RESUMO
PURPOSE: The aim was the comparison of two different approaches to re-insert the inferior eyelid retractors within addition to lateral tarsal strip at lower eyelid involutional entropion (LEIE) surgical correction. METHOD: This multicentric retrospective case series involved 233 consecutive patients (195 eyelids) who underwent LEIE repair. All the lids had a lateral tarsal strip (LTS) in addition to the reinsertion of retractors onto the tarsal plate via the anterior approach (group 1) or the posterior approach (group 2). The desired normal position of the eyelids at 6-month follow-up was considered 'surgical successes, while entropion recurrence and overcorrection (ectropion) were considered 'surgical failures'. RESULTS: One-hundred ninety-one (82%) surgeries were included in group 1 and 42 (18%) in group 2. The success rate was 92.1% (176 lids) in group 1 and 85.7% (36 lids) in group 2 (p = 0.188). The recurrence rate was statistically higher for group 2 (14.3%) than for group 1 (3.7%) (p = 0.016). Overcorrection only described in group 1 (3.1%). Both groups had a similar complication rate (p = 0.268), with trichiasis being the most frequent (14, 6%). Ten eyelids (47.6%) from the 21 overall failures were satisfactorily reoperated, and the remaining ones were treated conservatively. CONCLUSION: The anterior or posterior approach to reinsert lower eyelid retractors to tarsal plate in addition to LTS to correct LEIE can provide a similar outcome. However, the anterior approach achieves a slightly higher success rate with fewer recurrences but with a higher overcorrection rate.

PURPOSE: To assess with Bézier curves the outcomes of Müllerotomy with anterior graded Müller muscle disinsertion for the treatment of Graves upper eyelid retraction (UER). METHODS: Eighty-six eyelids of 52 inactive GO patients operated from November 2018 to June 2021 were included in this study. All measurements were performed on Bézier curves adjusted to the upper lid contour with a previously validated algorithm. Lid contour was classified regarding grade of superposition (GS) as excellent (GS > 90%), good (GS 85-90%) or poor (< 85%). Surgical success was defined as complete or partial if postoperative grade of asymmetry was < 10% with an excellent or good lid contour, respectively. RESULTS: The mean age was 51 ± 10.4 years with a range from 31 to 78 years and a mean follow-up of 14.4 ± 7.4 months. There was a significant improvement of median GS (p < 0.0001) from preoperative (74.3%; 10.7 IQR) to postoperative values (91.7%; 6.3 IQR). A normalization of postoperative contour peak (- 0.69; 1.27 SD) and MPLD90 (4.2 mm; 0.8 SD) was noticed (p < 0.0001). Postoperative lid contour was excellent in 62 (72%), good in 16 (19%) and poor in 8 eyelids (9%). Surgical success was achieved in 42 patients (81%), from which 34 (81%) were complete. Reintervention was required in 14 eyelids (16%). CONCLUSIONS: Measuring surgical outcomes with Bézier curves allows an automated, complete and objective assessment, giving more consistency to our data compared to previous reports. Müllerotomy with graded Müller muscle disinsertion is a safe and effective procedure for Graves UER, offering predictable results.

AIMS: To define and quantify the upper lid contour by adapting Bézier curves with a newly developed software in normal subjects, assessing their reliability. METHODS: Fifty eyes of 50 healthy patients with no ocular pathology were included in this study from October 2020 to November 2020. All measurements were performed on Bézier curves adjusted to the upper lid contour. An original software was used to measure the radial and vertical midpupil-to-lid margin distances (MPLD), temporal-to-nasal (T/N) ratios, contour peak location and grade of superposition (GS) and asymmetry (GA) indexes. We calculated differences in the variables measured regarding age, gender or the side of the eye being assessed. RESULTS: The mean Bézier curve showed an excellent level of inter-rater reliability (intraclass correlation coefficient of 0.99). The median GS index of each eyelid to the mean Bézier curve was 95.4%, 8.5 IQR, and the median GA index was 3%, 3.4 IQR. The mean contour peak location was -0.35 mm, SD 0.45. Overall, the mean central MPLD was 4.1 mm, SD 0.6. No significant differences were found between male and female patients in variables derived from Bézier curves. CONCLUSION: Bézier curves may become a very useful tool for the assessment of upper lid contour, contour peak and symmetry. GS and GA indexes, along with the T/N area ratio are potential outcomes for this purpose. All current variables can be obtained just from one single Bézier curve measurement. Our results offer an in-depth exhaustive description of these variables and their distribution in the normal population.

