Objective: To overcome the backlog of cataract and to accept challenge of new
cases N.G.Os are playing major role. The purpose of this study is to ensure
the quality of clinical and surgical services provided to the patients and to
analyze patient satisfaction index. Method: The audit is a regular feature of our
outreach programme. It is done by a senior Ophthalmologist not associated
with day to day functioning of the hospital by random selection method and by
patient care department.10% of operated patients are evaluated every year.
Results: Vision acuity classification is done as per W.H.O. criteria.88% patients
were having good vision.100% patients were satisfied about hospital services
and negligible % age of patients were having complaints like watering.
Conclusion: Medical field audit and patient care audit is a very effective tool to
maintain the quality in community outreach program. Patients give good feed
back in their own environment. It helped us to judge socioeconomic impact of
our program and to improve some of the systems.

Objective: The aim of the study was to determine the correlation between
pulsatile ocular blood flow (POBF) and sleep apnoea syndrome (SAS).
Methods: A total of 52 Caucasian patients, 34 with SAS and 18 age- and
gender-matched controls, were included in the study. Comprehensive
ophthalmic examination included the pulsatile ocular blood flow (POBF)
measurements, disc analysis with HRT II and Oculus computerized perimetry
as well as the best visual acuity, a slit lamp and indirect ophthalmoscopic
evaluation of anterior and posterior segments and applanation tonometry.
Results: The observed prevalence of glaucoma in SAS patients was 5.9%. The
mean values of POBF were 1069.21 ±235.94 µl/min in the SAS group and
1061.78 ±174.63 µl/min in the control group. The study revealed that the
differences of mean POBF between the SAS patients and the control group
were not statistically significant: Mann-Whitney U-test p > 0.05. No correlations
were found between sleep apnoea syndrome and mean intraocular pressure
(IOP), mean retinal nerve fibre layer (RNFL) thickness and visual field mean
defect (MD).
Conclusions: No correlation was found between pulsatile ocular blood flow and
sleep apnoea syndrome. However, a high prevalence of glaucoma was found
among SAS patients in Poland.

Objective & Purpose: The aim was to identify presence of diabetic retinal (DR)
changes in nephropathy (DN) subjects and observe the association with blood
pressure, proteinuria and dyslipidemia
Methods: Pre diagnosed 215 DN subjects with diabetes duration ?5 years
were included and evaluated for clinical and laboratory parameters. Fundal
evaluations were done by +78-D double-aspheric fundus lens and a calibrated
slit lamp. Central 300 of the fundus was observed and complications recorded
as per modified ETDRS criteria
Results: DR changes were absent in 76% and present in 24% patients (nonproliferative
(NPDR) 5% and proliferative (PDR) 19%). Maculopathy (MAC) was
seen in 12% and hypertensive eye changes (HTE) 17% patients. Comparisons
between DR +ve vs. DR -ve subjects showed diabetic and renal parameters
were similar in both groups (SCr 2.4±0.6 vs. 1.9±0.7 mg/dl; UTP 1.3±1.7 vs.
1.1±1.3 g/d; HbA1c 7.5±1.6 vs. 7.4±1.1% and CCR 44±30 vs. 50±30 ml/
min/1.73m2; P=NS). Also NPDR and maculopathy +ve vs. -ve showed no
difference. Renal function was worse in PDR +ve (CCr 41±20) and HTE +ve
group (CCr 36±15) than the -ve subjects (CCr 51±31) (p
