RESUMO
PURPOSE: This study aimed to investigate the demographics, clinical characteristics, and management outcomes of patients with acute infectious endophthalmitis (AIE). METHODS: This retrospective chart review was conducted on all patients admitted with the clinical diagnosis of infectious endophthalmitis from 2017 to 2022. Demographic data, patients' clinical characteristics, the type of acute infectious endophthalmitis (post-operative, post-traumatic, bleb-associated, and endogenous endophthalmitis), the type of surgical procedure in the post-operative cases, the microbiologic analysis results of vitreous samples, therapeutic measures, and visual outcomes of patients were recorded. RESULTS: In this study, 182 participants, including 122 male (67%) and 60 (33%) female, were involved. The mean age of patients was 54.56 ± 21 years, with a range of 1-88 years old. The most prevalent type of AIE was post-operative (59.9%), followed by endogenous (19.2%), post-traumatic (17%), and bleb-associated (3.8%). The most common type of intraocular surgery in the post-operative subgroups of AIE patients was phacoemulsification (57.8%). The median (interquartile range) of the primary and final BCVA of patients was 1.5 (1.35, 1.85) and 0.65 (0.35, 1.35), respectively. Vitreous haziness grade (OR, 2.89; 95% CI, 1.11-5.74; p = 0.009) and the primary VA (OR, 60.34; 95% CI, 2.87-126.8; p = 0.008) revealed statistical significance for final vision loss. CONCLUSION: AIE is a devastating condition with poor visual outcomes, which presents with acute inflammatory signs and symptoms regardless of its type. However, prompt and appropriate treatment leads to visual recovery to a functional level in many patients.

OBJECTIVE: To assess the noninferiority of biosimilar aflibercept (P041, CinnaGen) to the originator aflibercept (AFL, Regeneron) in terms of efficacy, safety, and immunogenicity. DESIGN: This was a phase Ш, 52-week, multicenter, randomized, double-masked, and active control trial involving eyes in a 1:1 ratio. SUBJECTS: Patients with active subfoveal choroidal neovascularization secondary to age-related macular degeneration randomized into the 2 groups of P041 and AFL. METHODS: Patients received an injection of aflibercept every 4 weeks for 3 doses, followed by administration every 8 weeks up to week 48. MAIN OUTCOME MEASURES: The primary outcome was the noninferiority analysis of eyes maintaining vision at week 52. Secondary outcomes included the changes in visual acuity and retinal thickness, safety evaluation, and immunogenicity during the study. RESULTS: In total, 168 eyes of 168 patients were included. At week 52, the proportion of patients maintaining vision was 94.44% in the P041 group compared with 94.52% in the AFL group. The 95% confidence interval (CI) for the difference of maintaining vision from baseline did not exceed the predefined noninferiority margin of 10% (difference, -0.0008; 95% CI, -0.074 to 0.074; P = 0.98). Secondary outcomes indicated similar results in both arms (all P > 0.05). Safety measured outcomes and immunogenicity were similar between the 2 study groups. CONCLUSIONS: Biosimilar aflibercept was noninferior to AFL in eyes with neovascular age-related macular degeneration. Other efficacy and safety findings also indicated the similarity of 2 products.

We report the case of a 15-year-old boy with hypertensive retinopathy and Purtscher-like retinopathy eventually diagnosed with complement 3 glomerulopathy (C3G). The patient presented with bilateral severe painless visual loss and posterior pole cotton wool spots, optic disk and macular edema, and macular star-shaped hard exudate depositions, arterial narrowing, and venous tortuosity, indicative of hypertensive retinopathy (with an initial blood pressure of 210/130 mm Hg) and Purtscher-like retinopathy. He was subsequently diagnosed with C3G based on results of a kidney biopsy. There was a mild visual improvement on follow-up examination, and optic disk swelling and subretinal fluid and cotton wool spots resolved.

