“…This may be accidental, and delayed maxillary sinus mucocoele development has been shown to occur years after orbital floor blow-in fracture if not reconstructed at the time of injury [2]. In our case, the trauma was iatrogenic in the form of previous sinus surgery and the Caldwell-Luc procedure remains a recognized cause of delayed mucocoele development [3].…”

Mucocoeles are cyst-like lesions of the paranasal sinuses, which may rarely erode through the bony orbit and so displace or compress orbital contents. Such patients may present to ophthalmologists and other health care professionals with diverse problems including facial pain and swelling, proptosis, double vision, ptosis, infra-orbital anaesthesia, epiphora and optic nerve dysfunction with reduced vision. We present an illustrated interventional case report of an 81-year-old gentleman with a 2-week history of swelling around the left lower eyelid and malar region associated with double vision both in the primary position and particularly downgaze. We discuss the aetiology, diagnosis and contemporary management of maxillary mucocoeles and also the Caldwell-Luc procedure. The article serves as a reminder that maxillary mucocoeles may slowly and covertly invade the orbit and should be considered in the differential diagnosis in patients presenting with proptosis, globe displacement and an orbital or adnexal mass.

“…The previous orbital fractures were functionally covered by a membrane consisting of dense fibrous tissue. commonly develops in patients between the ages of 40 and 70 years, with no difference by sex [6]. The frontal and ethmoid sinuses are the most common sites of mucocele, accounting for 60% and 30% of patients, respectively.…”

“…The degree of orbital protrusion is associated with a variety of orbital diseases, and its accurate quantification is important to diagnose certain orbital diseases and determine the effectiveness of their treatment. CT imaging has been used to measure the prominence of the eye because of its high-resolution accuracy and ability to analyze multiple views simultaneously (Kim and Choi, 2001;Nkenke et al, 2003;Fang et al, 2013). Some studies have shown that CT image-based ocular prominence measurements are more accurate (Hallin and Feldon, 1988;Segni et al, 2002;Nkenke et al, 2003;Ramli et al, 2015) and correlate well with measurements using the Hertel ocular prominence meter (Klingenstein et al, 2022).…”

“…Meanwhile, clinicians using CT scans for diagnosing the degree of exophthalmos measure the relevant distance manually by dragging the mouse after determining physiological structures, such as the outer edge of the orbit and the apex of the anterior surface of the cornea (Nkenke et al, 2003;Bingham et al, 2016;Na et al, 2019). Such a manual method of measuring exophthalmos is not only timeconsuming and inefficient but also inevitably subjective to the clinician, resulting in poor reproducibility of the interobserver measurements (Huh et al, 2020).…”

Introduction: Objective, accurate, and efficient measurement of exophthalmos is imperative for diagnosing orbital diseases that cause abnormal degrees of exophthalmos (such as thyroid-related eye diseases) and for quantifying treatment effects.Methods: To address the limitations of existing clinical methods for measuring exophthalmos, such as poor reproducibility, low reliability, and subjectivity, we propose a method that uses deep learning and image processing techniques to measure the exophthalmos. The proposed method calculates two vertical distances; the distance from the apex of the anterior surface of the cornea to the highest protrusion point of the outer edge of the orbit in axial CT images and the distance from the apex of the anterior surface of the cornea to the highest protrusion point of the upper and lower outer edges of the orbit in sagittal CT images.Results: Based on the dataset used, the results of the present method are in good agreement with those measured manually by clinicians, achieving a concordance correlation coefficient (CCC) of 0.9895 and an intraclass correlation coefficient (ICC) of 0.9698 on axial CT images while achieving a CCC of 0.9902 and an ICC of 0.9773 on sagittal CT images.Discussion: In summary, our method can provide a fully automated measurement of the exophthalmos based on orbital CT images. The proposed method is reproducible, shows high accuracy and objectivity, aids in the diagnosis of relevant orbital diseases, and can quantify treatment effects.
