Purpose: To evaluate the efficacy of treatment of diffuse diabetic macular oedema (DME) with difluprednate ophthalmic emulsion 0.05% (Durezol™) in eyes before vitrectomy.
Methods: This study enrolled patients with diffuse DME for whom more than 3 months had passed since prior treatment. Nineteen eyes in 15 subjects were treated with difluprednate ophthalmic emulsion 0.05% four times daily for the first month and then twice daily for 2 months (treatment group). As a control group, 22 eyes in 11 subjects with DME were selected from subjects who underwent the steroid responder test.
Results: In the treatment group, the mean visual acuity (VA) (±SD) was 0.38 ± 0.25 logMAR and mean retinal thickness was 461.1 ± 109.9 μm at baseline. After 1 month of treatment, the mean VA had improved to 0.29 ± 0.25 (Wilcoxon rank‐sum test, p = 0.30), while mean retinal thickness had decreased to 372.1 ± 70.0 μm (p = 0.006). The rate of effective improvement in retinal thickness was 42% and that of VA was 26%. In the control group, changes in neither VA nor retinal thickness were significant.
Conclusions: Eye drop therapy using difluprednate ophthalmic emulsion 0.05% is a useful and effective treatment modality without surgical intervention or severe side‐effects.
Background
Metastatic tumors in the orbit, especially from gastric cancer, are rare. We present a rare case of extraocular muscle metastasis from gastric cancer and raise consideration of metastasis to extraocular muscle as a differential diagnosis of proptosis/lid swelling in a patient with history of malignancy.
Case presentation
A 54-year-old Japanese woman presented with proptosis, lid swelling, diplopia, and retro-orbital pain in her left eye, which she had been experiencing for 1 day. She had a medical history of poorly differentiated adenocarcinoma of the stomach, which had metastasized to several organs. A computed tomography scan showed enlargement of the medial rectus muscle in her left eye. She was diagnosed as having gastric cancer metastasis to the medial rectus muscle of her left eye, and received a total of 20 Gy radiation therapy to the orbit, which resulted in resolution of her ocular symptoms. She died 3 months after her initial visit to our ophthalmic department.
Conclusions
Metastasis from malignancy should be considered in the differential diagnosis of a patient presenting with proptosis or lid swelling who has a history of gastric cancer. Radiation therapy of metastases in the orbit may be an effective treatment in such cases.
The AM transplantation procedure may be an effective option for treating corneal perforations when the wound is circular or irregular, except for incised wounds. Our "Pleats Fold" AM transplantation technique can achieve definite closure and effectively repair wounds of various sizes. Postoperative astigmatic values were acceptable. Therefore, we recommend this procedure for repairing lesions <3 mm in diameter that do not involve the central cornea and that are infection free.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
