Functional inferior canalicular reconstruction using a monocanalicular probe after tumor resection of the medial third of the lower eyelid.

PURPOSE: To describe a surgical technique for functionally reconstructing a lacrimal drainage duct and to assess its long-term functionality. METHODS: This observational review includes six cases involving reconstruction of the inferior canaliculus after surgical resection of lower eyelid carcinoma. Following lesion excision with safety margins, the epithelium of the distal portion of the inferior canaliculus is located and intubated with a monocanalicular probe. Subsequently, the eyelid lamellae are reconstructed without displacing the probe. The Monoka collarette is then sutured using a 10/0 nylon suture. Data collection included anatomic pathology of the lesion and data from ophthalmic examinations at each visit (including epiphora, inferior canalicular irrigation, and fluorescein dye disappearance test [FDDT]), as well as stent extrusion or other complications. RESULTS: No complications were observed during the surgeries. The stents remained in place for an average of 4months, with no extrusions prior to removal. The mean follow-up period was 4.8years (SD=2.0), during which no other complications were noted. Only one patient experienced intermittent epiphora, also present in the fellow eye. At the final visit, FDDT was normal in all eyes, and all patients demonstrated patency of the inferior canaliculus upon irrigation. CONCLUSION: Primary reconstruction of an inferior lacrimal drainage duct following tumor resection can be successfully performed, resulting in favorable functional recovery.

Orbital myositis in a patient with Crohn's disease: A case report of two episodes.

PURPOSE: To describe a case report of a 34 years-old patient with Crohn's Disease and two episodes of Ocular Myositis. METHODS: The research methodology employed in this study consisted of a retrospective review of the patient's complete medical history. RESULTS: Crohn's Disease is a chronic inflammatory bowel disorder known to be associated with a wide range of extraintestinal manifestations. Ocular abnormalities, such as episcleritis and uveitis, are commonly observed. However, orbital myositis is an extremely rare ocular extraintestinal manifestations characterized by acute ocular pain that worsens with eye movements and is often accompanied by diplopia. In this case report, we present the case of a 34-year-old woman with a confirmed diagnosis of Crohn's Disease, who experienced two episodes of acute orbital pain exacerbated by ocular movements and diplopia. The diagnosis was established through clinical evaluation and radiologic imaging, with confirmation after a good response to systemic corticosteroids. She responded favorably to systemic corticosteroid therapy on both episodes, and no additional treatment was required. As of now, she remains stable without any ocular sequelae. CONCLUSION: It is important to note that orbital myositis is an uncommon ocular manifestation associated with Crohn's Disease, and prompt recognition and management are crucial to achieve successful outcomes.

Delayed suprachoroidal hemorrhage after Descemet Stripping Automated Endothelial Keratoplasty (DSAEK).

This study, a case series of 2 patients and a literature review, aims to describe the second and third known cases of delayed suprachoroidal hemorrhage after Descemet stripping automated endothelial keratoplasty. The suprachoroidal hemorrhage is defined as the presence of blood in the suprachoroidal space; final visual acuity is rarely greater than 0.1 (decimal scale). Both cases presented had known risk factors: high myopia, previous ocular surgeries, arterial hypertension, and being under anticoagulant therapy. The diagnosis of delayed suprachoroidal hemorrhage was made at the 24-h follow-up visit, as they recalled a sudden and tremendous acute pain hours after surgery. Both cases were drained through a scleral approach. Delayed suprachoroidal hemorrhage is a rare but devastating consequence that can occur after Descemet stripping automated endothelial keratoplasty. Awareness of the most critical risk factors allows for early identification, which is of paramount importance for the prognosis of these patients.
