Evaluation of macular integrity, after retinal detachment surgery, using MAIA microperimetry.

BACKGROUND AND OBJECTIVE: To describe visual function, macular integrity, and fixation stability using MAIA microperimetry (macular integrity assessment) after retinal detachment surgery. Evaluate if there are statistically significant differences between surgical approaches. MATERIALS AND METHODS: A prospective, comparative, interventional study was conducted, recruiting a total of 21 patients with rhegmatogenous retinal detachment and macula-off. Eleven patients underwent surgery using pars plana vitrectomy (PPV), and 10 patients underwent scleral buckle surgery. Clinical examinations and optical coherence tomography (OCT) were performed post-surgery. MAIA microperimetry was conducted at 6 months. RESULTS: Best-corrected visual acuity (BCVA) and the number of letters read improved over time in the operated eye but did not reach the level of the control eye (p = 0.001). No significant differences were found between the two surgical approaches in BCVA (p = 0.230) or the number of letters read (p = 0.608). Macular integrity in the operated eye did not match that of the control eye in both procedures (p = 0.05). No differences were detected between the two surgeries, either in macular integrity (p = 0.512) or fixation stability (p = 0.835). CONCLUSIONS: Following retinal detachment surgery, a decrease in BCVA and the number of letters read occurs, which does not reach the level of the control eye. No significant differences were observed between the two surgical approaches. Macular integrity in the operated eye does not match that of the control eye.

Queratouveítis y conjuntivitis causadas por Euphorbia ingens. Revisión de un caso / Keratouveitis and conjunctivitis caused by Euphorbia ingens: A case review

Euphorbia ingens es una planta ubicua, que contiene una savia lechosa. Puede accidentalmente dañar los ojos de los humanos por su naturaleza cáustica, causando conjuntivitis, queratitis, uveítis, estafiloma anterior y cicatrización corneal en pacientes no tratados. Presentamos el caso de un paciente cuyo ojo entró en contacto con esta savia lechosa, causándole conjuntivitis, defecto epitelial corneal y uveítis. Después de un tratamiento intensivo, su ojo se recuperó completamente. Recomendamos el uso de guantes y gafas protectoras antes de manipular este tipo de plantas (AU)

Euphorbia ingens is a ubiquitous plant who has a milky sap. It can accidentally harm human's eye by its caustic nature, causing conjunctivitis, keratitis, uveitis, anterior staphyloma and corneal scarring in untreated patients. We present the case of a patient whose eye came into contact with the milky sap. He suffered conjunctivitis, corneal epithelial defect and uveitis. After intensive treatment, his eye made a complete recovery. We recommend gloves and protecting glasses before handling these types of plants (AU)

Glaucoma neovascular causado por metástasis de carcinoma microcítico de pulmón. Presentación de un caso / Neovascular glaucoma caused by small-cell lung cancer iris metastasis: A case presentation

El carcinoma microcítico de pulmón puede afectar al ojo directamente mediante proliferación metastásica o indirectamente a través de síndromes paraneoplásicos. La coroides es el lugar más afectado entre las metástasis uveales; no obstante, el iris puede estar envuelto en una proporción pequeña de casos (<10%). Visión borrosa, dolor, hiperemia, fotofobia, glaucoma, hipema o defectos en el campo visual pueden originarse por la afectación metastásica. La mediana de supervivencia en pacientes con metástasis iridianas es de 4 meses. El glaucoma secundario que se origina puede ser manejado con tratamiento tópico y oral, ciclo fotoablación transescleral, trabeculoplastia con láser, anti-VEGF, MIGS, cirugía filtrante o enucleación. Se presenta un caso único que desarrolló un cáncer microcítico de pulmón primario con metástasis iridianas. Las metástasis provocaron un cierre angular, refractario al tratamiento tópico. Se realizó radioterapia local para conseguir una respuesta local (AU)

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 (AU)
