   Abstract 

Aim: We aimed to determine the epidemiology and symptoms of red eyes in patients from Northern Iran. Materials and Methods: A descriptive study was planned involving 840 patients referred to the eye clinic of Bu-Ali Sina hospital in Sari, Iran, with the chief complaint of eye redness. Results: Of 840 patients, 525 were men (62.5%) and 315 were women (37.5%). Most of the patients were over 39 years of age. 55.7 percentage of them lived in cities and 44% were from villages. The most common eye symptoms with eye redness were: Eye abrasion (57%), tears in eyes (49%) and swollen eye lid (30%). Red eyes without any symptoms in eyes were diagnosed as runny nose (4.2%) and headaches (3.4%). 11.9% and 19.6% of the patients had a previous history of red eye and had visited doctors for red eyes respectively. Conclusions: Red eyes are more common in men than women. Introducing dangerous causes of red eyes in the future can help to health care professional to on time diagnosis of red eyes related problems.

   Introduction Top


Eye redness is the result of inflamed blood vessels in eyes [1],[2] and is one of the most common complaints with which patients are referred to eye clinics or emergency units. [3],[4],[5] Incidentally red eyes are not always the symptoms of an illness [7] nevertheless it can be deleterious often leading to serious visual problems. [6] Hence, red eyes should be diagnosed at an as early stage as possible, [3],[8] based on ocular symptoms such as visual abnormalities, abnormalities in eye appearance, eye sensory abnormalities (pain) [2] photophobia and ciliary flash. [9],[10] Since red eyes are one of the main reasons and symptoms of eye inflammation and one of the most common complaints in outpatients units, we analyzed the epidemiology and symptoms of red eyes in patients from our region (northern Iran). Specifically we determined the prevalence of red eyes and related factors in Bu-Ali Sina hospital in Sari, Iran. We believe our data will provide valuable inputs into taking effective steps for treating red eyes and prevent their associated serious effects.

Sampling

A descriptive study was planned involving 840 patients referred to the eye clinic of Bu-Ali Sina hospital in Sari, Iran from 2012 to 2013. The samples selected according the previous studies. [11],[12] The study was approved by ethics committee of Mazandaran university of Medical Science and signed consent was obtained from all patients before the study. Complete history of the patients and examinations were recorded by the Oculists.

Tools

The equipment used to examine included flashlights to examine the pupils, snalen chart to test vision acuteness, Ophthalmoscope, fluorescence paper and slit lamps. All parts of both eyes were examined, and symptoms such as eye redness and color change of eyes and increase of conjunctive vessels determined by slit lamps were documented. Eye movements and eyesight were also examined. Data collecting tools included information forms to get patients demographic information (such as age, sex, job and living place) and information on factors related to eye redness such as exact location of eye redness, duration of eye redness from the beginning to diagnosis of the factors, manner of onset and symptoms of red eyes. Ophthalmological clinical finding and the reasons leading to red eyes, medical background such as diabetes, hypertension, lipid abnormalities, thyroid abnormalities, red eye background, referring to oculists, taking drugs under supervision of oculists or on their own, first (interviews) and final (ophthalmological examination) diagnoses were recorded. The validity of the information forms contents was confirmed by Ophthalmological professors of Sari Medical College. The methods were described and explained to all patients. There were no clinical risks and also no limitation to the patients.

Statistics

The data were analyzed using descriptive statistical and analytical tests in SPSS (IBM Corp. Released 2011. IBM SPSS Statistics for Windows, Version 20.0. Armonk, NY) software.


   Results Top


Of the 840 patients participating in the study, 525 were male (62.5%) and 315 were female (37.5%). 394 of them (46.9%) were over 39 years old, 331 (39.4%) between 15 and 39 and 115 (13.69%) were under 15 years of age. The most common Ophthalmological symptoms with eye redness were; eye irritation (484 patients 57%), tearful eye (414 patients, 49%), swelling of eyelid swelling or edema (259 patients 30%), feeling of external objects in their eyes (192 patients, 22%), pain in eyes (188 patients 22%) and itching sensation (180 patients, 21%) [Figure 1]. The ophthalmological symptoms of red eyes, feelings of external objects, pains, itches, and reduction of vision acuteness had a higher prevalence among the age group of over 39 years [Table 1].