AIMS: Increased left ventricular (LV) wall thickness is frequently encountered in transthoracic echocardiography (TTE). While accurate and early diagnosis is clinically important, given the differences in available therapeutic options and prognosis, an extensive workup is often required to establish the diagnosis. We propose the first echo-based, automated deep learning model with a fusion architecture to facilitate the evaluation and diagnosis of increased left ventricular (LV) wall thickness. METHODS AND RESULTS: Patients with an established diagnosis of increased LV wall thickness (hypertrophic cardiomyopathy (HCM), cardiac amyloidosis (CA), and hypertensive heart disease (HTN)/others) between 1/2015 and 11/2019 at Mayo Clinic Arizona were identified. The cohort was divided into 80%/10%/10% for training, validation, and testing sets, respectively. Six baseline TTE views were used to optimize a pre-trained InceptionResnetV2 model. Each model output was used to train a meta-learner under a fusion architecture. Model performance was assessed by multiclass area under the receiver operating characteristic curve (AUROC). A total of 586 patients were used for the final analysis (194 HCM, 201 CA, and 191 HTN/others). The mean age was 55.0 years, and 57.8% were male. Among the individual view-dependent models, the apical 4-chamber model had the best performance (AUROC: HCM: 0.94, CA: 0.73, and HTN/other: 0.87). The final fusion model outperformed all the view-dependent models (AUROC: HCM: 0.93, CA: 0.90, and HTN/other: 0.92). CONCLUSION: The echo-based InceptionResnetV2 fusion model can accurately classify the main etiologies of increased LV wall thickness and can facilitate the process of diagnosis and workup.
RESUMO
PURPOSE: To evaluate changes in subfoveal choroidal thickness (SCT) in cases of tractional diabetic macular edema (DME) after pars plana vitrectomy (PPV). METHODS: This prospective study included 31 eyes of 31 patients who underwent PPV for the management of tractional DME. Best-corrected visual acuity (BCVA), SCT, and central macular thickness (CMT) were measured before the operation, as well as one, three, and six months following the surgery in the operated eyes and at baseline, as well as six months in the fellow eyes. RESULTS: The SCT decline in eyes with tractional DME was statistically significant six months postoperatively (P = 0.009). A statistically significant decline was observed in the CMT values one, three, and six months postoperatively in eyes with tractional DME (P = 0.02, P < 0.001, and P < 0.001, respectively). There was a statistically significant improvement in the visual acuity of the affected eyes three (P = 0.047) and six months (P = 0.017) postoperatively. CONCLUSION: After PPV for the treatment of tractional DME, a statistically significant decrease in the CMT values is detectable from the first month after surgery, followed by the improvement of BCVA from the third month. It is worth mentioning that a decrease was found in the SCT six months postoperatively.

PURPOSE: To report an unusual case of unilateral anterior segment large B-cell intraocular lymphoma (IOL) presenting as a recurrent hypopyon anterior uveitis. CASE PRESENTATION: A 55-year-old female was referred because of recurrent unilateral anterior hypopyon uveitis with partial response to topical corticosteroid. All of the laboratory tests, review of systems and ocular sampling results were unremarkable. Given a high concern for masquerades syndromes, cytological specimens were obtained 3 times and the last sample showed large B cell lymphoma. First, it appeared confined to the eye and initially responded favorably to local chemotherapy (methotrexate and rituximab) but later went on to develop systemic involvement. CNS lymphoma was detected on the third brain MRI 6 months following ocular involvement. At this time, systemic chemotherapy was started. In the last 18 months' follow-up, visual acuity was 20/30 in the right eye without posterior segment or fellow eye involvement. CONCLUSION: Unusual presentation of intraocular lymphoma as a unilateral isolated anterior hypopyon uveitis should be kept in mind. This report emphasizes the importance of precise work-ups and multiple ocular biopsies to confirm the diagnosis of intraocular lymphoma.
RESUMO
PURPOSE: To describe the optical coherence tomography (OCT) findings of toxoplasmic retinochoroiditis at different stages of activity. METHODS: Observational case series. RESULTS: A total of 32 eyes of 31 patients were included; 43 sets of OCT were reviewed. A total of 14 lesions were classified as active, 13 as partially active, and 16 as inactive. All active lesions demonstrated increased retinal thickness and reflectivity with blurring of details of retinal layers. Choroidal granuloma was detected in eight (61.5%) and serous retinal detachment in nine (64%). In partially active lesions, sustained thickening and/or attachment of posterior hyaloid face with fine epiretinal membrane was the hallmark. Scarified lesions showed decreased retinal and choroidal thickness starting from the periphery. Characteristic signs for decreased activity of a lesion seen in majority of both partially active and inactive lesions were RPE changes and retina-RPE approximation. We called this unique feature 'hourglass configuration'. CONCLUSION: Features in OCT are helpful to specify and monitor the activity of toxoplasmic retinochoroiditis.

