Use of semisynthetic dura mater substitute as a patch graft for prosthesis extrusion in anophthalmic socket. / Uso de sustituto semisintético de duramadre como injerto tras extrusión de prótesis en una cavidad anoftálmica.

We present a case report of a three-year old patient diagnosed with retinoblastoma in her left eye. The course of the disease made enucleation of the latter eye and a prosthesis implant necessary. Two years after surgery, partial prosthesis extrusion occurred and a semisynthetic dura mater substitute was used as a patch graft to cover the defect. To our knowledge, semisynthetic dura mater substitutes' use in this scenario has not been previously reported.

Delayed infectious keratitis in a patient with radial keratotomy and floppy eyelid syndrome treated with simple interrupted stitches. / Queratitis infecciosa tardía en paciente con queratotomía radial y síndrome del párpado flácido tratado con puntos sueltos.

A 55-year-old male presented with an infectious keratitis in his left eye, affecting one of the incisions of the radial keratotomy he had undergone thirty-four years ago. Suturing the incision with two simple interrupted stitches was key to the resolution of the infection. Floppy eyelid syndrome was also found in this patient. Could this act as a risk factor for infectious keratitis in radial keratotomy? To our knowledge, this is the first reported case describing the association between both conditions, and the second reported case where sutures have been used as an adjuvant treatment in these types of cases.

Coexistent central retinal vein and artery occlusion in a patient with psoriasis receiving ustekinumab. / Oclusión coexistente de vena y arteria central de la retina en un paciente con psoriasis en tratamiento con ustekinumab.

A 44 year-old Caucasian male with a history of plaque psoriasis currently being treated with ustekinumab presented with sudden loss of vision in his left eye. Fundus examination showed central retinal vein occlusion coexisting with central retinal artery occlusion. Posterior examination revealed mild polycythemia, being the underlying cause unknown.

Hypertensive choroidopathy and adrenal carcinoma: A new association. / Coroidopatía hipertensiva y carcinoma adrenal: una nueva asociación.

A 17 year-old Caucasian female presented with decreased vision, with no other symptoms reported at that time. Ophthalmological examination revealed typical signs of hypertensive choroidopathy, Elschnig spots, and Siegrist streaks. Further medical examination found high blood pressure (220/155mmHg), with a metastatic hormone-secreting adrenal carcinoma being the underlying cause of these alterations. To our knowledge, this is the first reported case of hypertensive choroidopathy associated with adrenal carcinoma.