Non ophthalmological symptoms of red eyes in the patients observed were 36 cases of runny noses (4.2%), 29 cases of headaches (3.4%), 9 cases had fever (1%), 6 cases had lymphadenopaty (0.7%), and 4 cases of vertigo (0.4%). Of these symptoms of red eyes, headache had meaningful statistical relation to age, and it had a higher prevalence in age group of over 39 years [Table 2].

In their medical history, 165 patients (19.6%) had the records of recent reference to oculists, 100 patients (11.9%) had red eyes in the past, 77 patients (9.1%) had records of hypertension, 62 patients (7.3%) had diabetes, 39 patients (4.6%) had lipid disorders, 19 patients (2.2%) had cold, 13 patients (1.5%) had thyroid disorders, 3 patients (0.3%) had allergies, 2 patients (0.2%) had migraine, and 21 patients (2.5%) had other diseases. In medical history and backgrounds, there was a meaningful statistical relation among red eyes records, diabetes, hypertension, lipid disorders and age with more prevalence in patients over 39 years of age. From the aspect of taking ophthalmological drugs, 188 patients (22.3%) had recent records of being on medication, of those drugs, 107 patients (12.7%) took Nephazoline, 85 patients (10.1%) took Cleramephnicle, 67 patients (7.9%) took Bethamethazone, 16 (1.9%) took artificial tears, 7 patients (0.8%) took Ciprofloxacine, 5 patients (0.5%) took Cortone and 39 patients (4.6%) took other drugs.


   Discussion Top


In this research, the patients were divided into 3 age groups of 0-15-year-old, 16-39 years old and over 39 years. The group of over 39 years had the most distribution of frequency (394 patients, 46.9%), which is consistent with previous reports. [3],[11],[12] Red eyes is a common condition reported among the population from Middle East with an incidence rate of up to 40%, [13],[14] which is significantly higher than data reported from European (6-15%) [14] or Nigerian (14.8%) population. [3]

Previously, prevalence of petrygium in patients over 50 was is reported to be 33.1% with higher prevalence in women (35.7%) than in men (29.7%). [15] During an hemorrhagic conjunctivitis epidemic in Nepal, 30.5% of the patients were between 20 and 29 years of age and higher prevalence was observed among men. [16] In the present study, 55.7% of the patients were from urban areas and 44% from rural regions, which is not consistent with other reports. [12] In the present study, the most prevalent Ophthalmological symptoms with red eyes were, eye irritation with frequency of 57%, tears in eye 49%, swollen eyelids 30%, which again is not consistent with previous reports, [11],[12],[17],[18] and probably indicates a changing trend in the prevalence of red eyes. The nonophthalmological symptoms of red eyes were runny noses (4.2%) and headaches (3.4%). A runny nose was in most cases associated with feeling of external objects and allergic conjunctivitis and most headaches were associated with glaucoma. In the present study, 6 patients referred with fever (0.7%) while in previous reports (2011) 8% of the children had a fever. [12] The higher prevalence in people over 39 years of age observed in our study, may be because of more prevalence of migraine and hypertension in this group. From the aspect of medical history and background, incidence of diabetes, hypertension and lipid disorder were higher among patients with red eyes, with higher prevalence in over 39 years old. In the present study, Nephazoline drops were the commonly used prescription medication mainly in patients under 15 years of age. We conclude that red eyes that are common condition for patients are referred to emergency units is more prevalent in men than in women. Appropriate training for the exact diagnosis of high-risk symptoms of eye redness is necessary to reduce the serious vision problems in future.
