Surgical options for the correction of presbyopia / 中华实验眼科杂志

Presbyopia is an age-related eye condition,and its most prominent sign is the reduction in the amplitude of accommodation,resulting in the disability to modify the focus from far to near of the eyes.Surgical therapy of presbyopia still remain great challenge for refractive surgeons.Surgical strategies of presbyopia include extraocular (corneal or scleral) and intraocular procedures,such as excimer laser surgery,conductive keratoplasty,INTRACOR,corneal inlays,multiple types of muhi-focal or accommodating intraocular lens,laser-assisted presbyopia reversal,scleral expansion bands,etc.Each procedure owns its unique advantages and disadvantages.This review attempted to address the surgical options available and likely to be available in the near future and discuss the key problems in presbyopia procedures.

Case report: pneumatic retinopexy for the treatment of progressive retinal detachment in senile retinoschisis / Relato de caso: retinopexia pneumática no tratamento do descolamento de retina associado à retinosquise senil

Retinoschisis is an abnormal separation of the retinal layers and is asymptomatic in most cases. Enlargement of the area of retinoschisis and retinal tear and detachment are possible complications of the disease, and the treatment of retinoschisis is controversial. In this case report, we present a case of retinal detachment associated with senile retinoschisis in which pneumatic retinopexy was chosen as the treatment of choice and was performed successfully in one of the eyes. After a literature review on retinoschisis and pneumatic retinopexy for the treatment of associated retinal detachment, we found only one case that was successfully treated without drainage of subretinal fluid, using air as the filler. However, no previous reports have been found in the literature on the effectiveness of pneumatic retinopexy using C3F8 as the sole treatment for progressive retinal detachment in senile retinoschisis.

Retinosquise significa uma separação anormal das camadas da retina e, na maioria dos casos, é assintomática. Aumento da área de retinosquise, roturas e descolamento de retina são possíveis complicações da doença, sendo seus tratamentos controversos. Nesse relato, apresentamos um caso de descolamento de retina associado à retinosquise senil em que foi optado pela retinopexia pneumática como primeiro tratamento, com sucesso em um dos olhos tratados. Revisada literatura sobre retinosquises e retinopexia pneumática para tratamento de descolamento de retina associado, foi encontrado apenas um caso tratado com sucesso, sem drenagem de líquido sub-retiniano, utilizando-se ar como agente tamponante. Não existem relatos na literatura de retinopexia pneumática efetiva utilizando C3F8 como tratamento único para descolamento de retina progressivo na retinosquise senil.

Fibro-histiocitoma maligno da pálpebra: relato de caso / Malignant fibrous histiocytoma of the eyelid: case report

Os fibro-histiocitomas representam 1 por cento das massas orbitárias e podem ser histologicamente classificados em benignos, localmente agressivos e malignos - os últimos representando aproximadamente 11 por cento do total. Nesse estudo, os autores descrevem um caso raro de fibro-histiocitoma maligno de pálpebra, ressaltando as características clínicas e histopatológicas desta neoplasia.

Fibrous histiocytomas represent 1 percent of all orbital masses and may be classified into benign, locally aggressive and malignant - these representing nearly 11 percent of the total. In this study, the authors describe an unusual case of malignant fibrous histiocytoma of the eyelid, discussing clinical and histological features of this neoplasm.
