Effect of Compression Dressing After Upper Eyelid Blepharoplasty on Edema, Ecchymosis, Pain and Ocular Surface Irritation.

PURPOSE: To investigate the effect of a compression dressing (CD) on edema, ecchymosis, aesthetic outcome, pain, and ocular surface irritation after upper eyelid blepharoplasty. METHODS: We conducted a case-control study. Bilateral blepharoplasty was performed on both upper eyelids at the same time in patients with dermatochalasis. One side was randomized for CD. Edema and ecchymosis were scored at a 4-point rating scale by a blinded observer 1 day (D1), 1 week (D7), and 8 weeks (D56) after surgery; the same for scar formation regarding redness and bulging at D7 and D56. Aesthetic outcome was evaluated by the patient and blinded observer using the global aesthetic improvement score at D1, D7, and D56. Postoperative pain was scored by the patients using a visual analogue scale (0 to 10) at D1. At D1 patients had to state which side they felt more comfortable. RESULTS: Edema, scar formation and aesthetic outcome evaluated by the patient and blinded observer did not differ between the 2 sides on any of the survey days (p > 0.05). The median degree of ecchymosis was slightly higher on the lids without CD at D1 (1 [0-2] vs. 1.5 [0-2]; p = 0.495) and D7 (0 [0-2] vs. 0.5 [0-2]; p = 0.183), but not statistically significant. Postoperative pain was similar regardless to the use of CD (p = 0.925). The majority (55%) found the side without CD more comfortable. There was no case of corneal erosion and corneal staining was similar in both groups (p > 0.05). CONCLUSIONS: Using a CD after blepharoplasty shows no advantages regarding postoperative edema, ecchymosis, scar formation, or aesthetic results in the early postoperative period. As most patients preferred the noncovered side, CD can be omitted after blepharoplasty without inferiority for the postoperative results. CLINICAL TRIAL REGISTRY: NCT06111170.

Observation of Unexplained Cases of Unilateral Upper Eyelid Retraction from Idiopathic Inflammation or an Atypical Form of Graves' Orbitopathy.

BACKGROUND: We observed cases of unilateral upper eyelid retraction (UER) with unclear pathogenesis, where a definitive diagnosis of Graves' orbitopathy (GO) could not be made and other pathologies were ruled out. The aim is to present patients' findings, discuss possible underlying mechanisms, and to describe diagnostic testing and therapeutic approaches. PATIENTS AND METHODS: Patients were retrospectively analyzed who presented to the Department of Ophthalmology of LMU Munich between 2016 and 2021 without a definitive diagnosis of GO or other pathological causes. RESULTS: Thirteen patients with unexplained UER were included; all showed thickening of the levator complex in imaging. When biopsy was performed, no malignancy could be detected. Therapeutic strategies included oral steroids and surgical upper eyelid blepharotomy. CONCLUSION: As regards to pathogenesis, in 7/13 patients, a condition of idiopathic UER due to an idiopathic inflammatory response can be postulated rather than a variant of GO.

Current Practice in the Treatment of Epithelial and Melanocytic Tumours with Interferon-α2b: A Survey of Tertiary Eye Centres in Germany.

PURPOSE: To evaluate the standard of care, in particular the use of topical or subconjunctival interferon-α2b, in treating ocular surface squamous neoplasia or melanocytic tumours in tertiary eye centres in Germany. METHODS: A survey containing 14 questions was sent to 43 tertiary eye centres in Germany. The questions addressed the surgical and medical management of ocular surface squamous neoplasia and melanocytic tumours (primary acquired melanosis and malignant melanoma), as well as the clinical experiences and difficulties in prescribing off-label interferon-α2b eye drops and subconjunctival injections. RESULTS: Twenty-four tertiary eye centres responded to the survey. Eighty-three percent of centres had used interferon-α2b in their clinical practice and 25% prescribed it as the first-line cytostatic agent following surgical excision of ocular surface squamous neoplasia, while 10% would do so for melanocytic tumours. Correspondingly, the majority of respondents selected mitomycin C as their first-line agent. Side effects were uncommon with topical interferon-α2b eye drops but were more frequently reported after subconjunctival interferon-α2b injections. In total, eight centres had experience with interferon-α2b injections. The most significant obstacles perceived by ophthalmologists when prescribing interferon-α2b were its high cost and the reimbursement thereof. CONCLUSION: Off-label mitomycin C was the preferred adjuvant therapy for epithelial and melanocytic tumours, with interferon-α2b being the standard second-line option. Interferon-α2b has predominantly been used to treat ocular surface squamous neoplasia and, to a lesser extent, melanocytic tumours at German tertiary eye centres. Following its market withdrawal, supply shortages of interferon-α2b are likely to have a profound impact on patient care and their quality of life.

