Introduction This paper reports the first occurrence of a late internalized flange due to capsular contraction syndrome after undergoing the double-flanged surgical technique. Case Description A 32-year-old woman with Marfan syndrome underwent phacoemulsification using the double-flanged technique in both eyes. Two years postoperatively, a slit lamp examination revealed a capsular bag with anterior phimosis (capsular contraction syndrome) and the external flange internalized. The patient was submitted for a new surgery to re-fixate the capsular bag. The procedure was successfully accomplished. The intraocular lens was centered by the end of the procedure without areas of traction. The patient presented with best corrected visual acuity of 20/25 in both eyes postoperatively. Conclusions This paper recounts a successful re-approach of a late internalized double-flange two years after the first procedure in a patient that developed capsular contraction syndrome.

Wasp stings are considered an ophthalmological emergency as they can be complicated when they occur near the eyelids or especially on the cornea. Due to type I hypersensitivity response, such as epithelial defect, corneal edema, loss of endothelial cells, anterior uveitis, optic neuritis and, therefore, permanent loss of vision due to anterior segment ischemia. It warns that the wasp stinger has a saw-shaped texture, contains toxins that inflame the area where it stings. Due to the immunological and toxic effects of the stinger and its venom infiltrates the cornea. We present the case of a 32-year-old man who presented keratouveitis secondary to a wasp sting in a region of the jungle of Peru. He was treated emergency with intensive steroid therapy to reduce the toxic effects. His follow-up up to 2 months was successful, leaving only a 1 mm central leukoma where the bite occurred, which did not impair his vision.

Descemet's membrane detachment (DMD) is a complication fundamentally associated with cataract surgery, the subclinical presentation being higher than expected. There are many varied treatments, from simple observation to penetrating keratoplasty. We present a case report of a 78-year-old male patient, without comorbidities, who underwent cataract surgery with phacoemulsification plus intraocular lens implantation in the capsular bag of the left eye. During the intraoperative procedure, he presented a DMD (height of 350 um and length of 3 mm in Zone 1 according to the HELP algorithm), managed with adaptive viscoelastic under the soft-shell technique in the same operative act, injection of iso-expansile SF6 (20%) intracameral plus postural positioning for 2 hours carried out 48 hours after surgery plus intensive topical treatment with hypertonic sodium chloride and steroidal anti-inflammatory drugs. At 72 hours after the operation of the application of the gas bubble, he presented with a transparent cornea and a bestcorrected visual acuity of 20/80, which finally for his ophthalmological control at 8 weeks presented definitive resolution of the case in the AS-OCT and with a BCVA of 20/30.

Purpose: To evaluate the results of central pars plana vitrectomy + phacoemulsification + intraocular lens implantation in patients with small eyes, cataract, and narrow chambers. Methods: This prospective study was carried out in 89 eyes of 58 patients undergoing central pars plana vitrectomy + phacoemulsification + IOL implantation in small eyes with cataract at Clínica La Luz Eye Institute in Lima, Peru. Results:The mean best corrected visual acuity (BCVA) was 0.8±0.6 preoperatively, 0.5 ±0.6 at 1 month, 0.3±0.3 at 6 months, 0.1±0.1 at 9 months, and 0.05±0.1 at 1 year, which was statistically significant from the preoperative period to 1 year of follow-up. Mean intraocular pressure was 22.09±2.4 mmHg preoperatively, 14.55±2.9 mmHg at 1 day, 12.94±2.04 mmHg at 1 month, 12.01±1.2 mmHg at 6 months, 12.20±1.9 mmHg at 9 months, and 11.34±1.1 mmHg at 1 year. The reduction in the intraocular pressure from the preoperative control period to the follow-up at 1 year was statistically significant. There was only one complication, a rupture of the posterior capsule, which was quickly resolved. Conclusion:Central pars plana vitrectomy with phacoemulsification is a safe and effective technique to perform in narrow chambers with all types of cataracts, in experienced hands, which can avoid intraoperative complications.

Introducción: El trauma ocular es una de las causas que difieren entre áreas urbanas de un país a otro y entre diferentes clases demográficas o socioeconómicas. Objetivo: Demostrar la evolución y características clínicas del edema de Berlín secundario a trauma ocular cerrado. Materiales y métodos: Se realizó un estudio de caso observacional en un paciente masculino de 11 años que presentó una AVMC 20/20 en OD y cuenta dedos 50 cm en OI posterior a trauma ocular cerrado contuso con objeto romo. Desde el inicio desarrolló una conmoción retiniana asociada a edema de Berlín en OI. Con seguimiento desde 11 de diciembre de 2019 al 27 de enero de 2020. Las variables fueron: agudeza visual mejor corregida, retinografía, tomografía de coherencia óptica de dominio espectral macular. Resultados: Se indicó metilprednisolona 500 mg endovenoso diario por 3 días; prednisona 30 mg oral disminuyendo gradualmente durante 10 días; acetato de prednisolona 1% tópico cada 2 horas, moxifloxacina 0,5% cada 6 horas, ciclopentolato 1% cada 8 horas. 7 semanas después, no hubo mejoría clínica a pesar de medicación, manteniéndose en observación médica con AVMC OD 20/20 y OI cuenta dedos 2 metros. Discusión: Edema de Berlín (commotio retinae) una afección común causada por una lesión contusa en el ojo, suele ser autolimitante y no existe un tratamiento como tal. Conclusión: El trauma ocular cerrado contuso con compromiso retiniano puede causar daño macular como el edema de Berlín, como éste caso que puede condicionar el pronóstico visual a pesar de que mayormente es favorable.
