Intestinal microbiome: a new target for chalaziosis treatment in children?

Intestinal dysbiosis (changes in the gut commensal microbiome) is related to several ophthalmic diseases. The aim of this study was to verify whether oral specific probiotics can alter the clinical course of chalaziosis and its recurrence. A prospective comparative pilot study involving 26 children suffering from chalaziosis was conducted. Children were randomly divided into two groups. The first group received medical treatment (lid hygiene, warm compression and dexamethasone/tobramycin ointment for at least 20 days), and the second group received medical treatment plus a daily supplementation of oral probiotics (≥ 1 × 10^9 live cells of Streptococcus thermophilus ST10 (DSM 25246), ≥ 1 × 10^9 live cells of Lactococcus lactis LCC02 (DSM 29536) and ≥ 1 × 10^9 live cells of Lactobacillus delbrueckii subsp. bulgaricus (DSM 16606) with maltodextrin as the bulking agent (Probiotical S.p.A., Novara, Italy). All patients were evaluated at 2-week intervals for 3 months. If the lesion had not disappeared or decreased in size to 1 mm or less in diameter at the time of subsequent visits, the same procedure was repeated for another 3-month cycle. There was a significant difference in the time taken for complete resolution of the chalazion between the two groups in favour of the children receiving the probiotics. The treatment was not associated with any significant complications in either group. Trial registration: The trial was registered at clinical trials.gov under NCT04322500 on 25/03/2020 ("retrospectively registered").Conclusions: Modification of the intestinal microbiome with specific probiotics can alter the clinical course of chalaziosis in children by re-establishing intestinal and immune homeostasis. Probiotic supplementation can increase the effectiveness of traditional therapies by prompting the complete resolution of chalaziosis in a shorter amount of time, in an easy and feasible way. What is Known: • The intestinal microbiome plays a crucial role in several inflammatory diseases of the eye and is considered a therapeutic target. • Probiotics play a role in the prevention and treatment of different conditions in children. What is New: • In children probiotic supplementation is safe and effective. • Probiotic supplementation reduced the time required for complete resolution of the chalazion.

Unilateral proptosis in thyroid eye disease with subsequent contralateral involvement: retrospective follow-up study.

BACKGROUND: The purpose of this retrospective follow-up study is to evaluate the prevalence of patients with thyroid eye disease presenting with apparent unilateral proptosis and determine the occurrence of exophthalmos in contralateral non-proptotic eye over the time. Associated features with this event were evaluated. METHODS: A cohort of 655 consecutive patients affected by thyroid eye disease with a minimum follow-up of 10 years was reviewed. Exophthalmos was assessed by using both Hertel exophthalmometer and computed tomography (CT). The influence of age, gender, hormonal status and of different therapies such as corticosteroids, radiotherapy and surgical decompression on this disease progression was evaluated. RESULTS: A total of 89 patients (13.5%) (95% confidence interval [CI] 15%-10%) had clinical evidence of unilateral exophthalmos at the first visit. Among these, 13 patients (14%) (95% CI 22%-7%) developed subsequent contralateral exophthalmos. The increase of protrusion ranged from 2 to 7 mm (mean of 4.2). The time of onset varied from 6 months to 7 years (mean time: 29 months). Smoking status, young age and surgical decompression are significantly associated with development of contralateral proptosis (p< .05). CONCLUSIONS: Asymmetric thyroid eye disease with the appearance of unilateral exophthalmos at the initial examination is a fairly frequent event, while subsequent contralateral proptosis occurs less commonly. However, physicians should be aware that young patients, particularly if smokers, undergoing orbital decompression in one eye may need further surgery on contralateral side over time.

Scleral flaps, pars plana vitrectomy and gore-tex sutured posterior chamber intraocular lens placement: a case series and review of literature.