Evaluation of visual evoked potentials in dysthyroid optic neuropathy.

PURPOSE: To evaluate the findings of visual evoked potentials (VEP) in patients with dysthyroid optic neuropathy (DON). METHODS: In this observational, cross-sectional study 40 eyes (22 patients) with a diagnosis of DON were included. RESULTS: We discovered that in 16 out of 37 eyes with pattern-VEP (p-VEP), the latency of P100 wave was normal in spite of having a diagnosis of DON. The same pattern was also observed in the measurement of the amplitude of P100 wave: in 28 out of 37 eyes with p-VEP the amplitudes were observed as normal. In 3 eyes of 3 patients p-VEP showed no response, therefore a flash-VEP (f-VEP) was performed. Flash-VEPs of those patients indicated a prolonged P100 latency with a reduced amplitude. The sensitivity of abnormal P100 latency was 56.8% (95%CI 39.5-72.9%); and that of reduced P100 amplitude was 24.3% (95%CI 11.8-41.2%). Also, in 40 eyes color vision test by Arden was performed. In 36 eyes (20 patients) the tritan value was pathological (based on a threshold of ≥8%). CONCLUSION: According our data, VEP seems to have a limited potential especially in patients with a good best-corrected visual acuity (BCVA ≤0.2 LogMAR) for identifying the optic nerve involvement. The fact that P100 latency and amplitude were normal even in cases with an optic nerve swelling makes us question the usefulness of the VEP for diagnosing cases of DON in daily clinical life.

A prospective randomized pilot study evaluating the scar outcome after gluteal dermis fat graft with and without kinesiotaping.

PURPOSE: To compare gluteal wound healing after dermis fat graft (DFG) implantation in patients with and without local application of kinesiotapes. METHODS: In this prospective, single-center analysis, 16 patients who underwent DFG implantation were randomized in two groups. Wound healing was compared 4-6 weeks after therapy and 3 months later (after application of 2 cycles of kinesiotaping for 2-3 weeks in the case and no specific therapy in the control group). Demographic data, patient content and wound healing were assessed. Scarring was graded (0-3) by evaluation of photodocumentation by 2 blinded, independent observers. RESULTS: Mean scar grading by both observers decreased from 2.31 ± 0.48 to 1.13 ± 0.72 in the case and from 2.38 ± 0.52 to 1.44 ± 0.50 in the control group with interobserver agreement on scar grading being substantial to almost perfect in both groups. Scar length decreased significantly in both groups (p = 0.008). Scar prominence decreased in 2/3 of cases in the case and 1/3 in the control group. Scar coloring significantly improved in the case group alone (p = 0.031). CONCLUSION: No functionally impairing or painful scar developed. No adverse effects occurred after kinesiotaping. Gluteal scars shortened significantly over time and were significantly paler in the case group. Kinesiotaping may improve scar elevation over no specific scar therapy.

A pathological indicator for dysthyroid optic neuropathy: tritan color vision deficiency.

PURPOSE: To investigate the sensitivity of the color vision test by Arden in patients with dysthyroid optic neuropathy (DON) to improve diagnosis. METHODS: In this observational, retrospective study, we included the medical records of 92 eyes (48 patients) with diagnosis of DON between 2008 and 2019 in order to evaluate the full spectrum of findings from the color vision test by Arden, and to determine potential importance of this test. Thirty-five patients were female, and 13 patients were male. The mean age was 58.0 years (range: 34-79) at the time of the DON diagnosis. RESULTS: Forty-one eyes displayed relatively good BCVA with ≤ 0.2 LogMAR. We found a protan value exceeding the threshold of ≥ 8% in 57 eyes (30 patients) at the time of the diagnosis. The sensitivity of protan was 61.9% (95% CI 51.2-71.8%), while that of tritan was a striking 98.9% (95% CI 94.1-99.9%). We discovered one pathological sign, tritan deficiency (based on a threshold of ≥ 8%) consistently in all eyes but one at the time of the diagnosis, regardless of the visual field defects or any changes in best-corrected visual acuity (BCVA). CONCLUSION: We found blue-yellow (tritan) deficiency, to be a sensitive and reliable indicator of dysthyroid optic neuropathy. We conclude that, in cases with suspected DON, a color vision test that can detect tritan deficiency is an essential tool for the adequate assessment, diagnosis, and treatment of DON.

