[PMID: 37640205 DOI: 10.1016/j.pdpdt.2023.103773] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/25/2023] [Revised: 08/18/2023] [Accepted: 08/25/2023] [Indexed: 08/31/2023]
Abstract
BACKGROUND To compare ocular findings of acromegaly patients with healthy individuals and investigate the relation of serum levels of insulin-like growth factor (IGF-1) along with growth hormone (GH) and pituitary tumor (adenoma) dimensions (TD) with specific ocular parameters. METHODS The ocular parameters of acromegaly patients (n = 38) were compared with those of healthy subjects (n = 36). These parameters were intraocular pressure, keratometric (K1-K2) values, central corneal thickness (CCT), total axial length along with anterior chamber-lens-vitreous length, retinal nerve fiber layer (RNFL) thickness, central foveal thickness (CFT), choroidal thickness (CT), ganglion cell layer thickness (GCLT), and inner plexiform layer thickness (IPLT). Also investigated was whether there was a correlation between disease duration, TD, GH, IGF-I, CCT, RNFL, CFT, GCLT, IPLT, and CT. RESULTS The lens length of the acromegaly group was increased (p = 0.014). GH and IGF-1 levels were positively correlated with CT and CCT, respectively (p = 0.041, r = 0.343) (p = 0.03, r = 0.347). Analysis of TD also found a highly negative correlation with the mean RNFL thickness of the acromegaly patients (p < 0.01, r = -0.603). The mean value of the inner parts of GCLT and IPLT was negatively correlated with TD (p = 0.041, r = -0.343 and p = 0.025, r = -0.379, respectively). CONCLUSION Serum IGF-1 and GH levels might be determinant factors in CCT and CT, respectively. The pituitary adenoma size increasing may be prone to lead RNFL, ganglion cell layer, inner plexiform layer thinning. Increased lens thickness was found in the acromegaly group.

Alteration in choroidal microvasculature determined by optical coherence tomography angiography in patients with acromegaly. Photodiagnosis Photodyn Ther 2021; 36:102590. [PMID: 34673271 DOI: 10.1016/j.pdpdt.2021.102590] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/17/2021] [Revised: 10/05/2021] [Accepted: 10/15/2021] [Indexed: 11/21/2022]
Abstract
AIM We aimed to investigate the retinal layers and macular capillary structure using optical coherence tomography angiography (OCTA) with acromegaly patients and determine the relationship between OCTA parameters and disease duration, Growth hormone (GH) and Insuline growth factor (IGF - 1) levels. PATIENTS AND METHOD Twenty-two patients with acromegaly who were followed up in the endocrinology outpatient clinic of Sisli Hamidiye Etfal Health Training and Research Hospital, were recruited into the study. Healthy control group was consisted of 22 age and gender matched subjects. Complete opthalmological examination including best visual acuity (BCVA), axial lenght, intraocular pressure (IOP) measurement, anterior segment and fundus examination, central corneal thickness with pachymetry and OCTA measurement were performed in the patients and healthy control group. Foveal avascular zone (FAZ), foveal vascular density (FVD), parafoveal vascular density (PFVD), choroidal flow (CF), foveal thickness (FT) and choroidal thickness (CT) were compared beetwen groups. Correlation between disease duration, GH and IGF-1 levels and OCTA parameters were evaluated. RESULTS There was no statistically significant difference between the groups in terms of BCVA, axial length, IOP, FT, FAZ, FD and PFVD. Choroidal thickness and CF was significantly high in the patients group compared to healthy controls (respectively, p = 0.003, p = 0.022). The mean follow-up period in patients with acromegaly was 90±50.2 months. There was a significant correlation between GH and subfoveal choroidal thickness in the patient group (p < 0.001, r = 0.52), a significant correlation was determined between disease duration and corneal thickness (p = 0.01, r = 0.41). In addition, an inverse correlation was detected between the IGF-1 level and the FAZ domain (p = 0.022, r= -0.34). CONCLUSION In patients with acromegaly, choroidal vasculature seems to be more affected than the retinal vasculature.

