Genç ÇD, Yılmaz AK, Kurt MM, Özgür G, Aydın E, Yılmaz C. Comparison of choroidal thickness, superficial and deep retinal vascular indices, and foveal avascular zones: Martial arts athletes vs healthy non-athletes. Photodiagnosis Photodyn Ther 2024; 48:104266. [PMID: 38977118 DOI: 10.1016/j.pdpdt.2024.104266] [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: 05/07/2024] [Revised: 06/28/2024] [Accepted: 07/01/2024] [Indexed: 07/10/2024]
Abstract
AIM The study aims to compare choroidal thickness, deep and superficial retinal capillary plexuses, and foveal avascular zone (FAZ) parameters in elite martial arts athletes and a healthy sedentary control group. METHODS The study included martial arts athletes (32 individuals, 64 eyes) and healthy sedentary persons (43 individuals with healthy sedentary lifestyles, 86 eyes) aged 18-35 years. In this single non-repeated observational and cross-sectional study, choroidal thickness, superficial and deep retinal capillary plexuses, and FAZ measurements were measured using Swept-source optical coherence tomography angiography (SS-OCTA) and compared between groups. RESULTS No statistically significant differences were found (p > 0.05) in age, IOP, AL (axial length), and best-corrected visual acuity (BCVA) parameters between groups. There were no statistically significant differences between the groups in choroidal thickness, superficial and deep retinal capillary plexuses, and FAZ parameters determined by the OCTA method (p > 0.05). CONCLUSION In our study, we observed that the retinal and choroidal structures of martial art athletes and healthy sedentary individuals were similar. This observation implies that the putative microvascular effects on the choroid and retina in martial arts, especially those based on the anaerobic energy system, may reflect similar outcomes to those observed in individuals with sedentary lifestyles characterized by healthiness.

Abstract
BACKGROUND To evaluate the effect of sodium-glucose cotransporter-2 inhibitor treatment on choroidal vascular parameters in patients with type 2 diabetes mellitus (T2DM). METHODS Twenty eyes of 20 patients with T2DM without diabetic retinopathy and 20 eyes of 20 age- and sex-matched patients as the control group were included in the study. The patients were evaluated using enhanced depth imaging optic coherence tomography before treatment and at the third month of treatment. The choroidal images were binarized into luminal areas (LAs) and stromal areas (SAs). The choroidal vascularity index (CVI) was defined as the ratio of the LA to the total circumscribed choroid area (TCA). RESULTS The mean age of the patients was 56.65±8.41 years. The patients' mean disease duration was 6.65±5.72 years, the mean HbA1c level was 8.89±1.62%, and the mean body mass index was 33.13±4.84 kg/m2. The subfoveal TCA, subfoveal LA, subfoveal SA, total TCA, total LA, and total SA values of the patient group were found to be significantly lower than those of the control group (p = 0.006, p = 0.003, p = 0.028, p = 0.001, p = 0.001, and p = 0.006, respectively). There was a significant increase in the subfoveal TCA, subfoveal LA, subfoveal SA, subfoveal CVI, total TCA, total LA, and total SA values after empagliflozin treatment compared to before empagliflozin treatment (p = 0.005, p = 0.003, p = 0.021, p = 0.032, p < 0.001, p < 0.001, and p = 0.001 respectively). CONCLUSIONS Empagliflozin provides an improvement in diabetic choroidal changes through its effect on choroidal vascularity parameters.

