The authors report a case of a 69 year-old woman who developed persistent vertical deviation and diplopia after extracapsular cataract surgery and had a positive past history of thyroid disease. The authors emphasize the need of for detailed orbit propedeutics in order to rule out restrictive strabismus associated with post-facectomy diplopia.

Pilomatrixoma is a rare benign tumor, which usually affects young women in the head and neck region. The eyelid is a common site of the disease, though it is very rare in the tarsal conjunctiva.The pilomatrixoma has clinical pleomorphism, which confuses this disease with other similar conditions. The diagnosis is made by pathological examination in most cases. The treatment is surgical, performed by total excision of the lesion with clear margins and recurrence is very uncommon.We present an unusual case […]

O pilomatricoma é uma neoplasia benigna rara, geralmente acomete mulheres jovens, ocorrendo na região da cabeça e pescoço. A pálpebra é um local comum de aparecimento do pilomatricoma, contudo, seu aparecimento na conjuntiva tarsal é muito raro. O diagnóstico é feito pelo exame anátomo-patológico na maioria dos casos, pois seu pleomorfismo clínico o confunde com outras alterações. O tratamento é cirúrgico, realizado por meio da exérese total da lesão com margens livres. São raros os casos de recidiva. Apresentamos um […]

Topically applied therapy is the most common way to treat ocular diseases, however given the anatomical and physiological constraints of the eye, frequent dosing is required with possible repercussions in terms of patient compliance. Beyond refractive error correction, contact lenses (CLs) have, in the last few decades emerged as a potential ophthalmic drug controlled release system (DCRS). Extensive research is underway to understand how to best modify CLs to increase residence time and bioavailability of drugs within therapeutic levels on […]

A forma mais frequente de aplicação terapêutica em oftalmologia consiste na instilação de gotas oculares, mas dadas as limitações anatómicas e fisiológicas do olho, é necessária dosagem frequente com possível repercussão na adesão do paciente à terapêutica. Nas últimas décadas, as lentes de contacto (CLs) têm surgido como um potencial sistema de libertação controlada de fármacos na superfície ocular (DCRS) para correção do erro refrativo. Está em curso uma extensa investigação para entender a melhor forma de modificar as CLs, […]

From the clinical point of view ophthalmology in Portugal reached levels of quality and excellence that rival with the best reference centers in the world, with very skilled and distinguished professionals. Regarding research and scientific development, although it has been a long way, it seems clear that the scientific production indicators are still below the existing potential and infrastructure in the country […].

Purpose: To determine the safety and efficacy of corneal collagen cross-linking (CXL) for progressive keratoconus in patients aged between 9 and 14 years old. Methods: Sixteen eyes of 11 patients (8 male and 3 female) with progressive keratoconus underwent epithelium-off CXL according to the standard Dresden protocol. Mean follow-up was 26 months (range, 12 to 60 months). Pre- and postoperative examinations included: uncorrected visual acuity (UCVA), best spectacle-corrected visual acuity (BSCVA), corneal topography, tonometry, refraction, corneal pachymetry, and endothelium cell […]

Purpose: The aim of this study is to describe a variation in technique of the frontalis sling surgery with silicone rods and its results, using an alternative needle with similar effectiveness to the Wright needle at a reduced cost. Methods: This was a prospective, interventional, noncomparative study of patients with severe ptosis who underwent surgical correction using a simple and modified frontalis sling surgery technique. Patients were included in this study from January 2012 to January 2014. 23 surgeries were […]
