OPTICAL COHERENCE TOMOGRAPHY ANGIOGRAPHY FINDINGS IN PATIENTS WITH CHRONIC THROMBOEMBOLIC PULMONARY HYPERTENSION.

PURPOSE: To investigate microvascular changes in the retina and choroid of chronic thromboembolic pulmonary hypertension (CTEPH) patients in comparison with healthy control subjects. METHODS: This observational clinical cohort study included 36 CTEPH patients (72 eyes) and 65 healthy control subjects (130 eyes). Optical coherence tomography (OCT) and optical coherence tomography angiography images were obtained from each participant using the AngioVue Imaging System (Optovue, Inc, Freemont, CA). RESULTS: A number of differences were found in the CTEPH cohort, including reductions in mean vessel density at the deep vascular complex of the macula and a reduction in mean subfoveal choroidal thickness. Furthermore, the CTEPH group displayed an increase in foveal avascular zone. The presence of at least one systemic disease, including arterial hypertension, diabetes, chronic coronary syndrome, and/or hyperlipidemia, in CTEPH patients increased the range of vascular complications. The presence of comorbidity was concomitant with a decrease in mean vessel density in the superficial vascular complex of the macula, excluding the fovea, and a decrease in mean vessel density in the radial peripapillary capillary plexus. CONCLUSION: Measurements of the foveal avascular zone and vessel density of the DVC and subfoveal choroidal thickness may be useful and sensitive predictors of retinal and choroidal circulation impairment in CTEPH patients without systemic disease.

Wide-Field Fluorescein Angiography in the Diagnosis and Management of Retinal Vein Occlusion: A Retrospective Single-Center Study.

BACKGROUND The aim of this retrospective study was to evaluate the role of wide-field fluorescein angiography (WF-FA) in the diagnosis and management of retinal vein occlusion (RVO) at a single center in Poland. MATERIAL AND METHODS This study included 106 patients (112 eyes) diagnosed with RVO (102 eyes) or impending RVO (10 eyes) (54% women and 46% men, aged 26 to 86 years). The medical records of the participants were reviewed in search of documentation on ocular and systemic diseases. Results of FA of central and peripheral retina and optical coherence tomography (OCT) scans, which had been used to establish treatment indications, were analyzed. WF-FA was performed with Spectralis HRA+OCT or Optos Tx200. RESULTS Actual RVO was found in 102 eyes. Of those cases, 46.1% were CRVO (central retinal vein occlusion), 40.2% branch retinal vein occlusion, 11.8% small tributary vein occlusion, and 1.9% hemispheric retinal vein occlusion. Neovascularization on an optic disc, neovascularization elsewhere, and veno-venous collateral vessels were observed in 32.3%, 17.4%, and 41.2% of the eyes, respectively. Peripheral ischemic zones were present in 59.8% of the eyes, in 20.6% of which, ischemia was not observed in the posterior pole. Dye leaks limited to peripheral vessels, peripheral vascular amputations, and central macular edema in OCT were observed in 17.6%, 43.1%, and 63.7% of the eyes, respectively. Retinal laser photocoagulation was conducted on 73.5% of the eyes. CONCLUSIONS Decision-making about management of patients with RVO should be done after physical examination and analysis of central and peripheral retina FA. In 20.6% of patients, assessment of the peripheral retina resulted in a change in treatment. The first changes suggestive of progression of thrombotic disease to the ischemic form appeared on the periphery in images from WF-FA.

WIDEFIELD FLUORESCEIN ANGIOGRAPHY IN THE DIAGNOSIS OF SUSAC SYNDROME.

PURPOSE: To present the clinical manifestations and results of key diagnostic investigations in patients with Susac syndrome, with special emphasis on the principal role of fluorescein angiography (FA) of the peripheral retina. METHODS: A retrospective analysis of medical records (collected 2000-2019) of 20 patients (15 women and five men), aged 20 to 51 years (mean age: 31.6 years) with complete or incomplete Susac syndrome diagnosed by an ophthalmic examination and widefield fluorescein angiography (WF-FA) by Spectralis and Optos Tx200. RESULTS: Fluorescein angiography abnormalities included vascular changes in the posterior pole in 64.7% and in the peripheral retina in 82.4%. Widefield FA abnormalities in the peripheral retina alone were seen in 35.3% and in the posterior pole, but without peripheral vascular involvement, in 17.6%. Secondary leakage from veins was noted in 58.8%. CONCLUSION: Widefield FA of the peripheral retina has a key role in cases of suspected Susac syndrome as it confirms the diagnosis and assesses disease activity. In addition to the characteristic findings, late-phase FA revealed leakage from veins which is not a typical sign. Patients experiencing migraine headaches may benefit from increasing awareness of neurologists and otologists who more promptly referred patients with suspected Susac syndrome for ophthalmologic evaluation and WF-FA of the peripheral retina.

