Bartonella Henselae Related Unilateral Anterior Uveitis and Subsequent Multifocal Retinitis in a Case Under Certolizumab Treatment.

Introduction: A case of ocular bartonellosis under anti-tumour necrosis factor treatment is described. Case description: A 29-year-old woman with psoriasis who had been on certolizumab treatment was examined with a left visual deterioration following a fever bout, malaise, and placoid erythematous rashes on her neck. As there was acute anterior uveitis in her left eye, it was recommended to stop certolizumab treatment for a possible infectious aetiology. However, her physician elected to continue the certolizumab treatment. Ten days later, the patient noticed further visual decline despite the topical steroid treatment. This time, there were scattered yellow-white small retinitis foci at the left posterior pole. Infectious agents were searched and while Bartonella henselae antibodies were negative for immunoglobulin M, the immunoglobulin G titre was 1/80. Clinical findings were improved with the systemic treatment of oral trimethoprim-sulfamethoxazole (160/800 mg twice daily for six weeks) and azithromycin (500 mg once daily for two weeks). Discussion: Though extremely rare, ocular bartonellosis should be kept in mind in patients on anti-tumour necrosis factor treatment as rapid and accurate diagnosis may end up with an excellent visual outcome and full recovery. LEARNING POINTS: Anti-tumour necrosis factor treatment is fraught with several ocular side effects including myositis, corneal infiltrates, scleritis, uveitis, optic neuritis, retinal vasculitis and ophthalmoplegia.When a new uveitis episode occurs in cases undergoing anti-tumour necrosis factor therapy, its cause poses a diagnostic challenge as it can have either an infectious or a non-infectious nature.Though very rare, ocular bartonellosis may also occur in immunocompromised individuals and a prompt diagnosis and appropriate treatment can lead to an excellent visual recovery.

Tubulointerstitial Nephritis and Uveitis Syndrome During the COVID-19 Pandemic: A Case Series.

Objectives: To report the ocular findings, laboratory results, and management of patients with tubulointerstitial nephritis and uveitis syndrome (TINU), whose numbers increased during the 2019 coronavirus disease (COVID-19) pandemic. Materials and Methods: Demographic characteristics, ophthalmic examination findings, laboratory results including polymerase chain reaction (PCR) test for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), serum SARS-CoV-2 immunoglobulin G (IgG) antibody, and treatment of patients diagnosed with TINU between March 2020 and March 2022 were evaluated retrospectively. Results: The study included 19 eyes of 10 patients (6 female/4 male). The mean age was 13.5±2.4 years (range: 8-16 years). The mean follow-up duration was 13.5±6.1 months (range: 6-24 months). All patients presented with anterior uveitis. Anterior uveitis was bilateral in 9 patients (90%) and unilateral in 1 patient (10%). Posterior segment findings were normal in 8 patients (80%), and bilateral optic disc edema was observed in only 2 patients (20%). None of the patients had a previous SARS-CoV-2 infection and/or vaccination history. The SARS-CoV-2 PCR test was negative in all patients at presentation. The SARS-CoV-2 IgG antibody test was reactive in 7 patients (70%). Recurrent uveitis developed in 8 patients (80%) during follow-up. Systemic immunomodulatory therapy was required for the control of ocular inflammation in 7 patients (70%) with severe uveitis flare-ups. Conclusion: TINU is a multisystemic autoimmune disease, especially in response to environmental triggering factors such as viral infections. Although TINU is a rare disease, the number of cases increased during the COVID-19 pandemic. SARS-CoV-2 antibodies were detected at a significant rate of 70% in these patients, who did not have a history of SARS-CoV-2 infection and vaccination. Previous asymptomatic SARS-CoV-2 infection in children may be a triggering factor in the development of TINU.

Fundus topographical distribution patterns of ocular toxoplasmosis.

