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