Choroidal congestion after trabeculectomy
No full textTo report a case of choroidal congestion after trabeculectomy. This is a retrospective case report. An 85-year-old male with advanced open-angle glaucoma underwent trabeculectomy in both eyes and during follow-up he complained visual impairment in the right eye. Thus Spectral-domain Optical Coherence Tomography (OCT) was performed and showed choroidal congestion in one eye after one month from the surgery together with a decrease of visual acuity. Symptoms and exam findings resolved with systemic steroids after 6-month follow-up. OCT is essential for detecting choroidal congestion. This finding can be a possible complication after trabeculectomy and can benefit from steroid treatment
Bilateral Choroidal Osteomas in an Elderly Woman: A Case Report
No full textChoroidal osteoma is a rare clinical entity of unknown etiology. It is a benign ossifying tumor characterized by mature bone replacing choroid. It typically affects young females, unilaterally. Vision loss occurs mainly due to photoreceptor degeneration secondary to decalcification and/or development of choroidal neovascularization, especially if located near the macular area. We present a case of an old woman with bilateral choroidal osteomas identified incidentally. An 84-year-old Caucasian woman who was asymptomatic, without clinical features suggestive of choroidal osteoma, was referred to our hospital for a follow-up visit. On the fundus examination, both eyes showed a suspected lesion. B-scan ultrasound demonstrated bilateral highly reflective calcified lesions within the choroid, with an evident cone of shadow, suggestive of choroidal osteoma. Further investigations have performed to confirm the diagnosis. Although the literature reports a more common one-sidedness and typical manifestation of choroidal osteoma in the teenage years, our case report refers to bilateral choroidal osteomas in an elderly woman
Space and the nation: three texts on Aldo Rossi
No full textIn this paper the spatial dimensions of political practice and the historical dimensions of architectural practice are examined. The author argues that these two practices intersect when, in the life of a city and a nation, time is transformed into space. The productivity of death in this regard is explored. In developing this argument, reference is made to the works and writings of Regis Debray and Aldo Rossi, as well as events in the recent political history of South Africa

Evaluation of a Free Public Smartphone Application to Detect Leukocoria in High-Risk Children Aged 1 to 6 Years
No full textPurpose: To determine whether a white-eye detector smartphone application (app) can be used as a screening tool to detect early signs of leukocoria in a clinical practice.Methods: A prospective, single-visit study of children aged 1 to 6 years presenting to the University Eye Clinic of Genova for a complete pediatric ophthalmologic examination was conducted. All children who met the enrollment criteria were screened by an orthoptist with the CRADLE (Computer Assisted Detector of Leukocoria) smartphone app for an iPhone operating system (iOS) (iPhone 7; Apple, Cupertino, CA). Cycloplegic retinoscopy and fundus examination were performed 30 minutes after one to two drops of a pediatric combination drop, comprising tropicamide 1% and phenylephrine 2.5%, were instilled. A comparison between the two methods yielded sensitivity, specificity, and negative likelihood ratio values.Results: A total of 244 eyes of 122 children were included in the study. Nine eyes of 244 (3.6%) had leukocoria evaluable by penlight caused by amblyogenic cataract, 1 (0.4%) patient had retinopathy of prematurity stage 5, and 3 (1.2%) patients had retinoblastoma. The sensitivity of the white-eye detector app was 15.38% (95% confidence interval [CI]: 1.92% to 45.45%), the specificity was 100% (95% CI: 98.48% to 100.00%), and the negative likelihood ratio was 0.85 (95% CI: 0.67 to 1.07).Conclusions: A smartphone photoscreening app able to detect leukocoria may provide valuable support for children's parents. However, it cannot be considered an alternative to the ophthalmoscope for children

The utility of an artificial substitute to improve corneal sensitivity in glaucomatous patients on chronic therapy with prostaglandin analogs
No full textPurpose: To evaluate whether a tear substitute can improve corneal subepithelial nerve plexus and corneal sensitivity in glaucomatous patients. Methods: This study was prospective, longitudinal, and single arm. Twenty glaucomatous patients were recruited. All the patients were treated with a prostaglandin analog with preservative for at least 1 year. Preservative-free artificial tears (0.5% tamarind seed polysaccharide 0.5® eye drops single-dose preservative free [Oftagen]) were prescribed thrice per day. The participants were subjected to clinical and instrumental evaluation at baseline (T0), after 1 month (T1) and after 3 months (T3) of treatment. All patients were examined with a digital corneal confocal laser-scanning microscope (HRT II Rostock Cornea Module; Heidelberg Engineering GmbH) and Cochet-Bonnet corneal esthesiometer. Results: After the artificial substitute, corneal and conjunctival sensitivity significantly (P<0.001) improved at T1 and T3 compared to the baseline. A significant correlation was found between break-up time and both central corneal sensitivity and the number of fibers. Conclusion: The use of a preservative-free artificial substitute in association with a topical therapy with chronic preservative could increase the compliance of patients
