Findings confirmed the reversibility of macular thickness changes 6 months after cataract surgery and its return to preoperative values.
This prospective follow-up study evaluated the longer term changes to macular thickness and volume following cataract surgery. The study included 23 patients (23 eyes) who underwent ambulatory cataract surgery with phacoemulsification and intraocular lens implantation, followed by a scheduled optical coherence tomography measurement of macular thickness and volume after 3 months. Results were compared with preoperative data and measurements taken at 1 month after surgery, which were recorded in a previous study. A comparison of preoperative macular thickness values with those at 3 months after surgery demonstrated that the latter values remained greater in all macular regions except the superior outer macula, and that the differences were significant in the fovea, nasal inner macula and inferior outer macula. When macular thickness at 3 months after surgery was compared with that measured at 1 month, decreases were observed in all perifoveal areas, suggesting the reversible nature of cataract surgery-related macular thickness changes.
This observational study was designed to compare corneal thickness in patients with age-related macular degeneration (AMD) with the thickness in healthy control subjects to determine if there is a correlation between corneal thickness and the development of AMD. A total of 69 patients (119 eyes) with AMD and 31 healthy subjects (56 eyes) were evaluated. Corneal thickness was measured with a Galilei Dual Scheimpflug Analyser and retinal thickness was measured using optical coherence tomography. There was no significant difference in mean corneal thickness or mean retinal thickness between the AMD and control groups and no correlation between corneal and retinal thickness in either group. The results confirmed that corneal thickness is not associated with the development of AMD and cannot be used during diagnosis.
Zusammenfassung Ziel Das Ziel unserer Studie war es, mögliche Netzhautveränderungen bei den mit Chloroquinphosphat behandelten SLE-Patienten (SLE: systemischer Lupus erythematodes) festzustellen und zwar in Bezug auf die Behandlungsdauer. Methoden In die Studie wurden 41 SLE-Patienten (82 Augen) eingeschlossen, die mit Chloroquinphosphat oder Hydroxychloroquinphosphat behandelt werden und bei denen noch keine Netzhautpathologie diagnostiziert worden ist. Studienteilnehmende wurden entsprechend der Behandlungsdauer in 2 Gruppen eingeteilt. Die 1. Gruppe umfasste 18 Patienten (36 Augen), die einer bis zu 5-jährigen Behandlung unterzogen wurden, und die 2. Gruppe bestand aus 23 Patienten (46 Augen), die von 5 – 20 Jahren behandelt wurden. Es wurde eine gründliche Augenuntersuchung durchgeführt, einschließlich bestkorrigierter Sehschärfe, Farbsehen, Gesichtsfelduntersuchung, Fundusuntersuchung bei dilatierten Pupillen, Autofluoreszenzuntersuchung, Fundusfotografie und Spectral-Domain optische Kohärenztomografie (SD-OCT). Ergebnisse Die durchschnittliche Behandlungsdauer der 1. Gruppe betrug 2,79 ± 1,37 Jahre, während die 2. Gruppe im Durchschnitt 8,67 ± 2,26 Jahre behandelt wurde. Der Unterschied in der zentralen Netzhautdicke zwischen den beiden Gruppen war statistisch insignifikant (p > 0,05). Der Vergleich der parafovealen Dicke zwischen den beiden Gruppen war in allen Regionen statistisch insignifikant (p > 0,05). Gesichtsfelduntersuchung, Autofluoreszenzuntersuchung und Fundusfotografie waren ohne nennenswerte Pathologie. Schlussfolgerung Unsere Ergebnisse zeigen keine statistisch signifikanten Veränderungen in der Netzhautstruktur zwischen den beiden Gruppen und in Bezug auf die Behandlungsdauer. Infolgedessen kann man schließen, dass jährliche Nachuntersuchungen dieser Patienten sicher genug sind, um mögliche präklinische Makulopathie festzustellen.
Purpose The goal of this study was firstly to compare corneal thickness at four different locations, anterior depth and pupil diameter between patients with neovascular age‐related macular degeneration and healthy individuals and secondly, to find out any possible anterior segment related risk factor for AMD development. Methods In this prospective study 69 patients (119 eyes) with neovascular age‐related macular degeneration with no history of any ocular disease or surgery were included. The 31 controls (56 eyes) were also enrolled. Informed consent was obtained from all recruited individuals. Each subject underwent complete ophthalmic examination. Galilei Dual Scheimpflug Analyzer (version 3.0, Ziemer Ophthalmic Systems AG, Switzerland), a non‐invasive diagnostic system designed for analysis of anterior chamber of the eye, was used for anterior segment evaluation. Results Comparison of corneal thickness at central, paracentral, peripheral zone and at the thinnest point revealed no statistically important difference between patients with age‐related macular degeneration and controls (P<0,5). There was a statistically significant difference in the mean anterior chamber depth between both groups (P=0,002). We did not observe statistically important difference in pupil diameter between both group (P>0,5). Conclusion The results of our study confirmed that the corneal thickness and pupil diameter are not associated with age‐related macular degeneration. Further investigations are necessary to confirm our results and to find out a possible role of anterior chamber depth as an additional risk factor for AMD development.
