Acquired enophthalmos in idiopathic orbital inflammatory disease.

Purpose: To describe a rare case of acquired enophthalmos in a patient with idiopathic orbital inflammatory disease after treatment with systemic corticosteroids. Observations: Orbital socket contracture produces a non-traumatic enophthalmos and is most frequently reported as a consequence of orbital trauma or metastatic fibrosis. A previously healthy 64-year-old male presented with 3-month history of binocular diplopia and left proptosis, hypoglobus, supraduction deficit, and compressive neuropathy. Imaging techniques showed a left orbital mass; laboratory tests and biopsy of the mass lead to the diagnosis of idiopathic orbital inflammatory disease. Systemic corticosteroids were administered and, surprisingly, the patient developed left enophthalmos with eyelid retraction. Conclusions and Importance: Although extremely unusual, orbital socket contracture can cause enophthalmos and visual morbidity in patients with idiopathic orbital inflammatory disease treated with corticosteroids.

Presentation of Graves' orbitopathy within European Group On Graves' Orbitopathy (EUGOGO) centres from 2012 to 2019 (PREGO III).

BACKGROUND: Graves' orbitopathy (GO) is subject to epidemiological and care-related changes. Aim of the survey was to identify trends in presentation of GO to the European Group On Graves' Orbitopathy (EUGOGO) tertiary referral centres and initial management over time. METHODS: Prospective observational multicentre study. All new referrals with diagnosis of GO within September-December 2019 were included. Clinical and demographic characteristics, referral timelines and initial therapeutic decisions were recorded. Data were compared with a similar EUGOGO survey performed in 2012. RESULTS: Besides age (mean age: 50.5±13 years vs 47.7±14 years; p 0.007), demographic characteristics of 432 patients studied in 2019 were similar to those in 2012. In 2019, there was a decrease of severe cases (9.8% vs 14.9; p<0.001), but no significant change in proportion of active cases (41.3% vs 36.6%; p 0.217). After first diagnosis of GO, median referral time to an EUGOGO tertiary centre was shorter (2 (0-350) vs 6 (0-552) months; p<0.001) in 2019. At the time of first visit, more patients were already on antithyroid medications (80.2% vs 45.0%; p<0.001) or selenium (22.3% vs 3.0%; p<0.001). In 2019, the initial management plans for GO were similar to 2012, except for lid surgery (2.4% vs 13.9%; p<0.001) and prescription of selenium (28.5% vs 21.0%; p 0.027). CONCLUSION: GO patients are referred to tertiary EUGOGO centres in a less severe stage of the disease than before. We speculate that this might be linked to a broader awareness of the disease and faster and adequate delivered treatment.

Non-arteritic anterior ischemic optic neuropathy after uneventful delivery in a healthy woman.

INTRODUCTION: Non-arteritic anterior ischemic optic neuropathy (NAION) is the most common cause of optic nerve swelling and optic neuropathy in adults over 50 years of age. It has been rarely reported during pregnancy, mostly related to systemic and ocular predisposing conditions. CASE REPORT: We report the case of a 44 years-old healthy female with no previous remarkable clinical history. She had in vitro fertilisation treatment to get pregnant. 18 days after uneventful cesarean section she referred sudden painless vision loss in her right eye (RE), denser inferiorly, with concurrent optic disc edema and relative afferent pupillary defect. Steroid intravenous treatment during the acute episode showed no improvement. Our patient showed normal magnetic resonance imaging (MRI), blood test, autoimmune disease biomarkers, infectious serology and inflammatory markers. She was diagnosed of RE NAION. After one year follow-up visual field defect remains stable. CONCLUSION: As far as we know this is the first report of NAION after in vitro fertilisation, uneventful pregnancy and cesarean section showing no systemic or ocular risk factors other than a small cup to disc ratio. Hemodynamic and hormonal changes during late pregnancy and uneventful cesarean section can trigger an episode of NAION in a healthy young woman.

