title: Influence of upper blepharoplasty on intraocular lens calculation

description: ABSTRACT Purpose: To determine the effect of upper blepharoplasty on corneal topography and intraocular lens power calculation using Galilei and IOLMaster. Methods: Thirty patients submitted to upper blepharoplasty from May 2014 to March 2017 at the Hospital Oftalmológico de Sorocaba (São Paulo, Brazil) were included in this observational case series. All patients underwent imaging sessions with Galilei and IOLMaster preoperatively (baseline) and at 1 and 6 months postoperatively. Primary outcome measures using both devices included flattest, average, and steepest corneal curvature, corneal astigmatism, and blepharoplasty-induced corneal astigmatism. Determination of axial length and lens power calculation were performed using only IOLMaster (Holladay formula). Paired t-test and vectorial analysis were used for statistical analysis. Results: Sixty eyes from 30 patients were prospectively included. Vectorial analysis showed that 6 months after surgery, blepharoplasty induced on average 0.39 D and 0.31 D of corneal astigmatism, as measured with Galilei and IOLMaster, respectively. IOLMaster measurements showed that average corneal curvature (44.56 vs 44.64 D, p=0.01), steepest corneal curvature (45.17 vs 45.31, p=0.01) and corneal astigmatism (1.22 vs 1.34, p=0.03) were higher 6 months after surgery. IOLMaster measurements also showed that intraocular lens power was significantly smaller 6 months after surgery (22.07 vs 21.93, p=0.004). All other parameters showed no change for comparisons between baseline and 6 months (p&gt;0.05 for all comparisons). Conclusion: Upper eyelid blepharoplasty influenced intraocular lens calculation using the IOLMaster. However, the influence was not clinically significant. No topographic changes were found using Galilei.

title: Evaluation of retinal and choroidal microvascular changes in patients who received hydroxychloroquine by optical coherence tomography angiography

description: ABSTRACT Purpose: The aim of the study is to evaluate the retinal and choroidal microvascular changes via optical coherence tomography angiography in patients who received hydroxychloroquine. Methods: In total, 28 eyes of 28 patients (24 females, and 4 males) receiving treatment with hydroxychloroquine were assessed in this cross-sectional cohort study (hydroxychloroquine group). The high-and low-risk groups consisted of patients receiving hydroxychloroquine for ≥5 years (14 eyes of 28 patients) and &lt;5 years (14 eyes of 28 patients), respectively. A total of 28 age- and gender-matched volunteers were enrolled as the control group. The macular flow area (superficial, deep, and choriocapillaris), superficial and deep vessel density, foveal avascular zone area, central foveal thickness, and subfoveal choroidal thickness parameters were measured by optical coherence tomography angiography. Results: The mean age of the 28 patients who received hydroxychloroquine and the 28 age-matched controls was 45.5 ± 11.1 years (range: 29-70 years) and 44.5 ± 13.9 years (range: 28-70 years), respectively. In patients who received hydroxychloroquine, the values for the superficial, deep, and choriocapillaris macular flow areas were 13.578 ± 0.30, 13.196 ± 0.31, and 17.617 ± 0.42, respectively. In controls, these values were 16.407 ± 0.95, 13.857 ± 0.31, and 18.975 ± 0.76, respectively (p&lt;0.05 for all). The superficial, deep, and choriocapillaris flow areas were significantly smaller in patients who received hydroxychloroquine than those in controls (p&lt;0.05 for all). Superficial and deep vessel densities were significantly reduced in patients who received hydroxychloroquine in all regions (i.e., foveal, parafoveal, temporal, superior, nasal, and inferior) (p&lt;0.05 for all). Moreover, significant difference was observed between the groups in the foveal avascular zone area (superficial and deep), central foveal thickness, and subfoveal choroidal thickness (p&lt;0.05 for all). Conclusions: Retinochoroidal microvascular flow and vessel density of the macular area were significantly decreased in patients who received hydroxychloroquine. Hydroxychloroquine may damage the retinochoroidal microvascular architecture. Optical coherence tomography angiography may contribute to the early detection of hydroxychloroquine-induced retinal toxicity.