Eyelid Surgery in Graves' Orbitopathy. / Lidoperationen bei endokriner Orbitopathie.

Patients with Graves' orbitopathy often develop eyelid changes. These may be the result of a volume effect or a malposition. Both dermatochalasis with fat tissue increase and eyelid retraction may lead to functional or aesthetic impairment. The present article reviews indications, timing and principles for corrective eyelid surgery. If at all possible, surgical eyelid correction in Graves' orbitopathy should be performed once the disease became inactive and stabile. Surgical details of eyelid lengthening procedures for upper and lower eyelid retraction are presented. Meanwhile anterior blepharotomy became the primary procedure for upper eyelid lengthening. However, there is no such standard procedure for lower eyelid lengthening, although it is recommended to use a spacer. For blepharoplasty it is mandatory to distinguish between orbital fat prolapse and subbrow fat pad. A prolapse of the lacrimal gland should not be missed and generally, skin excision performed sparingly.

Comparison of different devices to measure the intraocular pressure in thyroid-associated orbitopathy.

PURPOSE: To evaluate the correlation of the intraocular pressure measurements (IOP) with non-contact tonometer Corvis Scheimpflug technology (Corvis ST), Goldmann applanation tonometry (GAT), ocular response analyzer (ORA), and iCARE rebound tonometer in patients with thyroid-associated orbitopathy (TAO) and eye-healthy subjects (control group). METHODS: Twenty-nine consecutive patients with TAO (79% female) and 30 eye-healthy subjects (60% female) were included in this prospective, age- and sex-matched study. The IOP measurement with Corvis, ORA, GAT, iCARE, and central corneal thickness (CCT) with Corvis was obtained from all study participants. RESULTS: The mean age of the patients was 51 ± 10 years in patients with TAO and 56 ± 13 years in the control group. The mean IOP measurements with GAT, Corvis, ORA, and iCARE were 15.93 ± 4.42 mmHg, 18.10 ± 7.54 mmHg, 18.40 ± 7.93 mmHg, and 16.61 ± 7.96 mmHg in patients with TAO and 14.52 ± 3.02 mmHg, 14.48 ± 3.38 mmHg, 15.29 ± 4.64 mmHg, and 14.13 ± 3.85 mmHg in the control group (P = 0.157, P = 0.004, P = 0.017, and P = 0.176 respectively). The mean CCT was 547.5 ± 39.2 µm in patients with TAO and 560.8 ± 49.8 µm in the control group ( P= 0.261). CONCLUSIONS: The data collected shows an agreement between the iCARE and GAT IOP measurements in TAO patients and in eye-healthy patients. However, the mean value of IOP measurements with Corvis and ORA was significantly higher in patients with TAO in comparison with the control group (P = 0.044 and P = 0.029 respectively).

Overexpression of collagen XIII in extraocular fat affected by active thyroid-associated ophthalmopathy: A crucial piece of the puzzle?

Thyroid-associated ophthalmopathy (TAO) causes irreversible increase in extraocular fat volume that contributes to the risk of exophthalmos and compressive optic neuropathy. Collagen XIII is implicated in uncontrolled cell growth in some tumours, but we are not aware of any studies of collagen XIII in TAO-affected solid tissue to date. We conducted immunohistochemical staining for collagen XIII alpha 1 (COL13A1), present in both the transmembrane and cleaved forms of collagen XIII, in consecutive prospectively collected human extraocular tissue specimens from patients with TAO and controls. We identified overexpression of collagen XIII in active TAO-affected fat. We discuss how species and cell-type specific responses of collagen XIII to stressors may help explain the different phenotypes of TAO.

Constitutively low expression of collagen XIII alpha 1 may help explain the vulnerability of the inferior rectus muscle to thyroid-associated ophthalmopathy.

Thyroid-associated ophthalmopathy (TAO) has a predilection for inferior rectus muscle that has never been explained. We conducted immunohistochemical staining for the soluble cleaved form of collagen XIII alpha 1 (COL13A1) and found constitutively low expression of COL13A1 in normal human inferior rectus muscles and moderate expression of COL13A1 in normal human medial rectus muscles. COL13A1 is known to be essential to development and maintenance of neuromuscular junctions and there is some evidence to suggest it may help support normal immune function. The combination of constitutively low expression of COL13A1, high physiological and metabolic demands, and consequentially relatively high exposure to stressors via the blood stream may help explain the particular vulnerability of inferior rectus to TAO compared to other extraocular muscles.

Evaluation of a short-term topical interferon α-2b treatment for histologically proven melanoma and primary acquired melanosis with atypia.

