RESUMEN
PURPOSE: To analyze the efficacy, safety and cost-effectiveness of adjuvant therapy with 5-fluorouracil (5-FU) compared to interferon α-2b (IFNα-2b) after surgery in ocular surface squamous neoplasia (OSSN). METHODS: Retrospective study that included patients diagnosed with OSSN, who underwent surgical excision followed by adjuvant therapy with IFN α-2b (Group A) or 5-FU (Group B), in a tertial referral hospital. Clinical data collected included: demographics, risk factors, appearance, size and location of the lesions, slit-lamp examination, anterior segment optical coherence tomography, iconography and histological classification of subtypes of OSSN. Costs derived from surgery and adjuvant therapy were noted. Resolution of the lesion, recurrences and adverse events were studied. Cost-effectiveness analysis was performed with the incremental cost-effectiveness index (CEI). RESULTS: 54 cases of 54 patients were included, with a mean age of 74.4 years (range 28-109). 30 were male (55.6%), and predominantly Caucasian (79.6%). The main risk factor was prolonged sun exposure (79.6%). Leukoplakic appearance (48.1%), location in bulbar conjunctiva (48.2%) and T3 (46.3%) stage were the most common clinical features. Histologically, the percentage of CIN I, CIN II, CIN III and SCC were 25.9%, 29.6%, 40.7% and 3.7%, respectively. Complete resolution was obtained in 74.1% and tolerance was overall positive. The cost was significantly higher for IFNα (1025 ± 130.68) compared to 5-FU (165.57 ± 45.85 ) (p 0.001). The CEI was - 247.14. CONCLUSIONS: Both 5-FU and IFN α-2b are effective and present a good security profile as adjuvant therapies after surgery in OSSN. Although presenting slightly more ocular complications, 5-FU can be considered more cost-effective than IFN α-2b.

PURPOSE: To describe the different phenotypes of syphilitic chorioretinitis (SCR) and its clinical features in multimodal imaging (MI). METHODS: Complete ophthalmological examination and MI including spectral domain optic coherence tomography (SD-OCT), fundus autofluorescence (FAF) and fluorescein angiography (FA) were performed at diagnosis and during follow-up in patients diagnosed with SCR. RESULTS: 17 eyes of 10 patients were included. Clinical phenotypes included acute syphilitic posterior placoid chorioretinopathy (ASPPC), syphilitic outer retinitis (SOR) and punctate inner retinitis (PIR). Disruption of outer retinal layers were visible in all patients in SD-OCT. Inner retinal layers were only affected in PIR. FAF revealed macular hyperautofluorescence in all patients. FA showed maintained hyperfluorescence in ASPPC and SOR. CONCLUSIONS: ASPPC, SOR and PIR are different phenotypes of syphilitic chorioretinitis and present common features in SD-OCT and FAF. MI provides useful information to help the clinician during diagnosis and follow-up of these entities.

PURPOSE: To report visual, clinical and radiological outcomes of three patients with fibromuscular dysplasia (FMD) that presented different ocular ischemic events, supported by different multimodal imaging. METHODS: A retrospective study including patients who attended a tertiary referral hospital from July 2016 to June 2019 referring acute visual loss and later diagnosed of FMD. Ophthalmological examination included best corrected visual acuity (BCVA), biomicroscopy, fundoscopy, fluorescein angiography (FA), and macular and retinal nerve fiber layer spectral domain optic coherence tomography (SD-OCT). Patients were admitted by the Neurology service, completing the study with blood and cerebrospinal fluid (CSF) test, serology and cultures, cerebral magnetic resonance angiography (angioMRI), and arteriography. RESULTS: Three patients were included; one male and second females. All referred unilateral acute visual loss, with BCVA of counting fingers or hand-motion. Relative afferent pupilar defect was present in all patients. Two patients associated neurological focal signs and one had chronic hypertension. Fundoscopy revealed hemorrhages and exudates in all patients, and the typical sign of "string-of-beads" in one. FA showed dye filling delay and macular and peripheral hypofluorescence. SD-OCT revealed acute and chronic retinal ischemic signs. Blood and CSF tests, serologies and cultures resulted negative. All presented cerebral vascular involvement, objectified in the cerebral angioMRI or arteriography. CONCLUSIONS: FMD should be considered in cases with unilateral sudden visual loss associated to neurological focal deficits in young patients. The typical "string-of-beads" image is rare in small arteries such as the retinal vasculature. When suspected, a complete ophthalmological examination and cerebral vascular imaging is essential to confirm the diagnosis.

