Toxoplasma chorioretinitis (TC) can exhibit atypical features in immunocompromised patients including bilaterality, extensive spread, multifocal presentation, large areas of retinal necrosis without adjacent retinal scarring, and diffuse necrotizing retinitis resembling the viral retinitis that may cause confusion in the differential diagnosis. The aim of this study was to present the clinical features of four eyes of three immunocompromised patients with active toxoplasma chorioretinitis. Two of the patients were female and one, male. Two patients had hematological malignancies and the remaining patient was under adalimumab treatment for ankylosing spondylitis. Visual complaints began 10 days to four months prior to TC diagnosis. All four eyes had mild-to-moderate anterior chamber cells together with severe vitritis on slit-lamp examination while there were solitary chorioretinitis lesions on fundoscopy. Despite all patients were negative for anti-toxoplasma immunoglobulin M, all were positive for immunoglobulin G. All three patients were successfully treated with a combined treatment of systemic and intravitreal anti-toxoplasmic drugs. Clinicians should be cautious for the possible toxoplasma chorioretinitis besides the other infectious entities when a new uveitis episode is detected in an immunosuppressed patient in order to avoid misdiagnosis and thereby wrong treatment.

PURPOSE
Studies on intestinal Behçet's disease (BD) complicated by myelodysplastic syndrome (MDS) are rare, and no established therapeutic guidelines exist. This study aimed to evaluate the clinical presentation and outcomes of patients with intestinal BD complicated by MDS (intestinal BD-MDS) and suggest a treatment strategy.
MATERIALS AND METHODS
Data from patients with intestinal BD-MDS from four referral centers in Korea who were diagnosed between December 2000 and December 2022 were retrospectively analyzed. Clinical features and prognosis of intestinal BD-MDS compared with age-, sex-matched intestinal BD without MDS were investigated.
RESULTS
Thirty-five patients with intestinal BD-MDS were included, and 24 (70.6%) had trisomy 8. Among the 35 patients, 23 (65.7%) were female, and the median age at diagnosis for intestinal BD was 46.0 years (range, 37.0-56.0 years). Medical treatments only benefited eight of the 32 patients, and half of the patients underwent surgery due to complications. Compared to 70 matched patients with intestinal BD alone, patients with intestinal BD-MDS underwent surgery more frequently (51.4% vs. 24.3%; =0.010), showed a poorer response to medical and/or surgical treatment (75.0% vs. 11.4%; <0.001), and had a higher mortality (28.6% vs. 0%; <0.001). Seven out of 35 patients with intestinal BD-MDS underwent hematopoietic stem cell transplantation (HSCT), and four out of the seven patients had a poor response to medical treatment prior to HSCT, resulting in complete remission of both diseases.
CONCLUSION
Patients with intestinal BD-MDS frequently have refractory diseases with high mortalities. HSCT can be an effective treatment modality for medically refractory patients with intestinal BD-MDS.

PURPOSE
Behçet's disease (BD) is an autoimmune chronic systemic inflammatory disease characterized by a versatile clinical spectrum. Growth arrest specific protein 6 (GAS6)/soluble AXL (sAXL) signaling pathway draws attention in the resolution of inflammation, and its deficiency is associated with chronic inflammatory, autoimmune diseases, as well as clearance of apoptotic cells by phagocytes - efferocytosis. In this study, it was aimed to investigate whether GAS6/sAXL, interleukin (IL)-10, nitric oxide (NO), and BCL-2 levels were associated with inflammation and efferocytosis contributes to the pathogenesis of BD.
METHODS
A total of 37 Behçet patients with ocular involvement and 30 healthy control subjects were included in this study. GAS6, sAXL, IL-10, NO, and BCL-2 levels were quantified using enzyme-linked immunosorbent assay (ELISA) method.
RESULTS
Serum GAS6, sAXL, IL-10, NO, and BCL-2 levels were significantly lower in patients with BD compared to the controls (P < 0.005, P < 0.001, P < 0.001, P < 0.001, and P < 0.001, respectively). In correlation analysis, research parameters decreased in patients with BD was significantly correlated with each other: GAS6-IL-10 (r = 0.585, P < 0.001), GAS6-BCL-2 (r = 0.541, P < 0.001), sAXL-BCL-2 (r = 0.696, P < 0.001), IL-10-NO (r = 0.717, P < 0.001), IL-10-BCL-2 (r = 0.759, P < 0.001), and NO-BCL-2 (r = 0.541, P < 0.001).
CONCLUSION
In conclusion, decreased serum BCL-2 level may be an indicator of increased apoptosis in these patients and decreased levels of GAS6/sAXL, IL-10, and NO may indicate insufficient clearance of apoptotic bodies released as a result of increased apoptosis in BD patients.