Introduction: Cataract surgery is one of the most common surgical procedures performed worldwide. Intraocular lens (IOL) implants are placed routinely in the capsular bag after successful cataract extraction. However, in the absence of adequate capsular support, IOL may be placed in the anterior chamber, fixated to the iris or fixated to the sclera. The purpose of this study is to report the clinical outcomes and safety profile of a trans-scleral sutured intraocular lens (IOL) technique using scleral flaps, vitrectomy, and Gore-Tex suture to place posterior chamber IOL. Methods: Retrospective, interventional case series of eyes undergoing scleral fixation of an IOL using Gore-Tex suture with concurrent vitrectomy. Ocular examination with the logarithm of the minimum angle of resolution visual acuity (logMAR BCVA), tonometry, and slit-lamp biomicroscopy was performed on all patients at 1, 3, 6, and 12 months after the operation. All post-operative complications were recorded. Results: Twenty-five eyes of 25 patients were included. Mean logMAR BCVA improved from 0.43 ± 0.36 (20\40 Snellen equivalent) preoperatively to 0.13 ± 0.18 (20\25 Snellen equivalent) postoperatively at 12 months (p<0.01). Indications included surgical aphakia (16) and dislocated lens implant (9). No cases of IOL opacification, suprachoroidal haemorrhage, post-operative endophthalmitis, IOL dislocation, Gore-Tex exposure, or retinal detachment were observed during the follow-up period. Conclusion: Ab externo scleral fixation of IOLs with Gore-Tex suture plus scleral flap is well tolerated and associated with a very low rate of suture exposition. Moreover, our study confirms excellent refractive outcomes after surgery.

Effect of minimonovision in bilateral implantation of a novel non-diffractive extended depth-of-focus intraocular lens: Defocus curves, visual outcomes, and quality of life.

PURPOSE: To evaluate overall patient satisfaction, spectacle independence, visual acuity, and prevalence of optical phenomena following bilateral implantation of a new non-diffractive extended depth-of-focus intraocular lens targeted for minimonovision. METHODS: Multicenter prospective case series. Postoperative far and near visual acuity at 3 months and patient quality of life by NEI-VFQ-25 questionnaire were assessed. Postoperative evaluation included defocus curves analysis, spectacle independence assessment, and recording of photic phenomena. RESULTS: The study enrolled 97 eyes of 59 patients that underwent femtosecond-assisted cataract surgery with AcrySof IQ Vivity intraocular lens implantation. Thirty subjects (60 eyes) were eligible for analysis. After 3 months, postoperative achieved binocular uncorrected visual acuity was -0.03 ± 0.06 logarithm of the minimum angle of resolution for distance, 0.06 ± 0.06 logarithm of the minimum angle of resolution for intermediate, and 0.19 ± 0.03 logarithm of the minimum angle of resolution for near. Defocus curve showed a smooth profile with no abrupt decrease of visual acuity. Minimonovision significantly improved visual acuity compared to when minimonovision was neutralized, for values of defocus curves from -1 to -3 D (p < 0.05). Twenty-six (87%) patients reported complete spectacle independence. High levels of satisfaction for distance and near vision resulted at VFQ-25 questionnaire. Only two patients complained of halos (6.7%) and one of them also of glare (3.3%). CONCLUSIONS: Implantation of this new non-diffractive extended depth-of-focus intraocular lens with minimonovision resulted in satisfying far, intermediate, and near visual acuity with a consistent reduction of spectacle dependence and improvement in patient's quality of life.

Effectiveness of oral probiotics supplementation in the treatment of adult small chalazion.

AIM: To define the possible beneficial impact of probiotics oral supplementation on patients affected by chalazion. METHODS: Prospective comparative pilot study on 20 adults suffering from chalazion randomly divided into two groups. The first group (n=10) received conservative treatment with lid hygiene, warm compression, and dexamethasone/tobramycin ointment for at least 20d. The second group (n=10), in addition to the conservative treatment, received a mixture of probiotic microorganisms of Streptococcus thermophilus ST10 (DSM 25246), Lactococcus lactis LLC02 (DSM 29536) and Lactobacillus delbrueckii (DSM 16606) once a day up to 3mo. Chalazia were classified according to their size into three groups: small (<2 mm), medium (≥2 to <4 mm), or large (≥4 mm). When conservative treatment with and without probiotics supplementation failed to resolve the lesion, invasive methods were used, intralesional steroid injection in medium size chalazion and surgical incision and curettage for the largest ones. RESULTS: Medical treatment with or without probiotics supplementation was effective only on the small size chalazia. There was a significant difference in the time taken for complete resolution of small size chalazia between the two groups in favor of the patients receiving probiotics (38.50±9.04d vs 21.00±7.00d, P=0.039). Medium and large size chalazia did not respond to medical treatment with or without probiotics supplementation over the follow-up period (3mo). The treatment did not induce any complications in both groups and no recurrence of chalaziosis was recorded in both groups. CONCLUSION: The considerable difference in time taken for complete resolution of small chalazia between the two groups in favor of the experimental one confirms the presence of a gut-eye axis.

