Efficacy of femtosecond laser for anterior capsulotomy in complex white cataracts.

OBJECTIVE: To determine the advantages and complication rate of capsulotomy performed with femtosecond laser in white complex cataract cases. STUDY DESIGN: Retrospective case series. PARTICIPANTS: Sixteen eyes of 16 patients. METHODS: This was a single-center retrospective review of white cataract surgery cases in which the femtosecond laser (LenSx, Alcon Laboratories, Fortworth, Texas, USA) was used between May 2019 and February 2021. Outcome measures included an assessment of the capsulotomy, identification of tags, surgical time, cumulative dispersed energy (CDE) and postoperative management. RESULTS: Sixteen eyes of 16 patients were included in this study; capsule tags occurred in six patients (37.5%). In 2 patients, the capsule presented small adhesions that were identified and removed. One patient presented a very significant contraction of the anterior capsule with an incomplete cut zone of 2 to 4hours. In a patient with nystagmus, the capsulotomy was performed without complications under peribulbar anesthesia. CONCLUSIONS: The femtosecond laser permitted capsulotomies of better shape, size and regularity in complex cases of white cataract and in combination with conditions such as nystagmus and prior corneal transplantation. The microadhesions and untreated areas were identified with trypan blue, which is essential to use in these cases to avoid associated complications.

Tamoxifen maculopathy: The importance of screening and long follow-up.

We report a case of a patient treated with tamoxifen 20mg daily as hormone therapy for breast cancer. On regular ophthalmological follow-up, tamoxifen maculopathy was detected on SD-OCT (Spectral Domain Optic Coherence Tomography, Carl Zeiss Meditec®), so the medication was discontinued. Despite discontinuation of the medication, the maculopathy progressed over time. We have been following our patient for seven years. Tamoxifen may produce a toxic maculopathy which may progress despite discontinuation of the medication. We consider our case interesting, given the lengthy follow-up of the patient with sequential SD-OCT images. To the best of our knowledge, our case represents the longest follow-up period for a patient with tamoxifen maculopathy. Moreover, we would like to stress the importance of screening in asymptomatic patients on this medication, in order to detect early pathological signs.

Fotofobia y dolor neuropático en el síndrome de Sudeck / Photophobia and neuropathic pain in Sudecks síndrome

Presentamos a un paciente de 14 años diagnosticado de síndrome de Sudeck secundario a traumatismo no complicado del pie, derivado a nuestro servicio por disminución de la agudeza visual junto con fotofobia y dolor ocular intenso no correlacionado con los hallazgos exploratorios. El síndrome de Sudeck es una enfermedad inflamatoria neuropática idiopática caracterizada por un dolor que es desproporcionado al evento lesivo que lo origina y que puede generalizarse. Recientemente se ha descrito una nueva enfermedad, el dolor ocular neuropático, caracterizado por un dolor exagerado donde los signos clínicos no se correlacionan con el dolor. En nuestro caso al generalizarse el dolor, generó fotofobia y dolor neuropático ocular muy intenso, que creemos que puede ser la causa de la disminución visual que presenta nuestro paciente. Proponemos que el síndrome de Sudeck entre a formar parte del diagnóstico diferencial del dolor ocular neuropático

The case is presented of a 14 year-old patient diagnosed with Sudeck's syndrome secondary to uneventful foot trauma. The patient complained of decreased visual acuity along with photophobia and intense ocular pain not correlated with the exploratory findings. Sudeck's syndrome is an idiopathic neuropathic inflammatory disease characterised by disproportionate pain, unrelated to a previous traumatic event, which can evolve to severe and generalised pain. A new explanation has recently described this as "neuropathic eye pain" for those patients with severe eye pain that do not correlate with clinical signs. In the case presented here, the pain became widespread and led to photophobia and very intense ocular neuropathic pain. It is believed that this was the cause of the visual decrease presented by this patient. It is proposed that the Sudeck syndrome should become part of the differential diagnosis of neuropathic eye pain
