific to iAMD and NEO.

An inherited disorder with splenomegaly, cytopenias, and vision loss.

We describe a novel inherited disorder consisting of idiopathic massive splenomegaly, cytopenias, anhidrosis, chronic optic nerve edema, and vision loss. This disorder involves three affected patients in a single non-consanguineous Caucasian family, a mother and two daughters, who are half-sisters. All three patients have had splenectomies; histopathology revealed congestion of the red pulp, but otherwise no abnormalities. Electron microscopic studies of splenic tissue showed no evidence for a storage disorder or other ultrastructural abnormality. Two of the three patients had bone marrow examinations that were non-diagnostic. All three patients developed progressive vision loss such that the two oldest patients are now blind, possibly due to a cone-rod dystrophy. Characteristics of vision loss in this family include early chronic optic nerve edema, and progressive vision loss, particularly central and color vision. Despite numerous medical and ophthalmic evaluations, no diagnosis has been discovered.

Pyramidal Inflammatory Deposits of the Retinal Pigment Epithelium and Outer Retina in Ocular Syphilis.

PURPOSE: To evaluate the role of OCT in the diagnosis of uveitis secondary to syphilis. DESIGN: Consecutive, retrospective case series. PARTICIPANTS: All patients 18 years of age or older with ocular syphilis from 2 tertiary referral centers. METHODS: All patients who were diagnosed with intermediate uveitis, posterior uveitis, or panuveitis secondary to syphilis were included in the study (40 patients representing a total of 62 eyes) to identify important imaging features to aid in diagnosis. Patients underwent confirmatory serologic testing, OCT imaging, and dilated examination by a uveitis specialist. MAIN OUTCOME MEASURE: Hyperreflective retinal lesions on OCT. RESULTS: The mean age of the study population was 42.9 ± 12.16 years. Forty-five percent of the eyes included in this study harbored hyperreflective pyramidal lesions of the outer retina and retinal pigment epithelium on OCT. Fifty-four percent of eyes with these imaging findings did not show a placoid retinal lesion on examination. Sixty-eighty percent of the described outer retinal lesions on OCT resolved after treatment for syphilis. Visual acuity ranged from normal (20/20) to no light perception, with a mean of 20/43 at diagnosis, and improved significantly to a mean visual acuity of 20/26 after treatment (P < 0.05). Vision-threatening complications were seen in less than 5% of eyes and included both treatable and irreversible causes of vision loss, including retinal detachment, cystoid macular edema, and optic neuropathy. CONCLUSIONS: Patients treated for uveitis secondary to syphilis achieve good visual recoveries. Outer retinal lesions seen on OCT are common and can serve as an additional imaging finding of the disease.

Posterior scleritis and acute posterior multifocal placoid pigment epitheliopathy: A case of painful chorioretinitis and review of the current literature.

PURPOSE: To describe a patient who developed concurrent acute posterior multifocal placoid pigment epitheliopathy (APMPPE) and posterior scleritis. OBSERVATIONS: We describe a middle-aged woman that developed eye pain and photopsia. She was found to have a "T-sign" on ultrasound of the right eye and multiple, nearly confluent, ill-defined subretinal whitish lesions in both eyes. After an extensive laboratory evaluation and neuroimaging, her photopsia, pain with eye movements, and subretinal lesions began to regress on high dose systemic corticosteroids. CONCLUSIONS AND IMPORTANCE: This is the first reported case of bilateral APMPPE and concurrent posterior scleritis. Our case highlights the importance of performing a full review of systems, specifically eliciting neurological changes, and dilated eye examination in all new uveitis cases.

Efficacy of Adalimumab in Non-Infectious Uveitis Across Different Etiologies: A Post Hoc Analysis of the VISUAL I and VISUAL II Trials.

Purpose: To assess efficacy of adalimumab versus placebo in patients with active or inactive noninfectious intermediate, posterior, or panuveitis across different etiologies.Methods: VISUAL I (V-I) and VISUAL II (V-II) clinical trials included adults with active or inactive uveitis, respectively, randomized to receive adalimumab or placebo. In a post hoc subgroup analysis, time to treatment failure (TTF) starting at week 6 (V-I) or week 2 (V-II) was analyzed using the Kaplan-Meier method. Hazard ratios (HR) for TTF with 95% CI were calculated with Cox proportional hazards regression.Results: The analysis included 217 V-I patients and 226 V-II patients. Treatment failure occurred later and risk was significantly lower in patients with idiopathic uveitis receiving adalimumab versus those receiving placebo in V-I (HR = 0.50 [CI, 0.30-0.84]; P = .006) and V-II (HR = 0.43 [CI, 0.22-0.83]; P = .010).Conclusions: Treatment failure risk was lower in patients with idiopathic noninfectious uveitis receiving adalimumab versus those receiving placebo.