title: Prevalence of depressive and anxiety disorders in patients with glaucoma: a cross-sectional study

description: ABSTRACT Purpose: Our goal was to analyze the prevalence of depression and anxiety among patients with glaucoma and to identify risk factors related to these disorders. Methods: A cross-sectional study was carried out between August 2016 and August 2017 at the Hospital das Clínicas of Universidade Estadual de Campinas and at the Hospital Oftalmológico de Brasília to evaluate the prevalence of depressive and anxiety disorders among patients diagnosed with glaucoma. All patients underwent a complete ophthalmologic examination with standard automated perimetry to confirm the diagnosis of glaucoma. All participants were asked to complete the Hospital Anxiety and Depression Scale questionnaire. Results: One hundred and twenty-nine patients were included in the study. Seventy-four were men (57.36%) and 55 (42.64%) were women. The mean age of the patients was 70.14 ± 15.8 years. Ninety participants were white (69.77%) and 38 (29.46%) were black. The study demonstrated a prevalence of depression and/or anxiety at 10.08%. Logistic regression revealed that women were at higher risk for anxiety and/or depression (OR: 5.25, p=0.015) and patients with a larger number of comorbidities also were at higher risk for anxiety and/or depressive disorders (OR: 2.82, p=0.038). Conclusion: A significant proportion of patients with glaucoma present with depression and/or anxiety. Females and patients with comorbidities are at greater risk for these disorders.

title: Use of automated quantitative pupillometric evaluation for monitoring the severity of diabetic retinopathy

description: ABSTRACT Purpose: We aimed to evaluate the use of automated quantitative static and dynamic pupillometry in screening patients with type 2 diabetes mellitus and different stages of diabetic retinopathy. Method: 155 patients with type 2 diabetes mellitus (diabetes mellitus group) were included in this study and another 145 age- and sex-matched healthy individuals to serve as the control group. The diabetes mellitus group was divided into three subgroups: diabetes mellitus without diabetic retinopathy (No-diabetic retinopathy), nonproliferative diabetic retinopathy, and proliferative diabetic retinopathy. Static and dynamic pupillometry were performed using a rotating Scheimpflug camera with a topography-based system. Results: In terms of pupil diameter in both static and dynamic pupillometry (p&lt;0.05), statistically significant differences were observed between the diabetes mellitus and control groups and also between the subgroups No-diabetic retinopathy, nonproliferative diabetic retinopathy, and proliferative diabetic retinopathy subgroups. But it was noted that No-diabetic retinopathy and nonproliferative diabetic retinopathy groups have showed similarities in the findings derived from static pupillometry under mesopic and photopic conditions. The two groups also appeared similar at all points during the dynamic pupillometry (p&gt;0.05). However, it could be concluded that the proliferative diabetic retinopathy group was significantly different from the rest of the subgroups, No-diabetic retinopathy and nonproliferative diabetic retinopathy groups, in terms of all the static pupillometry measurements (p&lt;0.05). The average speed of dilation was also significantly different between the diabetes mellitus and control groups and among the diabetes mellitus subgroups (p&lt;0.001). While weak to moderate significant correlations were found between all pupil diameters in static and dynamic pupillometry with the duration of diabetes mellitus (p&lt;0.05 for all), the HbA1c values showed no statistically significant correlations with any of the investigated static and dynamic pupil diameters (p&gt;0.05 for all). Conclusion: This study revealed that the measurements derived from automated pupillometry are altered in patients with type 2 diabetes mellitus. The presence of nonproliferative diabetic retinopathy does not have a negative effect on pupillometry findings, but with proliferative diabetic retinopathy, significant alterations were observed. These results suggest that using automated quantitative pupillometry may be useful in verifying the severity of diabetic retinopathy.

