Abstract Details

Purpose:

To evaluate the macular thickness by optical coherence tomography (OCT) in patients with or without diabetes mellitus after uncomplicated phacoemulsification surgery and intraocular lens implantation.

Setting:

İzmir Atatürk Education and Research Hospital, Turkey

Methods:

The cases included in this retrospective study were those having already had cataract surgery, 35 of them with no diabetes (Group 1) and 30 cases matched in terms of age and gender with diabetes (Group 2). The inclusion criteria of patients with diabetes was defined as the absence of any diabetes related ophthalmoscopic findings. Demographic data and ocular examination findings of the patients were recorded. Preoperative and postoperative central macular thickness (MT), as well as the 3 mm and 6 mm of superior, inferior, nasal and temporal quadrant MT values were evaluated by OCT and compared statistically.

Results:

The mean ages of Group 1 and Group 2 were 66.05±10.63 and 68.13±8.85 years, respectively. Postoperative central MT was statistically higher in Group 1 only in the 1st month, whereas higher in Group 2 in the 1st, 3rd and 6th months. Three mm MT in all quadrants were statistically higher in Group 1 in the 1st and 3rd months, in Group 2 they were higher in the 1st, 3rd and 6th months. Six mm MT in all quadrants were statistically higher in Group 1 in the 1st month, while in Group 2 in the 1st and 3rd months.

Conclusions:

Subclinical macular edema after cataract surgery can be detected by diagnostic instruments like OCT. Care should be taken in diabetic cases, particularly due to the reason that cataract surgery can increase the probability of cystoid macular edema. It is essential to use OCT in the diagnosis of cystoid macular edema that may develop after cataract surgery and in the follow-up of the treatment
