Choroidal vascularity index in pseudoexfoliative glaucoma.

PURPOSE: To evaluate choroidal vascular involvement in pseudoexfoliative glaucoma (PEXG) by applying the choroidal vascularity index (CVI) to optic coherence tomography (OCT) images. METHODS: Seventy-eight eyes from 40 subjects were included the study. Group 1 included healthy eyes (n = 20), group 2 eyes with PEX (n = 16), and group 3 eyes with PEXG (n = 42). OCT imaging of macular and peripapillary regions and retinal nerve fiber layer (RNFL) analyses were performed. CVI was calculated using ImageJ software. RESULTS: The mean age was 64.89 ± 5.8, 71.2 ± 7.8, and 68.24 ± 7.4 years in groups 1, 2, and 3, respectively (p = 0.046). There were no significant differences between the groups in terms of sex (p = 0.777). In macula, mean CVI rates were 66.97 ± 1.9%, 64.23 ± 1.2%, and 64.63 ± 1.6%, and in the peripapillary areas, mean CVI rates were 67.04 ± 1.5%, 65.20 ± 1.5%, and 64.14 ± 2.1% in groups 1, 2, and 3, respectively (group 1 vs. group 2 and 3, p = 0.000; group 2 vs. group 3, p > 0.05). The decrease in average RNFL thickness was statistically significant in group 3 compared to groups 1 and 2. CONCLUSION: CVI could be used to assess choroidal vascular changes in ocular diseases. CVI was found to be reduced in PEX and PEXG, indicating an ocular vascular involvement in pseudoexfoliative process.

Combined Intracapsular Lens Removal and Scleral Fixation of Intraocular Lenses Through the Same Scleral Tunnel in Cases with Severely Dislocated Lenses.

OBJECTIVES: The management of severely dislocated lenses floating in the anterior vitreous is challenging. This study describes the clinical outcome of a surgical approach with intracapsular lens extraction (ICCE) and implantation of a scleral-fixated posterior chamber intraocular lens (SF-IOL) at the same surgical session. METHODS: Records of patients who had severely dislocated lenses were retrospectively reviewed. All included patients had undergone ICCE, followed by implantation of an SF-IOL during the same surgical session through the same scleral tunnel placed 1.5 mm posterior to the limbus. Clinical characteristics of the patients were collected, and surgical videos were watched again to review intraoperative complications. RESULTS: Thirty eyes of 30 patients (mean age, 68±11.1 years, 23 male, 7 female) were included in the study. Twenty-five patients had a history of blunt trauma, and five patients had pseudoexfoliation syndrome. The best-corrected visual acuity of the patient improved significantly after the procedure (p=0.001). The intraocular pressure of the patients remained unchanged (p=0.38). Three patients developed mild IOL dislocation that did not require any intervention. A patient developed transient hypotony, and another developed mild vitreous hemorrhage. These complications improved spontaneously without the need for further intervention. CONCLUSION: Simultaneous removal of dislocated lens and SF-IOL implantation through the same scleral tunnel was a safe and effective procedure for patients with severely dislocated IOLs.

Eruption of impacted permanent teeth after treatment of a dentigerous cyst: a case report.

Dentigerous cysts are the most common developmental odontogenic cysts. It is a benign and asymptomatic intraosseous lesion that affects the bones of the maxillofacial complex, interfering with tooth eruption. Although enucleation is the treatment of choice, marsupialization is the better option for large cysts involving unerupted permanent teeth. The purpose of this article is to report the eruption of impacted permanent mandibular right canine and first and second premolars after marsupialization of an infected dentigerous cyst. Two years after marsupialization and orthodontic treatment, the cyst disappeared and the canine and premolars erupted uneventfully.
