“…They claimed that the inflammatory insult due to phacoemulsification mainly affects at the retinal level and seems to be independent of CT changes 23. By contrast; our results support the recent studies by Ohsugi et al24 and Noda et al,25 which report significant increases in CT after uneventful phacoemulsification. Ohsugi et al24 evaluated 100 eyes and emphasized that the AL and changes in IOP were critical for evaluating the changes in CT after cataract surgery.…”

PurposeWe aimed to evaluate the effect of cataract surgery on subfoveal choroidal thickness (CT) and ganglion cell complex (GCC) thickness, as measured by enhanced depth imaging-optical coherence tomography (OCT).MethodsThis prospective study included 30 eyes of 30 patients who had undergone uneventful phacoemulsification surgery for senile cataract but had no previous ocular surgery or other ocular abnormality. Best-corrected visual acuity, slit-lamp biomicroscopy, intraocular pressure, axial length, and central corneal thickness were measured preoperatively. The operative times (OTs) and effective phaco times were also recorded in each case. OCT measurements were performed at the preoperative visit and 1 month after cataract surgery. Study of CT and GCC thickness changes was the primary objective, but central macular thickness (CMT) and peripapillary retinal nerve fiber layer (RNFL) thicknesses were also obtained by OCT.ResultsThe mean subfoveal CT was 294.4±39.2 μm preoperatively and 301.4±39.9 μm postoperatively (P<0.001). The mean GCC thickness was 85.0±4.4 μm preoperatively and 89.2±5.3 μm postoperatively (P<0.001). The mean CMT was 247.9±17.6 μm preoperatively and 249.0±17.8 μm postoperatively (P=0.029). The mean RNFL thickness was 97.4±5.4 μm preoperatively and 101.7±5.6 μm postoperatively (P<0.001). Regression analysis showed that age, sex, axial length, central corneal thickness, operative time, and effective phaco time were not associated with CT changes (P=0.834, P=0.129, P=0.203, P=0.343, P=0.547, and P=0.147, respectively) and GCC thickness changes (P=0.645, P=0.542, P=0.152, P=0.664, P=0.448, and P=0.268, respectively) after cataract surgery.ConclusionOur results indicate that all subfoveal CT, CMT, as well as RNFL and GCC thicknesses are slightly affected after uneventful phacoemulsification surgery. After cataract surgery, the examiners should consider obtaining new baseline measurements.

“…Ohsugi et al [16] showed that after cataract surgery (in 100 eyes), IOP was significantly lower at 3 weeks, 3 months, and 6 months; the thicknesses of the macular central fovea and lower choroid were significantly increased, and were inversely correlated with IOP increase and ocular axis. Noda et al [21] observed 29 cases undergoing phacoemulsification cataract surgery, and showed that choroidal thickening could be observed for at least 6 months after the surgery. Pierru et al [22] observed 115 eyes that underwent phacoemulsification; choroidal thickness was significantly increased 1 day, 1 month, and 3 months after surgery, and the SFCT was significantly increased after surgery.…”

Purpose: To assess changes in the thickness of the subfoveal retina and choroid after phacoemulsification using enhanced depth imaging optical coherence tomography (EDI-OCT). Methods: A prospective study was conducted on 100 patients. The subfoveal choroidal thickness (SFCT) was measured at 7 points and the retinal thickness was measured at 5 points (before surgery, and 1 day, 1 week, 1 month, and 3 months after surgery). Results: The foveal choroidal thickness showed a thickening trend (but p > 0.05). Compared to the change from baseline to day 1, the changes from baseline were significantly different at nasal 3 mm and 6 mm at all other time points (all p < 0.05). Choroidal thickness changes at temporal 6 mm correlated negatively with intraocular pressure (IOP) at 1 week and 1 month; changes at nasal 3 mm correlated negatively with IOP at 1 week and 1 month (all p < 0.05); changes at nasal 3 mm, temporal 3 mm, and temporal 6 mm correlated with average ultrasonic energy. Choroidal thickness changes correlated with ultrasound (US) time at day 1. Conclusions: Uncomplicated phacoemulsification led to changes in choroidal thickness. IOP and choroidal thickness changes were negatively correlated. The foveal retinal thickness was correlated with age. SFCT was correlated with sex, axial length, IOP, and US time.

“…In our sample, there were not significant differences in CT changes between patients who underwent combined surgery and those who underwent PPV alone ( p > 0.05). These findings are quite unexpected because previous work has shown an increase in subfoveal CT after uncomplicated cataract surgery [35][36][37] . The authors speculated that subfoveal CT increase may be related to the postoperative inflammation because proinflammatory prostaglandins and cytokines are considered to explain macular edema after cataract surgery [38,39] , and inflammatory disorders are also known to increase CT [40,41] .…”

Analysis of Choroidal Thickness Change after 25-Gauge Vitrectomy for Idiopathic Epiretinal Membrane with or without Phacoemulsification and Intraocular Lens Implantation

Purpose: This study aimed to evaluate choroidal thickness modifications before and after vitrectomy with or without phacoemulsification for idiopathic epiretinal membrane in the operated eye and in the unaffected fellow eye. Methods: In total, 53 eyes of 53 patients underwent 25-gauge pars plana vitrectomy plus internal limiting membrane peeling and air tamponade. Twenty-seven eyes underwent combined surgery with phacoemulsification and intraocular lens implantation. Choroidal thickness was measured using enhanced deep image spectral-domain optical coherence tomography at the fovea and at 500 and 2,500 µm from the fovea. Fellow eyes without any previous ocular surgery history served as controls. Results: Baseline comparison did not show significant differences between study and fellow eyes (p > 0.05). Choroidal thickness significantly decreased in the subfoveal area (p = 0.004) as well as at 500 µm (p = 0.026) and 2,500 µm nasally (p = 0.019) and at 500 µm (p = 0.039) and 2,500 µm (p = 0.005) temporally to the fovea. No significant changes were observed postoperatively in the superior and inferior areas (p > 0.05). No differences were found between eyes which underwent combined surgery and those which underwent vitrectomy alone (p > 0.05). The unaffected eyes did not show any significant changes (p > 0.05). Conclusions: Comparison of baseline values did not show any differences between affected and unaffected eyes, meaning that choroidal thickness was not influenced by the development of epiretinal membrane. Vitrectomy plus epiretinal and inner limiting membrane removal may influence choroidal homeostasis, leading to a decrease in choroidal thickness in the subfoveal, nasal, and temporal areas. Combined surgery did not show significant differences when compared to vitrectomy alone.