Ocular Complications in Influenza Virus Infection.

Purpose: To describe a case series of ocular complications associated with upper respiratory tract infections. Methods: Four patients aged 21-61 years (three females, one male) had confirmed ocular complications connected with a general upper respiratory tract infection with myalgia and fever. Ophthalmological examination, including a visual acuity test, a slit-lamp exam, intraocular pressure measurements, fluorescein and indocyanine green angiography, optical coherence tomography (OCT), and diagnostic tests for influenza were performed in the patients (RT-PCR, HAI). Results: Acute posterior multifocal placoid pigment epitheliopathy (APMPPE) was diagnosed in three patients and serous macular detachment (SME) in one. Influenza virus infection was confirmed by molecular biological methods (RT-PCR) or the hemagglutination inhibition test (HAI) in two patients. All patients were treated with systemic prednisone. Conclusion: A coincidence between APMPPE and SME epitheliopathy and influenza virus infection was observed in different months of a given epidemic season.

A Retrospective Observational Study of Uveitis in a Single Center in Poland with a Review of Findings in Europe.

BACKGROUND This study aimed to review the causes, presentation, and clinicopathological associations of uveitis in a single department of ophthalmology in Poland, and to compare the findings with previously published studies from other European countries. MATERIAL AND METHODS Review of local patient records between 2005-2015 identified patients diagnosed with uveitis. Data obtained included age, gender, imaging findings, and laboratory diagnostic findings. A literature review identified 24 publications from 1976-2017 that reported observational data from patients with uveitis in Europe. Statistical analysis compared the findings. RESULTS Between 2005-2015, 279 patients were diagnosed with uveitis (mean age, 38.3±15.3 years) (61.6% women) including unilateral uveitis (60.5%), with posterior uveitis (48.4%), anterior uveitis (26.5%), and intermediate uveitis (12.9%). A general etiology was established in 76.3% and included ocular-specific syndromes (31.8%), infection (27.9%), and an association with systemic disease (16.8%), but 23.6% were unclassifiable. Specific causes of uveitis included toxoplasmosis (17.9%), Fuchs uveitis (12.2%), white dot syndromes (WDS) (10.4%), sarcoidosis (6.1%), toxocariasis (6.1%), HLA-B27-associated acute anterior uveitis (AAU) (5.7%), multiple sclerosis (4.7%), ankylosing spondylitis (3.6%) and herpesvirus infection (2.5%). Data from 26 published studies (24,126 patients with uveitis) from 12 European countries showed that idiopathic uveitis was most common (36.6%); the identified causes included toxoplasmosis (9.4%), WDS (7.2%), and Fuchs uveitis (6.1%). CONCLUSIONS In a single ophthalmic center in Poland, and throughout Europe, the causes of uveitis are varied. Genetic, geographic, social and environmental factors are likely to affect the cause of uveitis in different populations.

Correlation between Choroidal Neovascularization Shown by OCT Angiography and Choroidal Thickness in Patients with Chronic Central Serous Chorioretinopathy.

PURPOSE: To assess the occurrence of choroidal neovascularization (CNV) secondary to chronic central serous chorioretinopathy (CSCR) using optical coherence tomography angiography (OCTA) and correlate these findings with choroidal thickness (CT). MATERIALS AND METHODS: This retrospective study included 25 consecutive patients (43 eyes), mean age 48.12 ± 7.8 years, diagnosed with persistent CSCR. All patients underwent a complete ophthalmic examination, fluorescein angiography (FA), indocyanine green angiography (ICGA), optical coherence tomography, and OCTA. RESULTS: CNV was confirmed in 18.6% of eyes using FA and ICGA and in 25.6% of eyes using OCTA. All cases of CNV were associated with irregular retinal pigment epithelial detachment. CT was increased in the affected eyes (mean 491.05 ± 91.98), but there were no statistically significant correlations between CT and CNV and PED occurrence (p = 0.661 and p = 0.614, resp.) and between CT and duration of the disease (p = 0.940). CONCLUSIONS: OCTA detected CNV more frequently than other imaging modalities. CNV coexisted with irregular PED in all cases. CT was increased in eyes with chronic CSCR, but without any correlation with CNV occurrence; therefore, CT cannot be considered as a predictor of CNV occurrence. Further studies with a larger number of patients are needed to confirm these findings.