Abstract
PURPOSE Evaluation of the lacrimal gland volume (LGV) and its correlation with tear film functions, serum growth hormone (GH) and insulin-like growth factor-1 (IGF-1) levels in acromegaly patients compared to a control group was aimed. METHODS This prospective case-control study included the eyes of 38 patients with uncontrolled (UA) and 48 patients with controlled acromegaly (CA) and 44 patients with nonfunctioning pituitary adenoma. LGV of the patients was evaluated at the baseline, 3rd, and 6th-month visits with magnetic resonance imaging. Schirmer's test, tear breakup time (TBUT), and ocular surface disease index (OSDI) scores were evaluated at the same visits. Their correlation with serum IGF-1 and GH was investigated. Main outcome measure was the difference in mean LGV. RESULTS The mean LGV of the acromegaly patients at the baseline visit (116.0 ± 33.2 mm3) and the 3rd-month visit (119.5 ± 36.4 mm3) was higher than the control group (65.2 ± 22.3 mm3 and 63.2 ± 22.3 mm3, respectively; p < 0.001) without any significant difference between the UA and CA patients in the LGV in three consecutive visits (p > 0.05). Among all patients, IGF-1 and GH levels showed a positive correlation with the LGV (p < 0.001; r = 0.52; r = 0.6, respectively). However, Schirmer, TBUT, and OSDI scores did not show any difference among the three groups at each visit (p > 0.05). CONCLUSION Acromegaly patients may have larger lacrimal glands compared to the controls and this increase correlated with the increased IGF-1 and GH levels. Lacrimal gland volume may have no effect on its tear film related functions.

Abstract
PURPOSE This study aimed to evaluate the retinal blood vessel parameters and the foveal avascular zone (FAZ) area using optical coherence tomography angiography (OCTA) in patients with acromegaly in comparison with healthy controls. METHODS A total of 45 patients with acromegaly and 45 healthy controls were included in this study. In all patients, the vessel density (VD) of the deep and superficial macular vascular networks and the foveal avascular zone (FAZ) were measured using OCTA. The correlation of insulin-like growth factor 1 (IGF-1) level and disease duration with deep macular VD and FAZ values was analyzed. All parameters were registered. Results were assessed and compared between the two groups. RESULTS Deep macular plexus VD values were lower in patients with acromegaly compared to the control group. No significant differences in VD values in the superficial segment, except for that in the inferior parafovea (P = .01) were found between the two groups. Furthermore, patients with acromegaly showed enlargement in the superficial (P = .30) and deep FAZ areas (P < .001). IGF-1 level and disease duration showed a significant negative correlation with the deep whole image (R = -0.216, P = .041, R = -0.339, P = .001, respectively), deep parafovea (R = -0.271, P = .01; R = -0.372, P < .001, respectively), deep parafovea superior hemi (R = -0.342, P = .001; R = -0.350, P = .001, respectively), deep parafovea temporal (R = -0.224, P = .034; R = -0.234, P = .026, respectively), deep parafovea nasal (R = -0.320, P = .002; R = -0.361, P < .001, respectively), and deep parafovea superior VD values (R = -0.293, P = .005; R = -0.307, P = .003, respectively) and a significant positive correlation with the deep FAZ area values (R = 0.244, P = .02; R = 0.329, P = .002, respectively). CONCLUSION VD values in the deep macular capillary plexus were lower in patients with acromegaly, and the superficial and deep FAZ area enlarged. Patients with acromegaly may have an increased risk of developing ocular vascular complications. OCTA can be used to evaluate retinal blood VD in patients with acromegaly.

Abstract
PURPOSE Although optical coherence tomography (OCT) of the eyes has been studied to detect and monitor sellar masses, there is no recommendation for selecting the most effective measurement of OCT in clinical practice. Thus, we conducted a meta-analysis to examine the efficacy of OCT in sellar mass lesions. METHODS We conducted a literature search in PubMed and EMBASE through April 26, 2020. The primary outcomes were the thickness of the peripapillary retinal nerve fiber layer (pRNFL) and the macular ganglion cell complex (mGCC). The secondary outcomes included the thickness of the macular ganglion cell and inner plexiform layer (mGCIPL) and macular thickness. Random-effects models were used in all meta-analyses. Additionally, we conducted meta-regressions and subgroup analyses. RESULTS We included 22 studies, involving 1347 eyes of patients and 1198 eyes of controls. When compared with the control group, the reductions in pRNFL, mGCC and macular thickness in the patient group were significantly different, whereas significant thinning of the mGCIPL was restricted to the nasal hemiretina. Furthermore, we found that before visual field (VF) defects occurred, significant thinning of the pRNFL and mGCC thickness could be detected by OCT. The change in OCT parameters also showed different patterns in different types of pituitary adenomas. CONCLUSIONS Sellar mass lesions were associated with the changes in OCT measurements. The characteristic patterns of the OCT parameters may refine the diagnostic accuracy. Moreover, the alterations of OCT metrics before VF defects indicate the efficacy of OCT in early detection. Different types of pituitary adenomas may vary in OCT measurements, and their specific features warrant further research efforts.