Influence of corneal biomechanical properties on intraocular pressure measurement in different types of Graves' orbitopathy

BACKGROUND/AIMS: To compare the ocular biomechanical properties of inactive Grave's orbitopathy (GO) patients and healthy subjects and to evaluate the influence of severity and phenotype of GO on these parameters. METHODS: This was a cross-sectional study. All included inactive GO patients and healthy controls underwent complete ocular examination, including Goldman applanation tonometry (GAT), corneal biomechanical analysis using Ocular Response Analyser (ORA), and corneal epithelial thickness analysis using Optovue. Patients with inactive GO were classified based on the severity and orbital phenotype (predominantly myogenic or lipogenic). Comparison among groups was performed. RESULTS: 60 eyes from 30 inactive GO patients and 30 healthy eyes were examined. Corneal hysteresis (CH) was significantly lower in inactive GO patients (9.6 [p25 8.1; p75 11.2]) compared to controls (10.4 [9.8; 11.5]) (p = 0.012). In GO patients, cornea compensated intraocular pressure (IOPcc) was significantly higher than Goldman applanation tonometry IOP (IOP-GAT) (p = 0.001). A total of 13.3% GO patients were initially classified as having ocular hypertension (OHT; defined as IOP > 21 mmHg with no signs of glaucomatous optic neuropathy) based on IOP-GAT measurement. According to IOPcc, 27.8% of GO patients were classified as OHT. In GO patients, no differences were found in corneal bimechanical properties according to the disease severity or orbital phenotype. CONCLUSIONS: CH is significantly lower in inactive GO patients compared to healthy subjects. ORA corrected IOP was significantly higher in GO patients compared to IOP-GAT. No differences in corneal biomechanical properties between mild and moderate-to-severe GO disease and between myogenic and lipogenic orbitopathy were found.

Posterior scleral perforation due to endogenous endophthalmitis in a pregnant with selective IgA deficiency.

We present the case of a 35-year-old female patient, pregnant in her third trimester, with no ophthalmologic history of interest and a medical history of IgA deficiency syndrome with bronchiectasis as the only symptomatology, who came to another center with clinical symptoms of ocular discomfort. She was initially diagnosed with anterior uveitis and treated with topical and periocular corticosteroids. Edema and palpebral erythema appeared a few days later and she was diagnosed with idiopathic orbital inflammation and was treated with intravenous (I.V.) corticosteroids, which led to the appearance of a purulent palpebral and subconjunctival collection with a diagnosis of orbital cellulitis. At this time, she came to our center, where ultrasound and magnetic resonance imaging (MRI) showed intraocular and scleral destructuring with scleral perforation. The subconjunctival abscess was drained, being positive for pseudomonas aeruginosa, and sputum culture was positive for Pseudomonas aeruginosa, so she was diagnosed with endogenous endophthalmitis due to transient Pseudomonas aeruginosa bacteremia in the context of IgA deficiency syndrome and treated with antibiotherapy. Despite the improvement of the infectious clinic, the persistence of positive cultures for pseudomonas aeruginosa and the evolution to phthisis bulbi at 2 months led to definitive treatment with evisceration. To our knowledge, this is the first reported case of endogenous endophthalmitis associated with IgA deficiency and the first reported case of endogenous bacterial endophthalmitis caused by pseudomonas aeruginosa during pregnancy.

Does hyaluronidase injected in periocular area change skin ultrastructure?: Standardized in vitro analysis.

BACKGROUND: Treatment with hyaluronic acid (HA) fillers as a strategy for rejuvenation has experienced a significant growth in recent years, accompanied by a parallel increase in its complications, the treatment of which, such as hyaluronidase, we must be aware of. PATIENTS/METHODS: 14 patients (28 eyes) had indication for upper blepharoplasty surgery in the Hospital Universitario y Politécnico La Fe. After surgery, periocular skin of one eye of each patient was infiltrated with 300 U of hyaluronidase (14 cases) while the skin of the fellow eye was preserved untreated (14 controls). All samples were studied by the Pathology department, and finally, 6 variables (skin structure alteration, degeneration of elastic fibers, deposits, collagen fibers destructuring, inflammation, and other findings) were analyzed. RESULTS: No differences in skin structure, elastic fibers, and collagen dermal fibers were found between hyaluronidase-treated skin and controls. A significant association between ex vivo application of hyaluronidase in periocular skin and the presence of amorphous extracellular deposits within the dermis was found. CONCLUSIONS: Hyaluronidase applied ex vivo to periocular skin led to presence of deposits within the extracellular matrix compared to control eyelid skin but elastin and collagen dermis structure remained unaltered.