Topographic Outcomes in Keratoconus Surgery: Epi-on versus Epi-off Iontophoresis Corneal Collagen Cross-Linking.

Background: Corneal collagen cross-linking (CXL) has become the gold standard for mild and moderate stages to stop the progression of keratoconus. We analyzed some corneal topography indices to compare iontophoresis epi-on and iontophoresis epi-off techniques throughout a two-year follow-up. Methods: A total of 64 eyes of 49 patients who underwent CXL were recruited. In 30 eyes the epi-off technique was performed, whereas the remaining 34 eyes were treated with the epi-on technique. All patients underwent a complete ophthalmologic examination that included CDVA, central and thinnest corneal thickness, Schirmer test I, TBUT test, and the Ocular Surface Disease Index. Results: In both groups, a significant improvement in visual function was recorded. No statistically significant differences between Kmax, Mean K, Flat K, Steep K values were found. Statistically significant differences (p < 0.05) between the epi-on and epi-off groups' pachymetry before and after 24 months follow-up as well as between the epi-on and epi-off groups' topographically thinnest point in the immediate post-surgery and 24 months after surgery were recorded. Conclusion: Our study highlighted that both techniques are valid in mid-term corneal stabilization. The advantage of the new iontophoresis epi-off cross-linking technique could be found in a faster imbibing time of the cornea, therefore reducing surgical times, with a lower risk of complications.

Unintentional Retinal Displacement in Eyes Treated for Rhegmatogenous Retinal Detachment Complicated by Proliferative Vitreoretinopathy with Pars Plana Vitrectomy and Silicone Oil.

PURPOSE: To examine the clinical characteristics, outcomes, and rate of unintentional displacement in eyes treated for rhegmatogenous retinal detachment (RRD) with pars plana vitrectomy (PPV) and silicone oil (SO). METHODS: This retrospective observational study examined 50 eyes of 50 patients who underwent surgical repair for primary RRD complicated by proliferative vitreoretinopathy (PVR) by PPV and 1000-centistoke SO injection at a single institutional centre. The patients assumed a face-down posture immediately after surgery. Blue-fundus autofluorescence (B-FAF) pictures were obtained at 1 month after surgical procedures using a Spectralis HRA + OCT (Heidelberg Engineering, Heidelberg, Germany). RESULTS: The primary success rate was obtained in 44 eyes (88%), on which the final analysis was conducted. Preoperative PVR was grade A in 7 eyes (15.9%), grade B in 28 eyes (63.6%), and grade C in 9 eyes (20.5%). The fovea was off and the detachment involved both the superior and inferior hemispheres of the retina in all cases. Breaks were located in the upper quadrants in 19 eyes (43.2%), in the lower quadrants in 12 eyes (27.3%), and in both upper and lower quadrants in 13 eyes (29.5%). The mean number of breaks was 3.4 ± 1.9. Intraoperative PFCL was used in 30 eyes (68.2%). Peeling of the epiretinal membrane/internal limiting membrane in the macula area was performed in 13 eyes (29.5%) during the first operation and carried out in all other eyes in occasion of SO removal. Preoperative BCVA was 2.1 ± 1.0 logMAR and improved to 0.8 ± 0.7 logMAR at the last follow-up (P < 0.0001). An upward unintentional retinal displacement was observed in 2 cases (4.5%). CONCLUSION: PPV and SO tamponade for complicated RRD are associated with good anatomical and functional outcomes and a very low rate of unintentional retinal displacement. Of the factors potentially implicated in favouring displacement that were studied, none were found significant.

Probiotic Supplementation Improved Acute Anterior Uveitis of 3-Year Duration: A Case Report.

BACKGROUND Uveitis is a clinical condition characterized by acute blurry vision related to an inflammation of the uvea. Gut microbiome dysbiosis can influence the prognosis of uveitis by inducing a loss of intestinal immune homeostasis leading to a lower activation threshold of the immune cells. This promotes a pro-inflammatory response resulting in reactivation of the disease. This is the case report of a 21-year-old woman with a 3-year history of acute anterior uveitis (AAU) of the right eye, who responded favorably to probiotic dietary supplementation. CASE REPORT A 21-year-old woman, previously unknown to our Ophthalmology Unit, presented with ocular pain and redness. Three years ago, she had been diagnosed with monolateral AAU in the right eye. Her medical and family histories were unremarkable. After a complete clinical evaluation, we decided to start a combination treatment protocol with continuous use of probiotics and the use of ocular steroids only during an exacerbation of the condition. To monitor the trend of the disease, she underwent a monthly clinical examination for the following year. During this period, we observed a decrease in ocular inflammation with a gain in the primary outcome (best-corrected visual acuity), and the steroids and atropine were discontinued for the following months. CONCLUSIONS This case report describes a patient with a 3-year history of AAU, who responded well to a combination treatment of dietary probiotic supplementation and steroids, demonstrating that probiotics can reduce recurrences of AAU.

