Purpose: We analyzed factors that affect the outcome of levator recession surgery for upper eyelid retraction in patients with thyroid-associated ophthalmopathy.Methods: Retrospective analysis was performed based on the medical records of 24 patients with thyroid-associated ophthalmopathy who underwent upper eyelid levator recession surgery between February 10, 2010, and September 18, 2018. The margin to reflex distance (MRD), length and area of the upper and lower eyelids were measured and compared with the eyelid analysis software before and after 6 months of surgery on medical records. In addition, factors affecting the difference in MRD1 before and after surgery were examined by multivariate linear regression analysis.Results: Twenty-four patients were included in the study. The MRD1 decreased significantly from 5.12 ± 1.26 mm before surgery to 3.48 ± 1.08 mm at 6 months after surgery (p < 0.001). All upper eyelid measurements, i.e., UEL (p < 0.001), UMA (p < 0.001), UCA (p = 0.004), and ULA (p < 0.001), were significantly decreased after surgery, while none of the lower eyelid measurements showed significant changes. Multivariate logistic regression analysis indicated that lower preoperative MRD1 was associated with the success of the surgery (odds ratio, 0.31; 95% confidence interval, 0.09-1.01).Conclusions: Levator recession surgery is an efficient surgical method that can correct the upper eyelid retraction associated with thyroid-associated ophthalmopathy.

In this paper an extremely rare case of primary bilateral eyelid meibomian gland epithelioma in a dog is presented. Meibomian tumors arise from the meibomian (tarsal) glands on the inner aspect of the eyelid, and meibomian gland adenomas and adenocarcinomas are the most frequent neoplasia arising from those glands. A 10-year-old male dog was admitted, with ophthalmic signs of periorbital swelling of the right eye. During the last two years, the dog had a progressive engorgement of the upper eyelid of the right eye, and during the past few months, strabismus and exophthalmos were also noticed, as well as a slighter enlargement on the lower eyelid of the left eye. Upon ophthalmic examination strabismus and periorbital swelling at the lateral canthus of the right eye, accompanied by mild exophthalmos and lagophthalmos, were recorded. Also, deep ulcerative keratitis with corneal oedema and neovascularization were noticed. Intense chemosis, epiphora and a small pinkish mass arising from the palpebral conjunctiva of the left lower eyelid were also seen. Neoplasia of both eyelids was suspected, and a series of diagnostic examinations were carried out. Orbital exenteration of the right eye was performed in the first place, followed by surgical removal of the mass of the left eyelid one month later. Based on clinical and histopathological findings, meibomian gland epithelioma was diagnosed. No relapse or metastases (local or distant) were observed in re-examinations within 18 months after the surgery. This study shows that although meibomian gland epithelioma is rare, it should be considered in the differential diagnosis of cases of orbital and eyelid tumors. Even though this tumor shows low malignancy, prompt surgical intervention and extended excision is the treatment of choice, in order to preserve vision in some cases. To the authors’ knowledge, the present case is the first report of bilateral meibomian gland epithelioma in the veterinary literature.

Background/purpose: To report the results of our clinical study on the efficacy of a ‘Lateral Sliding Flap’: A one-step technique for lower or upper eyelid reconstruction. Methods: Retrospective analysis of a consecutive case series of patients treated with a ‘Lateral Sliding Flap’ following tumour removal by horizontal block excision. In this technique a (medium-sized) defect of up to 50% of the eyelid was reconstructed by disinsertion of the lateral canthus, medial advancement of the lateral (remaining) (full-thickness) eyelid and a laterally-based horizontal skin-muscle advancement flap, followed by canthal fixation. We recorded the operating time and evaluated the postoperative eyelid apposition, lid contour, complications and frequency and type of re-operation. The outcome was scored (according to four grades (excellent/good/fair/ poor) of lid apposition and contour. Results: Seven consecutive patients, all treated by one oculoplastic surgeon in one year, were included. Six were female, one was male. Five had lower eyelid defects, two had upper eyelid defects of 40-50% of the horizontal width. The average age was 67,9 years, ranging from 52 to 85 years. The mean postoperative follow-up time was 31 months, ranging from 21-43 months. The average duration of the reconstruction was 31 minutes (ranging from 25 to 38 minutes). The outcome was excellent in 3 patients, good in 3 patients and fair in one patient. (Some) lash loss may be encountered. No complications such as flap ischemia of necrosis were noted. No re-operation was required. Conclusion: The ‘Lateral Sliding Flap’ is an efficaceous, one-step technique for reconstruction of defects of up to 50% of the lower or upper eyelid. With the technique a normal eyelid margin is created at the level of the cornea for optimal visual function and comfort. Compared to Tenzel’s semicircular rotation flap, the ‘lateral sliding flap’ results in a shorter vertical scar and “Hidden” horizontal scars in the relaxed skin tension lines.

