1.  Conjunctival Inclusion Cysts in Long-standing Chronic Vernal Keratoconjunctivitis 
Purpose
To report a case of conjunctival inclusion cysts on the corneal limbus of a patient with chronic vernal keratoconjunctivitis during 16 months' follow up
Methods
The patient was a 26 year old male without any specific history of surgery or trauma. Giant papillae, shield ulcers, and Horner-Trantas dots were detected. During the 16 month follow-up, Sodium cromoglycate eye drops and Prednisolone acetate 1% eye drops were given 3 times a day. During this period, conjunctival cysts were detected on the corneal limbus in both eyes. In spite of improvement of the corneal and conjunctival conditions, the conjunctival cysts did not seem to show any specific changes. For relief of foreign body sensation, excision of the conjunctival cysts and giant papillae of the left eye and histopathologic examination of the specimen was performed.
Results
On histopathological examination, the conjunctival cysts consisted of nonkeratinizing stratified epithelial cells filled with PAS-positive mucous substance. Inflammatory cells were not found in the vicinity.
Conclusions
Conjunctival inclusion cysts can be seen as an atypical finding of long-standing vernal keratoconjunctivitis. Mechanical friction between the giant papillae and conjunctiva may be a factor in inducing the formation of the conjunctival cysts.

2.  Bilateral Peripheral Infiltrative Keratitis After LASIK 
Purpose
To present a case of peripheral infiltrative keratitis mimicking infectious keratitis on the flap margin and limbus, which appeared on the first postoperative day after the laser in situ keratomileusis (LASIK).
Methods
A 36-year-old woman who underwent uneventful bilateral simultaneous LASIK developed multiple round infiltrate along the flap margin reaching to limbus from the 11 o'clock to 6 o'clock area in both eyes.
Results
The flap was lifted and irrigation was performed with antibiotics. but infiltration seemed to appear again. The infiltrate was more concentrated at the periphery and was extended to the limbus. Direct smear and culture for bacteria and fungus were negative. Topical prednisolone acetate 1% eye drops was added, infiltrative condition was resolved.
Conclusions
LASIK induced peripheral infiltrative keratitis, in which infectious origin was ruled out, is reported

3.  Effect of fibrin glue as an adjuvant to hang-back surgery 
BMC Ophthalmology  2012;12:14.
Background
The hang-back surgery is a useful technique in the field of strabismus surgery. The aim of this study is to determine the stabilizing effects of fibrin glue as an adjuvant to hang-back surgery.
Materials and methods
Four (4)-mm hang-back recessions of the superior rectus muscle was performed in 32 eyes of 16 rabbits. Only in the left eye of the 16 rabbits, fibrin glue was applied between the recessed muscle bed and the sclera at the end of hang-back surgery (fibrin glue group). After 6 weeks, we compared the stability of the recessed rectus muscle between the fibrin glue group and the control group by evaluating the displacement of the muscle.
Results
The frequency of stable insertion of the recessed muscle at the intended site was greater in the fibrin glue group (9 eyes) compared to the control group (3 eyes) (p = 0.028). In the control group, 5 eyes showed anterior displacement and 8 eyes showed posterior displacement and in the fibrin glue group, 1 eye showed anterior displacement, and 6 eyes showed posterior displacement. Anterior displacement was more common in the control group (6.3% Vs 31.3%). The control group and the fibrin glue group showed similar histological findings on microscopic examination.
Conclusions
Fibrin glue is effective in stabilizing the new rectus muscle insertion and decreasing the displacement in the hang-back surgery.