BACKGROUND: To establish topographic maps and determine fundus distribution patterns of ocular toxoplasmosis (OT) lesions. METHODS: In this retrospective study, patients who presented with OT to ophthalmology clinics from four countries (Argentina, Turkey, UK, USA) were included. Size, shape and location of primary (1°)/recurrent (2°) and active/inactive lesions were converted into a two-dimensional retinal chart by a retinal drawing software. A final contour map of the merged image charts was then created using a custom Matlab programme. Descriptive analyses were performed. RESULTS: 984 lesions in 514 eyes of 464 subjects (53% women) were included. Mean area of all 1° and 2° lesions was 5.96±12.26 and 5.21±12.77 mm2, respectively. For the subset group lesions (eyes with both 1° and 2° lesions), 1° lesions were significantly larger than 2° lesions (5.52±6.04 mm2 vs 4.09±8.90 mm2, p=0.038). Mean distances from foveola to 1° and 2° lesion centres were 6336±4267 and 5763±3491 µm, respectively. The majority of lesions were found in temporal quadrant (p<0.001). Maximum overlap of all lesions was at 278 µm inferotemporal to foveola. CONCLUSION: The 1° lesions were larger than 2° lesions. The 2° lesions were not significantly closer to fovea than 1° lesions. Temporal quadrant and macular region were found to be densely affected underlining the vision threatening nature of the disease.

A Case Series of Cat-Scratch Disease with Ocular Manifestations: Clinical Findings and Treatment Approach.

Objectives: To present the clinical and demographic characteristics, imaging findings, diagnosis and treatment approach in cases of cat scratch disease (CSD) with ocular involvement. Materials and Methods: The records of 19 patients followed-up and treated between 2010 and 2020, including detailed ophthalmological examinations, imaging findings, and treatment approach, were evaluated retrospectively. Results: Twenty-three eyes of 19 patients, 7 female (37%) and 12 male (63%), were included in the study. The mean age was 34.1±13.3 (range: 11-56) years, and the mean follow-up duration was 12.6±18.0 (range: 1-81) months. Unilateral involvement was observed in 15 cases (79%). Cat contact was reported in 14 cases (74%). In 6 cases (32%), flu-like symptoms were present before the ocular complaints. The mean visual acuity (VA) at presentation was 0.42±0.36 (range: 0.001-1.0). Anterior uveitis was observed in 3 eyes (13%). Posterior segment findings included neuroretinitis in 14 (61%), superficial retinal infiltrate(s) in 8 (35%), papillitis in 3 (13%), branch retinal artery occlusion in 2 (8%), and cilioretinal artery occlusion in 1 (4%) of the eyes. All cases were positive for Bartonella henselae immunglobulin (Ig)M and/or IgG. Systemic antibiotic therapy was administered to all patients. Intravenous pulse or oral corticosteroids were given, especially in cases with optic disc involvement. The mean final VA was 0.80±0.25 (range: 0.01-1.0). Conclusion: CSD may present with different ocular involvement patterns. Apart from the classical neuroretinitis and macular star appearance, patients may present with isolated optic disc edema, branch retinal artery occlusion, and retinal infiltrations. In such patients, cat contact history and Bartonella serology should be evaluated to differentiate CSD.

Changing face of non-infectious pediatric uveitis in the pre-pandemic and pandemic periods: a comparison study.

OBJECTIVE: Our aim in this study was to reveal the clinical features of pediatric uveitis in the pandemic period and to compare it with the pre-pandemic era. METHODS: This retrospective study included 187 children diagnosed with uveitis between the 11th of March 2017 and the 11th of March 2022. The patients were divided into two groups based on the date of diagnosis as follows; Group 1: Patients diagnosed in the pre-pandemic period (11th March 2017-11th March 2020); Group 2: Patients diagnosed in the pandemic period (12th March 2020-11th March 2022). Demographic data, characteristics of uveitis, underlying diseases, systemic treatment modalities, and complications were compared between the two groups. RESULTS: A total of 187 (pre-pandemic 71, and pandemic 114) pediatric uveitis patients were recruited to the study. Fifty one percent (51%) of the patients were female. The number of patients diagnosed with uveitis increased approximately twice during the pandemic period compared to the pre-pandemic period. The frequency of anterior uveitis was found to be significantly higher in the pandemic period than in the pre-pandemic period (p = 0.037). It was mostly presented as symptomatic uveitis. There was a decrease in the diagnosis of JIA-related uveitis. ANA positivity increased in the pandemic period (p = 0.029). The response to treatment was better and the complication rate decreased in the pandemic period. CONCLUSION: The present study involved a large number of pediatric patients with uveitis. There are some differences in the characteristics of pediatric uveitis cases comparing the pandemic period and the pre-pandemic period. This increased frequency and changing clinical features of pediatric uveitis seems to be a result of COVID-19 infection.