OBJECTIVE: To evaluate the efficiency of series of 6-week treatments with brief intervals (6-week = 1 cycle) of topical Interferon α-2b (IFNα-2b) treatment in primary acquired melanosis (PAM) with atypia and melanoma of the conjunctiva. PATIENTS AND METHODS: Five patients with biopsy-proven PAM with atypia and seven patients with melanoma of the conjunctiva, treated with topical IFNα-2b (1 million units/ml, 5 times daily), were included in the study. All patients had colour photographs and the tumour area was measured manually for each patient before and after treatment. RESULTS: The median age of 12 patients at initiation of treatment was 61.5 years (range 39-75 years). The mean therapy duration was 2.4 cycles (range 1-6 cycle). Compared to pretreatment lesion dimension, the mean decrease in tumour size were after the first cycle 66% (range 18-98%; p = 0.004; n = 10 patients), after the second cycle 55% (range 10-100%; p = 0.016; n = 7 patients), and after the third cycle 74% (range 23-100%; n = 3 patients). In one patient 6 cycles of topical IFNα-2b were needed. The decrease in size was 22% after the 4(th) cycle, 34% after the 5(th) cycle, and 98% after the 6(th) cycle. CONCLUSION: Our clinical experience demonstrates promising results of topical IFNα-2b treatment for PAM with atypia and melanoma of the conjunctiva without any local or systemic side effects. However, future multicenter prospective studies are recommended to confirm the efficiency and safety of topical IFNα-2b treatment.

Ga-68-DOTA-TATE PET/CT for discrimination of tumors of the optic pathway.

PURPOSE: Symptomatic tumors of the optic nerve pathway may endanger vision. They are difficult to classify by imaging alone and biopsy may damage visual function. Tumor pathology influences treatment decision and a diagnostic tool with a high sensitivity and specificity would therefore be invaluable. We hypothesized that Ga-68-DOTA-TATE PET/CT may help in discriminating optic nerve tumors as uptake of somatostatin is elevated in meningiomas. MATERIAL AND METHODS: Ga-68-DOTA-TATE PET/CT was used to examine 13 patients with ambiguous, symptomatic lesions of the optic pathway for treatment planning. The presence or absence of meningioma was validated by histopathology or supplementary diagnostic work-up. RESULTS: Ga-68-DOTA-TATE PET/CT identified 10 meningiomas (en plaque = 1, optic nerve sheath = 4, sphenoidal = 5) correctly via increased SSTR (somatostatin receptor) expression (mean SUVmax (maximum standardized uptake value) = 14.3 ± 15.4). 3 tumors did not show elevated Ga-68-DOTA-TATE uptake (SUVmax = 2.1 ± 1.0). Subsumizing all clinical-radiological follow-up tools available, these lesions were classified as an intracerebral metastasis of an advanced gastric carcinoma, histologically proven inflammatory collagenous connective tissue and presumed leukemic infiltration of a newly diagnosed chronic lymphocytic leukemia. In this case series, Ga-68-DOTA-TATE PET/CT demonstrated both a sensitivity and specificity of 100%. Yet, the golden standard of histopathology was only available in a subset of patients included. CONCLUSION: Ga-68-DOTA-TATE PET/CT proved to be a valuable diagnostic tool for the correct classification of equivocal, symptomatic tumors of the anterior optic pathway requiring therapy. PET/CT results influenced therapy decision essentially in all cases.

Dermis fat grafts as primary and secondary orbital implants.

INTRODUCTION: This study was performed to evaluate the outcome after autologous dermis-fat graft [DFG] orbital implants in a large sample. MATERIALS AND METHODS: A retrospective chart review of all primary and secondary DFGs in a 16-year period was done. Aesthetic and functional results, patients' satisfaction and postoperative complications were evaluated. RESULTS: In total 468 DFGs were performed in the study period (315 primary [I°] and 153 secondary [II°] DGFs). In the analysis, 173 DFG I° and 66 DFG II° were included as sufficient follow-up was available. Median follow-up after DFG I° was 21.5 months and 14 months after DFG II°. After DFG I°, in 76% of patients motility of the graft was possible in all directions; 81% had good fitting of the prosthesis and 83% were highly satisfied with the results. Mean width of palpebral apertures was 0.2 mm smaller and Hertel exophthalmometry revealed a mean enophthalmus of 1.6 mm on the operated side compared to the fellow-eye. After DFG II°, motility was possible in all directions in 34% of patients. Fitting of the prosthesis was good/reasonable in 49%/41% and patients were highly satisfied in 57%. On average, on the operated side palpebral apertures were 0.6 mm smaller and Hertel measurements showed an enophthalmus of 2.6 mm. Major complications were uncommon. Complete necrosis of the implant was more often observed after II° (6.1%) than after I° DFG (3.5%). DISCUSSION: In this large sample, DFG proved to be an effective and safe method for the reconstruction of anophthalmic sockets.