Abstract
BACKGROUND To evaluate optic disc and retinal vascular densities in obese patients using optical coherence tomography angiography (OCTA). METHODS This study included 27 eyes from 27 obese patients with a body mass index (BMI) of ≥35 who were scheduled for bariatric surgery at the general surgery clinic and 26 eyes from 26 healthy individuals with a BMI of 18.5-24.9 kg/m2 who were of similar age and gender to the obese group. The macular vascular densities of the superficial and deep capillary plexuses (SCP and DCP, respectively), choriocapillaris flow area, optic disc peripapillary vascular density, and retinal thicknesses were evaluated using the OCTA device in obese patients and controls. RESULTS The mean age of the obese patients was 35.89 ± 10.93 years, and that of the controls was 32.31 ± 7.88 years (p = 0.199). The mean BMI values of the obese and control groups were 45.04 ± 6.89 kg/m2 and 23.19 ± 1.66 kg/m2, respectively (p < 0.0001). The whole, parafoveal, and perifoveal vascular density values of the SCP and those of the DCP were statistically significantly lower in the obese group than in the control group (p = 0.004, p = 0.011, p = 0.006, p = 0.036, p = 0.029, and p = 0.024, respectively). There was no significant difference between the two groups in terms of optic disc vascular density. Full retinal perifoveal thickness, full retinal perifoveal volume, inner retinal perifoveal thickness, and inner retinal perifoveal volume were statistically significantly lower in obese patients compared to the controls (p = 0.043, p = 0.042, p = 0.027, and p = 0.024, respectively). In addition, statistically significant negative correlations were found between BMI and the whole, parafoveal, and perifoveal vascular densities of the SCP and DCP and the whole vascular density values of the optic disc for all vessels and small vessels (p = 0.017, r = -0.327; p = 0.043, r = -0.280; p = 0.033, r = -0.293; p = 0.034, r = -0.291; p = 0.017, r = -0.327; p = 0.023, r = -0.311; p = 0.031, r = -0.296; and p = 0.047, r = -0.274, respectively). CONCLUSION We consider that the decrease in retinal vascular density and retinal thickness in obese patients is responsible for obesity-induced oxidative stress, increased inflammatory cytokines, and microvascular damage.

[PMID: 37103665 DOI: 10.1007/s11695-023-06607-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/19/2022] [Revised: 04/13/2023] [Accepted: 04/17/2023] [Indexed: 04/28/2023]
Abstract
Our review aimed to assess the effects of bariatric surgery-induced weight loss on ocular functions. We focused on retinochoroidal microcirculation, glaucomatous factors, and the condition of the eye surface pre- and postoperatively. The review covered 23 articles, including five case reports. Bariatric surgery positively impacts retinochoroidal microcirculation. The arterial perfusion and vascular density improve, venules constrict, and the arteriole-to-venule ratio increases. Weight loss positively correlates with intraocular pressure decrease. The impact of postoperative weight loss on the choroidal thickness (CT) and the retinal nerve fiber layer (RNFL) is still unclear. The correlation between ocular symptoms and hypovitaminosis A needs to be evaluated. Further research is required, especially regarding CT and RNFL, mainly focusing on long-term follow-up.

Abstract
Aim: The aim of this prospective, controlled, non-randomized study was the comparison of the retinal microvascular parameters of obese and nonobese adults. Methods: 184 eyes of 92 subjects were separated to 3 groups. 68 eyes were in the normal weight group, with a body mass index between 18.5 and 24.5 kg/ m2, 60 eyes were in the overweight group, with a body mass index between 25-29.9 kg/ m2, and 56 eyes were in the obese group, with a body mass index ≥ 30 kg/ m2. All the volunteers were applied visual acuity, ocular motility testing, and slit lamp and mydriatic fundus examination. Optical Coherence Tomography Angiography (OCT-A) scanning was practiced with Optovue (Optovue, Inc; Fremont, CA) on a 6.00 x 6.00 mm macular region, in the central fovea. Results: 184 eyes of ninety-two patients were involved in this prospective study. The vessels' density (VD) in the optic nerve head (ONH) were significantly lower in the overweight and obese adult volunteers compared to the normal weight control group. However, other OCTA parameters (including macular VDs, Foveal avascular zone (FAZ), choriocapillaris plexus (CCP) area) did not demonstrate any significant difference between groups. Subfoveal choroidal thickness (SCT) was higher in the overweight and obese patients when compared to the normal weight control group. Central macular thickness (CMT) did not reveal any significant difference between groups. Conclusion: Even though clinicians are limited in pointing out any differential findings in obese patients only by fundus examination, OCT-A provides a predictable view of the microvascular changes in the retina and choroid in obese patients.

Abstract
AIM The present study explores the effects of Body Mass Index (BMI) on choroidal thickness, the deep and superficial retinal capillary plexuses, and the foveal avascular zone (FAZ). METHODS The subjects in this prospective study were divided into five groups based on their calculated BMI. Choroidal thickness, superficial and deep retinal capillary plexuses, and FAZ were measured using enhance depth imaging (EDI) and optical coherence tomography angiography (OCTA). The groups were then compared and correlations with BMI were evaluated. RESULTS The study included 210 eyes of 105 subjects. The comparison of the BMI groups revealed a significant decrease in the mean choroidal thicknesses in the obese groups (p = 0.001), and a significant negative correlation between BMI and mean choroidal thickness (p = 0.02). The results of the analysis of the mean superficial and deep retinal capillary plexuses did not differ between the groups (p = 0.089, p = 0.808 respectively), while the deep FAZ measurements revealed a significant decrease in the obese groups (p = 0.003). CONCLUSION Choroidal thickness and deep FAZ are significantly negatively correlated with BMI, suggesting potential choroidal and retinal microvascular effects of obesity.