Teaching and Evaluation Methods of the Use of the Tourniquet in Severe Limb Bleeding among Health Care Professionals: A Systematic Review.

INTRODUCTION AND OBJECTIVES: Massive hemorrhage (MH) is a growing pathology in military settings and increasingly in civilian settings; it is now considered a public health problem in the United States with large-scale programs. Tourniquets are the fastest and most effective intervention in MH if direct pressure is not effective.The Liaison Committee on Resuscitation (ILCOR) recognizes a knowledge gap in optimal education techniques for first aid providers. This review aims to describe training and evaluation methods for teaching tourniquet use to both health care and military professionals. METHODS: The MEDLINE, CINAHL, WEB of Science, and Scopus databases were reviewed (from 2010 through April 2020). The quality of the selected studies was assessed using the Consolidated Standards of Reporting Trials (CONSORT) scale. Studies that met at least 65% of the included items were included. Data were extracted independently by two reviewers. RESULTS: Ten of the 172 articles found were selected, of which three were randomized clinical trials. Heterogeneity was observed in the design of the studies and in the training and evaluative methods that limit the comparison between studies. CONCLUSIONS: The results suggest that the training strategies studied are effective in improving knowledge, attitudes, and practical skills. There is no universal method, learning is meaningful but research should be directed to find out which ones work best.

Maternal and fetal outcomes during pregnancy and puerperium in obese and overweight pregnant women. A cohort study.

PURPOSE: compare incidences of maternal-fetal complications during pregnancy, labor, and early puerperium according to baseline BMI in a consecutive cohort of pregnant women. METHODS: This retrospective cohort study compares pregnancy outcome indicators by body mass index (BMI) in 1236 pregnant women managed over the period January 2017 to May 2018. Data were collected regarding the personal history (smoking, diabetes and hypertension), obstetrics and BMI (kg/m2) (normoweight 18.5-24.9, overweight 25-29.9, obese ≥ 30). RESULTS: Of the 1236 women, 354 (28.6%) were overweight and 206 (16.7%) were obese at the start of pregnancy follow-up. Mean age at this time was 33 years (SD 6). Risk factors for a cesarean-section delivery assessed through logistic regression were maternal age (OR 1.05 95% CI 2.06-6.15; p < 0.001) and previous C-section (OR 4.21 95% CI 2.89-6.14; p < 0.001) regardless of BMI. In a propensity score analysis, pregnancy weight gain was found lower in obese vs normoweight (- 2.73 kg 95% CI - 3.74 to - 1.72 p < 0.001), and newborn weight higher in obese vs normoweight women (161.21 g 95% CI 57.94-264.48 p = 0.002). Labor duration and weight gain were reduced in overweight vs normoweight subjects (- 0.72 h 95% CI - 1.27 to - 0.17 p = 0.010 and 0.81 kg 95% CI - 1.50 to - 0.12 p = 0.021, respectively). CONCLUSIONS: In this cohort, obese women showed higher rates of prenatal complications yet obesity and overweight were not related to worse puerperium outcomes.

Prospective pilot study comparing deep sclerectomy outcomes with a long-term and intense corticosteroid treatment versus a standard one.

OBJECTIVE: To compare prospectively intraocular pressure (IOP) results after deep sclerectomy (DS) using a topical short-term corticosteroid treatment (STCT, 1 month) versus a topical long-term and intense corticosteroid treatment (LTCT, 6 months) in a two2 year-follow-up. METHODS: Patients with medically uncontrolled open angle glaucoma were prospectively recruited and underwent a DS. RESULTS: We operated 45 eyes of 45 patients, 22 in STCT group and 23 in LTCT group. Median preoperative IOP was 27 (22-36.75) mm Hg for STCT and for 25 (22-28) mm Hg for LTCT group without significant difference (p=0.195). Median postoperative IOP was 4 (3-6.25) mm Hg in STCT group versus 2 (0-5) mm Hg in LTCT at day 1 (p=0.003); 8.5 (5.75-11.25) mm Hg (STCT) vs 6 (4-9) mm Hg (LTCT) at week 1 (p=0.079); 17.5 (14.75-22.25) mm Hg (STCT) vs 13 (10-14) mm Hg (LTCT) at month 1 (p=0.001); 16 (12-20) mm Hg (STCT) vs 12 (10-15) mm Hg (LTCT) at month 3 (p=0.008); 17 (14-20) mm Hg (STCT) vs 12 (10-14) mm Hg (LTCT) at month 6 (p=0.000); 16 (14-20) mm Hg (STCT) vs 14 (10-16) mm Hg (LTCT) at year 1 (p=0.002) and 17.5 (15-19) mm Hg (STCT) vs 14 (12-16) mm Hg (LTCT) at year 2 (p=0.001). The complete success rate was 54.5 % in STCT and 87 % in LTCT (p=0.018). CONCLUSIONS: A long-term and intensive postoperative treatment enhances success rate in DS compared with a standard protocol.