Influence of gut microbiota on eye diseases: an overview.

The microbiota is a dynamic ecosystem that plays a major role in the host health. Numerous studies have reported that alterations in the intestinal microbiota (dysbiosis) may contribute to the pathogenesis of various common diseases such as diabetes, neuropsychiatric diseases, and cancer. However, emerging findings also suggest the existence of a gut-eye axis, wherein gut dysbiosis may be a crucial factor influencing the onset and progression of multiple ocular diseases, including uveitis, dry eye, macular degeneration, and glaucoma. Currently, supplementation with pre- and probiotics appears is the most feasible and cost-effective approach to restore the gut microbiota to a eubiotic state and prevent eye pathologies. In this review, we discuss the current knowledge on how gut microbiota may be linked to the pathogenesis of common eye diseases, providing therapeutic perspectives for future translational investigations within this promising research field.

Supporting IOL'S in a Deficient Capsular Environment: The Tale of No "Tails".

PURPOSE: To evaluate the efficacy and safety of the following three distinct surgical procedures for secondary IOL implantation without capsular support: Iris-claw lens, flanged transscleral fixated IOLs (Yamane technique), and sutureless transscleral hook IOL fixation (Carlevale IOL). MATERIALS AND METHODS: In this retrospective comparative study, three different sutureless IOL implantation techniques were compared in patients without any capsular support. Visual acuity and outcomes were analyzed in 24 eyes of 23 patients (14 male and 9 female). Study included 13 iris-claw lenses (Artisan Ophtec), 6 flanged transscleral fixated IOLs (Yamane technique using a MA60MA Alcon Inc IOL), and 5 transscleral Carlevale IOLS (Carlevale IOL, Soleko, Italy). RESULTS: logMAR mean best-corrected visual acuity (BCVA) improved from 0.49 ± 0.19 to 0.19 ± 0.10 at three months after surgery (p < 0.05). Postoperative BCVA was similar in all three groups, and no intergroup difference was noted. Three eyes (12.5%) had a raised IOP >25 mmHg, 2 eyes (8%) presented a subluxated/dislocated IOL, 4 eyes (16%) had corneal edema longer than 7 days, 3 eyes (12.5%) had irregular pupil profile, 2 eyes (8%) had vitreous hemorrhage, 7 eyes had (29%) corneal astigmatism over 3 diopters, and one patient (4%) developed cystoid macular edema (CME). CONCLUSIONS: All three surgical procedures can be considered adequate to correct aphakia in patients without capsular support with significant improvement in visual acuity and low complication.

Multimodal Imaging of Lamellar Macular Holes.

Evolution of imaging techniques has renewed interest in the diagnosis of lamellar macular hole (LMH) and greatly implemented the possibilities of gaining more detailed insights into its pathogenesis. Among noninvasive techniques, optical coherence tomography (OCT) is considered the primary examination modality to study LMHs, given its ability to image foveal structure and its widespread availability. OCT also allows to resolve the epiretinal materials associated with LMH, i.e., tractional epiretinal membranes (ERMs) and epiretinal proliferation (EP). En face OCT reconstructions are useful to confirm the foveal abnormalities shown by the eyes with LMH, whereas OCT angiography may reveal alterations of the size and shape of the foveal avascular zone and alterations of the density of the superficial and deep vascular plexuses. On slit-lamp biomicroscopy or fundus camera examination, LMH appears as a round or oval, reddish lesion at the center of the macula, slightly darker than the surrounding retina. The associated tractional ERM, causing wrinkling and glistening of the retinal surface, is usually readily appreciable, whereas EP is hardly apparent on biomicroscopy or fundus photography since the retina surface appears smooth. When imaged with blue fundus autofluorescence (B-FAF) imaging, LMHs are characterized by an increased autofluorescent signal, the intensity of which does not correlate with the thickness of the residual outer retinal tissue. Green reflectance and blue reflectance (BR) images clearly show the increased reflection and wrinkling of the retinal surface caused by tractional ERM associated with LMH. BR and multicolor imaging enable the visualization of EP associated with LMH in the form of a sharply demarcated dark area and in the form of a yellowish area surrounding the hole, respectively. Scarce data regarding invasive imaging techniques, such as fluorescein angiography, for the study of LMH are available in the literature. The aim of this review is to evaluate the contribution that each imaging modality can provide to study the morphologic characteristics of LMH.

