National cancer center of Mongolia has responsibility to produce National cancer registry annual reportwhich is collected cancer reports from primary, secondary and tertiary level of government hospitals andprivate hospitals, laboratories. MCR and indicators of incidence and mortality are important for planningand evaluation of all levels for cancer control, primary prevention, diagnosis, treatment, rehabilitation.ObjectiveThe aim of this study was to determine ASR and ASMRs of cancer incidence and deaths in Mongoliafrom 2008 to 2012 for comparing the results of data.Material and MethodsData on new cancer cases diagnosed in 2008-2012 in permanent residents of Mongolia, collected bycancer registry of the National Cancer Center, were used for the analysis. Incidence and mortality rateswere calculated as mean annual numbers per 100,000 residents. ASRs (Age-standardized incidencerate) and ASMRs (Age-standardized mortality rates) were calculated by the direct method from agespecificincidence and mortality rates, weighted to the World Population standard.ResultsFirst five most frequent cancers (liver, stomach, lung, esophagus, cervix uteri) comprise 76% of all newcancer cases.In males, the most frequent cancer site was liver, followed by stomach, lung, esophageal, colon andrectal cancer. In females, liver is in the first place, followed by stomach, cervical, lung, esophagealcancer.Mean annual crude incidence rate of all cancer sites was 155 per 100 000 population,in males 165, infamale 165 in 2008-2012 years.During this period, mean annual age-standardized incidence rate of all cancer sites was 218,3 per 100000 population, for male 258.9 in female 188.1with higher percentage of men.As we age, morbidity of the cancer increases approximately 2 fold in both sexes and also study revealsmen has more tendency to have cancer than women

PURPOSE: To investigate the relationships between estimated cerebrospinal fluid pressure (CSFP) and trans-lamina cribrosa pressure difference (TLCPD) in open-angle glaucoma (OAG) in Korean population. METHODS: A total of 10,801 eyes were included from the Korean National Health and Nutrition Examination Survey V. All participants (aged 19 years or older) were classified as non-glaucomatous group, OAG suspect group and OAG group. CSFP was calculated as CSFP (mm Hg) = 0.44 body mass index (kg/m²) + 0.16 diastolic blood pressure (mm Hg) - 0.18 age (years) - 1.91. TLCPD was calculated by subtracting CSFP from intraocular pressure. RESULTS: The mean estimated CSFP was (8.7 ± 3.3 mm Hg vs. 11.6 ± 3.7 mm Hg, 11.2 ± 3.8 mm Hg vs. 11.6 ± 3.7 mm Hg) was lower, and the mean TLCPD (5.7 ± 4.4 mm Hg vs. 2.2 ± 4.4 mm Hg, 3 ± 4.7 mm Hg vs. 2.2 ± 4.4 mm Hg) was higher in the OAG group and in the OAG suspect group than in the non-glaucomatous control group, respectively (p < 0.001). After adjusting relating factor with CSFP and TLCPD using simple linear regression and multivariate analyses, the mean estimated CSFP was distributed lower (p < 0.001; beta: -0.12; B: -2.306; 95% confidence interval [CI]: -2.717, -1.895) in OAG group than in non-glaucomatous group and the mean TLCPD was distributed higher (p < 0.001; beta: 0.099; B: 1.349; 95% CI: 0.977, 1.72; p < 0.001; beta: 0.118; B: 2.776; 95% CI: 2.264, 3.289) in OAG suspect group and in OAG group than in non-glaucomatous group, respectively. CONCLUSIONS: Estimated CSFP and calculated TLCPD showed essential association with OAG presence. It supports the potential role of low CSFP in the pathogenesis of OAG.

Background:
Infectious keratitis is a disease caused by inflammation, infection, and other
ocular damage to the outer and other deep layers of corneal epithelium. It is a major cause of
monocular blindness and visual disability worldwide regardless of age and gender. Therefore, we
aimed to determine the clinical features and risk factors of infectious keratitis among Mongolians
and to identify the causative microorganism and compared them with the treatment results.
Methods:
We collected the data of 149 patients who diagnosed as infectious keratitis at the
Ophthalmology Department of the First State Central Hospital in 2017-2020 and using a case series
model of descriptive study. Statistical analysis was calculated using Stata14 software.
Results:
The majority of patients in our study were male, with a male-to-female ratio is 2.1:1. The
cause of infectious keratitis were categorized and eye injury-induced keratitis accounted for the
highest percentage of 38.3% (n=57), with the majority being men 73.7% (n=42) (p=0.028). As for the
type of treatment, antibacterial drugs 103 (69.1%) and evisceration 27(45%) predominate.
Conclusion
Our study shows that the majority of infectious keratitis in Mongolia is due to trauma
in male patients. Forty-five percent of all surgeries involve evisceration surgery, which reduces the
client's quality of life.

BACKGROUND: Pterygium is a fibrovascular wing shaped encroachment of conjunctiva
onto the cornea. Although the pathogenesis remains obscure, the ultraviolet radiations
(UVR), especially UVR-A and UVR-B (290-400 nm), are considered the most dangerous in
developing pterygium among other environmental factors (hot, dry, windy, dusty and
smoky environments and hereditary factors. The main histopathological change in primary
pterygium is elastotic degeneration of conjunctival collagen. Patient complaints include
foreign body feeling and visual loss due to corneal astigmatism or growth over the pupil and
cosmetic problems. Anti-inflammatory drugs and lubricants have an important role minimizing
the patient’s discomfort, but they do not cure the disease. After surgical removal there are
still many recurrences regardless of the method used. Autologous conjunctival grafting seems
to be the best method, given both the low recurrence rate and high safety. As described first
by Kenyon et al. in 1985, a conjunctival autograft reported a recurrence rate of 5.3% with
infrequent and relatively minor complications. The primary disadvantage of this technique
is the prolonged operative time required when compared to the bare sclera technique.
These disadvantages are outweighed by the lack of sight-threatening complications and the
relatively low recurrence rate, which made this procedure gain popularity in many centers.
The application of intraoperative 0.02% mitomycin C for the 5 minutes is efficient in reducing
the recurrence rate to a minimum.
METHODS: This retrospective case series, single center study was conducted on 239
patients, who underwent pterygium excision from Jan 2017 to Dec 2017 at the Department
of Ophthalmology of the First Central Hospital. All patients had a detailed ophthalmic
examination before the surgical intervention. Data were collected through a prepared
questionnaire. Postoperative follow-up examination sheets were evaluated. Data
for recurrence rate of pterygium excision were collected and analyzed by using SPSS version 17..
RESULTS: Among the 239 patients, who underwent an operation, 37.2% (n=89) were male and
62.8% (n=150) were female. Participants’ age ranged from 29 -70 years with mean age of 49.5
years old.
There is no statistical significance between the stages of the disease and its post-operative
outcome in the patients, who underwent pterygium excision surgery in 2017. Postoperative
pterygium recurrence was in 9 patients (3.8%); 5 (55.5%) out of all 9 patients with recurred
pterygium had underwent pterygium excision without conjunctival autograft.
MMC was not used intraoperatively for all 9 (3.8%) patients with recurrence post pterygium
excision.
CONCLUSION: The relationship between pterygium stage and its post-operative recurrence
was not statistically significant (P=0.683).
The recurrence rate after pterygium excision with conjunctival autograft was low (P≤0.001)
which showed significant statistically.
There was no recurrence after pterygium excision with MMC (P≤0.001).
The results of studies from Canada, Hong-Kong, India, Philippines and Iran were similar to our
outcome.