Abstract
BACKGROUND The aim of study was to evaluate the retinal layers and macular capillary network with OCTA in acromegaly patients, to compare with healthy population. METHODS In this prospective, observational, and comparative study, 40 acromegaly patients and 40 healthy control participants were included. Serum IGF-1 levels and disease duration of all patients were noted. Macular layers and angiography scanning was performed with a Zeiss Cirrus 5000 OCTA system. Macular thickness, RNFL, and GC-IPL values were obtained. For central vessel and perfusion density, central 6 mm was obtained and was evaluated by dividing into three groups (inner, outer, full). FAZ parameters were evaluated dividing into three groups (area, perimeter, circularity index). Analysis of the data was performed with the SPSS for Windows. RESULTS There was no significant difference between the patient group and the control group in terms of age, gender, best corrected visual acuity (BCVA), spherical equivalent (SE), intraocular pressure (IOP), and axial length (AL). The mean follow-up period after diagnosis was 11.0 ± 5.5 years. Central and mean macular thicknesses were also significantly higher in the acromegaly group (p < 0.05). Superior, inferior, and average RNFL thicknesses were also significantly thinner in the acromegaly group (p < 0.05). When OCTA parameters were compared between groups, there was a significant decrease in central vessel density (CVD) and central perfusion density (CPD) values in all regions in acromegaly group compared with controls (p < 0.05). CONCLUSION Our findings with OCTA show that acromegaly causes a significant capillary network decrease according to the healthy subjects.

Abstract
OBJECTIVE To evaluate the short-term changes in subfoveal choroidal thickness (SFCT), ganglion cell complex (GCC) analysis, and retinal nerve fiber length (RNFL) of patients with chronic obstructive pulmonary disease (COPD) in a 3-month follow-up. MATERIALS AND METHODS Forty-eight patients with COPD (96 eyes) and 40 control subjects (80 eyes) were enrolled in our study. COPD patients were grouped according to disease severity as Group 1 (mild-moderate) and Group 2 (advanced). GCC, RNFL, and SFCT analysis by Cirrus SD-OCT were obtained for all eyes, in two consecutive examinations with a 3-month interval. RESULTS SFCT in Group 2 was lower than Group 1 and control group in the initial and 3rd month examination (p < 0.001, respectively). Inferior RNFL in Group 2 were lower than control group in the initial and 3rd month examination (p = 0.002, p < 0.001, respectively) Temporal RNFL were lower in Group 2 than Group 1 in 3rd month examination (p = 0.009). Average, superior, superotemporal, inferior, and inferonasal GCC analyses of the Group 2 were lower than control group both in the initial and 3rd month examination (p = 0.001, p < 0.001, respectively) SFCT, average, and superior GCC of Group 2 were significantly reduced during the 3-month follow-up (p < 0.001). CONCLUSION Hypoxia is thought to be the underlying mechanism in COPD, which may influence retinal and choroidal OCT parameters. Decrease in blood flow of optic nerve head, increased vascular resistance, and reduced blood flow in choroid may affect the visual ability in these patients, which should be kept in mind during their follow-up.

Abstract
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.

