The stereo-structure of the orbit is affected by several orbital diseases, e.g. congenital orbital dysplasia, orbital fracture, and intraorbital tumor. The three-dimensional (3D) reconstruction technique serves as a practical tool in diagnosis, surgical planning, and outcome prediction of plastic and reconstructive surgery. In our study, the morphologic features of the Mongolianadult orbit were described by 11 anatomic parameters using a 3D reconstruction technique and quantitative morphometry. The morphologic parameters of orbit such as bony orbital volume, orbital foramen area and orbital rim perimeter were measured on 3D models using this technique. Three-dimensional (3D) reconstruction based on high-resolution spiral computed tomography (CT) scans has been used for more than 10 years to reveal the anatomic location and morphologic features of orbital abnormalities and plays a important role in diagnosis, surgicalplanning, and outcome prediction. The findings of the study would allow for quantification of the orbital features of Mongolian adults and provide parameters for preoperative planning and prediction of postoperative outcome.

LASIK is the most popular treatment method for correction of the refractive errors of ophthalmology its development in 1990 and number of patients has continued to increase.The safety and efficacy of LASIK surgery have been reported several times by numerous researchers and doctors, but all studies have made abroad. This time we have summarized postoperative outcomes of LASIK surgery, which have performed in our country. Consequently 103 patients (206 eyes) who underwent LASIK surgery in “Bolor-Melmii” eye clinic between 2007 and 2011 were enrolled. The retrospective method of study was used to evaluate postoperative outcomes. Preoperative UCVA of 0.04-0.4 improved to 0.5-1.2(decimal) at 1 day after surgery and during 1 year after surgery revealed minimal but wasstable. Preoperative mean sphere equivalent of 2.2+/-0.72D improved at the 1 year by +/-0.5D in 161 eyes (78.15%), by +/-1.0D in 39 eyes (18.9%) and by +/-2.0D in 6 eyes (2.9%)after surgery. Mean sphere equivalent and astigmatism improved to -0.46 +/-0.4D and -0.43+/-0.34D respectively at 1 year after surgery. Improvement of the sphere equivalent and its stability during a year period of study proves that LASIK surgery is an effective with stable improvements and safe procedure for correcting myopia/myopic astigmatism. No severe complications occurred during and after surgery.

Aim:
The aim was to determine etiology and clinical presentation of pediatric cataract during 1
year period
Methods:
NCMCH is tertiary and referral center for all pediatric patients with cataracts in 21
provinces and UB. Database contains cases during 1 year period. We have recorded the
following data from the medical histories of these patients: family history, current age, age at
diagnosis, age at surgery either eye, morphology of cataracts, laterality, associated findings and
other investigations which were performed as clinically indicated. We have operated 80 children
in total during 1 year period, however the study included 68 patients (91), eyes excluding 12
patients.
Results:
Of 68 children with cataract 76.% were non traumatic, 21,15% hereditary, 51,9% were
congenital/infantile, 35.8% were unilateral, 44% were associated other ocular findings, 25%
were associated systemic disease. 33.3% were diagnosed and operated 0-12 months. 73% of
congenital/infantile cataract patients were nystagmus. Of traumatic cataract 76,5% due to
penetrating trauma.
Conclusions
Patients of pediatric cataract 1/3 were usually diagnosed in 0-12 months. 1/3
of these patients were diagnosed congenital cataract whereas 1/4 were nystagmus. To add up
associating congenital/infantile cataract with Down syndrome weren’t rare.

To evaluate the efficacy and safety of bevacizumab monotherapy or combined with laser versus laser monotherapy in Mongolian patients with visual impairment due to diabetic macular edema.Prospective, randomized, single-center, a 12 month, laser-controlled, clinical trial. Participants: One hundred twelve eligible patients, aged ≥18 years, with type 1 or 2 diabetes mellitus and best corrected visual acuity (BCVA) in the study eye of 35 to 69 Early Treatment Diabetic Retinopathy Study (ETDRS)letters at 4 m (Snellen equivalent: ≥6/60 or ≤6/12), with visual impairment due to center-involved diabetic macular edema (DME). Methods: Patients were randomized into three treatment groups:(I) intravitreal bevacizumab monotherapy (n=42), (II) intravitreal bevacizumab combined with laser (n=35), (III) laser monotherapy (n=35). Bevacizumab injections were given for 3 initial monthly doses and then pro re nata (PRN) thereafter based on BCVA stability and DME progression. The primary efficacy endpoints were the mean change in BCVA and central retinal subfield thickness (CRST) from baseline to month 12.Bevacizumab monotherapy or combined with laser were superior to laser monotherapy in improving mean change in BCVA letter score from baseline to month 12 (+8.3 and +11.3 vs +1.1 letters; both p<0.0001). There were significant difference detected between the bevacizumab and bevacizumab combined with laser treatment groups (p=0.004). At month 12, greater proportion of patients gained ≥10 and ≥15 letters and with BCVA letter score >73 (Snellen equivalent: >6/12) with bevacizumab monotherapy (23.8% and 7.1% and 4.8%, respectively) and bevacizumab + laser (57.1% and 28.6% and 14.3%, respectively) versus laser monotherapy. The mean central retinal subfield thickness was significantly reduced from baseline to month 12 with bevacizumab (−124.4 μm) and bevacizumab + laser (−129.0 μm) versus laser (−62.0 μm; both p<0.0001). Conjunctival hemorrhage was the most common ocular events. No endophthalmitis cases occurred.Bevacizumab monotherapy or combined with laser showed superior BCVA improvements over macular laser treatment alone in Mongolian patients with visual impairment due to diabetic macular edema.