Choriocapillary vascular density in central serous chorioretinopathy complicated by choroidal neovascularization.

BACKGROUND: To evaluate choriocapillary vascular density (CVD) in eyes with central serous chorioretinopathy (CSC) complicated by choroidal neovascularization (CNV), at baseline and after intravitreal injections (IVR) of Ranibizumab, using optical coherence tomography angiography (OCTA). METHODS: Twelve eyes of 12 patients were enrolled as group 1 and 12 unaffected fellow eyes formed group 2. Twelve eyes of 12 healthy controls were the control group. RESULTS: CVD in Group 1 did not differ before and after treatment. CVD of Group 1 was significantly lower compared with controls at baseline (whole, parafovea and fovea p < 0.05). CVD of controls resulted significantly higher than Group 2 at baseline (whole, parafovea and fovea p < 0.05). There were not significant differences in CVD between Groups 1 and 2 at baseline (p > 0.05). CONCLUSIONS: OCTA revealed a choriocapillary hypoperfusion that may be responsable for the beginning of this disease and the late development of CNV.

Prospective Study of Vessel Density by Optical Coherence Tomography Angiography After Intravitreal Bevacizumab in Exudative Age-Related Macular Degeneration.

INTRODUCTION: The aim of this study was to evaluate retinal and choriocapillaris (CC) vessel density, using optical coherence tomography angiography (OCTA), in the macular region at baseline and after three once-monthly intravitreal injections of bevacizumab (loading phase) in patients affected by exudative age-related macular degeneration (AMD). METHODS: A total 38 eyes of 38 patients with exudative AMD (16 women, 22 men; mean age 72.47 ± 7.46 years) were included in this study. We evaluated vessel density in different macular areas (whole image, fovea and parafovea) of the superficial capillary plexus (SCP), deep capillary plexus (DCP) and CC. In addition, central macular thickness (CMT) and choroidal thickness in the foveal region and 500 µm in the nasal and temporal directions were analyzed by enhanced depth image-OCT. RESULTS: There were no significant differences in vessel density in the SCP, DCP and CC after the loading phase compared to baseline (p > 0.05). In contrast, CMT (p = 0.039; 320.63 ± 175.05 vs. 372.47 ± 167.05 µm) and subfoveal choroidal thickness (SFCT) (p < 0.001; 189.21 ± 37.66 µm vs 170.37 ± 37.96 µm) significantly decreased after the loading phase compared to baseline. No significant correlations were found between SFCT and CC vessel density in the fovea, and between CMT and SCP and DCP (p > 0.05) at baseline and after the loading phase. Also, best corrected visual acuity did not correlate with CMT, SCP and DCP at baseline and after treatment (p > 0.05). CONCLUSION: Macular and choroidal thickness did not correlate with vessel density, but probably correlated to vascular exudation. The anti-VEGF treatment, acting on vascular hyperpermeability, determines the reduction of the retinal and choroidal exudation, resulting in a decrease of their thicknesses. Consequently, these parameters could reflect the effectiveness of the anti-VEGF injections for treating exudative AMD respect to OCTA parameters.

Twenty-Year Follow-Up of Excimer Laser Photorefractive Keratectomy: A Retrospective Observational Study.