The Predictive Value of Suprasellar Extension for Visual Function Evaluation in Chinese Patients with Nonfunctioning Pituitary Adenoma with Optic Chiasm Compression. World Neurosurg 2018; 116:e960-e967. [PMID: 29857216 DOI: 10.1016/j.wneu.2018.05.141] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/11/2018] [Revised: 05/18/2018] [Accepted: 05/19/2018] [Indexed: 11/16/2022]
Abstract
OBJECTIVE To analyze the quantitative relationship between suprasellar extension (SSE) and visual function impairment in Chinese patients with nonfunctioning pituitary adenoma (NFPA) with optic chiasm compression. METHODS We retrospectively reviewed 117 patients with NFPA and optic chiasm compression treated at our hospital between January 2013 and December 2016. The quantitative relationships between SSE detected on sagittal and coronal magnetic resonance imaging (MRI) sections and visual function, including visual acuity (VA) and visual fields (VFs), were analyzed. The cutoff value of SSE to predict a VF defect (VFD) was calculated using a receiver operating characteristic curve. The mean deviation (MD) value was used to quantitatively analyze the VFs, and multiple linear regression analysis was performed to investigate risk factors of VFD. RESULTS Among 117 patients with NFPA, 77 (65.8%) had VFD, and the mean VA was 0.42 ± 0.38 logMAR. The cutoff value of the sagittal SSE was 14.0 mm, with 77.9% sensitivity and 80.0% specificity, and the cutoff value of the coronal SSE was 15.8 mm, with 81.8% sensitivity and 85.0% specificity. The values of SSE on 2 MRI sections were correlated with VA (P < 0.001) and the MD (P < 0.001). Multiple linear regression analysis demonstrated that SSE on sagittal views (P < 0.001), SSE on coronal views (P < 0.001), duration of the disease (P = 0.027), and apoplexy (P = 0.036) were related to the degree of VF damage. CONCLUSIONS VFD in patients with NFPA with chiasm compression can be predicted by SSE on MRI. There is a linear correlation between SSE and the MD value.

Abstract
PURPOSE 1) To compare the retinal, choroidal, Haller's layer, and Sattler's/choriocapillaris thicknesses of untreated acromegaly patients without chiasm compression or diabetes mellitus and healthy controls. 2) To evaluate the correlations of retinal and choroidal thicknesses with serum growth hormone (GH) and insulin-like growth factor 1 (IGF) burden. METHODS This prospective, case-control study included 27 untreated acromegaly patients and 27 sex-matched and age-matched controls. Subfoveal choroidal, Haller's layer and Sattler's/choriocapillaris thicknesses were determined by enhanced-depth imaging optical coherence tomography (EDI-OCT). Foveal and macular retinal thicknesses were determined with SD-OCT. GH and IGF-1 burdens were defined as the product of disease duration and treatment-naïve serum GH and IGF-1 levels. RESULTS Compared with healthy controls, patients with acromegaly exhibited significantly increased foveal retinal (p = 0.003), subfoveal choroidal (p < 0.001), and Haller's layer (p < 0.001) thicknesses, with no differences in Sattler's/choriocapillaris layer thickness. Multiple point measurements in the posterior pole area showed equally increased nasal and temporal parts of the choroid. The retinal thickness maps of the two groups did not significantly differ. Correlation analysis indicated that choroidal thickness was significantly correlated with disease duration (p = 0.01), serum IGF-1 level (p = 0.03) and IGF-1 burden (p = 0.009). No significant correlations were detected between choroidal thickness and GH burden (p = 0.44). Retinal thickness was not significantly correlated with any factor. CONCLUSION The choroidal thickness of acromegaly patients was greater than that of healthy controls and was significantly correlated with disease duration, IGF-1 level and IGF-1 burden, indicating that excessive serum IGF-1 and its exposure time have a combined effect on choroidal thickness.

Abstract
Purpose The present study focused on the assessment of the mRNA levels of the insulin-like growth factor (IGF) family in patients with the exudative form of age-related macular degeneration (AMD) before and after ranibizumab intravitreal injections. Patients and methods An analysis of the expression profile of the IGF family of genes in patients with AMD was carried out using the oligonucleotide microarray and quantitative reverse transcriptase polymerase chain reaction (RT-qPCR) methods. Results In the peripheral blood mononuclear cells (PBMCs) obtained from AMD group receiving ranibizumab compared to the peripheral blood mononuclear cells from AMD group before ranibizumab treatment using oligonucleotide microarray technique, six statistically significant differentially expressed transcripts related to the IGF family were detected (unpaired t-test, p<0.05, fold change >1.5). Moreover, analysis using the real-time RT-qPCR technique revealed statistically significant differences in the IGF2 and IGF2R mRNA levels (Mann–Whitney U test, p<0.05) between the two groups that were studied. Statistical analyses of both oligonucleotide microarray and real-time RT-qPCR results demonstrated a significant decreased expression only for IGF2 mRNA. Conclusion Our results revealed a changed expression of IGF2 mRNA after ranibizumab treatment.

