title: Corneal crosslinking efficacy in patients with keratoconus under 18 years of age

description: ABSTRACT Purpose: Keratoconus presents certain specificities in pediatric patients compared with adults. The greatest challenge is because the disease is typically more severe and progresses faster in children. This retrospective study aimed to report crosslinking procedure in patients under 18 years of age and their follow-up for at least 24 months after the procedure. Methods: Overall, 12 eyes from 10 patients were studied and data, such as visual acuity with and without correction, maximum keratometry, corneal thickness, foveal thickness, and endothelial microscopy, were assessed at both preoperative and postoperative visits. Corneal crosslinking was performed in all patients. Results: A tendency toward reduced Kmax and improved Corrected Distance Visual Acuity at all postoperative moments. Only one of the 12 eyes exhibited increased Kmax of more than 1 D during a time frame longer than 12 months. Regarding pachymetry, a tendency for corneal thinning was observed in the first four months after surgery. Conclusion: Encouraging results were obtained regarding the stabilization of the disease, progression, and procedural safety, corroborating to other authors’ findings. The significance of early diagnosis and short-term follow-up were highlighted.

title: Long-term results of visual function in posterior uveal melanoma patients treated with I125 episcleral brachytherapy in a Spanish referral Ocular Oncology Unit

description: ABSTRACT Purposes: We analyzed patient, tumor and dosimetric characteristics of subjects in a Spanish population diagnosed with uveal melanoma treated with iodine 125 (I125) episcleral brachytherapy, who presented with post-treatment loss of useful visual acuity and global evolution of visual acuity. Methods: A single historic observational cohort study was undertaken. Patients with uveal melanoma were recruited between September 1995 and June 2015. Clinical, tumor and dosimetric data collection and visual acuity evaluations were performed under everyday practice conditions based on a useful visual acuity &gt;0.1 on the decimal scale. The baseline analysis was performed using descriptive and survival analyses according to Kaplan-Meier curves. Results: A total of 286 of the 665 patients diagnosed with uveal melanoma received episcleral brachytherapy, and 198 were included in the study. The mean follow-up time was 75.3 months (95% CI = 68.0-82.6). Patients with post-treatment useful visual acuity loss (n=94, 47%) presented the following characteristics: visual symptoms (n=80, p-value = 0.001); iris color (brown n=33, hazel green n=49, p-value = 0.047); Collaborative Ocular Melanoma Study size (medium n=80, p-value = 0.159); tumor, node, metastasis stage (T2: n=38, T3: n=38, p=0.012); shape (nodular n=67, mushroom-shaped n=26, p=0.001); posterior pole involvement (n=47, p=0.04); recurrence (n=10, p=0.001); and dose administered in the fovea, optic nerve and center of the eye (p&lt;0.002). Using Kaplan-Meier analysis, the mean overall survival of useful visual acuity was 90.19 months, and the probability of preserving useful visual acuity was 66% for one year, 45% for five years and 33% for ten years. Conclusion: Patients most likely to present with visual acuity loss were those with the following profile: elderly males with dark irises who were diagnosed with visual symptoms and exhibited a medium/large melanoma with a mushroom shape in the posterior pole (near the fovea and/or optic nerve). All patients treated with episcleral brachytherapy are likely to present with visual acuity loss, which is more pronounced in the first few years following treatment.

title: Vessel density in early-stage primary open angle glaucoma and pseudoexfoliation glaucoma: a comparative controlled optical coherence tomography angiography study

description: ABSTRACT Purpose: This study aimed to compare the vessel density of the optic nerve head and radial peripapillary capillary in the eyes with early-stage primary open angle glaucoma and pseudoexfoliation glaucoma and control eyes. Methods: With visual field mean deviation scores &gt;-6.0 dB, 54 eyes from 37 patients diagnosed with primary open angle glaucoma (n=18) and pseudoexfoliation glaucoma (n=18) and healthy controls (n=18) were enrolled in this cross-sectional observational study. Retrieved from optical coherence tomography angiography, vessel density for the optic nerve head and radial peripapillary capillary were analyzed according to the distribution of the data and appropriate tests. The diagnostic accuracy of vessel density parameters was also assessed. Results: The whole-image vessel density of the radial peripapillary capillary and inside-disc vessel density of the optic nerve head were significantly lower in eyes with primary open angle glaucoma and pseudoexfoliation glaucoma compared to those in the control eyes (p&lt;0.05). Compared to that in pseudoexfoliation glaucoma, the inside-disc vessel density of the optic nerve head was significantly lower in primary open angle glaucoma (p&lt;0.05). Inferotemporal sector vessel density of the optic nerve head for both primary open angle glaucoma and pseudoexfoliation glaucoma was significantly lower than that of the controls (p=0.009). In discrimination of primary open angle glaucoma vs. control and pseudoexfoliation glaucoma vs. control, area under the receiver operating characteristic curve values for inside-disc vessel density of the optic nerve head were 0.855 and 0.731, respectively (p&lt;0.001, p=0.018). However, in discrimination of primary open angle glaucoma vs. pseudoexfoliation glaucoma, area under the receiver operating characteristic curve values for whole-image and inside-disc vessel densities of the optic nerve head were 0.707 and 0.722 (p=0.034, p=0.023). Conclusions: Vessel densities of the optic nerve head and radial peripapillary capillary were significantly lower in eyes with primary open angle glaucoma and pseudoexfoliation glaucoma compared to healthy control eyes. In the early stage of glaucoma, the inside-disc vessel density of the optic nerve head slab may be lower in eyes with primary open angle glaucoma eyes compared to eyes with pseudoexfoliation glaucoma.