Sympathetic Ophthalmia: Demographic Characteristics, Clinical Findings, and Treatment Results.

Objectives: To evaluate the demographic characteristics, clinical findings, and treatment approach of patients with sympathetic ophthalmia (SO). Materials and Methods: The records of 14 patients with SO between 2000 and 2020 were retrospectively reviewed. The patients' Snellen best corrected visual acuity (BCVA), detailed ophthalmological examination, optical coherence tomography (OCT), enhanced depth imaging-OCT (EDI-OCT), fundus fluorescein angiography findings, and treatment approaches were recorded. Results: The study included the 14 sympathizing eyes of 14 patients with SO (7 female, 7 male). The mean age was 48.5±15.4 years (range: 28-75), and the mean follow-up duration was 55.1±48.7 months (range: 6-204). Ten patients (71%) had a history of ocular trauma and 4 (29%) had a history of ocular surgery. The time to symptom onset in the sympathizing eye after trauma or ocular surgery ranged from 15 days to 60 years. The most common posterior segment findings were optic disc edema (36%) and exudative retinal detachment (36%). In the acute period, the mean choroidal thickness value on EDI-OCT was 716.5±63.6 µm (range: 635-772) and decreased to 296±81.6 µm (range: 240-415) after treatment. Treatment with high-dose systemic corticosteroid was given to 8 patients (57%), azathioprine (AZA) to 7 (50%), AZA and cyclosporine-A combination to 7 (50%), and tumor necrosis factor-alpha inhibitors to 3 patients (21%). Recurrence was observed in 4 patients (29%) during follow-up. At last follow-up, BCVA values were better than 20/50 in 11 (79%) of the sympathizing eyes. Remission was achieved in 13 patients (93%), but 1 patient (7%) lost her vision due to acute retinal necrosis. Conclusion: SO is a bilateral inflammatory disease that presents with granulomatous panuveitis after ocular trauma or surgery. Favorable functional and anatomical results can be obtained with early diagnosis and initiation of appropriate treatment.

Acute retinal necrosis: clinical features, management and outcomes.

PURPOSE: To evaluate the clinical features, treatment, and visual outcome of patients with acute retinal necrosis (ARN). METHODS: The data of patients were retrospectively reviewed. Factors associated with visual loss and factors affecting the risk for retinal detachment (RD) development were evaluated. RESULTS: Twenty-four eyes of 24 patients (7 female/17 male, mean age 43.7 years, mean follow-up period 31.0 months) were included. In ocular fluid samples of 15 (83%) out of 18 eyes, polymerase chain reaction (PCR) tests were positive for herpes simplex virus (seven eyes; 39%), varicella zoster virus (six eyes; 33%), cytomegalovirus (one eye; 6%), and adenovirus (one eye; 6%). Central retinal occlusive vasculitis was observed in three (13%) eyes. Systemic antiviral therapy was given to all patients, and additional intravitreal ganciclovir was administered in seven eyes (29%). The most common complication was RD (46%). There was no statistically significant difference in the frequency of RD between herpes simplex virus- and varicella zoster virus-positive patients (p = .617). The rate of RD was similar in eyes undergoing prophylactic laser photocoagulation (LPC), eyes undergoing vitrectomy + LPC, and eyes not undergoing LPC (p = .237). The number of eyes with final visual acuity below 20/200 was significantly higher in eyes with RD than without RD (p = .047). CONCLUSION: Prophylactic LPC and vitrectomy did not show clear benefits in terms of preventing RD development. RD was the most common complication and a major factor for a poor visual prognosis.

