“…In our study, the DC of eyes with severe ptosis was significantly larger than that of eyes without ptosis, which is in accordance with the findings of previous studies [ 3 , 4 , 5 , 6 , 8 ]. Kim et al [ 4 ] found that a decrease in MRD1 and an increase in body mass index were associated with higher astigmatism.…”

“…In our study, the differences in preoperative SE between the different severity groups were not statistically significant, which is similar to the findings of some [ 29 , 32 ], but not all, studies [ 3 , 4 , 5 , 7 ].

“…Hoyt et al [ 7 ] reported monocular axial myopia of the affected eye in eight infants (age range: 7 weeks to 19 months) with neonatal eyelid closure. In a cross-sectional study ( n = 33,103, age distribution from <20 years to >60 years), Kim et al [ 4 ] reported hyperopic shift in ptotic eyes compared to non-ptotic eyes. An increased risk of developing myopia, as well as hyperopia, has been found in children with ptosis [ 5 ].…”

“…Congenital ptosis, defined as an abnormally low position of the upper eye lid at birth, may be simple or associated with other congenital conditions, such as Marcus Gunn syndrome, blepharophimosis, or congenital third cranial nerve palsy [ 1 ]. Congenital ptosis is known to be associated with refractive error and abnormal visual development [ 2 , 3 , 4 , 5 , 6 , 7 , 8 ]. Patients with ptosis tend to have a larger degree of astigmatism in the ptotic eye than in the non-ptotic eye [ 2 , 4 , 9 ], in addition to significant differences in corneal topography between the ptotic and non-ptotic eye [ 4 , 10 , 11 , 12 , 13 , 14 ].…”

A common indication for early surgical correction of congenital ptosis is the prevention or treatment of amblyopia, which may be due to obstruction of the visual axis and associated significant refractive error.…”

Background and objectives: Previous studies on ptosis recurrence after correction surgery have tended to focus on postoperative complications, surgical methods and suspension materials, few have mentioned refractive error. This research is to investigate the potential relation between refractive error and recurrence after correction surgery in pediatric patients with simple congenital ptosis. Materials and Methods: We conducted a retrospective analysis of data from patients with simple congenital ptosis who were treated at Zhongshan Ophthalmic Center (ZOC) between 2017 and 2020. In total, 111 eyelids of 85 patients without surgery-related complications who underwent frontalis muscle flap suspension (FMFS) for simple congenital ptosis were included. Postoperative changes in eyelid height were assessed. Cycloplegic refraction was assessed before surgery and during the follow-up period (every 3 months after surgery). Recurrence in the postoperative period was defined as a marginal reflex distance 1 (MRD1) of <1 mm. Results: There were 16 recurrence and 69 non-recurrence cases, with no statistically significant differences, in terms of patient age at the time of surgery, patient sex, or preoperative MRD1, between the recurrence and non-recurrence groups. The postoperative cylindrical diopter (adjusted odds ratio [OR] = 0.432, p = 0.005), laterality (adjusted OR = 0.202, p = 0.006), and preoperative MRD1 (adjusted OR = 0.617, p = 0.019) were associated with ptosis recurrence after surgery. Differences between the recurrence and non-recurrence groups in spherical diopter and spherical equivalent (SE) before and after surgery were not statistically significant. In addition, preoperative refractive error and postoperative spherical diopter were not significantly associated with ptosis recurrence after correction surgery. Conclusions: Ptosis recurrence after FMFS in pediatric cases of congenital ptosis is associated with refractive error. Timely refractive correction and amblyopia treatment may help to reduce ptosis recurrence.

Purpose: To investigate the change of corneal astigmatism after the correction of blepharoptosis. Methods: This was a single-center retrospective cohort study conducted in Taiwan from 2017 to 2021. The medical records of patients with acquired blepharoptosis who had received levator muscle surgeries were collected. The differences in corneal astigmatism between the measurements before and at least 1 month after surgeries were investigated. Subgroup analysis of various severities of blepharoptosis and different types of corneal astigmatism was performed to determine their impacts on the axial changes after blepharoptosis surgeries. Results: A total of 120 eyes of 68 patients were enrolled in this study. The mean axial change of corneal astigmatism was 17.4° after blepharoptosis surgeries, and 55 eyes (45.8%) had a change of at least 10°. In the subgroup analysis, the eyes with against-the-rule, with-the-rule, and oblique astigmatism had 42.9%, 68.4%, and 91.7% with an axial change of at least 10° after surgeries, respectively. The averaged axial change of corneal astigmatism after surgeries was 22.7° in eyes with severe blepharoptosis (margin to reflex distance1 < 1 mm), whereas it was 12.0° in eyes with mild-to-moderate blepharoptosis (margin to reflex distance1 ≥ 1 mm). Conclusions: A high proportion of eyes had a crucial axial change in corneal astigmatism after blepharoptosis surgeries, especially in those with oblique astigmatism and severe blepharoptosis. For blepharoptosis patients needing refractive surgeries or astigmatism correction with toric intraocular lens implantation, a surgical correction of blepharoptosis may be considered beforehand.

Corneal biophysical changes after upper eyelid blepharoplasty and ptosis surgery: a review

et al. 2023

View full text Add to dashboard Cite

Upper eyelid surgeries, such as blepharoplasty and ptosis correction, are commonly performed procedures worldwide. This review examines the effects of these surgeries on ocular properties and visual function. A search of the PubMed and Google Scholar databases was conducted to identify relevant articles published after 2000. The results demonstrate that the ocular and adnexal organs function as a unified visual system, with changes in one component affecting the functions of others. Eyelid surgery can alter ocular properties and functions by modifying retinal lighting and ocular optics. These alterations can affect intraocular pressure estimation, corneal curvature, corneal epithelial thickness, refractive power of the cornea, and intraocular lens calculation. Additionally, eyelid surgery can exacerbate dry eye symptoms and impact contrast sensitivity, which is a significant factor in visual quality. Therefore, understanding these interactions is crucial before performing eyelid surgery and during follow-up. This review summarizes recent literature on the effects of upper eyelid surgery on corneal properties and visual function, emphasizing the importance of considering these factors when planning or undergoing such procedures.
