Inferior displacement of the lower eyelid during intraoperative quantification in blepharoptosis surgery

Hirohiko Kakizaki, Yasuhiro Takahashi, Masahiro Zako, Masayoshi IwakiDepartment of Ophthalmology, Aichi Medical University, Nagakute, Aichi, JapanPurpose: To examine inferior displacement of the lower eyelid during eye closing in intraoperative quantification of blepharoptosis surgery.Methods: A series of lower eyelid movements during eye closing in intraoperative quantification of blepharoptosis surgery were examined in 30 eyelids of 15 patients (6 males and 9 females; mean age 70.0 years; range 43–81 years) with bilateral aponeurotic blepharoptosis.Results: Inferior displacement of the lower eyelid was observed in all eyelids examined, although the extent varied in each patient (range 2.0–4.5 mm; mean 3.2 mm). Inferior displacement occurred with upward eye movement caused by Bell's phenomenon. Many wrinkles were simultaneously observed as a result of contraction of the orbicularis oculi muscle. After maintaining the inferiorly displaced state for several seconds, 20 lower eyelids in 10 patients naturally moved superiorly to a resting position. On the other hand, 10 lower eyelids in 5 patients remained in the same inferior position for more than 5 seconds, after which we had to manually elevate them to a resting position. The eyes then moved inferiorly to their resting position with a decrease in the number of lower eyelid wrinkles. Once the patients opened their eyes, inferior displacement of the lower eyelid completely disappeared.Conclusions: Inferior displacement of the lower eyelid during eye closing increases the amount of lagophthalmos. This phenomenon needs to be considered for quantifying the intraoperative lagophthalmos level during blepharoptosis surgery.Keywords: blepharoptosis surgery, eye closing, inferior displacement, intraoperative quantification, lower eyelid&nbsp

Severe anterior uveitis associated with idiopathic dacryoadenitis in diabetes mellitus patient

A 38-year-old woman with diabetes mellitus complained of acute visual loss in the left eye (20/200) and swollen left upper eyelid. Slit lamp examination of the left eye revealed ciliary injection, posterior synechia iritis, numerous inflammatory cells, and fibrin exudates in the anterior chamber. T1-weighted enhanced magnetic resonance imaging demonstrated left lacrimal gland enhancement with inflammatory spread to the left anterior ocular segment. Blood examination showed increased blood sugar but the other components were within normal limits. The patient was treated with steroid pulse therapy (methylprednisolone 1 g/day × 3 days) under a blood sugar control regimen in consultation with an endocrinologist, after which additional peribulbar injection of triamcinolone acetonide (40 mg) was performed. Resolution of the anterior uveitis and the dacryoadenitis was obtained after 2 months and there was no recurrence 1 year after the therapy. This is a rare case of severe anterior uveitis caused by idiopathic dacryoadenitis in a patient with diabetes mellitus

The rate of symptomatic improvement of congenital nasolacrimal duct obstruction in Japanese infants treated with conservative management during the 1st year of age

This study aimed to examine the rate of symptomatic improvement of congenital nasolacrimal duct obstruction (CNLDO) in Japanese infants treated with conservative management within the 1st year of age. Thirty-five lacrimal ducts in 27 patients diagnosed with CNLDO were included in the study. During the observational period, lacrimal ducts were massaged. As well, antibiotic eye drops, to be administered 4 times a day, were sometimes prescribed for obvious conjunctivitis. Two lacrimal ducts in 2 patients were probed before the 1st year of age because of dacryocystitis or severe blepharitis; these patients were included in the unimproved group. Twenty-nine lacrimal ducts in 21 patients resolved during the period (82.9%); with 16 lacrimal ducts resolving before six months of age. Therefore, a comparatively high percentage of resolution for CNLDO (82.9%) following conservative management was shown before the 1st year of age in Japanese infants

Inferior oblique muscle thickness in Asians

The purpose of this study was to examine the inferior oblique muscle (IOM) thickness in Asians by the quasi-sagittal plane of the orbits. Specimens were examined from 23 orbits of 18 Asians (9 orbits in males, 14 in females), aged 63 to 97 years at death. All specimens were fixed in 10% buffered formalin before use. The orbital contents were incised parallel to the optic nerve, after which the lengths of both short and long axes of the IOM were measured and the ratio of short to long axes was calculated. The mean lengths of each short or long axis of the IOM were 2.27 ± 0.49 mm and 7.23 ± 0.97 mm, respectively. The average ratio was 0.32 ± 0.07. There were no significant differences in laterality or gender. This study determined the normal IOM thickness in Asian cadavers, the outcome of which could be useful for detection of IOM involvement in Graves’ orbitopathy

Linear Basal Cell Carcinoma in an Asian Patient

Linear basal cell carcinoma (BCC), which has a ratio of its long and short axes of more than 3: 1, is a distinct clinical entity among BCC. We report the first case report of a linear BCC in an Asian patient. An 87 year-old woman presented with an ulcerated black nodule, 15×5mm (3: 1), on her nasojungal fold of the right lower eyelid. The tumor was excised with 5 mm safety margin. The pathological examination confirmed the tumor was a BCC with a clear margin. Diagnosis of a linear BCC is based on its morphological features and occurrence along the wrinkle line, which needs to be also considered in Asian

Upper eyelid retraction disclosed after edrophonium chloride administration in a patient with Graves’ orbitopathy and myasthenia gravis

Patients with Graves’ orbitopathy have a higher probability of myasthenia gravis than does the normal population. Overlapping clinical features cause diagnostic confusion in such a situation. We herein report a patient with Graves’ orbitopathy and myasthenia gravis (GO-MG) with normal left eyelid height, but in whom upper eyelid retraction was shown after edrophonium chloride administration. Upper eyelid retraction in GO-MG is occasionally masked by a myasthenia effect. The upper eyelid height must be carefully monitored in patients with Graves’ orbitopathy to detect the presence of concomitant myasthenia gravis

The importance of rim removal in deep lateral orbital wall decompression

Purpose: To evaluate the surgical outcome of deep lateral orbital decompression with or without rim removal. Design: Retrospective case series. Methods: Thirty-two patients (47 orbits) with Graves’ orbitopathy who underwent simple deep lateral decompression or balanced lateral plus medial decompression. Of the 14 patients (24 orbits) who underwent simple deep lateral decompression, 8 (13 orbits) had temporary rim removal and in 6 (11 orbits) the rim was left intact. Of the 18 patients (23 orbits) who underwent a balanced decompression, 7 (9 orbits) had temporary rim removal and in 11 (14 orbits) the rim was left intact. The amount of postoperative reduction in proptosis was compared among these four groups. Results: The average reduction in proptosis in the simple deep lateral decompression group was 5.73 mm (range: 4.0–8.0 mm) in the rim removal group and 4.09 mm (range: 2.5–6.0 mm) in the intact rim group (P = 0.005). The average reduction in proptosis in the balanced decompression group was 6.39 mm (range: 5.0–8.5 mm) in the rim removal group and 5.07 mm (range: 3.0–8.0 mm) in the intact rim group (P = 0.039). There was no statistically significant difference in proptosis reduction between the simple deep lateral decompression with rim removal group and the balanced decompression with an intact rim group (P = 0.220). Conclusion: The rim removal approach allows a more effective decompression than the intact rim approach. Simple deep lateral decompression with rim removal approach has a similar effect to balanced decompression through an intact rim.Kakizaki H, Takahashi Y, Ichinose A, Iwaki M, Selva D and Leibovitch