Half-fluence Photodynamic Therapy for Central Serous Chorioretinopathy in a Patient Receiving Corticosteroids for Behçet's Uveitis

Corticosteroid-induced central serous chorioretinopathy (CSCR) has been reported to develop in many intraocular inflammatory diseases and usually resolves spontaneously after discontinuation of corticosteroids. Patients without any improvement may require alternative therapies. In this case report, we present the case of a 35-year-old man with Behçet's disease who had complaints of decreased vision due to CSCR in his left eye while using systemic corticosteroids along with cyclosporine and azathioprine. Half-fluence photodynamic therapy (PDT) was performed because the CSCR did not regress despite discontinuation of systemic corticosteroids. After treatment, his visual acuity increased with complete resolution of the subfoveal fluid. Half-fluence PDT seems to be an effective and safe treatment for patients who develop acute CSCR while under systemic or local corticosteroid therapy for intraocular inflammatory diseases such as Behçet's uveitis and do not improve despite steroid discontinuation.

Comparison of Sociodemographic Features Between Behçet Uveitis and Other Non-infectious Uveitis

Objectives: To analyze and compare sociodemographic features between Behçet uveitis and other non-infectious uveitis. Materials and Methods: The data of adults with non-infectious uveitis in the nationwide uveitis database were analyzed and the sociodemographic features of patients with and without Behçet disease were compared. Results: This study included data of 4,978 eyes of 3,363 patients from 33 centers. The mean age at presentation was 38.7±13.3 (17-87) years. The mean age was 34.3±10.5 years in the Behçet uveitis group and 41.1±14.0 years in the other non-infectious uveitis group (p<0.001). Male predominance was seen in the Behçet uveitis group (67.7% vs. 32.3%) while female patients were more common in the other non-infectious uveitis group (54.4% vs. 45.6%, p<0.001). Regarding education level, the proportion of patients with low education was higher in the Behçet uveitis group than the other non-infectious uveitis group (49.6% vs. 43.4% in males, p=0.004; 61.5% vs. 59.2% in females, p=0.021). Having a low-income job or being currently unemployed, indicators of poor income, were more frequent in the Behçet uveitis group than in the other non-infectious uveitis group (32.0% vs. 22.8%, p<0.001). In the comparison of places of residence, the proportion of patients who lived in cities with low gross national product was 37.0% in the Behçet uveitis group and 31.1% in the other non-infectious uveitis group (p<0.001). Conclusion: Patients with Behçet disease had lower education level and socioeconomic status than patients with other non-infectious uveitis entities.

Analysis of Corneal Densitometry and Endothelial Cell Function in Fuchs Uveitis Syndrome.

OBJECTIVES: To evaluate corneal densitometry and endothelial cell properties in patients with unilateral Fuchs uveitis syndrome (FUS), and to compare results with unaffected contralateral eyes and healthy control subjects. METHODS: A total of 90 participants were included in this prospective cross-sectional study. Forty-five affected eyes of patients with FUS were regarded as group 1 (FUSa), 45 fellow eyes were regarded as group 2 (FUSf), and 45 healthy-control eyes were regarded as group 3. Corneal densitometry was measured with densitometry software of Scheimpflug Corneal Topography (Pentacam HR, Oculus GmbH, Wetzlar, Germany), whereas endothelial cell measurement was evaluated with specular microscopy (Tomey, EM4000, GmbH, Germany). RESULTS: The mean corneal densitometry values were higher in the midstromal (zones; 2-6, 6-10 mm), posterior (all zones), and total thickness (zones; 2-6, 6-10 mm) layers in the FUSa compared with FUSf and control eyes (P<0.05 for all comparisons). The mean values of average cell area and cell size characteristics (minimum, maximum, SD, and coefficient of variation) were higher; endothelial cell density and percentage of hexagonal cells were lower in the FUSa than in the other two groups (P<0.05 for all comparisons). There was a significantly strong correlation between specular microscopy parameters and posterior corneal densitometry values in the FUSa group. CONCLUSIONS: Impairment of endothelial cell function in affected eyes of patients with FUS resulted in increased values of corneal densitometry, especially posterior layer.

Behçet's disease uveitis: is there a need for new emerging drugs?

Introduction: Behçet's disease uveitis (BDU) is a potentially blinding disorder. Systemic treatment with disease-modifying anti-rheumatic drugs (DMARDs) is mandatory in patients with intraocular inflammation involving the posterior segment of the eye. Areas covered: This article discusses existing systemic treatment with corticosteroids and conventional and biologic DMARDs as well as adjunctive local therapy in BDU. An overview is provided for a wide range of biologic DMARDs that have shown promise or investigated in clinical trials. Most recently introduced biologic DMARDs and targeted synthetic DMARDs are also reviewed for their potential in the treatment of BDU. Expert opinion: The prognosis of patients with BDU has remarkably improved after the introduction of biologic DMARDs. An expanding therapeutic armamentarium will allow treatment of most refractory cases. The ultimate goal is to provide drug-free remission with preservation of 20/20 vision.

