Neovascular glaucoma caused by small-cell lung cancer iris metastasis: A case presentation.

Small-cell lung cancer may directly affect the eye by metastatic proliferation or indirectly by paraneoplastic syndromes. The choroid is the most common site for uveal metastasis (90%); however, the iris can be involved in a smaller proportion of cases (incidence <10%). Blurred vision, pain, redness, photophobia, glaucoma, hyphema and visual field defects can arise from this metastatic involvement. The median survival time for patients with iris metastasis is reported to be 4 months. Secondary glaucoma can be managed with topical and oral treatment, transscleral cyclophotocoagulation, laser trabeculoplasty, anti-VEGF, Minimally Invasive Glaucoma Surgery (MIGS), filtering surgery, shunting surgery or enucleation. A case of primary small-cell lung cancer with iris metastasis is presented. The metastases produced an angle-closure glaucoma, which was refractory to topical treatment. Local radiotherapy was administered, obtaining a good local response.

Stargardt disease: A clinical case report of two sisters with different clinical development.

The purpose of this article is to describe the clinical manifestations and complementary diagnostic tests of two sisters aged 26 and 31 with a diagnosis of Stargardt's disease. One of them presented with an initial visual acuity of 0.7 and showed a progressive central visual loss due to the atrophy of the external layers of the retina in the subfoveal region. She was recruited to participate in a clinical trial of Avancincaptad Pegol (Zimura®), an inhibitor of C5 of the complement's system. The other sister remained asymptomatic with a visual acuity of 1 in both eyes. In both cases white-yellow pisciform lesions were observed on the posterior pole. Although there is no curative treatment for this disease, there are many lines of investigation on this topic. The clinical and diagnostic tests can confirm the disease, and provide patients with an accurate prognosis.

Association between maxillary sinus pathology and odontogenic lesions in patients evaluated by cone beam computed tomography. A systematic review and meta-analysis.

BACKGROUND: A study is made of the association between maxillary sinus pathology and odontogenic lesions in patients evaluated with cone beam computed tomography. MATERIAL AND METHODS: A literature search was made in five databases and OpenGrey. Methodological assessment was carried out using the Newcastle-Ottawa tool for observational studies. The random-effects model was used for the meta-analysis. RESULTS: Twenty-one studies were included in the qualitative review and 6 in the meta-analysis. Most presented moderate or low risk of bias. The periodontal disease showed to be associated with the thickening of the sinus membrane (TSM). Mucous retention cysts and opacities were reported in few studies. The presence of periapical lesions (PALs) was significantly associated to TSM (OR=2.43 (95%CI:1.71-3.46); I2=34.5%) and to odontogenic maxillary sinusitis (OMS) (OR=1.77 (95%CI: 1.20-2.61); I2=35.5%). CONCLUSIONS: The presence of PALs increases the probability of TSM and OMS up to 2.4-fold and 1.7-fold respectively. The risk differences suggests that about 58 and 37 of out every 100 maxillary sinuses having antral teeth with PALs are associated with an increased risk TSM and OMS respectively. The meta-evidence obtained in this study was of moderate certainty, and although the magnitude of the observed associations may vary, their direction in favor sinus disorders appearance, would not change as a result.