Observation and Clinical Pattern in Patients with White Dot Syndromes: The Role of Color Photography in Monitoring Ocular Changes in Long-Term Observation.

BACKGROUND The aim of this study was to assess the clinical course and distinctive features of different white dot syndromes (WDS) in patients attending the Ophthalmology Department, Medical University of Warsaw in the years 1995-2015. MATERIAL AND METHODS Sixty-two (62) patients (43 females and 19 males), aged 18 to 77 years, referred with a WDS were included in this prospective study, with observation period ranging from 5 months to 16 years. All patients underwent a complete ophthalmological examination and multimodal imaging studies. RESULTS In this cohort of 62 patients, the following WDS entities were identified: multifocal choroiditis with panuveitis (MFCPU), multifocal choroiditis (MFC), punctate inner choroidopathy (PIC), birdshot, acute posterior multifocal placoid pigment epitheliopathy (APMPPE), subretinal fibrosis and uveitis, multiple evanescent white dot syndrome (MEWDS), serpiginous choroiditis, and single cases of acute annular outer retinopathy (AAOR). CONCLUSIONS The study was performed at a Polish referral center and may to some extent reflect the varied geographical distribution of white dot syndromes, as none of the subjects was found to suffer from acute zonal occult outer retinopathy (AZOOR), acute macular neuroretinopathy (AMN), or diffuse unilateral subacute neuroretinitis (DUSN). Long-term follow-up is warranted by the evolution of lesions in the eye fundus, while management depends on correct diagnosis of WDS. When the posterior pole is involved in some cases of the WDS an immunosuppressive treatment, the use of the PDT or anti-VEGF injections were necessary.

Macular assessment using Optical Coherence Tomography in patients after uneventful phacoemulsification treated postoperatively with bromfenac, diclofenac or dexamethasone.

Aim: To assess macular thickness and volume using optical coherence tomography in patients treated with different anti-inflammatory agents after uneventful phacoemulsification. Material and methods: We analysed macular parameters using optical coherence tomography in 50 consecutive patients (mean age 70.5 years) who underwent uneventful phacoemulsification cataract surgery at the Ophthalmology Department, Medical University of Warsaw between March 2012 and January 2013. Patients were divided into 3 groups, according to 3 different anti- -inflammatory agents used during the postoperative period: group T receiving dexamethasone 0.1% (n=17), group Y receiving bromfenac sodium 0.09% (n=16) and group D receiving diclofenac sodium (n=17). We evaluated macular scans obtained the day before surgery and on days 1., 7., 30. and 90. postoperatively. Central subfield thickness, cube volume and cube average thickness were measured during the optical coherent tomography. The data was analysed statistically using the SAS 9.2 software. The graphs were prepared using the STATISTICA 12 software. Results: A significant increase in central subfield thickness was observed on day 30. postoperatively. However, there were no statistically significant differences in macular thickness between the study groups. Conclusions: Central retinal thickness increases after uneventful phacoemulsification despite active anti-inflammatory treatment and irrespective of the drug class used.

Evaluation of macular thickness after uneventful phacoemulsification in selected patient populations using optical coherence tomography.