OBJECTIVE: To report outcomes of strabismus surgery in thyroid eye disease using intraoperative bow-knot adjustable sutures under topical anaesthesia and calculate prediction models for surgical correction and postoperative drift depending on surgical dose-response. METHODS: We retrospectively reviewed patients operated on from 2016 to 2021. A satisfactory outcome was defined as no diplopia with maintenance of vertical (<5 PD) and horizontal (<10 PD) stable alignment at primary gaze. Subjective diplopia corrected with prisms within successful motor alignment was defined as a fair result. Otherwise, the result was considered to be poor. RESULTS: A total of 73 patients were included (60 females, 82%). Mean preoperative horizontal and vertical deviations were 26.9 PD (19.1 SD), and 11.8 PD (7.6 SD), respectively. Mean horizontal drift was -3.2 PD (5.2 SD), whereas mean vertical drift was -3.4 PD (3.3 SD). A linear regression established a dose-response of 2.37 PD/mm for each medial rectus recession (p < 0.0001; r2â¯=â¯0.777) and 3.75 PD/mm for unilateral inferior rectus recession (p < 0.0001; r2â¯=â¯0.922). Final success rate was satisfactory in 62 patients (85%), fair in 7 patients (10%), and poor in 4 patients (5%). CONCLUSIONS: Muscle recession with intraoperative adjustable sutures is effective for the treatment of thyroid eye disease strabismus. Predictable dose-responses could be achieved with a drift toward overcorrection. Undercorrection proportional to the planned surgical dose should be the immediate postoperative target of choice. Other variables such as orbital decompression and concurrent vertical and horizontal surgery do not correlate with dose-response and postoperative drift. However, further studies are necessary to validate our findings.
RESUMO
A 71-year-old male with a 4-month history of bulging, tearing, and redness in the right eye presented with vision loss, proptosis, conjunctival hyperemia, and chemosis. Magnetic resonance imaging showed a right intraconal solid mass with extraconal extension, hyper-intense in T2 sequences with heterogeneous contrast enhancement. Complete excision of the mass was performed through a lateral orbitotomy. Histological analysis revealed a neoplasm with high vessel density, solid growth of oval cells, a concentric proliferation of the wall of small vessels, and a weak and patchy positivity for smooth muscle actin. These findings were consistent with the diagnosis of myopericytoma. After surgery, visual acuity improved in the affected eye and after 18 months of follow-up there have been no signs of recurrence.

BACKGROUND: While ptosis is a well-known consequence of glaucoma surgery, some isolated case reports point to the possibility of upper eyelid retraction occurring after glaucoma surgery. This study aims to analyze the occurrence of ptosis and eyelid retraction after glaucoma surgery and to evaluate factors contributing to these palpebral fissure changes. METHODS: Cross-sectional study including 100 eyes of 100 patients that had undergone unilateral glaucoma surgery. Upper eyelid height in the operated eye was measured by digital photography and compared with the fellow, non-operated eye. The main outcome was to determine if ptosis or retraction occurred in the operated eye in comparison with the fellow eye. The secondary outcome was to determine if any variable was associated with ptosis or retraction. A clinically significant difference (either toward ptosis or retraction) was defined as a difference ≥1â mm between both eyes. RESULTS: Of 100 eyes included 81 (81%) showed no change in eyelid height (-0.133â mm ± 0.496), 11 (11%) showed ptosis (-1.348â mm ± 0.387) and 8 eyes (8%) showed retraction (1.705 ± 0.634). A statistically significant relation was found between ptosis and pseudoexfoliation glaucoma (p = 0.003). A trend toward lower postoperative IOP and higher conjunctival blebs was found in eyes with postoperative eyelid retraction. CONCLUSIONS: Eyelid retraction was present in 8% of patients and ptosis in 11%. Patients with eyelid retraction showed around a 3â mmHg lower postoperative IOP than eyes without retraction. The presence of pseudoexfoliation may be a risk factor for this complication. A prospective study with a large number of patients would be required to confirm these results.

Purpose: Coronavirus Disease 2019 (COVID-19) can cause conjunctivitis in up to 31.6% of patients. Additionally, retinal findings compatible with retinal microvascular ischemia have also been associated with coronavirus disease in asymptomatic patients. We describe a case of bilateral retinal changes compatible with microangiopathy occurring during the late phase of COVID-19.Case report: A 50-year-old man with bilateral pneumonia and positive polymerase chain reaction for SARS-CoV-2 developed an arcuate visual field defect in his left eye. Funduscopy revealed multiple, bilateral cotton-wool spots without haemorraghes. OCT-angiography revealed multifocal areas of retinal microvascular ischemia in the superficial plexus, the largest of which corresponded to the arcuate scotoma observed in the automated perimetry.Conclusion: Visual field defects due to retinal microangiopathy can occur during the late phase of COVID-19. Vascular changes observed in the retina may mimic what may be happening in other, less-accessible organs.
