| Summary: | The aim of this prospective study was to determine changes in central macular thickness
in the early postoperative period after uncomplicated phacoemulsification cataract surgery in diabetic
patients using spectral domain optical coherence tomography (SD-OCT). Uncomplicated ultrasound
phacoemulsification cataract surgery causes minimal changes of retinal layer thickness, which may result
in subclinical cystoid macular edema development. This prospective study included 55 patients divided
into two groups. Group 1 included diabetic patients with cataract, and group 2 included patients with
cataract and without diabetes. All patients underwent uncomplicated ultrasound phacoemulsification
cataract surgery at the Department of Ophthalmology, University Hospital Osijek in the period from
November 2017 to January 2018. Patients were followed-up for one month after surgery. At each examination,
OCT recording of the eye undergoing cataract surgery was performed. A statistically significant
difference in central macular thickness in the diabetic group and control group (p=0.0005 both) was confirmed
preoperatively and one month after cataract surgery. A statistically significant difference in central
macular thickness was confirmed in diabetic group (p=0.006), as well as in the control group of patients
(p=0.01) seven days and one month after cataract surgery. There was no statistically significant difference
in macular thickness changes between the diabetic and control group of patients preoperatively (p=0.618),
seven days (p=0.6848) or one month after cataract surgery (p=1). The effect of HbA1c on macular thickness
change in diabetic patients was not statistically significant. The mean HbA1c in diabetic patients was
7.24±1.34%. There was no statistically significant difference in the effect of cumulative dissipated energy
on macular thickness change in either group. This study confirmed a statistically significant correlation
of the effect of fluid volume consumption on macular thickness changes in diabetic patients. There was
no statistically significant effect of fluid volume consumption on macular thickness change in the control
group of patients. Uncomplicated ultrasound phacoemulsification cataract surgery caused changes in central macular thickness in the early postoperative period in both patient groups. Changes in central macular
thickness in the observed period were not manifested with clinically significant macular edema or by a
more significant decrease in visual acuity. All patients had significant improvement in visual acuity seven
days and one month after cataract surgery. |