PURPOSE: To quantitatively evaluate the effect of uneventful phacoemulsification on central retinal thickness and foveal volume with regard to the following factors: age, gender, systemic diseases: diabetes mellitus, arterial hypertension, coronary heart disease, phacoemulsification parameters (power and time); and to identify patient population at high risk of postoperative changes in macular thickness. MATERIAL AND METHODS: 87 eyes of 87 patients were examined. Foveal volume and central retinal thickness were measured using optical coherence tomography on postoperative days 1, 7, 30, 90 and 180. 10 patients did not complete the study, because of independent factors, these were excluded from the analysis. The results were analyzed within the predefined patient groups. RESULTS: There was a significant increase of central retinal thickness and foveal volume values on postoperative days 7, 30, 90 and 180, as compared to baseline (1st day after surgery). These values were higher in males and in patients with coronary heart disease. The presence of diabetes and hypertension was associated with the increased central retinal thickness, especially when both considered factors were present. No significant relation was found between the patient age and central retinal thickness during the 6-month's follow up. However, a significant association was observed between the age and the risk of retinal thickening. Higher phaco power (over 40.0%) settings increased both central retinal thickness and the risk of retinal thickening during the follow-up period. CONCLUSION: There is a significant increase in macular parameters after uneventful phacoemulsification. Despite downward trend, they remain elevated throughout the 6-month observation period. Diabetes and hypertension increase the risk of post-operative changes in macular thickness, especially if they coexist. Higher phaco power increases the risk of retinal thickening after cataract surgery. Early macular evaluation using the optical coherence tomography identifies patients at high risk of complications, who might benefit from additional anti-inflammatory treatment.

Optical coherence tomography in diagnosing, differentiating and monitoring of choroidal nevi - 1 year observational study.

OBJECTIVE: To assess the utility of the optical coherence tomography (OCT) in diagnosing, differentiating and monitoring of choroidal nevi situated in the posterior pole and optic disc area. MATERIAL AND METHOD: 116 consecutive patients (65 women, 51 men) aged 27-95 years, with choroidal nevus were included to the research. Routine ophthalmoscopic evaluation and OCT using the Zeiss Stratus OCT as well as fundus photography were performed in each patient. The OCT was used to assess the structure of the retina overlying the choroidal nevus, the retinal pigment epithelium (RPE) - choriocapillaris complex, as well as the anterior portion of the choroidal lesion. In 31 patients due to suspected malignant melanoma fluorescein angiography and ultrasound were additionally performed. Follow-up OCT was done after 12 months in 51 out of 85 patients with characteristics of choroidal nevi, and after 6 and 12 months in 27 patients with "suspicious" lesion. RESULTS: The basal dimension of the lesion ranged from 0.5 mm to 12 mm (mean 2.75mm), mean thickness was 1.25 mm. The pigmented lesion did not affect visual acuity. In 85 patients the lesion was flat or slightly elevated, without secondary changes in the retina. In 31 patients additional changes in the retina were observed - most frequently subretinal fluid. Two patients were eventually diagnosed with malignant melanoma. The follow-up OCT did not show progression in neither patients without secondary changes nor those with risk factors of malignancy. CONCLUSION: Optical coherence tomography enables detailed evaluation of the retina overlying the pigmented lesion. Secondary changes in the retina need additional exams and strict observation. OCT could be an additional tool in the evaluation of treatment of malignant melanoma.

[Peripheral retina in AMD patients]. / Zwyrodnienie plamki zwiazane z wiekiem a obwód siatkówki.

PURPOSE: To determine the frequency and possible correlation between peripheral retinal lesions and AMD. MATERIAL AND METHODS: 92 patients (50-89 years old), with AMD were evaluated by indirect ophthalmoscopy and biomicroscopy with triple mirror. The control group consisted of 92 patients without any lesions in macula and other retinal changes. RESULTS: At the AMD patients the peripheral benign lesions were found more frequent than in control group (p = 0.003, especially: drusen (p = 0.026), atrophy (p = 0.011), and chorioretinal degeneration (p = 0.001). CONCLUSIONS: The presence of peripheral retinal lesions may correlate with AMD evaluation.

Report of a case of malignant melanoma of the limbus (30-thy years of observation).

PURPOSE: To describe a case of a malignant melanoma of the limbus. MATERIAL AND METHODS: A 49-year-old female patient with a suspected malignant limbic melanoma in the left eye. The first signs appeared in 1975, manifested as reddening of the left eye on the temporal side with markedly dilated conjunctival vessels. In 1993, the lesion became pigmented and nine years later its progression was noted. In May 2003, lamellar keratoplasty of the left eye was performed under general anaesthesia. RESULTS: Histologic assessment--spindle cell malignant melanoma. The entire tumour was resected and the cosmetic result was very good. The results of accessory diagnostic studies were within normal limits. Over a 28-month follow-up period no local recurrence or metastases to other sites were observed. CONCLUSION: Patients with discoloration of the conjunctivae should be regularly evaluated by an ophthalmologist and an oncologist.
