Standard 20G vitrectomy was done for all cases with membrane peeling,<br />
endolaser photocoagulation, trans scleral cryotherapy and fluid air exchange<br />
done wherever necessary and tamponading agents like silicon oil, C 3<br />
F 8<br />
and SF 6<br />
were used appropriately. On the first post-operative day, the anterior segment<br />
and fundus findings including oozing spots, dispersed hemorrhage, retinal<br />
detachments etc. were analyzed. Recorded findings in the subsequent follow<br />
up visits including best corrected visual acuity, intra ocular pressure, anterior<br />
segment changes raised IOP, like progression of cataract, pupillary distortion<br />
and rubeosis were assessed. Some cases where cataract and filtering surgery<br />
was performed were also analyzed. Anatomical status of the retina which<br />
was recorded using fundus biomicroscopy and indirect ophthalmoscopy and<br />
B scan ultrasonography (where media haze was present) was also analyzed.<br />
Repeat surgery in case of any complication was retrospectively studied. These<br />
parameters were assessed separately for all the groups based on indications<br />
of the surgery and the tamponade used. The mean follow up period was 13.5<br />
months.<br />
RESULTS<br />
Mean age of the patients was 56.84 years. Male to female ratio was 3.7: 2.2.<br />
The mean duration of the diabetes was 19.09 years. Control of diabetes were<br />
assessed using HbA1C status of the patient before the surgery which showed<br />
a 3.77% (6/159) had good control, 83.02% (132/159) had moderate and 13.21%<br />
(21/159) had poor control of diabetes mellitus.<br />
Hypertension was to be highly associated with patients with PDR (65.41%),<br />
12.58% had dyslipidemia and 8.18% were having associated ischemic heart<br />
disease. Nephropathy was seen in 4.4%.<br />
101/159 (63.52%) eyes had Non resolving vitreous hemorrhage with or with<br />
our pre retinal hemorrhage / fibrovascular proliferation as major indication<br />
for vitrectomy. 58/159 (36.48%) eyes had Tractional / combined retinal<br />
detachment with or without vitreous or pre retinal hemorrhage and fibro<br />
vascular proliferation as indication.