Abstract
PURPOSE To investigate the association of body mass index (BMI) and waist-to-hip ratio (WHR) with macular vessel density (VD) and foveal avascular zone (FAZ), using optical coherence tomography angiography (OCTA), in healthy Chinese adults. DESIGN Cross-sectional study. METHODS A total of 1555 Chinese adults aged ≥ 50 years with no history of ocular disease were recruited from communities in Guangzhou, China. The OCTA was performed with a 6 × 6 mm macular angiography model. The FAZ of the superficial capillary plexus (SCP), and VD of SCP and deep capillary plexus (DCP) were calculated. Univariable and multivariable linear regression analyses were used to evaluate the effect of BMI and WHR on VD and FAZ. RESULTS The VD of the SCP increased as BMI increased, with average measurements of 39.30 ± 2.14 for normal, 39.52 ± 2.07 for overweight, and 39.76 ± 2.03 for obesity (P = .001). The VD of the DCP also increased with increasing BMI (P = .009). Multiple regression models confirmed a positive association between generalized obesity and superficial VD in the whole image (β = 0.350, P = .008), inner circle (β = 0.431, P = .032), and outer circle (β = 0.368, P = .005). After adjusting for confounders, tertile 3 of the WHR level was positively associated with superficial VD (β = 0.472, P = .033) and deep VD (β = 0.422, P = .034) only in the inner circle. CONCLUSIONS Generalized obesity was associated with increased superficial VD, while abdominal obesity was associated with increased superficial and deep VD only in the inner circle. Different manifestations of the retinal microvasculature may reflect distinct roles of body composition on macular vessel alterations and disease occurrence.

Abstract
Childhood obesity has reached epidemic levels worldwide. Overweight and obesity is associated with an increase in several inflammatory markers, leading to chronic low-grade inflammation responsible for macro- and microvascular dysfunction. While the impact of obesity on overall health is well-described, less is known about its ocular manifestations. Still, there are few studies in children and adolescents in this regard and they are inconsistent. However, some evidence suggests a significant role of overnutrition in the development of changes in retinal microvasculature parameters (wider venules, narrower arterioles, lower arteriovenous ratio). Higher values of intraocular pressure were found to be positively correlated with high body mass index (BMI) as well as obesity. In addition, the retinal nerve fiber layer (RNFL) values seem to be lower in obese children, and there is a significant negative correlation between RNFL values and anthropometric and/or metabolic parameters. Changes also could be present in macular retinal thickness and choroidal thickness as well as in the retinal vessel density in children with obesity. However, these associations were not consistently documented. The purpose of this review is to present the most current issues on child obesity and the related potential ocular effects through an overview of international publications from the years 1992-2022.

Abstract
Abstract
Background
Childhood obesity was associated with retinochoroidal microvascular changes using optical coherence tomography angiography (OCTA), but obesity duration was neglected. Obesity is chronic and progressive and obesity duration is related to microvascular function. Thus, it is important to identify microvascular changes in obese children timely to allow possible interventions with the increase in the number of obese children. This pilot study aimed to characterize retinochoroidal microvascular changes in newly developed obese children compared to age- and sex-matched controls.
Methods
Forty newly developed obese children and 40 age- and sex-matched controls were recruited. All subjects completed comprehensive eye examinations, including axial length, cycloplegic refraction, optical coherence tomography angiography scans (AngioVue; Optovue Inc), etc.
Results
There were no statistically significant differences between groups in terms of month age (P = 0.927), spherical equivalent refraction (P = 0.753) and axial length (P = 0.196). Newly developed obese children had lower vessel density (VD) in the inferior parafovea (P = 0.026), nasal parafovea (P = 0.038) and temporal perifovea (P = 0.026) of deep vascular complex (DVC), higher VD in the fovea of superficial vascular complex (P = 0.021) and the fovea of DVC (P = 0.016), and smaller foveal avascular zone (P = 0.003) when compared to controls. Also, no apparent differences in any quadrant of total retinal thickness, subfoveal choroidal thickness (SFCT), and choriocapillaries fow voids were detected (all P > 0.05).
Conclusion
Retinochoroidal microvascular changes had already occurred in newly developed obese children, so early screening and close follow-up eye examinations were recommended; Retinal microvascular insult may precede its structural change and that retina may be a better candidate to predict the onset of retinochoroidal microvascular changes than choroid in obese children.