In recent years, adalimumab has been increasingly used in the chronic treatment of non-infectious uveitis. This case report aimed to describe a drug-induced adverse event in a 34-year-old man who presented with blurred vision and floaters in the right eye and was being treated for intermediate uveitis. The patient had started topical treatment with a diagnosis of uveitis at another center. Best corrected visual acuity at presentation was 0.8 (decimal) in the right eye and 1.0 in the left eye. On examination, the anterior chamber in the right eye was clear, with anterior vitreous cells and mild haze, and snow banking and vitreous opacities in the inferior periphery. Fluorescein angiography (FA) showed hyperfluorescence in the right disc and leakage in the inferior periphery. As the inflammation did not resolve with local treatment, systemic cyclosporine was administered, after which the patient exhibited vomiting and weakness. Cyclosporine was discontinued and adalimumab treatment was started. On examination 5 months later, bilateral vitreous cells and mild vitreous opacity were noted, and FA showed mild leakage in the inferior periphery bilaterally. In addition, a depigmented patchy vitiligo lesion was observed on the chin. Due to the persistence of intraocular inflammation and on the recommendation of the dermatology clinic, adalimumab treatment was continued and topical tacrolimus was started for the lesion. On examination 3 months later, the inflammatory findings had resolved and there was no progression of the vitiligo lesion. The patient's treatment was continued. Taken together with the previous literature findings, no pathology was found in the patient's systemic examination, suggesting that this lesion was a side effect of the treatment. Ophthalmologists should be alert for this side effect in patients receiving adalimumab.

INTRODUCTION
Uveitis-glaucoma-hyphema (UGH) syndrome is an infrequent but severe complication following intraocular lens implantation, characterized by anterior chamber inflammation and elevated intraocular pressure (IOP). This report presents a rare case of late-onset UGH syndrome induced by a well-positioned 1-piece posterior capsular intraocular lens (PCIOL) with a bulb of the haptics extruding through a peripheral capsular tear in a 90-year-old female, 17 years post-cataract surgery.
CASE PRESENTATION
The patient presented with persistent blurred vision, recurrent anterior uveitis, and uncontrolled IOP despite medical therapy. Extensive evaluation, including ultrasound biomicroscopy, failed to identify the underlying cause, necessitating surgical intervention to control IOP. During concurrent goniotomy and canaloplasty, a PCIOL haptics was discovered protruding through a peripheral capsular tear, establishing the diagnosis. Following PCIOL-haptic amputation and goniotomy and canaloplasty, the patient experienced significant improvement in symptoms and IOP control, with complete resolution of UGH syndrome.
CONCLUSION
This case highlights the necessity of considering atypical causes in persistent postoperative uveitis and IOP elevation and emphasizes the role of surgical intervention in managing complex cases.

Our purpose was to present a case of a patient diagnosed with herpes zoster ophthalmicus with multiple ocular manifestations. A 70-year-old Caucasian male presented to the hospital for headache and skin hyperesthesia on the scalp and forehead on the left side. The diagnoses of herpes zoster ophthalmicus and acute conjunctivitis were made for the left eye. The patient was followed up for 6 months and during that period the following diagnoses were made for the same eye: peripheral sterile corneal infiltrates, episcleritis, and hypertensive anterior uveitis. Herpes zoster ophthalmicus occurs when the reactivation of the dormant virus involves the ophthalmic division of the trigeminal nerve. The most frequent ocular presentations are conjunctivitis, keratitis, uveitis, episcleritis, and scleritis. The standard therapy consists of antivirals, such as acyclovir, valacyclovir, and famciclovir to limit the replication of the virus. The patient's risk factors, the course of treatment, and the severity of the disease, all affect the prognosis, which is highly variable. Prevention of the disease consists of vaccination with one of the following two vaccines, Zostavax and Shingrix. Final visual acuity for the left eye remained 1 despite numerous manifestations of the disease. VZV = Varicella-zoster virus, BCVA = best-corrected visual acuity, OU = both eyes, OD = right eye, OS = left eye, IOP = intraocular pressure, NCT = non-contact tonometer, ZVX = Zostavax vaccine.

