Purpose: To assess the frequency of different eye
morbidities in the patients presenting at a tertiary care Hospital in Peshawar. Study Design: Cross sectional study. Place and Duration of Study: Ophthalmology
unit of Rehman Medical Institute (RMI), Peshawar from February 2004 to month of March 2014. Material & Methods: This research involved accessing the data bank kept by the
Hospital. All ocular morbidities seen during the study period was included in
the study while those who presented with the diseases of the eye due to some other systemic condition were
excluded. Patients were categorized according to their gender and year of
admission. The age categories were divided into 5 groups, 0-20, 21-40, 41-60,
61-80, 81-100 years’ category. The data collected was analyzed using MS Excel
2013. Results: A total of 1869 patients were examined out of which 49.92%
were male and 50.07% were female.
The ocular examination revealed that out of the 1869 patients, 57.30% of the
patients suffered from Cataract, 4.86% patients suffered from Pterygium,
4.76% suffered from Strabismus, 1.65% patients suffered from Glaucoma and the
remaining 31.43% suffered from various spectrum of diseases. Female
preponderance was more than males in the sense of general morbidity of ocular
disorders. Conclusion: Cataract was found to be the most common ocular morbidity
found in all age groups. Keywords: Pterygium, Glaucoma, Cataract, Strabismus. |
The
presentation of eye diseases varies widely all over the globe1,2. Specific diseases are common
in certain age brackets, races and occupations.2-4. Early diagnosis is required in most eye morbidities to
prevent loss of sight and to have better prognosis.5 Vision
is essential for daily activities and any visual impairment is serious and
debilitating disability6. While some eye morbidities are easily
cured and others if not prevented or treated promptly can lead to loss of
vision and permanent blindness, therefore it is of paramount importance to find
out the trend of eye diseases7. Large amount of data is available on
anticipation and treatment of the visual deficiency in every single remote
district of the World, yet almost no data is accessible on the pervasiveness of
visual ailments in Tibetan who live in the remote zones of the Tibetan Plateau8.
The
prevalence of visual impairment is expected to be higher in the developing
countries due to the low level of healthcare services in many of the countries9.
Prevalence mapping
concerning the weight of a condition (e.g., visual debilitation) at a specific
area at a point or period is essential. Accurate prevalence gauges are expected
to help in the accessibility of human services, related financial expenses, and
personal satisfaction associated with having the condition. Information of such
caliber is a basic part in arranging future investigations, having controlled
clinical preliminaries in anticipation and appropriate treatment of the
morbidity.
Currently there is very little data on the
prevalence of eye diseases in the north western part of Pakistan The purpose of
this research was to discover the pattern of eye ailments in ophthalmology department
of Rehman Medical Institute Peshawar.
MATERIAL & METHODS
A
descriptive retrospective study was done of patients visiting the Ophthalmology
unit of Rehman Medical Institute Peshawar from February 2004 to March 2014 by
accessing the registers kept by the Hospital. Patients were categorized
according to their gender and year of admission. The age categories were
divided into 5 groups, 0-20, 21-40, 41-60, 61-80, 81-100 years category. A total
number of 1869 patients were found during the ten-year retrospective study.
All
patients aged 1-100- years who were admitted in ophthalmology department in RMl
Peshawar, having ocular morbidity were included in the study while those
presenting with diseases of the eye along with other systemic diseases were
excluded.
The
Data collected was analyzed using MS Excel 2013. After the collection of data,
all the data was entered into MS Excel 2013 and the analyzed results
are presented as simple frequencies and tables. The data analyzed was based on
the number of patients admitted to the Eye unit and the variables under study included
major diagnoses i.e. Cataract, Glaucoma, Strabismus and Pterygium.
RESULTS
The
investigation revealed that out of the 1869 patients 49.92% were male and 50.07% were female. 57.30% of the patients suffered from
Cataract, 4.86% patients suffered from Pterygium, 4.76% suffered from
Strabismus, 1.65% patients suffered from Glaucoma and the remaining 31.43%
suffered from various other diseases (Table 1 and 2).

The third age group i.e. 41 – 60 years presented with the highest proportion of
diseases (38.80%), while above 81 years group accounted for the least
proportion of disease i.e. 1.87% patients (Table 3). Cataract was the most
common disease found in all age groups of patients.

DISCUSSION
The
major ocular morbidity observed in the study was Cataract with 1071 patients
i.e. 57.3%. Females (51.73) were more affected than males (48.08). The age
group most affected was 41-60 years with 452 patients (42.24%) of all cataract
cases. Quite similar results were found in a study conducted by Ahmed et al. at
Hayatabad medical complex Peshawar where cataract accounted for 57.5% patients10.
Opacification
of the crystalline lens of the eye causes total or partial blindness11.
Cataract is the leading cause of loss
of vision and blindness worldwide and is prevalent in both developed and
developing countries.\12 Cataract, in fact being highly treatable
with minimally invasive surgeries, still accounts for half the world’s cases of
reversible blindness. In most developing
countries, blinding cataract is not only prevalent but is also more severe.
And, unfortunately, the curative operative procedures are insufficient13.
A Pterygium (from the
Greek, pterygos, “little wing”) is a wing-shaped, fibrovascular growth
that originates from the bulbar conjunctiva and that can chronically spread to
the corneal limbus and beyond14,15. The total number of cases with
pterygium in our study were 91 out of which 58.24% were males and 41.76% were
females. The age group most affected was 21-40 years with 50.06% patients. In
another study held in Barbados, the prevalence rate was 11.6%16. Yet
another study showed a prevalence rate of 10.1%, both of which were quite higher
than ours17.
The
prevalence rate of Squint in our study was 4.76% with 57.30% males and 42.70%
females. The age group most commonly affected was 0-20 years with 70.79%
prevalence rate. Strabismus is a problem caused by one or more dysfunctional
eye muscles18. In a study conducted in Hayatabad medical complex Peshawar,
squint was reported in 2.0% cases which is less than ours10. In
another study conducted in Riyadh KSA, prevalence of strabismus was also less than
that of our study i.e. 1.9% vs. 4.7%19.
Globally,
the second leading cause of blindness is Glaucoma20. It is difficult
to define glaucoma precisely, partly because the term amalgamates a wide array
of diseases. All types of glaucoma have a characteristic optic neuropathy that
is associated with visual field loss as harm advances, and in which intraocular
pressure is a key factor that can be modified21,22. Our study showed
the prevalence rate of 1.66% with 61.29% males and 38.71% females. The age
group most affected was between 0-20 years.
The
ratio of glaucoma in this study was found to be low as compared to another
study conducted in Peshawar i.e. 1.66% as compared to a study conducted in Hayatabad
medical complex where the prevalence of Glaucoma was found to be 4.5%10.
Limitations of this study incorporate the study design
(retrospective), the site being of a solitary tertiary care hospital and all
information was gatered from an inpatient treatment facility. Along these
lines, a populace-based study would give more dependable information on Ocular
morbidities which would incorporate information from the general out-persistent
administrations.
CONCLUSION
Female preponderance was more than males in the sense of
general morbidity of ocular disorders. The most common eye morbidity was found
to be; Cataract which does not require any long-term medical treatment. The
second most common disease found was Pterygium which was different from most
other studies while doing the literature review. Glaucoma was found to be least
common eye morbidity in our study.