Abstract
Background Previous studies proposed possible applications of spectral-domain optical coherence tomography (SD-OCT) measurements in prognosticating pathologies observed in overweight/obesity, including ocular, vascular, and neurologic consequences. Therefore, we conducted a systematic review and meta-analysis to investigate the changes in the in SD-OCT measurements of the patients with higher body mass index (BMI) compared to normal weight individuals. Materials and methods We conducted a systematic search on PubMed, Scopus, and Embase. The search results underwent two-phase title/abstract and full-text screenings. We then analyzed SD-OCT measurements differences in patients with high BMI and controls, and performed meta-regression, sub-group analysis, quality assessment, and publication bias assessment. The measurements included macular thickness, cup to disc ratio, ganglion cell-inner plexiform layer (GC-IPL) and its sub-sectors, RNFL and peripapillary RNFL (pRNFL) and their sub-layers, and choroidal thickness and its sub-sectors. Results 19 studies were included in this meta-analysis accounting for 1813 individuals, 989 cases and 824 controls. There was an overall trend towards decreased thickness in high BMI patients, but only two measurements reached statistical significance: temporal retinal nerve fiber layer (RNFL) (Standardized mean difference (SMD): -0.33, 95% confidence interval (CI): -0.53 to -0.14, p<0.01) and the choroidal region 1.0 mm nasal to fovea (SMD: -0.38, 95% CI: -0.60 to -0.16, p<0.01). Conclusion Some ocular layers are thinner in patients with higher BMI than the controls. These SD-OCT measurements might correlate with adverse events related to increased body weight and have prognostic abilities. As SD-OCT is a robust, rapid and non-invasive tool, future guidelines and studies are needed to evaluate the possibility of their integration into care of the patients with obesity.

Longitudinal Effect of Bariatric Surgery on Retinal Microcirculation and Target Organ Damage: the BASTOD Study. Obes Surg 2022; 32:1-10. [PMID: 35469081 DOI: 10.1007/s11695-022-06064-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/02/2021] [Revised: 04/08/2022] [Accepted: 04/13/2022] [Indexed: 11/29/2022]
Abstract
PURPOSE Obesity is associated with increased cardiovascular risk. Bariatric surgery (BS) improves the clinical and metabolic profile. Retinal caliber changes could precede cardiovascular events. Different studies have shown an improvement in retinal caliber after BS. The aim of this study was to examine retinal caliber and other cardiovascular target organ damage before and after BS. MATERIALS AND METHODS Monocentric, prospective cohort study at the Montpellier University Hospital. Biologic features, vessel stiffness, echocardiograph variables, and retinal caliber at baseline and 6 and 12 months were assessed in consecutive patients with class 2 or 3 obesity undergoing BS. A mixed linear model adjusted for age and sex was used. RESULTS We included 88 patients (75 women). The mean (SD) age was 43 years (11) and mean (SD) baseline weight 117 (21) Kg. Mean changes in the first year after BS were - 5.1 µm in central retinal vein equivalent (CRVE) (p < 0.0001), + 0.02 in arteriole-to-venule ratio (AVR) (p < 0.0001), - 1.4 mmol/L in glycemia (p < 0.0001), - 1.0 mg/L in natural logarithm of C-reactive protein (p < 0.0001), and - 54.0 g in left ventricular mass (p = 0.0005). We observed no significant improvement in arterial stiffness markers. Predictors of improvement in CRVE were high baseline weight (p = 0.030), male sex (p = 0.025), and no diabetes history (p Dynamic links between variations = 0.047). CONCLUSION The retinal microvascular phenotype improved during the first year after bariatric surgery, with decreased CRVE and increased AVR. Factors associated with retinal microvascular plasticity were male sex, high baseline weight, and absence of diabetes. Longitudinal assessment of retinal vascular calibers may offer new insights into the pathophysiology of subclinical vascular processes.

