Comparison in conjunctival-Tenon's capsule thickness, anterior scleral thickness and ciliary muscle dimensions between Caucasians and Hispanic by optical coherence tomography.

PURPOSE: To investigate the differences in the dimensions of the anterior ocular segment, and specifically in conjunctival-Tenon's capsule thickness (CTT), anterior scleral thickness (AST) and ciliary muscle thickness (CMT), between Caucasian and Hispanic subjects using swept-source optical coherence tomography (SS-OCT). METHODS: Cross-sectional study including 53 Hispanic and 60 Caucasian healthy participants, matched by age, sex and refractive error, who underwent a complete ophthalmological examination. CTT, AST and CMT were manually measured in the temporal and nasal quadrants at 0, 1, 2 and 3 mm from the scleral spur using SS-OCT. RESULTS: Mean age and refractive error were 38.7 ± 12.3 years and -1.05 ± 2.6 diopters, and 41.8 ± 11.7 years and -0.50 ± 2.6 diopters for the Hispanic and Caucasians, respectively (p = 0.165 and p = 0.244). The CTT was increased in the temporal quadrant in the Hispanic group in the three studied regions (CTT1, CTT2 and CTT3; being the means 223.0 ± 68.4, 215.3 ± 66.4 and 203.8 ± 67.1 µm versus 190.8 ± 51.0, 189.4 ± 53.2 and 187.4 ± 55.3 µm respectively; p < 0.001). Larger AST values were observed in the temporal quadrant in the Hispanic group (AST2: 559.8 ± 80.8 µm and AST3: 591.6 ± 83.0 µm) compared to the Caucasian group (520.7 ± 50.1 and 558.9 ± 54.7 respectively; p ≤ 0.022). No differences were observed in the nasal quadrant for CTT, AST1 and AST3 (p ≥ 0.076). No differences emerged in the CM dimensions (p ≥ 0.055). CONCLUSION: CTT and AST measurements were thicker in the temporal quadrant of Hispanic patients compared to Caucasians. This could have implications for the pathogenesis of different ocular diseases.

TWO-YEAR CLINICAL OUTCOMES AFTER PHOTODYNAMIC ACUTE EXUDATIVE MACULOPATHY IN PATIENTS WITH CHRONIC CENTRAL SEROUS CHORIORETINOPATHY.

PURPOSE: To analyze the 2-year clinical outcomes after photodynamic therapy-induced acute exudative maculopathy (PAEM) in patients with chronic central serous chorioretinopathy. METHODS: Prospective observational study that included 64 eyes of 64 patients with chronic central serous chorioretinopathy who received half-fluence photodynamic therapy and had a 2-year follow-up. Patients were classified into two groups based on whether they had had PAEM at 3 days after treatment (PAEM+, n = 22; ≥50 µ m) increase in subretinal fluid or not (PAEM-, n = 42). Best-corrected visual acuity and subretinal fluid changes evaluated with optical coherence tomography were registered at 3 days, 1 month, 3 months, 1 year, and 2 years after photodynamic therapy. The number of recurrences, the appearance of outer retinal atrophy, and choroidal neovascularization were analyzed. RESULTS: Best-corrected visual acuity was 75.9 ± 13.6 (20/32) and 82.0 ± 11.0 letters (20/25) at 2 years in the PAEM+ and PAEM- groups, respectively ( P = 0.055). There were no differences in the best-corrected visual acuity change (4.2 ± 7.7 vs. 3.3 ± 7.1 letters; P = 0.654) and the subretinal fluid decrease (-117.3 ± 74.2 vs. -138.5 ± 83.6 µ m; P = 0.323) at 2 years between patients with and without PAEM. No differences in the number of recurrences ( P = 0.267), the appearance of choroidal neovascularization ( P = 0.155), or outer retinal atrophy ( P = 0.273) between both groups were noted. CONCLUSION: Patients with chronic central serous chorioretinopathy with and without PAEM presented similar results at 2 years in best-corrected visual acuity gain, subretinal fluid reduction, and complication rate.

Assessment of the anterior scleral thickness in central serous chorioretinopathy patients by optical coherence tomography.

PURPOSE: To assess the anterior scleral thickness (AST) and describe the presence of a visible supraciliary space (SCS) in central serous chorioretinopathy (CSC) patients by swept-source optical coherence tomography (SS-OCT). STUDY DESIGN: Cross-sectional comparative study. MATERIAL AND METHODS: Three groups were studied: 1) 64 eyes of 54 patients with CSC with persistent subretinal fluid (SRF); 2) 42 fellow eyes of CSC patients without SRF; 3) 65 eyes of 65 controls matched by age, sex and axial length (AL). The AST was measured in the temporal and nasal quadrants at 0, 1, and 2 mm from the scleral spur by SS-OCT. The presence of a visible SCS was also assessed. RESULTS: No differences were observed in the AST0 among the three groups (p≥ 0.665). The temporal AST1 was significantly thicker in the CSC group (530.3 ±67.1 µm) than in the controls (505.5 ±73.9; p=0.041). Mean AST2 was also thicker in the CSC group and the fellow eyes both for the temporal (519.4 ±89.1 µm and 519.8 ±98.5 µm respectively) and nasal quadrants (564.2 ±124.9 µm and 570.5 ±131.0 µm) than in the controls (450.1 ±76.8 and 473.3 ±111.6 µm) (all p≤0.001). A visible SCS was detected in the eyes of 8 CSC patients, in 4 fellow eyes and only in 1 control eye. CONCLUSIONS: AST measured by SS-OCT was significantly greater in CSC eyes than in healthy eyes. Also, a visible SCS was detected in CSC eyes. Thus, thicker sclera in CSC eyes could be associated with the physiopathology of this disease.

[Impact of hospital admission on centenarians admitted due to an acute illness. A description of a series of 165 cases and comparison with the literature]. / Impacto de la hospitalización en pacientes centenarios ingresados por enfermedad aguda. Descripción de una serie de 165 casos y comparación con la literatura.

INTRODUCTION: The number of centenarians is increasing with the aging of the Spanish population. This age group might present different clinical features from younger groups. This study was carried out to determine the impact hospital admission on centenarians with an acute disease. MATERIALS AND METHODS: A retrospective observational study was conducted that included patients ≥100 years-old admitted from 1995 to 2016 to a third level university hospital and attended by the Geriatrics department in the acute ward, the Orthogeriatric ward, and by request. An analysis was made using the clinical-administrative databases containing information about the demographics, clinical, functional and cognitive features, length of hospital length, as well as discharge destination. RESULTS: The study included 165 patients with a mean age of 101.6 ± 1.7 (range 100-109) years, of whom 140 (85%) were female. The mean hospital stay was 10.3 ± 7.4 days. Respiratory infections (41%) were the most common cause of admission to the Acute Geriatric Unit (AGU). The overall in-hospital mortality was 16%, but mortality in AGU reached up to 31%. There was an increase on moderate-severe functional disability (51% to 96%), and on the inability to walk independently (52% to 99%) from baseline to admission. There was a reduction in people living in their own home from 71% prior to admission to 29% at hospital discharge. CONCLUSIONS: Centenarians who required hospital admission showed a high rate of mortality, a significant deterioration in their functional capacity, and a decrease in their chances of going back to their own home at discharge.