Peripheral ulcerative keratitis (PUK) is a group of corneal disorders that cause peripheral corneal thinning, threatening globe integrity in advance stages. It is usually associated with systemic autoimmune diseases and management is based on local and systemic approaches. We present the case of a 47-year-old man with a previous history of bacterial keratitis in his left eye presenting with 1 month of bilateral ocular pain and redness. At examination, diffuse bilateral globe inflammation with paracentral corneal thinning in his left eye was observed. He was diagnosed with bilateral scleritis and PUK in his left eye. Workup for associated systemic autoimmune disease yielded negative results. The patient was started on pulses of intravenous methylprednisolone followed by oral prednisone failing to achieve sufficient control of the inflammatory syndrome. Subsequently, periodic intravenous cyclophosphamide was administered with a favorable response. A multilayer amniotic membrane graft was applied, but there was rapid melting with reabsorption of the tissue, resulting in extreme corneal thinning at the inferior paracentral cornea. A decentered 8.5-mm superficial anterior lamellar keratoplasty (SALK) was then performed obtaining the donor graft with a femtosecond laser but performing manual trepanation in the recipient. At 12 months, visual and biomicroscopic measures do not show deterioration and inflammation remains under control with oral azathioprine as maintenance regime. The management of PUK includes both systemic immunosuppression and tectonic procedures to preserve the globe integrity. Diverse surgical techniques have been attempted, but no definitive guidelines are available. Decentered large SALK is a simple technique that can yield acceptable visual results.
RESUMEN
Idiopathic orbital inflammation (IOI) is a noninfectious inflammatory disease whose etiology remains unknown. Treatment is focused on reducing inflammation, which becomes challenging in nonresponding cases. We report the case of a 59-year-old woman with refractory IOI that showed a positive response to tocilizumab therapy. The patient was diagnosed with a unilateral sclerosing IOI for 9 years and showed a negative control with previous oral steroids, peribulbar steroid injections, radiotherapy, immunosuppressors, and intravenous rituximab. After the initiation of 8 mg/kg intravenous tocilizumab, a complete reduction of the pain and the orbital inflammation signs was observed and her condition remained stable for the following 6 years under a monthly dose of 4 mg/kg. In recalcitrant IOI cases, tocilizumab could be considered a possible treatment to reduce inflammatory signs and symptoms with positive long-term outcomes as in our case.
RESUMEN
PURPOSE: To report the 5-year outcomes of the first reported case of bilateral Descemet stripping only (DSO) for Fuchs endothelial corneal dystrophy (FECD) at our center. Visual, biomicroscopic, and confocal microscopic findings are described. METHODS: A retrospective case report. RESULTS: A 55-year-old woman with bilateral FECD was referred with decreased visual acuity and blurred vision that interrupted activities of daily living. She underwent sequential 4-mm DSO procedures 6 months apart, with early postoperative results previously reported. Subjective visual symptoms, visual acuity, and corneal edema were analyzed at 1 month, 3 months, 6 months, 12 months, 2 years, 3 years, and 5 years postoperatively. Best corrected visual acuity of 0.0 (logarithm of the minimum angle of resolution) and corneal clearance were achieved in the third month after the procedure. These results have remained stable in the 5-year follow-up period. CONCLUSIONS: Early postoperative results from DSO surgery are encouraging, but questions remain regarding its longevity. Publication of longer-term outcomes such as this is necessary to establish the validity of this procedure as an intervention for FECD.