Abstract
Increased secretion of growth hormone and insulin-like growth factor-1 in acromegaly has various effects on multiple organs. However, the ocular effects of acromegaly have yet to be investigated in detail. The aim of the present study was to compare retina ganglion cell/inner plexiform layer (GCIPL) and peripapillary nerve fiber layer thickness (pRNFL) between patients with acromegaly and healthy control subjects using spectral domain optical coherence tomography (SD-OCT). This cross-sectional, comparative study included 18 patients with acromegaly and 20 control subjects. All participants underwent SD-OCT to measure pRNFL (in the seven peripapillary areas), GCIPL (in the nine ETDRS areas), and central macular thickness (CMT). Visual field (VF) examinations were performed using a Humphrey field analyzer in acromegalic patients. Measurements were compared between patients with acromegaly and control subjects. A total of 33 eyes of 18 patients with acromegaly and 40 eyes of 20 control subjects met the inclusion criteria of the present study. The overall calculated average pRNFL thickness was significantly lower in patients with acromegaly than in control subjects (P = 0.01), with pRNFL thickness significantly lower in the temporal superior and temporal inferior quadrants. Contrary to our expectations, pRNFL thickness in the nasal quadrant was similar between acromegalic and control subjects. The mean overall pRNFL thickness and superonasal, nasal, inferonasal, and inferotemporal quadrant pRNFL thicknesses were found to correlate with the mean deviation (MD) according to Spearman's correlation. However, other quadrants were not correlated with VF sensitivity. No significant difference in CMT values was observed (P = 0.6). GCIPL thickness was significantly lower in all quadrants of the inner and outer macula, except for central and inferior outer quadrants, in the acromegaly group than that in the control group (P < 0.05). GCIPL thicknesses of the inferior inner and outer macula quadrants were found to correlate with MD, whereas no correlation was observed between other quadrants and VF sensitivity. We demonstrated that GCIPL thickness decreased in patients with acromegaly compared with that in control subjects. However, the nasal quadrant pRNFL thickness was similar in acromegaly, in contrast to our expectations. SD-OCT may have utility in the assessment of the effects of acromegaly on retinal structures.

Abstract
INTRODUCTION Chronic obstructive pulmonary disease (COPD) has multisystemic implications and comorbidities. Hypoxia and systemic inflammation are thought to involve oculary structures. In this study, our aim is to evaluate retinal nerve fiber and choroidal thickness and retinal vessel diameter using the spectral-domain optical coherence tomography (SD-OCT) in COPD subjects. METHODS Forty-three subjects diagnosed with COPD according to the Global Initiative for Chronic Obstructive Lung Disease criteria at the Pulmonology Department of Pamukkale University were enrolled in the study. All subjects underwent respiratory function testing and a carbon monoxide diffusion test. To determine hypoxic state, arterial blood gas analysis was performed. The control group consisted of 31 subjects with comparable age and gender distribution. All participants underwent a standard ophthalmic examination including visual acuity assessment, biomicroscopy, air-puff tonometry, indirect retinoscopy, and SD-OCT measurements. RESULTS The mean subfoveal choroidal thickness (SFCT), foveal thickness, and retinal arteriolar caliber were found to be similar in both groups, while the mean retinal venular caliber value was markedly higher in the COPD group. The mean peripapillary retinal nerve fiber layer (RNFL) thickness was 100.2±11.8 µm in the COPD group and 105.6 ± 8.1 µm in the control group (P = .03). The inferior quadrant RNFL was significantly thinner in the COPD group. CONCLUSIONS The results of this study showed increasing diameter of the retinal veins, thinning of the RNFL, and SFCT may be associated to chronic inflammation and hypoxia in subjects with COPD. Future guidelines may include ocular findings to the present systemic manifestations of COPD.