INTRODUCTION: Photorefractive keratectomy (PRK) was introduced in the late 1980s to correct myopia. The purpose of this study was to assess its long-term efficacy and safety, analyzing patients with at least 20-year follow-up. METHODS: This retrospective observational study was carried out on 85 eyes of 54 patients (33 females) that underwent PRK between 1991 and 1998 (mean age 32.62 ± 9.74, range 18-55 years). Both preoperatively and postoperatively, patients underwent a complete ophthalmological evaluation, including uncorrected and corrected distance visual acuity, slit-lamp, intraocular pressure, dilated fundus, and corneal topographic examinations. The outcome assessment was made by comparing the preoperative refraction, as spherical equivalent, with the postoperative ones, taking into account the planned refractive correction. Safety and efficacy indices were also calculated. All the data were evaluated with a paired t test. RESULTS: The mean attempted correction as spherical equivalent was - 5.64 ± 3.01 D (range - 1.00 to - 15.00 D), while the mean achieved correction after 20 years was - 4.30 ± 3.13 D (range - 1.88 to - 14.25 D), with a significant statistical difference (p < 0.01). The mean expected refractive outcome was - 0.27 ± 0.81 D (range - 4.00 to + 1.25 D). The mean difference between achieved and attempted treatment was 1.33 ± 1.92 D (range - 4.25 to + 6.25 D), with a significant difference (p < 0.01). The safety index was 1.00 and the efficacy index was 0.63. CONCLUSION: The results provided by this study highlight that the procedure could be considered safe, with no long-term sight-threatening complications such as late ectasia or haze.

Orbital and Eyelid B-Cell Lymphoma: A Multicenter Retrospective Study.

BACKGROUND: The aim of this study was to analyze patients diagnosed, staged and treated for orbital and eyelid B-cell lymphoma (OEL). METHODS: One hundred and forty-one cases of OEL were included in this study. Primary endpoints were to analyze the histopathologic findings, the main risk factors and the type of treatment and to correlate them with recurrence of OEL. The secondary endpoint was to determine the progression-free survival (PFS) time. RESULTS: Extranodal marginal zone B-cell lymphoma was the most frequent subtype (66%), followed by small lymphocytic lymphoma (12.7%), diffuse large B-cell lymphoma (DLBCL) (9.2%), follicular lymphoma (6.6%), mantle cell lymphoma (4.3%) and Burkitt lymphoma (1.2%). The probability of relapse was influenced by the histopathologic subtype DLBCL (OR = 7.7, 95% CI 1.8-32.3) and treatment with chemotherapy (OR = 14.9, 95% CI 2.6-83.7). Multivariate analysis showed that the histopathologic subtype DLBCL and chemotherapy treatment retained statistical significance for a poorer PFS, with hazard ratios of 8.581 (p = 0.0112) and 9.239 (p = 0.0094), respectively. CONCLUSIONS: Five lymphoma subtypes were found in patients with OEL. The histopathologic subtype and the type of treatment were found to be the main factors influencing treatment outcome.

Evaluation of corneal structures in myopic eyes more than twenty-two years after photorefractive keratectomy.

The aim of this study is to evaluate corneal epithelial thickness (CET), corneal densitometry (CD) in 84 myopic eyes (57 patients) more than 22 years after photorefractive keratectomy, using anterior segment-optical coherence tomography (AS-OCT) and Scheimpflug imaging system. The CET was significantly higher in all operated eyes than in unoperated eyes in central sector. A statistically significant increase in CD in corneal anterior layer of central sector was shown in groups of operated eyes with greater ablation depth respect to unoperated eyes. While there was no significant difference in CD between the operated eyes groups with lower ablation depth and unoperated eyes. A significant trend toward higher values in anterior CD with deeper ablations in central sector was found. These noninvasive imaging techniques allow to better understand the corneal remodeling process after photoablation and to monitor the patients over time.

Methotrexate for the treatment of thyroid eye disease.

Background/Aim. To evaluate the efficacy of methotrexate for the treatment of thyroid eye disease (TED). Methods. 36 consecutive patients with active TED, previously treated with corticosteroids but stopped due to the occurrence of side effects, were commenced on methotrexate therapy. Two different weekly doses were administered depending on the weight of the patient (7.5 mg or 10 mg). Clinical activity score (7-CAS), visual acuity (VA), ocular motility, exophthalmos, and eyelid position were retrospectively evaluated at 3, 6, and 12 months and compared with baseline data. Results. There was a statistically significant improvement in 7-CAS at 3, 6, and 12 months after treatment (P < 0.0001). There was no significant change in visual acuity. Ocular motility disturbances improved at 6 and 12 months (P < 0.001). There was no significant change in exophthalmos (mean 24 mm, SD 3 mm) or eyelid position (marginal reflex distance mean 6 mm, SD 1.5 mm) during the follow-up period. No side effects were registered. Conclusions. Methotrexate therapy is effective in reducing CAS and ocular motility disturbances. No significant improvement in proptosis or eyelid retraction should be expected from this treatment. Eventually, it might be considered a suitable alternative treatment in TED for patients who cannot tolerate steroids.
