We suggest that conjunctival autografting is an effective technique in primary pterygium in terms of low recurrence rate. Increasing patient age is associated with significantly less risk of recurrence and complication.
Our aim was to compare the choroidal thickness in psoriasis patients and age- and gender-matched healthy volunteers. A total of 38 psoriasis cases and 38 age- and gender-matched controls were evaluated. The left eye was evaluated in all subjects. The choroidal thicknesses were measured at the subfovea and horizontally across the fovea at 500-μm intervals using enhanced depth imaging spectral domain optical coherence tomography. The points of measurement were 1500 µm temporal and nasal to the fovea. Choroidal thicknesses in psoriasis patients were thicker than those in the controls, but these differences were not statistically significant (P > 0.05). A positive correlation was present between the duration of disease and choroidal thickness at certain measurement points, but there was no significant correlation between the Psoriasis Area and Severity Index score and choroidal thickness. There was no significant difference between psoriasis patients and healthy controls in terms of choroidal thickness. However, choroidal thickness was associated with disease duration.
Purpose We aimed at measuring the choroid and retinal nerve fiber layer thickness with optic coherence tomography (OCT) in patients diagnosed with chronic obstructive pulmonary disease (COPD). Methods A total of 60 patients with COPD and 23 healthy controls were evaluated in the scope of this prospective, observational study. COPD patients were divided into two groups as those that were stable and those with an exacerbation based on the Global Initiative for Chronic Obstructive Lung Disease (GOLD) classification. Subfoveal choroid thickness (SFCT) of the patients and the control group was compared by measuring the choroid thickness at points 1000 µm nasal and temporal to the fovea and the mean retinal nerve fiber layer (RNFL) thickness. Results The subfoveal choroid thickness of the COPD patients in both the exacerbation and stable groups was found to be statistically significantly thinner than the control group (p=0.047 and p=0.046, resp.). No statistically significant difference was found between the subfoveal choroid thickness of the patients that were stable and those that had an exacerbation (p=0.813). No statistically significant difference was found between the mean RNFL, 1000 µm nasal, or 1000 µm temporal choroid thicknesses of the COPD patients and the control group (p=0.263, p=0.455, and p=0.611, resp.). Conclusion Decreased subfoveal choroid thickness was found in the COPD patients both during an exacerbation and in the stable period, when compared to the control group. The mean RNFL thickness was similar in the exacerbation and stable period of the stable COPD patients when compared to the control group. This suggests that ocular findings might be important in terms of COPD morbidity. This trial is registered with www.chictr.org.cn/enIndex.aspx.
To assess choroidal changes using enhanced depth imaging optical coherence tomography in coronavirus disease . Methods: Thirty-two patients with moderate COVID-19 and 34 healthy subjects were included in the study. Choroidal thickness was measured at 3 points as follows: at the subfovea, 1500 mm nasal to the fovea, and 1500 mm temporal to the fovea. The total choroidal area, luminal area, stromal area, and choroidal vascular index were measured with Image-J. All the measurements were performed during the disease and at 4 months after remission. Results: In the patient group, the subfoveal, nasal, and temporal choroidal thicknesses were decreased as compared with those in the controls, but without statistically significant differences (p=0.534, p=0.437, and p=0.077, respectively). The mean total choroidal, stromal, and luminal areas and choroidal vascular index were statistically significantly decreased in the patient group (p<0.001, p=0.001, p=0.001, and p=0.003; respectively). At 4 months after remission, the choroidal structural parameters and choroidal vascular index revealed statistically significant increases as compared with the baseline measurements in the patients with COVID-19 (all p<0.001 and p=0.047, respectively). Conclusion: The choroidal vascular and stromal parameters showed significant transient decreases during the disease course of COVID-19.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