PURPOSE: Herein, we report a case of primary intraocular lymphoma (PIOL) with the first presentation of bilateral Epstein-Barr virus- (EBV-) associated panuveitis. Case Presentation. A 69-year-old male was referred with a three-day history of blurred vision and pain and redness in his left eye following cataract surgery. Examination revealed panuveitis, vitritis, and necrotizing retinitis with retinal hemorrhage. A month later, the right eye was also involved. Polymerase chain reaction-based analysis of the vitreous sample was positive for EBV, and cytological evaluation was compatible with the diagnosis of B-cell lymphoma. A significant improvement was observed following serial intravitreal rituximab and methotrexate injections. The central nervous system and lungs were involved after 6 months, and the patient expired despite systemic chemotherapy. CONCLUSION: There may be an association between EBV panuveitis and primary intraocular B-cell lymphoma.
RESUMO
Theophylline is a potent adenosine receptor antagonist with indirect adrenergic effects that can lead to arrhythmias and metabolic abnormalities such as hypokalemia. Therapeutic toxicity cases have declined over the years mainly due to decreased recommended therapeutic doses and overall decreased usage of this medication due to newer available COPD treatment options. We present a clinical case of symptomatic supraventricular tachycardia resistant to adenosine therapy in a patient with theophylline use. This case highlights the importance of comprehensive medication review in acute settings to aid in identifying the underlying etiologies and initiating prompt treatments. It also signifies the importance of reviewing chronic medications in each outpatient visits to ensure continued indication for their use and be able to change them to newer agents per guidelines whenever possible.
RESUMO
BACKGROUND: Scleral buckling (SB) is usually considered an extraocular operation premeditated to have a low risk of sympathetic ophthalmia (SO). Here we report a rare case of presumed SO in a young female patient following SB. CASE PRESENTATION: A nineteen-year-old female patient was referred for visual loss in her left eye due to macula off inferior long-standing rhegmatogenous retinal detachment (RRD). The best corrected visual acuity (BCVA) was 20/400 in the left eye. SB with 360 degrees encircling band, an inferior segmental tire with one spot cryoretinopexy at the break site, and subretinal fluid drainage was performed. BCVA was improved to 20/80 and the retina was totally attached 1 week after the operation. The patient referred to the hospital 6 weeks later with severe visual loss in both eyes as counting finger 1 m. Patient examination indicated bilateral multifocal serous retinal detachment (SRD) and vitreous cells. The patient, diagnosed with SO, received intravenous corticosteroid pulse therapy and mycophenolate mofetil for treatment. The inflammation was controlled and SRD resolved after a 5-day intravenous treatment without being relapsed after 6 months. Consequently, BCVA became 20/20 and 20/50 in the right and left eye, respectively, after 6 months. The findings of systemic workup were negative for any extraocular disease or systemic involvement. CONCLUSION: Since SB is a procedure without manipulating intraocular tissues, it is considered to impose a low risk for SO. This report presented SO occurrence after successful SB. Some factors may induce SO, including inciting the choroid and retinal pigment epithelium with cryoretinopexy or perforating for drainage.
RESUMO
PURPOSE: To report a case of choroidal osteoma associated with reactivation of choroidal neovascularization (CNV) and development of focal choroidal excavation (FCE). CASE REPORT: A 34-year-old woman with choroidal osteoma complicated by CNV in the right eye for two years presented with deterioration of visual acuity in her right eye. A small retinal hemorrhage accompanied by subretinal fluid (SRF) was seen in the macular area of the right eye. Optical coherence tomography (OCT) showed that the inner retina was intact, and the outer retinal layers had outward displacement. SRF and a wedge-shaped choroidal depression were also seen. This choroidal excavation was not present on previous OCT images. The integrity of the inner retinal layers was maintained, and an optically clear space was present between the neurosensory retina and the retinal pigment epithelium. CONCLUSION: Choroidal osteoma can be complicated by CNV and FCE could occur as a consequence. Again, FCE can lead to CNV development. This cascade can deteriorate vision and sometime lead to permanent visual loss.