Relationship between corneal hysteresis and lamina cribrosa displacement after medical reduction of intraocular pressure.

PURPOSE: To evaluate the relationship between the displacement of the lamina cribrosa (LC) and prelaminar tissue with corneal hysteresis (CH) using spectral-domain coherence tomography (SD-OCT) after reducing intraocular pressure (IOP) with medical treatment. METHODS: Sixty-one eyes of 61 patients with ocular hypertension or primary open-angle glaucoma who were going to start with treatment were imaged by means of 12 cross-sectional scans of the optic nerve using enhanced depth imaging SD-OCT before and after 1 week of treatment. We used the 'follow-up' mode to make sure that all the measurements were performed in the same location. We also measured the CH using an Ocular Response Analyzer, and we related it to the magnitude of displacement of LC and prelaminar tissue and the thickness of both structures. RESULTS: There was a significant variation of LC thickness from 132.66±37.40 to 160.09±41.13 µm (p<0001). LC distance was significantly reduced from 258.53±145 µm before treatment to 239.86±135 µm after it. No significant changes were found in the thickness and movement of prelaminar tissue before and after treatment. The only factors related with LC displacement were CH (R2=0.48) and age (R2=0.42). CONCLUSIONS: A significant increase in LC thickness and a reduction in the posterior displacement of LC but not in the prelaminar tissue were demonstrated after IOP reduction with medical treatment. The factors most related with LC displacement were age and CH.

Sutureless artificial iris after phacoemulsification in congenital aniridia.

PURPOSE: This article reports the first case of a sutureless artificial iris prosthesis used in combination with cataract surgery for congenital aniridia with successful visual and cosmetic results. CASE REPORT: A 15-year-old woman with congenital bilateral partial aniridia, cataracts, and intense photophobia presented to the Cornea and Refractive Surgery Unit of the Ophthalmology Department. She was managed with an artificial iris implant (ArtificialIris, Dr. Schmidt Intraocularlinsen GmbH, Human Optics) fixed in the ciliary sulcus without any sutures after small-incision cataract surgery. At the 1-year follow-up, subjective complaints of glare and photophobia as well as binocular near visual acuity improved significantly. The cosmetic result was excellent. No postoperative complications have been recorded within this period. CONCLUSIONS: The ArtificialIris is a promising device for treating photophobia in congenital aniridia. ArtificialIris does not require suture fixation with adequate capsular support and iris remnants.

Visual and anatomical outcomes of non-arteritic anterior ischemic optic neuropathy with high-dose systemic corticosteroids.

BACKGROUND: To evaluate the visual and anatomic outcomes after systemic steroid treatment in non-arteritic anterior ischemic optic neuropathy (NAION). METHODS: Ten eyes from ten patients diagnosed with NAION and treated during the acute phase with 80 mg daily, tapering-down dose of corticosteroids were compared with a non-contemporary cohort of 27 patients that received no treatment. The visual outcomes of treated and untreated group were compared. Patients underwent complete ophthalmic examination including determination of Snellen visual acuity (VA), visual fields (VFs) (standard automated perimetry, Swedish Interactive Testing Algorithm 24-2 strategy), and optical coherence tomography (OCT) scanning of the optic nerve head at diagnosis, 6-8 weeks and 6 months after presentation. RESULTS: No statistical differences were found between steroid-treated and untreated NAION for the median change in VA (Mann-Whitney P = 0.28), median change in VF mean deviation (MD) and median change in VF pattern standard deviation (PSD) (Mann-Whitney P = 0.213 and P = 0.07 respectively). Statistical analysis showed no differences when comparing average RNFL loss (P = 0.871) and RNFL loss for superior, nasal, inferior and temporal optic disc quadrants between both groups. Complications occurred in three of the ten treated patients (30%); in one of them, steroid therapy had to be discontinued. Another two patients developed a NAION in their fellow eye after 2 and 3 months while on low-dose prednisone. No complications developed in the control group. The study was interrupted early due to a significantly higher rate of complications observed in the treated group (P = 0.002) CONCLUSION: High-dose systemic steroid treatment did not show any beneficial effect in visual and anatomic outcomes when given during the acute phase of NAION. Furthermore, it caused serious complications in a third of the patients treated.