To report patients who first presented with various ocular manifestations and eventually ascertained to have underlying dengue. A prospective study was conducted at multiple tertiary eye-care centers in India from 2012 to 2022. Cases reporting initially with ocular features along with fever/past history of fever over the last two weeks or with clinical features of dengue were selected. After an ophthalmological examination, patients underwent complete serological and biochemical analysis and those with reduced platelet counts were evaluated for dengue. Out of 564 cases, 15 patients were verified to be afflicted with dengue eventually. A rising trend of cases was seen every year and out of 15 cases, eight cases were reported during the Covid-19 pandemic (from 2020 to 2022), but were COVID-negative. 9 cases presented with acute redness followed by diminished vision. Seven cases presented a history of fever over the last few days and one had traveled from dengue endemic area. The various ocular presentations included subconjunctival hemorrhage, viral keratitis, anterior uveitis, sixth-nerve palsy, and vitreous hemorrhage. On serological examination, all 15 patients were detected to have low platelets. All cases responded well with supportive treatment and the ocular features subsided in all within a couple of weeks with good visual recovery. In a tropical nation, such as India, with endemic dengue zones and increasing figures of dengue lately, ophthalmologists must include dengue fever among the differential diagnoses in various ocular presentations like subconjunctival hemorrhage, viral keratitis, anterior uveitis, sixth nerve palsy, and vitreous hemorrhage. DHF = dengue hemorrhagic fever, PCR = polymerase chain reaction, RT-PCR = real-time automated reverse transcriptase (RT-PCR), SD = standard deviation, MAC-ELIS = IgM antibodies capture enzyme-linked immunosorbent assay, RE = right eye, LE = left eye, CECT = Contrast-enhanced computed tomography.

Fuchs Uveitis Syndrome (FUS), also known as Fuchs Heterochromic Iridocyclitis, is a chronic form of uveitis characterized by mild inflammation primarily affecting one eye. This study aimed to investigate the clinical and epidemiological features of FUS in an Iranian population. A retrospective analysis was conducted on 466 patients diagnosed with FUS at an ophthalmology center affiliated with Isfahan University of Medical Sciences between 2003 and 2021. The Kimura et al. criteria were used for FUS diagnosis. Demographic data, clinical characteristics, misdiagnosed cases, concurrent diseases, and associated ocular findings were analyzed. The study included 507 eyes of 466 FUS patients, with a mean age of 34.01 ± 11.25 years. Iris atrophy, keratic precipitates, and vitritis were common clinical findings. Heterochromia was an infrequent feature. Initial misdiagnosis occurred in 13 patients, with pars planitis being the most common incorrect diagnosis. Toxoplasmosis and multiple sclerosis were common concurrent diseases. Pediatric FUS cases were noted, possibly attributed to early-onset manifestations. Differences in clinical characteristics were observed when compared to other populations. This study provides insights into the clinical and epidemiological aspects of FUS in an Iranian population. Variations in clinical features, misdiagnosis patterns, and concurrent diseases were noted. Attention to specific clinical parameters can aid in accurate FUS diagnosis. Understanding these differences contributes to a better understanding of FUS presentation and its relationship with other diseases.

OBJECTIVE
To evaluate the effects of rosacea on ocular surface changes such as alterations in dry eye parameters, corneal densitometry, and aberrations, in comparison with healthy controls.
METHODS
A total of 88 eyes of 44 patients diagnosed with rosacea and 88 eyes of 44 healthy controls were enrolled in this cross-sectional study. All participants underwent a comprehensive dermatologic and ophthalmic examination and Tear Break-Up Time (TBUT) and Schirmer-1 tests were performed. The rosacea subtype and Demodex count and OSDI scores of all participants were recorded. Corneal topographic, densitometric, and aberrometric measurements were obtained using the Scheimpflug imaging system.
RESULTS
The mean age of the 44 patients was 41.2 ± 11.0 years of whom 31 (70.5%) were female. The mean TBUT and Schirmer-1 test values were significantly decreased and OSDI scores were significantly increased in the rosacea group compared to healthy controls (p < 0.01 for all). The most common subtype of rosacea was erythematotelangiectatic rosacea (70.4%). The severity grading of rosacea revealed that 18 (40.9%) patients had moderate erythema. The median (min-max) Demodex count was 14.0 (0-120) and the disease duration was 24.0 (5-360) months. The comparison of the corneal densitometry values revealed that the densitometry measurements in all concentric zones, especially in central and posterior zones were higher in rosacea patients. Corneal aberrometric values in the posterior surface were also lower in the rosacea group compared to healthy controls. The topographic anterior chamber values were significantly lower in the rosacea group.
STUDY LIMITATIONS
Relatively small sample size, variable time interval to hospital admission, and lack of follow-up data are among the limitations of the study. Future studies with larger sample sizes may also enlighten the mechanisms of controversial anterior segment findings by evaluating rosacea patients who have uveitis and those who do not.
CONCLUSION
Given the fact that ocular signs may precede cutaneous disease, rosacea is frequently underrecognized by ophthalmologists. Therefore, a comprehensive examination of the ocular surface and assessment of the anterior segment is essential. The main priority of the ophthalmologist is to treat meibomian gland dysfunction and Demodex infection to prevent undesired ocular outcomes.
