Abstract

Background and Aim: Macular oedema (ME) occurs in a variety of pathological conditions and accounts for different
degrees of vision loss. Early detection of ME is therefore critical for diagnosis and management. Optical Coherence
Tomography (OCT) is particularly useful and accurate for measuring retinal nerve fiber layer (RNFL) thickness and
macular thickness. This study is undertaken to evaluate the quantitative changes in macular thickness using spectral
domain optical coherence tomography in diabetic patients undergoing cataract surgery pre and post operatively and its
relation with diabetic retinopathy.
Material and Methods: Study participants included 100 diabetic patients irrespective of presence or absence of retinopathy
who underwent cataract surgery. Each eye underwent fundus examination with indirect ophthalmoscopy and OCT of
macula i.e.,preoperatively and at postoperatively at day 1, 1 week, 4 weeks and at 12 weeks. Best-corrected visual acuity
(BCVA) was recorded at each visit.
Results: Visual acuity improved postoperatively at 4th and 12th week after small incision cataract surgery to 6/12 and 6/9
in majority of the patients. Post operatively 1 month 75% patients achieved vision of 6/6– 6/12. Mean values of central
subfield macular thickness at preoperatively was 268.9 μm which increased to 278.2 μm at postoperative day 1, 281.6 μm
at postoperative 1 week, 286.1 μm at postoperative 4 weeks and 297.2 μm at postoperative 12 weeks.
Conclusion: There was no difference in median macular thickness between the groups, and no cases in either group had
an increase in macular thickness to reach this threshold. diabetic macular edema generally worsens after cataract surgery,
and that the worsening of macular edema is more prominent in eyes with DR.