Abstract
OBJECTIVE To evaluate changes in retrobulbar ocular blood flow parameters by using Colour Doppler Imaging (CDI) and changes in foveal microvasculature by using Optical Coherence Tomography Angiography (OCTA) in pediatric obese patients and to compare them with a group of healthy children. METHODS Children diagnosed with obesity without hypertension and diabetes (39 subjects, obese group) and age-matched healthy controls (26 subjects, control group) underwent CDI and OCTA imaging. Peak systolic velocity, end-diastolic velocity and resistivity index from ophthalmic, central retinal and posterior ciliary arteries on CDI; superficial and deep capillary plexus vascular density and foveal avascular zone area on OCTA imaging were obtained in each group. Central foveal and subfoveal choroidal thicknesses were also measured. CDI and OCTA parameters were compared between two groups. RESULTS Peak systolic and end-diastolic velocities were found to be significantly lower in obese children than in controls in all three examined arteries (p < 0.05). Resistivity index values were similar between the groups. OCTA imaging did not reveal significant changes in superficial and deep capillary plexus vascular densities and foveal avascular zone area across analysed retinal regions between the groups. Subfoveal choroid was thicker in obese group than in control group (325.89 ± 52.77 µm vs. 304.52 ± 21.76 µm, p = 0.04). CONCLUSION An apparent decrease was present in retrobulbar hemodynamics in obese children. This arises the possibility of early ocular macrovascular compromise rather than retinal microvascular impairment in childhood obesity.

Abstract
Purpose The purpose of this study was to investigate a confocal scanning laser ophthalmoscopy (cSLO) ultra-widefield (UWF) swept-source optical coherence tomography (S-SOCT) in assessment of diabetic choroidopathy and to evaluate the agreement of measurements with a spectral-domain OCT (SD-OCT) instrument. Methods We conducted a cross-sectional study of patients with diabetes evaluating the choroidal vascularity index (CVI) in the nasal, temporal, and central macula segments of a UWF SS-OCT scan centered to the fovea. UWF pseudocolored fundus images were used for diabetic retinopathy (DR) severity staging. The CVI values were compared between different degrees of severity of DR and different posterior-pole sectors with linear mixed models. Central macula CVI measurements were repeated on SD-OCT scans; the interobserver intraclass coefficient (ICC) was calculated between SS-OCT and SD-OCT. Results A total of 151 eyes of 85 patients were included. The CVI values decreased from nonproliferative DR to proliferative DR, with high-risk proliferative DR having significantly lower CVI values than moderate to severe nonproliferative DR (P = 0.03). The central macula region was the most evidently affected; the nasal sector was the least affected. The agreement between SS-OCT and SD-OCT was moderate (ICC = 0.50). Conclusions Diabetic choroidopathy progresses with worsening of DR toward proliferative disease; choroidal depletion is more prominent in the macula. Caution is recommended in comparing CVI values between different devices. Translational Relevance Choroidal vascularity informs about the severity of DR and its complications, such as macular edema. The agreement between readers and between instruments may be suboptimal in certain cases.

Abstract
Introduction Being underweight (body-mass index < 18.50 kg/m2) is associated with significantly higher morbidity than having normal weight. We aimed to investigate the changes in choroid and retinal capillary microcirculation with optical coherence tomography angiography in underweight female subjects compared with an age- and sex-matched population of healthy subjects. Methods This prospective, cross-sectional study included 48 eyes of 48 healthy female subjects, of whom 23 were underweight and 25 had normal weight. Optical coherence tomography angiography was used for the evaluation of retinal vessel density, foveal avascular zone, subfoveal central macular thickness, subfoveal choroidal thickness, and choriocapillaris flow area. Results The mean choriocapillaris flow area was statistically significantly higher in the underweight group (2.201 ± 0.11 mm2) compared to the control group (2.111 ± 0.11 mm2) (p=0.005). The subfoveal choroidal thickness was higher in the underweight group (340 ± 61.2 µm) compared to the control group (317 ± 20.8 µm) but the difference was not statistically significant (p=0.099). Similarly, no statistically significant difference was determined between the groups concerning the vessel density, subfoveal central macular thickness, and foveal avascular zone. Conclusions Being underweight is associated with a higher subfoveal choroidal thickness and choriocapillaris flow area, independent of additional factors, such as age, axial length, intraocular pressure, and major ocular diseases.