title: Thermography in clinical ophthalmic oncology

description: ABSTRACT Purpose: The aim of this study was to present our own experience with the use of thermography as a complementary method for the initial diagnosis and differentiation of intraocular tumors, as well as for the evaluation of the efficacy of treatment of intraocular melanomas. Methods: The study group comprised 37 patients with intraocular tumors, including 9 with uveal melanoma, 8 with uveal melanoma after I125 brachytherapy, 12 with a focal metastasis to the uvea, and 8 with retinal capillary hemangioblastoma. A FLIR T640 camera was used to capture images in the central point of the cornea, eye area, and orbital cavity area. Results: Eyes with uveal melanoma had higher temperature compared with the fellow normal eye of the patient in the range of all measured parameters in the regions of interest. In the group of patients with melanoma after unsuccessful brachytherapy, higher temperature was observed at the central point of the cornea. In patients with tumor regression, all measured parameters were lower in the affected eye. We observed lower temperatures in the range of all tested parameters and areas in eyes with choroidal metastases. Eyes with diagnosed intraocular hemangioblastoma were characterized by higher parameters for the regions of interest versus eyes without this pathology. Conclusions: A thermographic examination of the eye can be used as an additional first-line diagnostic tool for the differentiation of intraocular tumors. Thermography can be a helpful tool in monitoring the treatment outcome in patients with intraocular melanoma.

title: Codeine plus acetaminophen improve sleep quality, daily activity level, and food intake in the early postoperative period after photorefractive keratectomy: a secondary analysis

description: ABSTRACT Purpose: To determine whether codeine plus acetaminophen after photorefractive keratectomy (PRK) have beneficial effects on sleep quality, activity levels, and food intake, beyond their effect of pain relief. Methods: We enrolled 40 patients (80 eyes) in this randomized, double-blind, paired-eye, placebo-controlled, add-on trial. Each eye was treated 2 weeks apart, and the patients were randomly allocated to receive either the placebo or the intervention (30 mg codeine and 500 mg acetaminophen) (4 times a day for 4 days). Outcomes were sleep quality, daily activity level, and food intake within 24-72 h post-photorefractive keratectomy, as measured by the McGill Pain Questionnaire. Results: Sleep quality and daily activity level were inversely associated with pain scores within the first 48 h post-photorefractive keratectomy. During the intervention, patients were significantly more likely to score their sleep quality as good at 24 h (relative risk=2.5; 95% confidence interval 1.48-4.21, p&lt;0.001) and 48 h compared to during placebo (relative risk=1.37; 95% confidence interval: 1.03-1.84, p=0.023). The probability of reporting good daily activity level at 24 and 72 hours post-photorefractive keratectomy was three times higher when patients received the intervention compared to the placebo (relative risk=3.0; 95% confidence interval: 1.49-6.15, p=0.006 and relative risk=1.31; 95% confidence interval: 1.02-1.67, p=0.021, respectively). No difference was observed in food intake. Conclusion: The oral combination of codeine and acetaminophen significantly improves sleep quality and daily activity level within the first 24-72 h post-photorefractive keratectomy compared to a placebo.

title: Acute corneal melting one week after an uncomplicated cataract surgery in a patient who previously underwent eyelid radiation and with undiagnosed rheumatoid arthritis: a case report

description: ABSTRACT This is a rare case report of acute, paracentral corneal melting and perforation occurring 1 week after an uneventful cataract surgery, with discussions on possible pathogenetic mechanisms. Relevant literature was also reviewed. Herein, a case of an 86-year-old woman with acute, paracentral, and sterile corneal melting and perforation in her left eye at 1 week after an uncomplicated cataract extraction is described. This occurs at the base of ocular surface disorders due to previous radiation of her lower eyelid and cheeks for the treatment of cancer and previously undiagnosed rheumatoid arthritis. She underwent surgical treatment using Gundersen’s conjunctival flap for the existing perforation due to low visual expectancies and reluctance to undergo corneal keratoplasty due to the risk of corneal graft rejection. The risk of coming across an acute corneal melting after an uncomplicated cataract surgery in the eyes with ocular surface disorders should always be considered.