Kidney transplantation is the best alternative treatment for end-stage renal disease and health-related quality of life and survival of the patients are improved compared with dialysis. Worldwide, more than 1.4 million patients with CKD receive renal replacement therapy with incidence growing by approximately 8% annually.1 Unfortunately, despite significant improvement in graft function, kidney transplants can still fail due to acute rejection and chronic allograft nephropathy.2 Kidney biopsy after transplantation, which has evaluated by Banff 09 classification is usefull method for diagnose of transplanted kidney disease.3,4Kidney graft rejection was diagnosed in 10 renal allograft biopsy specimens (bs) obtained from transplant patients followed up at our institute between 2015 and 2016. All specimens were evaluated as satisfactory which show more than 8 glomerulus under the light microscopy. Each renal cortical tissue was divided into two tips: one piece for routine H&E stain and special stains, including Masson’s trichrome, and PAS stain; another piece for immunofluorescence by frozen section, which were stained with IgA, IgM, IgG and complement component (C3, C4, C1q, C4d). All the renal biopsies were examined by the same pathologist.Out of 117 transplantations, 10 episodes of rejection selected. Among the 10 patients, 30% had an acute T cell rejection and 70% had a chronic allograft nephropathy. Interstitial inflammation (i1-7) was present in 7 bs (70%), tubulitis (t1-4,t2-2) in 6 bs (60%), transplant glomerulitis (g1-1, g2-2, g3-1) in 4 bs (40%), transplant interstitial fibrosis (ci1-2, ci2-2, ci3-2) in 6 bs (60%), tubular atrophy (ct1-6, ct2-2, ct3-1) in 9 bs (90%), mesangial matrix increase (mm1-5) in 5 bs (50%), vascular fibrosis intimal thickeness (cv1-3) in 3 bs (30%), arteriolar hyaline thickening (ah1-5) in 5 bs (50%), tubulitis (ti1-6, ti2-3, ti3-1) in 10 bs (100%) and peritubular capillaritis (ptc1-1, ptc2-2, ptc3-1) in 4 bs (40%). C4d deposition was present very mild in wall of the vessels and peritubular capillaries. Because of not good working Methenamin silver stain, we couldn’t demostrate glomerular basement membrane changes (cg) fully.We suggest that histopathological changes of transplant glomerulopathy might be accompanied by inflammation of the microvasculature, such as transplant glomerulitis and peritubular capillaritis. C4d deposition in the wall of the vessels and peritubular capillaritis is not always present in biopsy specimens of transplant glomerulopathy.

Background:
TED (thyroid eye disease) is an inflammatory disease of the orbit caused by
autoimmune diseases of the thyroid, which adversely affect the vision, appearance, and quality
of life. Exophthalmos and eyelid retraction are the main features of TED, which can lead to ocular
motility, diplopia, optic neuropathy, and permanent vision loss. The study aims to determine the
most common clinical signs of TED in Mongolians and define whether there is a correlation with
the levels of thyroid autoantibodies.
Methods:
The study involved 102 patients with TED and 81 patients with Graves’ ophthalmopathy.
The clinical features of TED were identified and evaluated by activity score (CAS) and severity of
GO using the European Group of Graves’ Orbitopathy (EUGOGO).
Results:
The mean age of TED patients was 42.6±11.2, which was younger than GD patients
(P=0.012). The current smoker was 24 patients (23.5%) with TED, which is relatively higher than GD
(P=0.0001). The most common ocular signs were eyelid retraction 80 (78.4%), proptosis 77 (75.5%),
diplopia 14 (13.7%) and 4% vision loss. There were no differences in proptosis between the right (18
mm, median) and left eye (17.8 mm, median) (P>0.05). The mean CAS score was 3.09±1.72 and
varied depending on gender and smoking. According to EUGOGO, 62.7% of the patients were
moderately severe. Only 7 % of the patients were in the sight-threatening stage, presenting optic
neuropathy and corneal breakdown. The mean TSI level in patients with TED was 37.95 ± 35.41 IU
/ ml, which was 2.7 times higher than the mean in patients with GD.
Conclusions
Eyelid retraction and exophthalmos are the most common clinical signs of TED.
Early diagnosis of these features can prevent complications of the disease. Determining serum TSI
levels will help in the treatment and monitoring of TED.