Unilateral Acute Macular Toxoplasmic Chorioretinitis Associated with White Dot-Like Choroidal Involvement Demonstrated on Indocyanine Green Angiography

A 9-year-old otherwise healthy boy was examined due to a 4-day history of visual decline in his right eye. Ophthalmological examination revealed an area of active retinochoroiditis in the right macula. Indocyanine green angiography (ICGA) demonstrated multiple hypocyanescent dots surrounding the active lesion extending 360 degrees towards the equator. Optical coherence tomography angiography (OCTA) exhibited dark dots on the choriocapillaris slab over areas corresponding to the hypocyanescent dots detected with ICGA. Full systemic examination and laboratory investigations were carried out. Toxoplasma gondii serology was positive. The diagnosis of toxoplasmic chorioretinitis with white dot-like choroidal involvement was made. Trimethoprim/sulfamethoxazole, azithromycin, and oral prednisolone were administered orally. On repeated ICGA 2 weeks later, the scattered hypocyanescent dots were significantly fewer in number. A month later, right visual acuity was improved, the macular chorioretinitis focus had become inactive, an epiretinal membrane had formed, and the dark dots on the choriocapillaris slab of OCTA were markedly diminished. ICGA may be helpful to observe possible, subtle choroidal involvement in patients with toxoplasmic chorioretinitis.

Behçet's Uveitis: Current Diagnostic and Therapeutic Approach

Behçet's disease is a chronic, multisystem inflammatory disorder characterized by relapsing inflammation. Although its etiopathogenesis has not yet been clarified, both the adaptive and innate immune systems, genetic predisposition, and environmental factors have all been implicated. It is more frequent and more severe in males in the third and fourth decades of life. The eye is the most frequently involved organ in the course of the disease. Ocular involvement (Behçet's uveitis) is characterized by bilateral recurrent non-granulomatous panuveitis and occlusive retinal vasculitis. Recurrent inflammatory episodes in the posterior segment may lead to permanent vision loss due to irreversible retinal damage and complications such as macular scarring, macular atrophy, and optic atrophy. Early and aggressive immunomodulatory treatment and the use of biologic agents when needed are crucial for preventing recurrences and improving visual prognosis.

Phacoemulsification in patients with uveitis: long-term outcomes.

BACKGROUND: To assess the long-term outcomes of phacoemulsification and intraocular lens (IOL) implantation in eyes with uveitis. METHODS: One hundred and five eyes of 81 patients, who underwent phacoemulsification and IOL implantation between January 2009 and July 2016, were included in this study. The demographic data, preoperative clinical findings, postoperative outcomes, and intraoperative and postoperative complications were recorded. All collected data and risk factors with regard to visual prognosis were analyzed with the help of the Statistical Package for the Social Sciences version 20.0 software program (IBM Corp., Armonk, NY, USA). RESULTS: During follow-up (mean: 35.2 ± 22.2 months), corrected distance visual acuity (CDVA) improved in 87.7% of all eyes and reached a level of 0.3 LogMAR or greater in 61.3% of eyes. Postoperative complications included posterior capsule opacification (50.9%), posterior synechiae (21.7%), cystoid macular edema (16%), epiretinal membrane (13.2%), glaucoma (11.3%), increased intraocular pressure (8.5%), and severe inflammation (6.6%). Uveitis recurred in 55.7% of all eyes. The risk for the development of cystoid macular edema was found to be associated with recurrence in the early postoperative period. Low visual acuity risk was 11.1-fold higher with macular scarring (p = 0.001) and 14-fold higher with optic atrophy (p < 0.001), respectively. CONCLUSIONS: With appropriate management during the pre- and postoperative periods, phacoemulsification and IOL implantation surgery can be safe and effective in eyes with uveitis. However, great caution must be taken to prevent complications both before and after the surgery.

Ultrastructural Analysis of the Anterior Lens Epithelium in Cataracts Associated with Uveitis.