Background: Eyelid tumors are rare skin cancers, the most common of which is basal cell carcinoma characterized primarily by local growth. In addition to surgery, radiotherapy is among the basic methods of treatment. External beam radiotherapy is associated with the risk of complications within ocular structures, especially the lens. In the case of interstitial brachytherapy, it is possible to administer a high dose to the clinical target volume (CTV), while reducing it in the most sensitive structures. Methods: This paper presents the results of an analysis of 28 patients treated with interstitial high dose rate (HDR) brachytherapy for skin cancers of the upper and lower eyelid; medial and lateral canthus; and the cheek, nose and temples with the infiltration of ocular structures. The patients were treated according to two irradiation schedules: 49 Gy in 14 fractions of 3.5 Gy twice a day for 7 days of treatment, and 45 Gy in 5 Gy fractions twice a day for 5 days. The mean follow-up was 22 months (3–49 months). Results: two patients (6%) had a relapse: a local recurrence within the irradiated area in one of them, and metastases to lymph nodes in the other. The most common early complication was conjunctivitis (74%), and the most common late complication was dry eye syndrome (59%). Conclusions: Interstitial HDR brachytherapy for skin cancers of the upper and lower eyelid; medial and lateral cants; and the cheek, nose and temples with infiltration of ocular structures is a highly effective, short and relatively low burden type of treatment.

Abstract Background Oxymetazoline hydrochloride 0.1% ophthalmic solution has recently been approved in the United States for the treatment of ptosis. Objectives The aim of this study was to assess the upper and lower eyelid position as well as the brow position and the color of the sclera following the ophthalmic administration of oxymetazoline hydrochloride 0.1%. Methods In this prospective cohort study, consecutive patients presenting with ptosis received topical oxymetazoline 0.1%. The primary outcome was measurement of the upper eyelid height (margin-to-reflex distance 1 [MRD1]) and lower eyelid height (MRD2) relative to the center of pupil, along with assessment of brow height, measured on photographs at baseline and 2 hours after instillation of oxymetazoline. The secondary outcome was the assessment of the color of the sclera (eye whiteness) before and after treatment with a novel color space algorithm. Results Twenty-nine patients participated in the study. The mean [SD] MRD1 at baseline was 2.3 [0.6] mm. At 2 hours following oxymetazoline treatment, the mean MRD1 significantly increased to 4.2 [0.9] mm (P &lt; 0.01). The mean MRD2 also significantly increased from 5.3 [0.9] mm to 5.7 [1.0] mm (P &lt; 0.01). Brow position did not change with treatment (P = 0.4). Following treatment, the eye sclera became significantly whiter, with a mean ΔEab (color change) of 9.7 [3.9], with 57 out of 58 eyes experiencing a significant change in color. A change of ΔEab ≥2 is considered visually perceptible to the human eye. Conclusions Within 2 hours of use, oxymetazoline significantly improves the size of the palpebral aperture (MRD1 + MRD2) and also makes the eye appear significantly whiter. Level of Evidence: 4

Background. Involutional entropion and upper eyelid ptosis are common eyelid diseases in the elderly population. They represent a frequent cause of discomfort and often result in significant visual and functional impairment. The surgical management of these disorders includes various treatment options and techniques and is usually carried out in multiple time sessions. Case Report. We report the case of a 72 year old female patient, suffering from right eye involutional lower eyelid entropion and ptosis, who was treated synchronously for both conditions, by applying the lateral tarsal strip procedure and the levator resection technique. Conclusion. The synchronous treatment of involutional entropion and ptosis is an alternative treatment strategy, which could potentially improve surgical outcome, while reducing postoperative recovery time and treatment costs.

The Southern Caracara is a bird of prey, of the family Falconidae, inhabits all the Brazilian territory, they are omnivorous birds adapted for hunting. The digestive system of the predators presents differences in their morphology due to their eating habits. Knowing the importance of the gastrointestinal system, this study aims to carry out a histological study of the tongue, esophagus and the crop of Polyborus plancus. For this purpose, eight avian of both sexes, with different body weights and ages were used, they were euthanized and the organs were collected, fixed, dehydrated and stained with hematoxylin-eosin. It was noted that the tongue has stratified squamous epithelium with mucous glands and with different degrees of keratinization. The esophagus and crop have four well developed muscle layers and mucous glands. Additionally, in the crop there is presence of an adventitious layer that consists of loose connective tissue. We conclude that the tongue, the esophagus and the crop of the Southern Caracara have similar histological organization of several birds like the Pekin Ducks, ostriches, domestic chicken and partridges.
