OBJECTIVE: To determine if non-insulin dependent diabetes mellitus
(NIDDM) or insulin dependent diabetes mellitus (IDDM) impacts upon the
development of cystoid macular edema (CME) after ganciclovir implant
(Vitrasert) surgery. DESIGN: Retrospective study. METHODS: The records
of 54 patients (76 eyes) who had previously received ganciclovir
implants were analyzed (98 procedures performed). Patients were divided
into three groups: those having insulin dependent diabetes mellitus
(IDDM), those having non-insulin dependent diabetes mellitus (NIDDM),
and those not having diabetes (groups 1, 2, and 3). All patients
received identical postoperative medications and had the implants placed
using the same, standard surgical technique. All patients had frequent,
full ophthalmic examinations, including indirect ophthalmoscopy and
contact lens examination of the macula. Fluorescein angiography was
performed to determine the status of the macula, if deemed necessary on
examination. RESULTS: Of 54 patients who received ganciclovir implants
between 12/94 and 12/97 (76 eyes), 14 patients (22 eyes) were found to
be diabetic. Six (10 eyes) had IDDM, and 8 (12 eyes) had NIDDM. Four
patients (66%) or 28% of procedures in group 1 developed CME, while 4
(50%) or 30.8% of procedures in group 2 developed CME. Of the 40
non-diabetic patients, 4 (10%) developed CME, or 5.6% of procedures.
There is a statistically significant difference between the groups.
CONCLUSION: IDDM may increase the patient's chance of developing CME
after implant surgery. Careful postoperative assessment of the macula is
warranted, especially in diabetic patients.