PURPOSE: To investigate the transmission electron microscopic findings of lens epithelial cells (LECs) in patients with different subtypes of uveitis and to compare the findings with those in age-matched controls. METHODS: In this prospective case-control study, the anterior lens capsules were taken from 47 eyes of 47 patients with uveitis of different subtypes (17 with Fuchs uveitis syndrome [FUS], 13 with -Behçet's uveitis, 10 with idiopathic uveitis, and 7 with herpetic keratouveitis) and from 15 eyes of 15 control patients. RESULTS: In the FUS group, the LECs had homogeneous thickening and irregularity, with some small vacuoles and widespread, oval-shaped pigment clusters in some areas. In the Behçet uveitis group, there was evident thinning in the lens epithelium. The subepithelial tissue under the epithelium was thickened, and edematous areas were detected. In the idiopathic uveitis group, the LECs were thinner with small vacuoles, and the cubic structure of the LECs was transformed into a squamous one. Moreover, the LECs included some small vacuoles, similar to those in the FUS group. In the herpetic keratouveitis group, two prominent cell types were observed: (1) completely normal LECs and (2) degenerated-type LECs with pyknotic nuclei, condensation of chromatin, swelling in the cytoplasm, membrane ruptures, and intra-cytoplasmic inclusion bodies. In the control group, the LECs and all of their elements occurred in normal ultrastructural patterns, with the exception of a few small intraepithelial vacuoles, which were fewer in number and smaller than those in the FUS and idiopathic uveitis groups. CONCLUSION: The electron microscopic analysis of LECs of patients with different subtypes of uveitis revealed significant ultrastructural alterations, which may be related to the summation of oxidative stress and intraocular inflammation.

Multimodal imaging of type 1 aneurysmal telangiectasia in a Turkish female with giant arteriovenous aneurysmal malformation.

We present a case with giant arteriovenous aneurysmal malformation with different imaging modalities, including fundus photography, fundus fluorescein angiography, spectral domain optical coherence tomography, and optical coherence tomography angiography. A 43-year-old Turkish female presented with gradual blurred vision in her left eye. Her best-corrected visual acuity was 20/200. The fundoscopic examination revealed hard exudates and microaneurysms around the macula. Spectral domain optical coherence tomography showed cystoid macular edema and serous macular detachment. Fundus fluorescein angiography and optical coherence tomography angiography showed bean-like arteriovenous anastomosis between the inferior venous vascular arcade and the superior arterial vascular arcade. An en face angiogram using optical coherence tomography angiography within the deep capillary plexus also showed venous collateral channels across the horizontal raphe. The patient was diagnosed with arteriovenous aneurysmal malformation in association with type 1 aneurysmal telangiectasia. Ophthalmologists should note that giant aneurysmal lesions can occur in type 1 aneurysmal telangiectasia patients.

Aqueous humor IL-8, IL-10, and VEGF levels in Fuchs' uveitis syndrome and Behçet's uveitis.

PURPOSE: This study investigated the levels of interleukin (IL)-8, IL-10, and vascular endothelial growth factor (VEGF) in the aqueous humor (AqH) of patients with Behçet's uveitis (BU) and Fuchs' uveitis syndrome (FUS) during an inactive period and compared these levels with those in the AqH of noninflammatory healthy control subjects. METHODS: This prospective and case-control study included 33 patients (16 patients with BU and 17 patients with FUS) and 35 control subjects. IL-8, IL-10, and VEGF levels in the AqH were quantified by performing sandwich enzyme-linked immunosorbent assay. Kruskal-Wallis test was used to compare the cytokine levels in the different groups, and statistical significance was set at p < 0.05. RESULTS: IL-8 levels were significantly higher in the AqH of patients with BU and FUS than in the AqH of control subjects (p < 0.001 and p < 0.001, respectively). IL-10 levels were significantly lower in the AqH of patients with BU than in the AqH of patients with FUS and of control subjects (p = 0.001 and p < 0.001, respectively). Although VEGF levels were higher in the AqH of patients with FUS than in the AqH of patients with BU and of control subjects, the difference was significant only between patients with FUS and control subjects (p < 0.001). CONCLUSIONS: We observed a significant decrease in IL-10 levels in the AqH of patients with BU and a significant increase in VEGF levels in the AqH of patients with FUS compared to controls. IL-8 and VEGF levels showed no significant difference among uveitis patients.