RESUMO
PURPOSE: To study the characteristics and visual outcome of cytomegalovirus retinitis in patients of a tertiary referral ophthalmology center. METHODS: This retrospective cross-sectional study included 16 patients who presented with CMV retinitis between February 2014 and January 2017. Demographics, clinical signs, course of treatment, and visual and anatomical results were analyzed. RESULTS: Twenty five eyes of 16 patients were included. Eleven (68.8%) were females. The mean age was 29.37 ± 17.12 (range 11-73) years. Involvement was bilateral in 9 (56.2%) cases. HIV serology was negative in all patients. Best-corrected visual acuity was 0.57 ± 0.55 logarithm of the minimal angle of resolution (LogMAR) at the time of presentation and decreased to 0.69 ± 0.55 LogMAR on final visit (P = 0.332). None of the patients participating in this study was HIV-positive. CONCLUSION: CMV retinitis is a devastating complication in immunosuppressed. The visual acuity usually decreases despite aggressive appropriate treatment. This observation supports the increasing incidence of CMV infection in non-HIV patients.

Purpose: To report a rare case of relapsing polychondritis with bilateral panuveitis as the first presentation of systemic disease Methods: A 26-year-old female presented with bilateral decreased vision, red eye and ocular pain underwent complete ocular examination, retinal imaging and systemic investigation. Results: Investigations revealed bilateral panuveitis associated with keratitis, retinal hemorrhages and retinal vasculitis. Following systemic work-ups and the pinna cartilage biopsy, diagnosis of relapsing polychondritis was made. Conclusion: Owing to debilitating and even life-threatening consequences of enigmatic relapsing polychondritis, high suspicion of the disease is of paramount importance in cases of retinal vasculitis and uveitis.

PURPOSE: To describe the demographic and clinical patterns of patients with uveitis referred to a tertiary center in northeastern Iran. METHODS: This cross-sectional retrospective study included 235 patients with uveitis who had been referred to the uveitis clinic of Khatam-Al-Anbia eye hospital, affiliated to Mashhad University of Medical Sciences, from February 2013 to March 2014. Data regarding patient age, sex, anatomical location of the disease, and etiologic and clinical features were analyzed. RESULTS: Mean patient age at the onset of uveitis was 35.75 ± 16.3 (range: 3-82) years. The ratio of females to males was 1.5 to 1. Sixty-four percent had bilateral involvement. The predominant type of inflammation was non-granulomatous (76%). Panuveitis (46.8%, 110 cases) was the most common form of uveitis followed by anterior (37%, 87 cases), intermediate (11.9%, 28 cases), and posterior uveitis (4.25%, 10 cases). The most common diagnoses were "idiopathic" in anterior and intermediate uveitis cases, toxoplasmosis in posterior uveitis group, and Behçet and Vogt-Koyanagi-Harada diseases in panuveitis cases. Overall, noninfectious causes (80.42%) of uveitis were more frequent than infectious causes (19.57%). The proportion of noninfectious uveitis was 82.75% in anterior uveitis, 78.18% in panuveitis, 92.85% in intermediate uveitis, and 50% in posterior uveitis. The most common associated systemic disease was Behçet disease. CONCLUSION: In contrast to most epidemiologic studies of uveitis, the clinical and etiologic patterns of uveitis were different in a tertiary referral center in northeastern Iran. Panuveitis was the most common clinical pattern in this study, and the most common associated systemic disease was Behçet disease.
