Multidisciplinary eyelid reconstruction in Barber-Say syndrome: A case report. / Reconstrucción palpebral multidisciplinar en el síndrome de Barber-Say: a propósito de un caso.

Barber-Say syndrome is an unusual dysplasia caused by the mutation of the TWIST2 gene (2q37.3), which encodes a protein that acts at an epigenetic level. The case is presented of a 2-day-old male child in whom ectropion, hypertelorism, hypertrichosis and other dysmorphic features led to the clinical diagnosis of Barber-Say syndrome, which was later confirmed with genetic tests. Around 20 cases have been reported on this syndrome, of which less than half have described the surgical technique, as it represents a surgical challenge. The approach in this case included a lateral tarsorrhaphy and skin grafts taken from the volar surface of the forearm, retroauricular area and supraclavicular fossa, as well as autologous lipografts from the inner side of both thighs for palpebral reconstruction. This is the first case of Barber-Say syndrome in which the use of skin grafts are taken from supraclavicular fossa and forearms.

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.

Ocriplasmin retinopathy: Possible cause of macular hole closure failure. / Retinopatía asociada a ocriplasmina: posible causa de fracaso de cierre de agujero macular.

CASE REPORT: A 53 year-old woman with a stage 2 macular hole received ocriplasmin injection as a first approach. She subsequently underwent pars plana vitrectomy due to enlargement of the hole post-injection. The visual gain following the surgery was minimal despite closure of the hole. This could be explained by outer retina atrophy as a consequence of potential toxic mechanisms related to ocriplasmin. DISCUSSION: Further studies may be warranted to fully understand the impact of ocriplasmin on long-term visual function.

Geographic atrophy: Etiopathogenesis and current therapies. / Atrofia geográfica: etiopatogenia y terapias actuales.

Geographic atrophy is characterized by severe visual deficit whose etiology and pathophysiology are yet to be elucidated. As a working hypothesis, oxidative damage could trigger a chronic inflammation in Bruch's membrane-RPE-choriocapillaris complex, mostly due to complement pathway overactivation. Some individuals with mutations in the complement system and other factors have diminished capacity in the modulation of the inflammatory response, which results in cell damage and waste accumulation. This accumulation of intracellular and extracellular waste products manifests as drusen and pigmentary changes that precede the atrophy of photoreceptors, RPE, choriocapillaris with an ischemic process with decreased choroid flow. All these processes can be detected as tomographic findings and autofluorescence signals that are useful in the evaluation of patients with atrophic AMD, which helps to establish an individualized prognosis. Anti-inflammatory, antioxidant and therapies that decrease the accumulation of toxins for the preservation of the RPE cells and photoreceptors are being investigated in order to slow down the progression of this disease.

Recurrent conjunctival atypical fibroxanthoma in Pigmentosum Xeroderma. / Fibroxantoma atípico conjuntival recurrente en el xeroderma pigmentoso.

CASE REPORT: A 7 year-old boy with Xeroderma Pigmentosum (XP) and who presents a recurrent conjunctival atypical fibroxanthoma after two surgeries. This is the third procedure and the patient is treated with a surgical excision of the tumour and cryotherapy at the surgical bed. Due to the risk of recurrence, topical Mitomycin C 0,02% was added at post-operative care achieving a good clinical outcome. DISCUSSION: Surgical exeresis with cryotherapy and topical Mitomycin C is an effective treatment for a case of an atypical fibroxanthoma with a high potential for recurrence and invasion. An ophthalmologic follow-up is required for these patients, as well as general paediatric care and support aids.

Purtscher-like retinopathy associated with dermatomyositis and hemophagocytic lymphohistiocytosis. / Retinopatía Purtscher-like asociada a dermatomiositis y linfohistiocitosis hemofagocítica.

CASE REPORT: An 11 year-old girl with progressive muscle weakness due to dermatomyositis and hemophagocytic lymphohistiocytosis in which multiple cotton exudates, venous tortuosity and flame haemorrhages are detected in the funduscopic examination, leading to the diagnosis of Purtscher-like retinopathy. DISCUSSION: Purstcher's retinopathy is a microvascular disorder with clinical signs of probable thrombotic origin. Its treatment is controversial, with systemic corticosteroids being the most widespread choice.