title: Comparison of the hypotensor effect between latanoprost versus selective laser trabeculoplasty obtained with the water drinking test

description: ABSTRACT Purpose: Glaucoma is the main cause of irreversible blindness worldwide. Peak intraocular pressure is one of the main risk factors for glaucoma progression, and intraocular pressure reduction remains the only therapeutic strategy for all types of glaucoma. The main purpose of our study was to compare the baseline and peak intraocular pressure reduction obtained with the water drinking test between the two eyes of the same patients using 0.005% latanoprost in one eye and selective laser trabeculoplasty application in the contralateral eye. Methods: This was a prospective, interventional, longitudinal, and randomized clinical trial, in which 30 consecutive glaucomatous patients, medically controlled using latanoprost monotherapy, were recruited from a single ophthalmological center. The patients’ eyes were randomized, and one eye was selected for SLT treatment and topical 0.005% latanoprost was introduced in the contralateral eye. The baseline intraocular pressure and peak intraocular pressure were evaluated 1 month (water drinking test 2) and 6 months (water drinking test 3) after treatment. Results: There was no significant difference between the mean pre-washout intraocular pressure in the randomized eyes for selective laser trabeculoplasty and latanoprost (13.6 ± 2.1 and 13.3 ± 1.8 mmHg, respectively; p=0.182). Regarding baseline intraocular pressure, there was no significant difference in the water drinking test 2 (p=0.689) and water drinking test 3 (p=0.06) between the groups. There was no significant difference in the intraocular pressure peak between the SLT and latanoprost groups at water drinking test 2 (p=0.771) or water drinking test 3 (p=0.774). Conclusions: The intraocular pressure reduction efficacy is similar between latanoprost and selective laser trabeculoplasty. Glaucomatous patients who are medically controlled with latanoprost and switch treatment to selective laser trabeculoplasty maintain control of intraocular pressure.

title: Effect of steroid eyedrops after trabeculectomy in glaucoma patients: a keratograph analysis

description: ABSTRACT Purpose: To investigate the use of preoperative steroid eyedrops in glaucoma patients undergoing trabeculectomy for ocular surface disease. Methods: A total of 31 eyes of 31 glaucoma patients were included. Only glaucoma patients who had been using at least three topical intraocular pressure-lowering medications for longer than 6 months were included. All patients were treated with loteprednol etabonate ophthalmic suspension 0.5% four times per day for 1 week before trabeculectomy. Data from baseline (day of surgery) and the follow-up visit (2 weeks after surgery) were included. All patients underwent a detailed ophthalmologic examination. Ocular surface disease was evaluated using the Ocular Surface Disease Index questionnaire and clinical measures, including tear breakup time, conjunctival hyperemia, and biomicroscopy to detect the presence or absence of keratitis. Ocular Surface Disease Index scores greater than 13 indicated a clinically relevant presence of ocular surface disease. In addition, all patients underwent keratograph analysis. The comparison of ocular surface disease before and after trabeculectomy was assessed using a paired test. Results: The mean age of the glaucoma patients was 69.90 ± 10.77 years. The average visual acuity was 0.40 ± 0.34 logMAR. The overall Ocular Surface Disease Index prevalence rate was 27.20 ± 17.56 units. Clinical assessment revealed no significant difference in bulbar redness, breakup time, or keratitis before and after surgery (p&gt;0.05 for all comparisons). Keratograph analysis showed that the only two parameters that were significantly different before and after trabeculectomy ewere the bulbar redness by keratograph (BR-K) and the average noninvasive tear breakup time. Patients presented more conjunctival hyperemia and shorter noninvasive tear breakup time after trabeculectomy as compared with before surgery (p=0.013 and p=0.041, respectively). Conclusions: The present study not only confirms the high prevalence of clinical findings of ocular surface disease in glaucoma patients but also reveals new objective parameters measured by keratograph analysis. Apart from using loteprednol etabonate ophthalmic suspension 0.5% 1 week before the surgery, our sample presented a worsening of conjunctival hyperemia (bulbar redness by keratograph) and also a shorter noninvasive tear breakup time postoperatively.