RESUMO
OBJECTIVE: Diabetic macular edema (DME) is one of the most important sight-threatening complications in patients with diabetes. Owing to neuroprotective properties, crocin, as the main constituent in saffron, is thought to be useful in the treatment and prevention of diabetic maculopathy. The aim of this trial was to evaluate the effects of crocin as a supplement on reducing inflammation in patients with diabetic maculopathy. DESIGN: Double-masked, placebo controlled, phase 2 randomized clinical trial. METHODS: Participants: In this study, 101 eyes of 60 patients with refractory diabetic maculopathy to conventional therapy including macular photocoagulation and intravitreal injection of anti-vascular endothelial growth factor agent (bevacizumab) with or without steroid (triamcinolone) were studied in 3 groups. INTERVENTION: Patients in the crocin groups received 5 mg or 15 mg crocin tablets per day for 3 months, whereas patients in the placebo group received 1 placebo tablet per day during the study. The best-corrected visual acuity (BCVA) and central macular thickness (CMT) were measured before, every month during, and 3 months after intervention. Biochemical blood tests were also evaluated before and after trial. MAIN OUTCOME MEASURES: The BCVA and CMT were evaluated as the primary outcomes, whereas HbA1c and fasting blood sugar (FBS) were studied as the secondary outcomes in this trial. RESULTS: One hundred and one eyes were enrolled in this trial and were divided into 3 groups (crocin 5 mg, n = 34; crocin 15 mg, n = 33; and placebo, n = 34). According to our data, administration of crocin 15 mg tablet per day could significantly decrease HbA1c (P value = .024; 95% confidence interval [CI] 0.3-0.96), and CMT (P value = .005; 95% CI, 32.75-126.99) and improve BCVA (logMAR changes; P value = .012; 95% CI, 0.23-0.69) compared to the placebo group. Although administration of crocin 5 mg tablet per day could clinically improve HbA1c, FBS, CMT, and BCVA, the difference was not significant compared to the placebo group. CONCLUSION: This study indicated the effect of crocin as a potent antioxidant and neuroprotective for treatment of refractory DME in the short term; however, the clinical significance is yet to be proved in a study with larger sample size and longer duration of follow-up and also in treatment-naïve patients.

PURPOSE: This report describes a rare ocular complication in a burned patient. CASE REPORT: A 12-year-old girl was admitted to our burn center because of full thickness burn of 46% of her total body surface area. On the 23rd day of her stay, she complained of pain and decreased visual acuity in the right eye. Examination of this eye revealed panuveitis, dense vitritis, and a large chorioretinal abscess in the macular area; her best corrected visual acuity (BCVA) in this eye was hand motion. The left eye was completely normal. A smear and culture of the vitreous biopsy revealed the presence of Candida albicans. With a diagnosis of endogenous endophthalmitis due to fungal infection, the patient was treated with systemic fluconazole, intravitreal injection of Amphotericin B, and pars plana deep vitrectomy. After 6 months, the patient's final ocular examination revealed BCVA of counting fingers at two meters, a large macular scar, and quiescence of the intraocular infection. CONCLUSION: Burn patients treated with broad-spectrum antibiotics are at risk of candidemia and its complications, including endogenous endophthalmitis. Early diagnosis of endogenous endophthalmitis in high risk patients could prevent visual loss.
RESUMO
PURPOSE: To compare the results of narrow encircling band surgery with standard encircling scleral buckling for retinal detachments (RDs) with intrabasal or unseen breaks. METHODS: In a retrospective study, eyes with intrabasal or unseen breaks underwent narrow band implantation (group N) or standard encircling buckling plus wide tire placement (group W) and were followed for at least one year. RESULTS: A total of 112 eyes including 39 eyes in group N and 73 eyes in group W were studied. Preoperatively visual acuity of eyes in group N was significantly better (1.55 ± 0.9 vs. 1.93 ± 0.9 logMAR, P = 0.043). The two study groups (N and W) were comparable in terms of the extent of RD (2.8 ± 0.96 vs. 2.8 ± 0.93 quadrants), interval to surgery (88.3 ± 176.4 vs. 71.9 ± 135.4 days) and percentage of visible breaks (56.4% vs. 63%), respectively (all P values > 0.05). More atrophic holes were present in group W and more dialyses were reported in group N. The single operation success rate at 12 months was 69.2% in group N and 74% in group W (P = 0.1). The single operation success rate for eyes with unseen breaks was also comparable (66.7% vs. 85.7%, P = 0.157). Final corrected visual acuity was also similar (0.63 ± 0.44 vs. 0.85 ± 0.69 log MAR). The only factor influencing success rate was the type of retinal breaks (P = 0.04). Type of scleral buckling did not affect the single operation success rate (P = 0.460). CONCLUSION: Narrow encircling band surgery is a possible option with acceptable single operation success rate for RDs with intrabasal or unseen breaks.
