RESUMEN

PURPOSE: to underline the importance of optical coherence tomography angiography (OCT-A) in the diagnosis, assessment of final visual outcome and better understanding of the Purtscher like retinopathy, as well as to emphasize on performing an ophthalmologic evaluation in all patients with systemic lupus erythematosus, as eye involvement is closely related with disease activity. METHODS: case report. Ophthalmologic multimodal imaging assessment of a patient short after experiencing a systemic lupus erythematosus severe outset. RESULTS: fundus examination revealed multiple cotton-wool exudates and sharp defined intraretinal white flecken lesions, concentrated in the posterior pole, which along macular edema and the context of lupus disease led to the diagnosis of Purtscher like retinopathy, raising concern about underlying disease activity. OCT-A evidenced ischemic affront in the superficial and deep vascular plexuses but also at choroidal level, preconizing a poor visual outcome. Precapillary retinal vascular stops and choroid lobular ischemic images, with a honey comb configuration in the latter, were of note. Six months after initial consultation, previously displayed ischemic images gave rise to retinal and choroidal atrophy translated into counting fingers best corrected visual acuity with the posterior ensue of retina neovascularization. CONCLUSIONS: This case proves ophthalmologic evaluation mandatory for all patients suffering from lupus and reveals OCT-A as an imaging tool of great value in the assessment of Purtscher retinopathy. To our knowledge, this would be the first report of a SLE Purtscher-like retinopathy characterized by OCT-A, matching graphically and unprecedently vascular micro-embolism stops and ischemic areas, seen as void signals, with the pathognomonic Purtscher flecken, and Paracentral Acute Middle Maculopathy (PAMM) lesions.

RESUMEN

PURPOSE: To assess the risk for capsular rupture during routine phacoemulsification in patients with a history of anti-VEGF injections and other possible risk modifiers such as treatment patterns, type of anti-VEGF agent, and experience of the surgeon, among others. METHODS: This study reviewed the medical records of 11,129 patients from 7 different hospitals in 5 countries. The study included 939 patients that underwent routine phacoemulsification and had a history of anti-VEGF therapy. We excluded patients with known risk factors for capsular rupture, as well as patients with a history of other retinal procedures. The study extracted data regarding general demographics, the number of previous injections, type of anti-VEGF agent, details of cataract surgery, and anti-VEGF treatment patterns. RESULTS: Overall prevalence of posterior capsular rupture: 7.45% (95% CI: 5.9-9.32%). The mean number of injections per patient was 3.37 ± 2.8. More than 50% of the patients received their last anti-VEGF injection within three months before cataract surgery. The complication rate during intravitreal injections was 1.07%. In the univariate analysis, the experience of the cataract surgeon (inexperience surgeons; OR: 2.93) and the history of prior anti-VEGF therapy (OR: 1.77) were significant risk indicators for PCR (p < 0.05). However, after controlling for age in the multivariate analysis, the trend did not reach a statistical significance. CONCLUSION: The risk for capsular rupture is higher in patients with a history of intravitreal anti-VEGF injections.

RESUMEN

Corneal dellen appeared as a complication after perilimbal conjunctival papilloma dissection in a six-year-old patient. Our purpose was to describe the use of plasma rich in growth factors (PRGF) fibrin membrane in covering the corneal defect after conventional medical treatment failure. PRGF fibrin membrane is an interesting therapeutical option to consider not only in adult patients, but also in children.

RESUMEN

Our aim is to describe clinical and optical coherence tomographic features of acute paraneoplastic focal outer retinitis associated with optic neuropathy in a patient diagnosed with small cell lung carcinoma. Bilateral focal outer retinitis, bilateral optic disc oedema and vitritis were identified in a patient with progressive bilateral visual loss and ataxia. Spectral domain optical coherence tomography (SD-OCT) revealed various extents of granular hyperreflectivity and atrophy of the macular outer retinal layers. Serum and cerebrospinal fluid positivity for anti-CRMP5, anti-HU and anti-amphiphysin antibodies intensified the search for an underlying malignancy, and a small cell lung carcinoma (SCLC) was finally diagnosed. Local and oral steroids along with systemic chemotherapy and radiotherapy achieved cancer remission and partial recovery from the ophthalmic manifestations. Focal outer retinitis associated with optic disc oedema and antibody positivity facilitated the diagnosis of SCLC in a localized stage. SD-OCT allowed the characterization of this entity, expanding the spectrum of paraneoplastic ophthalmological syndromes.

RESUMEN

SIGNIFICANCE: Use of anterior segment optical coherence tomography (OCT) is reported, exploring its advantages over other examination techniques. PURPOSE: The purpose of this study was to report a case in which anterior segment OCT was used to evaluate the presence of intraocular bodies after corneal perforation. CASE REPORT: A 33-year-old man was referred to our ophthalmology department after traumatic ocular injury. Swept-source anterior segment was carried out showing corneal perforation and anterior lens capsule rupture. CONCLUSIONS: Evaluating the integrity of posterior capsule and iris after traumatic ocular injury with corneal perforation using anterior segment OCT is a valuable tool to rule out the presence of intraocular foreign bodies without contact and without using radiating imaging techniques.

RESUMEN

PURPOSE: There is no established therapy for exudative-hemorrhagic complications in primary retinal arteriolar macroaneurysm (RAM). METHODS: Retrospective multicenter interventional study of anti-vascular endothelial growth factor in symptomatic RAMs. Central macular thickness in µm and best-corrected visual acuity in logMar were correlated with the RAM size and distance to the macula. Statistical analyses were performed using paired comparisons and Pearson correlation. RESULTS: Thirty-two eyes (32 patients) were treated with a mean of 2.7 injections over a mean follow-up of 16.6 months. Initial best-corrected visual acuity correlated with the RAM size and distance to the macula (P = 0.02). Central macular thickness decreased by 131,180, and 211 µm at 1, 2, and 3 months after the first injection (P < 0.001). Best-corrected visual acuity improved by 0.47 and 0.38 Early Treatment Diabetic Retinopathy Study lines at 2 and 3 months (P = 0.005). Anti-vascular endothelial growth factor response correlated with the RAM size (P = 0.04) and the distance to the macula (P = 0.009). CONCLUSION: Symptomatic RAMs can be treated successfully with anti-vascular endothelial growth factor injections, leading to a decrease in macular edema.

RESUMEN

Arteriovenous fistulas (AVFs) are abnormal shunts between the arterial and venous vascular systems. These usually produce ocular pain, increased intraocular pressure (IOP), and diplopia. Less frequently, they may cause retinal changes with visual impairment. Our purpose is to illustrate different retinal manifestations of AVF. We report the multimodal imaging study of three cases with retinal changes due to AVF, showing neurosensory retinal detachment, macular oedema, and macular ischemia. In conclusion, AVF may appear with different ophthalmic alterations. While usually increased IOP and diplopia are our main concerns, retinal study is mandatory, since a myriad of morphologic abnormalities might be present.