[Enucleations, eviscerations and orbital implants in German eye hospitals]. / Enukleationen und Eviszerationen sowie die Verwendung von Orbitaimplantaten in deutschen Augenkliniken.

BACKGROUND: Evaluation of the number of enucleations and eviscerations performed in Germany and the orbital implants used. METHOD: Analysis of the quality reports of German ophthalmological clinics for the years 2012-2021 provided by the Federal Joint Committee (Gemeinsamer Bundesausschuss, G­BA). RESULTS: Almost 10 times as many enucleations (8368) as eviscerations (975) are performed in Germany. After enucleation, alloplastic implants are used most frequently (44.6% alloplastic, no further specification, 30.0% alloplastic coated, no further specification; 14.1% microporous implants) and autologous dermis-fat grafts in 6.1% of the cases. CONCLUSION: In Germany, significantly more enucleations than eviscerations are performed. Alloplastic orbital implants are preferred for primary reconstruction following enucleation.

Compression Dressing versus Noncompressive Transparent Eye Shield after Ptosis Surgery.

Background: We aimed to investigate the effect of compression dressing on edema, ecchymosis, pain, and ocular surface irritation after ptosis surgery. Methods: After ptosis correction [anterior levator reinsertion (and resection) (ALR), if necessary additional blepharoplasty], the eye was randomized for compression dressing or transparent eye shield. Edema and ecchymosis were scored on a four-point rating scale by a blinded observer 1 day (D1), 1 week (D7), and 8 weeks (D56) after surgery; the same was done for scar formation regarding redness and bulging at D7 and D56. Aesthetic outcome was ranked by patient and blinded observer using the Global Aesthetic Improvement Score at D1, D7, and D56. Postoperative pain was scored using a visual analogue scale (0 to 10) at D1. Impairment after surgery by dressing or eye shield was evaluated at D1. Results: Ecchymosis, edema, scar formation, and aesthetic outcome ranked by the patient and blinded observer did not differ between the groups with compression dressing and eye shield at any day of follow-up (P > 0.05). Postoperative pain and impairment were the same in both groups (P > 0.05). One case of corneal erosion occurred in the group with compression dressing at D1 (P = 0.342). At D7, corneal staining was increased in the group without compression dressing (P = 0.930). Conclusions: Compression dressing after ALR does not reduce ecchymosis, edema, or postoperative pain and has no effect on early scar formation or aesthetic results. To prevent corneal erosion caused by the dressing, it can be omitted after ALR without inferiority for the early postoperative results.

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.

[Thyroid Eye Disease-Compressive Optic Neuropathy]. / Optikuskompression bei endokriner Orbitopathie.

BACKGROUND: The aim of this study was to evaluate the functional outcomes in terms of best-corrected visual acuity (BCVA) and visual field (VF) defects in optic nerve compression (thyroid eye disease-compressive optic neuropathy, TED-CON) patients after treatment. PATIENTS AND METHODS: In this observational, retrospective study, the medical charts of 51 patients (96 eyes) with a diagnosis of definitive TED-CON between 2010-2020 were included. RESULTS: After the diagnosis of TED-CON, 16 patients (27 eyes) received steroid-pulse (medical) treatment alone, 67 eyes received an additional surgical orbital decompression, whereas 1 patient (2 eyes) refused both treatment methods. In 74 eyes (77.1%) we detected an improvement of the BCVA ≥ 2 lines after the treatment over a mean time interval of 31.7 weeks (with no significant difference between treatment methods). In 22 eyes (27.2%) out of the 81 that underwent a posttreatment VF examination, we observed a complete resolution of the defects over a mean time interval of 39.9 weeks. When we limited analysis to patients with a minimum follow-up of 6 months at last visit, we found 33 eyes (61.1%) out of 54 eyes still had a VF defect. CONCLUSION: In our data, more than half of the TED-CON cases (61.5%) had a good prognosis with a final BCVA ≥ 0.8  at the last visit; however, only 22 eyes (27.2%) showed a complete resolution of VF defects, while 33 eyes (61.1%) had residual defects measured after a minimum follow-up of 6 months. These results suggest that while the BCVA recovers relatively well, the VF of patients is likely to remain marked by optic nerve compression.