Persistent subretinal fluid due to central serous chorioretinopathy after retinal detachment surgery.

BACKGROUND: The causes of persistent submacular detachment after successful rhegmatogenous retinal detachment (RRD) surgery remain unknown. Its presence is associated with poor postoperative visual acuity, but due to its spontaneous resolution no additional therapeutic or diagnostic procedure is recommended. CASE REPORT: A case of central serous chorioretinopathy (CSC) that simulated persistent subfoveal fluid after RRD surgery is presented. CONCLUSION: To the authors' knowledge, no other case of visual impairment after successful retinal detachment surgery due to CSC has been reported in the PubMed database. In view of this report, CSC should be considered in the differential diagnosis of persistent subretinal fluid after successful retinal detachment surgery.

Retrobulbar ocular blood flow changes after orbital decompression in Graves' ophthalmopathy measured by color Doppler imaging.

PURPOSE: To evaluate if decompression surgery produces changes in retrobulbar blood flow parameters in Graves' ophthalmopathy (GO). METHODS: Retrobulbar blood vessels of 26 eyes (14 patients) that underwent orbital bone decompression between June 2009 and May 2010 were measured prospectively using color Doppler ultrasound before and after surgery. The disease was inactive in all patients enrolled according to the European Group on Graves' Orbitopathy. Patients were classified with mild, moderate-to-severe, or sight-threatening disease. All patients underwent a full ophthalmic examination including intraocular pressure and Hertel measurement. An age-matched control group included 20 eyes of 20 healthy volunteers. RESULTS: The resistance indexes (RIs) in the central retinal artery (CRA) and ophthalmic artery (OA) were significantly higher in patients with GO preoperatively than in the control group (P < 0.001, P = 0.001 respectively). After decompression surgery, a significant decrease in RIs occurred in the CRA (5%) and OA (6%) (P = 0.002, P < 0.001 respectively). Proptosis was decreased a median of 6 mm (range, 4-7). Three-wall decompression surgery resulted in a significantly greater reduction in exophthalmos (median 7 mm) compared with two-wall surgery (median 5 mm) and one-wall surgery (2.5 mm). Although no significant correlation was found, the RIs decreased more with major reductions in exophthalmos. CONCLUSIONS: In inactive moderate-to-severe GO, the RIs of the CRA and OA are higher than in normal subjects. The authors hypothesized that increased RIs of inactive GO may be due to orbital extrinsic compression of vascular structures because decompression surgery leads to decreases in the RIs of both the CRA and OA.

Role of trichloroacetic acid in treating posterior conjunctival cyst in an anopthalmic socket.

Orbital cysts in anophthalmic socket are infrequent. Most of the cysts reported are anterior and the inability to retain a formerly well-fitted prosthesis is the most common symptom. We present a posterior conjunctival cyst developed after a dermo-fat graft reconstruction in an eviscerated socket. Eleven years after evisceration surgery due to irreparable ocular trauma an extrusion of the orbital implant occurred. Removal of the orbital implant and a socket reconstruction with dermis fat graft was done. Three years later, the patient again returned back to the treating ophthalmologist with complaint of an inability to retain the formerly well-fitted artificial prosthesis. A detailed ophthalmic examination failed to reveal any abnormality. The CT scan showed a posteriorly located conjunctival cyst in the right orbit. Tricholoroacetic acid (TCA) was injected intracystically into the conjunctival cyst. Ten months of follow-up did not show any recurrence of the conjunctival cyst and allowed complete tolerance of the prosthesis. This case report highlights the role of tricholoacetic acid in treating a posteriorly located conjunctival cyst in an anophthalmic socket.