Abstract
BACKGROUND Cardiovascular diseases (CVD) are the leading cause of death worldwide. The observability of retinal vessel changes in the context of CVD by funduscopy has been known for a long time. Optical coherence tomography angiography (OCTA) is a novel technique for noninvasive detailed imaging and quantification of the retinal microcirculation. The OCTA enables the visualization of vascular changes in a simple and well-reproducible way. Its applications are not limited to the field of ophthalmology. In recent years, several experimental and clinical studies have been published on vascular changes detectable with OCTA in CVD. This review summarizes the most important findings of these studies. METHODS This work is based on a comprehensive review of the literature and on the presentation of own data. RESULTS Nowadays, OCTA studies are available for many diseases of the cardiovascular spectrum. This indicates that systemic vascular diseases are associated with changes in the retinal microcirculation. These changes can be visualized and reproducibly quantified with OCTA. In many diseases subclinical changes, which are detectable by OCTA, occur before the underlying disease causes otherwise measurable changes or noticeable symptoms for the patient. CONCLUSION The OCTA is a promising imaging method in the context of CVD in both scientific and clinical applications. It can be used for the diagnostics and quantification of retinal vascular changes. Further studies will show whether OCTA can be of assistance in the estimation of individual systemic cardiovascular risk profiles.

Abstract
OBJECTIVE Regarding the effect of obesity on subfoveal choroidal thickness (CT) and peripapillary retinal nerve fiber layer (RNFL) thickness, controversial results have been reported in different patient groups. This study aimed to evaluate the effect of obesity on these parameters among young male subjects in comparison with age-matched non-obese healthy males. METHODS This prospective, cross-sectional study included both eyes of 50 obese young males and 50 healthy non-obese young males. The obese and the non-obese groups included subjects with a BMI of ⩾30 and ⩽25 kg/m², respectively. Subfoveal choroidal thickness and RNFL analyses were conducted by spectral domain optical coherence tomography (SD-OCT). RESULTS Subfoveal choroidal thickness (321.0 ± 46.7 vs 338.4±35.3, p = 0.002) and RNFL thickness at temporal quadrant (73.4 ± 9.9 vs 76.4 ± 9.3, p = 0.008) was significantly lower in the obese group when compared to the non-obese group. The groups did not differ regarding peripapillary RNFL thickness at other quadrants (superior, inferior, or nasal) or regarding mean peripapillary RNFL thickness. CONCLUSION Findings of this study demonstrated a negative correlation of obesity with subfoveal choroidal thickness and temporal quadrant peripapillary RNFL thickness. Larger studies on different patient groups with longer-term follow-up are warranted to better elucidate the ophthalmological effects of obesity.

Abstract
BACKGROUND There is paucity of data on ocular changes in acute Pancreatitis (AP). Moreover, subclinical alterations in retina & choroid have not been studied in AP. OBJECTIVE To prospectively study retino-choroidal changes in AP. METHODS Sixty patients (mean age 39.07 years; 41 males) with AP were followed up till recovery/death. Baseline slit-lamp examination, choroidal thickness (CT), retinal thickness (RT), choroidal vascularity index (CVI), retinal capillary density index (CDI) and arteriovenous ratio (AVR) were recorded. The patients were divided into two groups - mild (Group A; 5 patients) and moderately severe/severe (Group B; 55 patients) as per revised Atlanta classification. RESULTS Fundus examination showed mild optic disc edema with retinal hemorrhages in 6 (10%) patients in group B as compared to none in group A (p = 1.00). None of the patients had Purtscher retinopathy. Mean CT (317 ± 56.29 μm) was increased as compared to normal subjects (278.90 ± 57.84 μm, p = 0.003). The mean CVI (0.62 ± 0.04) was decreased as compared to normal (0.66 ± 0.01, p < 0.0001) as was the mean AVR (0.67 ± 0.03 vs. 0.7 ± 0.02, p < 0.0001). However, the mean RT of subjects with AP (239.68 ± 33.76 μm) was not significantly different compared to the normal subjects 253.17 ± 33.67 µm (p=NS). The mean CDI of superficial and deep plexus were comparable between normal and patients with AP. CT, RT, CVI, AVR and CDI were comparable between group A and group B as well as survivors and non-survivors. CONCLUSIONS Clinically significant ocular changes are seen infrequently in AP. However, subclinical changes in CT, CVI and AVR are observed in patients with AP compared to normal individuals.