Efficacy of Oral Valacyclovir Treatment in a Case with Acute Retinal Necrosis.

Acute retinal necrosis (ARN) is a rapidly progressive disease with poor prognosis, leading to visual loss in most cases. Rapid diagnosis and early anti-viral treatment significantly affect the course and prognosis of the disease. In this case report, we present a 34-year-old female patient referred to our clinic with symptoms of blurred vision and ocular pain diagnosed as acute glaucoma elsewhere. A clinical diagnosis of ARN was made and anti-viral treatment was started immediately. We herein describe our treatment approach to this particular case and discuss previously reported treatment modalities.

Clinical Characteristics of Fuchs' Uveitis Syndrome.

OBJECTIVES: To evaluate the clinical and demographic properties of Fuchs' uveitis syndrome (FUS) in Turkish patients. MATERIALS AND METHODS: The medical records of 161 patients with FUS followed in the Uveitis Division of Ulucanlar Eye Hospital between 1996 and 2014 were respectively reviewed. The mean age at diagnosis, sex, the number of affected eyes, follow-up period, clinical findings at presentation, complications during the follow-up period, medical and surgical treatments, and best corrected visual acuity at the initial and final visits were recorded. RESULTS: The study included 171 eyes of 161 patients diagnosed with FUS. Of the patients, 94 (58.4%) were female and 67 (41.6%) were male. The mean age at presentation was 35.2±11.0 (11-65) years. The mean follow-up period was 23.5±32.8 (2-216) months. Ten (6.2%) patients had bilateral involvement. The most common symptoms at presentation were decreased visual acuity or blurred vision in 63 (39.1%) and floaters in 19 (11.8%) patients. Clinical findings at presentation included diffuse small, round, white keratic precipitates in 128 (74.8%) eyes, anterior chamber reaction in 82 (47.9%), vitreous cells in 122 (71.3%), heterochromia in 47 (27.4%) and iris nodules in 32 (18.7%) eyes. During the follow-up period, elevated intraocular pressure occured in 31 (18.1%) eyes and the most common complication was cataract development (89 eyes, 52.0%). CONCLUSION: Heterochromia was observed in 27.4% of patients in our study. However, the diffuse small, round keratic precipitates, low-grade anterior chamber reaction and varying degrees of vitreous reaction are more common clinical characteristics that are helpful in making the diagnosis.

Fundus autofluorescence imaging of patients with idiopathic macular hole.

AIM: To investigate the role of fundus autofluorescence (FAF) both in the diagnosis and the preoperative and postoperative evaluation of patients with idiopathic macular hole (MH). METHODS: Forty eyes of 40 patients diagnosed as idiopathic MH between May 2010 and May 2011 were included in this retrospective study. All patients underwent full ophthalmologic examinations and imagings including fluorescein angiography, fundus autofluorescence (FAF) and optical coherence tomography. Thirty of these patients underwent MH surgery. FAF findings were associated with duration of symptoms, visual acuity at presentation, stage of MH, and postoperative anatomical correction. RESULTS: The mean duration of patients' symptoms was 3.8±2.0 (1-9) months. The MH was stage 2 in 4 (10%), stage 3 in 24 (60%) and stage 4 in 12 (30%) eyes. The median preoperative best corrected visual acuity was 20/200 (between 20/800 and 20/100). Twenty-eight of cases (70%) showed a stellate appearance with dark radiating striae. Having a visual acuity ≥20/200 was significantly more common in eyes with stellate appearance (P<0.001). The mean duration of symptoms was significantly shorter in eyes with stellate appearance (2.75±0.8 vs 6.33±1.61 months) (P<0.001). The frequency of stage 4 MH was significantly higher in eyes with non-stellate appearance (P<0.001). Anatomical correction of MH was achieved in 91.3% (21/23) of eyes with stellate appearance and 71.4% (5/7) of eyes without this appearance (P=0.225). CONCLUSION: Stellate appearance in FAF is associated with earlier stages of macular hole, better visual acuity at presentation, shorter duration of symptoms, thus more favorable prognosis.
