AVASCULAR OVERHANGING BLEB REDUCTION WITH MODIFIED SUTURELESS TECHNIQUE.

A late postoperative trabeculectomy complication could be the overhanging bleb, especially when antimetabolites are used. It can be associated with hypotony, foreign body sensation, dellen, and visual compromise. We report a case of an avascular overhanging bleb successfully reduced with a modified sutureless technique. Nine years before, our patient had trabeculectomy using mitomycin C. After the surgery, the intraocular pressure was correct, without progression in the visual field, but on slit-lamp examination, a large avascular overhanging bleb was noted. Partial excision was performed with dissection from the cornea, overhanging conjunctival trimming, leakage checking and Bandage Contact lens placement. Topical antibiotic and steroid treatment was administered for three weeks. The excised conjunctival histopathology showed avascular metaplastic epithelium. Six months after the surgery, the patient's visual acuity improved, with intraocular pressure of 12 mm Hg and a Seidel negative asymptomatic bleb. In conclusion, this less invasive technique preserves better bleb function without ripping the surrounding ischemic tissue. The procedure is safe and easy to perform, with less surgical time and fast recovery.

The GenoDiabMar Registry: A Collaborative Research Platform of Type 2 Diabetes Patients.

The GenoDiabMar registry is a prospective study that aims to provide data on demographic, biochemical, and clinical changes in type 2 diabetic (T2D) patients attending real medical outpatient consultations. This registry is also used to find new biomarkers related to the micro- and macrovascular complications of T2D, with a particular focus on diabetic nephropathy. With this purpose, longitudinal serum and urine samples, DNA banking, and data on 227 metabolomics profiles, 77 immunoglobulin G glycomics traits, and other emerging biomarkers were recorded in this cohort. In this study, we show a detailed longitudinal description of the clinical and analytical parameters of this registry, with a special focus on the progress of renal function and cardiovascular events. The main objective is to analyze whether there are differential risk factors for renal function deterioration between sexes, as well as to analyze cardiovascular events and mortality in this population. In total, 650 patients with a median age of 69 (14) with different grades of chronic kidney disease­G1−G2 (eGFR > 90−60 mL/min/1.73 m2) 50.3%, G3 (eGFR; 59−30 mL/min/1.73 m2) 31.4%, G4 (eGFR; 29−15 mL/min/1.73 m2) 10.8%, and G5 (eGFR < 15 mL/min/1.73 m2) 7.5%­were followed up for 4.7 (0.65) years. Regardless of albuminuria, women lost 0.93 (0.40−1.46) fewer glomerular filtration units per year than men. A total of 17% of the participants experienced rapid deterioration of renal function, 75.2% of whom were men, with differential risk factors between sexes­severe macroalbuminuria > 300 mg/g for men OR [IQ] 2.40 [1.29:4.44] and concomitant peripheral vascular disease 3.32 [1.10:9.57] for women. Overall mortality of 23% was detected (38% of which was due to cardiovascular etiology). We showed that kidney function declined faster in men, with different risk factors compared to women. Patients with T2D and kidney involvement have very high mortality and an important cardiovascular burden. This cohort is proposed as a great tool for scientific collaboration for studies, whether they are focused on T2D, or whether they are interested in comparing differential markers between diabetic and non-diabetic populations.

Diagnostic Accuracy and Detection Rate of Glaucoma Screening with Optic Disk Photos, Optical Coherence Tomography Images, and Telemedicine.

PURPOSE: The aim of this study was to evaluate the diagnostic accuracy of optical coherence tomography (OCT) and retinography in the detection of glaucoma through a telemedicine program. METHODS: A population-based sample of 4113 persons was randomly selected. The screening examination included a fundus photograph and OCT images. Images were evaluated on a deferred basis. All participants were then invited to a complete glaucoma examination, including gonioscopy, visual field, and dilated fundus examination. The detection rate, sensitivity, specificity, and positive and negative predictive values were calculated. RESULTS: We screened 1006 persons. Of these, 201 (19.9%) were classified as glaucoma suspects; 20.4% were identified only by retinographs, 11.9% only by OCT images, and 46.3% by both. On ophthalmic examination at the hospital (n = 481), confirmed glaucoma was found in 58 (12.1%), probable glaucoma in 76 (15.8%), and ocular hypertension in 10 (2.1%), and no evidence of glaucoma was found in 337 (70.0%). The detection rate for confirmed or probable glaucoma was 9.2%. Sensitivity ranged from 69.4% to 86.2% and specificity from 82.1% to 97.4%, depending on the definition applied. CONCLUSIONS: The combination of OCT images and fundus photographs yielded a detection rate of 9.2% in a population-based screening program with moderate sensitivity, high specificity, and predictive values of 84-96%.

Idiopathic juxtapapillary polypoidal choroidal vasculopathy in the papillomacular bundle: treatment with photodynamic therapy: two years follow-up.

PURPOSE: To evaluate the efficacy of photodynamic therapy (PDT) in a patient with juxtapapillary idiopathic polypoidal choroidal vasculopathy (IPCV) in the papillomacular bundle. METHODS: One session of PDT using a spot size with diameter of 1000 µm in the center of the juxtapapillary lesion was applied. PATIENT: A 75-year-old woman with decreased vision (20/80) in her right eye over a period of 1 year. RESULTS: After a follow-up of 2 years, the best-corrected visual acuity was 20/32, the lesion remained sclerosed, and lipids have disappeared. CONCLUSION: PDT represented a good treatment for this patient with juxtapapillary IPCV.
